2-22.5), 8.6% (95% CI 6.6-11.1), and 1.3% (95% CI 0.7-2.5), respectively. Moreover, females have shown a higher prevalence of any DR, compromising 60.2% of all patients diagnosed with DR, 62.3% of all NPDR patients, and 75.0% of all PDR patients. https://www.selleckchem.com/products/asunaprevir.html However, there was no significant association between sex and DR (
0.840). There was a significant association between having DM for 10 years and DR (
0.010).

The prevalence of DR increased from 14.3% in 2003 to 19.3% in 2017. Effective health policies and screening programs should be employed to control the increased prevalence of DM and DR.

To date, the quantity and the quality of research publications conducted within the Oman Medical Specialty Board (OMSB) have not been assessed. In this review, we sought to assess the quantity and quality of research publications affiliated with the OMSB.

We retrieved data systematically from PubMed, Scopus, Web of Science, and Google Scholar. We searched all publications published until December 2018.

A total of 133 published articles affiliated with the OMSB were retrieved. Half of the publications were original studies, and 30.8% were case reports or series. Reviews and editorials represented 6.8% and 8.3%, respectively. Among the original studies, 79.4% were cross sectionals and 50.0% were retrospective in nature. Among the prospective studies, 58.8% were questionnaire-based surveys. The impact factors of the journals ranged between 0.82 and 4.40, except for one journal with an impact factor of 15.10.

The quantity and quality of the publications from the OMSB is still low. However, training and policy change in the residency curriculum is key to improve the status.

Healthcare workers (HCWs), especially those working on the front line, are considered to be at high risk of nosocomial acquisition of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19). Little is known about the effectiveness of the recommended protective methods as few reports have described spread of the disease in hospital settings among this high-risk population. We describe the hospital-based transmission of SARS-CoV-2 related to non-invasive ventilation (NIV) in one of the main tertiary care hospitals in Oman.

All exposed patients and HCWs from Royal Hospital were screened, quarantined, and underwent telephone interviews to stratify their risk factors, clinical symptoms, and exposure risk assessment.

A total of 46 HCWs and patients tested positive for SARS-CoV-2 after exposure to an index case who received 48 hours of NIV before diagnosing COVID-19 infection. Over half of the exposed (56.5%; n = 26) were nurses, 26.1% (n = 12) were patients, and 15.2% (n = 7) were doctors. None of the HCWs required hospitalization. Sore throat, fever, and myalgia were the most common symptoms.

NIV poses a significant risk for SARS-CoV-2 transmission within hospital settings if appropriate infection control measures are not taken.

Prophylactic use of inferior vena cava filters to prevent pulmonary embolism in trauma is controversial. The practice varies between hospitals and countries, in part due to conflicting evidence and guidelines.

To compare the effects of pulmonary embolism, deep venous thrombosis and mortality in two hospitals using prophylactic inferior vena cava filter placement or prophylactic anticoagulation alone.

Patients presenting with severe trauma were recruited from two level-1 trauma centres between January 2008 and December 2013. Recruited patients from an US hospital having prophylactic inferior vena cava filter inserted were compared to a Scandinavian hospital using prophylactic anticoagulation alone. Inclusion criteria were age >15 years, Injury Severity Score >15 and survival >24 h after hospital admission. Patients with venous thromboembolism diagnosed prior to inferior vena cava filter placement were excluded. link2 A Cox proportional hazard regression model was used with adjustment for immortal timeas not associated with pulmonary embolism or mortality. However, inferior vena cava filters were associated with increased rate of deep venous thrombosis.Community protective immunity can affect RNA virus evolution by selecting for new antigenic variants on the scale of years, exemplified by the need of annual evaluation of influenza vaccines. The extent to which this process termed antigenic drift affects coronaviruses remains unknown. Alike the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), seasonal human coronaviruses (HCoV) likely emerged from animal reservoirs as new human pathogens in the past. We therefore analyzed the long-term evolutionary dynamics of the ubiquitous HCoV-229E and HCoV-OC43 in comparison with human influenza A virus (IAV) subtype H3N2. We focus on viral glycoprotein genes that mediate viral entry into cells and are major targets of host neutralizing antibody responses. Maximum likelihood and Bayesian phylogenies of publicly available gene datasets representing about three decades of HCoV and IAV evolution showed that all viruses had similar ladder-like tree shapes compatible with antigenic drift, supported by different tentially representing antigenic drift occurred on a lower scale in endemic HCoV compared to IAV. It seems likely that pandemic SARS-CoV-2 evolution will bear similarities with IAV evolution including accumulation of adaptive changes in the RBD, requiring vaccines to be updated regularly, whereas higher SARS-CoV-2 evolutionary stability resembling endemic HCoV can be expected in the post-pandemic stage.
There is limited information about the association between long-term leisure time physical activity (LTPA) participation and healthcare costs. The purpose of this study was to investigate the association between LTPA over adulthood with later life healthcare costs in the USA.

