Effect of pulmonary rehabilitation in patients with post-tuberculosis sequelae with functional limitation

BACKGROUND

Pulmonary rehabilitation improves dyspnea, functional limitation and quality of life in patients with chronic respiratory disease especially Chronic obstructive pulmonary disease (COPD). Whether Pulmonary rehabilitation (PR) will have similar effect in patients with post-tuberculosis sequelae or not and whether the two morphological variants will respond similarly or not was the purpose of our study.

METHODS

Adult patients fulfilling the inclusion criteria of a diagnosis of post-tuberculosis sequelae with functional limitation (modified medical research council [mMRC] grade 1 or more) were recruited over a period of two years. A baseline health assessment in the different domains of health was done at the beginning and repeated just after the completion of the rehabilitation program at 6 weeks.

RESULTS

26 patients completed the PR protocol of our study. Dyspnea improved from an mMRC grade of 1.5 to 0.7 post-PR (p < 0.001). 6MWD increased by 34 meters from a baseline value of 408.6 meters to 442.7 meters post-PR. (p-value 0.3) St. George's Respiratory Questionnaire (SGRQ) symptom score decreased by 13 points, SGRQ activity score decreased by 18 points, SGRQ impact score decreased by 18 and SGRQ total score decreased by 17 points with p-values of 0.037, 0.002, 0.004 and 0.002 for SGRQ symptom score, SGRQ activity score, SGRQ impact score, SGRQ total score respectively. Depression Anxiety Stress Scale (DASS) Stress score decreased by 6.7, DASS Anxiety score decreased by 6.6, and DASS Depression score decreased by 5.5 points. Intergroup comparison revealed both bronchiectasis predominant group and fibrosis predominant group responded similarly to PR.

CONCLUSION

PR improved parameters assessing dyspnea, quality of life and mental health indices significantly. Improvement in functional capacity was not statically significant. Both the morphological variants responded similarly to the PR.

Sex-specific differences in presenting symptoms of obstructive sleep apnea

OBJECTIVES

Scant data from India are available on the gender differences in presenting features of Obstructive Sleep Apnea (OSA) in India. This study aims to compare male and female patients with OSA for general characteristics and presenting symptoms.

METHODOLOGY

Retrospective study was done in OSA patients diagnosed in our sleep lab. History, biochemical reports, and polysomnography variables were retrieved from the sleep registry and were compared between males and females.

RESULTS

Out of 514 patients of OSA (367 males; 147 females). Females were older (55.97 ± 9.73 v/s 50.2 + 12.70 years, P<0.001) and more obese (BMI 35.26 ± 7.17 v/s 29.58 ± 5.49 Kg/m2; P<0.001). Waist and hip circumference were significantly higher in the female patients (P = 0.009 and <0.001 respectively). Morning headache, nocturia, fatigability (P < 0.001), and depression (P = 0.005) was more common in females (P = 0.036). Hypersomnia was more commonly seen in males (P < 0.001). Mean diastolic blood pressure was significantly higher in males, although no difference was seen in Systolic BP. Females had higher mean Fasting Blood glucose (FBS) (P = 0.02). Apnea hypopnea index was significantly higher in females {P = 0.01}.

CONCLUSION

Women with OSA are more obese, elderly, and with higher fasting blood glucose than males at the time of diagnosis. Females have a higher prevalence of symptoms like fatigability, depression, nocturia and early morning headache and had more severe AHI than males.

Risk Factors for Unfavorable Glycemic Control Trajectory in Type-2 Diabetes Mellitus: A Community-based Longitudinal Study in Urbanslums of Central India

BACKGROUND

Diabetes mellitus (DM) is a chronic disease, which requires optimal glycemic control to prevent its ensuing vascular complications. Pathway to optimal glycemic control in T2DM has a complex socio-behavioral construct, especially in vulnerable populations, like slum dwellers, who have reduced health-care access and lower prioritization of health needs.

OBJECTIVE

The study aimed to map trajectories of glycemic control amongst individuals with T2DM living in urban slums and identify key determinants associated with unfavourable glycaemic trajectory.

METHODS

This study was a community-based longitudinal study conducted in an urban slum of Bhopal in Central India. Adult patients diagnosed with T2DM and on treatment for more than one year were included. All 326 eligible participants underwent a baseline interview, which captured sociodemographic, personal behavior, medication adherence, morbidity profile, treatment modality, anthropometric and biochemical measurements (HbA1c). Another 6-month follow-up interview was conducted to record anthropometric measurements, HbA1c and treatment modality. Four mixed effect logistic regression models (through theory-driven variable selections) were created with glycemic status as dependent variable and usage of insulin was considered as random effect.

RESULTS

A total of 231 (70.9%) individuals had unfavorable glycemic control trajectory (UGCT), and only 95 (29.1%) had a favorable trajectory. Individuals with UGCT were more likely to be women, with lower educational status, non-vegetarian food preference, consumed tobacco, had poor drug adherence, and were on insulin. The most parsimonious model identified female gender (2.44,1.33-4.37), tobacco use (3.80,1.92 to 7.54), and non-vegetarian food preference (2.29,1.27 to 4.13) to be associated with UGCT. Individuals with good medication adherence (0.35,0.13 to 0.95) and higher education status (0.37,0.16 to 0.86) were found to be protective in nature.

CONCLUSION

Unfavorable glycemic control trajectory seems to be an inescapable consequence in vulnerable settings. The identified predictors through this longitudinal study may offer a cue for recognizing a rational response at societal level and adopting strategy formulation thereof.

The analgesic efficacy of ultrasound-guided erector spinae plane block versus ultrasound-guided caudal epidural block for abdominal surgery in pediatric patients - A patient and assessor-blind, randomized controlled study

Background

Literature on the efficacy and safety of erector spinae plane block (ESPB) in pediatric patients is limited. Hence, we aimed to compare ESPB versus caudal epidural block (CEB) in children undergoing abdominal surgery.

Methods

In this patient and assessor-blind study, fifty-two ASA I-II patients, between 1 to 9 years of age, were randomized into groups of 26 each. ESPB group received unilateral or bilateral ultrasound (USG)-guided ESPB with 0.5 ml/kg of 0.25% bupivacaine per side. CEB group received USG-guided CEB with 1 ml/kg of 0.25% bupivacaine. The primary objective was to estimate the proportion of patients requiring postoperative rescue analgesia. The secondary objectives were to assess postoperative Face, Legs, Activity, Cry and Consolability (FLACC) scale scores, duration of analgesia, and consumption of rescue analgesic drugs.

Results

More patients in the ESPB group (88.4%), compared to the CEB group (42.3%), required rescue analgesics (P value <0.001). FLACC scores in the ESPB group, though satisfactory, were inferior, to the CEB group. The duration of postoperative analgesia was shorter in the ESPB group by 9.54 h (95% CI: 4.51 to 14.57 h, P value <0.001). The median (IQR) consumption of rescue paracetamol was significantly higher in the ESPB group (20 mg/kg (10,20) compared to the CEB group (0.0 mg/kg (0.0,10) P value <0.001)). No adverse effects were reported.

Conclusion

In children undergoing abdominal surgery, both ESPB and CEB were safe and efficacious. CEB provided a longer duration and better quality of analgesia. ESPB may be considered when CEB is contraindicated or difficult.

Translation of Parkinson's Disease Sleep Scale-2 (PDSS-2) in Hindi (H-PDSS-2) and its Validation for Assessment of Sleep Disturbances among Indian Parkinson's Disease Patients

Background and Objective

Parkinson's disease sleep scale-2 (PDSS-2) is a reliable sleep assessment tool which has been validated in several languages. As sleep problems have a great impact on the quality of life of Parkinson's disease patients, we aimed to translate and validate PDSS-2 in Hindi for its wider use among Hindi-speaking Indian patients. Our study objective was to translate PDSS-2 in Hindi (H-PDSS-2) and to assess the psychometric properties of H-PDSS-2 questionnaire for its use in Hindi-speaking Indian PD patients. Secondly, we aimed to compare the results with those of the other language PDSS-2 validation studies.

Material and Methods

This study was done in two phases, enrolling 16 patients and 16 controls in the first/translation phase for assessment of internal consistency and discriminative power of PDSS-2. The test-retest reliability was determined in the second phase on 35 Parkinson's disease patients who were followed-up at an interval of 7-10 days.

Results

No difficulties were faced by the patients and controls in the first phase, and internal consistency of the scale was good (Cronbach's alpha = 0.804). There was no significant difference in total H-PDSS-2 score at baseline 16.86 ± 10.59 and on retest 16.40 ± 9.54, suggesting good reliability. Intraclass correlation coefficients ranged from 0.710 to 0.901, and precision was 2.82 over the period of 7-10 days. Subdomains of H-PDSS-2 had moderate/high internal validity, and they showed significant correlation with Unified PD Rating Scale (UPDRS) and HY disease scale.

