RESUMEN

OBJECTIVES: The interpretation of mammograms requires many years of training and experience. Currently, training in mammography, like the rest of diagnostic radiology, is through institutional libraries, books, and experience accumulated over time. We explore whether artificial Intelligence (AI)-generated images can help in simulation education and result in measurable improvement in performance of residents in training. METHODS: We developed a generative adversarial network (GAN) that was capable of generating mammography images with varying characteristics, such as size and density, and created a tool with which a user could control these characteristics. The tool allowed the user (a radiology resident) to realistically insert cancers within different regions of the mammogram. We then provided this tool to residents in training. Residents were randomized into a practice group and a non-practice group, and the difference in performance before and after practice with such a tool (in comparison to no intervention in the non-practice group) was assessed. RESULTS: Fifty residents participated in the study, 27 underwent simulation training, and 23 did not. There was a significant improvement in the sensitivity (7.43 percent, significant at p-value = 0.03), negative predictive value (5.05 percent, significant at p-value = 0.008) and accuracy (6.49 percent, significant at p-value = 0.01) among residents in the detection of cancer on mammograms after simulation training. CONCLUSION: Our study shows the value of simulation training in diagnostic radiology and explores the potential of generative AI to enable such simulation training. CLINICAL RELEVANCE STATEMENT: Using generative artificial intelligence, simulation training modules can be developed that can help residents in training by providing them with a visual impression of a variety of different cases. KEY POINTS: Generative networks can produce diagnostic imaging with specific characteristics, potentially useful for training residents. Training with generating images improved residents' mammographic diagnostic abilities. Development of a game-like interface that exploits these networks can result in improvement in performance over a short training period.

RESUMEN

BACKGROUND: Neuropsychological Rehabilitation (NR) helps manage cognitive deficits in epilepsy. As internationally developed programs have limited applicability to resource-limited countries, we developed a program to bridge this gap. This 6-week caregiver-assisted, culturally suitable program has components of (1) psychoeducation, (2) compensatory training, and, (3) cognitive retraining and is called EMPOWER (Indigenized Home Based Attention and Memory Rehabilitation Program for Adult Patients with Drug Refractory Epilepsy). Its efficacy needs to be determined. METHODS: We carried out an open-label parallel randomized controlled trial. Adults aged 18-45 years with Drug Refractory Epilepsy (DRE), fluency in Hindi and or English, with impaired attention or memory (n = 28) were randomized to Intervention Group (IG) and Control Group (CG). The primary outcomes were objective memory (Auditory Verbal Learning Test), patient and caregiver reported everyday memory difficulties (Everyday Memory Questionnaire-Revised), number of memory aids in use, depression (Hamilton Depression Rating Scale), anxiety (Hamilton Anxiety Rating Scale) and quality of life (Quality of Life in Epilepsy-31). Intention to treat was carried out for group analysis. In the absence of norms necessary for computing Reliable Change Indices (RCIs), a cut-off of +1.0 Standard Deviation (SD) was utilized to identify clinically meaningful changes in the individual analysis of objective memory. A cut-off of 11.8 points was used for quality of life. Feedback and program evaluation responses were noted. RESULTS: The majority of the sample comprised DRE patients with temporal lobe epilepsy who had undergone epilepsy surgery. Group analysis indicated improved learning (p = 0.013), immediate recall (p = 0.001), delayed recall (p < 0.001), long-term retention (p = 0.031), patient-reported everyday memory (p < 0.001), caregiver-reported everyday memory (p < 0.001), anxiety (p = 0.039) and total quality of life (p < 0.001). Individual analysis showed improvement in 50 %, 64 %, 71 %, 57 %, and 64 % of patients on learning, immediate recall, delayed recall, long-term retention, and total quality of life respectively. Despite improvements, themes indicative of a lack of awareness and understanding of cognitive deficits were identified. Overall, the program was rated favorably by patients and caregivers alike. CONCLUSION: NR shows promise for patients with DRE, however larger studies are warranted. The role of cognition in epilepsy needs to be introduced at the time of diagnosis to help lay the foundation for education and acceptance.