Using Medicare claims data (between 1999 and 2008) linked to the National Institutes of Health-American Association of Retired Persons (NIH-AARP) Diet and Health Study, we examined associations between nine trajectories of physical activity participation throughout adulthood with Medicare costs.

Compared with adults who were consistently inactive from adolescence into middle age, average annual healthcare costs were significantly lower for maintainers, adults who maintained moderate (-US$1350 (95% CI -US$2009 to -US$690) or -15.9% (95% CI -23.6% to -8.1%)) or high physical activity levels (-US$1200 (95% CI -US$1777 to -US$622) or -14.1% (95% CI -20.9% to -7.3%)) and increasers, adults who increased physical activity levels in early adulthood (-US$1874 (95% CI US$2691 to -US$1057) or -22.0% (95% CI -31.6% to -12.4%)) or in middle age (-US$824 (95% CI -US$1580 to -US$69 or -9.7% (95% CI -18.6% to -0.8%)). For the four trajectories where physical activity decreased, the only significant difference was for adults who increased physical activity levels during early adulthood with a decline in middle age (-US$861 (95% CI-US$1678 to -US$45) or -10.1% (95% CI -19.7% to -0.5%)).

Our analyses suggest the healthcare cost burden in later life could be reduced through promotion efforts supporting physical activity participation throughout adulthood.

To determine professional footballers' level of understanding of the purpose of the precompetition medical assessment (PCMA) and to evaluate their knowledge of potential outcomes following a PCMA, including disqualification.

Professional footballers from the Australasian A-League and Westfield W-League were asked to complete a 25-question survey. The relationship between dichotomised outcomes and explanatory variables was analysed with multivariate logistic regression; p<0.05 was considered statistically significant.

A total of 212 players participated (response rate=48.8%). Most respondents selected '
' and '
' (n=137, 64.6%; n=130, 61.3%) as the purpose of a PCMA. link3 Approximately one-third (n=74, 38.1%) were neutral or believed that a normal PCMA prevented cardiac arrest. Receiving more PCMAs (p<0.0003) and receiving an explanation during their PCMA (p=0.0175) led to greater awareness of the assessment's limitations. Most participants did not know the definitions of syncope (n=181, 93.3%) or Mar provide this education.
To establish pupil fitness levels, and the relationship to global norms and physical education (PE) enjoyment. To measure and describe physical activity (PA) levels during secondary school PE lessons, in the context of recommended levels, and how levels vary with activity and lesson type.

A cross-sectional design; 10 697 pupils aged 12.5 (SD 0.30) years; pupils who completed a multistage fitness test and wore accelerometers to measure PA during PE lessons. Multilevel models estimated fitness and PE activity levels, accounting for school and class-level clustering.

Cardiorespiratory fitness was higher in boys than girls (ß=-0.48; 95% CI -0.56 to -0.39, p<0.001), within absolute terms 51% of boys and 54% of girls above the 50th percentile of global norms. On average, pupils spent 23.8% of PE lessons in moderate-to-vigorous PA (MVPA), and 7.1% in vigorous PA (VPA). Fitness-focused lessons recorded most VPA in co-educational (ß=1.09; 95% CI 0.43 to 1.74) and boys-only lessons (ß=0.32; 95% CI -0.21 to 0.85). In girls-only lessons, track athletics recorded most VPA (ß=0.13; 95% CI -0.50 to 0.75) and net/wall/racket games (ß=0.97; 95% CI 0.12 to 1.82) the most MVPA. For all lesson types, field athletics was least active (ß=-0.85; 95% CI -1.33 to -0.36). There was a relationship of enjoyment of PE to fitness (ß=1.03; 95% CI 0.83 to 1.23), and this relationship did not vary with sex (ß=-0.14 to 0.23; 95% CI -0.16 to 0.60).

PE lessons were inactive compared with current guidelines. We propose that if we are to continue to develop a range of sporting skills in schools at the same time as increasing levels of fitness and PA, there is a need to introduce additional sessions of PE activity focused on increasing physical activity.

It is important to recognize this condition in patients with subacute to chronic posterior circulation vascular insufficiency as early diagnosis and treatment can have good clinical outcomes (J Clin Neurosci. 2010;171339). CT angiogram of the head and neck should be considered in patients with chronic vertebrobasilar insufficiency to evaluate subclavian steal syndrome.

