Abstract
Background Oxygenation index [OI = (MAP × FiO2 × 100)/PaO2] assesses the severity of hypoxic respiratory failure. Oxygen saturation index [OSI = (MAP × FiO2 × 100)/SpO2] is a noninvasive method to assesses the severity of hypoxic respiratory failure. Conventionally used PaO2/FiO2 (P/F) ratio to measure the severity of ARDS requires arterial blood gas (ABG) sampling. It tenders limited prognostic information mandating the need for better markers. Oxygenation index (needs arterial sampling) and OSI (a noninvasive method) are substitutes to provide mortality information in ARDS patients. We evaluated the correlation between P/F, OI, and OSI in invasively ventilated COVID-19 ARDS patients (C-ARDS) and looked at its relationship with mortality. Patients and methods A retrospective study of invasively ventilated C-ARDS >18 years of age managed in COVID ICU. Ventilator settings (FiO2, mean airway pressure), pulse oximetry (SpO2), and ABG values (PaO2) were simultaneously noted at the time of sample collection. Patient outcomes (alive and deceased) were documented. Differences in parameters between survivors and nonsurvivors were assessed using independent sample t-test. Receiver operating characteristic (ROC) analysis with Youden's index was used to identify cutoff values to determine survival. Results A total of 1557 measurements for 203 patients were collected over the maximum duration of 21 days after ventilation. About 147 (72.4%) were males and 56 (27.6%) were females. On day one of ventilation, 161 (79.3%) had P/F ratio <200, 28 (13.8%) had P/F ratio between 200 and 300, and 14 (6.9%) had P/F ratio >300. There was a linear relationship between P/F ratio and OSI (r = -0.671), P/F and OI (r = -0.753), and OSI and OI (r = 0.893) (p < 0.001). After natural log transform, the correlation between these factors became stronger [P/F ratio and OSI (r = -0.797), PF and OI (r = -0.949), and OSI and OI (r = 0.902) (p < 0.001)]. About 74 (36.5%) patients survived. Survivors had significantly higher P/F ratio as compared with nonsurvivors (p < 0.05). Oxygen saturation index and OI were significantly lower in survivors as compared with nonsurvivors. Based on day-1 reading, a higher OSI (AUC = 0.719, 95% CI = 0.648-0.790) and OI (AUC = 0.752. 95% CI = 0.684-0.819) significantly can predict mortality. On the other hand, a higher P/F ratio can predict survival (AUC = 0.734, 95% CI = 0.664-0.805). P/F ratio of 160 on day 1 can predict survival. Oxygen saturation index values above 10.4% and OI above 13.5% were the cutoff derived for day 1 values to predict mortality. Conclusion Noninvasive OSI can be used to assess the severity of hypoxic respiratory failure in C-ARDS without arterial access in resource-limited settings. Oxygen saturation index can noninvasively provide prognostic information in invasively ventilated C-ARDS patients. How to cite this article Vadi S, Suthar D, Sanwalka N.

Abstract
Background and Objectives : Alveolar rupture following increased transalveolar pressure on positive pressure ventilation is associated with pulmonary barotrauma (PB). The spectrum varies from pneumothorax, pneumomediastinum, pneumopericardium, pneumoperitoneum, retro-pneumoperitoneum and subcutaneous emphysema. We studied the incidence of PB and their clinical characteristics in patients with coronavirus disease 19 (COVID-19)-associated acute respiratory failure. Methods Patients aged >18 years with COVID-19-associated acute respiratory distress syndrome were included in the study. We recorded demographics (age, gender, comorbidities), severity scores (APACHE II on admission, SOFA on the day of barotrauma), type of PB and outcomes at discharge from the hospital. Patient characteristics are descriptively reported. Survival analysis was done using Kaplan-Meier survival tests after classifying by various factors. Survival was compared using the log-rank test. Results Thirty-five patients experienced PB. Eighty per cent of patients in this cohort were males with mean age of 55.89 years. The commonest comorbidities were diabetes mellitus and hypertension. Twelve spontaneously breathing patients developed barotrauma. Eight patients experienced sequential events. In all, 18 patients required insertion of pigtail catheters. The median survival time in patients was 37 days (95% CI: 25-49 days). The overall survival rate was 34.3%. Mean serum ferritin levels were six times upper limit of normal in deceased, reflecting the severity of lung involvement. Conclusion A high incidence of PB was noted following severe acute respiratory syndrome coronavirus (SARS CoV-2) infection even in the non-ventilated patients, a consequence of SARS CoV-2 effects on the pulmonary parenchyma causing widespread lung injury.

