Vaccines are one of the great achievements of medical science. They have eradicated or drastically reduced the incidence of once common diseases. It is estimated that vaccines save between 2 and 6 million lives each year, but 1.5 million more lives could be saved if coverage was increased. Vaccine hesitancy, defined by the World Health Organization as "the reluctance or refusal to vaccinate despite the availability of vaccines", is a barrier to increasing coverage that has received a great deal of attention from the media and public health academics in recent years. It is argued that many parents are reluctant to vaccinate their children because of concerns about vaccine safety, despite reassurances from doctors and public health authorities. Vaccine hesitancy is a particularly big problem in high-income countries. Observers have noted that the internet and social media play an important role in spreading fears about vaccine safety. It is, however, important to understand how the wider social and political context has influenced concerns about vaccine safety. Vaccine hesitancy appears to be one aspect of a broader breakdown in trust between some sections of the population on the one hand, and elites and experts on the other.PURPOSE Lung cancer (LC) has a significant impact on patients' health-related quality of life (HRQoL). We investigate the correlations between pre-radiation therapy HRQoL and survival. MATERIALS AND METHODS A prospective, intention-to-treat, multicentre study of 437 patients with LC recruited at the radiation oncology departments of three different institutions was conducted between 2012 and 2016. QoL was assessed using the EORTC-QLQ-C30 (v3.0) and EORTC-QLQ-LC13 questionnaires. Global health status (GHS), physical (PF), role functioning (RF), emotional (EF), cognitive (CF), and social functioning (SF) as well as symptoms scores were evaluated in univariate and multivariate analyses. RESULTS The cohort consisted of 376 men (86%) and 61 women, with a median age of 66 years (range 31-88). Histology was 72% (n = 315) non-small cell lung cancer and 28% small cell lung cancer. The most common stage was III (80%) and the median follow-up for alive patients was 30 months (range 7-76). Multivariate analysis showed that RF was associated with a lower risk of mortality (HR 0.693; p = 0.008) and recurrence (HR 0.737; p = 0.040). Additionally, lower scores on EF and PF were associated with higher mortality (HR 0.696; p = 0.003 and HR 0.765; p = 0.044, respectively). Appetite loss, constipation, and dysphagia were associated with a higher risk of mortality (HR 1.985; p  less then  0.001, HR 1.373; p = 0.036, and HR 1.659; p = 0.002, respectively), while appetite loss was the only symptom associated with a higher risk of recurrence (HR 1.525; p = 0.014). CONCLUSIONS Pre-radiation therapy scores on RF, EF, and PF and symptoms like appetite loss, dysphagia, and constipation were associated with the risk of mortality. This information could be added to other prognostic factors to guide our treatment decisions.PURPOSE OF REVIEW To examine recent key developments in the pathophysiology, diagnosis, and treatment of gastroesophageal reflux disease (GERD). RECENT FINDINGS Newer research has suggested cytokine-mediated inflammation may play a role in the physiology of GERD, implying that the underlying mechanism may not be entirely related to chemical damage due to acid. Aided by novel technologies, diagnostic testing is also moving toward elucidating individual mechanisms and better defining specific GERD phenotypes with the goal of providing directed therapy. This is especially important in current times given the increase in coverage of adverse events reportedly linked to long-term proton pump inhibitor use. As patients are looking for potential alternatives, we highlight the key recent updates in pathophysiology and understanding of GERD and current medical and endoscopic/surgical options and explore the exciting treatments in the pipeline.PURPOSE Poor sleep quality is common in medical students and is associated with a number of negative health outcomes. However, the prevalence estimates of poor sleep quality in medical students vary widely across studies. We thus conducted a meta-analysis of the prevalence of poor sleep quality and its mediating factors in medical students. METHODS A systematic literature search of PubMed, EMBASE, Web of Science, PsycINFO, and Medline Complete was performed. The random-effects model was used to analyze the pooled prevalence of poor sleep quality and its 95% confidence intervals (CIs). RESULTS A total of 57 studies with 25,735 medical students were included. The pooled prevalence of poor sleep quality was 52.7% (95% CI 45.3% to 60.1%) using the Pittsburgh Sleep Quality Index (PSQI). The pooled mean total PSQI score across 41 studies with available data was 6.1 (95% CI 5.6 to 6.5). Subgroup analyses found that PSQI cutoff value and study region were associated with the prevalence of poor sleep quality (P = 0.0003 VS. PF-9366 datasheet P = 0.005). Across the continents, poor sleep quality was most common in Europe, followed by the Americas, Africa, Asia, and Oceania. Meta-regression analyses found that smaller sample size (slope = - 0.0001, P = 0.009) was significantly associated with higher prevalence of poor sleep quality. CONCLUSIONS Poor sleep quality is common among medical students, especially in Europe and the Americas continets. Due to the negative health outcomes, regular screening of poor sleep quality and effective interventions are needed for medical students.PURPOSE OF REVIEW The ANRS 12249 treatment as prevention (TasP) trial investigated the impact of a universal test and treat (UTT) approach on reducing HIV incidence in one of the regions of the world most severely affected by the HIV epidemic-KwaZulu-Natal, South Africa. We summarize key findings from this trial as well as recent findings from controlled studies conducted in the linked population cohort quantifying