In Cox regression analysis controlling for other factors impacting outcome, there was a significantly increased risk of mortality (HR 2.11; P = .027; 95% CI 1.09-4.09) but not pulmonary recurrence (HR 0.96; P = .90; 95% CI 0.52-1.79) with a thoracoscopic approach. However, in the subset analysis limited to patients with oligometastatic disease, thoracoscopy had no increased risk of mortality (HR 1.16; P = .62; 0.64-2.11). In conclusion, patients with metastatic osteosarcoma and limited pulmonary disease burden demonstrate comparable outcomes after thoracotomy and thoracoscopy for metastasectomy. While significant selection bias in these surgical cohorts limits the generalizability of the conclusions, clinical equipoise for a randomized clinical trial in patients with oligometastatic disease is supported.We propose a new highly flexible and tractable Bayesian approach to undertake variable selection in non-Gaussian regression models. It uses a copula decomposition for the joint distribution of observations on the dependent variable. This allows the marginal distribution of the dependent variable to be calibrated accurately using a nonparametric or other estimator. The family of copulas employed are "implicit copulas" that are constructed from existing hierarchical Bayesian models widely used for variable selection, and we establish some of their properties. Even though the copulas are high dimensional, they can be estimated efficiently and quickly using Markov chain Monte Carlo. A simulation study shows that when the responses are non-Gaussian, the approach selects variables more accurately than contemporary benchmarks. A real data example in the Web Appendix illustrates that accounting for even mild deviations from normality can lead to a substantial increase in accuracy. To illustrate the full potential of our approach, we extend it to spatial variable selection for fMRI. Using real data, we show our method allows for voxel-specific marginal calibration of the magnetic resonance signal at over 6000 voxels, leading to an increase in the quality of the activation maps.The complex interplay between ultraviolet radiation (UVR) and cutaneous viral infections in the context of cancer etiology is challenging to unravel, given the limited information on the independent association between UVR and cutaneous viral infections. Using multiple biomarkers of infection with 24 types of cutaneous human papillomavirus (HPV) and 4 types of polyomaviruses (HPyV), we investigated cross-sectional associations with recent UVR exposure, using skin pigmentation measured by spectrophotometer. Age- and sex-adjusted associations between UVR and viral seropositivity, viral DNA present in eyebrow hairs (EBH) and skin swabs (SSW) were estimated using logistic regression. Beta-HPV seropositivity was associated with viral DNA positivity in EBH (OR = 1.40, 95% CI = 1.05-1.88) and SSW (OR = 1.86, 95% CI = 1.25-2.74). Similar associations were observed for Merkel cell polyomavirus. Participants in the highest tertile of UVR exposure were more likely to be seropositive for beta-HPV (OR = 1.81, 95% CI = 1.16-2.38), and have beta-HPV DNA in EBH (OR = 1.57, 95% CI = 1.06-2.33) and SSW (OR = 2.22, 95% CI = 1.25-3.96), compared to participants with the lowest tertile of UVR exposure. UVR exposure was positively associated with three different markers of beta-HPV infection. Therefore, future studies of HPV associated KC development should address more directly the role of HPV and UVR exposure as potential co-carcinogens.The current study presents two different approaches with a view to elucidating the interaction between thyroid hormones (TH) and apo-transferrin (aTf) and their role in myelination and remyelination. First, in vitro assays were conducted to determine the single and combined effects of aTf and triiodothyronine (T3) on oligodendroglial cell lineage proliferation and oligodendrocyte (OLG) maturation in primary cultures. Results revealed higher proliferation rates upon single aTf treatment but Control values upon T3 and aTf + T3 treatments. In addition, both aTf and T3 accelerated OLG maturation, with the greatest effects being exerted by combined aTf + T3 administration in terms of both myelin basic protein (MBP) expression and morphological complexity. Second, in vivo assays were carried out to establish single and combined effects of aTf and T3, as well as TH receptor (THR) inhibitor I-850, on remyelination following a CPZ-induced demyelination protocol. Results showed an increase in myelin deposition and the number of mature remyelinating OLG upon single treatments, but a synergic effect upon combined aTf + T3 treatment which was prevented by THR inhibition. It may be thus concluded that combined treatment yielded the most beneficial effects on OLG maturation parameters in vitro and remyelinating capacity in vivo when compared to single treatments. These findings may help explore the development of new target molecules in the treatment of demyelinating diseases.Withdrawal Primary prevention of sickle cell disease using preimplantation genetic testing and in vitro fertilization is cost-effective. The above article, published online on 20 August 2020 in Wiley Online Library (wileyonlinelibrary.com) as an Accepted Article, has been withdrawn by agreement between the authors, the journal Editor in Chief, and John Wiley & Sons Ltd. https://www.selleckchem.com/products/gw0742.html The article has been withdrawn after the accepted article was posted online, the authors received independent feedback that has prompted them to review their analysis in the article to ensure that the original conclusions are accurate.Desirable system performance in the face of threats has been characterized by various management concepts. Through semistructured interviews with editors of journals in the fields of emergency response and systems management, a literature review, and professional judgment, we identified nine related and often interchangeably used system performance concepts adaptability, agility, reliability, resilience, resistance, robustness, safety, security, and sustainability. A better understanding of these concepts will allow system planners to pursue management strategies best suited to their unique system dynamics and specific objectives of good performance. We analyze expert responses and review the linguistic definitions and mathematical framing of these concepts to understand their applications. We find a lack of consensus on their usage between interview subjects, but by using the mathematical framing to enrich the linguistic definitions, we formulate comparative visualizations and propose distinct definitions for the nine concepts. We present a conceptual framing to relate the concepts for management purposes.
Skeletal muscle relaxation has been primarily studied by assessing the kinetics of force decay. Little is known about the resultant dynamics of structural changes in myosin heads during relaxation. The naturally occurring nucleotide 2-deoxy-ATP (dATP) is a myosin activator that enhances cross-bridge binding and kinetics. X-ray diffraction data indicate that with elevated dATP, myosin heads were extended closer to actin in relaxed muscle and myosin heads return to an ordered, resting state after contraction more quickly. Molecular dynamics simulations of post-powerstroke myosin suggest that dATP induces structural changes in myosin heads that increase the surface area of the actin-binding regions promoting myosin interaction with actin, which could explain the observed delays in the onset of relaxation. This study of the dATP-induced changes in myosin may be instructive for determining the structural changes desired for other potential myosin-targeted molecular compounds to treat muscle diseases.

