Background: Hypertension is a significant risk factor of cardiovascular diseases, posing a serious threat to global health. Calcium plays an important role in regulating body homeostasis. The association of calcium with hypertension remains uncertain in the general population.Methods and Results: Cross-sectional data from the 2007–2018 National Health and Nutrition Examination Survey (NHANES) were analyzed. Adjusted multivariable logistic regression analysis and restricted cubic spline were used to investigate the association of serum calcium with the prevalence of hypertension. A total of 26,778 participants were included. The increase in calcium levels showed a positive association with the prevalence of hypertension in all three models with ORs of 1.347 (1.249–1.454), 1.522 (1.401–1.654), and 1.438 (1.306–1.583). The further subgroup analysis demonstrated a robust trend across all categories by sex, age, race, BMI, and eGFR. The restricted cubic spline plot exhibited an S-curve relationship between calcium and hypertension.Conclusion: Our cross-sectional study demonstrated a positive association between higher serum calcium level and the prevalence of hypertension. Our findings highlighted serum calcium level in hypertensive patients.

Objective: To determine the frequency of hypocalcemia in neonates with unconjugated hyperbilirubinemia receivingphototherapy.Study design and setting: Cross sectional study conducted at neonatal intensive care unit, King Abdullah Teaching Hospital,Mansehra for one year from December 2017 to November 2018.Methodology: Total 213 full term stable neonates of either gender with jaundice were studied in this study. Out of which,143 with unconjugated hyperbilirubinemia were exposed to phototherapy while 70 neonates with exaggerated physiologicalhyperbilirubinemia taken as control were not exposed to phototherapy. Serum calcium level was determined through bloodtest before and after 24 hours of phototherapy. SPSS version 22 was used to analyze the data. Frequency and percentageswere used to describe categorical variables like gender and hypocalcemia. Hypocalcemia was stratified by age and genderto see effect modifiers. Post stratified chi-square test was applied in which p value = 0.05 was considered as significancevalue.Results: In study group, 143 neonates who received phototherapy had mean age of 7 days ± 2.62 SD. Total 65% neonateswere male and 35% neonates were female. Mean serum calcium level of neonates before and after provision of phototherapywas 9.28 mg/dl ± 0.23 and 8.54 mg/dl ± 0.68 respectively, which is statistically significant. The frequency of hypocalcemiawas 40% in neonates with unconjugated hyperbilirubinemia after 24 hours of phototherapy.Conclusion: Hypocalcemia is an important complication in neonates with unconjugated hyperbilirubinemia after continuousphototherapy. Hypocalcemia has clinical impact and adds to morbidity, and if left untreated, can lead to mortality.

Background: Hypertensive disorders of pregnancy, including preeclampsia complicates about 10% of pregnancies worldwide. Preeclampsia is one of the major cause of maternal and perinatal morbidity and mortality worldwide. According to the National Health Portal of India, the incidence of preeclampsia is reported to be about 8-10% among pregnant women. The present study was aimed to compare mean serum calcium levels in preeclamptic and normotensive pregnant women at third trimester of gestation and assess relationship between maternal serum calcium levels, severity of disease and overall maternal and perinatal outcome.Methods: This was a cross sectional study conducted on 200 females divided into two groups (i.e. Study and Control Group) from 1st November 2019 to 31st October 2020. Informed consent was obtained for subjecting. Detailed history and clinical examination were performed. Serum calcium level was measured in both groups by spectrophotometric method.Results: Mean serum calcium level in study group (preeclamptic) was 7.84+0.74mg/dl while in control group (normotensive) mean serum calcium level was 9.68+0.97mg/dl. Serum calcium level was significantly lower in preeclamptic women than normotensive pregnant women (p<0.001).Serum calcium showed significant negative correlation with systolic and diastolic blood pressure.Conclusions: This study concludes that hypocalcaemia may have a role in aetiology of preeclampsia and adverse maternal and perinatal outcome. Thus intake of calcium supplements may help in reduction of incidence of preeclampsia especially in a population of a developing country.

