Better Social-emotional Behavior in Young Nepali Children is Associated with Household Wealth, Child Age, and Family Participation in a Community Development Intervention.

Background Mental health and behavior problems are under-recognized in low- and middleincome countries, especially in young children. Early identification of these problems could encourage governments to address the shortages of child mental health professionals and promote early intervention programs to help children achieve their full developmental potential. Objective Describe the social-emotional development of young rural Nepali children; explore risk factors for poor development. Method The study was embedded in a longitudinal intervention trial comparing control households with those who received training in family nutrition+livestock management (Partial Package) or family nutrition+livestock management+community mobilization (Full Package). At midline, enumerators completed a 145-item household questionnaire, child anthropometry, and Administered the Ages and Stages Questionnaire-Social-Emotional (ASQ-SE) to all enrolled children age 33-47 months (n=310). Bivariate and regression analyses examined the relationship of child and household risk factors to administered the Ages and Stages QuestionnaireSocial-Emotional scores. Result Administered the Ages and Stages Questionnaire-Social-Emotional scores were below age cutoffs in 24% of children, suggesting worse social-emotional development. In bivariate analyses and the adjusted linear regression model, older child age, greater household wealth, and Full Package Intervention status were all associated with better social-emotional development scores. Partial Package Intervention status was associated with worse scores. Conclusion The Administered the Ages and Stages Questionnaire-Social-Emotional is a potential tool to assess child social-emotional development in the context of household and community level interventions. Further work is necessary to validate the administered the Ages and Stages Questionnaire-Social-Emotional and similar tools in Nepal, and to better understand the prevalence of challenges to optimal socialemotional development in young children in order to use this information to design and monitor needed interventions.

First-Generation SARS-CoV-2 Vaccines: A Comparative Analysis between Vaccinated and Unvaccinated Hospitalized Patients Infected with SARS-CoV-2.

Background Severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) variants, which have emerged due to several mutations in spike protein, have a potential to escape immune protection provided by the first-generation vaccines, thereby resulting in breakthrough infections. Objective To identify the socio-demographic factors, clinical features, and outcomes in both vaccinated and unvaccinated hospitalized patients infected with SARS-CoV-2. Method Socio-demographic details, clinical features, and the outcomes among fully vaccinated (double for Covishield/AstraZeneca and BBIBP-CorV and single for Janssen), partially vaccinated, and unvaccinated hospitalized patients with coronavirus disease of 2019 (COVID-19) were collected and analyzed using SPSS version 17. Result Among the hospitalized COVID-19 patients (n=299), 175 (58.5%) patients received a single-dose, 82 (27.4%) double-dose, and 124 (41.5%) did not receive any dose of the COVID-19 vaccines. The risk of SARS-CoV-2 infection when compared between vaccinated and unvaccinated patients was found to be associated among professional degree holders (23.4% versus 9.7%) (p<0.05), professional workers (43.4% vs. 25.0%) (p<0.05), hospitalization to general ward (76.6% vs. 72.6%) (p<0.05), and presence of multiple symptoms (> or equel 3) (86.8% vs. 75.0%) (p>0.05) and comorbidities (> or equal 2) (15.5% vs. 13.7%) (p>0.05). Despite such approximate incidences, the risk of in-hospital mortality among the vaccinated patients was reduced (0.6% vs. 3.2%) (p>0.05), when compared to the unvaccinated patients. The risk of in-hospital mortality was associated with the older age and the presence of multiple comorbidities including bronchial asthma, diabetes, and hypertension. Conclusion Full or partial vaccination against the SARS-CoV-2 variants of concerns might be effective in preventing in-hospital mortality among COVID-19 patients.

Gaming Disorder among Medical College Students during COVID-19 Pandemic Lockdown.

Background The frequent lockdown in Nepal during COVID-19 pandemic had brought various kinds of complexities such as stress among college students. This situation had created uncertainty of future academic career of undergraduate students in medical colleges. Some previously published literature showed gaming as a coping mechanism against stress. Objective To assess the gaming behavior of Medical college students during lockdown in COVID-19 pandemic. Method A cross-sectional study was conducted during lockdown period of July to August 2020. A total of 412 college students were enrolled. Online Google forms were shared to all the eligible students through email, viber and messenger with the help of class representative. Collected data were analyzed in SPSS version 20.0. Result The prevalence of gaming disorder was 8.5% among 260 internet gaming users. About 69.2% of the participants reported that their gaming behavior had increased due to stress of COVID-19 pandemic. Gender and spending more time online per day showed significant associations with greater scores on the internet gaming disorder. Conclusion During lockdown period of COVID-19 pandemic, the gaming behavior of medical college students has increased.