Here we umay affect soleus muscle relaxation. X-ray diffraction evidence indicates that with elevated dATP, myosin heads were extended closer to actin in resting muscle. Following contraction, there is a slight but significant delay in the decay of force relative to WT muscle while the return of myosin heads to an ordered resting state was initially slower, then became more rapid than in WT muscle. Molecular dynamics simulations of post-powerstroke myosin suggest that dATP induces structural changes in myosin that increase the surface area of the actin-binding regions, promoting myosin interaction with actin. With dATP, myosin heads may remain in an activated state near the thin filaments following relaxation, accounting for the delay in force decay and the initial delay in recovery of resting head configuration, and this could facilitate subsequent contractions.Gastric cancer (GC) is the sixth most common malignancy and the third leading cause of cancer-related death worldwide. Emerging evidence suggests that tumour microenvironment cells play a vital role in the development and prognosis of GC. To investigate the possible effect of stromal scores and immune scores on the overall survival (OS) on the GC patients, we divided GC patients into 'high' and 'low' groups based on their stromal and immune scores, and found differentially expressed genes related to prognosis of GC patients. Functional enrichment analysis and GSVA further revealed that focal adhesion and ECM-receptor interaction are associated with GC patients' survival. Finally, we analysed the effects of genes commonly involved in focal adhesion and ECM-receptor interaction on GC patients' survival and validated our results in another GC cohort from GEO data sets. In conclusion, we obtained a list of tumour microenvironment-related genes that predict poor prognosis in GC patients.Familial Mediterranean fever (FMF) is a recessive autoinflammatory disease, mainly occurring in the eastern Mediterranean. In these populations, the five FMF founder mutations are differently distributed. In Algeria, the FMF-causing variants remain poorly explored. This retrospective study aims to report the mutational profile of Algerian FMF patients and to compare it with North African FMF patients. One hundred eighty-three unrelated patients clinically suspected of FMF were recruited from various Algerian hospitals (2007-2015) and tested for mutations in exon 10 of MEFV gene. Molecular analysis identified 144 mutant alleles among 87 of 183 patients (47.5%). p.M694I was the most prevalent pathogenic allele, accounting for 63.2% of mutant alleles, followed by p.M694V and p.M680I occurring with a same frequency (14.5%). Others, p.A744S (6.2%) and p.I692del (1.3%), are less frequent. Interestingly, p.M694I was the most recurrent in patients with renal AA-amyloidosis. Our results provide the first genetic data on FMF in Algeria, demonstrating the predominance of p.M694I and the absence of p.V726A, compared to other North African countries (Morocco, Tunisia, and Egypt). In conclusion, North African FMF patients display differential mutational profiles that may result from the difference in ethnic origin and the genetic heterogeneity among these populations.Verbal aggression victimization, such as homophobic name-calling, has been linked to heavier substance use among young people, but little longitudinal research has examined how different types of victimization may affect substance use or whether certain psychosocial factors moderate these risks. In a diverse cohort (N  = 2,663), latent transition analysis was used to model heterogeneity in victimization (age 19) and substance use (age 20). Four victimization (high victimization, homophobic name-calling only, verbal sexual harassment only, and low victimization) and three substance use (poly-substance use, alcohol, and cannabis only, low all) classes were identified. The high victimization and homophobic name-calling only classes had the highest probabilities of transitioning into the poly-substance use class, and the high victimization class had the highest probability of transitioning into the alcohol and cannabis only class. The probability of transitioning into the low all substance use class was highest in the low victimization class and lowest in the high victimization class.

