Systemic arterial hypertension (SAH) is considered an important risk factor for the development of cardiovascular diseases. The aim of the present study was to verify the effects of a short cardiovascular rehabilitation program (CR) in hypertensive subjects. The clinical pilot study involved a sample composed of 11 hypertensive subjects. It was evaluated the weight, height, body mass index (BMI), waist and hip circumference, waist hip ratio, systolic blood pressure (SBP), diastolic blood pressure (DBP) and six-minute walk test (6-MWT) before and after CR. CR was performed twice a week for 60 minutes. The results shown that after CR occurred a reduction of waist circumference (99.86±8.7 to 95.2±8.6 cm, p=0.0002) and hip circumference (110.18±14.75 to 105.00±12.7 cm p=0.01) values. About the mean distance walked in the 6-MWT there was an increase after the CR program (335.9±123.5 m to 554.56±87.9 m, p=0.000). In conclusion, the results suggest that a short CR is an effective for the treatment of hypertensive subjects. After 16 CR sessions, functional and musculoskeletal capacity was improved, evaluated by 6-MWT. Furthermore, the short CR program decreased waist and hip circumferences, being an important option for these subjects. Although. There were no changes in baseline blood pressure levels.
Hand-to-hand bioelectrical impedance (HH BIA) is a low-cost method to estimate percent body fat (%BF). The BIA method is consistently reliable, but questions on validity remain. We have observed anecdotally that elbow position can render consistently different measures of %BF while using HH BIA, thus leading to the question: Does elbow angle influence the validity of measures derived using HH BIA? The purpose of this study was to assess the effect of elbow position (i.e., IN=flexed to 90° versus OUT=fully extended) on the reliability of HH BIA on 44 male and 24 female healthy adults (age=21±2 yrs, BMI=23±3). An additional aim was to assess the validity of the HH BIA %BF on a subset of subjects (n=12) using air displacement plethysmography (BOD POD®) as the criterion measure. The IN position was ~4%BF lower than the OUT position for HH BIA (p=0.05, effect size=0.67). Measures of %BF for both trials for the IN [intraclass correlation coefficient (ICC)=0.99, coefficient of variation (CV)=2.99%] and OUT (ICC=0.99, CV=1.48%) conditions were highly reliable. On the subsample, the OUT (18.3±6.7 %BF) position exceeded both the IN (14.5±7.4 %BF) and the BOD POD® (16.1±7.8 %BF) measures (p<0.05); however, IN and BOD POD® measures of %BF did not differ (p=0.21). These findings support that HH BIA is a reliable measure at both elbow positions; however, %BF estimations vary considerably (~4%) with respect to the criterion measure depending on elbow position. The OUT position was found to overestimate criteria %BF. Further research may reveal an optimum elbow angle position for HH BIA estimates of %BF.
Anthropometric characteristics, represent one of the most important subsystems within the “system” of man, and which can be in affected by physical exercises in the direction of the desired transformation. Very often the anthropometric parameters (height and weight) are used in the assessment of the morphological status of an individual, and on the basis of the results of Body Mass Index (BMI) bring certain estimates and conclusions. BMI as a statistical measures, is used in many public health campaigns as an approximate measure of the ideal body mass and the degree of nutrition of a population. The main goal of the research was to determine and analyze differences in BMI parameters between male and female students, aged 18±0.5 years, and determine the trend of changes. Using the T-test module, the obtained results confirmed that there are statistically significant differences in body height (t=8,17; p<0.001) and body weight (t=5,29; p<0.001), while in BMI values there are not statistically significant differences (t=-0.68, p>0.001). Based on BMI values, a positive trend of somatic changes of both poles is evident.
Background: An increasing body of evidence indicates that inflammatory activation profoundly impacts the electrophysiological properties of cardiomyocytes. A marker of systemic inflammation such as C-reactive protein(CRP), is associated with all parameters of the Mtabolic syndrome(MetS) and that may result in adverse cardiac events via multiple effects, ultimately resulting in a prolongation of Action Potential duration (APD), and thereby of the QTC (QT corrected) interval on ECG.
