Pelvic fracture urethral injury in adolescents - Predictors of outcomes and surgical complexity.

INTRODUCTION: Pelvic fracture urethral injury (PFUI) is more severe in younger individuals. The adolescent group is prone to protracted morbidity due to severity of the injury and its impact on lifestyle. Hence, treatment options and data on outcomes are crucial in planning management. The adolescents are a subgroup in several series of PFUI, but literature exclusively studying this group is sparse. MATERIALS & METHODS: A retrospective review of all adolescents (aged between 10 and 19 years as defined by WHO) who underwent surgical repair for PFUI between January 2005 and December 2019 was conducted. Success was defined as a bell-shaped urine flow curve and Qmax of >15 ml/s, no evidence of re-stricture (on cystoscopy/MCU), and no re-intervention. Measurements of the length of the urethral defect and bulbar urethra were done using a digital scale by the radiologist from micturating cystourethrogram (MCU). The Gapometry/Urethrometry (GU) index was calculated as the ratio of the length of the urethral defect to that of the bulbar urethra. Data was analysed using SPSS software version 20.0 and Stata Version 16. The primary outcome was the success of anastomotic urethroplasty. Secondary outcomes were evaluating factors predicting operative complexity (simple perineal versus elaborate perineal approach). RESULTS: We studied 22 patients, out of which 8 were referred following prior failed intervention elsewhere. The mean age was 16.5 + 2.7 years. All the patients were treated using a perineal approach with an overall success rate of 90.9%. Two patients had a failure and were managed with Endoscopic Internal Urethrotomy (EIU), and urethral dilatation. The median follow-up was 24 months. All 8 patients with prior failed interventions had a successful outcome. Twelve patients required inferior pubectomy (elaborate perineal approach). The median length of the urethral defect (2.3 cm IQR- 1.45,3.30 vs. 1 cm, IQR-0.65, 1.6) and the mean GU index (0.45 ± 0.18 cm vs. 0.25 cm ± 0.12 cm) were significantly higher in those who required an elaborate perineal approach. CONCLUSIONS: The perineal approach for surgical repair (anastomotic urethroplasty) of pelvic fracture urethral injury has a favourable success rate of 90.9% in adolescents. Re-do anastomotic urethroplasty for prior failed repairs also had a high success rate of 100%. Cases requiring an elaborate perineal approach were associated with a significantly higher Gapometry/Urethrometry Index (>0.45) and length of the urethral defect (>2.3 cm). This information may assist in patient counselling and preparation for additional steps during repair.

Morphometric Analysis of the Neural Arch of C2 Vertebra in Indian Population.

BACKGROUND AND OBJECTIVE: The most common injuries to upper cervical spine are fractures of the second cervical vertebrae. The study aims to evaluate the morphometry of the neural arch of the second cervical vertebrae in the South Indian population. MATERIALS AND METHODS: Sixty-three second cervical vertebrae of undetermined gender and age without any gross defect were used for the study. The dimensions of neural arch, including superior articular facet, inferior articular facet, pediculoisthmic component, lamina, spinous process, foramen transversarium, and vertebral foramen, were measured by two independent observers using digital vernier caliper accurate to 0.1 mm and the data was analyzed. Descriptive statistics were obtained for the variables. Paired t-test was done to compare the measurements between right and left sides. RESULTS: There was no statistical difference between the right and left sides of the dimensions of superior articular facets, foramen transversarium, and the transverse diameter of inferior articular facet. The anteroposterior diameter of the inferior articular facets was more on the right side (P = 0.009). The width of the pediculoisthmic component in both the superior and inferior aspects was found to be less on the right side than that of the left (P = 0.006 and P = 0.031, respectively). The thickness in the middle one-third of laminae was optimum for bilateral safe screw insertion (≥4.0 mm) in 77% specimens. CONCLUSION: In summary, measurements of the transverse diameter of superior articular facet and thickness of lamina differed significantly from those reported in literature. This should be kept in mind while doing neurosurgery procedures in the Indian population.

Modeling Zero-inflated Count Data Using Generalized Poisson and Ordinal Logistic Regression Models in Medical Research.