Background The prevalence of sexually transmitted diseases is an important public health problem, especially in people who are sexually active, such as the army conscript group. However, their knowledge, attitudes, and practices may be influenced by certain cultures and beliefs. This study explored the factors associated with the risk of human immunodeficiency virus (HIV)/sexually transmitted infections (STIs) among the Muslim army conscript in three deep southern provinces of Thailand. Methods The cross-sectional study design was conducted among 360 Muslim army conscripts. A researcher made questionnaire on knowledge of HIV/STI transmission, attitude toward condom use, and sexual behavior was distributed to the participants in a camp base. The association between the potential predictor variables and the risk of HIV/STI was analyzed using the multiple logistic regression. Statistically significant of the association considered a P value ≤ 0.05. https://www.selleckchem.com/products/brivudine.html Results The results suggest that most Muslim army conscripts had a poor knowledge level of HIV/STI transmission (78.7%) and that their attitude toward condom use was at a moderate level (60.0%). The predicted factors were marital status [aOR=0.078, 95% CI=0.035-0.172], substance use before having sex [aOR=8.044, 95% CI=1.288-50.230], stimulant use before having sex [aOR=3.632, 95% CI=1.080-12.211], vaginal sexual intercourse [aOR=26.228, 95% CI=8.370-82.189], and oral sexual intercourse [aOR=2.256, 95% CI=1.106-4.601]. Conclusion A proper sexual health education program should be developed and delivered to enhance knowledge on HIV/STI transmission among Muslim army conscripts.Background More than 4.2 million cases of diabetes mellitus (DM) were reported in Thailand during 2019. Medication adherence is necessary to delay disease progression and prevent complications among uncontrolled type 2 DM patients. The objective of this research was to study how education via the Line application and telephone-based counseling impacted medication adherence knowledge by analyzing the behavior of uncontrolled type 2 diabetic patients. Methods Uncontrolled type 2 DM patients in Doi Saket Hospital, Doi Saket district, Chiang Mai province, Thailand. were included in the study. The sample was divided into an experimental (n=30) and control group (n=30). Patients who met the inclusion criteria of having uncontrolled type 2 diabetes diagnosed by a physician for at least one year, capable of communicating in Thai, possessing a mobile phone with the Line application and able to partake in activities for eight weeks were recruited in the parallel-group randomized trial. The experimental group participatLine application and telephone-based counseling program improved medication adherence knowledge and behavior among uncontrolled type 2 DM patients. Other outcomes of social media interactions such as patient engagement, patient behavior and attitudes, and the efficacy of patient-health care provider communication levels are possible areas for future study.The acceptance of the coronavirus disease 2019 (COVID-19) vaccine has been described as a gateway to attaining herd immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The critical role of community participation (CP) has been successfully demonstrated in previous vaccination programs globally. This perspective therefore aimed to describe how CP could be used to promote COVID-19 vaccination acceptance. To promote COVID-19 vaccine acceptance, it is required that a mapping of community assets, resources, civil-based organizations, and stakeholders is done to gain insight into the community culture and value in relation to COVID-19 vaccine. This will help to address the misconceptions while prompting COVID-19 vaccination sensitization activities that are relevant to each community. It is required that policy makers understand that the adoption of a comprehensive grassroots approach lends a voice to the community and helps to utilize community-initiated and community-driven ideas on promoting COVID-19 vaccine acceptance.Health care services and programs directed towards combating the neglected tropical diseases (NTDs) have been disrupted because of the impact of the coronavirus disease 2019 (COVID-19). The African continent because of its staggering health care system and poor economy disproportionately bears the burden of these diseases. While successes have been recorded in controlling and eliminating the NTDs, policymakers in Africa should consider the potential of the COVID-19 to dwindle these successes an issue of high priority. This commentary seeks to discuss the current status of NTDs in Africa and proffer recommendations to help combat these diseases at this period. It is worthy to say that similar dedication directed towards fighting the COVID-19 should also be deployed into eliminating other diseases like the NTDs which often, are neglected.The United Kingdom has one of the highest teenage birth rates among countries in western Europe. Government initiatives such as the Teenage Pregnancy Strategy introduced by the labor government in 1999 to reduce the teenage pregnancy rate by half in ten years could be responsible for the steady decline in teenage conception and childbirth for the past two decades. However, to sustain this decrease it is crucial to consider the broader socioeconomic and environmental determinants of teenage pregnancy at the population level. A selected literature search was conducted in this respect to highlight the factors that could be neglected by recent interventions on teenage pregnancy and childbirth in the United Kingdom.Background Considering limitations of the established osteoarthritis (OA) medications, attention to adjuvant and complementary treatments has increased in OA individuals. Recent investigations have reported advantages of pomegranate in OA and indicate that pomegranate can be a therapeutic option; nevertheless, no systematic review exists regarding OA and pomegranate. Therefore, we systematically studied accessible researches regarding pomegranate and OA in human, animal, and in vitro models and likely mechanistic pathways. Methods Present systematic review study was recorded on the international prospective register of systematic reviews database. Electronic databases (Scopus, PubMed, Embase, WOS, ProQuest) and search engine Google Scholar were searched until February 2021. Search alerts were turned on to recognize papers published following the primary search. Two investigators independently searched using MESH and non-MESH words in title, abstract, and keywords. Inclusion criteria were related clinical, animal, and in vitro studies published in any language as a full text. Exclusion criteria were reviews, book chapters, conference abstracts, and articles regarding pomegranate in health problems other than OA. Hand searching was used to check the references or citations of eligible papers and grey literature (theses etc.) to find potential researches. Results Twenty-three articles were included in our systematic review. Human, animal, and in vitro researches demonstrated favorable properties of pomegranate in improving clinical features and reducing inflammatory, oxidative stress, and apoptosis markers in OA. Conclusion Present paper provides convincing evidence about the efficacy of pomegranate in OA and gives a justification for the importance of additional clinical studies.Background Sedentariness is a substantial risk for many chronic diseases. We aimed to investigate the correlation of sedentary behavior and its indicators with low back pain (LBP) among adults and children. Methods Original articles published up to April 28, 2020, using PubMed, Embase, Web of Science and Scopus were evaluated. Odds ratio (OR, 95% CI) was considered the overall effect size for desired associations. Results We reviewed 49 English articles with analytical observational study design, of which, 27 studies with cross sectional/survey design were retained in the meta-analysis. Among adults, sedentary lifestyle was a considerable risk factor for LBP (OR=1.24, 1.02-1.5); prolonged sitting time (OR=1.42, 1.09-1.85) and driving time (OR=2.03, 1.22-3.36) were the significant risk factors. Sedentary behavior was associated with LBP in office workers (OR=1.23). Moreover, excess weight (OR=1.35, 1.14-1.59) and smoking (OR=1.28, 1.03-1.60) were associated with LBP. Among children, sedentary lifestyle was a remarkable risk factor for LBP (OR=1.41, 1.24- 1.60); prolonged TV watching (OR=1.23, 1.08-1.41) and computer/mobile using and console playing time (OR=1.63, 1.36-1.95) were significant risk factors for LBP. Consumption of coffee, however, has yield conflicting results to be considered as a risk factor. Moreover, the researches on the correlation between sedentariness and high-intensity LBP are scarce and inconclusive. Conclusion Sedentary behavior, whether in work or leisure time, associates with a moderate increase in the risk of LBP in adults, children and adolescents.Background Surveillance forms the basis for response to disease outbreaks, including COVID-19. Herein, we identified the COVID-19 surveillance systems and the associated challenges in 13 African countries. Methods We conducted a comprehensive narrative review of peer-reviewed literature published between January 2020 and April 2021 in PubMed, Medline, PubMed Central, and Google Scholar using predetermined search terms. Relevant studies from the search and other data sources on COVID-19 surveillance strategies and associated challenges in 13 African countries (Mauritius, Algeria, Nigeria, Angola, Cote d'Ivoire, the Democratic Republic of the Congo, Ghana, Ethiopia, South Africa, Kenya, Zambia, Tanzania, and Uganda) were identified and reviewed. Results Our findings revealed that the selected African countries have ramped up COVID-19 surveillance ranging from immediate case notification, virological surveillance, hospital-based surveillance to mortality surveillance among others. Despite this, there exist variations in the level of implementation of the surveillance systems across countries. Integrated Disease Surveillance and Response (IDSR) strategy is also being leveraged in some African countries, but the implementation across countries remains uneven. Our study also revealed various challenges facing surveillance which included shortage of skilled human resources resulting in poor data management, weak health systems, complexities of ethical considerations, diagnostic insufficiency, the burden of co-epidemic surveillance, and geographical barriers, among others. Conclusion With the variations in the level of implementation of COVID-19 surveillance strategies seen across countries, it is pertinent to ensure proper coordination of the surveillance activities in the African countries and address all the challenges facing COVID-19 surveillance using tailored strategies.Background The rapid circulation of arboviruses in the human population has been linked with changes in climatic, environmental, and socio-economic conditions. These changes are known to alter the transmission cycles of arboviruses involving the anthropophilic vectors and thus facilitate an extensive geographical distribution of medically important arboviral diseases, thereby posing a significant health threat. Using our current understanding and assessment of relevant literature, this review aimed to understand the underlying factors promoting the spread of arboviruses and how the three most renowned interdisciplinary and holistic approaches to health such as One Health, Eco-Health, and Planetary Health can be a panacea for control of arboviruses. Methods A comprehensive structured search of relevant databases such as Medline, PubMed, WHO, Scopus, Science Direct, DOAJ, AJOL, and Google Scholar was conducted to identify recent articles on arboviruses and holistic approaches to health using the keywords including "arboviral diseases", "arbovirus vectors", "arboviral infections", "epidemiology of arboviruses", "holistic approaches", "One Health", "Eco-Health", and "Planetary Health".

