Estimation of dietary intake of sodium, potassium, phosphorus and protein in healthy Indian population and patients with chronic kidney disease.

Introduction: Poor nutritious diet is a major risk element for non-communicable diseases (NCD), which are of considerable public health concern. Given the diverse dietary patterns in India, precise determination of nutrient consumption is crucial for disease management. The present study assessed the dietary intake of sodium, potassium, protein, and phosphorus among North Indians. Methods: This cross-sectional study included healthy adults and adults with stage 2 to 4 chronic kidney disease (CKD). We analysed sodium, protein, potassium and phosphorus intakes using one-time 24-h urinary excretion. Dietary intake was also analysed in subgroups based on sex, body mass index, blood pressure and abdominal obesity. We evaluated the performance of various equations available to estimate sodium intake using a spot urine sample with respect to the sodium excretion measured in a 24-h urine sample. Descriptive statistics was used along with t-test for statistical significance. Results: A total of 404 subjects (182 adult healthy subjects and 222 adults with CKD) with a mean age of 47.01 ± 11.46 years were studied. Mean dietary intakes of sodium, salt, potassium, protein and phosphorus were 2.94 ± 1.68 g/day, 7.42 ± 4.24 g/day, 1.43 ± 0.59 g/day, 47.67 ± 14.73 g/day and 0.86 ± 0.39 g/day, respectively. There were no differences in nutrient consumption between adults who were healthy and those with CKD. Consumption of sodium, salt, protein, potassium, and phosphorus among healthy population vs. those with CKD were 2.81 ± 1.60 vs. 3.05 ± 1.73 g/day (p = 0.152), 7.08 ± 4.04 vs. 7.70 ± 4.37 g/day (p = 0.143), 47.16 ± 14.59 vs. 48.08 ± 14.86 g/day (p = 0.532), 1.38 ± 0.59 vs. 1.48 ± 0.58 g/day (p = 0.087) and 0.86 ± 0.41 vs. 0.87 ± 0.37 g/day (p = 0.738), respectively. Men had higher consumption of these nutrients than women. Compared to non-hypertensives, hypertensive subjects had higher consumption of salt (8.23 ± 4.89 vs. 6.84 ± 3.59 g/day, p = 0.002) and potassium (1.51 ± 0.63 vs. 1.38 ± 0.55 g/day, p = 0.024), however, no difference were found in protein and phosphorus intakes. In terms of performance of equations used to estimate 24-h sodium intake from spot urinary sodium concentration against the measured 24-h urinary sodium excretion, INTERSALT 2 equation exhibited the least bias [1.08 (95% CI, -5.50 to 7.66)]. Conclusion: The study shows higher-than-recommended salt and lower-than-recommended potassium intake in the north Indian population compared to those recommended by guidelines. The dietary protein intake is below the recommended dietary allowance. These findings help the development of targeted policies for dietary modification to reduce the risk of the development and progression of CKD.

Determinants of polycystic ovary syndrome: A matched case-control study.

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a multifaceted endocrine disorder of women of reproductive age with a multifactorial aetiology. Despite much research, there is still inconclusive data on the impact of dietary, lifestyle and socio-economic factors on PCOS aetiology. Thus, the present study explored the association of PCOS with diet, eating behaviour, other lifestyle and socio-economic factors. METHODS: A matched-pair case-control study was conducted on 150 women with PCOS and 150 healthy controls. Information on diet, eating behaviour and physical activity, and also anthropometric and socio-economic data were collected through standard questionnaires. The adjusted odds ratios (AmOR) were calculated and reported using conditional multivariable logistic regression. RESULTS: The results showed low education level (AmOR = 8.44; 95% confidence interval [CI] = 1.63-43.68), high sugar consumption (AmOR = 11.61; 95% CI = 2.05-65.72) along with higher body mass index (BMI) and inactivity to be significantly associated with PCOS. Also, a significant protective effect was found for cognitive dietary restraint (AmOR = 0.79; 95% CI = 0.66-0.93), crude fibre (AmOR = 0.61; 95% CI = 0.45-0.82) and protein intake. CONCLUSIONS: Low education status may contribute to higher receptiveness to choosing unhealthy diets and lifestyles, resulting in adiposity and an increased risk of PCOS.