Objective: We sought to investigate the influence of CRP levels on the prevalence of prolonged QT-dispersion and prolonged Tpeak-Tend –dispersion in the patients with MetS.
Methods: We conducted a multicenter observational cross-sectional study. The study population consisted of 200 patients with MetS, stratified in two groups:103 participants (50 females and 53 males) with level of CRP>3mg/l, and 97 participants (47 females and 50 males) with level of CRP<3mg/l), who attended outpatient visits at general cardiology Health Care Clinics during 1 calendar year. For the analysis of the ECG, we performed a manual measurement of the values using a digital caliper with measuring range of 0-150 mm, 0.01 mm resolution, and 0-100 ± 0.02 mm accuracy. QT interval dispersion was obtained by the difference between the maximum and the minimum QT intervals found in the 12-lead electrocardiogram. The Tpeak-Tend interval was obtained from the difference between QT interval and QTpeak interval.
Results: Prolonged QTC. dispersion, was found in 51.4% of participants with level of CRP>3mg/l and in 32.9% of with level of CRP<3mg/l, the differences were statistically significant. (p=0.004). The results showed that 51.4% participants with level of CRP>3mg/l had a prolonged Tpeak-Tend interval, and 32.9% of participants with level of CRP<3mg/l had prolonged Tpeak-Tend interval. Difference were statistically significant.( p=0.04). There were significant association of increased levels of CRP and QTC-dispersion (OR = 2.486, 95% CI 1.389-4.446).There were significant association of increased levels of CRP with Tpeak-Tend Dispersion (OR=2.239,95%CI 1.262-3.976). Prolonged QTC max. Interval OR=2.236,%CI 1.246-4.014),Prolonged Tp-Te-interval. (OR=2.367, 95%CI 1.327-4.222), also there were significant association of increased levels of CRP with BMI. (OR=1.154, 95%CI 1.095-1.227) and significant association of increased levels of CRP with presence of uncontrolled glicemia.(OR=1.779, 95%CI 1.014-3.12).
Conclusion: We think we proved the hypothesis that patients with MetS and high level of CRP have higher prevalence of QT- dispersion and Tpeak-Tend dispersion than patients with MetS and lower level of CRP. These findings have both epidemiological and clinical relevance, also these findings might lend further insight into potential mechanisms by which MetS is associated with adverse cardiac events.
Background: There is an important shortage of blood in the greatest blood banks worldwide to meet up with requirements for numerous medical interventions. Limited studies have associated regular blood donation to the lowering of lipid function parameters. Assessing the lipid function is a classical method of evaluating an individual’s risk for coronary heart disease.
Objective: The general goal of the study is to determine lipid and hematological profile among blood donors in European Gaza Hospital, Palestine.
Materials and Methods: This study was a case-control study that involved 120 male, 40 of whom were regular blood donors (study group), 40 first time donors and 40 non- donors (control group) aged between 18-60 years. A volume of 5ml venous blood was drawn from each fasting participant into a dry biochemistry screw-capped tube. This was allowed to clot and the serum was used to determine total cholesterol (TC), triglycerides, High-density lipoprotein cholesterol (HDL-C), Low-density lipoprotein cholesterol (HDL-C), while HDL-C/LDL-C and TC/LDL ratio were calculated by using the following formula. Anthropometric parameters (weight, height) of donors were measured using standard protocol. The height (in meter), weight (in kilogram) were used to calculate the body mass index (BMI) using the following formula. BMI= weight (kg)/ (height in meter)² and blood was collected from each participant in EDTA (for hematocrit, ESR). Three groups were matched for age and BMI. Data were analyzed using SPSS version 23. Chi-square (χ²) was used to compare the relationship between categorical variables, ANOVA was used to measure the difference between means. Data were summarized using tables, pie charts, histograms. A P-value < 0.05 was considered to be statistically significant for all tests conducted.
