Pathophysiology of cerebral small vessel disease: a journey through recent discoveries.

Cerebral small vessel disease (cSVD) encompasses a heterogeneous group of age-related small vessel pathologies that affect multiple regions. Disease manifestations range from lesions incidentally detected on neuroimaging (white matter hyperintensities, small deep infarcts, microbleeds, or enlarged perivascular spaces) to severe disability and cognitive impairment. cSVD accounts for approximately 25% of ischemic strokes and the vast majority of spontaneous intracerebral hemorrhage and is also the most important vascular contributor to dementia. Despite its high prevalence and potentially long therapeutic window, there are still no mechanism-based treatments. Here, we provide an overview of the recent advances in this field. We summarize recent data highlighting the remarkable continuum between monogenic and multifactorial cSVDs involving NOTCH3, HTRA1, and COL4A1/A2 genes. Taking a vessel-centric view, we discuss possible cause-and-effect relationships between risk factors, structural and functional vessel changes, and disease manifestations, underscoring some major knowledge gaps. Although endothelial dysfunction is rightly considered a central feature of cSVD, the contributions of smooth muscle cells, pericytes, and other perivascular cells warrant continued investigation.

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.

Assessing Tobacco Treatment Engagement in Assertive Community Treatment Programs.

Despite high tobacco use prevalence among those with serious mental illnesses, few Assertive Community Treatment (ACT) programs provide tobacco treatment. Understanding the factors associated with the intentions to engage in tobacco treatment from both provider and consumer perspectives is important. The purpose was to examine ACT providers' intention to provide and consumer intention to engage in tobacco treatment. A cross-sectional survey of ACT program providers (N = 51) and consumers (N = 43) from four community mental health centers. Multiple linear regression analyses were used to examine factors associated with the intentions to provide or engage in tobacco treatment from among attitudinal, subjective norms, and perceived behavioral control variables. Providers reported positive attitudes, high degree of perceived behavior control, and high intentions for delivering tobacco treatment, but poor perceptions of subjective norms. These results were like consumers' intentions to engage in tobacco treatment. In regression analysis, only subjective norms and perceived behavior control were significant predictors for providers' intentions to provide tobacco treatment, but there were no significant predictors of consumers' intentions to engage in tobacco treatment. Both providers and consumers endorsed poor implementation of evidence-based tobacco treatment. Poor engagement in tobacco treatment within ACT programs indicates the need for policymakers to support tobacco treatment within the services. This finding calls for training of mental and behavioral health providers while supporting tobacco-free initiatives in ACT treatment service settings.

WTAP promotes proliferation of esophageal squamous cell carcinoma via m6A-dependent epigenetic promoting of PTP4A1.

Esophageal squamous cell carcinoma (ESCC) represents a frequently seen malignancy with high prevalence worldwide. Although current studies have shown that Wilms' tumor 1-associated protein (WTAP), a major part in the methyltransferase complex, is involved in various tumor pathological processes, its specific role in ESCC remains unclear. Therefore, the present work focused on exploring WTAP's function and mechanism in ESCC progression using clinical ESCC specimens, ESCC cells, and mammalian models. Firstly, we proved WTAP was significantly upregulated within ESCC, and WTAP mRNA expression showed a good diagnostic performance for ESCC. Functionally, WTAP positively regulated in-vivo and in-vitro ESCC cells' malignant phenotype through the AKT-mTOR signaling pathway. Meanwhile, WTAP positively regulated the N6-methyladenosine (m6A) modification levels in ESCC cells. Protein tyrosine phase type IVA member 1 (PTP4A1) was confirmed to be the m6A target of WTAP, and WTAP positively regulated the expression of PTP4A1. Further study revealed that PTP4A1 showed high expression within ESCC. Silencing PTP4A1 inhibited the AKT-mTOR signaling pathway to suppress ESCC cells' proliferation. Rescue experiments showed that silencing PTP4A1 partially reversed the WTAP-promoting effect on ESCC cells' proliferation ability. Mechanistically, WTAP regulated PTP4A1 expression to activate the AKT-mTOR pathway, promoting the proliferation of ESCC cells. Our study demonstrated that WTAP regulates the progression of ESCC through the m6A-PTP4A1-AKT-mTOR signaling axis and that WTAP is a potential target for diagnosing and treating ESCC.

