Seroprevalence of Hepatitis A virus and Hepatitis E virus in patients presenting with acute viral hepatitis: A retrospective study of 2-years at tertiary care Hospital, Himachal Pradesh in Northern India

: Hepatitis-A virus and Hepatitis-E virus are spread enterically, resulting in acute viral hepatitis (AVH) in developing countries. Fecal-oral transmitted hepatitis cause major health problems in our country. The aim of present study is to determine the seroprevalence of HAV and HEV in AVH patients attending the tertiary care hospital at Dr. Rajendra Prasad Govt. Medical College Kangra at Tanda, Himachal Pradesh (DRPGMC). Insufficient data makes it difficult to determine an accurate prevalence of illness in this region of India.: The Viral Research and Diagnostic Laboratory (VRDL), in the Department of Microbiology at DRPGMC Tanda, Himachal Pradesh, consolidated retrospective data of 2-years duration. The study population included 784 serum samples received from outdoor and indoor patients were considered in the study.: Of the 784 serum samples that were chosen for our study, HAV and HEV reactive patients showed a seroprevalence of 11.20% and 1.80% respectively. During two years of the study, the co-infection rate of HAV and HEV in patients with acute viral hepatitis was 0.5%. Compared to females (31.80% and 42%), males reported higher seroprevalence of HAV (68.10%) and HEV (57.10%). Further data shows that HAV infection was observed in all age groups and the highest prevalence was reported in the age range from 11 to 20 years. The HEV infection was not observed in the pediatric age groups, it was only observed in adults. Maximum prevalence of HEV was reported in the age group of 21-30 years. The highest number of reactive cases was recorded in the month of August and September.: We found that the prevalence of HAV is significantly higher than that of HEV during two years of study period. In this study, we observed that HAV is more predominant in males as compare to females.HEV infections were only observed in adults.

Impact of Atopic Dermatitis on Adult Women's Lives: A Survey of 1,009 French Women.

Atopic dermatitis (AD) is one of the most common inflammatory diseases, and has a higher prevalence among females in adulthood. The aim of this observational, cross-sectional, survey-based study was to evaluate the impact of AD on the daily lives of adult women patients. A scientific committee composed exclusively of women constructed a specific questionnaire in partnership with the French Eczema Association. Severity of AD was evaluated with the Patient-Oriented Eczema Measure (POEM). A sample of 1,009 adult women (mean age ± standard deviation: 41.8 ± 14.2 years) with AD was identified from a representative sample of the French population (82% response rate 1,230 women surveyed). According to the POEM, 50.64% (n = 511) of subjects were identified as having mild AD, 39.35% (n = 397) moderate AD, and 10.01% (n = 101) severe AD. Overall, 67.7% (n = 682) reported that their eczema involved a visible area (face, neck or hands), and 19.6% (n = 198) a sensual area (breasts/chest, genital area or buttocks). Of the 720 women with menstrual cycles, exacerbations of AD were reported to occur mostly before (50.6%) and during (48.3%) menstruation. A small proportion of women, 7.3% (n = 74), reported being afraid of becoming pregnant because of their eczema. If AD involvement was in a visible area it had a greater impact on romantic relationships, sexual relationships and occupation. If AD involvement was in a sensual area it had a greater influence on romantic relationships and sexuality. Particular attention should be given to patients with localization of AD on the face, neck or hands, as they have a higher risk of social exclusion. Moreover, these results should encourage health professionals to ask patients with AD about the possible involvement of sensual areas.

Prevalence and associated factors of psychiatric comorbidities in epilepsy in the Casablanca-Settat region of Morocco: A cross-sectional study.