RESUMEN

AIMS AND OBJECTIVE: To evaluate the attitudes of Indian nurses towards the importance of family involvement in nursing care and the association between nurse attitudes and sociodemographic characteristics. BACKGROUND: Involving the family in the care process is crucial for delivering family- and patient-centred care and ensuring the best possible patient outcomes. Nevertheless, published literature revealed that the nurses may lack clarity regarding the role of family members in the patient's care, which in turn hinders families' participation in care. DESIGN: Cross-sectional descriptive study. The STROBE checklist was used to report the present study. METHODS: A total of 203 Nurses participated in a prospective cross-sectional study between May 2022 and August 2022. They were recruited through convenience sampling from two tertiary care centres in India. A two-part questionnaire was used to gather the data; the first section contained questions for gathering sociodemographic information, and the second part contained the standardized FINC-NA scale. RESULTS: The mean age of the nurses was (28.08 ± 4.722) years, and their median professional experience was 2.5 (1-5.5) years. Nurses' attitude regarding family's importance in patient care was found to be significantly associated (p ≤ .05) with education level, marital status, religion and hometown region. CONCLUSION: In several items Indian nurses have positive attitudes towards family involvement in care but some of the lower scoring items can present opportunities for focused improvement. Continuing development programmes about family-centered care can constitute important strategies to improve the positive attitudes of nurses towards families in practice. PATIENT AND PUBLIC CONTRIBUTION: No patient or public contribution.

RESUMEN

BACKGROUND: Iron is one of the essential metals that functions as a cofactor in various biological cascades in the brain. However, excessive iron accumulation in the brain may lead to neurodegeneration and may show toxic effects. Quercetin, a pigment flavonoid compound, has been proven to be a potent antioxidant and anti-inflammatory that can inhibit lipid peroxidation during metal-induced neurotoxicity. Although iron-induced neuroinflammation and neurodegeneration have been reported in many studies, but the proof for its exact mechanisms needs to be explored. PURPOSE: The key target of the study was to explore the neuroprotective effect of quercetin after oral exposure of iron in rats and explore its underlying molecular mechanisms. RESULTS: The outcomes of the study have shown that oral exposure to ferrous sulfate may modulate behavioral paradigms such as locomotor activity, neuromuscular coordination, and increased anxiety level. The pro-inflammatory cytokines (TNF-α, IL-1ß and IL-6), apoptotic protein (caspase 3), beta-amyloid and phosphorylated tau were found to be increased on iron exposure. Also, the expressions of ferritin heavy and light chain, BACE-1 and GFAP expressions were altered. These behavioral, structural, and biochemical alterations in the brain were significantly and dose-dependently reversed by treatment with quercetin. CONCLUSION: The current study provides a fundamental understanding of molecular signaling pathways, and structural proteins implicated in iron-induced neurotoxicity along with the ameliorative effects of quercetin.

RESUMEN

The problem of antibiotic resistance among pathogenic bacteria has reached a crisis level. The treatment options against infections caused by multiple drug-resistant bacteria are shrinking gradually. The current pace of the discovery of new antibacterial entities is lagging behind the rate of development of new resistance. Efflux pumps play a central role in making a bacterium resistant to multiple antibiotics due to their ability to expel a wide range of structurally diverse compounds. Besides providing an escape from antibacterial compounds, efflux pumps are also involved in bacterial stress response, virulence, biofilm formation, and altering host physiology. Efflux pumps are unique yet challenging targets for the discovery of novel efflux pump inhibitors (EPIs). EPIs could help rejuvenate our currently dried pipeline of antibacterial drug discovery. The current article highlights the recent developments in the field of efflux pumps, challenges faced during the development of EPIs and potential approaches for their development. Additionally, this review highlights the utility of resources such as natural products and machine learning to expand our EPIs arsenal using these latest technologies.