001) in lead-exposed subjects. A predicted haplotype of the three VDR polymorphisms computed from genotyping data revealed that T-A-A haplotype increased the BLLs by 0.93 units (p ≤ 0.05) and C-C-A haplotype decreased the BLLs by 7.25 units (p ≤ 0.05). Further analysis revealed that the wild-type CC genotype of HFE H63D presented a higher median BLL, indicating that variant C allele may have a role in increasing the concentration of lead. Hence, the polymorphism of genes associated with lead metabolism might aid in predicting genetic predisposition to lead and its associated effects.Communicating in the wake of family death is complicated. Family members can vary in their expectations for support, their understandings of appropriate topics, and their approaches to coping. Using data collected from 172 individuals who experienced a family death in the last five years, this study explored family communication about loss with an eye toward identifying connections between specific communicative moments and reports of grief and adjustment. Framed within the theory of memorable messages (ToMM), five distinct memorable message types were identified and findings revealed that the type of message a bereaved individual received had direct implications for their reported amount of grief and adjustment. Messages centered on justifying or explaining the death were linked to greater grief, as compared to those that offered advice, shared a memory, or provided a sense of availability. Moderation analyses revealed that attendance to religious service impacted the relationship between message type and reports of grief and adjustment, particularly for rationale-based messages, which were more positively received by participants who attended religious service regularly. https://www.selleckchem.com/products/2-6-dihydroxypurine.html This piece supports the ToMM and extends knowledge of family communication about death, ultimately providing solace to those struggling to find the appropriate words to say to a grieving loved one.Exogenous and endogenous formaldehyde (FA) both play an important role in cell growth and migration; however, their potential role in osteoblasts remains largely unclear. Cell counting kit-8 (CCK-8) and wound-healing assays revealed that FA exposure at naturally occurring concentrations inhibited the proliferation and migration of mouse preosteoblast MC3T3-E1 cells. Moreover, RNA sequencing (RNA-seq) analysis revealed that FoxO1 signaling pathway components displayed distinct expression patterns upon FA exposure, reflected through significant enrichment of cell migration. In particular, FoxO1-, Sirt1-, and FA-induced protein expression, which was closely associated with cell proliferation and migration, was confirmed by western blotting. The results obtained indicated that the FoxO1 pathway is involved in FA-induced inhibition of cell growth and migration.
To evaluate the effect of chronicity on the size of the ostium after external dacryocystorhinostomy (DCR) with intubation.