Abstract
BACKGROUND The objectives of this study were to 1) evaluate the dietary diversity scores (DDS) and food variety scores (FVS) among Indian children and adolescents aged 9-18 y; 2) compare the DDS and FVS in association with demographic, socioeconomic, and health characteristics (growth and hemoglobin [Hb] concentrations); and 3) determine DDS and FVS cutoffs to identify dietary micronutrient adequacy. METHODS This study was performed in a subset (n = 1845) of children and adolescents enrolled in a multicenter study (2016-2017) from urban and rural areas of six Indian states. Height, weight, and Hb were measured, and anthropometric Z-scores were computed. Sociodemographic data were collected using a structured questionnaire. Dietary data collected by 24-h dietary recall were used to calculate the DDS and FVS. The mean adequacy ratio (MAR) for 10 micronutrients was computed. Receiver operating characteristic analysis was performed to define cutoffs of DDS and FVS. RESULTS In comparison with children and adolescents from rural areas, urban children and adolescents consumed more diverse diets (urban, 4.1 ± 1.1; rural, 3.5 ± 1; P < 0.01) and had a higher mean FVS (urban, 19.9 ± 5.7; rural, 15.9 ± 4.5; P < 0.01). Both the DDS and FVS were significantly correlated with each other (r = 0.860; P < 0.01) and were positively correlated with MAR, growth, and Hb (P < 0.001) and mother's educational level (P < 0.01). The cutoffs of ≥6.5 (DDS) and ≥17 (FVS) were determined to predict micronutrient adequacy. CONCLUSIONS Both the DDS and FVS can be used interchangeably for assessing growth, health status, and nutritional adequacy. Single cutoff values of the DDS and FVS may aid in prompt identification of children and adolescents with micronutrient inadequacy.

Abstract
Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes pneumonia and lymphopenia. We investigated the predictive value of T-lymphocyte subset absolute counts for outcomes following coronavirus disease-2019 (COVID-19)-associated acute respiratory failure (C-ARF). Patients and methods A retrospective chart review of adult patients with C-ARF was undertaken from 23 March 2020 to 20 November 2021 to obtain relevant data. Patients were divided into two groups based on survival. The T-lymphocyte subsets were determined by flow cytometric analysis. A binomial logistic regression was performed to ascertain factors affecting survival. Cut-off values to differentiate between survivors and non-survivors were identified with the receiver operating characteristic (ROC) analysis. Results A total of 379 patients were analyzed. Age was negatively correlated with survival. Non-survivors had significantly lower T-lymphocyte subset absolute counts than survivors. Serum ferritin levels were significantly higher in non-survivors. Baseline lymphocyte (%) and a subset were predictive of survival in patients [lymphocyte (%) <5.65%, CD3+ <321 cells/µL, CD4+ <205 cells/µL, CD8+ <103 cells/µL]. Conclusions Lower T-lymphocyte subsets were associated with higher mortality in patients with C-ARF. Monitoring trends may help in identifying patients at increased risk of poor outcomes.

Abstract
Background Of the factors influencing severity and outcomes following coronavirus disease-2019 (COVID-19), cellular immune response has a strong impact. The spectrum of response varies from over-activation to hypo-functioning. The severe infection leads to reduction in numbers and dysfunction of T-lymphocytes/subsets. Patients and methods This retrospective, single-center study aimed to analyze the expression of T-lymphocyte/subsets by flow cytometry and inflammation-related biomarker, serum ferritin in real-time polymerase chain reaction (RT-PCR) positive patients. According to oxygen requirements, patients were stratified into nonsevere (room air, nasal prongs, and face mask) and severe [nonrebreather mask (NRBM), noninvasive ventilation (NIV), high-flow nasal oxygen (HFNO), and invasive mechanical ventilation (IMV)] subgroups for analysis. Patients were classified into survivors and nonsurvivors. Mann-Whitney U test was used to analyze differences in T-lymphocyte and subset values when classified according to gender, the severity of COVID, outcome, and prevalence of diabetes mellitus (DM). Cross tabulations were computed for categorical data and compared using Fisher's exact test. Spearman correlation was used to analyze the correlation of T-lymphocyte and subset values with age or serum ferritin levels. p <0.05 values were considered to be statistically significant. Results A total of 379 patients were analyzed. Significantly higher percentage of patients with DM were aged ≥61 years in both nonsevere and severe COVID groups. A significant negative correlation of CD3+, CD4+, and CD8+ was found with age. CD3+ and CD4+ absolute counts were significantly higher in females as compared to males. Patients with severe COVID had significantly lesser total lymphocyte (%), CD3+, CD4+, and CD8+ counts as compared to those with nonsevere COVID (p <0.05). T-lymphocyte subsets were reduced in patients with severe disease. A significant negative correlation of total lymphocyte (%), CD3+, CD4+, and CD8+ counts was found with serum ferritin levels. Conclusions T-lymphocyte/subset trends are an independent risk factor for clinical prognosis. Monitoring may help in intervening in patients with disease progression.

