Recent HIV outbreaks among people who use drugs (PWUD) necessitate additional HIV prevention tools. Pre-exposure prophylaxis (PrEP) is highly efficacious yet uptake among PWUD remains exceedingly low. To address multilevel, complex barriers to PrEP use among PWUD, a range of intervention strategies are needed.

The literature on interventions to optimize PrEP use among PWUD is nascent, comprising small pilots and demonstration projects in early phases of intervention development. Initial studies suggest that structural, healthcare, interpersonal, and individual-level interventions can improve PrEP use for PWUD, and a number of efficacy trials are underway. Future studies are needed to optimize the use of new PrEP modalities (e.g., injectable PrEP), simultaneously target multilevel challenges to PrEP use, and evaluate the integration of PrEP into other service settings and substance use treatment modalities.

Bariatric surgery may be associated with severe postoperative complications (SPC). Factors associated with the risk of SPC have not been fully investigated.

This study aimed to identify preoperative risk factors of SPC within 90 days and to develop a risk prediction model based on these factors.

We conducted a retrospective single-center cohort study based on a prospectively maintained database of obese patients undergoing laparoscopic bariatric surgery from October 2005 to May 2019. All SPC occurring up to the 90th postoperative day were recorded according to the Dindo-Clavien classification. Associations between potential risk factors and SPC were analyzed using a logistic regression model, and the risk prediction ("OS-SEV90 score") was computed. Based on the OS-SEV90 score, the patients were grouped into 3 categories of risk low, intermediate, and high.

Among 1963 consecutive patients, no patient died and 82 (4.2%) experienced SPC within 90 days. History of gastric or esophageal surgery (adjusted optimize the comorbidities before the surgery. Further studies are warranted to validate this score in a new independent cohort before using it in clinical practice.
A predictive model of SPC within 90 days "the OS-SEV90 score" has been developed using 9 baseline risk factors. The use of the OS-SEV90 score may help the multidisciplinary team to identify the specific risk of each patient and inform them about and optimize the comorbidities before the surgery. Further studies are warranted to validate this score in a new independent cohort before using it in clinical practice.
The aims of this systematic review were to (1) describe physical activity (PA) levels following diagnosis of primary brain cancer, (2) determine the relationship between PA levels and health outcomes, and (3) assess the effect of participating in an exercise intervention on health outcomes following a diagnosis of brain cancer.

PubMed, EMBASE, Scopus and CINAHL were searched for relevant articles published prior to May 1, 2020. Studies reporting levels of PA, the relationship between PA and health outcomes, and exercise interventions conducted in adults with brain cancer were eligible. The search strategy included terms relating to primary brain cancer, physical activity, and exercise. Two independent reviewers assessed articles for eligibility and methodological quality (according to Joanna Briggs Institute Critical Appraisal Tools). Descriptive statistics were used to present relevant data and outcomes.

15 studies were eligible for inclusion. Most adults with brain cancer were insufficiently active from diagnosis through to post-treatment. Higher levels of PA were associated with lower severity of brain cancer specific concerns and higher quality of life. Preliminary evidence suggests that exercise is safe, feasible and potentially beneficial to brain cancer symptom severity and interference, aerobic capacity, body composition and PA levels. However, the level of evidence to support these findings is graded as weak.

Evidence suggests that it is likely appropriate to promote those with brain cancer to be as physically active as possible. The need or ability of those with brain cancer to meet current PA guidelines promoted to all people with cancer remains unclear.

To clarify the need for post-operative radiation treatment in skull base chondrosarcomas (SBCs).

A retrospective analysis of patients with grade I or II SBC. Patients were divided according to post-surgical treatment strategies (A) planned upfront radiotherapy and (B) watchful waiting. Tumor control and survival were compared between the treatment groups. The median follow-up after resection was 105months (range, 9-376).