Design A retrospective chart review of patients who underwent external DCR with intubation over 10 years from January 2003 at a tertiary hospital. All patients were recruited and examined with rigid nasal endoscope.

A total number of 66 (85 eyes) patients were included. The mean age at the time of evaluation was 53.1 years with gender distribution of 54 females (81.8 %). The mean duration ±SD between the date of surgery and the date of evaluation was 33.2 ± 33.6 (6-118 months). Our study showed an overall anatomical and functional success of 98.8% and 95.3%, respectively. The mean size of the ostium (±SD) was 23.0 (±15.7) mm
(ranging from 1 to 80.4 mm
). The size of the ostium was not a significant factor for failure (
 = 0.907). No statistically significant correlation was found between the long-term duration after surgery and the size of the ostium (
0.025,
 = 0.157).

Nasal endoscopy after DCR is valuable in evaluating the ostium with no observed potential correlation between the long-term follow-up after surgery and the size of the ostium.
Nasal endoscopy after DCR is valuable in evaluating the ostium with no observed potential correlation between the long-term follow-up after surgery and the size of the ostium.It is commonplace for science leaders and others to claim that the future of biomedical research rests in large part upon the public's trust. If true, it behooves the biomedical research community to understand how it avoids taking chances with that trust. This commentary, which builds upon comments of noted trust scholar Russell Hardin about how best to enjoy trust, assumes that the key to being trusted is deserving to be trusted. Thus, it proposes using "deserved trust" to identify ways that the public's trust in biomedical research could be better supported. Employing deserved trust to support the public's trust leads us to consider what it is that the biomedical research community should be trusted to do, examine the evidence about the effectiveness of current safeguards meant to assure that those things routinely get done, and identify new ways to equip individual researchers, research teams, and research institutions to assure that the public's trust in their research is deserved rather than misplaced.
To evaluate the anatomic and visual outcomes of a new intraocular mitomycin c (MMC) application technique in the treatment of severe traumatic retinal detachment (RD) with advance proliferative vitreoretinopathy (PVR).

