ObjectiveTo determine the association of epilepsy with incident dementia by conducting a nationwide, retrospective data-linkage, cohort study to examine whether the association varies according to dementia subtypes and to investigate whether risk factors modify the association.MethodsWe used linked health data from hospitalization, mortality records, and primary care consultations to follow up 563,151 Welsh residents from their 60th birthday to estimate dementia rate and associated risk factors. Dementia, epilepsy, and covariates (medication, smoking, comorbid conditions) were classified with the use of previously validated code lists. We studied rate of dementia and dementia subtypes in people with epilepsy (PWE) and without epilepsy using (stratified) Kaplan-Meier plots and flexible parametric survival models.ResultsPWE had a 2.5 (95% confidence interval [CI] 2.3–2.6) times higher hazard of incident dementia, a 1.6 (95% CI 1.4–1.8) times higher hazard of incident Alzheimer disease (AD), and a 3.1 (95% CI 2.8–3.4) times higher hazard of incident Vascular dementia (VaD). A history of stroke modified the increased incidence in PWE. PWE who were first diagnosed at ≤25 years of age had a dementia rate similar to that of those diagnosed later in life. PWE who had ever been prescribed sodium valproate compared to those who had not were at higher risk of dementia (hazard ratio [HR] 1.6, 99% CI 1.4–1.9) and VaD (HR 1.7, 99% CI 1.4–2.1) but not AD (HR 1.2, 99% CI 0.9–1.5).ConclusionPWE compared to those without epilepsy have an increased dementia risk.

BACKGROUND Hepatitis B and C virus (HBV and HCV) infections rank among the most frequent infectious diseases with a rising worldwide burden. However, their epidemiology and risk factors are understudied in many regions, including Iran. METHODS This study was conducted as part of the Pars Cohort Study (PCS) in Valashahr district, Fars province (2012-2014). Participants received venipuncture for HBsAg and HCV antibody, followed by Polymerase Chain Reaction (PCR) testing. All infected people and their comparison groups completed a risk assessment questionnaire. RESULTS Overall, 9,269 people participated in the study; the majority were women and of Fars ethnicity. Prevalence of HBsAg and HCV antibody was 2.3% (n = 215) and 0.3% (n = 26), from whom 23% (n = 47) and 13% (n = 3) had indications for treatment, respectively. During follow-up, among HBsAg-positive individuals who were not on treatment, 62% tested negative for HBsAg, and in 2% HBV DNA had risen to treatment levels. Risk factors for HBV infection were illiteracy [OR = 3.43, 95% CI = 1.1, 10.3], and Turk ethnicity compared to Fars [OR = 1.58, 95% CI = 1.1, 2.3]. History of blood transfusion [OR = 2.00, 95% CI = 1.1, 3.5] and history of drug use [OR = 2.85, 95% CI = 1.1, 7.4] were associated with HCV infection, after adjustment. CONCLUSION Further epidemiological studies are needed to identify at-risk populations in different regions. Preventive interventions, including educational programs and transfusion safety strategies, are crucial for reducing the hepatitis burden.

Osseointegration of a dental implant may encounter a variety of problems caused by various factors, as prior health-related problems, patients� habits and the technique of the implant inserting. Retrospective cohort study of 70 patients who received implants between January 2011- April 2016 in one dental unit, with Kaplan-Meier method to calculate the probability of implants�s survival at 60 months. The analysis included demographic data, age, gender, medical history, behavior risk factors, type and location of the implant. For this cohort the implants�survival for the first 6 months was 92.86% compared to the number of patients and 97.56% compared to the number of total implants performed, with a cumulative failure rate of 2.43% after 60 months. Failures were focused exclusively on posterior mandible implants, on the percentage of 6.17%, odds ratio (OR) for these failures being 16.76 (P = 0.05) compared with other localisations of implants, exclusively in men with median age of 42 years.

