Objectives. To assess the probable risk factors associated with Multiple sclerosis among Syrian patients in the city of Damascus. Method. In a case-control study conducted from May to September 2020, 140 MS patients and 140 healthy controls were selected from two main hospitals in Damascus. Data regarding risk factors associated with MS was collected via a structured questionnaire and complementary laboratory tests. The statistical analysis was carried out by the SPSS Statistical Software Version 26. Results. Factors such as smoking, family history of MS, migraine, and vitamin D deficiency were associated with a higher risk of developing MS: Smoking ( OR = 2.275 95% CI (1.348-3.841) P = 0.002 ). Family history of MS ( OR = 3.970 95% CI (1.807-8.719) P ≤ 0.001 ). Migraine ( OR = 3.011 95% CI (1.345-6.741) P = 0.005 ). Vitamin D deficiency ( OR = 4.778 95% CI (2.863-7.972) P ≤ 0.001 ). However, factors such as diabetes, hypertension, a surgical history of appendectomy, tonsillectomy, and being the first-born in a family were statistically irrelevant: Diabetes ( OR = 0.652 95% CI (0.226-1.882) P = 0.426 ). Hypertension ( OR = 1.445 95% CI (0.724-2.885) P = 0.295 ) Appendectomy ( OR = 1.269 95% CI (0.486-3.317) P = 0.626 ) Tonsillectomy ( OR = 1.280 95% CI (0.576-2.843) P = 0.544 ). First-born Child ( OR = 0.933 95% CI (0.558-1.562) P = 0.793 ). Conclusion. Our study suggests that smoking, vitamin D deficiency, family history of MS, and migraine are probable risk factors for multiple sclerosis. Therefore, engaging in outdoor activities and maintaining a healthy diet—for females in particular—is highly recommended.

Abstract Background The incidence of systemic hypertension (HTN) among perinatally-HIV-infected (PHIV) patients appears to increase as they enter adulthood. Among non-perinatally HIV-infected adults both traditional and HIV-associated risk factors have been found to contribute to HTN. Whether these same factors contribute to HTN in PHIV is unknown. The purpose of this study was to determine the socio-demographic, clinical, virologic, and immunologic factors associated with HTN among a cohort of PHIV adolescents and young adults, aged ≥18 years. Methods We conducted a case–control study among a population of 160 PHIV adults with and without HTN who were receiving care at the University of Maryland and aged 18–35 years as of December 31, 2017. Covariates assessed included traditional risk factors such as age, family history of HTN, and smoking, as well as HIV- and antiretroviral-associated covariates. Results We identified 49 HTN cases (30.6%) and 111 (69.4%) controls. There were no significant differences in the odds of most traditional (age, gender, race, family history of HTN, tobacco, alcohol, and/or other drug use) or HIV-associated (CD4 nadir <100 cells/mm3, individual ART exposure, ART interruption) risk factors among PHIV adults with HTN compared with those with no diagnosis of HTN. Cases had lower odds of a history of treatment with lopinavir/ritonavir (LPV/r). Cases had 3.7 (95% CI 1.11, 12.56) times the odds of a prior diagnosis of chronic kidney disease (CKD) compared with controls after controlling for CD4 nadir and ARV treatment history. Conclusion The results of this study suggest that most traditional and HIV-related risk factors do not appear to increase the odds of having HTN in this PHIV cohort. However, HTN among PHIV may be driven in part by CKD, and a focus on the prevention and early management of CKD in this group may be necessary to prevent the development of HTN. Additionally, there may be as yet unidentified risk factors for HTN among PHIV which require further exploration. Given the large and growing population of PHIV entering adulthood worldwide, it is imperative to explore risk factors for and effects of HTN in large, diverse PHIV populations.