To determine the estimated prevalence of anxiety, depression, and anxiety-depression syndrome (ADS) and to identify the associated factors in Moroccan people with epilepsy (PWE). A cross-sectional study was conducted among adult PWE (June 2021-December 2022) in the Casablanca-Settat region. PWE were interviewed by completing a questionnaire collecting sociodemographic and clinical data. Anxiety and depression were assessed by the Hospital Anxiety and Depression Scale (HADS). Out of 21 points, a score ≥8 is in favor of considerable anxiety/depression symptoms and a sum of the two scores ≥15 indicates the presence of ADS. Data were analyzed using Statistical Package for Social Sciences (SPSS) 21.0. p-values ≤0.05 were considered statistically significant and logistic regression was performed to determine the associated factors. Among 294 PWE, the median age was 39 years (interquartile range [IQR]: 25.75-54.00). The median anxiety, depression, and ADS scores were 8 (IQR: 5.00-10.00), 7 (IQR: 4.00-10.00), and 15 (IQR: 10.00-20.00), respectively. Anxiety, depression, and ADS were revealed in 51.4%, 44.9%, and 51.0% of PWE, respectively. Depression was the only predictor for anxiety (aOR = 24.20; 95%CI: 12.45-47.01). Antiseizure polytherapy (aOR = 3.35; 95%CI: 1.72-6.54) and anxiety (aOR = 24.04; 95%CI: 12.12-47.67) were the factors associated with depression. The risk of ADS was increased by female gender (aOR = 2.83; 95%CI: 1.68-4.78), antiseizure polytherapy (aOR = 2.75; 95%CI: 1.62-4.65), structural epilepsy (aOR = 1.73; 95%CI: 1.01-2.94), and the presence of concomitant conditions with epilepsy (aOR = 1.96; 95%CI: 1.16-3.31). Our study reports high psychiatric comorbidity prevalence in epilepsy, which supports the bidirectional link hypothesis. Associated factors found are important in the prognosis and prevention. The neural mechanisms underlying epilepsy tend to expose PWE to psychiatric disorders. Our study aims to quantify the rate of psychiatric comorbidities and their predictive factors in Moroccan PWE. The estimated prevalences of significant symptoms of anxiety, depression, and ADS were 51.4%, 44.9%, and 51.0%, respectively. Depression was the predictor of anxiety. Antiseizure polymedication and anxiety were the associated factors with depression. The risk of SAD was increased by female gender, antiseizure polymedication, structural epilepsy, and concomitant diseases with epilepsy. Our results are important for considering the psychiatric aspect of PWE and improving their care and quality of life.

MASLD and MASH at the crossroads of hepatology trials and cardiorenal metabolic trials.

Steatotic liver disease (SLD) is a worldwide public health problem, causing considerable morbidity and mortality. Patients with SLD are at increased risk for major adverse cardiovascular (CV) events, type 2 diabetes mellitus and chronic kidney disease. Conversely, patients with cardiometabolic conditions have a high prevalence of SLD. In addition to epidemiological evidence linking many of these conditions, there is evidence of shared pathophysiological processes. In December 2022, a unique multi-stakeholder, multi-specialty meeting, called MOSAIC (Metabolic multi Organ Science Accelerating Innovation in Clinical Trials) was convened to foster collaboration across metabolic, hepatology, nephrology and CV disorders. One of the goals of the meeting was to consider approaches to drug development that would speed regulatory approval of treatments for multiple disorders by combining liver and cardiorenal endpoints within a single study. Non-invasive tests, including biomarkers and imaging, are needed in hepatic and cardiorenal trials. They can be used as trial endpoints, to enrich trial populations, to diagnose and risk stratify patients and to assess treatment efficacy and safety. Although they are used in proof of concept and phase 2 trials, they are often not acceptable for regulatory approval of therapies. The challenge is defining the optimal combination of biomarkers, imaging and morbidity/mortality outcomes and ensuring that they are included in future trials while minimizing the burden on patients, trialists and trial sponsors. This paper provides an overview of some of the wide array of CV, liver and kidney measurements that were discussed at the MOSAIC meeting.

