Impact of care at foster homes on the health-related quality of life of HIV-infected children and adolescents: a cross-sectional study from India.

PURPOSE: To assess the impact of care at foster homes on the health-related quality of life (HRQOL) of children living with HIV (CLHIV), attending a referral ART Centre, and to compare their HRQOL with children living in their own homes. METHODS: A cross-sectional study was conducted in 144 CLHIV between 5 and 18 years of age, attending a referral ART Centre in South India to assess their HRQOL using the standard PedsQL™ 4.0 questionnaire. Data were then analysed to compare the HRQOL of children living in foster homes to those children living in their own homes. The child report and the parent proxy-report on the child's HRQOL were also compared to see for any differences in their perspectives. RESULTS: 56.25% CLHIV were brought up in different foster homes. In the child's self-report, the mean HRQOL was higher for children living in foster homes [physical score (76.54 ± 12.40), psychosocial score (71.41 ± 12.40) and total score (73.20 ± 11.13)] when compared to children living in their own homes [physical score (75.09 ± 14.76), psychosocial score (70.60 ± 13.48) and total score (72.17 ± 12.00)]. There was no statistically significant difference in the HRQOL between these two groups (p > 0.05). In the parent proxy-report also, there was no statistically significant difference in the HRQOL in all the three scores. The child self-report depicted a significantly higher HRQOL in all the domains compared to the parent proxy-report (p < 0.05). CONCLUSIONS: HRQOL of children living in foster homes is at par with the quality of life enjoyed by children living in their own homes. Foster care manages to provide a reasonable HRQOL in CLHIV, and has become an inseparable component of quality health care delivery for these children.

Changing profile of organisms causing scleral buckle infections: a clinico-microbiological case series.

PURPOSE: To study the microbiological spectrum and in vitro susceptibility of bacterial isolates from explanted scleral buckles and to correlate clinical presentation to the causative agent. METHOD: Medical records of patients who underwent buckle explantation from July 2007 to May 2012 were reviewed retrospectively. Clinical features and microbiological profile were noted and correlated. RESULTS: Twenty of 24 buckles (83.33%) from 24 patients grew 21 isolates. Isolates included 6 acid-fast bacilli (28.57%; atypical mycobacteria = 5, Nocardia asteroides = 1), 5 gram-positive bacilli (23.8%; Corynebacterium spp. = 4, Bacillus sp. = 1), 4 gram-positive cocci (19.0%; Staphylococcus spp. = 4), 2 gram-negative bacilli (9.5%; Pseudomonas aeruginosa = 2), and 4 fungi (19.0%; Aspergillus spp. = 3, Paecilomyces sp. = 1). Acid-fast bacilli and gram-negative bacilli were sensitive to amikacin and gram-positive bacilli and gram-positive cocci to vancomycin. Buckle exposure within 2 years of primary surgery tended to be noninfective (P = 0.06). Fungal or mycobacterial infections were more symptomatic than those with Corynebacterium species. Results of microscopic examination of conjunctival swab in 5 of 7 eyes (71.4%) were consistent with culture of conjunctival swab and explanted buckles. CONCLUSION: Clinical features and microscopic examination of conjunctival swab may give a lead toward the causative organism in suspected buckle infections. Based on these leads, vancomycin and amikacin may be used as the initial empirical therapy.

Petaloid-pattern pigmentary retinopathy: a novel case report.

We report the case of a 6-year-old girl with an unusual petaloid-pattern pigmentary retinopathy associated with nyctalopia and reduction of vision which had been invariably static over the past 5 years. We performed a comprehensive ophthalmic examination including fundoscopy, autofluorescent imaging, electroretinography and optical coherence tomography. There were diffuse retinal pigment epithelium (RPE) washout areas with blotches of pigment distributed in the pattern of a petal with marked chorioretinal atrophy and scar at the fovea. The arterial caliber was normal. Investigations ruled out intrauterine and neonatal infection. Systemically, she was healthy with normal intellect but with 3-month delayed milestones of development. She had used valproic acid for seizure disorder (without any organic central nervous system lesion) from 2-5 years of age. Electroretinography showed extinguished scotopic responses with slight reduction in cone responses. Optical coherence tomography showed a scar with attenuated RPE-choriocapillary complex at the macula. Her clinical profile did not fully match with any previously described pigmentary retinopathies except rod-cone dystrophy and choroidal dystrophy to a certain extent. The pigmentary retinopathy reported here is a combination of a petaloid pattern of pigmentary disturbance, stationary reduction of vision, nyctalopia, normal intellect and marginal delayed milestones. In the absence of such a description in the literature we named this disorder as petaloid-pattern pigmentary retinopathy.