Conclusion

H-PDSS-2 is equivalent to the original PDSS-2 for tested psychometric attributes. Its use among Indian Parkinson's disease patients will help in the comprehensive assessment of sleep problems among PD patients.

Status of Hypertension Control in Urban Slums of Central India: A community Health Worker-Based Two-Year Follow-Up

Background

Hypertension (HTN) is a leading cause of cardiovascular diseases and its control is poor. There is heterogeneity in levels of blood pressure control among various population subgroups. The present study was conducted within the framework of the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases, and Stroke (NPCDCS) in India. It aims to estimate the proportion of optimal blood pressure control and identify factors associated with uncontrolled HTN consequent to initial screening.

Materials and Methods

We assembled a cohort of individuals with HTN confirmed in a baseline screening in sixteen urban slum clusters of Bhopal (2017-2018). Sixteen accredited social health activists were trained from within these slums. Individuals with HTN were linked to primary care providers and followed up for the next two years. Obtaining optimal blood pressure control (defined as SBP <140 and DBP <90 mm of Hg) was a key outcome.

Results

Of a total of 6174 individuals, 1571 (25.4%) had HTN, of which 813 were previously known and 758 were newly detected during the baseline survey. Two-year follow-up was completed for 1177 (74.9%). Blood pressure was optimally controlled in 301 (26%) at baseline and in 442 (38%) individuals at two years (an absolute increase of 12%; 95% CI 10.2-13.9). Older age, physical inactivity, higher body mass index, and newly diagnosed HTN were significantly associated with uncontrolled blood pressure.

Conclusion

We found about six of every ten individuals with HTN were on treatment, and about four were optimally controlled. These findings provide a benchmark for NPCDCS, in terms of achievable goals within short periods of follow-up.

Obstructive sleep apnea and ambulatory blood pressure abnormalities in children with chronic kidney disease

BACKGROUND

Obstructive sleep apnea (OSA) and hypertension are common complications in children with chronic kidney disease (CKD). Progression of CKD can aggravate OSA and hypertension whereas worsening sleep apnea can make hypertension difficult to treat in CKD patients. We, therefore, conducted a prospective study to evaluate the association between OSA and hypertension in pediatric patients with CKD.

METHOD

In this prospective observational study consecutive children with CKD stage 3-5 (nondialysis dependent) underwent overnight polysomnography and 24-h ambulatory blood pressure monitoring (ABPM). The detailed clinical features and investigations were recorded in a prestructured performa.

RESULTS

Twenty-two children completed overnight polysomnography and 24-h ABPM was performed within 48 h of performing polysomnography. The median (IQR) age of the study population was 11 (8.5-15.5) years, with an age range of 5-18 years. Moderate-severe OSA defined as apnea-hypopnea index (AHI ≥5) was seen in 14 (63.6%) children, periodic limb movement syndrome in 20 (91%) and poor sleep efficacy in 9 (40.9%) children. Ambulatory blood pressure was abnormal in 15 (68.2%) children with CKD. Of them, 4 (18.2%) had ambulatory hypertension, 9 (40.9%) had severe ambulatory hypertension and 2 (9.1%) had masked hypertension. A statistically significant correlation of sleep efficiency with nighttime DBP SD score/Z score (SDS/Z) (r = -0.47; P = 0.02); estimated glomerular filtration rate with SBP loads (r = -0.61; P < 0.012); DBP loads (r = -0.63; P < ) and BMI with SBP load (r = 0.46; P = 0.012) was found.

CONCLUSION

Our preliminary findings suggest that ambulatory blood pressure abnormalities, OSA, periodic limb movement syndrome and poor sleep efficiency are highly prevalent in children with CKD stages 3-5.

Predictors of Mortality among Patients Hospitalized with COVID-19 during the First Wave in India: A Multisite Case-Control Study

Severe acute respiratory syndrome coronavirus 2 disease (COVID-19) has caused more than 6 million deaths globally. Understanding predictors of mortality will help in prioritizing patient care and preventive approaches. This was a multicentric, unmatched, hospital-based case-control study conducted in nine teaching hospitals in India. Cases were microbiologically confirmed COVID-19 patients who died in the hospital during the period of study and controls were microbiologically confirmed COVID-19 patients who were discharged from the same hospital after recovery. Cases were recruited sequentially from March 2020 until December-March 2021. All information regarding cases and controls was extracted retrospectively from the medical records of patients by trained physicians. Univariable and multivariable logistic regression was done to assess the association between various predictor variables and deaths due to COVID-19. A total of 2,431 patients (1,137 cases and 1,294 controls) were included in the study. The mean age of patients was 52.8 years (SD: 16.5 years), and 32.1% were females. Breathlessness was the most common symptom at the time of admission (53.2%). Increasing age (adjusted odds ratio [aOR]: 46-59 years, 3.4 [95% CI: 1.5-7.7]; 60-74 years, 4.1 [95% CI: 1.7-9.5]; and ≥ 75 years, 11.0 [95% CI: 4.0-30.6]); preexisting diabetes mellitus (aOR: 1.9 [95% CI: 1.2-2.9]); malignancy (aOR: 3.1 [95% CI: 1.3-7.8]); pulmonary tuberculosis (aOR: 3.3 [95% CI: 1.2-8.8]); breathlessness at the time of admission (aOR: 2.2 [95% CI: 1.4-3.5]); high quick Sequential Organ Failure Assessment score at the time of admission (aOR: 5.6 [95% CI: 2.7-11.4]); and oxygen saturation < 94% at the time of admission (aOR: 2.5 [95% CI: 1.6-3.9]) were associated with mortality due to COVID-19. These results can be used to prioritize patients who are at increased risk of death and to rationalize therapy to reduce mortality due to COVID-19.

Effectiveness of Semmes Weinstein 10 gm monofilament in diabetic peripheral neuropathy taking nerve conduction and autonomic function study as reference tests

Context

Diabetic peripheral neuropathy (DPN) if detected early can reduce the burden on the health system and prevent the development of diabetic foot ulcers and amputation.

Aim

To study the effectiveness of Semmes Weinstein 10 gm monofilament in detecting DPN taking nerve conduction studies (NCS) and autonomic function testing (AFT) as reference tests.

Settings and Design

Observational and comparative cross-sectional study conducted in the Physiology department AIIMS, Bhopal in collaboration with the Medicine department of the institute.

Methods and Material

A total of 72 diagnosed type-2 diabetes mellitus patients were examined using Semmes Weinstein 10 gm monofilament, DPN was confirmed using NCS (Nihon Kohden Neuropack XI machine) and autonomic neuropathy was confirmed using AFT (Ewing's battery and Power lab) with heart rate variability (HRV). Diagnostic value of Semmes Weinstein 10 gm monofilament taking NCS and AFT as reference test was calculated.

Statistical Analysis Used

Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) were calculated using the standard formula.

Results

Sensitivity, specificity, PPV, and NPV using monofilament are 69.23%, 20%, 69.23% and 20% respectively taking NCS as reference test and 70.59%, 0, 92.30%, and 0 respectively taking AFT as reference test.

Conclusions

Semmes Weinstein 10 gm monofilament is not the ideal screening test for the diagnosis of DPN. Sole clinical use of monofilament should be discouraged.

Barriers in reaching new-borns and infants through home visits: A qualitative study using nexus planning framework

Background

Home visitation has emerged as an effective model to provide high-quality care during pregnancy, childbirth, and post-natal period and improve the health outcomes of mother- new born dyad. This 360⁰ assessment documented the constraints faced by the community health workers (known as the Accredited Social Health Activists, ASHAs) to accomplish home visitation and deliver quality services in a poor-performing district and co-created the strategies to overcome these using a nexus planning approach.

Methods

The study was conducted in the Raisen district of Madhya Pradesh, India. The grounded theory approach was applied for data collection and analysis using in-depth interviews, and focus group discussions with stakeholders representing from health system (including the ASHAs) and the community (rural population). A key group of diverse stakeholders were convened to utilize the nexus planning five domain framework (social-cultural, educational, organizational, economic, and physical) to prioritize the challenges and co-create solutions for improving the home visitation program performance and quality. The nexus framework provides a systemic lens for evaluating the success of the ASHAs home visitation program.

Results

The societal (caste and economic discrimination), and personal (domestic responsibilities and cultural constraints of working in the village milieu) issues emerged as the key constraints for completing home visits. The programmatic gaps in imparting technical knowledge and skills, mentoring system, communication abilities, and unsatisfactory remuneration system were the other barriers to the credibility of the services. The nexus planning framework emphasized that each of the above factors/domains is intertwined and affects or depends on each other for home-based maternal and newborn care services delivered with quality through the ASHAs.

Conclusion

The home visitation program services, quality and impact can be enhanced by addressing the social-cultural, organizational, educational, economic, and physical nexus domains with concurrent efforts for skill and confidence enhancement of the ASHAs and their credibility.