Assessment of quality of life in patients having Poly-Cystic Ovarian Syndrome: A cross-sectional facility-based study.

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a complex and heterogeneous disorder affecting various body organs. Menstrual irregularity, anovulation, and many cosmetic issues faced by PCOS patients endanger the essence of being a woman and may have a deleterious impact on their health-related quality of life (HRQOL). This study aimed to assess HRQOL in patients with PCOS and to identify the clinical and socio-demographic factors that might predict poor HRQOL. MATERIALS AND METHODS: This cross-sectional study was carried out in the tertiary care hospital in India. A total of 275 women visiting the same setting and diagnosed with PCOS were included. The participants' quality of life was studied using a disease-specific HRQOL questionnaire. Information regarding clinical and socio-demographics was collected using the interviewer schedule. For evaluating the predictors of HRQOL in PCOS subjects, analysis of variance and independent t-test was applied. For subgroup analysis, the post hoc (Gabriel) test was applied. RESULTS: The average total score of HRQOL of the study participants was 125.41 ± 29.1. The lowest weighted mean score was for menstrual problems. Among the socio-demographic variables, age and educational level influenced the HRQOL scores. Highly educated women reported the poorest HRQOL. The analysis of variance also indicated a significant variation in HRQOL scores among body mass index categories [F (4,270) = 5.09, P = <.001] and hirsutism status [F (2,272) = 14.222, P =<.001]. CONCLUSIONS: Menstrual irregularity, hirsutism, increased body mass index, educational status, and age are critical in altering HRQOL in PCOS cases. Clinicians should inquire about the HRQOL of patients with severe clinical manifestations and appropriate support must be provided during patient care.

Treatment seeking behavior among patients with polycystic ovarian syndrome (PCOS)-A cross-sectional study from Northern India.

BACKGROUND: Polycystic ovarian syndrome (PCOS) has now become a common problem among adolescent girls and young women in India. However, little is known about the treatment and satisfaction incurred from it. Our study aimed to assess the treatment-seeking behaviour among patients with PCOS. MATERIALS AND METHODS: The cross-sectional study was carried out in gynecology OPD of PGIMER, Chandigarh. Women with PCOS, 275, visiting the gynecology OPD were included. The treatment-seeking behavior for PCOS was elucidated among cases using a questionnaire. This included parameters like healthcare consulted, preferred system of medicine, referral pattern, treatment efficacy, and expenses incurred. Univariate descriptive analysis was used to present the results. RESULTS: The majority (68%) of the study participants were less than 25 years of age. The average weight was 66.78 (±13.0) Kg. Half of the participants were students. More than 70% belonged to the upper or upper-middle class. The study participants were diagnosed with PCOS at an average age of 21.4 (±4.7) years. The minimum age reported at diagnosis was 11 years, and the maximum age of diagnosis was 36 years. Most respondents preferred Allopathic treatment followed by homeopathy and Ayurveda. Few also opted for other treatment choices like diet therapy, yoga & meditation, weight loss supplements, and home remedies. Treatment efficacy ranged between 17.3%-34.2%. The majority of respondents reported the treatment to be moderately expensive. Most respondents (58.91%) were hardly influenced, while 16% were quite influenced by PCOS medicine or treatment advertisements. CONCLUSION: PCOS patients opt for different treatment options but generally find the treatment less effective and expensive.

Home-based intensive nutrition therapy improves frailty and sarcopenia in patients with decompensated cirrhosis: A randomized clinical trial.