High prevalence of gastrointestinal disorders in a large cohort of patients with joint hypermobility.

The gastrointestinal (GI) manifestations in children with hypermobile Ehlers-Danlos syndrome/joint hypermobility syndrome (hEDS/JHS) are not well described. We investigated the prevalence of GI disorders in children and young adults with hEDS/JHS through a single-center retrospective review. Demographic data, clinical history, symptoms, and diagnostic studies were reviewed. Of 435 patients with hEDS/JHS, 66% were females (age 5-28 years). We noted a high prevalence of constipation (61%), dysphagia (32%), dyspepsia and/or gastroparesis (25%), eosinophilic esophagitis (EoE) (21%), and celiac disease (4%) in our cohort. Upper endoscopy and gastric emptying scans had the highest yield to detect abnormalities. Motility studies were abnormal in 31% of the 80 patients who underwent them. Dysphagia symptoms are significantly associated with EoE. Thirty-three percent of dysphagia patients had EoE, versus 16%of non-dysphagia patients (p < 0.001). Screening hEDS/JHS patients for GI issues should be routine, with further investigations and referrals guided by identified symptoms.

Prevalence of non-communicable disease risk factors among nursing staff in a low and middle-income country: A cross-sectional digital survey-based study.

To assess the prevalence of non-communicable disease risk factors among the nursing staff and educate them on prevention. Nursing staff is integral to the Indian community healthcare systems. Recent studies report a high prevalence of non-communicable diseases in Indian nursing staff. Therefore, data on the prevalence of non-communicable disease risk factors among nursing staff are crucial for education on prevention. A cross-sectional digital survey-based study. We invited 4435 nursing staff to attend our online survey. We used a customized questionnaire for data collection, including a digitized version of the Community-Based Assessment Checklist form. A score of >4 was considered high risk and warranted screening. Among 682 nursing staff who attended, 70% had never undergone screening for non-communicable diseases. The prevalence of non-communicable disease risk factors was significantly higher in male nursing staff. In addition, logistic regression analysis showed that age, tobacco and alcohol use, increased waist circumference, physical inactivity and family history of non-communicable diseases were significant risk factors among nursing staff. The study findings suggest that the nursing staff have suboptimal self-health concerns on non-communicable diseases. This situation warrants continued medical education, awareness campaigns on adopting a healthy lifestyle and health promotion.

Reducing Commercial Tobacco Sales to Youth On and Around California Tribal Reservations with a Reward and Reminder Retail Intervention.

High prevalence of commercial tobacco product (CTP) use among American Indian and Alaska Native (AI/AN) youth is a public health crisis. A multi-level Tribal-community-based participatory research project under Tribal public health authority implemented a retailer-focused intervention to reduce AI/AN youth CTP use. We sought resolutions in support of a retailer-focused CTP intervention from Tribal Nations organized by a tribally-directed research program. We identified tobacco retail outlets operating on and within 5 miles of 9 Tribal reservations, and CTP products sold at these outlets. We conducted a four-wave Reward and Reminder intervention with apparent minor buyers. Clerks who complied with the law received a modest reward and commendation in social media posts to the local Tribal communities, while clerks who sold without age verification were reminded of the laws. Of 18 retail outlets selling CTP, 8 sold e-cigarettes, and all sold combustible cigarettes. The Reward and Reminder intervention showed an approximate 25% reduction in sales of CTP to apparent minors, with a 33% baseline CTP sales rate without age verification and an 8% intervention CTP sales rate without age verification. The intervention increased awareness of laws prohibiting CTP sales to minors and mandating age verification for young adults seeking to buy CTP. The intervention, which had support from all governing Tribal Nations, builds the evidence base of effective practices which Tribal public health authorities may utilize to reduce youth access to CTP on and around Tribal reservations. Sovereign Tribes have authority over commercial businesses operating on their lands. Tobacco 21 laws aiming to restrict commercial tobacco availability to youth are supported by Tribes. A retailer intervention in which apparent minors attempt commercial tobacco purchases can offer accountability feedback to retailers both on and near Tribal reservations. Obtaining Tribal support and publicizing the interventions helps mobilize Tribal communities to support commercial tobacco prevention and promote healthy youth.