Objectives: In medical research, the study's design and statistical methods are pivotal, as they guide interpretation and conclusion. Selecting appropriate statistical models hinges on the distribution of the outcome measure. Count data, frequently used in medical research, often exhibit over-dispersion or zero inflation. Occasionally, count data are considered ordinal (with a maximum outcome value of 5), and this calls for the application of ordinal regression models. Various models exist for analyzing over-dispersed data such as negative binomial, generalized Poisson (GP), and ordinal regression model. This study aims to examine whether the GP model is a superior alternative to the ordinal logistic regression (OLR) model, specifically in the context of zero-inflated Poisson models using both simulated and real-time data. Methods: Simulated data were generated with varied estimates of regression coefficients, sample sizes, and various proportions of zeros. The GP and OLR models were compared using fit statistics. Additionally, comparisons were made using real-time datasets. Results: The simulated results consistently revealed lower bias and mean squared error values in the GP model compared to the OLR model. The same trend was observed in real-time datasets, with the GP model consistently demonstrating lower standard errors. Except when the sample size was 1000 and the proportions of zeros were 30% and 40%, the Bayesian information criterion consistently favored the GP model over the OLR model. Conclusions: This study establishes that the proposed GP model offers a more advantageous alternative to the OLR model. Moreover, the GP model facilitates easier modeling and interpretation when compared to the OLR model.

Trends in prevalence and determinants of severe and moderate anaemia among women of reproductive age during the last 15 years in India.

BACKGROUND: Anaemia is a serious global public health problem that disproportionally affects children, adolescent girls, and women of reproductive age, especially pregnant women. Women of reproductive age are more vulnerable to anaemia, particularly severe and moderate anaemia leads to adverse outcomes among pregnant women. Despite continuous Government efforts, anaemia burden still poses a serious challenge in India. The objective of this study is to assess the trends in prevalence and determinants of severe and moderate anaemia among women of reproductive age between 15 and 49 years. METHOD: We used three rounds of the large-scale National Family Health Survey (NFHS) India, conducted on a representative sample of households using a cross-sectional design across the country in 2005-06, 2015-16 and 2019-2021. We included all the women aged 15 to 49 years in our analysis. We used the same haemoglobin (Hb) cut-off values for all the three rounds of surveys to ensure comparability. Generalized linear regression analyses with log link were done. Survey weights were incorporated in the analysis. RESULTS: The prevalence of severe or moderate Anaemia (SMA) in non-pregnant women was 14.20%, 12.43% and 13.98%; it was 31.11%, 25.98% and 26.66% for pregnant women in 2006, 2016 and 2021 respectively. The decline in SMA prevalence was 1.54% in non-pregnant women, whereas it was 14.30% in pregnant women in 15 years. Women who were poor, and without any formal education had a higher risk for severe and moderate Anaemia. CONCLUSION: Despite the intensive anaemia control program in India, SMA has not declined appreciably in non-pregnant women during the last two decades. Despite the decline, the prevalence of SMA was about 26% in pregnant women which calls for a comprehensive review of the existing anaemia control programmes and there must be targeted programmes for the most vulnerable and high-risk women such as rural, poor and illiterate women of reproductive age to reduce the burden of anaemia among them.

Exact correction factor for estimating the OR in the presence of sparse data with a zero cell in 2 × 2 tables.

In case-control studies, odds ratios (OR) are calculated from 2 × 2 tables and in some instances, we observe small cell counts or zero counts in one of the cells. The corrections to calculate the ORs in the presence of empty cells are available in literature. Some of these include Yates continuity correction and Agresti and Coull correction. However, the available methods provided different corrections and the situations where each could be applied are not very apparent. Therefore, the current research proposes an iterative algorithm of estimating an exact (optimum) correction factor for the respective sample size. This was evaluated by simulating data with varying proportions and sample sizes. The estimated correction factor was considered after obtaining the bias, standard error of odds ratio, root mean square error and the coverage probability. Also, we have presented a linear function to identify the exact correction factor using sample size and proportion.

Study protocol: 'a large cohort study of postnatal events in a not-for-profit referral centre in Vellore, South India'.