BACKGROUND AND AIM: The majority of patients with decompensated cirrhosis suffer from malnutrition, a potentially modifiable contributor to frailty and sarcopenia. The present study investigated the impact of a 6-month dietician-supported home-based intensive nutrition therapy (HINT) intervention on objective frailty and sarcopenia metrics in patients with decompensated cirrhosis. METHODS: One hundred adult patients with decompensated cirrhosis, frailty, and sarcopenia at baseline were randomized 1:1 to receive standard medical therapy (SMT) plus HINT (intervention) versus SMT (control) alone. The primary outcome was an improvement in frailty as measured by the liver frailty index (LFI). Secondary outcome measures included sarcopenia metrics, liver disease severity scores, hospitalization, and death. RESULTS: The LFI improved more in the intervention arm as compared with controls (0.8 vs 0.4; P < 0.001). Baseline and end-of-study skeletal muscle index (SMI) was available in a subset of 32 male patients, with greater improvements seen in the intervention arm compared with controls (6.36 vs 0.80; P = 0.02). Patients in the intervention arm had less hospitalizations over the 6-month follow-up (19 [38%] vs 29 [58%]; P = 0.04). On subgroup analysis, in the 64% of patients who were adherent to calorie and protein intake targets at 6 months, significant improvement was seen in liver disease severity scores and survival (P < 0.05). CONCLUSION: In patients with decompensated cirrhosis, frailty, and sarcopenia, a 6-month dietitian-supported home-based intensive outpatient nutrition therapy was associated with statistically and clinically relevant improvement in frailty. The subgroup of adherent patients showed improvement in their liver disease scores and reduction in mortality. These findings support the key role of food as medicine in the management of cirrhosis.

Efficacy of multi-strain probiotic along with dietary and lifestyle modifications on polycystic ovary syndrome: a randomised, double-blind placebo-controlled study.

PURPOSE: Effect of multi-strain probiotic along with dietary and lifestyle modifications in the management of polycystic ovary syndrome (PCOS) has rarely been reported. We thus aimed to investigate the effect of multi-strain probiotic (Lactobacillus acidophilus UBLA-34, L. rhamnosus UBLR-58, L. reuteri UBLRu-87 (each of 2 billion colony forming units (CFU)); L. plantarum UBLP-40, L. casei UBLC-42, L. fermentum UBLF-31, Bifidobacterium bifidum UBBB-55 (each of 1 billion CFU) and fructo-oligosaccharides (100 mg)) and dietary and lifestyle modifications on restoration of menstrual regularity, weight reduction, metabolic and hormonal profile in women with PCOS. METHODS: A 104 participants (age 18-40 years) were randomly allocated to receive probiotic or placebo capsules for 6 months. Baseline and end line assessment were performed for menstrual cycle regularity, ultrasonography scan for ovaries, total testosterone, dehydroepiandrosterone (DHEAS), insulin, luteinizing hormone/follicle stimulating hormone (LH/FSH) ratio, fasting blood sugar (FBS), homeostatic model assessment-insulin resistance (HOMA-IR), weight reduction, waist-/hip circumference (WC, HC), waist to hip ratio (WHR), and body mass index (BMI). Plasma lipopolysaccharide and effect of intervention on quality of life was investigated. Diet and exercise were controlled during the trial. RESULTS: Probiotic supplement along with dietary and lifestyle modifications significantly regularised menstrual cycle (p 0.023), improved levels of total testosterone (p 0.043), WC (p 0.030), WHR (p 0.027) and menstrual domain of quality of life (p 0.034) as compared to placebo. No adverse events related to study were reported. CONCLUSION: Multi-strain probiotic along with dietary and lifestyle modifications were effective in the management of PCOS.

Existing creatinine-based equations overestimate glomerular filtration rate in Indians.