Prevalence of Nonalcoholic Fatty Liver Disease in a Tertiary Care Teaching Hospital: A Cross Sectional Study in Province 4 of Nepal.

Background Nonalcoholic fatty liver disease (NAFLD) is collection of lipids in hepatic tissues excluding other hepatic diseases and chronic alcohol intake. It may advance to nonalcoholic steatohepatitis or cirrhosis. Ultrasonography has high sensitivity and specificity for detecting nonalcoholic fatty liver disease. Objective Lack of sufficient information in this region on sonological prevalence of nonalcoholic fatty liver disease, lead us to design the survey and may also serve as reference for further researches. Method This is a cross sectional study with 600 participants, conducted at Gandaki Medical College Teaching Hospital, Province 4 of Nepal, from September to October 2017. Ethical approval is taken from the Institutional review board. The study group includes the participants referred for abdominal sonography from outpatient department. Result In present survey, 367 (61.2%) are female and 233 (38.8%) are male participants. The mean age is 41.6 years and median age is 38 years. The prevalence of nonalcoholic fatty liver in our observation is 229 cases (38.2%) of which, 102 cases (44.5%) are male and 127 cases (55.4%) are female participants. Normal liver was seen in 61.8%, Grade one fatty liver was discovered in 24.8%, Grade one in 12.6% and Grade three in 0.6%. The mean liver size in those with fatty liver was 14.1 cm. Conclusion Province 4 of Nepal is not exempt from the growing epidemic of nonalcoholic fatty liver disease with prevalence of 38.2%. The study shows that with higher grades of fatty liver, the size of liver is also increased and the mean age of the participants involved is also in the higher side of the spectrum.

Preoperative serum uric acid predicts incident acute kidney injury following cardiac surgery.

BACKGROUND: Acute kidney injury (AKI) following cardiac surgery is a frequent complication and several risk factors increasing its incidence have already been characterized. This study evaluates the influence of preoperative increased serum uric acid (SUA) levels in comparison with other known risk factors on the incidence of AKI following cardiac surgery. METHODS: During a period of 5 month, 247 patients underwent elective coronary artery bypass grafting, valve replacement/ repair or combined bypass and valve surgery. Datas were prospectively analyzed. Primary endpoint was the incidence of AKI as defined by the AKI criteria comparing patients with preoperative serum uric acid (SUA) levels below versus above the median. Multivariate logistic regression analysis was used to identify independent predictors of postoperative AKI. RESULTS: Thirty (12.1%) of the 247 patients developed postoperative AKI, 24 of 30 (80%) had preoperative SUA- levels above the median (≥373 µmol/l) (OR: 4.680, CI 95% 1.840; 11.904, p = 0.001). In the multivariate analysis SUA levels above the median (OR: 5.497, CI 95% 1.772; 17.054, p = 0.003), cardiopulmonary bypass (CPB) time > 90 min (OR: 4.595, CI 95% 1.587; 13.305, p = 0.005), cardiopulmonary bypass (CPB) > 30 kg/m2 (OR: 3.208, CI 95% 1.202; 8.562; p = 0.02), and preoperative elevated serum-creatinine levels (OR: 1.015, CI 95% 1.001; 1.029, p = 0.04) were independently associated with postoperative AKI. CONCLUSIONS: Serum uric acid is an independent risk marker for AKI after cardiac surgery. From all evaluated factors it showed the highest odds ratio.

Implementation research to assess a health workers performance-based management system in Nepal.