Design and Validation of Primer Sets for the Detection and Quantification of Antibiotic Resistance Genes in Environmental Samples by Quantitative PCR.

The high prevalence of antibiotic resistant bacteria (ARB) in several environments is a great concern threatening human health. Particularly, wastewater treatment plants (WWTP) become important contributors to the dissemination of ARB to receiving water bodies, due to the inefficient management or treatment of highly antibiotic-concentrated wastewaters. Hence, it is vital to develop molecular tools that allow proper monitoring of the genes encoding resistances to these important therapeutic compounds (antibiotic resistant genes, ARGs). For an accurate quantification of ARGs, there is a need for sensitive and robust qPCR assays supported by a good design of primers and validated protocols. In this study, eleven relevant ARGs were selected as targets, including aadA and aadB (conferring resistance to aminoglycosides); ampC, blaTEM, blaSHV, and mecA (resistance to beta-lactams); dfrA1 (resistance to trimethoprim); ermB (resistance to macrolides); fosA (resistance to fosfomycin); qnrS (resistance to quinolones); and tetA(A) (resistance to tetracyclines). The in silico design of the new primer sets was performed based on the alignment of all the sequences of the target ARGs (orthology grade > 70%) deposited in the Kyoto Encyclopedia of Genes and Genomes (KEGG) database, allowing higher coverages of the ARGs' biodiversity than those of several primers described to date. The adequate design and performance of the new molecular tools were validated in six samples, retrieved from both natural and engineered environments related to wastewater treatment. The hallmarks of the optimized qPCR assays were high amplification efficiency (> 90%), good linearity of the standard curve (R2 > 0.980), repeatability and reproducibility across experiments, and a wide linear dynamic range. The new primer sets and methodology described here are valuable tools to upgrade the monitorization of the abundance and emergence of the targeted ARGs by qPCR in WWTPs and related environments.

Association of type 2 diabetes with family history of diabetes, diabetes biomarkers, mental and physical disorders in a Kenyan setting

This study aimed to determine the degree of family relations and associated socio-demographics characteristics, clinical/physical and mental disorders in type 2 diabetes mellitus in a Kenyan diabetes clinic. This study was part of a large multicentre study whose protocol and results had been published. It took place at the outpatient diabetes clinic at a County Teaching and Referral Hospital in South East Kenya involving 182 participants. We used a socio-demographic questionnaire, the Hamilton Depression (HAM-D) and PHQ-9 rating scales for depression, the MINI International Neuropsychiatric Interview (MINI; V5 or V6) for DSM-5 diagnoses, the WHO-5 Well-being scale and Problem Areas in Diabetes Scale (PAID). We extracted from the notes all physical conditions. We enquired about similar conditions in 1st and 2nd degree relatives. Descriptive, Chi-square test, Fisher’s exact test, one way ANOVA, and Multinomial logistic regression analysis were conducted to test achievements of our specific aims. Of the 182 patients who participated in the study, 45.1% (82/182) reported a family history of diabetes. Conditions significantly (p < 0.05) associated with a degree of family history of diabetes were retinopathy, duration of diabetes (years), hypertension, and depressive disorder. On average 11.5% (21/182) scored severe depression (≥ 10) on PHQ-9 and 85.2% (115/182) scored good well-being (≥ 13 points). All DSM-5 psychiatric conditions were found in the 182 patients in varying prevalence regardless of relations. In addition, amongst the 182 patients, the highest prevalence was poor well-being on the WHO quality of life tool. This was followed by post-traumatic disorders (current), suicidality, and psychotic lifetime on DSM-5. The least prevalent on DSM-5 was eating disorders. Some type 2 diabetes mellitus physical disorders and depression have increased incidence in closely related patients. Overall, for all the patients, the prevalence of all DSM-5 diagnoses varied from 0.5 to 9.9%.

Incidence of primary hepatitis C infection among people who inject drugs during 2012-2020 in Athens, Greece.