RESUMEN

Multiple parallel factors are frequently interrogated with various toxic radicals which are abundantly generated in the liver, heart, and pancreas in stress conditions. They are actively involved in the development of diabetes and metabolic aberrations. However, whether over-activation of GDF-15mRNA and influxes of iron-by-iron trafficking genes are directly suppressing the Nrf-2 gene in patients with diabetes and metabolic aberrations in context with undiagnosed individuals with diabetes and metabolic aberrations? Therefore, we have investigated inter and intra- related Zip8/14 mRNA, GDF-15mRNA, and Nrf-2 mRNA expressions in diabetes and metabolic syndrome as it is expected to be up to 134 million by 2045 in India. We recruited 120 subjects from the Department of Medicine, Endocrinology and Metabolic Clinic, All India Institute of Medical Sciences, New Delhi, India. Various investigations related to anthropometry, nutritional, hematological, biochemical, cytokine, and oxidative stress were measured in diabetes, metabolic syndrome, diabetes with metabolic aberration, and healthy controls. Relative expression of GDF-15, ZIP8, ZIP14, Nrf-2, and housekeeping genes was done in all subjects. Stress-responsive cytokines are highly expressed in patients with metabolic aberration with respect to body weight, IR, waist circumference, and fat mass. IL-1ß, TNF-α, and IL-6 levels were significantly higher in metabolic syndrome, whereas Adiponectin levels were profoundly lower side. MDA levels were significantly raised in diabetes with metabolic syndrome while SOD activities were lowered (p = 0.001). GDF-15 mRNA expression was 1.79-fold upregulated in group III as compared with Group I while 2-threefold down-regulation of Nrf-2 expression was observed in diabetes with metabolic aberration groups. Zip 8 mRNA expressions were downregulated (p = 0.014), and Zip 14 mRNA expressions were upregulated (p = 0.06) in diabetes and metabolic aberrations. The association of GDF-15 and Nrf-2 mRNA expression was found contradictory and highly interlinked with ROS. Zip 8/14mRNA expressions were also dysregulated in diabetes and metabolic-associated complications.

RESUMEN

BACKGROUND OBJECTIVES: Polycystic ovary syndrome (PCOS) is characterized by chronic ovulatory dysfunction, hyperandrogenism and polycystic ovary morphology (PCOM). Although hyperandrogenism is one of the major features of PCOS, it is rarely observed in southeast Asia. Recently, however, there has been growing evidence on association of anti-Müllerian hormone (AMH) with PCOS. The objective of this study was to investigate the diagnostic potentials of AMH in PCOS individuals. METHODS: This case-control study included a total of 131 women with PCOS and 49 healthy controls who were enrolled after the exclusion of secondary causes of PCOS. Serum AMH was measured using an ultra-sensitive AMH ELISA kit in addition to other diagnostic biomarkers. Statistical analyses was carried out using the Student's t test, Wilcoxon rank-sum test, receiver operating characteristic (ROC) curve analysis, Spearman's rank correlation test and multivariable binary logistic regression analysis. RESULTS: The median AMH values were 8.5 ng/ml and 2.5 ng/ml in the study group and controls, respectively ( P <0.001). The normal cutoff value of 4.1 ng/ml for AMH was derived from ROC curve analysis. With a 4.1 ng/ml cut-off value, high levels of AMH was found in about 84 per cent of PCOS cases. However, no significant difference in AMH level was noted between age groups (<20 vs . ≥20 yr), body mass index (BMI) (<25 vs . ≥25 kg/m 2 ) and PCOM types. The area under the ROC curve (AUC) for AMH yielded diagnostic range values. In total PCOS cases, AUC was 0.93 (95% CI: 0.88 and 0.96), and in phenotype A PCOS cases, AUC was 0.96 (95% CI: 0.91 and 0.98). The correlation test also showed no association with BMI, the FG score, PCOM, free androgen index, androstenedione, dehydroepiandrosterone sulphate and luteinizing hormone. However, a weak correlation was observed with testosterone in total PCOS cases and with DHT as well as age in phenotype A PCOS cases. The prediction model for PCOS using multivariable binary logistic regression analysis showed AMH as the best marker. INTERPRETATION CONCLUSIONS: The results of this study suggest that AMH can be considered as the most promising biomarker in PCOS women, particularly with phenotype A and phenotype D.