The feasibility, acceptability and appropriateness of screening for frailty in Australians aged 75 years and over attending Australian general practice

Background Globally, frailty is associated with a high prevalence of avoidable hospital admissions and emergency department visits, with substantial associated healthcare and personal costs. International guidelines recommend incorporation of frailty identification and care planning into routine primary care workflow to support patients who may be identified as pre-frail/frail. Our study aimed to: (1) determine the feasibility, acceptability, appropriateness and determinants of implementing a validated FRAIL Scale screening Tool into general practices in two disparate Australian regions (Sydney North and Brisbane South); and (2) map the resources and referral options required to support frailty management and potential reversal. Methods Using the FRAIL Scale Tool, practices screened eligible patients (aged ≥75 years) for risk of frailty and referred to associated management options. The percentage of patients identified as frail/pre-frail, and management options and referrals made by practice staff for those identified as frail/pre-frail were recorded. Semi-structured qualitative interviews were conducted with practice staff to understand the feasibility, acceptability, appropriateness and determinants of implementing the Tool. Results The Tool was implemented by 19 general practices in two Primary Health Networks and 1071 consenting patients were assessed. Overall, 80% of patients (n = 860) met the criterion for frailty: 33% of patients (n = 352) were frail, and 47% were pre-frail (n = 508). They were predominantly then referred for exercise prescription, medication reviews and geriatric assessment. The Tool was acceptable to staff and patients and compatible with practice workflows. Conclusions This study demonstrates that frailty is identified frequently in Australians aged ≥75 years who visit their general practice. It’s identification, linked with management support to reverse or reduce frailty risk, can be readily incorporated into the Medicare-funded annual 75+ Health Assessment.

The Effectiveness of Modular Transdiagnostic Cognitive Behavioral Therapy Versus Treatment as Usual for Youths Displaying School Attendance Problems: A Randomized Controlled Trial.

School attendance problems (SAPs) are associated with negative short- and long-term outcomes. Despite high prevalence of SAPs, there is a shortage of evidence-based interventions. Existing approaches often target either school refusal or truancy, leaving a gap in effective interventions addressing both types of SAPs. This randomized controlled trial (RCT) assessed the effectiveness of Back2School (B2S), a modular transdiagnostic cognitive behavioral therapy (CBT) for SAPs, compared to treatment as usual (TAU). Outcomes included youths' school attendance and mental health. A group (B2S, TAU) × time (Pre, Post, 3-Month Follow-Up) design involving 152 youths (B2S; n = 74, TAU; n = 78) with SAPs (i.e., ≥ 10% absence in the past three months), aged 6-16 years (M = 12.2, SD = 2.2, males = 60%) were used. B2S comprised three months of CBT with youths, parents, and school involvement, while TAU comprised public and/or private intervention services. On average, youths in B2S received 15.0, (SD = 3.9) hours of intervention, while those in TAU received 13.4, (SD = 21.6). Intervention effects were investigated using mixed linear models. Both B2S and TAU exhibited significant within-group improvements in school attendance, with no significant differences between them. However, the B2S group significantly outperformed TAU in reducing youths' emotional problems, conduct problems, problems with peers, the overall impact of problems, and increasing youths self-efficacy for attending school and parent self-efficacy for dealing with a SAP. This RCT represents the first evaluation of a modular transdiagnostic CBT for youths displaying SAPs, showing significant mental health and self-efficacy benefits. (Clinical trial registration: ClinicalTrials.gov: NCT03459677).

Remnant Gastrectomy and Gastric Bypass: A Systematic Review of Indications and Outcomes of Resectional Gastric Bypass.

In this systematic review, we aim to evaluate the reasons and outcomes behind remnant gastrectomy with or after gastric bypass procedures. A total of 66 studies examining 1918 patients were included in this study with 70% of female predominance. Twenty studies reported RGB on 1751 patients and 46 studies reported remnant gastrectomy after gastric bypass in 167 patients. The most common etiology of RGB was related to the in situ remnant stomach neoplasia in 10 studies on 981 patients; mostly for preventive intentions in high prevalence areas. Remnant gastrectomy after gastric bypass was performed to treat a complication such as GGF, retrograde bile reflux gastritis, cancer mostly adenocarcinoma. Studies revealed that RGB has similar weight loss in comparison to standard Roux-en-Y gastric bypass.