The records of 15 eyes of 14 patients who underwent vitreoretinal surgery and intraoperative MMC application were reviewed retrospectively.

After performing complicated vitreoretinal surgical procedures (Pars plana vitrectomy, PVR membrane stripping, large retinotomy/retinectomies and intraocular foreign body removal if found etc. . .) retina was attached with perfluorocarbon liquid (PFCL) and partial fluid-air exchange. Endolaser was performed. PFCL was removed to the posterior borders of retinochoroidal wounds, breaks or retinectomy sites. The remaining PFCL was enough to cover and prevent MMC contact with the posterior vital structures including optic disc, macula and underlying RPE and major vascular arcades. Ciliary epithelium and other anterior segment structures were protected from was logMAR 2.16 ± 0.15 and postoperative visual acuity was 0.80 ± 0.50 (
 = 0.001). There were no additional complications related to intraoperative MMC use during follow-up period.

Temporary intraocular MMC use in vitreoretinal surgery yielded good anatomic and visual outcomes after the treatment of traumatic RDs with PVR or those with high risk of PVR development. Furthermore, MMC application appeared to prevent further PVR development after vitreoretinal surgery.

They provide water of high quality and eliminate a large amount of microorganisms, organic matter and micropollutants. However, the main limitation of membrane nanofiltration is fouling, which imposes an additional cost. This study focused on the search for microorganisms capable of reducing the performance of nanofilters and also to study autoaggregation and biofilms formation by bacterial strains isolated from the nanomembranes used in the seawater desalination plant of Souk Tlata (Algeria). It provides new microbiological data on the desalination of seawater in the southern Mediterranean basin. The results revealed 14 bacterial species isolated from six fouled reverse osmosis membranes; their quantities were significant with the dominance of Raoultella sp., Klebsiella sp., Staphylococcus sp., Stenotrophomonas sp., Micrococcus sp., and Escherichia coli. In addition, electron imaging of nanomembrane surfaces revealed complex structures of microorganisms forming biofilms.
To evaluate effectiveness of positive expiratory pressure blow-bottle device compared to expiratory positive airway pressure and conventional physiotherapy on pulmonary function in postoperative cardiac surgery patients in intensive care unit.

A randomized controlled trial.

Tertiary care.

48 patients (16 in each group; aged 64.5 ± 9.1 years, 38 male) submitted to cardiac surgery.

Patients were randomized into conventional physiotherapy (G1), positive expiratory pressure blow-bottle device (G2) or expiratory positive airway pressure, both associated with conventional physiotherapy (G3). G2 and G3 performed three sets of 10 repetitions in each session for each technique.

Pulmonary function (primary); respiratory muscle strength, radiological changes, pulmonary complications, length of intensive care unit and hospital stay (secondary) assessed preoperatively and on the 3rd postoperative day.

Pulmonary function (except for forced expiratory volume in one second/ forced vital capacity % predicted) and respiratory muscle strength showed significant reduction from the preoperative to the 3rd postoperative in all groups (
 < 0.001), with no difference between groups (
 > 0.05). Regarding radiological changes, length of intensive care unit stay and length of hospital stay, there was no significant difference between groups (
 > 0.05).

Both positive expiratory pressure techniques associated with conventional physiotherapy were similar, but there was no difference regarding the use of positive expiratory pressure compared to conventional physiotherapy.

To determine the clinical results of custom-made foot orthoses versus placebo flat cushioning insoles combined with an extracorporeal shock wave therapy on pain and foot functionality in patients with plantar fasciitis.

A randomised controlled clinical trial with follow-up at six months. Faculty of Podiatry and Centre Clinical private of Physiotherapy, Seville, Spain.

Patients with plantar fasciitis were randomly assigned to either group A (
 = 42), which received custom-made foot orthoses, or group B (
 = 41), which received placebo insoles. All the participants received active extracorporeal shock wave therapy including stretching exercises. Recruitment period was from Mach 2019 to July 2020.

The main outcome was foot pain, measured by visual analogue scale and the secondary outcome measures were recorded by Roles and Maudsley scores respectively, at the beginning and at one week, one month and six months.