RESUMEN

INTRODUCTION: In resource-limited settings, obstructive sleep apnea (OSA) often goes undiagnosed as polysomnography (PSG) is expensive, time-consuming, and not readily available. Imaging studies of upper airway have been tried as alternatives to PSG to screen for OSA. However, racial differences in upper airway anatomy preclude generalizability of such studies. We sought to test the hypothesis that ultrasonography (USG), an inexpensive, readily available tool to study soft tissue structures of the upper airway, would have predictive value for OSA in South Asian people. METHODS: Adult patients with sleep-related complaints suspicious for OSA were taken for overnight PSG. After the PSG, consecutive patients with and without OSA were studied with submental ultrasonography to measure tongue base thickness (TBT) and lateral pharyngeal wall thickness (LPWT). RESULTS: Among 50 patients with OSA and 25 controls, mean age was 43.9 ± 11.4 years, and 39 were men. Patients with OSA had higher TBT (6.77 ± 0.63 cm vs 6.34 ± 0.54 cm, P value = 0.004) and higher LPWT (2.47 ± 0.60 cm vs 2.12 ± 0.26 cm, P value = 0.006) compared to patients without OSA. On multivariate analysis, TBT, LPWT, and neck circumference were identified as independent factors associated with OSA. These variables could identify patients with severe OSA with a sensitivity of 72% and a specificity of 76%. CONCLUSION: Patients with OSA have higher tongue base thickness and lateral pharyngeal wall thickness proportionate to the severity of the disease, independent of BMI and neck circumference. These findings suggest that sub-mental ultrasonography may be useful to identify patients with severe OSA in resource-limited settings.

RESUMEN

To determine the cardiopulmonary changes in the survivors of acute COVID-19 infection at 3-6 month and 6-12 month. We followed up 53 patients out of which 28 (52%) had mild COVID-19 and 25 (48%) had severe COVID-19. The first follow-up was between 3 month after diagnosis up to 6 month and second follow-up between 6 and 12 month from the date of diagnosis of acute COVID-19. They were monitored using vital parameters, pulmonary function tests, echocardiography and a chest computed tomography (CT) scan. We found improvement in diffusing capacity for carbon monoxide (DLCO) with a median of 52% of predicted and 80% of predicted at the first and second follow-up, respectively. There was improvement in the CTSS in severe group from 22 (18-24) to 12 (10-18; p-0.001). Multivariable logistic regression revealed increased odds of past severe disease with higher CTSS at follow-up (OR-1.7 [CI 1.14-2.77]; P = 0.01). Correlation was found between CTSS and DLCO at second follow-up (r2 = 0.36; p < 0.01). Most of patients recovered from COVID-19 but a subgroup of patients continued to have persistent radiological and pulmonary function abnormalities necessitating a structured follow-up.

RESUMEN

OBJECTIVES: The frequency, risk factors, and impact on survival of hemorrhage into (peri)pancreatic collections in patients with acute pancreatitis (AP) has not been well studied. The study was designed to evaluate the risk factors for hemorrhage, successful hemostasis and its effect on in-hospital mortality. METHODS: In a prospective cohort study for prediction of severity of AP, the incidence, risk factors, and outcomes of pancreatic hemorrhage were analyzed. Patients with significant hemorrhage were managed according to a predefined protocol including endovascular intervention. RESULTS: Out of 363 patients hospitalized during the study-period, 33(9%) patients developed hemorrhage. Median time from onset of AP to hemorrhage was 59(45-68) days. The cause of hemorrhage was arterial in 19(57.5%) patients and unlocalized in 14(42.5%) patients. Hemorrhage was managed by conservative approach in 7 (21.2%), radiographic angioembolisation in 16 (48.5%), radiographic angioembolisation followed by surgery in 3 (9.1%), and surgery in 7 (21.2%) patients. Persistent organ failure [aHR 2.3 (1.1-5.1), p = 0.03], use of large bore (>20 Fr) catheter for initial drainage [aHR 3.9 (1.7-9.1), p = 0.001] and extensive (>50%) necrosis [aHR 3.1 (1.4-6.9), p = 0.005] were significant risk factors for hemorrhage. Hemorrhage was an independent predictor of mortality [aHR 2.0 (1.2-3.4), p = 0.008] in addition to persistent organ failure (aHR 12.1 (5.7-25.8), p < 0.001). In-hospital mortality in patients with hemorrhage was 22/33 (66.7%) vs. 81/330 (25%) in no hemorrhage group [p <0.001]. CONCLUSION: Pancreatic hemorrhage occurs later in the course of acute pancreatitis in relatively sicker group of patients with organ failure and extensive necrosis, and is independently associated with a higher risk of in-hospital mortality.