MORPHOLOGICAL CHANGES IN RAT SKIN AFTER THERMAL BURNS

Every day around the world, children and adults suffer from burn injuries. Burn injury is one of the global health problems due to its high prevalence and mortality. The skin is the largest multifunctional human organ. The area of the entire skin is on average 1.7-1.9 square meters. The skin has a wide variety of functions from protective to energy-saving and tactile. Burns have a long history, but new methods of study are needed, this is due to the increase in the frequency of burns in everyday life, production, as well as the complexity of the pathogenesis and treatment of burn disease. Pathological changes that occur in the body of burned animals lead to the fact that in the first hours with extensive burn injury, circulatory disorders occur in parenchymal organs, especially in the liver, lungs and adrenal glands. In the future, with severe intoxication, severe dystrophic processes occur in the muscles of the heart and other internal organs. Recently, the main areas of research into the pathogenesis of inflammation have become immunological, at the morphological level it has not been sufficiently studied. The article shows the morphological features of the study in thermal burns of the skin of rats during treatment with a different mechanism of action. Rats in the amount of 15 pieces were divided into 3 groups: the first control group with a burn without treatment, the second group with a thermal burn, to which levomekol gel was applied to the burn area, the third group was treated with powder from the medicinal plant yarrow Achillea millefolium L. On the 3rd, 7th, 14th, and 21st days, the rats were taken out of the experiment, after which the skin pieces were fixed in 10% formalin for further histological examination.

Prevalence of malaria and associated risk factors among household members in South Ethiopia: a multi-site cross-sectional study

BackgroundDespite continuous prevention and control strategies in place, malaria remains a major public health problem in sub-Saharan Africa including Ethiopia. Moreover, prevalence of malaria differs in different geographical settings and epidemiological data were inadequate to assure disease status in the study area. This study was aimed to determine the prevalence of malaria and associated risk factors in selected rural kebeles in South Ethiopia.MethodsA community-based cross-sectional study was conducted between February to June 2019 in eight malaria-endemic kebeles situated in four zones in South Ethiopia. Mult-stage sampling techniques were employed to select the study zones, districts, kebeles and households. Blood sample were collected from 1674 participants in 345 households by finger prick and smears were examined by microscopy. Sociodemographic data as well as risk factors for Plasmodium infection were collected using questionnaires. Bivariate and multivariate logistic regressions were used to analyse the data.ResultsThe overall prevalence of malaria in the study localities was 4.5% (76/1674). The prevalence was varied among the study localities with high prevalence in Bashilo (14.6%; 33/226) followed by Mehal Korga (12.1%; 26/214). Plasmodium falciparum was the dominant parasite accounted for 65.8% (50/76), while Plasmodium vivax accounted 18.4% (14/76). Co-infection of P. falciparum and P. vivax was 15.8% (12/76). Among the three age groups prevalence was 7.8% (27/346) in age less than 5 years and 7.5% (40/531) in 5–14 years. The age groups > 14years were less likely infected with Plasmodium parasite (AOR = 0.14, 95% CI 0.02–0.82) than under five children. Non-febrile individuals 1638 (97.8%) were more likely to had Plasmodium infection (AOR = 28.4, 95% CI 011.4–70.6) than febrile 36 (2.2%). Individuals living proximity to mosquito breeding sites have higher Plasmodium infection (AOR = 6.17, 95% CI 2.66–14.3) than those at distant of breeding sites.ConclusionsMalaria remains a public health problem in the study localities. Thus, malaria prevention and control strategies targeting children, non-febrile cases and individuals living proximity to breeding sites are crucial to reduce malaria related morbidity and mortality.

High prevalence of severe pain is associated with low opioid availability in patients with advanced cancer: Combined database study and nationwide questionnaire survey in Japan.

Opioid availability for the palliative care of patients with advanced cancer is increasing globally. However, opioid availability remains extremely low in Japan. We investigated whether pain is appropriately controlled by low-dose opioid prescriptions in patients with advanced cancer in Japan. A web-based nationwide survey for caregivers from 2000 community comprehensive support care centers was performed in Japan to assess details about pain in the 30 days before patients died of end-stage cancer. Separately, the data for opioid prescription doses and medical services in the 90 days before the death of patients with cancer were extracted from a health insurance claim database. Responses from 1034 responders were retrieved and 665 patients were included. In total, 254 patients (38.2%) complained of severe-to-intolerable cancer-related pain. The median cumulative prescription dose of opioids in the 90 days before patient death was 311.0 mg by oral morphine equivalent doses. Multiple regression analyses across prefectures revealed that the proportion of patients with severe-to-intolerable cancer-related pain was negatively associated with the cumulative opioid consumption expressed as morphine-equivalent doses within 90 days before death. The very low availability of opioids for patients with end-stage cancer could result in high rate of severe-to-intolerable cancer-related pain patients. There were several limitations in this study, and the interpretations of the findings should be carefully. However, the increase in the absolute dose of opioids could improve the palliative care framework to the pain control levels of the global standard.