INTRODUCTION: In a large developing country, with diverse population characteristics and differential access to healthcare, it is important to identify factors that influence postnatal health. This knowledge will help frame recommendations to enhance universal postnatal care. METHODS AND ANALYSIS: A prospective cohort study will be conducted by recruiting all participants who deliver in a referral centre in South India during a 1-year period after written consent is obtained from them. In addition to clinical information pertaining to their delivery and demographics, details of physical health, mental health socioeconomic status and emotional support will also be collected. Every participant will be followed up physically and/or by telephonic consultation at 3, 9 and 18 months of their postnatal period to reassess their status and that of their babies. As there are several independent and dependent variables requiring multivariate analysis, a sample size of 10 000 is considered adequate. Any unplanned visits to a health facility will be enquired into and documented for analysis.During data analysis, the effect of Caesarean section, high-risk characteristics and gestational age of the baby at delivery on various outcome measures and postnatal status will be evaluated. Interpretation of the large volume of collected data will help frame recommendations to improve postnatal care ETHICS AND DISSEMINATION: The study is approved by the Institutional Review Boards (Research and Ethics Committees) of Christian Medical College, Vellore, Tamil Nadu, India (IRB 12178 date 24 June 2020).Women are provided with a detailed information sheet and written consent is obtained. They are reassured that their care will not be compromised if they do not consent to the study. Data will be available on the clinical trial portal to assist in the dissemination of results after the project is published. TRIAL REGISTRATION NUMBER: CTRI/2022/03/041343.

Prevalence and Factors Affecting Difficult Intravenous Access in Children in Oman: A Cross-sectional Study.

Objectives: Peripheral intravenous (IV) access is a standard procedure in clinical settings. Nevertheless, previous studies have indicated that difficult peripheral IV access is prevalent in children. This study aimed to determine the prevalence and factors contributing to difficult peripheral IV cannulation in children admitted to a tertiary care hospital in Oman. Methods: This cross-sectional study was conducted from September to December 2015 at Sultan Qaboos University Hospital in Muscat, Oman. Nurses collected data concerning factors contributing to difficult IV access in children. Results: A total of 511 children undergoing cannulation during the study period were included in the analysis. Overall, 23.3% of the children experienced two or more cannulation attempts. The study identified three variables associated with successful cannulation in cases of difficult IV access. Visible veins were 2.72-times (95% CI: 1.58-4.68) more likely to be associated with success (p < 0.001), while palpable veins were 2.22-times (95% CI: 1.29-3.83) more likely to be associated with success (p = 0.004). However, scarring from previous IV access attempts was half (95% CI: 0.31-0.77) as likely to be associated with successful cannulation (p = 0.002). Conclusions: We identified statistically significant variables related to difficult IV cannulation in children, which we used to develop a prediction tool to assess the likelihood of difficult IV access in pediatric patients. Further research is necessary to validate the use of the difficult IV access prediction tool in this population.

Impact of exclusive breast feeding until six months of age on common illnesses: A prospective observational study.

Objectives: The WHO recommends exclusive breast feeding (EBF) for all infants for the first six months of life. National Family Health Survey-4 (2015-16) shows EBF rates of only 54.9%. We conducted a prospective study to assess prevalence of EBF and incidences of illnesses in infants from birth till six months of age. Methods: Healthy term infants born in our hospital between December 2017 and November 2018 were recruited at birth. Structured diary cards were given to mothers to record feeding patterns, occurrence and severity of illnesses. Mothers were interviewed at 6, 10, 14 and 26 weeks or contacted by telephone at 18 and 22 weeks. Data were analyzed using SPSS IBM Statistics 22. Results: The prevalence of EBF among 450 infants (M:F = 1.3:1) who completed the study was 47% at 6 months. 185 (69 EBF + 116 non-EBF) of 450 infants reported a total of 242 illnesses, most commonly respiratory (82.6%) followed by gastrointestinal (11.6%). Number of illnesses per infant was 0.45 and 0.6 in EBF group and non-EBF group respectively (p = 0.015). Illness incidences in EBF infants were significantly lower during all successive time intervals after 10 weeks of age. Logistic regression analysis confirmed significantly lower illness incidences in EBF infants at 10-14 weeks [OR = 0.27 (CI 0.12-0.64)] and 18-22 weeks [OR = 0.50 (CI 0.27-0.90)]. Conclusions: The prevalence of EBF is suboptimal in our setting, with illness incidences significantly higher in non-EBF children. Appropriate intervention strategies need to be tailored to reinforce early initiation and continuation of EBF throughout the first six months of life.