AIM: To test and refine a performance-based management system to improve health worker performance in Nepal. METHODS: A mixed-methods implementation research in three districts. The study assessed health workers' job satisfaction at the start and end of the study. Qualitative techniques were used to document processes, and routine health service data were analysed to measure outcomes. RESULTS: Job satisfaction significantly increased in six of nine key areas, and the proportion of staff absenteeism significantly declined in the study districts. It demonstrated an increase in immunisation coverage, the proportion of women who had a first antenatal check-up also having a fourth check-up and the proportion of childbirth in a health facility. The greatest perceived strengths of the system were its robust approach to performance planning and evaluation, supportive supervision, outcome-based job descriptions and a transparent reward system. A functional health facility environment, leadership and community engagement support successful implementation. CONCLUSION: The performance-based management system has the potential to increase health workers' job satisfaction, and it offers a tool to link facility-wide human resource management. A collaborative approach, ownership and commitment of the health system are critical to success. Considering the Nepal context, a management system that demonstrates a positive improvement has potential for improved health care delivery.

Bacterial isolates and its antibiotic susceptibility pattern in NICU.

BACKGROUND: Neonatal sepsis is one of the major causes of morbidity and mortality among the newborns in the developing world. OBJECTIVES: To determine the common bacterial isolates causing sepsis in neonatal intensive care unit and its antibiotic susceptibility pattern. METHODS: A one year discriptive prospective study was conducted in neonatal intensive care unit to analyse the results of blood culture and to look into the sensitivity of the commonly used antibiotics. RESULTS: The blood culture yield by conventional method was 44.13% with nosocomial sepsis accounting for 10.79%. 84.08% were culture proven early onset sepsis and 15.95% were late onset sepsis. Klebsiella infection was the commonest organism isolated in early, late and nosocomial sepsis but statistically not significant. Gram positive organisms were 39.36% in which Staphylococcus aureus was the leading microorganism followed by coagulase negative staphylococcus areus. Gram negative organisms were 60.64% amongst them Klebsiella was the most often encountered followed by Pseudomonas. The most common organism Klebsiella was 87.5% and 78.3% resistance to ampicillin and gentamycin respectively. Among gram negative isolates 87.5% and 77.2% were resistance to ampicillin and gentamycin respectively. Among gram positive isolates 58.5% and 31.5% resistance were noted to ampicillin and gentamycin respectively. Resistance to cefotaxim to gram negative and gram positive isolates were 87.34% and 59.35% respectively. CONCLUSION: Klebsiella is most common organism which is almost resistance to first line antibiotics. Resistance to both gram negative and gram positive isolates among firstline antibiotics and even with cefotaxim is emerging and is a major concern in neonatal intensive care unit.

Bruckner red light reflex test in a hospital setting.

BACKGROUND: Childhood blindness is a major problem in developing world including Nepal that needs to be addressed. OBJECTIVE: The objective of study was to measure the effectiveness of the Bruckner red reflex test for screening of posterior segment opacities in children. METHODS: Patients aged less than five years who came to the Tilganga Institute of Ophthalmology, Kathmandu from March to August, 2009 were recruited in this cross-sectional descriptive study. Children were screened with the Bruckner red light reflex test in a dark room. Patients with abnormal Bruckner tests had their eyes dilated for further investigations. Abnormalities were recorded. The number of patients with an abnormal Bruckner test was recorded and correlated with their potential pathology. RESULTS: A total of 172 patients with 97 boys and 75 girls were included. Twenty-three had abnormal Bruckner test results in either one or both eyes. Four of these twentythree patients had no pathology diagnosed; hence the sensitivity of the Bruckner screen to diagnose significant pathology was calculated at 82.6%. Of the 153 patients with normal results, two patients were found to have pathology detected, which included cataract and strabismus. Hence, the specificity of this test was 98.7%. The screening test had a positive predictive value of 90.5% and a negative predictive value of 97.4%. CONCLUSION: Bruckner test screening is a sensitive and specific marker for detecting the posterior segment opacities in children. We recommend utilizing the test to evaluate these problems where other technologies are rare.

Hypothermic circulatory arrest with "low flow" lower body perfusion: an experimental feasibility study of microcirculatory parameters.

