A multistage, stratified random sample of 1312 students [aged 6-10 years] was selected from the five regions in Kuwait. Parents were interviewed and weight, height and urine analysis of the children were taken. Blood pressure was measured on at least three separate occasions. The overall prevalence of hypertension [average systolic and/or diastolic blood pressure > 95th percentile for age and sex] was 5.1%. In multivariate logistic regression analysis, certain groups of Kuwaiti schoolchildren were much more likely to develop hypertension. They included children whose parents were consanguineous, children with a family history of hypertension and obese children

Objective: To determine the relationship between childhood hypertension and family history of hypertension in primary school children in Port Harcourt.Methods: A stratified multi-staged sampling technique was used torecruit pupils between 6-12 years of age, from thirteen primary schoolslocated in three school districts. Data was collected using a pretestedquestionnaire completed by parents / guardians. The average of three blood pressure measurements, weight and height were taken for each pupil, using standardized techniques. Hypertension was defined as average systolic and / or diastolic blood pressure greater than or equalto the 95th percentile for age, gender and height using the standard bloodpressure charts. Family history of hypertension was defined as eitherparent indicating on the submitted questionnaire that they were hypertensive (diagnosed by a physician and/or on antihypertensive drugs)or had a family history of hypertension.Results: A total of 1302 pupils with 717 (55.1%) females and 585(44.9%) males were studied, giving a female to male ratio of 1.2:1. Themean age of pupils studied was 8.82±1.91 years. Sixty one (4.7%)of the pupils examined had hypertension. Of the 1302 pupils, 316(24.3%) had a family history of hypertension. The mean systolic(p<0.001) and diastolic (p=0.220) blood pressures were higher in childrenwith a family history of hypertension than in those without. Ofthe pupils that had a family history of hypertension, 7.9% had  hypertension, while 3.7% of those that did not have a family history, werefound to be hypertensive (p=0.001).Conclusion: A family history of hypertension was associated with a higher prevalence of childhood hypertension than was seen in children without a family history of hypertension.Key words: Childhood Hypertension, Family history.

Objective To examine the relation between the results of ambulatory 24-hour blood pressure monitoring (ABPM) and left ventricular mass index (LVMI), then to find the independent determinant for left ventricular hypertrophy (LVH) in peritoneal dialysis (PD) patients. Finally, to evaluate the differences in the clinical and cardiovascular characteristics between patients on continuous ambulatory PD (CAPD) and continuous cyclic PD (CCPD). Design An open, nonrandomized, cross-sectional study. Setting Divisions of nephrology and cardiology in a medical center. Patients Thirty-two uremic patients on maintenance PD therapy (22 patients on CAPD, and 10 on CCPD) without anatomical heart disease or history of receiving long-term hemodialysis. Interventions Home blood pressure (BP) and office BP were measured using the Korotkoff sound technique by sphygmomanometer. ABPM was employed for continuous measurement of BP. Echocardiography was performed for measurement of cardiac parameters and calculation of LVMI. Main Outcome Measures Multivariate logistic regression analysis was performed for independent determinant of LVH in PD patients. The differences in clinical and cardiovascular characteristics between CAPD and CCPD patients were compared. Results Simple regression analysis showed positive correlations between LVMI and the duration of hypertension, ambulatory nighttime BP/BP load/BP load > 30%, serum phosphate, calcium–phosphate product, ultrafiltration (UF) volume, and percentage of UF volume during the nighttime. A negative correlation was noted between LVMI and dipping. In multiple regression analysis, the duration of hypertension was the only variable linked to LVMI. In multivariate logistic regression analysis, only ambulatory nighttime systolic BP load > 30% had an independent association with LVH. There were correlations between office/home BP and ambulatory 24-hour BP. In addition, CCPD patients had higher LVMI, UF volume during the nighttime, and percentage of UF volume during the nighttime than those of CAPD patients. Conclusions In this study, ambulatory nighttime systolic BP load > 30% had an independent association with LVH. Office and home BP measurements were correlated with ABPM in PD patients. The result that CCPD patients had a higher LVMI than CAPD patients may be due to a relative volume overload during the daytime in CCPD patients.