Abstract
BACKGROUND The contagious coronavirus disease-2019 (COVID-19) pandemic has had a significant psychological impact on healthcare workers. Intensive care unit (ICU) and emergency room (ER) providers have functioned in an environment of fear for their health as well as their family well-being. AIM AND OBJECTIVE The aim and objective of the article was to study mental health disorders (anxiety, depression, stress, post-traumatic stress disorder (PTSD), and sleep quality) in frontliners and to identify factors affecting mental health indices. MATERIALS AND METHODS A survey of 153 doctors and nurses working in ICU and ER was conducted from December 2020 to January 2021 using questionnaire with clinically validated scales: Acute Stress Disorder Scale, Perceived Stress Scale, Beck's Depression Inventory (BDI), Zung Self-rating Anxiety Scale (SAS), Global Pittsburgh Sleep Quality Index (PSQI), Multidimensional Scale of Perceived Social Support (MSPS), and New General Self-efficacy (NGSE) Scale. Analysis was performed to identify of gender, age, place of work, self-efficacy, and social support using logistic regression. RESULTS Of the 153 participants, 21.6% had PTSD, 88.6% had moderate to high stress, 16.3% had anxiety, and 59.5% had poor sleep. Of these, the majority were females and those aged ≤30 years. Males had lesser depression, anxiety, and poor sleep compared to females (p <0.05). Participants working in ER reported higher stress as compared to those working in ICU (p <0.05). PTSD, perceived stress, depression, anxiety, and poor sleep were higher in participants with low-to-moderate perceived self-efficacy as compared to participants with high self-efficacy (p <0.05). CONCLUSION This study reveals significant psychological distress among ER and ICU frontliners during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, a typical high-acuity environment during the nonpandemic times.

Abstract
Mumbai was one of the 1st cities in India to go into total lockdown in March 2020. The lockdown was expected to have an influence on eating habits specially the snacking patterns. The main objective of this study was to access the change in snacking patterns of participants living in Mumbai city, India during lockdown. Data was collected in 256 Mumbai residents (60 males, 196 females) using Google forms. Information regarding number of meals consumed, meals at which snacks were consumed, change in snacking pattern, reasons for increase or decrease in snacking, and type of snacks consumed during lockdown as compared to before lock was collected. Around 20% reported a decrease, 31% reported no change and 49% reported an increase in snack consumption during lockdown. Participants consumed higher number of meals during lockdown (p<0.05). Significantly higher percentage of participants did not consume store brought snacks during lockdown (30.9% vs 13.7%) (p<0.05). Significantly higher percentage of participants consumed snacks at mid-evening (50.4% vs 33.6%), late evening (48% vs 32%) and late night (32% vs 16.8%) during lockdown as compared to before lockdown (p<0.05). Significantly change in lemon-water (57.8% vs 43.4%), coffee (47.3% vs 40.6%) and carbonated beverages (14.8% vs 23.4%) was observed during lockdown as compared to before lockdown (p<0.05). Significant increase in nuts (74.2% vs 65.6%), instant noodles (69.5% vs 60.9%) and biscuits (78.5% vs 68%) was observed during lockdown as compared to before lockdown (p<0.05). Significant decrease in South Indian (61.75 vs 69.1%), Frankie (32.8% vs 51.6%), bhel (50.4% vs 69.1%), Chinese bhel (21.5% vs 35.5%) and usal (32% vs 40.2%) was observed during lockdown as compared to before lockdown (p<0.05). To conclude, snacks were consumed at more number of meals during lockdown in comparison to before lockdown. A change in type of snacks consumed was observed during lockdown. Ready and easy to eat snacks such as nuts, instant noodles and biscuits showed an increase whereas snacks that require elaborate cooking procedure showed a decrease in consumption. With partial lockdown still persisting in many parts of the country and many still working from home it is imperative to circulate more accurate information on appropriate snacking habits.