Sleep Quality and Emotional State of Medical Students in Dubai.

Poor sleep quality has been reported to be common amongst medical students and healthcare professionals worldwide. Sleep disturbance has been associated with increased rates of burnout and depression. As a result, this has been negatively impacting performance and functioning. Research on this topic is limited in the United Arab Emirates (UAE). This study is aimed at exploring sleep pattern and the emotional state of medical and dental students in Dubai, UAE. This cross-sectional study was based on an electronic survey sent to 181 medical and dental students. Of the 181 invitations, 96 individuals agreed to participate and complete the rating scales. The Pittsburgh Sleep Quality Index was utilized to explore sleep duration, quality, and daytime functioning. The Positive and Negative Affect Scale was used to assess the emotional states of the participants. Overall, the findings revealed diminished sleep duration. The average duration of sleep amongst the study participants was 5 hours and 24 minutes, which is significantly below the recommended duration as per sleep guidelines. Results also showed a significant positive correlation between total sleep duration and overall sleep quality with enthusiasm during the day. Future research designed to explore factors contributing to sleep efficiency, in more depth, as well as strategies to enhance sleep quality is highly warranted.

Noninvasive Ventilation in the Management of Respiratory Failure Due to COVID-19 Infection: Experience From a Resource-Limited Setting.

OBJECTIVE: To study the role of noninvasive ventilation (NIV) in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV2) related acute respiratory failure (C-ARF). PATIENTS AND METHODS: Patients with C-ARF managed on NIV were categorized as NIV success or failure (death or intubation). Factors associated with failure were explored using regression analysis and expressed as odds ratio (OR) with 95% CI. RESULTS: Between April 1, 2020, and September 15, 2020, a total of 286 patients with a mean ± SD age of 53.1±11.6 years and Acute Physiology and Chronic Health Evaluation II score of 11.1±5.5 were initiated on NIV. Of the 182 patients (63.6%) successfully managed on NIV alone, 118 had moderate or severe acute respiratory distress syndrome. When compared with NIV success, NIV failure was associated with lower admission PaO2 to fraction of inspired oxygen ratio (P<.001) and higher respiratory rate (P<.001). On penalized logistic regression analysis, NIV failure was associated with higher Acute Physiology and Chronic Health Evaluation II score (OR, 1.12; 95% CI, 1.01 to 1.24), severe acute respiratory distress syndrome (OR, 3.99; 95% CI, 1.24 to 12.9), D-dimer level of 1000 ng/mL DDU (to convert to mg/L, divide by 1000) or greater (OR, 2.60; 95% CI, 1.16 to 5.87), need for inotropes or dialysis (OR, 12.7; 95% CI, 4.3 to 37.7), and nosocomial infections (OR, 13.6; 95% CI, 4.06 to 45.9). Overall mortality was 30.1% (86/286). In patients requiring intubation, time to intubation was longer in nonsurvivors than survivors (median, 5; interquartile range, 3-8 vs 3; interquartile range, 2-3 days; P<.001). CONCLUSION: Noninvasive ventilation can be used successfully in C-ARF. Illness severity and need for non-respiratory organ support predict NIV failure.

Breast milk contains red cell isohaemagglutinins: An observational study of 176 mothers.

BACKGROUND AND OBJECTIVES: Maternal antibodies are transferred to the child, predominantly IgG, via the transplacental route, and mostly IgA through breast milk. Cases reported by us and others have shown the transfer of red cell allo-antibodies through breast milk. This study was conducted to assess the presence of isohaemagglutinins in breast milk, the range of titres, and the correlation between breast milk and maternal plasma titres. MATERIALS AND METHODS: A total of 176 mothers were recruited in this study. Breast milk was collected after sufficient feeding was established and within 2-5 days of delivery in a sterile container without any anticoagulant. Antibody screen, identification and titres were performed on maternal plasma as well as breast milk. RESULTS: Anti-A and anti-B in breast milk corresponding to their respective maternal blood groups were found in all the samples. This study has shown titres in the breast milk of anti-A and anti-B ranging from 2 to 1024 in both saline and Coombs phases. There was no association between plasma and breast milk titres, thus making it impossible to predict which mother may potentially transfer a larger amount of these haemagglutinins. Isotypes of anti-A and anti-B were evaluated in both plasma and breast milk of 11 samples, which showed predominantly IgG in 7 (63.63%) and predominantly IgA in 4 (36.36%) samples. CONCLUSION: Our study demonstrates the presence of a wide range of titres for IgG antibodies of the ABO blood group system in breast milk. The clinical impact of this finding needs to be studied further, as it assumes great relevance in developing countries where anaemia continues to challenge young infants.