Introduction: Pediculosis capitis has been a worldwide concern among the vulnerable population of primary school children due to the physical, economical and psychological consequences that it brings to both the children and their caretakers. It is observed that there were only limited studies conducted in Malaysia and no previous study was done in Kuantan despite the health concern that it bears. Since both local and worldwide studies show that  Pediculosis capitis  is more prevalent among female as compared to male school children, thus, this study aims to investigate the prevalence and predictors of  Pediculosis capitis  among female primary school children in Kuantan. Materials and method: An analytical crosssectional study using cluster random sampling was carried out in Kuantan, Pahang, Malaysia. A self-administered validated questionnaire was used to collect the data among female primary school children from standard one to six. Hair and scalp examination was performed to identify presence of  Pediculosis capitis  infestation. Multivariate logistic regression was used to control for potential confounding and determine the predictors  Results: 10 schools participated in the study with total number of 636 female students as respondents. The overall prevalence of  Pediculosis capitis among female primary school children was 17.6% (n=112). Multivariate logistic regression analysis showed that Indian (OR=5.634, 95% CI= 3.157-10.055), history of contact with infested person (OR=2.822, 95% CI=1.6193.691) and those who had number of family members more than four (OR=0.065, 95% CI=0.008-0.550) were predictors for  Pediculosis capitis Conclusion: The prevalence of  Pediculosis capitis  among female primary school children in Kuantan, Pahang is endemic (17.6%) and predictors are Indian, history of contact with infested person and having family members of more than 4. Hence, there is a need for health intervention to reduce the burden of  Pediculosis capitis  infestation.

Abstract Study question Does bariatric surgery (BS) decrease the occurrence of adverse obstetrical and neonatal outcomes in morbidly obese women with polycystic ovarian syndrome (PCOS)? Summary answer Patients with PCOS who underwent BS were at lower risk for gestational diabetes mellitus (GDM) and pregnancy-induced hypertension (PIH), than other women with PCOS. What is known already Studies have shown that PCOS in pregnancy is associated with the occurrence of GDM, preeclampsia, PIH, preterm birth (PTB), cesarean section, miscarriage, hypoglycemia, and neonatal death. Patients with PCOS may have an increased risk of obesity compared to the general population, which magnifies the inherent insulin resistance many fold. PCOS patients who underwent bariatric surgery have a marked improvement in menstrual irregularities, hirsutism, T2DM, hypertension, and dyslipidemia. The benefit of bariatric surgery for PCOS patients and the improvement of pregnancy related complications has not been adequately studied, with most studies being small. Study design, size, duration This is a retrospective study using the Health Care Cost and Utilization Project-Nationwide Inpatient Sample (HCUP-NIS) database from 2004 to 2014. Using multivariate logistic regression analysis, we compared women with PCOS who underwent BS with a control group consisting of pregnant patients with PCOS of all BMIs who had not had weight reduction operations regarding pregnancy, delivery, and neonatal outcomes. Participants/materials, setting, methods The study group included pregnant PCOS patients who underwent BS and the control group consisted of pregnant patients with PCOS; who delivered between 2004 and 2014. Demographic and clinical characteristics, pregnancy, delivery, and neonatal outcomes were compared. Multivariate logistic regression analysis was performed to control for all statistically different (P &lt; 0.05) confounding effects. Each subject was included once per delivery. Main results and the role of chance We identified 9,096,788 pregnancies during the study period. 141 patients had a history of PCOS and underwent BS. The control group was composed of 14,741 patients with PCOS who didn’t undergo BS. Prevalence of PCOS patients who underwent BS increased from 0/1,000 in 2004 to 14.6/1,000 in 2014(p = 0.001). Those who underwent BS were more likely to be older than 35-years(42.6% vs. 18.7%, p &lt; 0.0001), obese at delivery(44.7% vs. 22%, p &lt; 0.0001) and have a history of previous cesarean sections (24.8% vs. 18.2%, p = 0.045). Differences in pre-gestational diabetes (7.1% vs. 4.1%, p = 0.086) and hypertension (12% vs. 8.4%, p = 0.125) .The BS group was less likely to develop PIH (aOR–0.39, 95%CI–0.21–0.72) and GDM( aOR–0.40, 95%CI–0.23–0.70) when compared to the control group. When comparing the PCOS with and without BS; differences in gestational hypertension(95%CI–0.22–1.30), preeclampsia(95%CI–0.19–1.15), spontaneous vaginal delivery (95%CI 0.58–1.3), operative vaginal delivery (95%CI 0.34–1.8), Cesarean section (95%CI 0.79–1.79), post partum hemorrhage (95%CI–0.12–1.94), transfusion (95%CI–0.1–5.22), preterm delivery (95%CI–0.56–1.75) and maternal infection (95%CI–0.27–2.07) were similar. Regarding neonatal outcomes of PCOS with and without BS: small for gestational age babies (95%CI–0.26–2.68), and congenital anomalies (95%CI–0.09–4.52) were similar. Limitations, reasons for caution Limitations of our study include its retrospective design. Information regarding the time interval between the surgical intervention and pregnancy wasn’t available. Nor was information on the type of gastric bypass performed. Wider implications of the findings: Our study demonstrated an association between bariatric surgery in the setting of PCOS patients and a reduced risk of GDM and PIH. Although no differences were noted in other delivery and neonatal outcomes, data was not compared to a group of strictly obese PCOS controls. Trial registration number Not applicable