In diabetic foot infections (DFIs), the diversity of microbial profile and ever-changing antibiotic-resistance patterns emphasize accurate characterization of microbial profile and antibiotic susceptibility pattern. The aim of the study was to investigate the pathogens associated with DFI and their antibiotic susceptibility patterns.

A cross-sectional retrospective study was conducted at a tertiary-care hospital, Oman. The socio-demographic and microbiological profile and antibiotic susceptibility patterns of pathogens isolated from patients with DFIs from January 2013 to December 2018 were reviewed. Quantitative and qualitative variables were expressed as mean ± standard deviation and percentages, respectively. A Chi-square test was used for testing the association between multidrug-resistant (MDR) organisms and variables.

In total, 233 isolates recovered from 133 clinical specimens with an average of 1.8 organisms per specimen were included in the study. Fifty-six and forty-four percent of specimens smpirical therapy of Gram-negative and Gram-positive bacterial DFIs, respectively.
Any prediction of a person's ability to succeed in a motor skill depends on the detection and accurate measurement of the basic abilities for the performance of that skill. Task analysis is needed to determine the psychomotor skills and abilities required to perform an action. This study aimed to determine the components of psychomotor abilities for diagnostic upper gastrointestinal (GI) endoscopy through procedural task analysis (PTA) and expert review.

A multisource, multimethod task analysis was conducted in six metropolitan teaching hospitals affiliated with the adult gastroenterology and hepatology training centers in the Islamic Republic of Iran in 2019. Observation, video-recording, and think-aloud protocols were used while diagnostic upper GI endoscopy was performed. To confirm the accuracy of the PTA, the incorporated the views of the adult gastroenterology and hepatology subspecialty experts through the checklist of PTA assessment criteria. Finally, to determine the psychomotor abilities for eacortional tests are developed.
One of the influential factors in students' learning is their learning styles which have the capacity to change. Furthermore, creativity is considered one of the essential cognitive features of humans. Thus, this study aimed to analyze the relationship between learning styles (Kolb and VARK) and emotional creativity with the academic achievement of dental students.

In this descriptive-analytical study, the statistical population included dental students of the third semester and above (250 persons). The data collection tools included Kolb and VARK learning style questionnaires, Averill emotional creativity questionnaire, the total Grade Point Average (GPA), and the GPA over the past two semesters of students to measure academic achievement. The data were analyzed using the measures of the descriptive (mean and standard deviation) and the inferential statistics tests including one-sample
-test, independent
-test, correlation coefficients of Pearson, and Eta squared.

Based on Kolb and VARK learning ste learning styles were more prevalent among students and they showed high emotional creativity.
Smokeless tobacco use is a public health problem. This study explored students' beliefs about smokeless tobacco use in Chabahar, Iran.

The qualitative study was conducted using three Focused Group Discussions among 24 students aged 12-14 years in Chabahar City. Focus Group Guide Morgan was used. https://www.selleckchem.com/products/gdc-0068.html Qualitative Content Analysis was used to explore and extract codes and themes. The data analysis process was carried out in accordance with the stages of proposed by Graneheim and Lundman. Guba and Lincoln criteria were used for evaluating research transferability.

Two main themes emerged from the analysis including; beliefs of being useful and harmful. Each of these themes is divided into subthemes with useful or harmful physical and psychological beliefs. Four subthemes included beliefs of being useful physically, beliefs of being useful psychologically, harmful beliefs physically, and harmful beliefs psychologically.

One of the more significant findings to emerge from this study is that many students mentioned the benefits of using smokeless tobacco to reduce toothache, relieve headaches, and bad breath. This information can be used to develop targeted interventions aimed at reducing smokeless tobacco consumption. However, more research on this topic needs to be undertaken before the association between kinds of beliefs and smokeless tobacco consumption is more clearly understood.

With growing resident burnout, Accreditation Council for Graduate Medical Education issued new requirements for program interventions to optimize resident well-being. Little evidence exists on how to best teach resiliency to residents. This study assesses the impact of both a grassroots intervention and formal resiliency curriculum on resident burnout and well-being.