Results: The mean total cholesterol (169±10.85 mg/dl), triglycerides (116±9.73 mg/dl), HDL (54±2.5 mg/dl ), LDL (92±11.4mg/dl), LDL/HDL ratio (1.73±0.25) and TC/HDL ratio (3.16±0.26) were lower in the regular blood donors than the first time donors(198±10.13, 179±5.82, 42.33±1.6, 120±11.2, 2.85±0.36, 4.7±0.40) and non- donors (202±10.19, 180±12.68, 41.75±1.4, 125±11.7, 2.99±0.33, 4.86±0.32) respectively and statistically significant (P < 0.05).The mean ESR (6.63±0.87mm/hr) was lower statistically significant in the regular blood donors than the first time donors (7.40±1.17) and non- donors (7.60±1.48) respectively (P < 0.05). The mean HCT (42.98±0.86%) was lower statistically significant in the regular blood donors than the first time donors (44.63±0.90) and non- donors (44.75±0.74, P < 0.05).
Conclusion: Regular donors have reduced risk of developing coronary heart disease as reflected by the low total cholesterol, triglycerides, LDL-c, LDL-c/HDL-c ratio, TC/HDL-c ratio and HCT and high HDL. BMI in regular donor was less than the donor for the first time and did not donate, but did not reach the statistical significance. Also in our study regular donors have reduced risk of developing inflammation as reflected by low ESR.
Purpose: There are uncertainties about whether general or central obesity is the more important determinant for blood pressure and hypertension in young Chinese. We aim to investigate the association between adiposity measures and blood pressure and hypertension in young medical students.
Methods: A total of 380 medical students were recruited from the 2012 batch in the Clinical College of Dali University. Anthropometric measures and office blood pressure were measured. Blood pressure status was defined by Chinese hypertension guidelines and ACC/AHA 2017 hypertension guidelines, respectively. We examined the associations of adiposity measures (body weight, body mass index [BMI], waist circumference, hip circumference, waist-to-hip ratio [WHR], waist-to-height ratio [WHtR], ponderal index [PI], body adiposity index (BAI) and conicity index [CI]) with blood pressure and hypertension by sex.
Results: In 380 subjects (women 66.6%, mean age 21.5 years), the prevalence of obesity (BMI ≥ 28 kg/m2) was 2.1%, and the prevalence of hypertension was 2.6% (≥ 140/90 mmHg) and 24.5% (≥ 130/80 mmHg), respectively. In correlation analyses and multivariable-adjusted linear regression analyses, most adiposity measures of central obesity were significantly associated with blood pressure in men, while in women, either adiposity measures of central or general obesity were associated with blood pressure. The predictive power of adiposity measures for hypertension was generally low in men. However, adiposity measures of either general obesity or central obesity were predictive for hypertension defined by Chinese hypertension guidelines in women.
Conclusion: There are gender-specific associations of central and general obesity with blood pressure and hypertension in young Chinese medical students.
Background: Previous studies highlighted the negative effect of premature progesterone elevation (PE) during IVF cycles on the cycle outcomes. The aim of this study was to assess the validity of progesterone level on hCG day (P4) in the prediction of IVF/ICSI cycles’ outcome.
Methods: In a retrospective cohort study, all fresh cycles of 256 patients who underwent IVF or ICSI cycles in 2017 at reproductive endocrinology & infertility unit/ Obg/Gyn department at King Abdulaziz Medical city, Riyadh, Saudi Arabia, were followed up. They were started on gonadotropin medications for ovarian hyperstimulation, followed by serial transvaginal U/S and serum estrogen levels each visit. Patients having 2 or more 18mm follicles were triggered by hCG 10,000 IU and ovum pickup was done 34-36 hrs after. Data were collected on patients’ characteristics [age, BMI infertility type], cycles’ characteristics [number of follicles and endometrium thickness on hCG day, P4 and estrogen levels], rates of pregnancy and pregnancy outcomes. Receiver operating characteristic curve was applied to determine the cut-off of P4 that corresponds with a negative pregnancy test. Logistic regression analysis was used and significance was considered at p - value of ≤0.05.