Background: The 2017 ACC/AHA Guideline categorized blood pressure into 4 levels:normal (SBP<120 and DBP <80mm Hg), elevated (SBP of 120–129 or DBP< 80 mmHg) and stage 1 (SBP of 130–139 or DBP of 80–89 mm Hg) or 2 (SBP≥140 orDBP≥90mmHg). Compared with the JNC7 guideline, the 2017 ACC/AHA guideline recommends using lower SBP and DBP levels to define hypertension.Objective: To determine the prevalence of hypertension as well as associated factors among students of the University of Kinshasa.Methods: This was a cross-sectional study conducted at the University of Kinshasa and including 1 281 students aged between 18 and 30. Blood pressure was assessed according to the WHO STEPwise approach, which is a standardized method of data collection, analysis and dissemination for the surveillance of non-communicable diseases in WHO member countries.The Chi-square and Student's t-tests and a multivariate logistic regression analysis have been used to evaluate the results. Statistical analyses were done using IBM SPSS version 21.Results: The prevalence of hypertension according to the guidelines from the 2017 ACC/AHA and the JNC 7 was 26.4 % (CI 95%; 23.9 - 28.9) and 7.3 % (CI 95%; 5.8 -8.8), respectively. The results of multivariate logistic regression analysis showed that smoking, alcohol abuse, overweight, male sex, age ≥ 24 years old and low physical activity were associated with hypertension (p < 0.0001).Conclusion: At least one out of four students had hypertension. These data should encourage public health authorities to develop strategies for screening of BP and topromote the adoption of healthy lifestyle in young adults.Keywords: Hypertension, risk factors, student, prevalence.