Thirty-two patients (Grade 1, n = 16; Grade 2, n = 16) were included. The most frequent location was petroclival (21, 64%). A gross total resection (GTR) was achieved in 11 patients (34%). Fourteen (44%) underwent upfront radiotherapy (group A) whereas 18 (56%) were followed with serial MRI alone (group B). The tumor control rate for the entire group was 77% and 69% at 10- and 15-year, respectively. Upfront radiotherapy (P = 0.25), extent of resection (P = 0.11) or tumor grade (P = 0.83) did not affect tumor control. The majority of Group B patients with recurrent tumors (5/7) obtained tumor control with repeat resection (n = 2), salvage radiotherapy (n = 2), or a combination of both (n = 1). The 10-year disease-specific survival was 95% with no difference between the group A and B (P = 0.50).

For patients with grade I/II SBC, a reasonable strategy is deferral of radiotherapy after maximum safe resection until tumor progression or recurrence. At that time, most patients can be successfully managed with salvage radiotherapy or surgery. Late recurrences may occur, and life-long follow-up is advisable.

Obstructive sleep apnea (OSA) may increase the risk of severe COVID-19; however, the level of potential modulation has not yet been established. The objective of the study was to determine the association between high risk of OSA, comorbidities, and increased risk for COVID-19, hospitalization, and intensive care unit (ICU) treatment.

We conducted a cross-sectional population-based web survey in adults in 14 countries/regions. The survey included sociodemographic variables and comorbidities. Participants were asked questions about COVID-19, hospitalization, and ICU treatment. Standardized questionnaire (STOP questionnaire for high risk of OSA) was included. Multivariable logistic regression was conducted adjusting for various factors.

Out of 26,539 respondents, 20,598 (35.4% male) completed the survey. Mean age and BMI of participants were 41.5 ± 16.0 years and 24.0 ± 5.0 kg/m
, respectively. The prevalence of physician-diagnosed OSA was 4.1% and high risk of OSA was 9.5%. We found that high risk of OSA (adjusted odds ratio (aOR) 1.72, 95% confidence interval (CI) 1.20, 2.47) and diabetes (aOR 2.07, 95% CI 1.23, 3.48) were associated with reporting of a COVID-19 diagnosis. High risk for OSA (aOR 2.11, 95% CI 1.10-4.01), being male (aOR 2.82, 95% CI 1.55-5.12), having diabetes (aOR 3.93, 95% CI 1.70-9.12), and having depression (aOR 2.33, 95% CI 1.15-4.77) were associated with increased risk of hospitalization or ICU treatment.

Participants at high risk of OSA had increased odds of having COVID-19 and were two times more likely to be hospitalized or treated in ICU.

The real and the imaginary are closely intertwined- sometimes to the extent that one of them is taken for the other. Considering some specific product of the imagination as if it is real amounts to a delusion - the topic of this paper. A person constructs and attributes meaning and associations to objects and people and these constructions have been made by both personal and socially shared ideas. The dilemma seems to be concerning perspectives on truth and what lies prior to the determination of this. The attempt of this article and the autoethnographic research is to comprehend the extent and diversity of delusions. This will be examined in the attempt to investigate and distinguish delusions from everyday life to what can be considered pathological hence scrutinize the borderline of healthy versus maladaptive. This borderline will furthermore be discussed with the basis of symptom criteria from the ICD- and DSM diagnosis systems. This seems to be of big importance when diagnostically comprehend the pathological elements of the delusions in the sense that the judgement could come to determine life situation. These discussions lead to an understanding of delusions as semiotically made when distinguishing between general versus pathological psychological conditions.The onset of osteonecrosis of the jaw, which is a side effect of bisphosphonates, often develops after tooth extraction; measures for its prevention have not yet been established. https://www.selleckchem.com/products/fiin-2.html While treatment with systemic administration of bone marrow stem cell-derived conditioned medium for medication-related osteonecrosis of the jaw (MRONJ) has been reported, its preventive effects have not been clarified yet, and the high degree of invasiveness of bone marrow fluid collection remains an issue. Therefore, we created a rat model of MRONJ using BP zoledronic acid, used a dental pulp stem cell-conditioned medium (DPSC-CM), which can be collected relatively easily, and locally applied it to the tooth extraction socket with atelocollagen and gelatin sponges. The preventive effect on the onset of MRONJ was subsequently examined. The results demonstrated that the bone exposure width of the extraction socket was reduced, and the mucosal covering was promoted in the atelocollagen + DPSC-CM group as compared with the other groups.