From November 2016 to August 2017, residents in a large Internal Medicine Residency Program participated in grassroots wellness interventions from the resident-led Gator Council in Gainesville, FL USA. From August 2017 to June 2018, residents participated in a formal program-driven resiliency curriculum. Wellness interventions included monthly morning reports, bimonthly workshops, and biannual noon conferences. Pre- and postintervention Maslach Burnout Inventory (MBI) and Physician Well-Being Index (PWBI) assessed the effect of both interventions on resident burnout and well-being. Statistical analyses used Student's
-test, Fisher's exact tt.
This study found no improvement in resident burnout or well-being from a bottom-up and top-down approach. Our results imply the need for an early wellness curriculum to improve student well-being given their higher level of burnout. System-wide efforts are vital to combat physician burnout.
Individuals with disordered eating are at an increased of having one or more additional risks for comorbid disorders, such as anxiety disorder, depressive disorder, and insomnia. Therefore, the present study aimed to investigate the mediating role of self-compassion in the relationship between positive reactivity, negative reactivity, and perfectionism with disordered eating.

The study method was descriptive-correlational through structural equation modeling (SEM). The present study population included all students of the University of Tehran in the city of Tehran in 2018-2019. A total of 302 students were selected by convenience sampling method and completed questionnaires on eating attitudes test-8, self-compassion scale (short form), eating disorder inventory-perfectionism scale, and Perth emotional reactivity scale. The SEM path analysis and Pearson correlation coefficient were conducted to analyze the obtained data in SPSS-23 and Lisrel-8.80.

The finding of the path analysis showed that self-compassion acts as a mediating role in the relationship of disordered eating with positive and negative emotional reactivity and perfectionism. Only the direct effect coefficient of general positive reactivity on disordered eating was not significant.

Based on the results of this study, self-compassion can serve as a protective factor against negative emotional reactivity and perfectionism. Therefore, self-compassion can be considered in the development of prevention and treatment programs for disordered eating.

The knowledge level of caregivers and their support for patients can affect the self-care of patients with heart failure (HF). The present study was conducted to compare the effects of teach-back, multimedia, and blended training methods on self-care and social support in patients with HF and on knowledge in their caregivers.

In a randomized clinical trial, a total of 150 HF patient-caregiver dyads were randomly allocated into three equally sized training groups, using a simple number table (
= 50). The study was conducted between May to October 2018 in Sari, northern Iran. In the teach-back, multimedia and blended training groups, patient-caregiver dyads participated in 20-30-min training sessions held face-to-face, using digital video disc (DVD) and combination of teach-back and DVD on 4 consecutive days at the bedside of hospitalized patients in coronary care unit, respectively. Data were collected using the European Heart Failure Self-Care Behaviour Scale and the multidimensional scale of perceived s that all three educational interventions can improve self-care behaviors in HF patients and increase knowledge in their caregivers. However, using the blended training method was associated with better outcomes.
According to the results of the present study, it seems that all three educational interventions can improve self-care behaviors in HF patients and increase knowledge in their caregivers. However, using the blended training method was associated with better outcomes.
Management of cancer complications requires the provision of palliative care as a comprehensive care by the main and trained members of this method of care. The aim of the present study was to assess the compliance of educational curricula of selected disciplines with the content standards of cancer-related palliative care.

In this descriptive-comparative study, the content standards of palliative care for nurses, physicians, and social workers were identified based on the World Health Organization guideline and Oxford Textbook of Palliative Nursing. For this purpose, a separate checklist was prepared for the disciplines with different dimensions. Then the face and content validity of the checklists were checked. Finally, we examined the coordination between selected curricula available on the website of Education Deputy of the Ministry of Health, Treatment and Medical Education with the dimensions of the checklists.

All three curricula in most domains were relevant with the content standards, but there was the biggest education need in the areas related to the dimensions of "planning and educational," "educating physician in palliative care," and "considering patient preferences" in these disciplines.

Incidence of malaria and anaemia are of public health importance especially in pregnant women in endemic regions, due to the negative health consequences to the mother and fetus. This study aimed to assess the pattern of falciparum malaria infection and anaemia, based on malaria prevention methods practiced by participants.

A semi-structured tool was used to capture information on demographic, socio-economic and malaria prevention practices from 113 pregnant women attending antenatal clinics in 2 peri-urban health facilities in Lagos, southwest Nigeria. Malaria microscopy was conducted and haematocrit was measured. Logistic regression analysis was performed on the data collated from the survey.