Results: Pregnancy rate in the study sample was 36.7%. The mean P4 level in cycles with negative pregnancy tests was significantly higher than the mean in cycles with positive tests (p = 0.018). After adjusting for confounders, significant negative association between P4 and pregnancy rate was evident (p < 0.03). The optimum trade-off of P4 for prediction of a negative pregnancy test was 1.5nmol/L. This cut-off level had a 59% sensitivity, 51% specificity and 68% positive predictive value and 10% & 15% absolute and relative risk reductions respectively. Cycles with mean P4 of ≥1.5nmol/L were significantly associated with primary infertility (p = 0.011), lower mean BMI (p = 0.009) higher mean estrogen level (p < 0.001), lower live birth rate (p = 0.048), higher abortion rate (p = 0.039), and higher ovarian hyperstimulation rate (p = 0.027).
Conclusion: Premature elevation of progesterone level on the hCG day in IVF/ICSI cycles may have adversely impacted the pregnancy rate and pregnancy outcome. The cutoff point of 1.5nmol/L for this P4 was not valid in predicting pregnancy outcomes.
Study design: A consecutive case series study
Purpose: To investigate whether Low Back Pain (LBP) in women with primary singleton pregnancy induces disability.
Background: LBP is reported to be increased in pregnants than in non-pregnant women. Different outcome measures have been used to search for correlations between pain and disability.
Methods: 167 pregnant women aged 30 ± 3.5 years participated. Two equal categorial age groups were constructed: Group A included women aged 23 - 29 years, and Group B women aged 30-39 years. Their weight was 76 ± 13 kg prepartum and the Body Mass index (BMI) was 28 ± 4 prepartum. Visual Analogue Scale (VAS) was used for LBP pain intensity and Oswestry Disability Scale (ODI) for disability estimation in the last three months prepartum and in the first three months postpartum.
Results: The women weight was 67 ± 13 kg postpartum. The BMI was 24 ± 4 postpartum. There was no difference in VAS and ODI scores versus BMI, weight and height between the two age groups in both periods of observation: prepartum and postpartum. Prepartum, 81.4% of women claimed LBP that dropped to 55.5% postpartum. ODI score dropped from 19.5 ± 13.6% prepartum to 11 ± 12% postpartum. The ODI subscales that showed significant reduction postpartum were: Pain intensity (P = 0.002); working (P = 0.009); sitting (P = 0.004); standing (P = 0.003); sleeping (P = 0.008); and traveling (P = 0.006). VAS prepartum was increasing as the weight was increasing in both periods of observation (P = 0.015 and P=0.051) respectively. VAS prepartum was significantly correlated with BMI prepartum (P = 0.019) and postpartum (P = 0.028).
Discussion: Physical disability in pregnant women was low and reduced following delivery. Disability was linked with LBP intensity, weight, BMI and height, but not with age or educational level.
Despite the background of advances in cardiac surgery procedures for higher risk population, the postoperative complication has already been a challenge for cardiac surgeon and Heart-Team. Future perspectives to exceed this challenge could be periodically patient’s follow up and advance diagnostic workup. We describe the diagnosis of a large sub mitral left Ventricle Pseudoaneurysm that was identified in a 59-year-old woman 17 years after she underwent aortic and mitral valve replacement for rheumatic valvular disease
Objective: The primary aim of this study was to measure pressure generated on a Tuohy needle during the epidural procedure in labouring women of varying body mass indices (BMI) with a view of utilising the data for the future development of a high fidelity epidural simulator. High-fidelity epidural simulators have a role in improving training and safety but current simulators lack a realistic experience and can be improved.
Methods: This study was approved by the National Research Ethics Service Committee South Central, Portsmouth (REC reference 11/SC/0196). After informed consent epidural needle insertion pressure was measured using a Portex 16-gauge Tuohy needle, loss-of-resistance syringe, a three-way tap, pressure transducer and a custom-designed wireless transmitter. This was performed in four groups of labouring women, stratified according to BMI kg/m2: 18-24.9; 25-34.9; 35-44.9 and >=45. One-way ANOVA was used to compare difference in needle insertion pressure between the BMI groups. A paired t-test was performed between BMI group 18-24.9 and the three other BMI groups. Ultrasound images of the lumbar spine were undertaken prior to the epidural procedure and lumbar magnetic resonance imaging (MRI) was performed within 72h post-delivery. These images will be used in the development of a high fidelity epidural simulator.