One of the World Health Organization's targets for the 2030 viral hepatitis elimination strategy is to reduce new hepatitis C (HCV) infections. In Athens, Greece, people who inject drugs (PWID) have a high HCV prevalence, with increasing trends since the 2000s. This analysis aims to assess primary HCV incidence among PWID during 2012-2020. Two community-based interventions were implemented in 2012-2013 and 2018-2020 with repeated sero-behavioural surveys in each period. Participants enrolled in multiple surveys were identified through linkage. To assess trends in HCV transmission, three indicators were estimated: (i) anti-HCV prevalence among 'new' injectors (those injecting ≤2 years), (ii) indirect HCV incidence among 'new' injectors, assuming infection occurred at the midpoint between initiating injection and the first positive test, and (iii) HCV incidence from repeat participants. There were 431 and 125 'new' injectors, respectively, in 2012-2013 and 2018-2020. Αnti-HCV prevalence [95% CI] declined from 53.6% [48.8%, 58.3%] in 2012-2013 to 40.0% [31.3, 49.1%] in 2018-2020 (25.4% reduction, p = .007). The indirect estimate [95% CI] of HCV incidence among 'new' injectors decreased from 56.1 [49.3, 63.8] to 39.0/100 person-years (PYs) [29.6, 51.5] (30.5% reduction, p = .020). HCV incidence [95% CI] based on seroconversions in repeat participants (16/63 in 2012-2013 and 9/55 in 2018-2020) declined from 64.6 [39.6105.4] to 13.8/100 PYs [7.2, 26.5], respectively (78.6% reduction, p < .001). Primary HCV incidence remains high among PWID in Athens. Consistent implementation of combined interventions, including high-coverage harm reduction programs and initiatives tailored to increase access to HCV treatment, is essential to sustain the declining trends documented during 2012-2020.

Pregnancy-related complications in patients with endometriosis in different stages

BackgroundEndometriosis is one of the most common and costly diseases among women. This study was carried out to investigate pregnancy outcomes in women with endometriosis because of the high prevalence of endometriosis in reproductive ages and its effect on pregnancy-related complications outcomes.MethodsThis was a cross-sectional study performed on 379 pregnant women with endometriosis who were referred to the endometriosis clinic of the Avicenna Infertility Treatment Center from 2014 to 2020. Maternal and neonatal outcomes were assessed for the endometriosis group and healthy mothers. The group with endometriosis was further divided into two groups: those who underwent surgery and those who either received medication alone or were left untreated before becoming pregnant. The analysis of the data was done using SPSS 18.ResultsThe mean age of the patients was 33.65 ± 7.9 years. The frequency of endometriosis stage (P = 0.622) and surgery (P = 0.400) in different age groups were not statistically significant. The highest rates of RIF and infertility were in stages 3 (N = 46, 17.2%) (P = 0.067), and 4 (N = 129, 48.3%) (P = 0.073), respectively, but these differences were not statistically different, and the highest rate of pregnancy with ART/spontaneous pregnancy was observed in stage 4 without significant differences (P = 0.259). Besides, the frequency of clinical/ectopic pregnancy and cesarean section was not statistically different across stages (P > 0.05). There is no significant relationship between endometriosis surgery and infertility (P = 0.089) and RIF (P = 0.232). Most of the people who had endometriosis surgery with assisted reproductive methods got pregnant, and this relationship was statistically significant (P = 0.002) in which 77.1% (N = 138) of ART and 63% (N = 264) of spontaneous pregnancies were reported in patients with endometriosis surgery. The rate of live births (59.4%) was not statistically significant for different endometriosis stages (P = 0.638). There was no stillbirth or neonatal death in this study. All cases with preeclampsia (N = 5) were reported in stage 4. 66.7% (N = 8) of the preterm labor was in stage 4 and 33.3% (N = 4) was in stage 3 (P = 0.005). Antepartum bleeding, antepartum hospital admission, preterm labor, gestational diabetes, gestational hypertension, abortion, placental complications and NICU admission were higher in stage 4, but this difference had no statistical difference.ConclusionEndometriosis is significantly correlated with infertility. The highest rates of RIF and infertility are observed in stages 3 and 4 of endometriosis. The rate of pregnancy with ART/spontaneous pregnancy, preterm labor, preeclampsia and pregnancy-related complications is higher in stage 4. Most of the people who had endometriosis surgery with assisted reproductive methods got significantly pregnant. Clinical/ectopic pregnancy, cesarean sections, and live birth were not affected by the endometriosis stages.