Changing Critical Care Patterns and Associated Outcomes in Mechanically Ventilated Severe COVID-19 Patients in Different Time Periods: An Explanatory Study from Central India

Background

The outcomes in critical illness depend on disease severity, practice protocols, workload, and access to care. This study investigates the factors affecting outcomes in mechanically ventilated coronavirus disease-2019 acute respiratory distress syndrome (COVID-19 ARDS) patients admitted in a tertiary teaching hospital intensive care unit (ICU) in Central India with reference to different time periods in pandemic. This is one of the largest series of mechanically ventilated COVID-19 ARDS patients, globally.

Methods

This retrospective cohort study classified the entire data into four time periods (Period 1: April 2020 to June 2020; Period 2: July 2020 to September 2020; Period 3: October 2020 to December 2020; and Period 4: January 2021 to April 2021). We performed a multivariable-adjusted analysis to evaluate predictors of mortality, adjusted for baseline-severity, sequential organ failure assessment (SOFA score) and time period. We applied mixed-effect binomial logistic regression to model fixed-effect variables with incremental complexity.

Results

Among the 56 survivors (19.4%) out of 288 mechanically ventilated patients, there was an up-gradient of survival proportion (0, 18.2, 17.4, and 28.6%) in four time periods. Symptom–intubation interval (OR 1.16; 95% CI 1.03–1.31) and driving pressures (DPs) (OR 1.17; 95% CI 1.07–1.28) were significant predictors of mortality in the model having minimal AIC and BIC values. Patients aged above 60 years also had a larger effect, but statistically insignificant effect favoring mortality (OR 1.99; 95% CI 0.92–4.27). The most complex but less parsimonious model (with higher AIC/BIC) indicated the protective odds of high steroid on mortality (OR 0.59; 95% CI 0.59–0.82).

Conclusion

The outcomes in mechanically ventilated COVID-19 ARDS patients are heterogeneous across time windows and may be affected by the complex interaction of baseline risk and critical care parameters.

Clinico–Epidemio-Microbiological Exploratory Review Among COVID-19 Patients with Secondary Infection in Central India

Purpose

Secondary infections (SI) in COVID-19 have been documented from 3.6% to 72% in various studies with mortality ranging from 8.1% to 57.6%. There is a gap in knowledge for clinico–epidemio-microbilogical association among COVID-19 patients with concomitant SI.

Patients and Methods

This is a retrospective chart review, in central India. The study was undertaken for hospitalized adult patients during 1st June 2020 to 30th November 2020, with laboratory proven COVID-19 infection and secondary infection.

Results

Out of the total 2338 number of patients, only 265 (11.3%) patients were investigated for microbiological identification of SI. Male gender was predominant (76.8%) and the mean age was 53.7 ± 17.8 years. Only 3.5% (82/2338) of patients were having microbiologically confirmed (bacterial or fungal) SI. The overall mortality was 50.9% (54/82) with a differential mortality of 88.8% (48/54) in high-priority areas and 21.4% (6/28) in low-priority areas. Blood was the most commonly investigated sample (56%) followed by urine (20.7%) and respiratory secretion (15.8%). A. baumanii complex (20/82, 24.3%) was the most common bacteria isolated followed by K. pneumonia (12/82, 14.6%) and E. coli (11/82, 13.4%). Candida spp. (20/82, 24.3%) was the most common fungal pathogen isolated. Sixty percent (12/20) of Acinetobacter spp. were carbapenam-resistant and 70.3% of Enterobacterales were carbapenam-resistant. Fluconazole resistant Candida spp. was isolated only in 10% (2/20) of cases. Diabetes was the most common co-morbidity 54.8% (45/82) followed by hypertension (41.4%) and chronic heart disease (13.4%). The negative predictors of secondary infections are urinary catheterization, placement of central line and mechanical ventilation (invasive and non-invasive).

Conclusion

There is an urgent need of better anti-microbial stewardship practices in India (institutional and extra institutional) for curtailment of secondary infection rates particularly among COVID-19 patients.

On Admission, Microcirculation Abnormality is an Independent Predictor of Sepsis and Sepsis-related Mortality: A Hospital-based Study

Background

Microcirculatory derangement is the primary cause of organ dysfunction in patients with sepsis. Assessment of the microcirculation is usually done by means of indirect parameters (SvO₂ transcutaneous PO₂ serum lactate.) The aim of our study is to understand microcirculatory abnormalities in patients with sepsis by directly visualizing the tiny vessels using hand-held video microscopes (HVMs) and determining the role of this modality in the prediction of sepsis-related mortality.

Methods

A longitudinal prospective hospital-based study was carried out in medical ward and ICU of a tertiary care hospital. Patients admitted with the presumed infectious disease were included. Evaluation of sublingual microcirculation was done in these patients from Day 1 to Day 5 Clinical and laboratory variables and microcirculation variables were compared between patients with or without sepsis and between survivors and non-survivors of sepsis. Chi-square test for categorical and Student's t-test or Wilcoxon rank-sum test for continuous variables were applied. Univariate and multivariate regression analyses were performed using the Cox-proportional hazard model.

Results and discussion

On admission, microcirculation assessment measure, PPV (small), was significantly reduced in those with sepsis, as compared to those without sepsis. Multivariable models indicate the inverse relationship of PPV small with mortality.

Comparative analysis of the diagnostic performance of five commercial COVID-19 qRT PCR kits used in India

To meet the unprecedented requirement of diagnostic testing for SARS-CoV-2, a large number of diagnostic kits were authorized by concerned authorities for diagnostic use within a short period of time during the initial phases of the ongoing pandemic. We undertook this study to evaluate the inter-test agreement and other key operational features of 5 such commercial kits that have been extensively used in India for routine diagnostic testing for COVID-19. The five commercial kits were evaluated, using a panel of positive and negative respiratory samples, considering the kit provided by National Institute of Virology, Indian Council of Medical Research (2019-nCoV Kit) as the reference. The positive panel comprised of individuals who fulfilled the 3 criteria of being clinically symptomatic, having history of contact with diagnosed cases and testing positive in the reference kit. The negative panel included both healthy and disease controls, the latter being drawn from individuals diagnosed with other respiratory viral infections. The same protocol of sample collection, same RNA extraction kit and same RT-PCR instrument were used for all the kits. Clinical samples were collected from a panel of 92 cases and 60 control patients, who fulfilled our inclusion criteria. The control group included equal number of healthy individuals and patients infected with other respiratory viruses (n = 30, in each group). We observed varying sensitivity and specificity among the evaluated kits, with LabGun COVID-19 RT-PCR kit showing the highest sensitivity and specificity (94% and 100% respectively), followed by TaqPath COVID-19 Combo and Allplex 2019-nCoV assays. The extent of inter-test agreement was not associated with viral loads of the samples. Poor correlation was observed between Ct values of the same genes amplified using different kits. Our findings reveal the presence of wide heterogeneity and sub-optimal inter-test agreement in the diagnostic performance of the evaluated kits and hint at the need of adopting stringent standards for fulfilling the quality assurance requirements of the COVID-19 diagnostic process.

Immature Platelet Fraction: Its Clinical Utility in Thrombocytopenia Patients

Objectives Etiology of thrombocytopenia is multifactorial and its pathogenesis should be distinguished for appropriate management. Newly formed immature platelets are called reticulated platelets (RPs) and can be estimated in peripheral blood using automated hematology analyzers, which express them as immature platelet fraction (IPF). In the present study we intend to assess and establish the clinical utility of IPF in differentiating the two major causes of thrombocytopenia-decreased production and increased destruction of platelets-along with determining its significance in monitoring patients with thrombocytopenia. Materials and Methods Sixty-one cases of thrombocytopenia and 101 healthy controls with normal platelet count were included in the study. IPF and all the other usual blood cell parameters were measured using a fully automated hematology analyzer. Based on the pathogenesis of thrombocytopenia, the cases were divided into groups and the difference in IPF value between the groups was evaluated. Results The reference range of IPF among healthy controls was estimated to be 0.7 to 5.7%. The mean IPF was significantly higher in patients with increased peripheral destruction of platelets (13.4%) as compared to patients with decreased production of platelets (4.6%). The optimal cutoff value of IPF for differentiating patients with increased peripheral destruction of platelets from patients with decreased production of platelets was 5.95% with a sensitivity of 88% and specificity of 75.9%. Conclusion Measurement of IPF is useful for detecting evidence of increased platelet production and helps in the initial evaluation of thrombocytopenia patients. It is a novel diagnostic method which can be used to differentiate patients with thrombocytopenia due to increased destruction of platelets from patients with thrombocytopenia due to bone marrow failure/suppression.

Linkage to primary-care public health facilities for cardiovascular disease prevention: a community-based cohort study from urban slums in India

OBJECTIVES

Hypertension and diabetes mellitus are important risk factors for cardiovascular diseases (CVDs). Once identified with these conditions, individuals need to be linked to primary healthcare system for initiation of lifestyle modifications, pharmacotherapy and maintenance of therapies to achieve optimal blood pressure and glycaemic control. In the current study, we evaluated predictors and barriers for non-linkage to primary-care public health facilities for CVD risk reduction.