Results: The mean epidural needle insertion pressure of labouring women with BMI 18-24.9 was 461mmHg; BMI 25-34.9 was 430mmHg; BMI 35-44.9 was 415mmHg and BMI >=45 was 376mmHg, (p=0.52).
Conclusion: Although statistically insignificant, the study did show a decreasing trend of epidural insertion pressure with increasing body mass indices.
Context: Perioperative management of morbidly obese patients undergoing bariatric surgery is challenging. Lacking standardized perioperative protocols, complication rates may be high. This retrospective study aims to quantify the incidence of significant blood pressure decreases on induction of anesthesia and intraoperative hypoxemia, before implementation of a standardized protocol designed for bariatric surgery.
Design: Retrospective, observational study.
Setting: A 250-bed county hospital in northern Sweden.
Subjects: 219 morbidly obese patients (body mass index > 35 kg/m2) who underwent bariatric surgery between 2003 and 2008.
Main outcome measures: Incidence of systolic blood pressure (SAP) falls to less than 70% of the preoperative baseline during induction of anesthesia and incidence of perioperative hypoxemia.
Results: The incidence of confirmed SAP falls to below 70% of baseline at induction of anesthesia was 56.2% (n = 123/219). This incidence rose with increasing age (p < 0.001) but not with body mass index (BMI). 3.7% (n = 8/219) of cases were marked as difficult intubations. A transient period of hypoxemia was observed in 6.8% (n = 15/219) and was more common with increasing BMI (p = 0.005). Fourteen different drug combinations were used in the study population. Of those administered an induction anesthetic drug, 72.6% (n = 159/193) were given an overdose when calculated by lean body weight, but this did not correlate significantly to SAP falls (p = 0.468).
Conclusion: The incidence of a significant blood pressure fall upon induction of anesthesia was common. The incidence of airway and ventilation problems were low. Overdosing of anesthetics and excessive variation in applied anesthesia methods were found.
This study aimed to investigate the relationship between muscle weakness and cancer-related symptoms in patients undergoing chemotherapy for hematological malignancies and solid tumors. We recruited hospitalized patients older than 20 years who were receiving chemotherapy. Patients were divided into a solid tumor (n=74) and hematological malignancy (n=80) group. Age, body mass index (BMI), strength and thickness of the quadriceps femoris muscle, serum albumin and C-reactive protein levels, blood hemoglobin concentration, fatigue, psychological distress and pain, and duration of hospitalization were assessed. Eight physical symptoms (fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, and diarrhea) were also evaluated. Correlation and multiple regression analyses were conducted to identify factors affecting muscle strength in each group. Muscle strength was associated with fatigue in the solid tumor group and with age, BMI, muscle thickness, albumin and hemoglobin in the hematological malignancy group. Therefore, factors contributing to muscle strength might differ between patients with solid tumors and those with hematological malignancies. In particular, fatigue was an important factor in patients with solid tumors, while anemia was an important factor in patients with hematological malignancies. We therefore suggest that different treatments for muscle weakness might be considered for patients with these cancer types.
The success of vaginal birth after cesarean section (VBAC) has been correlated with a variety of maternal characteristics such as age, ethnicity, and body mass index (BMI, calculated as weight in kilograms divided by height in meters squared). The patient’s BMI just prior to delivery has been shown to be a better prognostic indicator of success than pre-pregnancy BMI. Gestational weight gain was previously associated with a decreased rate of successful VBAC. More recent research has not supported such an association. The objective of our study was to further validate these findings with a larger population.
We performed a retrospective cohort study of women undergoing trial of labor after cesarean (TOLAC) at our institution from January 2010 to December 2019. Women were divided into three groups based on weight gain in pregnancy as compared to the American College of Obstetrics and Gynecology (ACOG) recommendations (i.e. < 25 pounds (lbs), 25-35 lbs, > 35 lbs). We further subdivided the pregnancies between term and preterm deliveries. The primary outcome was a successful VBAC. Of 1087 patients attempting a TOLAC, 772 (71%) were successful and 315 (29%) failed VBAC. When grouped according to ACOG weight gain recommendations, 303 (31%) women were below ACOG guidelines, 318 (33%) met guidelines, and 339 (35%) exceeded guidelines. There was no difference in the rate of VBAC success among the three groups. When counseling patients, providers should still promote healthy dietary habits but should not correlate excess weight gain with chance of TOLAC success.