Outcomes of topography-guided PRK/CXL in keratoconus using the NIDEK CXIII system-"Bharat Protocol" (Pilot study).

Purpose: Outcome of topography-guided excimer laser ablation in conjunction with accelerated, high-fluence cross-linking in corneal ecstatic disease using the NIDEK CXIII equipped with CATz algorithm from the FinalFit software-"Bharat Protocol." Methods: Retrospective case record review of 30 eyes of 17 patients of stage 1-3 keratoconus who underwent the procedure was performed. Data collected were for visual acuity, distortion-induced eye pain, and keratometry. Pachymetry, lower order and higher order aberrations, spherical aberrations, and topographic cylinder were documented from by Scheimpflug imaging (Pentacam 70700: Oculus, Wetzlar, Germany). Results: At a minimum follow-up of 6 months (range 6.2-13 months), there was significant improvement in UCVA (P < 0.00001), BCVA (P = 0.0061), decrease in Kmax (P = 0.0349), Ksteep (P < 0.0411), Kflat (P = 0.0099), and pachymetry (P = 0.0001). Significant improvement was also seen in distortion-induced eye pain (27/30 to 2/30; P < 0.00001). A more than two-line improvement in UCVA and BCVA was seen in 23/30 and 17/30 cases, respectively. Ectasia was stabilized in all cases at the last follow-up, and no complications were seen. Conclusions: The "Bharat" Protocol to arrest keratectasia progression and improve corneal regularity is a safe and efficacious alternative as a keratoconus management option. This is the first such study on Nidek Platform for the same.

Prevalence and Determinants of Low Birth Weight in India: Findings From a Nationally Representative Cross-Sectional Survey (2019-21).

INTRODUCTION: Low birth weight (LBW) is an important public health indicator extensively linked to infant and child mortality, especially in lower-middle-income countries (LMICs). Globally, 15.5% of all infants are born with LBW while 95% of these occur in LMICs. This study aims to examine the prevalence and determinants of LBW in India. METHODS: Data were obtained from the fifth National Family Health Survey (NFHS) round conducted during 2019-2021. The study sample included women aged 15-49 years who had a singleton pregnancy in the five years preceding the survey (N=175,240). A bivariate analysis was carried out and a logistic regression model was fitted to assess the maternal determinants affecting the birth weight among newborns. RESULTS: A total of 175,240 mothers were included in the present study. The proportion of newborns with LBW was 17.29% (n=26366, 95% confidence interval [CI] 17.01, 17.57), of which 6% (n=1450, 95% CI 5.61, 6.41) had very low birth weight (less than 1500 g). An increase in the education level of women or wealth index also resulted in significantly reduced odds of LBW in the newborn. However, the number of antenatal care (ANC) visits lacked any statistically significant association with the odds of having a newborn with LBW. CONCLUSIONS: The burden of LBW in India in recent years has remained stable despite impressive economic growth and increased public health spending on food security and nutritional supplementation. Strengthening the quality of ANC services for pregnant women with a focus on sensitization and awareness generation for improving maternal nutrition requires high prioritization.

Perceived Gaps in Academic Training and Expectations From Refresher Training in Primary Care Nurses at an Urban Metropolis in Northern India: A Qualitative Study.

Background Nursing professionals, comprising the largest workforce engaged in the primary healthcare system, play a pivotal role in addressing population health needs. However, gaps in the training of nurses and midwives in lower-middle-income countries may undermine their performance and necessary skill development for fulfilling key population health needs. Substantial challenges exist in improving the regular curricular and refresher training of diplomate nurses and midwives working in primary care facilities and supporting both clinical care and health promotion functions. The study objective was to conduct a gap analysis in the present nursing curriculum and training profile of general duty midwives working in urban primary health facilities and understand their expectations and preferences from the planned refresher training course.  Methods We conducted a qualitative explorative study among General Nursing midwives (GNMs) working in urban primary health facilities in the Gurugram district of Haryana, India to conduct a gap analysis in their present curriculum and training preferences.  Results A total of 17 nurses with a mean (SD) age of 33.52 (4.75) years and an average nursing work experience of 5.35 (0.56) years were interviewed in-depth. Lack of practical applicability, complex study material, inexperienced tutors, and weak English language comprehension were key barriers in the existing nursing curriculum. The nurses expressed willingness to participate in refresher training with varied expectations, although there existed a distinct preference for short, flexible, and blended online-offline modes of training.  Conclusions Strengthening GNM nursing education should be prioritized in Indian health settings with the focus on improving student comprehension through vernacular instruction when feasible, and capacity building of tutors, with avenues for continued training and education. There is also a need for strengthening the curriculum related to key emergent public health challenges related to non-communicable diseases and mental health, as also skills for client and patient counseling and communication.