METHODS

We conducted a community-based longitudinal study in 16 urban slum clusters in central India. Community health workers (CHWs) in each urban slum cluster screened all adults, aged 30 years or more for hypertension and diabetes, and those positively screened were sought to be linked to urban primary health centres (UPHCs). We performed univariate and multivariate analysis to identify independent predictors for non-linkage to primary-care providers. We conducted in-depth assessment in 10% of all positively screened, to identify key barriers that potentially prevented linkages to primary-care facilities.

RESULTS

Of 6174 individuals screened, 1451 (23.5%; 95% CI 22.5 to 24.6) were identified as high risk and required linkage to primary-care facilities. Out of these, 544 (37.5%) were linked to public primary-care facilities and 259 (17.8%) to private providers. Of the remaining, 506 (34.9%) did not get linked to any provider and 142 (9.8%) defaulted after initial linkages (treatment interrupters). On multivariate analysis, as compared with those linked to public primary-care facilities, those who were not linked had age less than 45 years (OR 2.2 (95% CI 1.3 to 3.5)), were in lowest wealth quintile (OR 1.8 (95% CI 1.1 to 2.9), resided beyond a kilometre from UPHC (OR 1.7 (95% CI 1.2 to 2.4) and were engaged late by CHWs (OR 2.6 (95% CI 1.8 to 3.7)). Despite having comparable knowledge level, denial about their risk status and lack of family support were key barriers in this group.

CONCLUSIONS

This study demonstrates feasibility of CHW-based strategy in promoting linkages to primary-care facilities.

Medication adherence, recall periods and factors affecting it: A community-based assessment on patients with chronic diseases in urban slums

OBJECTIVE

To evaluate medication adherence, the effect of recall periods on self-reported adherence and factors influencing medication adherence among patients of chronic diseases, such as hypertension and diabetes, particularly in the community.

METHODS

A cross-sectional cohort study was conducted among individuals with hypertension and/or diabetes coming as outpatients in community camps organised in a cluster of urban slums. Responses towards questions regarding self-reported quantitative and qualitative adherence for one week and one month along with information on pill burden, socio-demographic and other factors were recorded using a mobile application.

RESULTS

Among 379 participants living in urban slum communities, who were prescribed anti-hypertensive or oral anti-diabetic medications previously, mean medication adherence over previous one week was 67.99% (standard deviation (SD) ± 38.32) and 6.87 (SD ± 3.62) on a ten-point numeric scale. The medication adherence for one month showed a strong significantly positive correlation with that of 1 week for both percentage-based (r = +0.910, 95% CI = 0.864 to 0.950, P < .0001) and Likert (ρ = +0.836, 95% CI = 0.803 to 0.863, P < .0001) scales. Age (r = 0.219, 95% CI = 0.120 to 0.313, P = .043) and pill burden (r = -0.231, 95% CI = -0.145 to -0.322, P < .0001) were found to significantly affect medication adherence. The odds of random blood sugar reduction were found to be significant (OR 1.98, 95% CI = 1.30 to 3.00, P = .001) with adequate adherence. A linear regression equation was developed to predict medication adherence percentage for a patient which was found to have 61.8% predictive power using multilayer perceptron modelling.

CONCLUSION

Overall, medication adherence was sub-optimal. Adherence assessments can be reliably performed using either one week or one month recall periods. With further refinement and validation, the regression equation could prove to be a useful tool for physicians.

Heterogeneous patterns of COVID-19 transmission in an Urban set up - sero-epidemiological survey data from Ujjain, Madhya Pradesh (a central Indian city)

In the wake of rising number of SARS-CoV-2 cases, the Government of India had placed mass-quarantine measures, termed as "lockdown" measures from end-March 2020. The subsequent phase-wise relaxation from July 2020 led to a surge in the number of cases. This necessitated an understanding of the true burden of SARS-CoV-2 in the community. Consequently, a sero-epidemiological survey was carried out in the central Indian city of Ujjain, Madhya Pradesh. This article details the processes of data acquisition, compilation, handling, and information derivation from the survey. Information on socio-demographic and serological variables were collected from 4,883 participants using a multi-stage stratified random sampling method. Appropriate weightage was calculated for each participant as sampling fraction derived from Primary Sampling Unit (PSU), Secondary Sampling Unit (SSU) and Tertiary Sampling Unit (TSU). The weightage was then applied to the data to adjust the findings at population level. The comprehensive and robust methodology employed here may act as a model for similar future endeavours. At the same time, the dataset can also be relevant for researchers in fields such as data science, epidemiology, virology and earth modelling.

Metabolic syndrome in non-obese patients with OSA: learning points of a cross-sectional study from a tertiary care hospital in Central India

STUDY OBJECTIVES

Obesity is often considered mandatory for the diagnosis of Metabolic Syndrome (MS). Data on the prevalence of MS in non-obese patients with Obstructive Sleep Apnea (OSA) is scarce. This study was aimed to determine the prevalence of MS in non-obese patients with OSA.

METHODOLOGY

All consecutively diagnosed patients with OSA between October 2018 and November 2019 were screened for metabolic syndrome. Patients with OSA and BMI < 25 kg/m² (NOOSA) vs BMI > 25 kg/m² (obese OSA) were compared. Lean waist NOOSA was defined as BMI < 25 kg/m² and WC < 80 cm (32 in.) for women or < 90 cm (36 in.) for men.

RESULTS

During the study period, 502 patients were diagnosed with OSA. MS was observed in 35% of patients with NOOSA compared to obese patients with OSA (79%). In the NOOSA group, hypertension, impaired fasting glucose, diabetes mellitus and dyslipidemia were observed in 65, 48, 14 and 61% respectively and all of these parameters were significantly more common in the obese group (p < 0.001). Parameters of OSA severity (apnea-hypopnea index or AHI, time spent below 90% saturated or T90, and nadir oxygen) were significantly more severe in the obese group with OSA. Approximately 83% of patients in the NOOSA group had at least two metabolic risk factors, compared to the obese OSA group, in which 95% had two or more metabolic risk factors. Sixty-four percent of patients with NOOSA with lean waist had at least two metabolic risk factors. At BMI cut-offs of < 25, < 27 and < 30 kg/m2; 35, 46 and 57% of patients with OSA respectively had metabolic syndrome.

CONCLUSION

Metabolic syndrome was observed in approximately one in three patients with OSA and BMI < 25 kg/m². Approximately two of every three lean waist non-obese patients with OSA had at least two markers of metabolic syndrome. The role of OSA in the development of metabolic syndrome in non-obese individuals needs further exploration.

Baseline risk factor prevalence among adolescents aged 15-17 years old: findings from National Non-communicable Disease Monitoring Survey (NNMS) of India

OBJECTIVE

To generate national estimates of key non-communicable disease (NCD) risk factors for adolescents (15-17 years) identified in the National NCD Monitoring Framework and, study the knowledge, attitudes and practices towards NCD risk behaviours among school-going adolescents.

DESIGN AND SETTING

A community-based, national, cross-sectional survey conducted during 2017-2018. The survey was coordinated by the Indian Council of Medical Research-National Centre for Disease Informatics and Research with 10 reputed implementing research institutes/organisations across India in urban and rural areas.

PARTICIPANTS

A multistage sampling design was adopted covering ages between 15 and 69 years-adolescents (15-17 years) and adults (18-69 years). The sample included 12 000 households drawn from 600 primary sampling units. All available adolescents (15-17 years) from the selected households were included in the survey.

MAIN OUTCOME MEASURES

Key NCD risk factors for adolescents (15-17 years)-current tobacco and alcohol use, dietary behaviours, insufficient physical activity, overweight and obesity.

RESULTS

Overall, 1402 households and 1531 adolescents completed the survey. Prevalence of current daily use of tobacco was 3.1% (95% CI: 2.0% to 4.7%), 25.2% (95% CI: 22.2% to 28.5%) adolescents showed insufficient levels of physical activity, 6.2% (95% CI: 4.9% to 7.9%) were overweight and 1.8% (95% CI: 1.0% to 2.9%) were obese. Two-thirds reported being imparted health education on NCD risk factors in their schools/colleges.

CONCLUSION

The survey provides baseline data on NCD-related key risk factors among 15-17 years in India. These national-level data fill information gaps for this age group and help assess India's progress towards NCD targets set for 2025 comprehensively. Though the prevalence of select risk factors is much lower than in many developed countries, this study offers national evidence for revisiting and framing appropriate policies, strategies for prevention and control of NCDs in younger age groups.

Obstructive sleep apnea is highly prevalent in COVID19 related moderate to severe ARDS survivors: findings of level I polysomnography in a tertiary care hospital

Study objectives

Studies have found Obstructive Sleep Apnea (OSA) as a risk factor for increased risk for COVID19 Acute respiratory Distress Syndrome (ARDS); but most of the studies were done in already known patients of OSA. This study was done to find prevalence of OSA in patients with COVID-19 related acute respiratory distress syndrome.