RESUMEN

INTRODUCTION: Recent literature on managing traumatic duodenal injuries suggests the superiority of primary repair. We hypothesized that duodenal trauma repair by primary closure might not be a safe strategy in an environment dealing predominantly blunt injuries with limited resources. METHODS: Data analysis was done from the prospectively maintained trauma registry. The study period chosen was from January 1, 2014 to December 31, 2018. Data of 63 patients were analyzed for demographics, injuries, management, and outcome. Logistic regression was used to identify mortality predictors. RESULTS: The most common mechanism of injury was blunt (56/63, 88.9%). Forty (63.5%) patients had associated intraabdominal injuries. The most common American Association for the Surgery of Trauma grade of injury to the duodenum was three in 21 patients. Univariate analysis showed that mortality was associated with hypotension on presentation, higher duodenal grade, associated abdominal vascular injuries, primary closure, and duodenal leak. Logistic regression showed associated associated abdominal vascular injuries, primary closure, and leak remained significant predictors of mortality. CONCLUSIONS: Primary repair was found to be an independent predictor of mortality. A patient's physiology is a critical determinant of the outcome. Liberal use of tube duodenostomy over primary repair seems reasonable for blunt duodenal injury management.

RESUMEN

PURPOSE: The key element in managing postoperative facial nerve (FN) injuries is timely diagnosis and intervention as indicated. The purpose of this study was to measure and compare evoked electromyography (EEMG) and clinical assessment in terms of the recovery of the injured FN in operated temporomandibular joint ankylosis (TMJA) cases. METHODS: The investigators designed a prospective cohort study in the primary operated TMJA patients. The primary predictor variable was the technique used to assess FN function, House-Brackmann Facial Nerve Grading System (HBFNGS) or EEMG. The primary outcome variable was time to FN recovery. The FN recovery was assessed in different time points (1 week, 1 month, 3 months, and 6 months). Age, gender, side (unilateral/bilateral), type of ankylosis (Sawhney's classification), and operating time were kept as covariates. Categorical variables were analyzed using Fisher's exact test. Multilevel survival analysis was performed considering the subject as cluster to perform Kaplan-Meier analysis and compute the hazards ratio using the Cox-regression method with adjustment for covariates. P <0.05 was set as statistically significant. RESULTS: The study sample composed of 43 (69 sides) TMJA cases who underwent surgery developed iatrogenic FN injury in 10 cases (14 sides [9 right; 5 left]). The incidence of FN injury was 20.3% (14/69). Sawhey's type III/type IV ankylosis and the operating time for more than 2 hours showed a statistically significant (p<0.05) increase in FN injury. The mean duration to detect FN recovery by EEMG was 9 days (95% confidence interval, 5 to 12 days), but the HBFNGS took 161 days (95% confidence interval, 141 to 181 days). The chance of early detection by EEMG was 18.6 times more than the chance by the HBFNGS (Cox-hazard ratio, 18.6). CONCLUSIONS: To conclude, EEMG is a noninvasive and reliable tool that detects FN recovery much earlier than the HBFNGS in the postoperative TMJA cases.