BACKGROUND: Accurate estimation of glomerular filtration rate (GFR) is important for diagnosis and risk stratification in chronic kidney disease and for selection of living donors. Ethnic differences have required correction factors in the originally developed creatinine-based GFR estimation equations for populations around the world. Existing equations have not been validated in the vegetarian Indian population. We examined the performance of creatinine and cystatin-based GFR estimating equations in Indians. METHODS: GFR was measured by urinary clearance of inulin. Serum creatinine was measured using IDMS-traceable Jaffe's and enzymatic assays, and cystatin C by colloidal gold immunoassay. Dietary protein intake was calculated by measuring urinary nitrogen appearance. Bias, precision and accuracy were calculated for the eGFR equations. RESULTS: A total of 130 participants (63 healthy kidney donors and 67 with CKD) were studied. About 50% were vegetarians, and the remainder ate meat 3.8 times every month. The average creatinine excretion were 14.7 mg/kg/day (95% CI: 13.5 to 15.9 mg/kg/day) and 12.4 mg/kg/day (95% CI: 11.2 to 13.6 mg/kg/day) in males and females, respectively. The average daily protein intake was 46.1 g/day (95% CI: 43.2 to 48.8 g/day). The mean mGFR in the study population was 51.66 ± 31.68 ml/min/1.73m2. All creatinine-based eGFR equations overestimated GFR (p < 0.01 for each creatinine based eGFR equation). However, eGFR by CKD-EPICys was not significantly different from mGFR (p = 0.38). The CKD-EPICys exhibited lowest bias [mean bias: -3.53 ± 14.70 ml/min/1.73m2 (95% CI: -0.608 to -0.98)] and highest accuracy (P30: 74.6%). The GFR in the healthy population was 79.44 ± 20.19 (range: 41.90-134.50) ml/min/1.73m2. CONCLUSION: Existing creatinine-based GFR estimating equations overestimate GFR in Indians. An appropriately powered study is needed to develop either a correction factor or a new equation for accurate assessment of kidney function in the Indian population.

Effectiveness of an intervention package on knowledge, attitude, and practices of food handlers in a tertiary care hospital of north India: A before and after comparison study.

BACKGROUND: Food-borne illnesses have been a recognized hazard for decades. Recent promulgation of Food Safety and Standards Act (FSSA), 2006, indicates the concern of our Govt. for food safety. Research on effectiveness of food safety interventions in our country is remarkably scarce. Hence, the present study was conducted in a tertiary care hospital of north India to create evidence-based results for food safety interventions. METHODS: The study was before and after intervention trial which was registered with CTRI. Data collection was paperless using a software. All food handlers (n = 280) working inside the hospital were recruited. Intervention package comprised Self-Instructional Manual in Hindi for food handlers, short film for sensitization of food handlers on food safety titled 'Gravy Extra', and a documentary titled 'Food Safety from farm to Fork'. Chi square test, paired t test, and Wilcoxon sign rank test were used. RESULTS: The mean age of food handlers was 35 ± 2 years. Majority (61.7%) of food handlers were educated less than 10th standard. Nearly 60% of them had up to five years of experience. At base line majority (68.9%) had a fair knowledge about food safety issues. There was a significant improvement in food safety knowledge and practice score of food handlers after the intervention (p < 0.05). Their attitude toward food safety changed in a positive direction (p < 0.05). CONCLUSION: The intervention package was useful in improving the knowledge, creating a positive attitude and enhancing the food safety practices of food handlers working inside a tertiary care hospital.

Dietary antioxidents and oxidative stress in predialysis chronic kidney disease patients.

CONTEXT: Dietary antioxidants are important in protecting against human diseases. Oxidative stress, a non- traditional risk factors of cardio-vascular disease is far more prevalent in chronic kidney disease (CKD) patients than in normal subjects. EVIDENCE ACQUISITIONS: Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science have been searched. RESULTS: Oxidative stress could be a consequence of an increase in reactive oxygen species as well as a decrease in antioxidant defenses. Among the important factors that can be involved in triggering oxidative stress is insufficient dietary intake of antioxidants. Malnourished CKD patients are reported to have more oxidative stress than well nourished ones. CONCLUSIONS: Moving beyond the importance of assessment of dietary protein and energy in pre dialysis CKD patients to the assessment of dietary antioxidants is of utmost importance to help combat enhanced oxidative stress levels in such patients.