BackgroundMaternal depression in the pre- and postpartum period may set women on a course of chronic depressive symptoms. Little is known about predictors of persistently elevated depressive symptoms in mothers from pregnancy onwards. The aims of this study are to determine maternal depression trajectories from pregnancy to the child's fifth birthday and identify associated risk factors.MethodMothers (N = 1807) from the EDEN mother–child birth cohort study based in France (2003–2011) were followed from 24–28 weeks of pregnancy to their child's fifth birthday. Maternal depression trajectories were determined with a semi-parametric group-based modelling strategy. Sociodemographic, psychosocial and psychiatric predictors were explored for their association with trajectory class membership.ResultsFive trajectories of maternal symptoms of depression from pregnancy onwards were identified: no symptoms (60.2%); persistent intermediate-level depressive symptoms (25.2%); persistent high depressive symptoms (5.0%); high symptoms in pregnancy only (4.7%); high symptoms in the child's preschool period only (4.9%).Socio-demographic predictorsassociated with persistent depression were non-French origin;psychosocial predictorswere childhood adversities, life events during pregnancy and work overinvestment;psychiatric predictorswere previous mental health problems, psychological help, and high anxiety during pregnancy.ConclusionsPersistent depression in mothers of young children is associated to several risk factors present prior to or during pregnancy, notably anxiety. These characteristics precede depression trajectories and offer a possible entry point to enhance mother's mental health and reduce its burden on children.

Background Stroke not only substantially increases the risk of incident dementia early after stroke, the risk remains elevated years after. Aim We aimed to determine the risk factors of dementia onset more than 3-6 months after stroke or transient ischemic attack (TIA). Methods This is a single center prospective cohort study. We recruited consecutive subjects with stroke/TIA without early-onset dementia. We conducted an annual neuropsychological assessment for 5 years. We investigated the association between baseline demographic, clinical, genetic (APOEε4 allele), and radiological factors, as well as incident recurrent stroke, with delayed-onset dementia using Cox proportional hazards models. Results 1,007 patients were recruited, of which 88 with early-onset dementia and 162 who lost to follow-ups were excluded. 49 (6.5%) out of 757 patients have incident delayed-onset dementia. The presence of ≥ 3 lacunes, history of ischemic heart disease (IHD), history of ischemic stroke and a lower baseline Hong Kong version of the Montreal Cognitive Assessment (MoCA) score, were significantly associated with delayed-onset dementia. APOEε4 allele, medial temporal lobe atrophy, and recurrent stroke were not predictive. Conclusion The presence of ≥ 3 lacunes, history of IHD, history of ischemic stroke and a lower baseline MoCA score, are associated with delayed-onset dementia after stroke/TIA.

Objective: To find out the pattern of CHD and associated risk factors among children presenting at a tertiary care hospital. Study Design: A case-control study. Place and Duration of the Study: The Department of Pediatrics and Department of Cardiology, Sheikh Khalifa Bin Zayed Al Nahyan Hospital, Rawlakot from July 2020 to June 2021. Material and Methods: A total of 207 children of both genders, screened by ECG along with chest x-ray and further confirmed with the diagnosis of CHD through echocardiography were enrolled as cases. Same number of healthy controls (n=207) were recruited from immunization center of the study institution. Among cases, types of CHD were noted. For cases and controls, demographic, antenatal and maternal risk factors including maternal age, gender of the child, history of consanguinity, history of febrile illness in pregnancy, use or multi-vitamin or folic acid in pregnancy, bad obstetrical history and maternal diabetes mellitus were noted. Results: In a total of 414 children (207 cases and 207 controls), there were 219 (53.8%) male. In terms of CHD types among cases, VSD was the most noted in 62 (30.0%), ASD 35 (16.9%), TOF 33 (15.9%) and PDA in 30 (14.5%). Cases were found to have significant association with younger age (78.3% cases below 1 year of age vs. 64.7% in controls, p=0.0085), bad obstetrical history (p=0.0002), history of febrile illness in 1st trimester of pregnancy (p=0.0229) and lack of multivitamins and folic acid in the 1st trimester of pregnancy (p=0.0147). Conclusion: Majority of the children with CHDs were male and aged below 1 year. VSD, ASD, TOF and PDA were the most frequent types of CHD. Younger age, bad obstetrical history, history of febrile illness in 1st trimester of pregnancy and lack of multivitamins and folic acid in the 1st trimester of pregnancy were found to have significant association with CHDs among children.