Factors associated with mortality among moderate and severe patients with COVID-19 in India: a secondary analysis of a randomised controlled trial.

OBJECTIVE: Large data on the clinical characteristics and outcome of COVID-19 in the Indian population are scarce. We analysed the factors associated with mortality in a cohort of moderately and severely ill patients with COVID-19 enrolled in a randomised trial on convalescent plasma. DESIGN: Secondary analysis of data from a Phase II, Open Label, Randomized Controlled Trial to Assess the Safety and Efficacy of Convalescent Plasma to Limit COVID-19 Associated Complications in Moderate Disease. SETTING: 39 public and private hospitals across India during the study period from 22 April to 14 July 2020. PARTICIPANTS: Of the 464 patients recruited, two were lost to follow-up, nine withdrew consent and two patients did not receive the intervention after randomisation. The cohort of 451 participants with known outcome at 28 days was analysed. PRIMARY OUTCOME MEASURE: Factors associated with all-cause mortality at 28 days after enrolment. RESULTS: The mean (SD) age was 51±12.4 years; 76.7% were males. Admission Sequential Organ Failure Assessment score was 2.4±1.1. Non-invasive ventilation, invasive ventilation and vasopressor therapy were required in 98.9%, 8.4% and 4.0%, respectively. The 28-day mortality was 14.4%. Median time from symptom onset to hospital admission was similar in survivors (4 days; IQR 3-7) and non-survivors (4 days; IQR 3-6). Patients with two or more comorbidities had 2.25 (95% CI 1.18 to 4.29, p=0.014) times risk of death. When compared with survivors, admission interleukin-6 levels were higher (p<0.001) in non-survivors and increased further on day 3. On multivariable Fine and Gray model, severity of illness (subdistribution HR 1.22, 95% CI 1.11 to 1.35, p<0.001), PaO2/FiO2 ratio <100 (3.47, 1.64-7.37, p=0.001), neutrophil lymphocyte ratio >10 (9.97, 3.65-27.13, p<0.001), D-dimer >1.0 mg/L (2.50, 1.14-5.48, p=0.022), ferritin ≥500 ng/mL (2.67, 1.44-4.96, p=0.002) and lactate dehydrogenase ≥450 IU/L (2.96, 1.60-5.45, p=0.001) were significantly associated with death. CONCLUSION: In this cohort of moderately and severely ill patients with COVID-19, severity of illness, underlying comorbidities and elevated levels of inflammatory markers were significantly associated with death. TRIAL REGISTRATION NUMBER: CTRI/2020/04/024775.

Rodenticide ingestion is an important cause of acute hepatotoxicity in Tamil Nadu, southern India.

BACKGROUND AND AIM: Though rodenticidal hepatotoxicity is reported from India, there is no systematic study to assess its magnitude. This study aimed to assess exposure to rodenticide as a risk factor for acute hepatotoxicity in Tamil Nadu, India. METHODS: We retrospectively analyzed acute hepatotoxicity caused by ingestion of hepatotoxin or potentially hepatotoxic drug overdose across 15 hospitals in 6 districts of Tamil Nadu from 1 January 2019 to 30 June 2019. Study exclusion criteria were idiosyncratic drug-induced liver injury and chronic liver diseases. RESULTS: Of the 702 patients, 685 gave history of consuming rodenticide; hepatotoxicity in the other patients resulted from paracetamol overdose (n=10) and due to other drugs (n=7); 97% patients had a suicidal intent. Of 671 patients with complete data, ratio of number of patients with hepatotoxicity due to rodenticide to paracetamol overdose was 450:6 (i.e. 75:1). The 451 rodenticidal hepatotoxicity patients (255 males, 75% were 15-34 years old) underwent conservative management (n=396), plasma exchange (n=54) and plasma exchange followed by liver transplant (n=1); 159 patients (35%) had poor outcome (131 died, 28 discharged in moribund state). Based on our observations, we estimate a case burden of 1584 rodenticidal hepatotoxicity patients (95% CI: 265-6119) with poor outcome in 554 patients in Tamil Nadu from January 2019 to June 2019. Population attributable risk for rodenticide as cause of hepatotoxicity was 22.7%. CONCLUSION: Rodenticide ingestion was an important cause of acute hepatotoxicity in Tamil Nadu. Most patients were young and one-third had poor outcome. Public health interventions are needed to address this.