The prevalence of anaemia among pregnant women was 87.2%. The mean (± sd) packed cell volume (PCV) (%) of the 22 (19.5%) infected subjects (26.8 ± 6.6), was significantly lower (t = -2.60, P value = 0.007) than that of the 91 (80.5%) uninfected subjects (30.8 ± 6.0). The prevalence of infection was highest in theticide-treated bed nets (LLIN), IPT and the dangers of herbal teas in pregnancy.
Interventions that will reduce malaria and moderate to severe anaemia, especially in a first pregnancy, should include education on the correct use of long-lasting insecticide-treated bed nets (LLIN), IPT and the dangers of herbal teas in pregnancy.Human vagina is colonised by a diverse array of microorganisms that make up the normal microbiota and mycobiota. Lactobacillus is the most frequently isolated microorganism from the healthy human vagina, this includes Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus iners, and Lactobacillus jensenii. These vaginal lactobacilli have been touted to prevent invasion of pathogens by keeping their population in check. However, the disruption of vaginal ecosystem contributes to the overgrowth of pathogens which causes complicated vaginal infections such as bacterial vaginosis (BV), sexually transmitted infections (STIs), and vulvovaginal candidiasis (VVC). Predisposing factors such as menses, pregnancy, sexual practice, uncontrolled usage of antibiotics, and vaginal douching can alter the microbial community. Therefore, the composition of vaginal microbiota serves an important role in determining vagina health. Owing to their Generally Recognised as Safe (GRAS) status, lactobacilli have been widely utilised as one of the alternatives besides conventional antimicrobial treatment against vaginal pathogens for the prevention of chronic vaginitis and the restoration of vaginal ecosystem. In addition, the effectiveness of Lactobacillus as prophylaxis has also been well-founded in long-term administration. This review aimed to highlight the beneficial effects of lactobacilli derivatives (i.e. surface-active molecules) with anti-biofilm, antioxidant, pathogen-inhibition, and immunomodulation activities in developing remedies for vaginal infections. We also discuss the current challenges in the implementation of the use of lactobacilli derivatives in promotion of human health. In the current review, we intend to provide insights for the development of lactobacilli derivatives as a complementary or alternative medicine to conventional probiotic therapy in vaginal health.
The absence of ability and certainty to design and undertake pharmacy practice-based research (PPBR) was a major issue among pharmacists worldwide as reported in previous literature, despite them having an interest in conducting PPBR. Therefore, this study aimed at highlighting the research background of the Gulf Cooperation Council (GCC) pharmacists which are the six Arab states of the Arabian Gulf, and examining barriers to conducting PPBR. In addition, to determine the self-perceived level of competence and confidence when planning and conducting PPBR.

This is a descriptive, cross-sectional questionnaire-based study, performed among pharmacists working in the GCC countries (i.e. Saudi Arabia, United Arab Emirates, Kuwait, Bahrain, Oman and Qatar). A pre-validated questionnaire was distributed to a convenience sample, via distribution of 500 research participation cards to conference attendees. These cards a quick response (QR) code, which should be scanned via mobile phone, to direct all readers to the overall ability to conduct PPBR. In addition, they had more interest in conducting PPBR (MWU = 3061.500, z = - 4.126, p = 0.000) and in learning about how to do so (MWU = 8698, z = - 1.898, p = 0.050).

Pharmacists practicing in the GCC geographic area realized the importance of planning and conducting PPBR and were more confident and competent to undertake and contribute to PPBR, except for skills related to statistical analysis. Therefore, training programmes especially for biostatistics and data analysis are mandatory to enhance pharmacists' research capabilities.

Carpal tunnel syndrome is a common peripheral nerve compression disorder. https://www.selleckchem.com/products/piceatannol.html However, there is no established opinion regarding the predictors of symptom improvement after surgery. This study aimed to identify the predictors of surgical outcomes of severe carpal tunnel syndrome patients.

In the patients who underwent a carpal tunnel syndrome surgery, we selected the patients who had a preoperative Bland's classification of grade 5 or 6, and assessed for the changes in Bland's classification grade before and after surgery. Those who showed improvement from preoperative grades 5-6 to postoperative grades 1-4 comprised the improvement group. In contrast, those who did not show improvement and had postoperative grades 5 or 6 comprised the non-improvement group. In a nerve conduction study, amplitudes of the compound muscle action potential and sensory nerve action potential of the palms were assessed between the improvement and non-improvement groups.

Among the 60 hands of 46 patients who had a preoperative Bland's classification of grade 5 or 6, 49 hands of 37 patients comprised the improvement group, and 11 hands of 9 patients comprised the non-improvement group.

Hookworm and Schistosoma mansoni infections and anemia are highly prevalent among schoolchildren. Hookworm and Schistosoma mansoni infections are significantly associated with anemia. Therefore, helminthic detection and hemoglobin determination should be done simultaneously among schoolchildren.
The relationship between circulating effector memory T and B cells long after transplantation and their susceptibility to immunosuppression are unknown. To investigate the impact of antirejection therapy on T cell-B cell coordinated immune responses, we assessed IFN-
-producing memory cells and natural antibodies (nAbs) that potentially bind to autoantigens on the graft.