Ischemic heart disease may occur in isolation, or in combination with the pathological process of vascular ageing, arteriosclerosis. These two conditions have differing impacts on the haemodynamic changes in response to anaesthesia and surgery. Hypertension is not a feature of ischemic heart disease, and vice versa, but where the two conditions co-exist, hypertension aggravates and accelerates the pathological processes of ischemic heart disease. Patients older than 40 yrs. presenting for anaesthesia and surgery must therefore be considered at risk of any combination of these three conditions. Anaesthetic techniques must also be chosen to minimize haemodynamic changes which in the normal healthy patient cause no serious morbidity, but which, in the patient with ischemic heart disease, can lead to serious morbidity or death. Here we report a 70 years old (BMI of 23.3) elderly, hypertensive Male patient with ischemic heart disease with previous MI (EF of 40% - 5%) undergoing elective Inguinal hernia repair. We Opted Spinal anesthesia over General anaesthesia as it should be an asset in cardiac patients undergoing non-cardiac lower abdominal surgeries to reduce preload and after load, stress response, coagulation responses, improves coronary perfusion, provides better postoperative analgesia, reduces incidence of perioperative MI, maintains myocardial oxygen supply demand ratio and avoids harmful effects of GA such as hypotention due to intravenous induction drugs, tachycardia and hypertension due to pressor response during direct laryngoscopy and tracheal intubation.
Introduction: Chronic low back pain is one of the most prevalent musculoskeletal disorders. Studies have shown certain relations between physical fitness and chronic low back pain (CLBP) by examine some measures of physical fitness. The aim of study was to measure lung function using winspiro PRO in patient with CLBP versus normal healthy individual, and relation of lung function with duration and intensity of CLBP.
Methodology: The study population is comprised of a total of 120 adult persons. 60 subjects with chronic low back pain (41 male and 19 female) with a mean age of 30.69 years (+4.34) and 60 normal individual (39 male and 21 female) with mean age of 29.00 years (+5.34).
Results:The result of comparison of the respiratory parameter forced vital capacity (FVC), and maximal voluntary ventilation (MVV) of individual with CLBP show a significant difference as compare to the normal healthy population. In unrelated ‘t’ test the patient with CLBP (N=60) of age 30.51(SD±4.33), height 169cm (SD±1.23), weight 57.86(SD±7.73) and body mass index (BMI) 20.46 (SD±2.54) show a significant difference in respiratory parameter FVC ( t=17.244, P=0.000), and MVV ( t=11.048, P=0.000) as compare to the normal healthy persons (N=60) of age 29.79 (SD±5.28), height 170cm (SD±1.13), weight 59.40(SD±6.97) and BMI 21.59 (SD±3.29).In patient group- FVC range is 34.0% to 75.00% (52.85%±9.30). MVV range is 45.0% to 86.80%. (63.11%±12.06)In control group FVC range is 63.90% to 98.83% (83.63%±7.59). MVV range is 63.00% to 98.00% (78.96%±7.86).
Conclusions:The overall result of the study show that there is a significant difference in the respiratory parameter that is FVC (forced vital capacity), and the MVV (maximum voluntary ventilation) in persons with chronic low back pain as compare to the healthy person of same age, height, weight and body mass index (BMI).
Objectives: Our main objectives are to reveal the pregnancy and neonatal impacts of COVID-19 infection and to compare it to the results that are reported in the literature.
Methods and materials: The characteristics of the admitted pregnant patients COVID-19 positive with their initial presentation, course at the hospital, and short term follow-up are exposed. Correlation of the age and gestational age with the severity of the disease was calculated.