Abstract
Open inguinal lymph node dissection (O-ILND) is the gold standard in the management of lymph nodes in carcinoma penis; however, video endoscopic inguinal lymphadenectomy (VEIL) is performed in some centers. Our primary objective is to compare perioperative and survival outcomes in patients undergoing VEIL with O-ILND, as very few studies have reported long-term survival outcomes till date. We analyzed patients who underwent O-ILND and VEIL (laparoscopic or robot-assisted) from January 2009 to January 2020 in our institute for carcinoma of the penis. Patient details, perioperative complications, and survival outcomes were analyzed. Perioperative outcomes were analyzed by logistic regression and survival outcomes by log-rank and Cox regression methods. We analyzed 79 patients (32 O-ILND, 47 VEIL) with a median follow-up of 51 (IQR 25.5-75.5) and 42 months (IQR 21-62). Wound complications were common in O-ILND group (65.6%) compared to VEIL group (27.7%) (p = 0.001), predominantly skin flap necrosis in 14 groins (23.73%) after O-ILND and none after VEIL. Median overall survival was 80 and 88 months (p = 0.840) with five-year survival of 65% and 66.8% (p = 0.636) and five-year DSS of 76.6% and 73.9% (p = 0.96) in O-ILND and VEIL, respectively. Multivariate analysis showed that grade and pathological node status were significant (HR-2.650, p = 0.040; HR-3.218, p = 0.024) factors for survival. The retrospective nature of the study design is the limitation. Management of inguinal lymph nodes in carcinoma penis by VEIL is safe, associated with lesser wound-related complications, and equivalent survival outcomes compared to O-ILND. It should be considered as an alternative option for inguinal lymph node dissection.

Abstract
OBJECTIVE To cross-calibrate dual energy X-ray absorptiometry machines when replacing GE Lunar DPX-Pro with GE Lunar iDXA. METHODS A cross-sectional study was conducted in 126 children (3-19 years) and 135 adults (20-66 years). Phantom cross calibration was carried out using aluminum phantom provided with each of the machines on both machines. Total body less head (TBLH), lumbar spine (L2-L4) and left femoral neck bone mineral density (BMD), bone mineral content (BMC), and bone area were assessed for each patient on both machines. TBLH lean and fat mass were also measured. Bland-Altman analysis, linear regressions, and independent sample t test were performed to evaluate consistency of measurements and to establish cross-calibration equations. RESULTS iDXA measured 0.33% lower BMD and 0.64% lower BMC with iDXA phantom as compared to DPX-Pro phantom (p < 0.001). In children, TBLH-BMC, femoral BMC and area were measured 10%-14% lesser, TBLH area was higher by 1%-2% and L2-L4 area by 10%-14% by iDXA as compared to DPX-Pro. iDXA measured higher TBLH fat [15% (girls), 31% (boys)] than DPX-Pro. In adults, TBLH-BMD (1.7%-3.4%), BMC (6.0%-10.9%) and area (4.2%-7.6%) were measured lesser by iDXA than DPX-Pro. L2-L4 BMD was higher [2.7% (men), 1.8% (women)] by iDXA than DPX-Pro. Femoral BMC was 2.11% higher in men and 4.1% lower in women by iDXA as compared to DPX-Pro. In children, R2 of cross-calibration equations, ranged from 0.91 to 0.96; in adults, it ranged from 0.93 to 0.99 (p < 0.01). After the regression equations were applied, differences in BMD values between both machines were negligible. CONCLUSION A strong agreement for bone mass and body composition was established between both machines. Cross-calibration equations need to be applied to transform DPX-Pro measurements into iDXA measurements to avoid errors in assessment. This study documents a need for use of cross-calibration equations to transform DPX-Pro body composition data into iDXA values for clinical diagnosis.