Plasma levels of IgG nAbs to malondialdehyde (MDA) were measured in 145 kidney transplant recipients at 5-7 years after transplantation. In 54 of these patients, the number of donor-reactive IFN-
-producing cells was determined. 35/145 patients experienced rejection, 18 of which occurred within 1 year after transplantation.

The number of donor-reactive IFN-
-producing cells and the levels of nAbs were comparable between rejectors and nonrejectors. The nAbs levels were positively correlated with the number of donor-reactive IFN-
-producing cells (

 = 0.39,
=0.004). The positive correlation was only observed in rejectors (

 = 0.53,
=0.003; nonrejectors

 = 0.24,
=0.23). Moreover, we observed that intravenous immune globulin treatment affected the level of nAbs and this effect was found in patients who experienced a late ca-ABMR compared to nonrejectors (
=0.008).

The positive correlation found between alloreactive T cells and nAbs in rejectors suggests an intricate role for both components of the immune response in the rejection process. Treatment with intravenous immune globulin impacted nAbs.

We aimed to further investigate the role of breastfeeding in the severity of nonhereditary RB development, assessing relationship to (1) age at diagnosis, (2) ocular prognosis, measured by International Intraocular RB Classification (IIRC) or Intraocular Classification of RB (ICRB) group and success of eye salvage, and (3) extraocular involvement. Analyses were performed on a global dataset subgroup of 344 RB patients whose legal guardian(s) consented to answer a neonatal questionnaire. Patients with undetermined or mixed feeding history, family history of RB, or sporadic bilateral RB were excluded. https://www.selleckchem.com/products/gdc-0068.html There was no statistically significant difference between breastfed and formula-fed groups in (1) age at diagnosis (p = 0.20), (2) ocular prognosis measures of IIRC/ICRB group (p = 0.62) and success of eye salvage (p = 0.16), or (3) extraocular involvement shown by International Retinoblastoma Staging System (IRSS) at presentation (p = 0.74), lymph node involvement (p = 0.20), and distant metastases (p = 0.37). This study suggests that breastfeeding neither impacts the sporadic development nor is associated with a decrease in the severity of nonhereditary RB as measured by age at diagnosis, stage of disease, ocular prognosis, and extraocular spread. A further exploration into the impact of diet on children who develop RB is warranted.The novel coronavirus disease 2019 (COVID-19) pandemic has caused significant morbidity and mortality worldwide. The most common symptoms include fever, cough, and shortness of breath (predominantly involving pulmonary function). However, there are lesser-known presentations that affect other systems too. Vascular complications have been reported in the literature focusing on venous thrombosis, which appears to be more common than arterial thrombosis. Among arterial thrombosis, mainly lower limb involvement is reported so far. Here, we report an unusual presentation in COVID-19, which presented with acute abdomen due to superior mesenteric artery thrombosis without respiratory symptoms. We report this case as a varied form of coronavirus complication presentation and highlight the need for eternal vigilance and a reactive approach for early diagnosis.The Coronavirus disease-2019 (COVID-19) outbreak was classified as a global pandemic by the World Health Organization on 11 March 2020. It is caused by the novel severe acute respiratory syndrome coronavirus 2. The virus affects mainly the human respiratory system. Mycobacterium tuberculosis (TB) is another respiratory infection known to affect humans and may share joint clinical presentations and risk factors with COVID-19 infection. Therefore, clinicians must have a high index of suspicion that the two infections might coexist so that there is no delay in diagnosis and starting the appropriate treatment. There are few case reports about TB and COVID-19 coinfection. The first case report ever was from China and there have been a few others around the world. Here, we report two cases of coexisting COVID-19 and newly diagnosed pulmonary TB infection in Oman.
Considering the increasing, significant burden that coronavirus disease 2019 (COVID-19) imposes on the healthcare system, the need for simple, rapid, and affordable diagnostic tests to support the existing costly and demanding polymerase chain reaction (PCR) assay becomes required. This prospective diagnostic test accuracy study aims to evaluate the performance of four different COVID-19 rapid antigen tests compared to real-time reverse transcription PCR (rRT-PCR) between June and July 2020 to determine the feasibility of integrating these tests into the diagnostic algorithm in clinical settings.

Swabs were collected from 306 patients and analyzed using rRT-PCR and antigen tests from four different providers.