Several risk factors have been used to predict preeclampsia. The role of some risk factors as predictors associated with preeclampsia among Iranian women was analyzed in the present study using logistic regression. 610 women attending the obstetric ward of Mustafa hospital in Ilam were enrolled in this study. Demographic variables such as age, Body Mass Index (BMI), medical and obstetrics variables such as education, number of pregnancy, abortion and parity from May to September 2010 were analyzed. We used the unvaried and multiple logistic regression analyses to predict preeclampsia. The history of preeclampsia, hypertension, and infertility showed to be good independent predicator variables for preeclampsia using multivariate logistic regression analysis (OR was 5.46, 2.34 and 3.07 respectively). Area Under the Receiver Operation Character (AUROC) was estimated to be 0.67 (95% CI 0.59-0.67, p

Background and Purpose: Recurrent ischemic strokes increase the risk of disability and mortality. The role of conventional risk factors in recurrent strokes may change due to increased awareness of prevention strategies. The aim of this study was to explore the potential risk factors besides conventional ones which may help to affect the advances in future preventive concepts associated with one-year stroke recurrence (OSR). Methods: We analyzed 6,632 adult patients with ischemic stroke. Differences in clinical characteristics between patients with and without OSR were analyzed using multivariate logistic regression and classification and regression tree (CART) analyses. Results: Among the study population, 525 patients (7.9%) had OSR. Multivariate logistic regression analysis revealed that male sex (OR 1.243, 95% CI 1.025 – 1.506), age (OR 1.015, 95% CI 1.007 - 1.023), and a prior history of ischemic stroke (OR 1.331, 95% CI 1.096 – 1.615) were major factors associated with OSR. CART analysis further identified age and a prior history of ischemic stroke were important factors for OSR when classified the patients into three subgroups (with risks of OSR of 8.8%, 3.8%, and 12.5% for patients aged > 57.5 years, ≤ 57.5 years/with no prior history of ischemic stroke, and ≤ 57.5 years/with a prior history of ischemic stroke, respectively). Conclusions: Male sex, age, and a prior history of ischemic stroke could increase the risk of OSR by multivariate logistic regression analysis, and CART analysis further demonstrated that patients with a younger age (≤ 57.5 years) and a prior history of ischemic stroke had the highest risk of OSR.

Abstract Background Postanesthetic shivering is an unpleasant adverse event in surgical patients. A nonsteroidal anti-inflammatory drug has been reported to be useful in preventing postanesthetic shivering in several previous studies. The aim of this study was to evaluate the efficacy of flurbiprofen axetil being a prodrug of a nonsteroidal anti-inflammatory drug for preventing postanesthetic shivering in patients undergoing gynecologic laparotomy surgeries. Method This study is a retrospective observational study. I collected data from patients undergoing gynecologic laparotomy surgeries performed between October 1, 2019, and September 30, 2020, at Kumamoto City Hospital. All the patients were managed with general anesthesia with or without epidural analgesia. The administration of intravenous 50 mg flurbiprofen axetil for postoperative pain control at the end of the surgery was left to the individual anesthesiologist. The patients were divided into two groups: those who had received intravenous flurbiprofen axetil (flurbiprofen group) and those who had not received intravenous flurbiprofen axetil (non-flurbiprofen group), and I compared the frequency of postanesthetic shivering between the two groups. Additionally, the factors presumably associated with postanesthetic shivering were collected from the medical charts. Intergroup differences were assessed with the χ2 test with Yates’ correlation for continuity category variables. The Student’s t test was used to test for differences in continuous variables. Furthermore, a multivariate logistic regression analysis was performed to elucidate the relationship between the administration of flurbiprofen axetil and the incidence of PAS. Results I retrospectively examined the cases of 141 patients aged 49 ± 13 (range 21-84) years old. The overall postanesthetic shivering rate was 21.3% (30 of the 141 patients). The frequency of postanesthetic shivering in the flurbiprofen group (n = 31) was 6.5%, which was significantly lower than that in the non-flurbiprofen group (n = 110), 25.5% (p value = 0.022). A multivariate logistic regression analysis showed that administration of flurbiprofen axetil was independently associated with a reduced incidence of postanesthetic shivering (odds ratio 0.12; 95% confidence interval, 0.02-0.66, p value = 0.015). Conclusions My result suggests that intraoperative 50 mg flurbiprofen axetil administration for postoperative pain control is useful to prevent postanesthetic shivering in patients undergoing gynecologic laparotomy surgeries.