Purpose The aim of this study is to determine the prevalence of hypocalcaemia among first-trimester pregnant women and its contributing factors. Design/methodology/approach A cross-sectional study was carried out among first-trimester pregnant women who were recruited during their first antenatal visit. A total of 396 respondents of age 18-40 years completed the self-administered questionnaire (socio-demographic, socio-economic, obstetric information), validated semi-quantitative food frequency questionnaire for calcium (FFQ-calcium), anthropometric measurements (weight and height) and blood test for serum calcium during their first trimester. Findings The prevalence of hypocalcaemia based on serum calcium level of less than 2.11 mmol/L was 26.0 per cent (n = 103). The median serum calcium level was 2.2 mmol/L (IQR, 25th and 75th percentile – 2.1 and 2.3, respectively). Milk intake of less than two glasses per day during pregnancy showed a twofold increase in developing hypocalcaemia (OR, 2.231; 95 per cent CI, 1.399, 3.588). Other than that, underweight (aOR, 2.038; 95 per cent SK, 1.088, 3.820) and obese before pregnancy (aOR, 1.954; 95 per cent SK, 1.007, 3.790) are also predictors of hypocalcaemia. Originality/value The prevalence of hypocalcaemia among first-trimester pregnant women in this study was 26.0 per cent. Intake of two or more glasses of milk per day can help prevent hypocalcaemia at this stage of pregnancy.

Background: Obesity is caused by several factors while sedentary lifestyle and excessive energy intake are the most important ones. Obesity could be due to abnormal calcium metabolism, and a high calcium intake may prevent obesity. Studying serum calcium level, albumin, and triglyceride concentrations, we searched for probable correlation between serum calcium level and anthropometric data of the participants.Materials and Methods: This cross-sectional study was performed in 2011 in Shiraz Endocrine and Metabolism Research Center on 468 participants. Anthropometrics and serum levels of calcium, albumin, and triglyceride levels were measured, recorded, and analyzed by SPSS statistical software.Results: 329 participants were female (70.3%) and the remaining were male (29.7%) with mean age of 46.08 ±15.22 years old. Corrected plasma concentration of calcium based on albumin level had a significant relation with weight, BMI, and triglyceride levels.Conclusion: It is assumed that obesity induces the production of inflammatory cytokines which stimulates bone absorption by osteoclasts that might subsequently lead to a higher serum calcium level in obese people who have a high level of triglyceride at the same time.

Background: Neonatal Hyperbilirubinemia is one of the leading causes for admission in NICU in the first week of life. This condition if left untreated may lead to irreversible neurological damage hence increasing mortality and morbidity in newborns. Neonatal Hyperbilirubinemia is treated with phototherapy which employs blue wavelengths of light to change unconjugated bilirubin in the skin. The bilirubin is then converted to less toxic water-soluble photo-isomers that are excreted in the bile and urine. There are several toxic effects to the use of this treatment, one of them being hypocalcemia.Methods: This study has been done at Mahatma Gandhi Institute of Medical Sciences in 2016-2018 on 100 new-borns to prove the effect of phototherapy on serum calcium levels in neonates with hyperbilirubinemia. New-born who were admitted in NICU for Hyperbilirubinemia were screened according to inclusion and exclusion criteria, their sample for serum calcium and serum bilirubin levels were taken as pre and post phototherapy samples.Results: It was observed that the mean Serum calcium level before phototherapy in neonates was 9.31 mg/dl with standard deviation of 0.69 mg/dl. Whereas after phototherapy mean serum calcium level in neonates was 8.88 mg/dl with standard deviation of 0.73 mg/dl. There was statistically significant mean difference in serum calcium level at before and after phototherapy in neonates (p<0.0001).Conclusions: This study proves the hypothesis that phototherapy can cause hypocalcemia in neonates with hyperbilirubinemia.

Background: Chronic kidney disease (CKD) is a silent epidemic. The true prevalence of CKD with in a population are very difficult to estimate, since early to moderate CKD were usually asymptomatic. ESRD in the consequence of CKD is one of the most expensive diseases to treat.Only way is to prevent it and Hence this was conducted to estimate the prevalence of CKD and its associated risk factors among adults in selected slums of Chennai.Methods: This is a cross sectional study done from May 2013 to June 2014 in selected slums of Chennai. The study population includes adult males and females. Multi stage sampling method used. Sample size covered was 400. A semi structured questionnaire used as tool. Based on the serum creatinine eGFR calculated using modified MDRD study equation and CKD prevalence was identified. The data was entered in MS excel and analyzed using SPSS version 21.Results: Total of 400 participants involved. Females were predominant in the study. Among them, 67 (16.8%) were diagnosed as CKD patients and Stage 1, 4.0% had stage 2, 3.6% had stage 3, 1.3% had stage 4 and 0.5% had stage 5 at the time of diagnosis.Conclusions: This study revealed prevalence of CKD among slum population was 16.8%. This study showed that old age, uncontrolled hypertension, uneducated, Diabetes with poor control, overuse of analgesics, H/o smoking, obesity, alcoholism, passive smoking, family H/o CKD and proteinuria were significant risk factor for CKD among study subjects. Slum population with risk factors should be regularly screened for CKD.