Impact of incorporating Magnetic Resonance Imaging in FIGO Staging of Primary Carcinoma Cervix: Experience from a tertiary cancer center.

BACKGROUND: International Federation of Gynaecology and Obstetrics (FIGO) staging of carcinoma cervix, although essentially clinical, acknowledges the benefits of MRI. The impact of incorporating MRI in staging of cervical cancer and the discordance between clinical-and MRI-based FIGO staging is not well studied, especially in low- and middle-income countries. AIM: We aim to study the role and accuracy of MRI in staging carcinoma cervix, its correlation with clinical FIGO and histopathological staging with emphasis on how it can change treatment plan. METHODS: Retrospective observational cohort study (n = 193) where MRI details of different staging parameters of the study subjects were compared with clinical FIGO staging and histopathology to assess correlation and agreement between them. Change of clinical FIGO stage and hence treatment plan brought about by incorporating MRI was assessed. RESULTS: MRI had a tumor detection rate of 94.3%, overall staging accuracy of 78.3% and very strong correlation with histopathology (Spearman's coefficient of rank correlation, r = 0.886). Clinical FIGO and MRI had agreement only in 52.8% cases (r = 0.61). Incorporating MRI changed the clinical stage in 47.2% patients and subsequently modified primary treatment plan in 23.3%. CONCLUSION: MRI is highly accurate in evaluating carcinoma cervix and has good correlation with histopathology. Our data shows low agreement between MRI and clinical FIGO staging. Thus, incorporating MRI in FIGO staging has considerable impact in altering treatment decisions and should be offered to all patients for staging carcinoma cervix.

Human mini brains and spinal cords in a dish: Modeling strategies, current challenges, and prospective advances.

Engineered three-dimensional (3D) in vitro and ex vivo neural tissues, also known as "mini brains and spinal cords in a dish," can be derived from different types of human stem cells via several differentiation protocols. In general, human mini brains are micro-scale physiological systems consisting of mixed populations of neural progenitor cells, glial cells, and neurons that may represent key features of human brain anatomy and function. To date, these specialized 3D tissue structures can be characterized into spheroids, organoids, assembloids, organ-on-a-chip and their various combinations based on generation procedures and cellular components. These 3D CNS models incorporate complex cell-cell interactions and play an essential role in bridging the gap between two-dimensional human neuroglial cultures and animal models. Indeed, they provide an innovative platform for disease modeling and therapeutic cell replacement, especially shedding light on the potential to realize personalized medicine for neurological disorders when combined with the revolutionary human induced pluripotent stem cell technology. In this review, we highlight human 3D CNS models developed from a variety of experimental strategies, emphasize their advances and remaining challenges, evaluate their state-of-the-art applications in recapitulating crucial phenotypic aspects of many CNS diseases, and discuss the role of contemporary technologies in the prospective improvement of their composition, consistency, complexity, and maturation.

Therapeutic Strategies for Mutant SPAST-Based Hereditary Spastic Paraplegia.

Mutations of the SPAST gene that encodes the microtubule-severing enzyme called spastin are the chief cause of Hereditary Spastic Paraplegia. Growing evidence indicates that pathogenic mutations functionally compromise the spastin protein and endow it with toxic gain-of-function properties. With each of these two factors potentially relevant to disease etiology, the present article discusses possible therapeutic strategies that may ameliorate symptoms in patients suffering from SPAST-based Hereditary Spastic Paraplegia, which is usually termed SPG4-HSP.

Isolated parapharyngeal cold abscess in a 9-year-old boy.