BACKGROUND: To avoid extended cardiopulmonary bypass (CPB), moderate temperatures are commonly accepted for hypothermic circulatory arrest (HCA), thereby jeopardizing organ protection. Distal aortic perfusion may be an option, but supportive experimental data is missing. METHODS: Eight juvenile pigs (36 ± 2 kg) were cooled to 30 °C followed by 60 min of HCA with 50 min of low flow (LF) lower body perfusion. Multimodal monitoring was used to measure overall metabolism, hemodynamics and microcirculation of the terminal ileum. The animals were observed for four hours following reperfusion. Organs were harvested for histopathological evaluation. RESULTS: During LF perfusion, initially elevated l-lactate levels decreased subsequently ( P < 0.05). Capillary blood flow decreased during cooling to 50 % baseline levels ( P = 0.03), but remained stable under LF conditions. Parameters indicative of reduced liver and kidney function were slightly elevated at the end of the experiment, but still within normal ranges. CONCLUSION: Under moderate hypothermia, low flow perfusion seems to provide adequate protection for the lower body organs. Microcirculatory parameters during perfusion as well as lactate levels within normal ranges throughout the experiments further confirm the concept.

Age-related macular degeneration in Nepal.

BACKGROUND: The Age related Macular Degeneration (AMD) is a common cause of visual impairment and blindness worldwide in elderly. OBJECTIVE: This study aimed to explore the demographic characteristics, pattern and risk factors for AMD at a tertiary referral eye centre in Nepal. METHODS: This is a hospital-based prospective study, conducted at Tilganga Institute of Ophthalmology, Nepal from September 2008 to May 2009. All the consecutive cases of AMD diagnosed at the institute were included. RESULTS: A total of 141 patients (266 eyes) with AMD recruited for the study. The mean age was 69.5 years (9.1SD) with three fifth males (58.9%). Housewives and occupations like agriculture comprised of 38.3% and 42.5% respectively. Three fourth (75.6%) of the patients were illiterate. The proportion of dry and wet AMD were found in 62.4% and 37.6% respectively. Bilateral involvement was seen in 88.7% of the subjects. Three fourth (71.4%) of the AMD eyes had presenting visual acuity less than 6/18. History of smoking was found in 69.9% of patients. Hypertension was the predominant systemic problem (45.4%) followed by diabetes mellitus (12.8%). CONCLUSION: AMD is correlated with ageing in our study as well. Dry AMD is more in age groups 45-64 years and wet AMD at 65 years and older. Bilateral involvement with one eye dry and fellow eye wet AMD is more predominant (44%). Smoking and occupations like agriculture and housewife are significant risk factors for AMD. Likewise male sex, illiteracy and hypertension are other risk factors for AMD in hospital settings.

A case of precocious puberty in a setting with limited resources.

Precocious puberty is a rare condition characterized by the development of secondary sexual characteristics before the median age for the sex. It is either gonadotropin dependent also called as central or gonadotropin independent also known as peripheral type. Hypothalamamic Hamartoma is a common cause of the central or precocious puberty due to organic brain lesion. Here we present a two year male who presented us with precocious puberty due to a hypothalamic Hamartoma.

Flower colour and size signals differ depending on geographical location and altitude region.

Bees are major pollinators of angiosperms and have phylogenetically conserved colour vision but differ in how various key species use achromatic information that is vital for both flower detection and size processing. We modelled green contrast and colour contrast signals from flowers of different countries where there are well established differences in availability of model bee species along altitudinal gradients. We tested for consistency in visual signals as expected from generalization in pollination principles using phylogenetically informed linear models. Patterns of chromatic contrast, achromatic green contrast and flower size differed among the three floras we examined. In Nepal there is a significant positive correlation between flower size and colour contrast in the subalpine region, but a negative correlation at the lower altitudes. At high elevations in Norway, where pollinators other than bees are common, flower size was positively correlated with colour contrast. At low and medium altitudes in Norway and in Australia, we did not observe a significant relationship between size and colour contrast. We thus find that the relationship between size, green and colour contrast cannot be generalized across communities, thus suggesting that flower visual signal adaptations to local pollinators are not limited to chromatic contrast.

Treatment of acute aortic dissection type A (AADA): technical considerations.

Aortic dissection is one of the the most common and lethal catastrophes involving the aorta. Speedy diagnosis, as well as appropriate therapy are essential for survival of the patients. Because the clinical presentation in patients suffering AADA can differ substantially, discussion concerning specific surgical therapy remains controversial. This implies questions regarding the treatment of the aortic root as well as the aortic arch and the proximal descending aorta. The current manuscript raises important issues regarding surgical treatment of AADA patients which are discussed in the light of the institutional policy in the author's department.