the long-term effects of expanding ART on directly measured HIV incidence (2004-2017). RECENT FINDINGS The ANRS TasP trial did not-and could not-demonstrate a reduction in HIV incidence, because the offer of UTT in the intervention communities did not increase ART coverage and population viral suppression compared to the standard of care in the control communities. Ten controlled studies from the linked population cohort-including several quasi-experimental study designs-exploit heterogeneity in ART exposure to show a consistent and substantial impact of expanding provision of ART and population viing with HIV in early stages of the disease to participate in HIV treatment. Such innovations and new approaches are required for the true potential of UTT to be realized.PURPOSE OF REVIEW This review describes social determinants of HIV in two geographic and epidemic settings, the Dominican Republic (DR) and Tanzania, among female sex workers (FSW), their influence on HIV outcomes including 90-90-90 goals, and the development and impact of tailored, context driven, community empowerment-based responses in each setting. RECENT FINDINGS Our review documents the significance of social determinants of HIV including sex work-related stigma, discrimination, and violence and the impact of community empowerment-based approaches on HIV incidence in Tanzania and other HIV prevention, treatment, and care outcomes, including care engagement and adherence, in the DR and Tanzania. Community empowerment approaches where FSW drive the response to HIV and strategically engage partners to target socio-structural and environmental factors can have a demonstrable impact on HIV prevention, treatment, and care outcomes. Such approaches can also support further gains towards reaching the 90-90-90 across geographies and types of epidemics.PURPOSE OF REVIEW The proportion of overweight and obese persons with HIV (PWH) has increased since the introduction of antiretroviral therapy (ART). We aim to summarize recent literature on risks of weight gain, discuss adipose tissue changes in HIV and obesity, and synthesize current understanding of how excess adiposity and HIV contribute to metabolic complications. RECENT FINDINGS Recent studies have implicated contemporary ART regimens, including use of integrase strand transfer inhibitors and tenofovir alafenamide, as a contributor to weight gain, though the mechanisms are unclear. Metabolic dysregulation is linked to ectopic fat and alterations in adipose immune cell populations that accompany HIV and obesity. These factors contribute to an increasing burden of metabolic diseases in the aging HIV population. Obesity compounds an increasing burden of metabolic disease among PWH, and understanding the role of fat partitioning and HIV- and ART-related adipose tissue dysfunction may guide prevention and treatment strategies.BACKGROUND Regulatory T cell (Treg) plays an essential role in regulating anti-tumor immunity. The aim of this study was to investigate the effect of transarterial chemoembolization (TACE) on Treg in hepatocellular carcinoma (HCC) patients. METHOD The frequency of peripheral blood Tregs in 27 HCC patients who underwent TACE were measured at baseline and 1 month after TACE. The frequency of peripheral blood Tregs at baseline were compared with those in 23 healthy controls. Tregs were further classified into three subpopulations [Treg (I), Treg (II), Treg (III)] based on expression levels or markers and their function. The patients were divided into two groups according to tumor response after TACE; complete response group and incomplete response group. The correlations between the frequency of Treg and clinical factors were analyzed. RESULTS The frequency of Treg in HCC patients (7.52%) was significantly higher than in healthy controls (4.99%) at baseline. Regarding Treg subpopulations, the frequency of Treg (II) was significantly higher in HCC patients (2.51%) than in healthy controls (0.60%). In comparison of Treg numbers at baseline and post-TACE by tumor response, the change of Treg (III) in complete response group from baseline to post-TACE was significantly decreased (63.8 → 53.2/mm3). Patients with a high post-TACE Treg (III) (3.8 months) exhibited a significantly shorter median time to progression than those with a low post-TACE Treg (III) (11.6 months). In multivariate analyses, hypoalbuminemia (hazard ratio 3.324; 95% CI 1.098-10.063, p = 0.034) and high post-TACE Treg (III) (hazard ratio 3.080; 95% CI 1.091-8.696, p = 0.034) were significant factors for associating with progression. CONCLUSIONS The frequency of Tregs in HCC patients was significantly higher than in healthy controls. In addition, patients with a high post-TACE Treg (III) exhibited a significantly lower progression-free survival rate than those with a low post-TACE Treg (III).PURPOSE This study aimed to assess radiological findings of adenomyomatosis advancing to chronic inflammation to differentiate between adenomyomatosis with and without chronic inflammation. MATERIALS AND METHODS We retrospectively identified 79 patients with pathologically proven adenomyomatosis without (n = 10) or with chronic inflammation (n = 69), who underwent computed tomography (CT) and magnetic resonance imaging (MRI) followed by surgery. MRI analysis included evaluation of GB wall-thickening type, presence and location of intramural cysts, and presence of stones. CT analysis included GB wall-thickening type only. Multivariate logistic regression analysis was used to identify the image-based findings of adenomyomatosis associated with chronic inflammation. RESULTS On univariate analysis, MRI-based GB wall-thickening type and presence of stones, and CT-based GB wall-thickening type were significantly different between adenomyomatosis with and without chronic inflammation. On multivariate analysis, only the absence of stones was identified as a significant predictor of adenomyomatosis without chronic inflammation (odds ratio 5.