Tuberculous adenitis presenting as an isolated cold abscess in the parapharyngeal space is very uncommon and has not been reported in the paediatric age group; presentation as a retropharyngeal abscess, however, is well known. Nine-year-old boy with a progressively increasing swelling on the right side of the neck for 2 months was referred with a clinical diagnosis of neuroblastoma. Surgical exploration of the parapharyngeal space by needle aspiration yielded a cheesy material and Mycobacterium tuberculosis was detected by DNA TB PCR. Tuberculosis should always be considered in the differential diagnosis of a cervical swelling in a child.

Outcome of Therapeutic Keratoplasty in Hopeless Microbial Keratitis Cases Otherwise Advised Evisceration.

PURPOSE: To study the outcome of therapeutic keratoplasty in severe microbial keratitis cases otherwise advised evisceration. METHODS: A retrospective, single-center clinical audit included 28 patients with severe microbial keratitis presenting from April 2014 to April 2016. Patients with microbial keratitis either affecting more than 2 quadrants of the limbus and/or cases with infections involving more than 180 mm of the cornea who were advised evisceration by more than one ophthalmologist were included. Cases with endophthalmitis were excluded. At 3 months, the outcome was "success" if resolution of infection occurred without recurrence and evisceration was not required. Success was termed "complete" if best vision was 6/24 or better and "partial" otherwise. The outcome was termed a "failure" if infection recurred in the graft or the eye was eviscerated. RESULTS: Mean age of the patients (male:female, 17:11) was 49.5 years, and the mean duration of symptoms before surgery was 28.6 days. Evisceration was required in 2/28 cases. The outcome was "success" in 22/28 cases (78.6%)-complete (10/22); partial (12/22)-and "failure" in 6/28 cases. The outcome was poorer in general in fungal keratitis (n = 16) than bacterial keratitis (n = 7). CONCLUSIONS: Primary evisceration is best avoided in infections limited to the anterior segment. Even in hopeless cases, every eye deserves a fair chance.

Outcomes of repeat descemetopexy in post-cataract surgery descemet membrane detachment.

PURPOSE: To assess the outcomes of repeat descemetopexy in post-cataract surgery Descemet membrane detachment. DESIGN: Retrospective interventional case series. METHODS: This multicenter, institutional study done between January 2007 and July 2013 included 13 eyes of 13 patients who underwent repeat descemetopexy after a failed initial procedure in post-cataract surgery Descemet membrane detachment. Patients without a minimum follow-up of 1 month were excluded. They underwent repeat descemetopexy with either 100% air or isoexpansile mixture of 14% C3F8. At 1 month, final status of Descemet membrane, final best-corrected visual acuity (BCVA), and incidence of postsurgical complications were noted. RESULTS: Mean age was 63.7 ± 6.6 years; male-to-female ratio, 8:5. Descemet membrane detachment involved the visual axis in all cases. Mean interval between 2 interventions was 5.1 ± 3.1 days. Same gas was used in 9 of 13 patients (air, 4; C3F8, 5). Air was used earlier and C3F8 later in 4 patients. At 1 month, 12 of 13 patients had an attached Descemet membrane and improved mean logMAR BCVA (P = .0036). One case developed postoperative pupillary block and 1 case required endothelial transplantation. CONCLUSION: Repeat descemetopexy for post-cataract surgery Descemet membrane detachment gives good anatomic and visual results and is definitely a worthwhile attempt before a complex surgical procedure like keratoplasty is offered.

Polymerase chain reaction evaluation of infectious multifocal serpiginoid choroiditis.

PURPOSE: To study infectious agents associated with multifocal serpiginoid choroiditis (MSC) based on polymerase chain reaction (PCR) evaluation and specific anti-microbial therapy. METHODS: Retrospective review of medical records. RESULTS: Thirteen patients with MSC were evaluated with PCR for the following organisms: Mycobacterium tuberculosis (MTB), herpes simplex virus 1 (HSV 1), varicella zoster virus (VZV), and cytomegalovirus (CMV). Nine (69.2%) were PCR positive for one or more organisms. Seven (53.8%) were positive for MTB, 3 (23.1%) for CMV (1 positive for both MTB and CMV), and 1 (7.6%) for both HSV 1 and MTB. All 13 patients received anti-TB therapy and corticosteroids. Nine patients completed 6 months follow-up; 6 resolved completely, 2 continued to have active lesions, while 1 CMV PCR-positive patient required additional valgancyclovir therapy. CONCLUSIONS: TB is the most important etiology for MSC in endemic countries. The role of herpes viruses in MSC remains unclear and needs further investigation.