The antigen tests' sensitivities were 65.8%, 69.8%, 64.0%, and 64.3% for the STANDARD™ Q COVID-19 Ag test, PCL COVID-19 Ag Rapid fluorescent immunoassay (FIA) test, BIOCREDIT COVID-19 Ag test, and Sofia SARS-CoV-2 antigen FIA test, respectively. Specificity was 94.1% for PCL COVID-19 Ag Rapid test s. Given the low sensitivity of 64.0-69.8% of the antigen tests, we recommend that clinically relevant negative results undergo further testing Ag to confirm or exclude a COVID-19 diagnosis.
The novel severe acute respiratory syndrome coronavirus 2 pandemic continues to spread globally without an effective treatment. In search of the cure, convalescent plasma (CP) containing protective antibodies from survivors of coronavirus disease 2019 (COVID-19) infection has shown potential benefit in a non-intensive care unit setting. We sought to evaluate the effectiveness of CP therapy for patients with COVID-19 on mechanical ventilation (MV) and/or acute respiratory distress syndrome (ARDS).

We conducted an open-label trial in a single center, Royal Hospital, in Oman. The study was conducted from 17 April to 20 June 2020. The trial included 94 participants with laboratory-confirmed COVID-19. The primary outcomes included extubation rates, discharges from the hospital and overall mortality, while secondary outcomes were the length of stay and improvement in respiratory and laboratory parameters. Analyses were performed using univariate statistics.

The overall mean age of the cohort was 50.0±15.0 years, and 90.4% (n = 85) were males. A total of 77.7% (n = 73) of patients received CP. Those on CP were associated with a higher extubation rate (35.6% vs. 76.2%;
< 0.001), higher extubation/home discharges rate (64.4% vs. 23.8%;
0.001), and tendency towards lower overall mortality (19.2% vs. 28.6%;
0.354; study power = 11.0%) when compared to COVID-19 patients that did not receive CP.

CP was associated with higher extubation/home discharges and a tendency towards lower overall mortality when compared to those that did not receive CP in COVID-19 patients on MV or in those with ARDS. Further studies are warranted to corroborate our findings.

Oxidation of the obtained alcohol into ketone followed by condensation with 4-sulfamidophenylhydrazine afforded the targeted drug with full regioselectivity. It is noteworthy that the quality of these flow reactions (50% overall yield within 1 h cumulated residence time over 3 steps) directly furnished the target API and intermediates with excellent purity.

The mechanistic basis for this phenomenon remains poorly understood so far, although epigenetic mechanisms such as DNA methylation, histone modifications and microRNA-mediated gene regulation apparently play a crucial role. The key role of epigenetic modifications triggered by unfavorable environmental cues during sensitive developmental periods in linking adverse early-life events to later-life health outcomes is evident from a large body of studies, including methylome-wide association studies and research of candidate genes. Toxic metals (TMs), such as heavy metals, including lead, chromium, cadmium, arsenic, mercury, etc., are among environmental contaminants currently most significantly impacting human health status. Since TMs can cross the placental barrier and accumulate in fetal tissues, exposure to high doses of these xenobiotics early in development is considered to be among important factors contributing to the developmental programming of adult-life diseases in modern societies. In this mini-review, we summarize epidemiological findings indicating that prenatal TM exposure can induce epigenetic dysregulation, thereby potentially affecting adult health outcomes.[This corrects the article DOI 10.1093/eep/dvw018.].
Lung transplantation (LT) requires complex multidisciplinary organization and constitutes a therapeutic option and a life-saving procedure. Although the number of lung recipients continues to increase, neurological complications and death rates following lung transplantation are still higher than desirable.

This study aims to analyse the neuroimaging findings in a cohort of adult patients with LT.

A retrospective cohort study of all lung transplant recipients (344 patients 205 men and 139 women) at a single institution from January 2011 to January 2020. The collected data included demographic features, clinical data and evaluation of the imaging findings. We also recorded the date of neurological complication(s) and the underlying disease motivating lung transplantation.

We found an elevated rate of neuroimaging findings in patients following LT with 32.6% of positive studies. In our cohort, the average time after LT to a neurological complication was 4.9months post-transplant. Encephalopathy, critical illness polyneuropathy and stroke, in that order, were the most frequent neurological complications.

As a result of this, a country-wide knowledge base of the implications of heavy metals on the food chain is lacking. Thus, the present study synthesises existing literature and their findings to create a knowledge base on the vulnerability of the food chain in Nigeria. Aquatic foods, fruits, vegetables, and major staple food such as tubers are the major host of carcinogenic and mutagenic components of heavy metals in Nigeria. This study motivates the Standard Organisation of Nigeria (SON), along with other food and agricultural agencies, to intensify their efforts in monitoring and analysing food components, and we advise consumers to eat with certain degrees of caveat.