F-actin/DRP1 axis-mediated mitochondrial fission promotes mitophagy in diabetic submandibular glands.

Diabetes is accompanied by a high prevalence of hyposalivation, causing severe damage to oral and systemic health. Mitochondrial dynamics play important roles in the pathogenesis of various diabetic complications; however, little is known about their roles in diabetic hyposalivation. A diabetic mouse model and a high glucose (HG)-induced diabetic submandibular gland (SMG) cell model were employed. More mitochondria surrounded by autophagosomes and higher expression of mitophagy-related proteins were detected in the SMGs of diabetic mice and HG-treated SMG cells. In diabetic SMGs, dynamin-related protein 1 (DRP1) was upregulated, whereas mitofusin-2 was downregulated both invivo and invitro. Shortened mitochondria and impaired mitochondrial functions were observed in the HG group. A DRP1-specific inhibitor, mdivi-1, suppressed mitochondrial fission and mitophagy, as well as restored mitochondrial functions in the HG condition. Moreover, the interaction of F-actin and DRP1 was enhanced in the diabetic group. Inhibiting F-actin with cytochalasin D repaired the injured effects of HG on mitochondrial dynamics and functions. Conversely, the F-actin-polymerization-inducer jasplakinolide aggravated mitochondrial fission and dysfunction. F-actin contributes to HG-evoked mitochondrial fission by interacting with DRP1, which induces mitophagy and impairs mitochondrial function in SMG cells, ultimately damaging the SMG.

Association of hepatic steatosis and liver fibrosis with chronic obstructive pulmonary disease among adults

With high prevalence and substantial mortality, metabolic dysfunction-associated steatotic liver disease and chronic obstructive pulmonary disease (COPD) are significant public health concerns. Utilizing a large, population-based dataset from the National Health and Nutrition Examination Survey, our study probes the relationship between COPD prevalence and hepatic steatosis and fibrosis, as measured by Vibration-Controlled Transient Elastography. We analyzed data from 693 individuals with COPD and 7229 without. Through weighted multivariate logistic regression analysis, a restricted cubic spline curve, and threshold effect analysis, we investigated the correlation between the severity of hepatic steatosis and fibrosis and the presence of COPD. Our findings revealed a positive correlation between the controlled attenuation parameter (CAP) and COPD prevalence [OR = 1.03 (95% CI 1.01, 1.05)], even after multivariate adjustment. Furthermore, we observed a U-shaped association between CAP and COPD, where the inflection point, CAP value of 264.85 dB/m, corresponded to the lowest COPD prevalence. Our study emphasizes a substantial and complex link between hepatic steatosis and COPD. These findings urge healthcare professionals to factor liver health into COPD management and prompt further exploration into the underlying mechanisms. This could pave the way for the development of improved prevention and treatment strategies.

Association between pulse pressure and carotid plaques in old adults with uncontrolled hypertension: results from a community-based screening in Hangzhou, China

BackgroundThere is a broad pulse pressure (PP) and a high prevalence of carotid plaques in old adults. Previous studies have indicated that PP is strongly associated with carotid plaque formation. This study aimed to explore this association in old adults with uncontrolled hypertension.Methods1371 hypertensive patients aged ≥ 60 years with uncontrolled hypertension were enrolled in a community-based screening in Hangzhou, China. Carotid plaques were assessed using ultrasonography. Logistic regression models were used to estimate the association between PP and carotid plaques by odds ratios (ORs) and 95% confidence intervals (CIs).ResultsCarotid plaques were detected in 639 (46.6%) of subjects. Multiple plaques were found in 408 (63.8%) and soft plaques in 218 (34.1%). Elevated PP was associated with a high prevalence of carotid plaques. After adjusting for traditional risk factors, compared to patients within the lowest tertile of PP, those within the highest tertiles had an increased risk of carotid plaques (OR 2.061, CI 1.547–2.745). For each 1-SD increase, the risk increased by 40.1% (OR 1.401, CI 1.237–1.587). There was a nonlinear association between PP and carotid plaques (P nonlinearity = 0.039). The risk increased rapidly after the predicted PP level reached around 60 mmHg. The associations were stronger among participants with multiple and soft plaques.ConclusionsOur findings suggested that PP was independently associated with carotid plaques in old adults with uncontrolled hypertension who have an increased risk of atherosclerosis.