Results: Thirty five COVID-19 positive pregnant patients presented between the beginning of March and the end of April 2020. From 5 weeks till 41 weeks of gestation, all trimesters were included. The mean of age is 32 and the BMI equal 28.2. Associated comorbidities included not only diabetes and hypertension but also PCOS. The symptomatology was considered mild in most of the cases. The distribution of the symptoms included cough in 86%. 10 out of 35 delivered and cesarean was performed in 50% of the cases. The mean length of stay is 6 days. Neither maternal nor neonatal deaths occurred. There is a significant correlation between the age of the patient and the severity of the disease but this is not the case with gestational age.
Conclusion: Our results were comparable to the literature in terms of initial presentation, associated comorbidities and the length of stay. Despite the fact that the cesarean rate was high, it was far below that of the literature. More data is still needed about COVID-19 in pregnancy.
Aim of this work is to analyze the coronavirus viral surface properties related the pattern of electrical features.
This chemical physical property is relevant and crucial to set profile of diffusion, severity of disease, efficacy of therapeutic strategy and in order to search new way to fight COVID-19 and the NEW VARIANT.
The phenomena of immune evasion and the different pattern of efficacy towards variants of some vaccine or some antibodies combination produce the need to verify if considering the electrical feature of viral surface can be a right tool or not.
As result of this research it is possible to submit to the scientist that the viral surface properties and electrical feature can be an element to be considered in various preventive or treatment measure.
The specificity of action of some vaccine or antibodies seem to tell us that also the aspecific methods are useful.
A specific chemico physical factors can influence the electrical charges viral surface behavior.
Hpertonic saline solution, humidity, electrical charge barrier in mask are simply example of the effect.
That can be obtained action on viral surface chemico -physical properties.
Objective: to determine the incidence of HBV and HCV in pediatric ward.
Sitting: 2ed March teaching hospital, sebha Libya.
Materials and Methods: this was a prospective hospital base study of pediatric cases admitted to 2ed March teaching hospital during a period from March 2018 to February 2019. Pediatric cases were studied for the incidence of HBsAg and HCV Ab by ELISA, Rapid technique. The positive result was confirmed with line immuno-assay.
Results: the study showed positive HBsAg in 12 patients and HCV in 2 cases out 25 cases represented with acute hepatitis from a total of 1763 pediatric cases were submitted in this study, with incidence rate of 0.68% and 0.11% respectively.
Conclusion: the incidence of HBV and HCV are low in Sebha, therefore active program need to be applied to control the spread of infection among the population.
Introduction: Ankle sprain is a widespread impairment in sport groups; this impairment leads to an absence from the workplace. The ankle sprains incidence rates are induced by height, weight, BMI, physical fitness, level of match, classification of sport, and personal exposure to sport.
Methods: A longitudinal case-control study was executed to verify the outcome of risk factors for ankle sprain at a Military Male School between 2012 and 2013 of 4987 people at risk for ankle sprain, a total of 234 cadets sustained new ankle sprains during the study, 432 non-injured cadets randomly selected as the control group.
Results: Regarding to the total people at risk in our study the incidence rate was approximately 5/1000 ankle sprain-years. Cadets with ankle sprains had higher weight, BMI and higher scores in Army Physical Fitness test than the control group. Ankle sprain occurred most commonly during athletics (51.4%). Ankle sprain incidence rate did not significantly vary from different athletic competitions after controlling for athlete-exposure. Soccer and Ball Games had the highest ankle sprain incidence rate.
Conclusion: Higher weight, increased BMI, greater physical conditioning and athlete exposure to selected sports were all risk factors for ankle sprain.
Objective: This study aimed to investigating of the epidemiological aspects of infertility and related risk factors in infertile women.
Materials and methods: This cross-sectional study, carried out on 330 infertile women referred to two infertility treatment center of Imam Khomeini Hospital and Mother center in Sari, Iran, from April 2015 to March 2017.
Results: 54.5% of these women were in the age of 30-39 years, infertility duration in 55.2% was 1-5 years, Body mass index (BMI) in 44.5% of samples was 26-30 kg/m2, 54.5% had diploma and associate degree. 63.6% lived in urban areas. 74.5 % of patients reported primary infertility. History of polycystic ovarian syndrome (PCOs) and pelvic inflammatory disease (PID) and poor ovarian reserve were the most common causes and risk factors for the infertility with prevalence 19.42%, 16.81% and 13.91%, respectively.