Prevalence, factors associated and management of needle phobia among the general population in Saudi Arabia and Egypt

ObjectiveThis study aims to assess the prevalence of needle phobia among Saudi and Egyptian adult populations. In addition, underlying causes and strategies that can be utilized to address needle fear were investigated.MethodsA cross-sectional online survey study was conducted in Saudi Arabia and Egypt between 1 May and 30 June 2023. Participants aged 18 years and above and living in Saudi Arabia and Egypt were eligible to complete the survey. Participants were invited to participate in this study through social media platforms (Facebook, X, Snapchat, and Instagram). A convenience sampling technique was used to recruit the study participants. A 21-item questionnaire consisting of four sections including a Likert scale score was used to answer the research objectives. Numeric data were presented as mean ± SD. For categorical variables, percentages were used. Comparison between groups were made by Student’s t-test or Mann Whitney test according to data distribution. Chi squared tests for categorical values were conducted. A binary logistic regression analysis was conducted to investigate factors associated with needle phobia.ResultsA total of 4065 participants were involved in this study (Saudi Arabia: 2628 and Egypt: 1437). Around one-third of the study participants (36.5%) confirmed that they have needle phobia. Most of the study participants (81.1%) reported that they have had needle phobia since they were under 18 years of age. Pain, general anxiety, and fear of making a mistake during the procedure were the most commonly reported contributors for fear of needles during or before a medical procedure. Around 15.8% of the study participants reported that they have tried to get rid of phobia from needles. Non-surgical alternatives (such as oral medications and patches) and using smaller/thinner needles were the most commonly reported interventions that reduced fear of needles. Binary logistic regression analysis identified that females, those who are aged (41–50 years), widowed, those with bachelor’s degrees and higher education, and those unemployed were more likely to have needle phobia compared to others.ConclusionOur study highlighted the high prevalence of needle fear within an adult population in Egypt and Saudi Arabia. Females, those who are aged (41–50 years), those widowed, those with higher education degrees, those unemployed, those working in the health sector and people with low income were more likely to have needle phobia compared to others.

Weight change in the first 30 days among infants born less than 2000 grams in Guinea-Bissau and Uganda

Despite the high prevalence of low birth weight infants in sub-Saharan Africa and the associated poor outcomes, weight change during the newborn period has not been well characterized for this population. We prospectively assessed growth over the first 30 days among 120 infants born < 2000 g (g) in Guinea‐Bissau and Uganda, and compared it to a similar cohort of 420 infants born ≥ 2000 g. Among those born < 2000 g, mean birth weight was 1747 ± 164 g, and initial weight loss was 8.25 ± 4.40% of birth weight prior to the initiation of weight gain at a median of 3 (interquartile range 2, 4) days of age. This initial weight loss was more pronounced (8.25 vs 6.06%; p < 0.001) and lasted longer (median 3 vs 2 days; p < 0.001) than for infants born ≥ 2000 g. The initial period of weight loss was an important predictor of growth at 30 days in both cohorts. Infants born < 2000 g on average grew proportionately to their size at birth but did not experience catch-up growth; their weights at 30 days remained much lower than that of infants born ≥ 2000 g and most remained severely underweight. Targeted interventions to optimize early growth should be investigated.

Safety and efficacy of monthly high-dose vitamin D3 supplementation in children and adolescents with sickle cell disease.