High prevalence of copy number variations in the Japanese participants with suspected MODY.

Maturity-Onset Diabetes of the Young (MODY) is a diabetes mellitus subtype caused by a single gene. The detection rate of the responsible gene is 27% in the United Kingdom, indicating that the causative gene remains unknown in the majority of clinically diagnosed MODY cases. To improve the detection rate, we applied comprehensive genetic testing using whole exome sequencing (WES) followed by Multiplex Ligation-dependent Probe Amplification (MLPA) and functional analyses. Twenty-one unrelated Japanese participants with MODY were enrolled in the study. To detect copy number variations (CNVs), WES was performed first, followed by MLPA analysis for participants who were negative on the basis of WES. Undetermined variants were analyzed according to their functional properties. WES identified 7 pathogenic and 3 novel likely pathogenic variants in the 21 participants. Functional analyses revealed that 1 in 3 variants was pathogenic. MLPA analysis applied to the remaining 13 undetermined samples identified 4 cases with pathogenic CNVs: 3 in HNF4A and 1 in HNF1B. Pathogenic variants were identified in 12 participants (12/21, 57.1%) - relatively high rate reported to date. Notably, one-third of the participants had CNVs in HNF4A or HNF1B, indicating a limitation of WES-only screening.

Bloodborne pathogens in beef herds – a Kansas practitioner’s perspective

Management options for bloodborne diseases depend on preva­lence (herd level and geographic), disease stage and production class. Opportunities to manage disease can be classified ac­cording to disease stage. Newer studies show that, in contrast to older studies, there is not currently a known legal way to clear animals of anaplasmosis. The only currently labeled products for treatment of acute clinical anaplasmosis are injectable oxy­tetracyclines. For a time, an enrofloxacin product (Baytril-CA) was marketed with a label for treatment of anaplasmosis, but the conditional approval application has been withdrawn. Op­portunities for leukosis management are limited to exposure control as there are no effective treatments for animals in the clinical stage and no effective methods to clear infected non-clinical animals. Due to the relatively high prevalence in beef herds, a strict test-and-cull strategy is not practical. Instead identifying animals with high pre-viral load who are most infectious provides an option to decrease disease levels with reasonable economics at the farm level. More research is neces­sary to fully quantify production effects for carrier animals of both bovine leukosis and anaplasmosis.

Development and content validity of the DizzyQuest

IntroductionVestibular disorders have a high prevalence and impact on general health. Currently questionnaires to measure vestibular symptoms and the impact on daily life, do not capture disease-specific symptoms or induce recall bias. The DizzyQuest was introduced, to measure vestibular symptoms in the flow of daily life, using the ecological momentary assessment (EMA) strategy. The development and content validity of the DizzyQuest are described in this article.MethodsThe development process consisted of two stages: First, the development of a concept version of the DizzyQuest based on the conceptual model of positive health, semi-structured interviews with patients diagnosed with bilateral vestibulopathy (BV) and expert input. Second, the assessment of content validity through a 4-week pilot trial, followed by focus group meetings with patients and professionals separately.ResultsPatient interviews, an expert meeting and a conceptual model resulted in the first pilot version of the DizzyQuest, which included a morning-, within-day-, evening- and attack-questionnaire. To report patient characteristics, complimentary patient- and doctor-questionnaires were added. The pilot trial (N = 5) and two patient focus group meetings resulted in multiple suggestions for response options. Two professional focus group meetings provided recommendations for sampling time and sampling schedule. As a result, two versions of the DizzyQuest were developed, consisting of a regular DizzyQuest (DQ) and an extended DizzyQuest-XL (DQ-XL).ConclusionThe DizzyQuest enables the administration of multiple questionnaires during the flow of daily life, therefore increasing reliability and ecological validity. The DQ and DQ-XL, using a big data approach, has the potential to improve precision medicine.