Methodology

A hospital based longitudinal study was conducted among COVID 19 Intensive Care Unit (ICU) survivors. All consecutive COVID19 with moderate to severe ARDS were evaluated for OSA by Level I Polysomnography (PSG) after 4–6 weeks of discharge. Prevalence of OSA and PSG variables {Total sleep time, Sleep efficiency, sleep stage percentage, Apnea Hypopnea Index (AHI), T90, nadir oxygen} was estimated.

Results

Out of 103 patients discharged from ICU during study period (October 2020 to 15 December 2020), 67 underwent Level I PSG. Mean Age was 52.6 ± 10.9 years and mean Body Mass Index was 27.5 ± 6.2 kg/m². Total sleep time was 343.2 ± 86 min, sleep efficiency was 75.9 ± 14.2%. OSA (AHI ≥5) was seen in 65/67 patients and 49 patients had moderate to severe OSA (ie AHI ≥15).

Conclusion

Moderate-severe OSA was highly prevalent (73%) in COVID19 moderate to severe ARDS survivors. Role of OSA in pathophysiology of COVID19 ARDS needs further evaluation.

Foldscope: Diagnostic Accuracy and Feasibility of its Use in National Malaria Control Program

Background

Malaria has been an important public health all over the globe. Although conventional light microscopy is the gold standard of diagnosis, light microscopes are heavy, fragile, costly, and electricity dependent. Rapid diagnostic tests (RDTs) have become more popular but perform badly in temperate climate. This is because the RDT kits require maintenance of cold chain for its optimal use. In this regard, there is a recent interest in handheld malaria microscopy at the point of care in the field setting. Foldscopes are cheap, handy, nonfragile, and use mobile camera for illumination. The purpose of the study was to find whether foldscope can be used in the national vector borne disease control program (NVBDCP) in India.

Methods

Ten laboratory technicians were trained in identifying malaria parasites using foldscope and their mobiles. Later, they were provided with unassembled foldscope to document their test results for the preidentified malaria slides. The blood smears were stained as per the protocol of NVBDCP. The report of the index test (foldscope microscopy) was compared with the reference test (conventional microscopy).

Results

The sensitivity and specificity of the index test was found to be 13.3% (6.257-26.18), specificity of 97.78% (88.43-99.61), positive predictive value 85.71% (48.69-97.43), and negative predictive value 53.01% (42.38-63.38). The devise failure rate and test failure rate were 20% and 11.7%. The kappa agreement between the index and reference microscopy was only 11% and the McNemar P < 0.01.

Conclusion

The ×400 foldscope at its present magnification and illumination cannot be utilized in the field under NVBDCP.

Determinants of lymph node resolution in patients of tubercular lymphadenitis treated with anti tuberculous chemotherapy: A hospital based longitudinal study

INTRODUCTION

The variable course of illness in patients of Tubercular lymphadenitis remains a therapeutic challenge to treating physicians in a significant proportion of patients. This study was aimed to explore the possible determinants which could predict the outcome of this subgroup of patients.

METHODOLOGY

This was a prospective cohort study where 94 patients of TB lymphadenitis were enrolled who could be followed up till the end of treatment. They were evaluated in the beginning and monitored till the end of treatment keeping into account the clinical behaviour of lymph nodes during the course of Anti tubercular chemotherapy.

RESULTS

Out of 94 patients, 60 had their lymph nodes resolved at the end of prescribed treatment duration wheras 34 were classified as partial responders. Another 26 amongst them had their nodes resolved by an extension of continuation phase by 3-6 months. Presence of bilateral and multiple lymph nodes, necrosis on Fine needle aspiration at initial diagnosis and occurrence of Paradoxical upgrading reaction were associated with the partial resolution of lymph nodes at the end of stipulated ATT duration.

CONCLUSION

Treatment duration should be individualized by the treating physicians. Certain parameters mentioned above can be taken as warning signals of patients ending up as partial responders and hence the need of a prolonged extension phase.

Impact of community-based health insurance and economic status on utilization of healthcare services: A household-level cross-sectional survey from rural central India

Background

. Community-based health insurance (CBHI) is a health-financing mechanism based on voluntary membership, risk pooling, with a non-profit objective and relies on social capital as a driving force. It aims to improve equity in healthcare utilization in the community. We did this study to understand if CBHI schemes reach the poor, improve healthcare utilization and protect them from catastrophic health events.

Methods

. Mahatma Gandhi Institute of Medical Sciences (MGIMS), Sevagram, located in Wardha district of Maharashtra, India, runs a variety of CBHI schemes in surrounding villages. Many households (HHs) have opted for these schemes. We conducted a cross-sectional survey of all HHs of 35 villages and collected information about sociodemographics, inpatient healthcare utilization (in previous 5 years), outpatient healthcare utilization (in previous 1 year) and insurance status of the HHs. We derived wealth index based on 33 sociodemographic variables and classified HHs in quintiles of wealth index. We compared the distribution of healthcare utilization variables by insurance status and wealth index and used logistic regression to evaluate if health insurance independently improves healthcare utilization, after adjusting for confounders.

Results

. Of a total of 7261 HHs surveyed, 2210 (30.4%) were uninsured, 4153 (57.2%) were insured under MGIMS CBHI schemes, and 898 (12.4%) had family insurance either from MGIMS or other providers. Insured HHs had a higher wealth index compared to uninsured. Mean (SD) hospitalization episodes in an HH were 0.82 (1.75) among uninsured, 1.13 (1.56) in CBHI insured and 1.21 (1.55) in those with family insurance. Within each category, healthcare utilization was lower for poor HHs (lowest quintile of wealth index) and higher for affluent HHs (higher quintiles of wealth index). Among those who were hospitalized, catastrophic health events were less in CBHI insured (7.9%) compared to uninsured (12.3%). After adjusting for socioeconomic status and other confounders, our data suggest that participating in a CBHI scheme increased odds of utilization of inpatient services (OR 1.18; 95% CI 1.04-1.33) and protected from catastrophic health events (OR 0.52; 95% CI 0.43-0.64).

Conclusion

. CBHI schemes improve healthcare utilization and protect against catastrophic health expenditure among those who get hospitalized. However, there also exists a socioeconomic gradient both in membership and in utilization of healthcare services favouring those who are more affluent.

Improving the capacity of nurses for non-communicable disease service delivery in India: how do they fare in comparison to doctors?

India has witnessed a major shift in morbidity to non-communicable diseases (NCDs) in the last few decades. The service delivery for these long-term conditions has been physician-centred up till now. There is a recent move towards shared care, and nurses are being engaged in the delivery of NCD care. This study was performed in the context of a composite training initiative involving nurses and doctors. Our aim was to compare the performance of nurses with doctors to determine which skills need to be emphasised in future educational programmes. Baseline and end-training knowledge assessments were available from training records. In 2014, of a total of 387 participants from one state in India, 153 were followed up to assess long-term retention of knowledge in various NCD training domains. We found that despite a lower baseline, nurses had a similar attrition in knowledge after training compared to doctors. Results of our study emphasised that nurses can be trained for the primary care needs of NCDs and that both nurses and doctors have retraining needs.

Mental Health Issues in Madhya Pradesh: Insights from National Mental Health Survey of India 2016

BACKGROUND

About 14% of the global mental health burden is contributed by India. However, there exists a disparity in mental health patterns, utilization, and prioritization among various Indian states. The state of Madhya Pradesh is a low performer among Indian states, ranking lower than the national average on the Human Development Index, Hunger Index, and Gross Domestic Product (GDP). The state also performes poorly on other health-related indicators. Objectives of Study: To estimate the prevalence and patterns of mental illnesses in the state of Madhya Pradesh, India.

MATERIAL AND METHODS

This study used the multistage, stratified, random cluster sampling technique, with selection probability proportionate to size at each stage. A total of 3240 individuals 18 years and older were interviewed. The mixed-method study that was employed had both quantitative and qualitative components. The Mini International Neuropsychiatric Interview along with 10 other instruments were used.

RESULTS

The overall weighted prevalence for any mental illness was 13.9%, with 16.7% over the lifetime. The treatment gap for all of the mental health problems is very high (91%), along with high suicidal risk and substance use in the state.

CONCLUSIONS

This study provides evidence of the huge burden of mental, behavioral, and substance use disorders as well as the treatment gap in Madhya Pradesh. This information is crucial for developing an effective prevention and control strategy. The high treatment gap in the state calls for coordinated efforts from all stakeholders, including policy makers, political leaders, health care professionals, and the society at large to give mental health care its due priority. These findings also highlight the need for multi-pronged interventions rooted in health policy directed at reducing the treatment gap in the short term and disease burden in the long run.