Little is known about the impact of vitamin D supplementation on hand grip strength (HGS) and health-related quality of life (HRQoL) in children and adolescents with sickle cell disease (SCD). We aimed to evaluate the safety and efficacy of monthly high-dose vitamin D3 supplementation and its implications on bone mineral density (BMD), HGS, and HRQoL in patients with SCD and healthy controls. The study included 42 children with SCD and 42 healthy matched controls. The study participants were supplemented with high-dose monthly oral vitamin D3. Changes in the serum level of 25(OH) vitamin D3, maximum HGS, and BMD from baseline to 6months were assessed, and the HRQoL questionnaire and Childhood Health Assessment Questionnaire (CHAQ) were used to evaluate the functional capacity. At baseline, SCD subjects had poorer growth status indicated by negative Z scores. Suboptimal BMD was detected by significantly lower Z score, and lower HGS and worse HRQL parameters were found compared to the controls (P < 0.001). Median 25(OH) vitamin D3 was significantly lower in SCD patients compared to controls (16.5 vs. 28ng/mL, respectively (P < 0.001)). After 6months of vitamin D supplementation, there was significant improvement in the DEXA Z-score (P < 0.001), limitation of physical health (P = 0.02), pain scores (P < 0.001), and CHAQ grades (P = 0.01) in SCD patients. A significant improvement in HGS (P < 0.001 and P = 0.005) as well as the CHAQ score (P < 0.001 and P = 0.003) was detected in the SCD group and controls, respectively. There were no reported clinical adverse events (AEs) or new concomitant medications (CMs) during the study duration, and safe levels of Ca and 25 (OH) D3 were observed at 3 and 6months for both groups. There was a significant positive correlation between HGS and total physical score (r = 0.831, P < 0.001) and a negative correlation with CHAQ score (r = - 0.685, P < 0.001). We also detected a significant positive correlation between vitamin D levels at 6months and HGS (r = 0.584, P < 0.001), pain score (r = 0.446, P < 0.001), and a negative correlation with CHAQ score (r = - 0.399, P < 0.001). Conclusion: Monthly oral high-dose vitamin D supplementation was safe and effective in improving vitamin D levels, HGS, and HRQoL in SCD children and healthy subjects, and BMD scores in SCD patients. Further randomized controlled trials are warranted to assess an optimal dosing strategy and to investigate the impact on clinically significant outcomes in children and adolescents with SCD and their healthy counterparts. Trial registration: ClinicalTrials.gov , identifier NCT06274203, date of registration: 23/02/2024, retrospectively registered. What is known: • Several studies have reported a high prevalence of vitamin D deficiency and suboptimal bone mineral density (BMD) in sickle cell disease (SCD) patients. • Musculoskeletal dysfunction is reported in SCD patients with a negative impact on physical activity and health-related quality of life (HRQL). • Little is known regarding the impact of vitamin D3 supplementation in children and adolescents with SCD. What is new: • We found that monthly oral high-dose vitamin D3 supplementation was safe, tolerated, and effective in improving serum vitamin D levels, HGS, BMD scores, and HRQL in SCD patients.

High Prevalence of Unconfirmed Positive HIV PCR Test Results among African Infants with HIV Exposure in the International epidemiology Databases to Evaluate AIDS (IeDEA) Consortium.

In a large, multi-regional cohort of African infants with HIV exposure, 44% of those with a positive HIV PCR lacked a confirmatory positive test. Efforts are needed to ensure high-fidelity implementation of HIV testing algorithms, so that all positive results are confirmed thereby reducing the risk of potentially false-positive results.

Polyvascular Disease: A Narrative Review of Risk Factors, Clinical Outcomes and Treatment.

Polyvascular disease has a significant global burden and is associated with increased risk of major adverse cardiac events with each additional vascular territory involved. The purpose of this review is to highlight the risk factors, associated outcomes, emerging genetic markers, and evidence for screening and treatment of polyvascular disease. Polyvascular disease is the presence of atherosclerosis in two or more vascular beds. It has a significant global burden, with a prevalence of 30-70% in patients with known atherosclerosis. Patients with polyvascular disease experience elevated rates of cardiovascular death, myocardial infarction and stroke, especially among high-risk subgroups like those with type 2 diabetes mellitus and there is a step-wise increased risk of adverse outcomes with each additional vascular territory involved. Genetic analyses demonstrate that some individuals may carry a genetic predisposition, while others exhibit higher levels of atherogenic lipoproteins and inflammatory markers. Routine screening for asymptomatic disease is not currently recommended by major cardiovascular societies unless patients are high-risk. While there are no established protocols for escalating treatment, existing guidelines advocate for lipid-lowering therapy. Additionally, recent studies have demonstrated benefit from antithrombotic agents, such as P2Y12 inhibitors and low-dose anticoagulation, but the optimal timing and dosage of these agents has not been established, and the ischemic benefit must be balanced against the increased risk of bleeding in the polyvascular population. Due to the high prevalence and risks associated with polyvascular disease, early identification and treatment intensification are crucial to reduce disease progression. Future research is needed to develop screening protocols and determine the optimal timing and dosing of therapy to prevent ischemic events.