The prevalence, severity, and risk factors for dry eye disease in Dubai - a cross sectional study.

BACKGROUND: The prevalence of dry eye disease is increasing globally and requires the attention of healthcare professionals as it worsens patients' quality of life. No published studies on the epidemiology of dry eyes have been found in Dubai. PURPOSE: To describe the epidemiology, prevalence, severity, and associated factors of dry eyes in Dubai, United Arab Emirates, in 2019. METHODS: This was an analytical, cross-sectional, survey-based study. An online survey was distributed by email to Mohammed Bin Rashid University students, staff, and faculty and to the staff at Mediclinic City and Parkview Hospitals in Dubai, United Arab Emirates, from April-June 2019. The survey included demographic questions and the Ocular Surface Disease Index (OSDI). RESULTS: The survey was completed by 452 participants; the majority were females (288/452; 63.7 %). The prevalence of dry eyes in Dubai was estimated to be 62.6 % (283/452), with severely dry eyes being the most prevalent (119/283; 42 %). Females, high daily screen time (> 6 h), and the use of contact lenses were found to be associated with dry eyes (P-value < 0.05, 95 % confidence interval). Age was found to be negatively correlated with prevalence of dry eyes. Exposure to smoking/shisha, history of eye injury/surgery, and nationality were not associated with dry eyes. CONCLUSIONS: This is the first cross-sectional study to investigate the prevalence of dry eyes in Dubai (62.6 %). The majority of participants had severe dry eyes symptoms. Severely dry eyes were more common among females and users of contact lenses.

Diagnostic accuracy of urinary aquaporin-1 as a biomarker for renal cell carcinoma.

INTRODUCTION: Optimal patient selection plays a vital role in management of renal tumors with the introduction of nephron-sparing approaches and active surveillance. A reliable and accurate diagnostic biomarker will be a useful adjunct to decision-making. We studied the diagnostic accuracy of urinary aquaporin-1 (uAQP-1), an upcoming urinary biomarker, for renal cell carcinoma. MATERIALS AND METHODS: In this prospective biomarker study, urine samples were obtained preoperatively from 36 patients with an imaged renal mass suggestive of RCC and 24 healthy age-matched controls, chosen from among voluntary kidney donors. uAQP-1 concentrations were estimated with a sensitive and specific enzyme-linked immunosorbent assay (ELISA) and normalized by estimation of urinary creatinine. The Mann-Whitney U-test was used to compare differences between any two groups. A receiver operator characteristic (ROC) curve was plotted to analyze the diagnostic accuracy of uAQP-1 for RCC. RESULTS: The median uAQP-1 concentration among the cases and controls was 8.78 ng/mg creatinine (interquartile range [IQR]: 5.56-12.67) and 9.52 ng/mg creatinine (IQR: 5.55-12.45), respectively. There was no significant difference in uAQP-1 concentrations between the two groups. ROC analysis showed that, for a cutoff value of 8 ng/mg creatinine, the sensitivity and specificity of uAQP-1 as a diagnostic test were 47.2% and 66.7%, respectively, and area under the curve was 0.52 (95% confidence interval: 0.42-0.62). CONCLUSIONS: uAQP-1 concentrations did not discriminate between healthy individuals and patients with RCC. The results of this study suggest that uAQP-1 may not be a suitable diagnostic biomarker for RCC in the study population.

Defining IL-6 levels in healthy individuals: A meta-analysis.