RESUMEN

BACKGROUND: Health systems responsiveness is the key to addressing infectious disease threats such as pandemics. The paper outlines an assessment of health systems resilience by exploring the association of health systems and Global Health Security (GHS) parameters with case load and mortality resulting from COVID-19 across 203 countries using an ecological design. METHODOLOGY: Correlation analysis was performed to assess the relationship of each of the indicators with COVID 19 cases and deaths per million population. Stepwise multiple regression models were developed to determine the predictors of COVID-19 cumulative cases and deaths per million population separately. RESULTS: Global health security indicators seemed to have a strong association when analyzed individually but those did not necessarily translate into less burden of cases or deaths in the multivariable analysis. The predictors of cumulative deaths per million population included general government expenditure on health as a proportion of general government expenditure, responsiveness of the system to prevent the emergence and release of pathogens and governance related voice and accountability. CONCLUSION: To conclude, health financing parameters and preventive activities with regard to emergence of pathogens were better predictors of cumulative COVID-19 cases and deaths per million population compared to other health systems and global health security indicators.

RESUMEN

Aim: To characterize Th1/Th2/Th17 cytokine profile (IL-2, IL-4, IL-6, IL-10, TNF-α, IFN-γ, and IL-17A) among different stages of COVID-19 infection. Methods: This was a cross-sectional study which included six healthy individuals and 68 patients who were admitted with COVID-19 in the Department of Medicine, at All India Institute of Medical Sciences, New Delhi, from July 2020 to September 2020. Patients were categorized into mild, moderate, and severe COVID-19 groups, and serum samples were drawn for the measurement of Th1/Th2/Th17 cytokines (IL-4, IL-6, IL-10, TNF-α, IFN-γ, and IL-17A) which was done by BD™ Cytometric Bead Array. Results: All the cytokines showed dynamic expression in the COVID-19 group, of which only IL-6 was statistically significant. Among the three severity groups of COVID-19, increased severity did not transform into increased cytokine level, with the exception for IL-6, which was statistically significant. Conclusions: In our small sample study, six cytokines expressions were evaluated however most of them were elevated in COVID-19 patients but were not statistically significant except IL-6.

RESUMEN

INTRODUCTION: There are limited data on the effect of chronic pancreatitis (CP) on pregnancy outcomes and vice versa. Our aim was to evaluate the clinical trajectory of CP during pregnancy and its effect on pregnancy outcomes. METHODS: All female patients of child-bearing age (≥15 years) diagnosed with CP were studied from January 2004 to July 2019. The change in frequency of painful episodes was assessed before, during, and after pregnancy. Maternal and fetal outcomes were compared between pregnant women (early onset) and women presenting with CP after completion of all pregnancies (late onset). RESULTS: Of 187 women with CP, pregnancy outcomes and clinical course were assessed in 99 patients. The frequency of painful exacerbations was significantly lower during pregnancy compared with prepregnancy and postpregnancy periods (P < 0.001). The median pain score decreased significantly to 0 (0-2) during pregnancy from 3 (0-6) before conception and increased to 4 (0-8) after pregnancy (P = 0.002). Women with early onset CP (n = 57) had their first child later and had fewer pregnancies compared with those with late onset CP (n = 42). There was no difference in maternal outcomes such as gestational diabetes, hypertension, and preterm delivery, and fetal outcomes such as abortion, low birth weight, and still birth between the groups. There was no reported congenital anomaly. DISCUSSION: Younger patients with CP had later and fewer pregnancies, but there was no increased risk of adverse maternal and fetal outcomes. The clinical course of CP was usually benign during pregnancy with decreased frequency and severity of pain.