Patterns of Glycemic Variability During a Diabetes Self-Management Educational Program

Background: Variations in blood glucose levels over a given time interval is termed as glycemic variability (GV). Higher GV is associated with higher diabetes-related complications. The current study was done with the aim of detecting the sensitivity of various GV indices among individuals with type 2 diabetes mellitus of different glycemic control status. Methods: We performed a longitudinal study among individuals with type 2 diabetes mellitus (T2DM) who were participating in a two-week diabetes self-management education (DSME) program. Participants were categorized by their HbA1c as poor (≥8%), acceptable (7%–8%), and optimal control (<7%). Continuous glucose monitoring (CGM) sensors recorded interstitial glucose every 15 min from day 1. The evaluated GV measures include standard deviation (SD), coefficient of variation (CV), mean amplitude of glycemic excursion (MAGE), continuous overlapping net glycemic action (CONGA), mean of daily difference for inter-day variation (MODD), high blood glucose index (HBGI), and low blood glucose index (LBGI). Results: A total of 41 study participants with 46347 CGM values were available for analysis. Of 41 participants, 20 (48.7%) were in the poor, 10 (24.3%) in the acceptable, and 11 (26.8%) in the optimal control group. The GV indices (SD; CV; MODD; MAGE; CONGA; HBGI) of poorly controlled (77.43; 38.02; 45.82; 216.63; 14.10; 16.62) were higher than acceptable (50.02; 39.32; 30.79; 138.01; 8.87; 5.56) and optimal (34.15; 29.46; 24.56; 126.15; 8.67; 3.13) control group. Glycemic variability was reduced in the poorly and acceptably controlled groups by the end of the 2-week period. There was a rise in LBGI in the optimally controlled group, indicating pitfalls of tight glycemic control. Conclusion: Indices of glycemic variability are useful complements, and changes in it can be demonstrated within short periods.

Patterns of healthcare seeking behavior among persons with diabetes in Central India: A mixed method study

Background:

Management of diabetes is complex and requires multiple lifestyle modifications, drug therapy, and a sustained regular follow-up. Complexities of health-seeking pattern in individuals with diabetes have been poorly characterized.

Objectives:

To understand the health-seeking patterns, and reasons of provider preference and switching among persons with diabetes.

Materials and Methods:

We performed a mixed methods study in an urban slum setting of Bhopal. This urban slum was chosen as being a field practice area of the institute, a complete sampling frame with listing of households, and individuals with chronic disease conditions (including diabetes) was available. To be included in the study, the individual should have been an adult, aged ≥20 years, and diagnosed as type 2 diabetes mellitus. Descriptive statistical analysis of sociodemographic and disease management variables was performed. For qualitative component, interviews were transcribed and primary coding was done by two investigators followed by condensation of codes into themes or categories. The frequency of these content categories was presented with count and proportions.

Results:

In total, 60 individuals with diabetes were interviewed. Of all individuals, 36 (60%) were asymptomatic at the time of the first diagnosis, and 57 (95%) were currently under treatment from some healthcare provider. About 25 (41.6%) switched their first provider and remaining continued with the same provider. Second provider was sought by 9 (36%) of 25 patients. Reasons for switching were perceived nonrelief, cost of care, distance of facility, and behavior of care provider.

Conclusions:

Healthcare provider switching is common among persons with diabetes which has implications on continuity of care.

Correcting inhaler technique decreases severity of obstruction and improves quality of life among patients with obstructive airway disease

Background

Asthma and chronic obstructive lung disease (COPD) together constitute a huge burden on healthcare all around the world. Treatment of these patients is largely dependent on the way the inhalation devices are used. This study aimed at measuring the impact of rectification of inhalation technique on quality of life and severity of obstruction in patients with asthma and COPD.

Materials and Methods

A total of 45 asthma (partly controlled) and 38 patients with COPD (categories B and C) were enrolled after applying optimal exclusion criteria. These patients underwent Asthma Control Test (ACT)/COPD Assessment Test (CAT) questionnaire as a measure of quality of life and forced expiratory volume in one second (FEV₁) as a measure of severity of obstruction at 0 and 4 weeks, respectively.

Results

In asthmatics, the mean FEV₁ improved from 2.0 to 2.15 L after 4 weeks of technique correction (P < 0.001). In addition, the mean ACT scores improved from 18.0 to 20.75 (P < 0.001). In patients with COPD, the mean FEV₁ improved slightly from 1.54 to 1.56 L after 4 weeks of technique correction (P = 0.28). In addition, the mean CAT scores improved from 21.86 to 19.83 (P < 0.001).

Conclusion

Demonstration of correct inhalation technique should be an indispensible part of the treatment prescription of patients with obstructive airway disease. This simple and important task can be undertaken at the level of primary care physicians in a community-based setting to improve patient compliance.

Nocturic obstructive sleep apnea as a clinical phenotype of severe disease

Study Objectives

This study was done to find whether a history of nocturia is associated with severity of obstructive sleep apnea (OSA) and also whether patients with nocturia constitute a separate phenotype of OSA.

Materials and Methods

Retrospective chart review was done in consecutive OSA patients who were diagnosed in sleep laboratory of our institute. Detailed sleep history, examination, biochemical investigations, and polysomnography reports were taken for the analysis. Nocturia was defined as urine frequency ≥2/night.

Results

Of 172 OSA patients, 87 (50.5%) patients had nocturia. On multivariate analysis, a history of nocturia had 2.429 times (confidence interval 1.086-5.434) more chances of having very severe OSA (P = 0.031). Time between bedtime and first time for urination was significantly less in very severe OSA compared to severe OSA and mild-to-moderate OSA (2.4 ± 0.9, 3.1 ± 1.3, and 3.0 ± 1.1 h, respectively) (P = 0.021). Patients with nocturia were older (52.3 ± 11.9 vs. 47.6 ± 12.1 years; P = 0.012), had higher STOP BANG scores (P = 0.002), higher apnea-hypopnea index (AHI) (64.8 ± 35.9 vs. 43.9 ± 29.1; P < 0.001), and higher Epworth sleepiness scale (ESS) (9.2 ± 5.3 vs. 7.7 ± 4.4; P = 0.052) and were more likely to be fatigued during day (P = 0.001). Nocturics had higher body mass index (BMI) (P = 0.030), higher waist, and hip circumference (P = 0.001and 0.023, respectively). Nocturic patients had lower awake SpO₂(P = 0.032) and lower nadir SpO₂ during sleep (P = 0.002).

Conclusions

A history of nocturia (≥2/night) predicts very severe OSA (AHI >60). Nocturic OSA is a phenotype of OSA with more severe AHI, lower oxygen levels, higher BMI, and higher ESS. We believe nocturia can be used for screening in OSA questionnaires, which needs to be validated in further community-based studies.

Learning styles among first professional northern and central India medical students during digitization

BACKGROUND

Learning style is an individual's natural or habitual pattern of acquiring and processing information in learning situations. Different sensory modalities are used by different types of medical students for assimilating the knowledge and information. Currently, the usage of electronic tools for teaching is widespread that can influence learning styles.

METHODS

The purpose of this study was to know the pattern of learners among first- and second-year medical students from different institutions in India. For this purpose, we have used latest English Version 7.0 of the Visual-Aural-Read/write-Kinesthetic.

RESULTS

Analysis was carried out using the IBM SPSS Version 21 software. Numerical variables were summarized by mean and SD or median and IQR as appropriate. Differences in scores among Visual-Aural-Read/write-Kinesthetic-learning styles were tested by Friedman's test with post hoc pair wise comparison. Pattern of learning styles was different, and it was statistically significant (P<0.001). In this study, aural (median score 6) and kinesthetic (median score 6) styles were preferred. Pair-wise comparisons revealed that each style was different from each other except kinesthetic and aural.

CONCLUSION

Results of the study suggest that to improve learning, one should try to use multimodal styles with special emphasis given to auditory and kinesthetic modes especially among first professionals in medical education during digitization.

Lung Ultrasound and Blood Gas-Based Classification of Critically Ill Patients with Dyspnea: A Pathophysiologic Approach

Introduction:

The objective of this study was to classify dyspneic patients and to evaluate outcome variables on the basis of lung ultrasound (LUS) and arterial blood gas (ABG) findings.

Methods:

We performed a retrospective chart-based review in which we included patients with dyspnea admitted to our intensive care unit (ICU) between March 2015 and August 2016. On the basis of LUS (presence of A-lines/B-lines) and ABG (hypoxia/hypercarbia), patients were classified into six groups: (i) metabolic defect (dry lung, no hypoxia); (ii) perfusion defect (dry lung, hypoxia); (iii) ventilation defect (dry lung, hypoxia, and hypercarbia); (iv) ventilation and alveolar defect (wet lung, hypoxia, and hypercarbia); (v) alveolar defect-consolidation ([wet lung] hypoxia, no echocardiographic [ECG] abnormality); (vi) alveolar defect-pulmonary edema (wet lung [usually bilateral], hypoxia, ECG abnormality). The patient's demographic data, sequential organ failure assessment (SOFA) score, need for intubation, vasopressors, form of mechanical ventilation, ICU outcome, and length of stay were noted.