AbstractIntroductionPostnatal Depression (PND) is a major health problem affecting mother, her child and family.  Its prevalence and associated risk factors among South Asian mothers (SAM) living  in Qatar remain unknown. The objectives of this study were to estimate the prevalence of PND among (SEAM) in Qatar and to correlate risk factors contributing to the development of PND.Materials and methodsA total of (285 ) (SAM)females who were six months  postpartum were interviewed as  part of a prospective study conducted in primary health care centers in Qatar.  PND symptoms were defined as present when subjects had an Edinburgh Postnatal Depression Scale score of 10 or higher. Descriptive statistics were used for summarizing the study and outcome variables. The χ2 test and ORs with 95% confidence intervals (CIs) were used for observation and quantifying the association between different variables. Multivariate binary logistic regression was used to identify the independent associated factors of PPD. P≤0.05 was considered significant. Variables included were age , occupation, education level ,previous psychiatric history ,comorbidities , ,history of depression during current  pregnancy, history of anxiety during current pregnancy, number of previous pregnancies, strong social support, husband support, marital problem before pregnancy and ongoing marital problems during current pregnancy.Results The prevalence of postnatal depression among 285 respondents was 33.2% .several psychosocial risk factors were significantly associated with postnatal depression and, after multiple regression analysis, a history of depressive illness ,anxiety ,marital problems before delivery ,a history of diabetes and asthma ,history of congenital malformations ,and lack of mother support.Other variables, including age, parity, education, occupation, and delivery type, were not significantly correlated (P=0.15–0.95), but marginally indicative of the risk of depressive symptoms.ConclusionThis study showed a high rate of depressive symptoms among(SAM) six months Postpartum . Future screening protocols  must be employed at primary care level and hospital based clinics in Qatar to detect and treat post natal depression.Keywords: postnatal  depression,  South Asians, primary health care ,Doha, EPDS

Abstract Background HIV-associated non-AIDS (HANA) conditions are becoming common as People Living with Human Immunodeficiency Virus (PLWHIV) age. However, data estimating the prevalence of HANA conditions and associated risk factors is lacking in developing countries. This study evaluates reasons for hospitalizations among PLWHIV in Udupi, India in the antiretroviral era, and describes associated risk factors. Methods Demographic and clinical data were extracted from medical charts of 1280 HIV-infected patients 18 years and older who were admitted to Kasturba Hospital, Manipal, India between January 1, 2013 and December 31, 2017, for a total of 2157 hospitalizations. Primary reasons for hospitalization were categorized into AIDS-defining vs Non-AIDS-defining and HANA vs Non-HANA conditions (Fig 1). Multivariate logistic regression analysis was performed to estimate demographic and clinical factors associated with hospitalizations due to AIDS-defining illness and HANA conditions. Categorization of Reasons for Hospitalization Results Patients’ median age was 45 (18-80) years; 70% male. Median age of patients with AIDS-defining illness (45% of hospitalizations) was lower at 44 (18-75) years compared with HANA (15% of hospitalizations) at 48 (21-80) years. Age (OR, 95% CI) (0.985, 0.974-0.995), admission CD4 (0.998, 0.997 - 0.998), history of hypertension (HTN) (0.59, 0.42-0.82), stroke (0.49, 0.24 - 0.93), diabetes (1.56, 1.10 - 2.19), and AIDS-defining cancers (1.74, 1.05 - 2.89) were associated with AIDS-defining hospitalizations (Fig 2). Additionally, age (1.016, 1.001 - 1.031), history of HTN (1.70, 1.16 - 2.46), coronary artery disease (CAD) (4.02, 1.87- 9.02), chronic kidney disease (CKD) (2.30, 1.15 - 4.61), stroke (2.93, 1.46 - 5.96), Hepatitis B (3.32, 1.66- 6.72), Hepatitis C (16.1, 2.84 - 314), sexually transmitted disease (STD) (3.76, 1.38- 10.8), and HANA-associated cancer (2.44, 1.28- 6.42) were associated with HANA hospitalizations (Fig 3). Patient Risk Factors for AIDS-related Hospitalization Patient Risk Factors for HANA-related Hospitalization Conclusion Prevalence of HANA conditions was lower than AIDS-defining illnesses possibly because of a younger population. Patients with AIDS-defining illnesses were also likely to have HANA conditions. Early detection and effective treatment of both HIV and HANA conditions is essential to decrease hospitalizations in low-resource settings. Disclosures All Authors: No reported disclosures