RESUMEN

Background & objectives: In the present scenario, the most common sample for diagnosis of COVID-19 by reverse transcription polymerase chain reaction (RT-PCR) is nasal and throat swab (NTS). Other sampling options such as gargle lavage have found limited application in clinical use mostly because of unavailability of an appropriate gargling liquid. This study was conducted to assess the stability of SARS-CoV-2 RNA in normal saline at 4°C that can serve as a gargling liquid as well as a transport medium. The study also looked at the agreement between NTS and gargle lavage/saliva for the detection of SARS-CoV-2. Methods: In 29 consecutive real-time RT-PCR (rRT-PCR) positive COVID-19 patients, paired NTS, gargle and saliva samples were taken. Samples were processed by rRT-PCR for the detection of SARS-CoV-2 RNA. To assess the SARS-CoV-2 RNA stability in normal saline, gargle lavage specimens were divided into two aliquots; one subset of the specimen was run within 4-6 h along with the routine samples (NTS and saliva) and the other subset was stored at 4°C and processed after 24-30 h. Agreement between cycle threshold (Ct) values from both the runs was compared using Bland-Altman (BA) analysis. Results: The positivity rates of rRT-PCR in NTS, saliva and gargle lavage samples were 82.7 (24/29), 79.3 (23/29) and 86.2 per cent (25/29), respectively. BA plot showed a good agreement between the Ct values of fresh and stored gargle samples, stipulating that there were no significant differences in the approximate viral load levels between the fresh and stored gargle lavage samples (bias: E gene -0.64, N gene -0.51, ORF gene -0.19). Interpretation & conclusions: Our study results show stability of SARS-CoV-2 RNA in the gargle samples collected using normal saline up to 24-30 h. Gargle lavage and saliva specimen collection are cost-effective and acceptable methods of sampling for the detection of SARS-CoV-2 RNA by rRT-PCR. These simplified, inexpensive and acceptable methods of specimen collection would reduce the cost and workload on healthcare workers for sample collection.

RESUMEN

OBJECTIVE: To identify the risk factors for glaucoma progression, especially the association with myopia, among treated juvenile open angle glaucoma (JOAG) patients. METHODS: Glaucomatous progression was analysed in the eyes of JOAG patients with at least 5-years of follow up in this retrospective study. Baseline variables such as age, inheritance pattern, baseline intraocular pressure (IOP), baseline central corneal thickness, visual acuity, baseline refractive error, spherical equivalent (SE) and duration of follow-up were noted. Stereoparametric global trend analysis and Moorfields Regression Analysis on confocal scanning laser ophthalmoscopy were used to detect progression. Variables associated with glaucoma progression, with respect to progressors (PG) and non-progressors (NPG) were analysed. Since both eyes of a patient were taken for analysis, a generalised estimating equation method was used to correct the bias. RESULTS: Among 74 eyes (37 subjects), glaucoma progression was noted in 11 eyes (14.9%) of 8 patients, with a median time to progression of 7.4 years (range 5-15.5 years). For myopes (SE ≤ -1.00 D), glaucoma progression was 18 times more likely than mild and no myopes (>-1DS) (p = 0.03, 95% CI: 1.14, 217.44). The prevalence of myopia in the JOAG, PG and NPG cohorts was 70.3%, 87.5%, and 65.5%, respectively. Myopia progression was noted at follow up in 70% patients. One-unit increase in baseline vertical cup disc ratio, 1 mmHg increase in IOP fluctuations and 1 dB year-1 depression of visual field were associated with 0.44, 0.06 and 0.07 D year-1 increases in the rate of myopia progression, respectively. CONCLUSIONS: JOAG progressors had a greater baseline myopic refraction and a faster myopia development over time. The development of myopia in JOAG eyes could be an indicator of glaucoma progression, and hence progressing myopic (≤-1 D) JOAG patients should be followed up more rigorously.

RESUMEN

Plasmodium infections are co-endemic with infections caused by other agents of acute febrile illnesses, such as dengue virus (DENV), chikungunya virus, Leptospira spp., and Orientia tsutsugamushi. However, co-infections may influence disease severity, treatment outcomes, and development of drug resistance. When we analyzed cases of acute febrile illness at the All India Institute of Medical Sciences, New Delhi, India, from July 2017 through September 2018, we found that most patients with malaria harbored co-infections (Plasmodium mixed species and other pathogens). DENV was the most common malaria co-infection (44% of total infections). DENV serotype 4 was associated with mild malaria, and Leptospira was associated with severe malaria. We also found the presence of P. knowlesi in our study population. Therefore, in areas with a large number of severe malaria cases, diagnostic screening for all 4 DENV serotypes, Leptospira, and all Plasmodium species should be performed.