Abstract Background Genetic and environmental factors seem to have etiologic roles in multiple sclerosis (MS). Kuwait is regarded as medium to high risk country for MS. However, there is a paucity of published data on the risk factors for MS in Kuwait. Therefore, this matched case-control study examined the association between various factors including family history, stressful life events, exposure to tobacco smoke, vaccination history, comorbidities and MS risk in Kuwait. Methods Confirmed 110 MS cases and age (± 5 years), gender and nationality matched controls (1:1) were enrolled. A pre-tested structured questionnaire was used to collect the data through face-to-face interviews both from cases and controls. Conditional logistic regression was used to analyze the data. Results Among both cases and controls, majority were Kuwaiti (82.7%), and female (76.4%). Multivariable model showed that cases compared to controls were significantly more likely to have had a family history of MS (adjusted matched odds ratio (mORadj) = 5.1; 95% CI: 2.1–12.4; p < 0.001) or less likely to have been vaccinated against influenza A and B viruses before MS onset (mORadj = 0.4; 95% CI: 0.2–0.8; p = 0.010). None of the other variables considered were significantly related to MS status in this study. Conclusions Family history of MS had significantly direct, whereas, vaccination against influenza A and B viruses had inverse associations with MS status. Future studies may contemplate to verify the observed results.

Objective: The aim of this study was to determine the risk factors associated with early childhood caries (ECC).Methods: It was an observational retrospective case-control study. The case group consisted of all patients diagnosed with ECC in the records of an active program of maternal and child care. The control group was composed of an equal number of children, matched for gender and age, who attended the program and did not have ECC. The process of data collection consisted of completing a pre-established schedule to analyse variables related to the mother/caregiver and child.Statisticalanalysis was performed using the chi-squared and odds ratio (OR), with alpha (α) = 0.05.Results: History of caries in the mother (OR=2.61; CI 95%=1.45-4.67) and father (OR=1.72; CI 95%=1.02-2.89) were key determinants in the child being diagnosed with ECC.Conclusions: The risk factors associated with ECC were the following: no oral hygiene acceptance, nocturnal feeding duration of more than 16 months, a daily intake of sugar greater than 4 times a day, a Baume type II maxillary arch, fewer than 3 consultations with the program, and a history of decay in the parents.

Background: Diabetic neuropathy is one among the most common complication in diabetes mellitus. Diabetic peripheral neuropathy hinders the quality of life causing morbidity and mortality. The purpose of this study was to find the risk factors associated with diabetic neuropathy.Methods: This case control study involved 100 diabetic patients attending the Dohnavur fellowship hospital, Dohnavur from October 2019 to March 2020. Sociodemographic profile and diabetic characteristics of the study group were obtained and analysed. Diagnosis of Diabetic Neuropathy was done by using the diagnostic method proposed by American Diabetic Association.Results: Of the total study population with mean age 59.43 years, 63% had family history of diabetes. Almost 70% had poor diabetic control. Statistically significant relationships were found between neuropathy and duration of diabetes, glycaemic control, history of hypertension, monofilament test and pinprick sensation.Conclusions: In this study, glycemic control, dyslipidemia and hypertension were modifiable risk factors for diabetic neuropathy. Early interventional programs to sensitize diabetics on these factors could improve the quality of life of Diabetic patients.

Background: Numerous studies have assessed risk factors for multiple sclerosis (MS), although none have been conducted previously in Iran. Objective: The objective of this study was to study lifestyle and environmental risk factors of MS in the Iranian population. Methods: A case–control study, including 394 MS cases and 394 matched controls, was conducted in MS clinics in different Iranian cities. Information on lifestyles, environmental exposures, and past medical history was obtained from medical charts and phone interviews. Results: In multivariable analysis, sunlight exposure was associated with a lower risk of MS: the odds ratio (OR) and 95% confidence interval (CI) of MS associated with a 1-h increment in daily sunlight was 0.62 (0.53–0.73). Smoking was associated with MS risk in women (OR: 6.48, 95% CI: 1.46–28.78), but not in men (OR: 0.72, 95% CI: 0.31–1.68) ( p = 0.002 for interaction). Finally, past history of common surgical procedures, infectious disorders, or exposure to pets and farm animals was not associated with MS risk. Conclusions: Different modifiable lifestyles, including sunlight exposure and smoking, were associated with lower MS risk in Iran. Interventions aimed at promoting smoking cessation and, more importantly, at increasing exposure to sunlight might contribute to the prevention of MS.