In Arab countries, however, the CRC had been reported to have increased. Despite the concerted effort in the primary prevention and widespread use of colonoscopy, to our knowledge, there have been no reports of the prevalence rate of CRC among colonoscopy recipients from Oman. This study aims to explore the CRC prevalence estimates over selected sociodemographic characteristics among colonoscopy-recipients at a tertiary hospital in Oman over five years of follow-up. The regional variations in Oman were also examined in this study. Methods This hospital-based cross-sectional study reviewed reports of colonoscopies performed over 5-years of retrospective follow-up at a tertiary hospital in Oman. CRC prevalence estimates were calculated over age, gender, governorate, and time of follow-up. Results A total of 442 CRC cases were enumerated among 3701 colonoscopies, with an overall CRC prevalence estimate of 11.9 per 100 colonoscopies (95% CI 10.9, 13.0). Gender-specific CRC prevalence was higher among males compared with females (13.3 vs. 10.5). Age-specific CRC prevalence increased with advancing age, from 2.8 among those less than 40 years of age to 26.5 among aged 70 years or more. Regional CRC prevalence was highest among residents in Batinah Governorate. Over the 5-years of follow-up, there was a slow rise in CRC prevalence with an annual increment of 0.59%. Conclusion The study provides supportive evidence for a steady increase in CRC prevalence over age categories and years of follow-up and depicted the variations of gender-specific CRC prevalence estimates over increasing age categories. The study calls for timely formulation and adoption of national CRC screening programs centered on the colonoscopy use as primary prevention and maximizing its utilization and efficiency.

This study aimed to determine the effectiveness of extraction methods on antioxidant activity of secondary metabolites of papery skin extracts and fractions of Maja Cipanas onion (Allium cepa L. var. ascalonicum). Extraction methods were maceration, percolation, reflux, and Soxhlet method, and then, concentrated extracts were fractionated by liquid-liquid extraction based on the polarity of secondary metabolites. Antioxidant activity was determined by the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The phytochemical screening showed that onion papery skin contained alkaloids, polyphenols, flavonoids, and tannins. The IC50 value of the extract, ethyl acetate fraction, and water fraction of the four extraction methods in the concentration range 25-400  μg/mL were in the range of 55.62-107.08, 31.31-84.06, and 126.05-139.82  μg/mL, respectively, while the IAA value was in the ranges of 0.25-0.49, 0.32-0.86, and 0.19-0.21, respectively. Variation in IC50 and IAA values indicate that the extraction method affects antioxidant activity, due to extracted secondary metabolites from simplicia. The highest antioxidant activity was an ethyl acetate fraction by the reflux method, while the lowest was water fraction by the percolation method. Copyright © 2020 Nyi M. Saptarini and Yulia Wardati.The general practitioner (GP) has a significant role in primary care, being more than a gatekeeper to health services access. In Italy, if a citizen moves for studies for at least 3 months, he/she can choose temporarily another GP in the new city (the so-called "Healthcare Domicile" (HD)). The aims were to estimate the university students' knowledge about the HD, evaluate the frequency of the transition to another GP, and assess the university students' attitudes towards the primary care services. In 2018, a cross-sectional pilot study was performed in study rooms among students attending the University of Turin Participation was voluntary, anonymous, and without compensation. A 25-item questionnaire collected information about the sociodemographic characteristics, health services use, health conditions and medications, HD knowledge, and HD use. The outcomes were having the GP far away, knowing HD, and not moving the GP even if aware of HD. Chi-square test, Mann-Whitney U-test, and logistic regression analyses were performed. The significance level was p ≤ 0.05. Participants were 388 and those who knew HD were 45.36%. Among those who moved to Turin (44.85%), 77.67% knew HD but did not move the GP anyway. The 72.68% used medications without prescription (the most taken nonsteroidal anti-inflammatory drugs and antibiotics). Age, nationality, and degree course type could be predictors for outcomes considered. HD knowledge was associated with a different use of healthcare resources. The data of the present paper suggest that further studies are required to better understand the framework connected with the university students' access to primary healthcare. Our results highlighted the need to implement campaigns targeted to university students to spread information about the HD and a more appropriate use of the healthcare services and medications.

There has been exponential growth in uptake from the initial in vivo case in 2010 to the present day. Early adopters of taTME are well within the mature portions of their learning curve, but there are a significant number of novice taTME surgeons. We have overviewed the critical aspects of patient selection, operating room set-up, and necessary equipment. In particular, we recommend that a one-team approach is used for the early cases, and ideally with an experienced proctor. The important technical pearls that will aid the novice taTME surgeon were also described. © Thieme Medical Publishers.