RESUMEN

BACKGROUND: Accurate diagnosis of anemia by community workers using a point-of-care device is a challenge. The objective of the study was to establish the diagnostic accuracy of point-of-care devices for detecting anemia in community settings. METHODS: It was diagnostic accuracy study with cross-sectional design on adult patients attending the outpatient department of rural/ urban health centres of Medical colleges from India. The index tests were HemoCue, TrueHb, Massimo's device and spectroscopic device, compared against autoanalyzer (gold standard). Accuracy was expressed by sensitivity, specificity, likelihood ratios, predictive values, area under the curve (AUC) and levels of agreement. For the diagnostic accuracy component, 1407 participants were recruited with a minimum of 600 for each device. An additional 200 participants were considered to elucidate the performance of devices in different weather conditions. RESULTS: HemoCue and TrueHb performed better than Massimo and spectroscopic devices. Detection of anemia by technicians was similar between TrueHb and HemoCue (AUC 0.92 v/s 0.90, p > 0.05). Community workers performed better with Hemocue for detecting anemia compared to TrueHb (AUC 0.92 v/s 0.90, p < 0.05). For detection of severe anemia, accuracy of TrueHb was significantly better with technicians (AUC 0.91 v/s 0.70; p < 0.05) and community workers (AUC 0.91 v/s 0.73; p < 0.05). HemoCue showed a bias or mean difference (95%CI) of 0.47 g/dl (0.42, 0.52) for all values, and 0.92 g/dl (0.82, 1.03) for severe anemia. For TrueHb, it was - 0.28 g/dl (- 0.37, - 0.20) for all readings, and 0.06 g/dl (- 0.52, 0.63) for severe anemia. TrueHb appeared to be more consistent across different weather conditions, although it overestimated Hb in extreme cold weather conditions. CONCLUSION: For detection of anemia, True Hb and HemoCue were comparable. For severe anemia, True Hb seemed to be a better and feasible point-of-care device for detecting anemia in the community settings.

RESUMEN

BACKGROUND: Infant and child feeding practices are a prevalent challenge in Haryana. OBJECTIVES: The present study aimed to determine factors associated with non-initiation of breastfeeding within 1 h of birth, no exclusive breastfeeding (EBF) and no continued breastfeeding in Haryana. METHODS: National Family Health Survey-4 data for the state of Haryana was used for analysis. The outcomes were non-initiation of breastfeeding within 1 h of birth, no EBF, and no continued breastfeeding. Independent variables were categorized as sociodemographic, maternal, and child level factors. Each category of factors was added step-by-step to the logistic regression model for multivariable analysis. RESULTS: Delayed initiation of breastfeeding was higher among poorer wealth quintiles. Home deliveries (adjusted odds ratio [AOR] = 1.90, 95% confidence interval [CI]-1.27-2.84), cesarean section (AOR = 2.22, 95% CI-1.46-3.40), body mass index (BMI) >25 kg/m2 (AOR = 1.62, 95% CI-1.13-2.33), and not receiving postnatal check-up (AOR 1.36, 95% CI-1.40-1.78) increases likelihood of delayed initiation of breastfeeding beyond 1 h of birth. Increased risk of non-EBF was associated with no postnatal check-ups and BMI >25 kg/m2. Risk of discontinuation of breastfeeding was significantly high with birth interval of <2 years (AOR = 1.52, 95% CI-1.08-2.14) and if babies did not receive postnatal check-up (AOR = 1.54, 95% CI-1.04-2.27). CONCLUSION: The study highlighted need for focused approach to counsel overweight/obese mothers, cesarean section, and home delivered mothers. Community awareness, adequate birth spacing, and postnatal visits are vital for improving exclusive and continued breastfeeding practices. Communities and health-care providers should provide adequate support to mothers for breastfeeding during the antenatal and postnatal periods.