Eighty-eight patients were assessed for eligibility. Eighty-three patients were recruited and randomised. This study showed significant differences between both groups according to the visual analogue scale. In control group, the difference was at baseline (
0.01) and, in the experimental group was at the one- and six-month follow-up (
0.001). The mean (SD) visual analogue scale at baseline were Control group 6.31 (1.69) and Experimental group 5.27 (1.64); and at six months were 7.52 (3.40) and 3.29 (4.26), respectively. The custom-made foot orthosis was perceived as 'good' (85%) and 'excellent' (97.5%) at medium-long term.

Wearing a custom-made foot orthosis leads to a improvement in patients with plantar fasciitis; it reduced foot pain and improved foot functionality.
Wearing a custom-made foot orthosis leads to a improvement in patients with plantar fasciitis; it reduced foot pain and improved foot functionality.

With lack of sufficient studies addressing the role of boost radiation, individualised treatment decisions are recommended, taking into account the risk factors for LR, including tumour biology. Real-life data are sorely needed to better assess the role of tumour bed boost in the contemporary era.Over the years, the management of early breast cancer has evolved by leaps and bounds, as has the concept of axillary staging and armpit surgical management. Five randomised studies exist that evaluate the possibility of omitting regional locus surgical axillary treatment in patients with early breast cancer and positive sentinel lymph nodes without it having an impact on the prognosis of the disease in selected cases. A review of the literature on the management of the axilla in early breast cancer is presented.
Breast cancer is the most common cancer among women in both developed and developing nations. The survival of breast cancer is increasing in developed countries with improved treatment modalities, while still very poor in developing countries. In Nigeria, few breast cancer survival data are available.

This is a retrospective cross-sectional study.

To determine the survival of breast cancer patients and possible factors influencing it.

Socio-demographic and clinical variables from treatment records and case notes of breast cancer patients treated from 1 January 2004 to 31 December 2008 at the Department of Radiation Oncology, University College Hospital, Ibadan. The status of patients was determined at 2 and 5 years after diagnosis. The survival of patients with breast cancer was compared using Log Rank test according to socio-demographic and clinical variables. The median survival times were obtained from the Kaplan-Meier survival curve. Cox's proportional hazard model was fitted for those that were sease-free survival at 2 and 5 years was 66.6% and 60.3%, respectively. Median time for recurrence was 8.0 months. Level of education, height, tumour unilaterality, clinical tumour size, stage at presentation, presence of distant metastases, clinical axillary lymph node metastasis, supraclavicular node metastasis, mode of surgery and axillary clearance were found to have statistically significant association with survival.

A large number of the patients in our study presented at a young age, late with advanced stage disease which results in poor survival outcome.

Epidemiological studies have shown conflicting results regarding air pollution and breast cancer risk, which could be explained by the multitude of other risk factors that could affect the association. In Chile, air pollution has reached alarming levels, either due to motorised vehicle traffic or the combustion of wood for heating; therefore, our objective was to evaluate the association between the incidence of breast cancer and the concentration of the main air pollutants monitored in the country. We carried out a cross-sectional ecological study that evaluated the association between the average incidence of breast cancer in years (2016 to 2018) and the average annual concentration of six atmospheric pollutants in the 5 years prior to the estimation of the rate in communes of Chile, using the population of beneficiaries of Instituto Oncológico Fundación Arturo López Pérez. The annual incidence of breast cancer was 72.21 cases per 100,000 women and it varied significantly in the communes studied compared to the human development index (HDI) and to the proportion of women in the age group at highest risk. Assessing the relationship between the incidence of breast cancer and the average concentration of atmospheric pollutants, we only found a direct correlation between the level of nitrogen dioxide and the rate (R = 0.82; p = 0.044), whose significance tends to be lost when age and the communal HDI are included in a regression model.
Diagnosis and treatment of cancer rely heavily on imaging, histopathology and molecular information. Incomplete or missing tumour information can hinder the delivery of high-quality care in oncology practice, especially in resource-limited countries. To evaluate the completeness of histopathology reporting in a real-world setting and identify areas for future cancer care delivery research efforts, we retrospectively analysed reports from patients diagnosed with breast cancer who received care at a high-volume oncology department at a hospital in Lagos, Nigeria.

Demographic, institutional and histopathology characteristics were retrospectively obtained from 1,001 patient records from 2007 to 2016. https://www.selleckchem.com/products/pik-iii.html Completeness was defined as reporting five tumour features (tumour histology, tumour grade, laterality, oestrogen receptor (ER) or progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2)) for biopsy specimens and seven tumour features (tumour size, tumour histology, tumour grade, lateralityast cancer histopathological characteristics commonly used in oncology practice. Our study highlights a need to identify and address the contributing factors for incomplete histopathological reporting in Nigeria and will guide future clinical programmatic developments.
The coronavirus disease 2019 (COVID-19) pandemic presents serious challenges to cancer care because of the associated risks from the infection itself and the disruption of care delivery. Therefore, many professional societies have published recommendations to help manage patients with cancer during the current pandemic. The objective of our study is to assess the national responses of Middle East North Africa (MENA) countries in terms of publishing relevant guidelines and analyse various components of these guidelines.