Results:

A total of 244 out of 435 patients were eligible for inclusion in the study. The median age was 56 years. 132 patients (54.1%) required mechanical ventilation, and median SOFA score was 7. Noninvasive ventilation was required in 87.5% of patients with ventilation defect as compared to 9.2% with alveolar defect-consolidation (P < 0.0001). We had 21.7% mortality in patients with alveolar defect-consolidation, 10.8% mortality in patients with metabolic defect, and 8.7% mortality in patients with alveolar defect-pulmonary edema (P < 0.0001).

Conclusion:

This classification gives an organized approach in managing patients with dyspnea. It predicts that patients with alveolar defect-consolidation are most sick of all the groups and need immediate intervention.

Barriers to CPAP Use in India: An Exploratory Study

STUDY OBJECTIVES

To investigate adherence to continuous positive airway pressure (CPAP) therapy and identify barriers to CPAP use among patients with obstructive sleep apnea (OSA) in India.

METHODS

A self-devised semistructured questionnaire (which collected patients' demographic information, socioeconomic position, and information about disease status, symptoms, and complications) was administered to consecutive patients with moderate to severe OSA from June 2015 to August 2016. Patients were grouped according to CPAP device buying behavior (buyers versus nonbuyers) and CPAP compliance behavior (compliant versus noncompliant).

RESULTS

Out of 187 patients with moderate-severe OSA, 79 patients were enrolled for this study. The overall adherence rate (usage > 4 hours per night on > 70% nights) was 30.3%. Among the patients in the buyer group, adherence was 82.7%. Fifty patients did not buy a CPAP device; 30 of these 50 patients (60%) said financial constraints were the most important reason for not buying a CPAP device. Patients without financial constraints had higher chances-odds ratio (95% confidence interval) = 4.85 (1.6-16.1)-of buying a CPAP device than patients with financial constraints. Patients with more severe disease (ie, lower nadir oxygen saturation during sleep, higher apnea-hypopnea index, or presence of obesity hypoventilation syndrome) were more likely to buy and use a CPAP device.

CONCLUSIONS

The main cause of nonuse of CPAP in India is the inability to buy a CPAP device. In patients who are able to buy a CPAP device, adherence was significantly higher (82.7%) compared to adherence in the study's overall population (30.3%). Furthermore, patients with more severe OSA were more likely to buy a device and adhere to CPAP. Patients' behaviors and attitudes are also important barriers in using CPAP. There needs to be increased awareness of the benefits of CPAP therapy among patients.

'Before reaching the last mile'- Knowledge, attitude, practice and perceived barriers related to tuberculosis directly observed therapy among ASHA workers in Central India: A mixed method study

Introduction: Community-based direct observed treatment (DOT) providers are an important bridge for the national tuberculosis programme in India to reach the unreached. The present study has explored the knowledge, attitude, practice and barriers perceived by the community-based DOT providers.

Methods: Mixed–methods study design was used among 41 community-based DOT providers (Accredited Social Health Activist (ASHAs)) working in 67 villages from a primary health center in Raisen district of Madhya Pradesh, India. The cross-sectional quantitative component assessed the knowledge and practices and three focus-group discussions explored the attitude and perceived barriers related to DOT provision.

Result: ‘Adequate knowledge’ and ‘satisfactory practice’ related to DOT provision was seen in 14 (34%) and 13 (32%) ASHAs respectively. Only two (5%) received any amount of honorarium for completion of DOT in last 3 years. The focus-group discussions revealed unfavourable attitude; inadequate training and supervision, non-payment of honorarium, issues related to assured services after referral and patient related factors as the barriers to satisfactory practice of DOT.

Conclusion: Study revealed inadequate knowledge and unsatisfactory practice related to DOT provision among ASHAs. Innovations addressing the perceived barriers to improve practice of DOT provision by ASHAs are urgently required.

Screening of Patients with Chronic Medical Disorders in the Outpatient Department for Depression Using Handheld Computers as Interface and Patient Health Questionnaire-9 as a Tool

Background and Objectives:

Depression, especially in concurrence with chronic medical disorders, is highly prevalent worldwide. An average between 9.3% and 23% of patients with one or more chronic disease have co-morbid depression. This comorbid depression has the worst health scores of all the disease states. Despite this, patients with chronic medical disorders are not commonly screened for depression. Lack of objective screening by health-care providers as well as lack of infrastructure (time/space/personnel) probably contributes to gross underdiagnosis of depression. This issue can be addressed using short objective depression screening score (Patient Health Questionnaire-9 [PHQ-9]) (validated in native languages, e.g., Hindi) and paperless self-administered interface on handheld computer (tablet), which is the objective of the study.

Subjects and Methods:

One hundred consecutive patients with chronic medical disorders visiting our medicine outpatient department were screened for depression using tablets with PHQ-9 Hindi on a self-administered interface.

Results:

The overall prevalence of depression was found to be 25% (95% confidence interval 16.6–34.8). Nearly half of the patients with depression had moderate depression (PHQ-9 score 10–14) while rest had moderately severe or very severe depression (PHQ-9 score >14). Association of depression was not found to be statistically significant with age, duration of disease, gender, the type of disease, or the number of disease. Majority of patients rated ease of the use of tablet interface (on a visual analog scale) as very easy (approx 95%). All the patients were able to complete the tablet screener without assistance, answering all of the questions. The median time of completion with interquartile range was 4 (3–5) min. Majority of the patients (63%) completed the questionnaire within 5 min while rest completed it in 5–10 min.

Conclusions:

It is feasible to use tablets with PHQ-9 questionnaire in native language for screening depression in chronic medical disorders. With high prevalence of comorbid depression, any comprehensive care of patients with chronic medical disorders will not be possible, unless such patients are screened and treated for depression. A self-administered screening questionnaire for depression on handheld tablets can prove to be a handy tool to achieve above aim.

Mapping the Characteristics of Critical Care Facilities: Assessment, Distribution, and Level of Critical Care Facilities from Central India

Background

In low- and middle-income countries such as India, where health systems are weak, the number of available Critical Care Unit (Intensive Care Unit [ICU]) beds is expected to be low. There is no study from the Indian subcontinent that has reported the characteristics and distribution of existing ICUs. We performed this study to understand the characteristics and distribution of ICUs in Madhya Pradesh (MP) state of Central India. We also aimed to develop a consensus scoring system and internally validate it to define levels of care and to improve health system planning and to strengthen referral networks in the state.

Methods

We obtained a list of potential ICU facilities from various sources and then performed a cross-sectional survey by visiting each facility and determining characteristics for each facility. We collected variables with respect to infrastructure, human resources, equipment, support services, procedures performed, training courses conducted, and in-place policies or standard operating procedure documents.

Results

We identified a total of 123 ICUs in MP. Of 123 ICUs, 35 were level 1 facilities, 74 were level 2 facilities, and only 14 were level 3 facilities. Overall, there were 0.17 facilities per 100,000 population (95* confidence interval [CI] 0.14-0.20 per 100,000 populations). There were a total of 1816 ICU beds in the state, with an average of 2.5 beds per 100,000 population (95* CI 2.4-2.6 per 100,000 population). Of the total number of ICU beds, 250 are in level 1, 1141 are in level 2, and 425 are in level 3 facilities. This amounts to 0.34, 1.57, and 0.59 ICU beds per 100,000 population for levels 1, 2, and 3, respectively.

Conclusion

This study could just be an eye opener for our healthcare authorities at both state and national levels to estimate the proportion of ICU beds per lac population. Similar mapping of intensive care services from other States will generate national data that is hitherto unknown.

A study of spatial and meteorological determinants of dengue outbreak in Bhopal City in 2014

BACKGROUND & OBJECTIVES

Dengue epidemics have been linked to various climatic and environmental factors. Dengue cases are often found in clusters; identification of these clusters in early phase of epidemic can help in efficient control by implementing suitable public health interventions. In year 2014, Bhopal City in Madhya Pradesh, India witnessed an outbreak of dengue with 729 recorded cases. This study reports spatial and meteorological determinants and, demographic and clinical characteristics of the dengue outbreak in Bhopal City.

METHODS

A cross-sectional survey of all confirmed cases reported to District Unit of Integrated Disease Surveillance Programme (IDSP), Bhopal was carried out during June to December 2014. Data pertaining to clinical manifestations, health seeking and expenditure were collected by visiting patient's residence. Geographic locations were recorded through GPS enabled mobile phones. Meteorological data was obtained from Indian Meteorological Department website. Multiple linear regression analysis was used to test influence of meteorological variables on number of cases. Clustering was investigated using average nearest neighbour tool and hot-spot analysis or Getis- Ord Gi* statistic was calculated using ArcMap 10.

RESULTS

The incidence of confirmed dengue as per IDSP reporting was 38/100,000 population (95% CI, 35.2- 40.7), with at least one case reported from 73 (86%) of the total 85 wards. Diurnal temperature variation, relative humidity and rainfall were found to be statistically significant predictors of number of dengue cases on multiple linear regressions. Statistically significant hot-spots and cold-spots among wards were identified according to dengue case density.