Quality and safety actions in primary care practices in COVID-19 pandemic: the PRICOV-19 study in Spain

BackgroundPrimary Health Care (PHC) has been key element in detection, monitoring and treatment of COVID-19 cases in Spain. We describe how PHC practices (PCPs) organized healthcare to guarantee quality and safety and, if there were differences among the 17 Spanish regions according to the COVID-19 prevalence.MethodsCross-sectional study through the PRICOV-19 European Online Survey in PCPs in Spain. The questionnaire included structure and process items per PCP. Data collection was due from January to May 2021. A descriptive and comparative analysis and a logistic regression model were performed to identify differences among regions by COVID-19 prevalence (low < 5% or high ≥5%).ResultsTwo hundred sixty-six PCPs answered. 83.8% of PCPs were in high prevalence regions. Over 70% PCPs were multi-professional teams. PCPs attended mainly elderly (60.9%) and chronic patients (53.0%). Regarding structure indicators, no differences by prevalence detected. In 77.1% of PCPs administrative staff were more involved in providing recommendations. Only 53% of PCPs had a phone protocol although 73% of administrative staff participated in phone triage. High prevalence regions offered remote assessment (20.4% vs 2.3%, p 0.004) and online platforms to download administrative documents more frequently than low prevalence (30% vs 4.7%, p < 0.001).More backup staff members were hired by health authorities in high prevalence regions, especially nurses (63.9% vs 37.8%, p < 0.001. OR:4.20 (1.01-8.71)). 63.5% of PCPs provided proactive care for chronic patients. 41.0% of PCPs recognized that patients with serious conditions did not know to get an appointment.Urgent conditions suffered delayed care in 79.1% of PCPs in low prevalence compared to 65.9% in high prevalence regions (p 0.240). A 68% of PCPs agreed on having inadequate support from the government to provide proper functioning. 61% of high prevalence PCPs and 69.5% of low ones (p: 0.036) perceived as positive the role of governmental guidelines for management of COVID-19.ConclusionsSpanish PCPs shared a basic standardized PCPs’ structure and common clinical procedures due to the centralization of public health authority in the pandemic. Therefore, no relevant differences in safety and quality of care between regions with high and low prevalence were detected. Nurses and administrative staff were hired efficiently in response to the pandemic. Delay in care happened in patients with serious conditions and little follow-up for mental health and intimate partner violence affected patients was identified. Nevertheless, proactive care was offered for chronic patients in most of the PCPs.

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.

Trematode infection in ruminants and diversity of snail hosts across three agro-ecological zones in Ethiopia

The occurrence of trematodes among ruminants and their snail vectors is a major concern across various agro-ecological regions of Ethiopia. Trematodes pose significant threats to animals, causing considerable economic losses and impacting public health. In this study, we have investigated 784 ruminant fecal samples, and 520 abattoir samples, alongside the collection and identification of snail vectors from various agro-ecological regions. Fecal examinations revealed Fasciola, Paramphistomum and Schistosoma species infected 20.5% (95% CI: 17.6, 23.8), 11.7% (95% CI: 9.6, 14.2), and 6.3% (95% CI: 4.1, 9.1) of the animals, respectively. The overall prevalence of trematodes among ruminants was 28.8% (95% CI: 25.7, 32.1%), with 6.0% (95% CI: 4.3, 7.7) showing mixed infections. Fasciola was more prevalent in Asela (26%) compared to Batu (19%) and Hawassa (11.5%), while a higher proportion of animals in Batu were infected with Paramphistomum. Schistosoma eggs were detected only in Batu (12.5%), but not in other areas. Sheep and cattle exhibited higher infection rates with Fasciola, Paramphistoma, and Schistosoma compared to goats. Significant associations were observed between trematode infections and risk factors including agro-ecology, animal species, body condition score, and deworming practices. About 20.8% and 22.7% of the slaughtered animals harbored Fasciola and Paramphistomum flukes, respectively, with a higher prevalence in Asela and Hawassa abattoirs compared to Batu abattoir. Additionally, a total of 278 snails were collected from the study areas and identified as lymnae natalensis, lymnae trancatula, Biomphalaria pffiferi, Biomphlaria sudanica, and Bulinus globosus. In conclusion, the study highlights the widespread occurrence of trematode infections, emphasizing the need for feasible control measures to mitigate their economic and public health impacts.