BACKGROUND: Interleukin-6 (IL-6) is produced by and impacts different cell types in human. IL-6 is associated with different diseases and viral infections, including COVID-19. To our knowledge, no normal values were reported for IL-6 in the blood of healthy individuals. We have reviewed and performed a meta-analysis on a total of 140 studies, including 12,421 values for IL-6 in the blood of healthy adult donors. Among these studies, 83 did not report a mean value and the standard deviation. Therefore, for the statistical analysis, we used the values reported in 57 studies, which included 3166 values for IL-6. RESULTS: The reported values for IL-6 in the blood of healthy donors varied between 0 and 43.5 pg/ml. The pooled estimate of IL-6 was 5.186 pg/ml (95% confidence interval [CI]: 4.631, 5.740). As the age increased by 1 year, IL-6 values increased by 0.05 pg/ml (95% CI: 0.02, 0.09; p < .01). Though the heterogenicity, as determined by I2 statistics, was high in our study, the differences in IL-6 values are still at the level of a few pg/ml, which might be related to the differences in the conditions that influence IL-6 production in the healthy population. CONCLUSIONS: This is the first meta-analysis reporting the levels of IL-6 in the blood of healthy donors based on a large number of studies and donors. Therefore the 95% CI values determined in our study could well serve as a reference range for quick decision-making in clinical interventions, particularly those aiming to inhibit IL-6, especially urgent interventions, for example, COVID-19.

The impact of demonetisation on the utilisation of hospital services, patient outcomes and finances: a multicentre observational study from India.

BACKGROUND: This study assessed trends in healthcare utilisation in relation to the implementation of an economic policy in India wherein 500 and 1000 rupee notes were demonetised. METHODS: In this ambidirectional observational study of private not-for-profit hospitals, data on hospital outpatient and inpatient numbers, surgeries, emergency department (ED) visits, obstetric admissions and mortality were obtained for pre-demonetisation (September/October 2016), early (November/December 2016) and late demonetisation (January/February 2017), and post-demonetisation periods (March/April 2017) and compared with the control period (2015-2016) from 11 centres (three tertiary hospitals; eight secondary). A Bayesian regression analysis was performed to adjust for seasonal (winter) effect. Monthly financial data, including the proportion of cash versus non-cash transactions, were collected. FINDINGS: Overall, at the pooled all-hospital level, Bayesian analysis showed non-significant increase in outpatients (535.4, 95% CI -7097 to 8116) and decrease in deaths (-6.3 per 1000 inpatients, 95% CI -15.45 to 2.75) and a significant decrease in inpatients (-145.6, 95% CI -286.4 to -10.63) during demonetisation. Analysis at the level of secondary and tertiary hospitals showed a variable effect. For individual hospitals, after adjusting for the seasonal effect, some hospitals observed a significant reduction in outpatient (n=2) and inpatient (n=3) numbers, ED visits (n=4) and mortality (n=2) during demonetisation, while others reported significantly increased outpatient numbers (n=3) and ED visits (n=2). Deliveries remained unchanged during demonetisation in the hospitals that provided the service. There was no significant reduction in hospital incomes during demonetisation. In tertiary hospitals, there was a significant increase in non-cash component of transactions from 35% to 60% (p=0.02) that persisted beyond the demonetisation period. CONCLUSIONS: The effect of demonetisation on healthcare utilisation was variable. Some hospitals witnessed a significant reduction in utilisation in some areas, while others reported increased utilisation. There was an increase in non-cash transactions that persisted beyond the period of demonetisation.

Feasibility of computer-generated telephonic message-based follow-up system among healthcare workers with diabetes: a randomized controlled trial.

INTRODUCTION: To assess the feasibility of computer-generated educational messaging system in healthcare workers of a tertiary care hospital. The secondary objectives were glycemic control, patient satisfaction and adherence to lifestyle modifications. RESEARCH DESIGN AND METHODS: Single-center parallel-group open-labeled randomized controlled trial with computer generated block randomization. SETTING: Healthcare workers with diabetes working in Christian Medical College Vellore, Tamil Nadu. PARTICIPANTS: 431 assessed, 341 met the selection criteria, 320 participants were randomized and 161 were taken into intervention arm and 159 in the control arm. INTERVENTION: Computer-generated short message service (SMS) based on transtheoretical model of behavioral change, 2 messages per week for 3 months, along with standard of care diabetic care. Messages had educational material regarding healthy eating habits and exercise and these messages were sent twice weekly.