A survey based on the preliminary review of the literature regarding cancer care adaptations has been developed and then completed by a group of oncologists from the following Arab countries affected by the pandemic Algeria, Egypt, Iraq, Jordan, Kuwait, Lebanon, Morocco, Oman, Saudi Arabia, Syria, Tunisia, United Arab Emirates and Yemen. The survey inquired about COVID-19 cases, national recommendations regarding general measures of COVID-19 prevention and patient care in oncology as well arab Middle East and North Africa region surveyed. However, there are inconsistencies in the various components of the guidelines across the region, which reflects the evolving status of the pandemic in each country as well as the lack of clear evidence-based guidelines for many of the issues in question. There is a need for a clear framework on essential components that should be included in these guidelines to assure providing the best guidance to the oncology community.More effective treatments for people with psychotic disorders are urgently required. Here, we make three suggestions for progress 1. Targeting the disorders' core phenomenological features ('phenomenological phenotype'), 2. Addressing social disconnection, isolation and loneliness, and 3. Leveraging 'hot' cognitions and using symptom capture approaches that combine psychotherapy with advances in technology and neuroscience.Infantile haemangiomas (IHs) are relatively common benign vascular tumours found in the paediatric population. They have varying sizes and involve different depths in the skin leading to various colours, shapes and textures. Although considered harmless in most cases, they may lead to life-threatening complications or cause permanent disfigurations and organ dysfunction. For problematic IHs, the treatment options include oral and topical beta-blockers, systemic corticosteroids, laser treatment, and surgery. In this narrative review, the treatment options for problematic IH are compared and delivered concisely to facilitate the clinical decisions from practitioners, including those in primary care settings. Oral propranolol is currently considered the first-line intervention for problematic IHs. For superficial lesions, there is robust evidence for the use of topical timolol maleate. Systemic corticosteroids are sometimes used in specific situations such as resistance or contraindications to beta-blockers. Surgical excision can be considered in cases requiring urgent intervention such as airway obstruction; this can be done alongside laser therapies for the removal of residual tissue or when reconstructing areas of deformity. The combination of multiple treatment modalities may lead to a more rapid clinical response.
Atopic dermatitis (AD) is one of the most common chronic inflammatory skin diseases worldwide. AD pathogenesis is multifactorial, involving environmental and genetic factors. IL-13 stands out as one of the main cytokines in the pathophysiology of AD. Currently, dupilumab, which targets both IL-4 and IL-13 signalling, is the only biologic agent approved for the treatment of moderate-to-severe AD. New targeted biologic therapies are being developed, such as lebrikizumab and tralokinumab, two selective IL-13 inhibitors. This article reviews the role of IL-13 in AD and the most recent data on lebrikizumab and tralokinumab.

A narrative review of the literature was written after retrieving relevant articles in the PubMed database (up until December 2020) using the following keywords present in the title, abstract or body atopic dermatitis; interleukin 13; IL-13; tralokinumab; lebrikizumab, biologic therapy.

A phase IIb trial showed that all three dosing regimens evaluated (lebrikizumab 125 mg every 4 weeks (Qerefore, the development of lebrikizumab and tralokinumab represents a new and exciting phase in the management of AD.
A textiloma is a rare retained surgical swab with probable serious post-operation complications.

Here, we reported an asymptomatic patient who had past history of coronary artery bypass grafting (CABG) fourteen months ago and referred to our institute for left atrial mass removal. Echocardiography and chest computed tomography (CT) scan revealed a non-homogenous non-mobile mass and a heterogeneous lesion with low-density as well as high-density areas with spot calcification and gas bubbles at left atrium level, respectively.

Despite being rare after CABG, textiloma should be considered in the differential diagnosis in case of any suspicious chest mass even in asymptomatic patients.

Cardiovascular disease (CVD) includes a group of heart and coronary disorders that can be prevented by promoting the quality of an individual's diet. The Recommended Food Score (RFS) and Healthy Nordic Food Index (HNFI) are suggested for the assessment of diet quality and as indicators of dietary exposures related to disease. The aim of this study was to systematically review the association of the RFS and the HNFI with CVD and stroke.

Articles were identified by searching PubMed, Google Scholar, and ScienceDirect using relevant keywords for articles published until December 2018. The inclusion criteria were all types of observational studies and English language. Non-English and irrelevant studies were excluded.

In total, 14 studies met the inclusion criteria. Of the 7 studies that investigated the association between the RFS and CVD, 6 articles showed a lower risk of CVD in individuals who obtained a higher RFS and lower non-RFS (n-RFS) score. Studies that investigated the relation between RFS and stroke (n = 2) showed that achieving a higher RFS could decrease the risk of stroke.