Intestinal parasitic infections are common among children worldwide. This study was aimed at determining risk factors for infection with soil transmitted helminths, Cryptosporidium spp., and Giardia duodenalis, among children in preschools. The study was in two parts: a cross-sectional study in which data were collected from 403 children from 10 preschools and a longitudinal study in which 100 children from four preschools from the previous 10 were selected. Prevalence of Ascaris lumbricoides was 12.0%, while that of hookworm was 8.3%. Overall prevalence of Cryptosporidium and G. duodenalis was 28.0% and 29.0%, respectively. Low education level of parent/guardian was a significant risk factor for A. lumbricoides (OR = 2.35, 95% CI: 1.02–5.41; P=0.04), while roofing types other than corrugated iron sheets were found to be protective for G. duodenalis infection in both bivariate and multivariate analyses (multivariate: OR = 0.67, 95% CI: 0.45–0.99; P=0.04). Low socioeconomic level was found to be protective for Cryptosporidium spp. infection in multivariate analysis (OR = 0.59, 95% CI: 0.35–0.99; P=0.04). In the longitudinal study, none of the factors were associated with either infection. These findings may have implications for other preschools in other districts in Zambia.

Background and Objectives: Video laryngoscopy has been proven useful under difficult airway scenarios, but it is unclear whether anticipated improvement of visualization is related to specific difficult intubation prognostic factors. The present study evaluated the change in laryngoscopic view between conventional and C-MAC® laryngoscopy and the presence of multiple difficult intubation risk factors. Materials and Methods: Patients scheduled for elective surgery with >2 difficult intubation factors, (Mallampati, thyromental distance (TMD), interinscisor gap, buck teeth, upper lip bite test, cervical motility, body mass index (BMI)) were eligible. Patients underwent direct laryngoscopy (DL) followed by C-MAC™ laryngoscopy (VL) and intubation. Change of view between DL and VL, time for best view, intubation difficulty scale (IDS) and correlation between prognostic factors, laryngoscopic view improvement, and IDS were measured. Results: One-hundred and seventy-six patients completed the study. VL lead to fewer Cormarck–Lehane (C/L) III-IV, compared to DL (13.6% versus 54.6%, p < 0.001). The time to best view was also shorter (VL: 10.82 s, DL: 12.08 s, p = 0.19). Mallampati III-IV and TMD ≤ 6 cm were related to improvement of C/L between DL and VL. Logistic regression showed these two factors to be a significant risk factor of the glottis view change (p = 0.006, AUC-ROC = 0.57, 95% CI: 0.47–0.66). 175/176 patients were intubated with VL. 108/176 were graded as 0 < IDS ≤ 5 and 12/176 as IDS > 5. IDS was only correlated to the VL view (p < 0.0001). Conclusion: VL improved laryngoscopic view in patients with multiple factors of difficult intubation. Mallampati and TMD were related to the improved view. However, intubation difficulty was only related to the VL view and not to prognostic factors.

Background Thrombocytopenia is the most common hematological abnormality in the neonatal period. Hemorrhagic manifestations are found in 10% cases of thrombocytopenia. Neonatal thrombocytopenia commonly assumed due to sepsis, despite many risk factors that may caused thrombocytopenia.Objective To obtain incidence and risk factors of neonatal thrombocytopenia.Methods A cross sectional study was conducted in April 2009. Complete blood counts investigation was performed before age of 24 hours, medical conditions and risk factors of mothers and subjects were noted, as well as hemorrhagic manifestations. Subjects with thrombocytopenia were followed for 2 weeks. The risk factors consisted of hypertension in pregnancy, pre-eclampsia, eclampsia, intrauterine growth retardation, gestational diabetes mellitus, perinatal infection, asphyxia, sepsis, and necrotizing enterocolitis.Results Neonatal thrombocytopenia was found 17 (12.1%) of 140 subjects, consisted of 88.2% early onset and 11.8% late onset. Significant risk factor of mother was pre-eclampsia (PR 3.97, 95%CI 1.70 to 9.25), while significant risk factors of neonates were asphyxia (PR 5.66, 95%CI 2.49 to 12.86), sepsis (PR 5.33, 95%CI 2.33-12.19) and necrotizing enterocolitis (p=0.014; PR 9.2 95% CI 5.17 to14.84). We found 29.4% hemorrhagic cases of neonatal thrombocytopenia (i.e.,. skin, gastrointestinal, intracranial hemorrhage).Conclusions The incidence of neonatal thrombocytopenia was 12.2%. Significant risk factor of mother that caused thrombocytopenia was pre-eclampsia, while risk factors of neonates were asphyxia, sepsis and necrotizing enterocolitis.[Paediatr Indones. 2010;50:31-7].