Factors influencing polymerase chain reaction outcomes in patients with clinically suspected ocular tuberculosis.

BACKGROUND: Polymerase chain reaction (PCR) assay can be a useful method for definitive diagnosis in paucibacillary infections such as ocular tuberculosis (TB). In this study, we have evaluated factors affecting PCR outcomes in patients with clinically suspected ocular TB. Patients with clinically suspected ocular TB were investigated by PCR of aqueous or vitreous samples. Three control groups were also tested: group 1 included culture-proven non-tuberculous endophthalmitis, group 2 culture-negative non-tuberculous endophthalmitis, and group 3 patients undergoing surgery for uncomplicated cataract. PCR targeted one or more of following targets: IS6110, MPB64, and protein b genes of Mycobacterium tuberculosis complex. Multiple regression analysis (5% level of significance) was done to evaluate the associations between positive PCR outcome and laterality of disease, tuberculin skin test (TST)/interferon-gamma release assay (IGRA), chest radiography, and type of sample (aqueous or vitreous). The main outcome measures were positive PCR by one or more gene targets, and factors influencing positive PCR outcomes. RESULTS: All 114 samples were tested for MPB64, 110 for protein b, and 88 for IS6110. MPB64 was positive in 70.2% (n = 80) of tested samples, protein b in 40.0% (n = 44), and IS6110 in only 9.1% (n = 8). DNA sequencing of amplicons from four randomly chosen PCR reactions showed homology for M. tuberculosis complex. Of the 80 PCR-positive patients, 71 completed a full course of antitubercular therapy, of which 65 patients (91.5%) had complete resolution of inflammation at final follow-up. Among controls, 12.5% (3 out of 24) in group 1 and 18.7% (6 out of 32) in group 2 also tested positive by PCR. No PCR-positive outcome was observed in control group 3 (n = 25). Multiple regression analysis revealed significant association of positive PCR outcome with bilateral presentation, but not with a positive TST/IGRA, chest radiography, or type of sample (aqueous/vitreous) used. CONCLUSIONS: Careful selection of gene targets can yield high PCR positivity in clinically suspected ocular TB. Bilateral disease presentation but not any evidence of latent systemic TB influences PCR outcomes. False-positive results may be seen in ocular inflammation unrelated to ocular TB.

Degree, duration, and causes of visual impairment in eyes affected with ocular tuberculosis.

BACKGROUND: Ocular tuberculosis (TB) can affect nearly every ocular tissue, leading to a variety of vision-threatening clinical manifestations. The goal of this study is to estimate the degree, duration, and causes of visual impairment in eyes affected by ocular TB. RESULTS: This was a retrospective study of patients diagnosed as ocular TB based on polymerase chain reaction (PCR) for Mycobacterium tuberculosis complex. We applied the World Health Organization definition of visual impairment (VI) to affected eye(s), instead of better-seeing eye. Best-corrected visual acuity (BCVA) of <6/18 and ≥6/60 in the affected eye was classified as moderate VI and <6/60 and ≥3/60 as severe VI. Data collected included presenting and final BCVA of affected eyes and the worst BCVA during the study period. Sixty-one eyes of 40 patients were analyzed. Twenty-five patients (52.1%) had bilateral disease. The mean worst BCVA and mean final BCVA (logMAR) were 1.26 ± 0.87 and 0.61 ± 0.85, respectively, and their difference was highly significant (p < 0.0001, Friedman test). The median worst and final BCVA results were 1.30 (range 0.0 to 3.0) and 0.20 (range 0.0 to 3.0), respectively. The mean duration of follow-up was 98.34 ± 81.81 weeks. Moderate and severe VIs were seen in 14 (22.9%) and 12 (19.7%) eyes, respectively, during the course of follow up. Twenty eyes (32.8%) had BCVA of <3/60. Moderate VI or worse was most commonly seen in eyes with multifocal serpiginoid choroiditis (n = 6; 100%), retinal vasculitis (n = 25; 80.6%), and panuveitis (n = 12; 80%). The mean duration of visual loss was 25.2 ± 42.37 weeks (median 6.43 weeks, range 0 to 206.42 weeks). Vitreous hemorrhage, complicated cataract, and macular scarring were the common causes of VI. CONCLUSION: Ocular TB can result in prolonged visual impairment, more commonly in patients with posterior uveitis or panuveitis.