INTERPRETATION & CONCLUSION

Seasonal meteorological changes and sustained vector breeding contributed to the dengue epidemic in the post-monsoon period. Cases were found in geographic clusters, and therefore, findings of this study reiterate the importance of spatial analysis for understanding the pace of outbreak and identification of hot-spots.

Study of fingerprint patterns to evaluate the role of dermatoglyphics in early detection of bronchial asthma

BACKGROUND

Dermatoglyphics and bronchial asthma (BA) are both influenced by genetic factors. Hence, we assessed the diagnostic potential of correlation between fingerprint pattern and BA.

MATERIALS AND METHODS

The study was carried out in out-patient Department of Pulmonary Medicine of All India Institute of Medical Sciences Bhopal. It included 36 patients of BA and 50 nonasthmatic individuals as controls. The following parameters were studied and analyzed: (a) Whorls, (b) arches, (c) radial loops, (d) ulnar loops, (e) the absolute finger ridge count (AFRC), (f) total finger ridge count (TFRC).

RESULTS

A significant decrease in the mean value of the arches and increase in the mean value of the ulnar loops were observed in BA patients compared to the control group. The mean values of TFRC, AFRC, and whorls were similar in both groups.

CONCLUSION

Evaluation of dermatoglyphic patterns may be useful in identifying patients prone to developing BA.

Some interesting observations regarding TB patient management from a rural area of Madhya Pradesh: TB case series

Despite many serious efforts, tuberculosis (TB) is still a recognized public health problem. The Government of India has adopted the Directly Observed Treatment, Short-Course (DOTS) strategy for the entire country through the Revised National Tuberculosis Control Programme (RNTCP) for the treatment of TB. In this report, we have presented the trajectories for care seeking of two TB cases who suffered from either “patient level delays” or “health system-related delays” in seeking DOTS for the treatment of TB.

Age Related Changes in Autonomic Functions

INTRODUCTION

Autonomic Nervous System (ANS) imbalance may trigger or enhance pathology in different organ systems that varies in different age groups hence objective of present study was to evaluate association of different Age-groups with autonomic functions.

MATERIALS AND METHODS

A cross-sectional study was conducted in 62 healthy volunteers in Department of Physiology LLRM Medical College Meerut, India. Volunteers were divided into three groups as younger (15-45 years), middle (45-60) and elder age (above 60), Autonomic functions were tested in three domains viz. Cardio-vagal, adrenergic and sudomotor functions. Numerical data was summarized as mean and standard deviation and categorical data as count and percentage. ANOVA and Chi-square test were used to find difference among groups, p<0.05 was considered statistically significant.

RESULTS

Mean ± standard deviation OHT(Orthostatic Hypotension Test) among of younger, middle and elder age groups were 8.80±2.28, 13.40±4.64 and 21.82±6.04 respectively which represent decrease in sympathetic functions with age (p<0.001). Cardio-vagal or parasympathetic responses indicated by DBT (Deep Breathing Test) Valsalva and 30:15 ratio of HR response to standing tests has shown statistically significant (p<0.001) decrease in mean response with increasing age. Sudomotor response appeared normal in younger and middle group but was interrupted in more than half of elderly people (p<0.001).

CONCLUSION

Sympathetic responses & para-sympathetic responses have shown the significant decline with increasing age group. Sudomotor responses were partially interrupted in elderly age group.

Assessment of primary care facilities for cardiovascular disease preparedness in Madhya Pradesh, India

Background

Government of India has launched National Program for Prevention & Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS) to address high prevalence of non-communicable diseases (NCDs) in India. Cardiovascular diseases (CVDs) constitute a significant portion of NCD burden. While this program is yet to be launched in all districts of Madhya Pradesh state of India, we performed this study to understand facility-level gaps that need to be addressed to improve CVD services in primary care provided by the public sector.

Methods

This is a cross-sectional questionnaire based study. A standardized questionnaire was self-administered to 85 medical officers from as many primary care facilities from 24 districts of the state. These medical officers were working in two types of primary care facilities – primary health center (PHC) and community health centers (CHC). Facilities were assessed for 36 items in 5 domains (human-resource, equipment, drug supplies, point-of-care tests and laboratory services) with a focus on management of hypertension and diabetes mellitus in primary-care. Each item was to be answered as either present or absent at the facility where medical officer was working. We compared availability of an item across two levels of primary care facilities. All statistical analysis were done using Microsoft Excel.

Results

Availability of facilities was least in laboratory services, and human resource domains followed by drugs, and better in equipment and point-of-care supply domains. Across these domains, availability of items in CHCs was (37.1, 49.0, 56.1, 67.9 and 80.9 % respectively) and in PHCs (11.8, 18.2, 44.2, 55.1, and 55.3 % respectively).

Discussion

Current facility assessment study shows critical gaps in key items required for management of NCDs at primary care level. Human resource and laboratory services need to be strengthened the most, followed by sustained availability of all required drug classes, equipment and related supplies, and upgrading point-of-care testing. There are larger gaps in PHCs, which are level 1 facilities, as compared to CHCs, which are level 2 facilities in primary-care.

Conclusions

Increasing burden of NCDs like hypertension and diabetes mellitus necessitates public health response through health systems. Therefore health system preparedness in form of trained human resources, functional laboratories and well stocked pharmacies are essential in primary care facilities.

Prevalence and Patterns of Coexistence of Multiple Chronic Conditions: A Study from Indian Urban Outpatient Setting

Background:

Chronic diseases are a common cause for seeking care in a hospital, however little is known about prevalence and spectrum of multiple chronic conditions (MCC) in Indian context. Estimates for coexistence of MCC range from one-fourth of all primary care attendees in Spain to two-thirds of all medicare attendees in the United States. This study was designed to estimate the similar prevalence and patterns in an Indian outpatient setting.

Materials and Methods:

This study was performed at All India Institute of Medical Sciences Bhopal between May and June 2013, a hospital which had just started outpatient services in this period. All consecutive patients that presented to Medicine, Neurology, and Orthopedics clinics were sought to be included in the study, and information about their current diagnoses was abstracted from their outpatient records. All patients with one or more chronic disease diagnosis were asked about their monthly out-of-pocket expenditure. We performed a descriptive analysis of the demographic, medical diagnoses, and out-of-pocket expenditure variables.

Results:

A total of 785 patients were included in the study, and 286 (36%) of them had one or more chronic disease diagnosis. Of these, 103 (13%) had a single chronic disease, while 183 (23%) had more than one chronic disease diagnosis. Among those with MCCs, chronic vascular diseases in combination, followed by combinations of chronic vascular and immunological diseases were common patterns. There was a significant rising trend in average out-of-pocket expenditure with increasing number of chronic disease diagnoses.

Conclusion:

Co-existence of multiple chronic diseases is common in those who seek hospital-based care. This fact has important implications for education and clinical decision making in primary care.

Migraine: is it related to hormonal disturbances or stress?

BACKGROUND

Common neurological syndrome (migraine without aura) is more common among women than men. Migraine is among the top 20 causes of disability. Menstruation is known to be a powerful trigger for migraine, and so is stress, but the presentation of headache is similar in both. Also, women are more vulnerable to stress as well as migraine, and this makes a complex relationship of menstruation, stress, and migraine.

OBJECTIVE

This study was done to understand the association of hormonal fluctuation in menstruation and stress with common migraine.

MATERIALS AND METHODS

A cross-sectional comparative study was conducted in 40 young adult females, of whom 20 participants were cases of migraine without aura (18-35 years old), and the remaining 20 participants were age-matched controls. The study was done in Maulana Azad Medical College, New Delhi. Study participants were selected on the basis of International Headache Society (ICHD-IIA1.1) (2004) classification. Study participants with neurological disorders, chronic diseases, and disease suggestive of any hormonal disturbances were excluded. Clinically diagnosed migraine cases were asked to maintain a headache diary and to fill in the Depression Anxiety Stress Scales questionnaire. Biochemical assessment of hormonal status for thyroid-stimulating hormone, triiodothyronine, thyroxine, estrogen, follicle-stimulating hormone, luteinizing hormone, and prolactin was also done on the second day of their menstrual cycle. We used the Mann-Whitney U test to compare hormonal levels and the χ (2) test to compare anxiety- or depression-related stress among the migraine and nonmigraine groups.

RESULTS

Significantly higher values of prolactin were observed in cases (mean ± standard deviation, 152.7 mIU/L±30.5) compared to controls (76.1 mIU/L±8.7), with a P-value <0.001. There was no statistically significant difference observed in levels of thyroid-stimulating hormone (P=0.081), estrogen (P=0.086), luteinizing hormone (P=0.091), or follicle-stimulating hormone (P=0.478). Also, anxiety with stress or depression with stress was significantly higher among the migraine group than the controls (P=0.002). Odds of any stress in migraine were higher in the migraine group than in the nonmigraine group (odds ratio 12, 95% confidence interval 2.7-53.33).

CONCLUSION

Migraine, particularly without aura, in women is mainly associated with stress-related anxiety or depression, and are more susceptible to stress in the premenstrual period.