Abstract
Our aim is to describe changes in the muscle-bone unit assessed as a ratio of bone mineral content (BMC) to lean body mass (LBM) through puberty at total body and various skeletal sites in Indian boys and girls. A cross-sectional study was conducted (888 children, 480 boys, aged 5-17 years) in Pune, India. Pubertal staging was assessed. BMC, LBM and fat percentage at the arms, legs, android, gynoid and total body (less the head) were assessed by dual energy X-ray absorptiometry. The amount of BMC per unit LBM (BMC/LBM) was computed. Changes in mean BMC/LBM at 5 Tanner (pubertal) stages after adjustment for age and fat percentage were calculated. In boys, adjusted BMC/LBM was significantly higher with successive Tanner stages [legs (TS-II vs TS-I), android (TS-III vs TS-II, TS-IV vs TS-III) and gynoid region (TS-III vs TS-II and TS-II vs TS-I) (p < 0.05)]. In girls, adjusted BMC/LBM was significantly higher with successive Tanner stages at total body, legs and gynoid (TS-III vs TS-II; TS-II vs TS-I; TS-V vs TS-IV), arms (TS-I to TS-V) and android regions (TS-V vs TS-IV) (p < 0.05). Boys had significantly higher adjusted BMC/LBM than girls at earlier Tanner stages (TS-I to TS-III), whereas girls had significantly higher adjusted BMC/LBM than boys at later Tanner stages (TS-IV, TS-V) (p < 0.05). Indian boys and girls showed higher total and regional body, and age- and fat percentage-adjusted BMC/LBM with successive pubertal stages. Girls had higher BMC/LBM than boys which may possibly act as a reservoir for later demands of pregnancy and lactation.

Abstract
This cross-sectional study, to assess bone health in Indian overweight, obese children in comparison with healthy controls was conducted in 245 (126 girls) children and adolescents aged 6-17 y in Pune, India. It was found that total body bone mineral content, bone area and bone mineral density adjusted for Tanner stage and weight were significantly lower in obese children as compared to overweight children, which in turn, was significantly lower than normal weight children (p < 0.05). Thus, overweight and obesity is negatively related to bone health in children and adolescents. Interventions need to be planned to increase peak bone mass accrual in overweight and obese children to reduce future risk of fracture and osteoporosis.

Abstract
OBJECTIVE To examine the association of vitamin D receptor (VDR) gene polymorphisms of the Fok1 locus on bone mass accrual in Indian girls used to a low calcium intake. METHODS An intervention trial was undertaken in 102 girls aged 8-16 y, attending a state run school in Pune city, India. All girls received 500 mg calcium daily and 30,000 IU of vitamin D3 quarterly for one year. Dietary calcium intake was evaluated. Bone mineral content (BMC), bone area (BA) and bone mineral density (BMD) were measured at total body using Dual Energy X-ray Absorptiometry (Lunar DPX-PRO). Polymorphisms of the Fok1 locus of the vitamin D Receptor (VDR) gene were detected using SYBR Green quantitative polymerase chain reaction. RESULTS The prevalence of Fok1 polymorphism was 43.1% (Ff), 9.8% (ff) and 47.1% (FF). At baseline, FF genotype had significantly lower BMD as compared to ff and Ff genotype (p < 0.05). At baseline, majority of girls (82.4%) were hypocalcemic with low calcium intake. Post-supplementation, FF genotype had significantly lower bone mass as compared to ff and Ff genotype. Significant increase in BMC [Ff (17.9%); ff (18.1%); FF (17.4%)], and BMD [Ff (5.4 %); ff (6.3%); FF (4.8%)] was observed post supplementation (p value < 0.05), though percentage increase in BMC and BMD was similar for three Fok1 polymorphisms (p > 0.1). CONCLUSIONS VDR gene polymorphism, as defined by Fok1 genotype had no positive influence on bone mass accrual in response to calcium supplementation.