An ultrasonographic evaluation of solitary muscular and soft tissue cysticercosis.

BACKGROUND: Cysticercosis in humans is infection with the larval form (cysticercus cellulosae) of the pork tapeworm T. solium. Encystment of larvae can occur in almost any tissue. The location of cysts in order of frequency is the central nervous system, subcutaneous tissue and striated muscle, vitreous humour of the eye and, rarely, other tissues. High resolution ultrasound can be used in the diagnosis of muscular and soft tissue cysticercosis. OBJECTIVE: The aim of this study is to evaluate the ultrasonographic findings in cases of muscular and soft tissue cysticercosis. MATERIALS AND METHODS: It was a retrospective review of the cases of muscular and soft tissue cysticercosis which were diagnosed by ultrasound during June 2007 to May 2009 in the department of Radiology and Imaging, Nepalgunj Medical College Teaching Hospital. A total of six patients were evaluated. RESULT: There were four males and two females. Age of the patient ranged from 18 to 50 years. All of the patients presented with a swelling with pain in fi ve of them. There was a wide variation in the location of the cysts. In all cases ultrasound revealed a cystic lesion with an echogenic eccentric pedunculated nodule attached to the wall. The mean diameter of the cyst was 6mm. Smooth wall was present in fi ve cases whereas one of the cysts revealed irregular wall. Pericystic inflammatory changes were seen in the adjacent muscles. CONCLUSION: Ultrasound is a safe and non-invasive method that can be used in the diagnosis of muscular and soft tissue cysticercosis.

Rewardlessness in orchids: how frequent and how rewardless?

About one-third of orchid species are thought to offer no floral reward and therefore attract pollinators through deception. Statements of this idea are common in the botanical literature, but the empirical basis of the estimate is rarely mentioned. We traced citation pathways for the one-third estimate in a sample of the literature and found that the paths lead to empirical foundations that are surprisingly narrow. Moreover, recent measurements have detected minute quantities of sugar available to insect visitors in some orchids thought to be rewardless, raising the possibility of a pollination strategy that is largely deceitful but different to absolute rewardlessness. The orchids are a well-studied group and there is no doubt that rewardlessness is common in the family. However, greater empirical effort is needed to verify rewardlessness in orchids and to explore geographic and environmental variation in the proportion of rewardless species.

Colour evolution within orchids depends on whether the pollinator is a bee or a fly.

Orchids are a classic angiosperm model for understanding biotic pollination. We studied orchid species within two species-rich herbaceous communities that are known to have either hymenopteran or dipteran insects as the dominant pollinators, in order to understand how flower colour relates to pollinator visual systems. We analysed features of the floral reflectance spectra that are significant to pollinator visual systems and used models of dipteran and hymenopteran colour vision to characterise the chromatic signals used by fly-pollinated and bee-pollinated orchid species. In contrast to bee-pollinated flowers, fly-pollinated flowers had distinctive points of rapid reflectance change at long wavelengths and a complete absence of such spectral features at short wavelengths. Fly-pollinated flowers also had significantly more restricted loci than bee-pollinated flowers in colour space models of fly and bee vision alike. Globally, bee-pollinated flowers are known to have distinctive, consistent colour signals. Our findings of different signals for fly pollination is consistent with pollinator-mediated selection on orchid species that results from the distinctive features of fly visual systems.

Outcome of pneumatic retinopexy at a tertiary eye care centre in Nepal.