Descriptive study on substance uses and risk of sexually transmitted infections in the practice of Chemsex in Spain

BackgroundIn recent years, there has been an increasing use of sex-related substances (known as “Chemsex”) to facilitate, intensify, and prolong the sexual experience of men who have sex with men. This phenomenon poses a public health problem, increasing the risk of sexually transmitted infections (STIs) and mental disorders.ObjectiveThe primary aim of this study was to delve into the correlation between substance use and sexual health, specifically examining the association between different substances used and the risk of sexually transmitted infections (STIs) in the context of Chemsex in Spain.MethodsAn observational, descriptive, cross-sectional study was conducted among 563 Spanish participants between January and April 2023. Non-probabilistic purposive sampling was used by the investigators. The researchers administered a questionnaire to men who have sex with men who use substances, especially in the sexual sphere, in all the autonomous communities of Spain.Results14.7% reported having practiced slamsex in the last year, and 17.94% were diagnosed with a Sexually Transmitted Infection in the previous 6 months. Of these, 21% were on PREP treatment, with the main STIs being gonorrhea (p < 0.001), chlamydia (p < 0.001), genital herpes (p = 0.020), and syphilis (p < 0.001). The 63.7% used methamphetamines as the main drug in the practice of chemsex.DiscussionChemsex in Spain is linked to a high prevalence of STIs, especially gonorrhea and chlamydia, even among those on PrEP treatment. The use of various drugs during chemsex, such as amyl nitrite, GHB, ecstasy, and others, correlates with higher rates of STIs, highlighting the need for interventions to reduce risk and harm. The drugs most associated with slamsex include ketamine, mephedrone, and methamphetamine, underscoring the importance of addressing the risk behaviors associated with this activity.ConclusionThis study shows that chemsex appears to be associated with a high prevalence among men who have sex with men. Who use multiple substances in a sexual context, and are particularly exposed to sexually transmitted infections (STIs), indicating a particular need for STI prevention and care in this group.

Anatomic considerations during placement of mandibular retromolar miniplates for orthodontic anchorage – A study of the characteristics of retromolar fossa

Objectives: The mandibular retromolar area offers a novel site for orthodontic skeletal anchorage. It houses the retromolar foramen (RMF), and surgical interventions in this area can lead to undesirable outcomes. This study aims to assess the characteristics of the RMF and its relation to the occlusal plane (OP) using cone-beam computed tomography (CBCT) data. Material and Methods: This cross-sectional observational in vitro study involved the analysis of CBCT data from 136 samples (68 males and 68 females) within the age range of 18–40 years. The study focused on factors such as the presence or absence of the RMF, whether it was unilateral or bilateral, the number of foramina on each side, and the distance of the RMF from the OP. Data analysis was conducted using the Statistical Package for the Social Sciences software, with P < 0.05 deemed statistically significant at a 95% confidence level. Results: About 39% of the sample showed the presence of RMF. The prevalence of unilateral RMF was higher than that of bilateral RMF. The mean distance of RMF above the OP was 5.99 mm, and that below the OP was 3.82 mm. Conclusion: The high prevalence (39%) of RMF suggests that the retromolar fossa region should be evaluated before the placement of mini-plates. The prevalence of RMF above the OP was significantly higher than that below the OP.