Abstract
To study the association between vitamin D receptor (VDR) gene polymorphisms and bone mass indices in adolescent girls, a cross-sectional study was conducted in 120 post-menarchal girls aged 15-18 years in Pune city, India. Serum levels of ionised calcium, inorganic phosphorous, parathyroid hormone and 25-hydroxy vitamin-D were measured. Bone mineral content (BMC), bone area (BA) and bone mineral density (BMD) were measured at total body (TB), lumbar spine (LS) and left femoral neck (FN) using dual energy X-ray absorptiometry. Polymorphisms of the VDR gene at the Fok1 and Bsm1 loci were detected using SYBR Green quantitative polymerase chain reaction. The overall distribution of genotypes at the Bsm1 locus in this study was 33.3 % Bb, 29.2 % bb and 37.5 % BB while that for the Fok1 locus was 44.2 % Ff, 7.5 % ff and 48.3 % FF. There were no significant differences in the blood parameters when classified according to Bsm1 or Fok1 genotypes. Subjects with BB genotype have significantly higher mean TBBMC, TBBA, TBBMD and LSBMD than Bb and bb (p < 0.05) and showed a tendency for association with LSBMC and LSBA (p < 0.1). Subjects with Ff genotype showed a tendency for association with left FNBMC and FNBA (p < 0.1). Bsm1 genotype did not show an association with FN bone indices whereas Fok1 genotype did not show association with TB or LS bone indices. In conclusion, the present study demonstrates VDR gene polymorphism, defined by Bsm1 genotype, has an influence on total body and lumbar spine bone mass indices in post-menarchal Indian girls.

Abstract
Micronutrient deficiencies are common consequences of the plant-based diet in children from developing countries which may affect their linear and ponderal growth. The aim of the study was to investigate the association between micronutrient status and growth indices in Indian girls. In cross-sectional studies (2006-2010), data on weight, height and diet were collected on 1302 girls (2-18 years) from Pune city, India. Fasting hemoglobin was measured on 1118 girls and serum zinc was measured on 695 girls. Height-for-age Z-scores (HAZ) and body mass index for age Z-score (BMIZ) were computed using contemporary Indian references. HAZ >-1 was observed in 54% girls, and 18.1% were short (HAZ <-2). BMIZ was within the reference range (-2<BMIZ<2) in majority (82.4%) of the girls. Average HAZ and BMIZ were significantly higher in higher socioeconomic (HSE) than in middle (MSE) and lower (LSE) socioeconomic groups (p<0.05). Girls in all age groups had calcium, zinc, iron and vitamin intakes of <50% of Indian recommended dietary intakes. Mean nutrient intakes were significantly higher in HSE than in MSE and LSE girls (p<0.05). Girls with short stature (HAZ <-2) had significantly lower intakes of calcium, zinc, iron, β-carotene, riboflavin, niacin, folate and ascorbic acid (p<0.05). Higher levels of serum zinc and hemoglobin were observed in girls with HAZ >-1 than in short girls even after adjusting for socioeconomic status (SES). The mean serum zinc level of thin girls (BMIZ <-2) was significantly lower than those of both normal and overweight girls after adjusting for SES. Micronutrient sufficiency is of paramount importance for adequate growth in Indian girls.

Abstract
BACKGROUND Toddlers in Pune, India, accustomed to low dietary calcium intake but vitamin D replete have low serum ionised calcium and inappropriately raised serum inorganic phosphorus concentrations together with elevated serum parathyroid hormone (PTH) concentrations. We hypothesised that dietary calcium deficiency leads to end organ resistance to PTH, thus resulting in mild hypocalcaemia and hyperphosphataemia, and that this would be reversed by oral calcium supplementation. METHODS 51 subjects (25 male; mean (SD) age 2.4 (0.8) years) from an urban slum in Pune were randomised to 500 mg of oral calcium supplement or placebo, daily, for 8 weeks. All subjects received 20 mg of oral elemental iron, daily, as 90% had a serum ferritin concentration <12 microg/l. All subjects were examined for clinical stigmata of rickets and had a wrist radiograph performed. Serum concentrations of ionised calcium, phosphorus, PTH and fibroblast growth factor-23 (FGF-23) were measured at the start and end of the trial. RESULTS No subject had clinical or radiological evidence of rickets. There was a significant increase in mean serum ionised calcium concentration (p<0.001) in the supplemented but not the placebo group (p = 0.32). The decrease in mean serum phosphorus concentration in the supplemented group was greater (p<0.001) than in the placebo group (p = 0.003). Mean serum PTH fell in the calcium supplemented (p = 0.001) but not in the placebo (p = 0.303) group. The mean serum FGF-23 concentration did not change in response to calcium supplementation. CONCLUSIONS From these data the authors conclude that low dietary calcium intake is associated with resistance to PTH.