Abstract Background Hypertension is the most common medical problem encountered in pregnancy and is a leading cause of perinatal and maternal morbidity and mortality. However, its magnitude and risk factors yet not adequately assessed at the study area. Methods Facility-based retrospective unmatched case-control study was conducted to identify risk factors associated with Hypertensive disorders of pregnancy in Nekemte Referral Hospital just two years back from study period July 1, 2015, to June 30, 2017. Bivariate logistic regression was considered for inclusion in to the multivariate logistic regression. Finally, multi varaite analysis were done to identify risk factors of hypertensive disorders of pregnancy. Results Among 6826 total delivery records from July 2015 –June 2017, 199 women developed hypertension during pregnancy. Among 199 women 153(76.9%) were pre-eclampsia/eclampsia,28(14.1%) were gestational hypertension, 14(0.7%) were superimposed hypertension and 4 (2.9%) were chronic hypertension. Age ≥ 35 (AOR: 2.51, 95% CI: 1.08, 5.83), rural residential area (AOR: 1.79, 95% CI: 1.150, 2.799), prim gravida (AOR: 3.39, 95% CI: 2.16, 5.33), null parity (AOR: 4.35, 95% CI: 2.36, 8.03), positive history of abortion (AOR: 4.39, 95% CI: 1.64, 11.76), twin pregnancy (AOR: 3.78, 95% CI: 1.52, 9.39), lack of ANC follow up (AOR: 3.05, 95% CI: 1.56, 5.96) as well as positive pre-existing hypertension (AOR: 3.81, 95% CI: 1.69, 8.58), positive family history of hypertension (AOR: 5.04, 95% CI: 2.66, 9.56) and positive history of diabetes mellitus (AOR: 5.03, 95% CI: 1.59, 15.89) were risk factors for hypertensive disorders during pregnancy. Conclusion This study found that Women with hypertension during pregnancy have a greater risk of developing adverse pregnancy outcome as compared to normotensive pregnant women. so, identification of these risk factors would be useful for early diagnosis of hypertension disorders during pregnancy to give appropriate clinical monitoring and treatments and timely managing maternal and perinatal complications.

An age-matched case-control study was initiated to determine the major risk factors associated with CKD in cats and dogs and to determine what clinical signs cat and dog owners observed before their veterinarian diagnosed their pet with CKD. When compared to controls, the feline cases were more likely to have had polydipsia and polyuria in the year before the owners' cats were diagnosed with CKD. In the dogs, increased water intake, increased urination, small size and a recent history of weight loss and bad breath were noticed by the dog owners before veterinary CKD diagnosis. Dog owners recognized abnormal drinking and urination behavior over half a year before their pet's veterinary diagnosis with CKD, and they recognized weight loss almost 4 months before CKD diagnosis. Bad breath was noticed 1.2 years before recognition of CKD by a veterinarian. Given that earlier CKD diagnosis should have been possible in most cases, clinical trials should proceed to measure the efficacy of early interventions.

Objectives. To assess whether there are shared exposures associated with Sjogren’s syndrome (SS), dry eye syndrome (DES), and B-cell non-Hodgkin lymphoma (B-NHL), in order to determine whether they are etiologically related. Methods. In a clinic-based case-control study, 702 participants (91 SS, 120 DES, 211 (age and sex frequency-matched) controls, and 280 B-NHL cases) were recruited and interviewed regarding exposures, medical history, and family history. Results. Female predominance was noted in SS (ratio 9.2 : 1). Eye dryness was severest in SS compared to DES and controls (P<0.001). Compared to controls, alcohol consumption was inversely associated with NHL, DES, and SS (odds ratio OR=0.47, 95% confidence interval (CI): 0.31-0.71; OR=0.54, 95% CI: 0.33-0.88; and OR=0.26, 95% CI: 0.14-0.49, respectively), while a previous history of infection requiring hospitalization was positively associated with all three conditions: NHL (OR=1.92; 95% CI: 1.23-2.99), DES (OR=3.29; 95% CI: 1.97-5.47), and SS (OR=4.74; 95% CI: 2.66-8.44). NHL patients were more likely to report first-degree relatives with hematologic cancer, while having first-degree relatives with an autoimmune disease (AID) was associated with SS (OR=5.25; 95% CI: 2.59-10.63) and DES (OR=3.55; 95% CI: 1.83-6.91) compared to controls. Conclusions. Some exposures are associated with all three conditions (such as an inverse association with alcohol consumption and a positive association with serious past infection), while a family history of AID appears to be shared by DES and SS, but not NHL subjects. Shared risk factors for all three conditions indicate possible mutual etiological pathways.