The use of antibiotics in the early stage of acute exacerbation of chronic obstructive pulmonary disease in patients without obvious signs of infection: a multicenter, randomized, parallel-controlled study

IntroductionChronic obstructive pulmonary disease (COPD) is a chronic respiratory disease with high prevalence and mortality. In some acute exacerbations of COPD (AECOPD) in patients with no obvious signs of infection, early antibiotic treatment seems to clinically improve the disease, but more studies are needed to determine the prognostic impact of antibiotic treatment in AECOPD patients with no obvious signs of infection.PurposeTo clarify the impact of antibiotic treatment on the short-term and long-term prognoses of AECOPD patients without obvious signs of infection.MethodsThe impact of the two treatment methods on the prognosis of patients was compared at 30, 90, 180, and 360 days after discharge. A multicenter, randomized, parallel-controlled clinical trial was conducted in a department of respiratory and critical care medicine in Central China. All patients met the inclusion criteria for AECOPD, and the patients were randomly assigned to the antibiotic group or the nonantibiotic group at a 1:1 ratio. Patients in the antibiotic group were given moxifloxacin 400 mg/day intravenously for 7 days. Patients in the nonantibiotic group were intravenously injected with the same amount of normal saline as the amount of moxifloxacin given to those in the antibiotic group for 7 days.ResultsThere were 406 patients in the antibiotic group and 410 patients in the nonantibiotic group. During the short-term and long-term follow-ups, the acute exacerbation frequency, intensive care unit (ICU) treatment rate, mortality, and mMRC and CAT scores were not significantly different between the two groups (p > 0.05). At the 180- and 360-day follow-ups, the forced expiratory volume in 1 s (FEV1%) and peak expiratory flow (PEF) were not significantly different between the two groups (p > 0.05). The 30-day readmission rate was significantly lower in the antibiotic group than in the nonantibiotic group (p < 0.05). The time from discharge to the first acute exacerbation was not significantly different between the two groups (p > 0.05). The length of the first hospital stay after discharge was significantly lower in the antibiotic group (5.84 days) than in the nonantibiotic group (6.75 days) (p < 0.05). At the 30-day follow-up, the acute exacerbation frequency, age, C-reactive protein (CRP) level, and sputum viscosity were significantly greater in the nonantibiotic group than in the antibiotic group (p < 0.05). In addition, according to the receiver operating characteristic (ROC) analysis, the frequency of acute exacerbations at the 30-day follow-up was significantly greater in COPD patients aged >62.5 years, with a CRP level >12.56 mg/L or with a sputum viscosity >III, in the nonantibiotic group than in those in the antibiotic group, suggesting that the short-term prognosis was poor.ConclusionPatients who are >62.5 years of age, have a CRP concentration >12.56 mg/L, or have a sputum viscosity >III without obvious signs of infection should be treated with antibiotics to improve their short-term prognosis.Clinical Trial Registration:(https://www.chictr.org.cn), (ChiCTR1800018921)

“I don’t know if I can keep doing this”: a qualitative investigation of surgeon burnout and opportunities for organization-level improvement

IntroductionBurnout is a pressing issue within surgical environments, bearing considerable consequences for both patients and surgeons alike. Given its prevalence and the unique contextual factors within academic surgical departments, it is critical that efforts are dedicated to understanding this issue. Moreover, active involvement of surgeons in these investigations is critical to ensure viability and uptake of potential strategies in their local setting. Thus, the purpose of this study was to explore surgeons’ experiences with burnout and identify strategies to mitigate its drivers at the level of the organization.MethodsA qualitative case study was conducted by recruiting surgeons for participation in a cross-sectional survey and semi-structured interviews. Data collected were analyzed using reflexive thematic analysis, which was informed by the Areas of Worklife Model.ResultsOverall, 28 unique surgeons participated in this study; 11 surgeons participated in interviews and 22 provided responses through the survey. Significant contributors to burnout identified included difficulties providing adequate care to patients due to limited resources and time available in academic medical centers and the moral injury associated with these challenges. The inequitable remuneration associated with education, administration, and leadership roles as a result of the Fee-For-Service model, as well as issues of gender inequity and the individualistic culture prevalent in surgical specialties were also described as contributing factors. Participants suggested increasing engagement between hospital leadership and staff to ensure surgeons are able to access resources to care for their patients, reforming payment plans and workplace polities to address issues of inequity, and improving workplace social dynamics as strategies for addressing burnout.DiscussionThe high prevalence and negative sequalae of burnout in surgery necessitates the formation of targeted interventions to address this issue. A collaborative approach to developing interventions to improve burnout among surgeons may lead to feasible and sustainable solutions.