BACKGROUND: Rhegmatogenous retinal detachment is one of the commonly encountered retinal problems where timely treatment could prevent irreversible vision loss. Pneumatic retinopexy (PR) is a simple and minimally invasive procedure for retinal reattachment. AIM: This study aimed to assess the outcome of pneumatic retinopexy in primary rhegmatogenous retinal detachment at our facility. STUDY DESIGN: This was a retrospective- prospective, interventional case series. MATERIALS AND METHODS: All subjects with rhegmatogenous retinal detachment who underwent pneumatic retinopexy at Tilganga Eye Centre of Nepal from January 2002 to June 2007 were included in this study. RESULTS: A total of 32 cases were included in the study. The mean age of patients was 55.2 year (SD=11.0). The majority of cases (62.5%) presented within two weeks of symptoms with blurring of vision in 90% of cases. Pre-operatively, 56.3% (18) patients had a best corrected distance visual acuity of <6/60. Retinal detachment involving less than two quadrants consisted of 37.5% (12). A single retinal break was present in 78.1% (25) of cases and 87.5% (28) of the retinal breaks were located in the superotemporal quadrant. The macula was attached in 37.5% (12) of the cases. Sulfurhexafluoride and Perfluoropropane were used in 68.8% (22) and 31.3% (10) respectively. The average follow up period was 1.02 years (range one month to four years). The retina was completely attached in 81.3% (26) of cases at the last follow up. The best corrected distance visual acuity of 6/18-6/60 was found in 40.6% (13) of subjects in the last follow up. There was a transient rise in intraocular pressure in 6.3% (2) of subjects after the procedure. CONCLUSION: The anatomical success rate following pneumatic retinopexy is quite high (81.3%) with good visual recovery and less morbidity translating to higher productivity for the patient. This procedure, being quicker than the alternatives, will also save surgeon's time making PR a good choice for managing primary rhegmatogenous retinal detachment in countries like Nepal where resources are scarce.

Abnormalities in Protocol Graft Kidney Biopsy 6 Months Posttransplantation in a Tertiary Care Center Hospital of Nepal.

BACKGROUND: Increasing graft survival is the prime focus of every transplantation program. Detection of subclinical abnormalities with the help of protocol renal graft biopsies performed at predetermined intervals after transplantation has been one of the approaches. The objective was to study the abnormalities in protocol renal graft biopsy specimens at 6 months posttransplantation. METHODS: This was a hospital-based observational descriptive study. It included the recipients who underwent kidney transplantation between October 2014 and September 2015. The recipients were followed up postoperatively on an outpatient basis, as per the institution protocol. At 6 months posttransplantation, protocol graft biopsy was performed in all patients with normal functioning allograft without proteinuria after obtaining informed written consent. RESULTS: A total of 57 patients with chronic kidney disease underwent renal transplantation during the study period. Protocol biopsy was performed in 47 recipients. Subclinical rejection was found in 4 (8.5%) recipients. Two recipients had significant tubulitis and interstitial inflammation. One of them showed features of Banff Type IA cellular rejection (t2, i2) and another showed Banff Type IB cellular rejection (t3, i2). Biopsy specimen of 1 recipient showed significant glomerulitis and peritubular capillaritis (g3, ptc1). Another recipient showed significant peritubular capillaritis (ptc2) with C4d positivity. IgA nephropathy was present in 6 (12.8%) recipients. BK virus nephropathy was found in 2 (4.3%) recipients. CONCLUSION: This study demonstrates that abnormal histologic findings occur in protocol graft biopsy specimens at 6 months post renal transplantation in patients without any clinical or laboratory abnormalities.

Spectrum of Infections in Living Donor Kidney Transplant Recipients: An Experience From a Tertiary Center in Nepal.

BACKGROUND: Kidney transplant recipients are always at risk of infections because they are on lifelong immunosuppressive medications. The spectrum of infections in this special population is not the same as in the general population. Post-transplant infections are extensively studied in the developed world. Publications about post-transplant infections from Nepal are scarce. This study was carried out to study the spectrum of infections, the trends in treatment, and the incidence of tuberculosis in kidney transplant recipients. METHODS: This is a retrospective analysis of the patient data in Tribhuvan University Teaching Hospital, Kathmandu, Nepal. Follow-up data from the first 100 kidney transplant recipients was recorded in a Microsoft Excel worksheet and descriptive analysis was done. RESULTS: In the first 100 transplants done until 21 September 2011, 92 patients' data were recorded and 8 patients' data were missing. The mean follow-up period was 61.03 months. The population was 76.09% male (n = 70) and 23.91% female (n = 22). A total of 641 episodes of infections were recorded. Urinary tract infections were the most common type of infection. Escherichia coli was the most common organism isolated (36% of all cultures). There were 17 (2.65%) episodes of viral and 42 (6.6%) episodes of fungal infections. Tuberculosis was diagnosed in 6 (6.5%) patients. CONCLUSION: Urinary tract infection is the most common type of infection in post-kidney transplant patients. Quinolones were the most common agents used to treat urinary tract infections. The incidence of tuberculosis in kidney transplant recipients is 6.5% in 5 years' follow-up.
