RESUMO
Dual antiplatelet treatment (DAPT) is the cornerstone of the management and prophylaxis of acute coronary syndrome (ACS). However, the associated risk of bleeding with the usage of DAPT and risk of thrombosis with stoppage of the drug makes it a challenging task to take appropriate decisions regarding the choice and duration of DAPT. The present study is aimed to tackle these challenges and to analyze whether prolonged dual antiplatelet therapy carries more risk of bleeding or a higher risk of thrombosis is present with discontinuation of the same. MATERIAL: In this study, a total of 235 cases of confirmed myocardial infarction, unstable angina, or those who underwent percutaneous intervention were included. After 1 year, the number of patients on DAPT, the type of antiplatelets they were using were observed, their ischemic risk was calculated using DAPT score, and bleeding risk was calculated using PRECISE-DAPT score. Bleeding events were assessed using BARC classification. OBSERVATION: Out of 235 patients, the majority of the patients were males (78.7%). Only 7.2% of the patients had bleeding since the start of the drugs. The majority (5% out of 7.2%) of bleeding episodes were clinically insignificant. 163 (69%) patients were on Dual antiplatelet therapy after 1 year. Out of which 115 were appropriately taking DAPT as per their DAPT score. Patients with high bleeding risk (PRECISE DAPT score ≥25) were 89, out of which 38 (53.2%) patients were taking SAPT, appropriate for their bleeding risk. While 112 (68.7%) were taking prolonged DAPT, appropriate for PRECISE-DAPT risk. CONCLUSION: The majority of patients remained on DAPT following discharge for more than 1 year after ACS. This suggests that treating physicians prioritizes ischemic risk reduction over bleeding risk in patients with ACS, according to the patient's risk profile.

Background Clinical microscopists are at a greater risk of developing binocular vision anomalies and asthenopia. Objective To assess the refractive and binocular vision status and to explore the association between the presence of asthenopic symptoms and microscopy work among clinical microscopists working at medical laboratory department. Method This cross-sectional study involved 37 clinical microscopists working at medical laboratory department of Dhulikhel Hospital, Nepal. The study was conducted from January to December 2013. Only those participants who had been using microscope for at least a year were enrolled in this study. Each participant underwent distance visual acuity (VA) assessment, refractions, and orthoptic evaluation, including measurement of distance and near phoria, near point of convergence (NPC), near point of accommodation (NPA), positive fusional vergence (PFV), adduction, and calculation of accommodation convergence/accommodation (AC/A) ratio. The tear test was also carried out in each subject. Information about use of glasses, microscopy work (duration, and time spent per day in microscope), and visual symptoms associated with the use of microscope such as eye strain, headache, double vision, and near vision were collected. Result The mean age of the clinical microscopists was 29 ± 5.7 years. The prevalence of refractive error was 56.76% and the mean spherical equivalent (SE) refractive error was -0.77 ± 0.86 D. Refractive error had neither correlation with microscopy work and asthenopic symptoms associated with it, and nor with binocular vision parametersNPC, AA and AC/A ratio. However, there was a positive association between asthenopic symptoms and microscopy work. There was statistically significant difference between symptomatic and asymptomatic subjects for binocular vision parameters, including NPC, AA and positive fusional vergence (PFV) for near. Conclusion Microscopy work has an impact on near binocular vision. Asthenopic symptoms bear a positive association with microscopy work. Refractive error has no significant correlation with either microscopy works or associated asthenopic symptoms.

Background There are different methods to repair the perforation of the tympanic membrane. Recently cartilage has been used for the repair and results are comparable to temporalis fascia. For surgical procedure endoscope had added good assistance in middle ear surgery. Though the one hand technique the image quality and results are on par with the use of a microscope. Objective To compare the graft uptake rate and hearing results between temporalis fascia and tragal cartilage in endoscopic myringoplasty. Method This is a prospective, longitudinal study conducted among 50 patients who underwent endoscopic myringoplasty using temporalis fascia and tragal cartilage with 25 patients in each group. The hearing was assessed by comparing pre with post-operative ABG (Air bone gap) and ABG closure in speech frequencies (500Hz, 1 KHz, 2 KHz, 4 KHz). The status of graft and hearing results was evaluated on 6 months of follow up in both the groups. Result Out of total 25 patients enrolled for study in both (temporalis fascia and cartilage) groups, 23 (92%) patients in each group had graft uptaken. The audiological gain in the temporalis fascia group was 11.37±0.32 dB whereas in the tragal cartilage group it was 14.56±1.22dB. The audiological gain between the two groups did not show any statistically significant (p = 0.765). However, the pre and post-operative hearing difference was statistically significant in both temporalis fascia and tragal cartilage group. Conclusion Tragal cartilage has similar graft uptake rate and hearing gain when compared with temporalis fascia in endoscopic myringoplasty. Hence, tragal cartilage can be used for myringoplasty whenever required without any fear of deterioration in hearing.

Nearly a century ago it was recognized that radiation absorption by stellar matter controls the internal temperature profiles within stars. Laboratory opacity measurements, however, have never been performed at stellar interior conditions, introducing uncertainties in stellar models. A particular problem arose when refined photosphere spectral analysis led to reductions of 30-50 per cent in the inferred amounts of carbon, nitrogen and oxygen in the Sun. Standard solar models using the revised element abundances disagree with helioseismic observations that determine the internal solar structure using acoustic oscillations. This could be resolved if the true mean opacity for the solar interior matter were roughly 15 per cent higher than predicted, because increased opacity compensates for the decreased element abundances. Iron accounts for a quarter of the total opacity at the solar radiation/convection zone boundary. Here we report measurements of wavelength-resolved iron opacity at electron temperatures of 1.9-2.3 million kelvin and electron densities of (0.7-4.0) × 10(22) per cubic centimetre, conditions very similar to those in the solar region that affects the discrepancy the most: the radiation/convection zone boundary. The measured wavelength-dependent opacity is 30-400 per cent higher than predicted. This represents roughly half the change in the mean opacity needed to resolve the solar discrepancy, even though iron is only one of many elements that contribute to opacity.
RESUMO
Background Corneal blindness accounts for a significant proportion of avoidable visual impairment in developing countries. Eye donation is voluntary and awareness in undergraduate medical students being a future practitioner in any field are expected to be linked to patients during death in hospitals. Objective To assess the awareness of medical students on eye donation at Kathmandu University School of Medical Sciences (KUSMS). Method This was a cross-sectional study conducted among undergraduate medical students of KUSMS. Students' responses were recorded using a predesigned, pretested, semistructured questionnaire inquiring knowledge and attitude of eye donation, sources of information, their willingness to donate eyes as well as the reasons for donating/ not donating eyes. Result Less than half of the medical students (45.6%) were aware of eye donation only after death. Newspapers (72.2%) were the major source of information. The final year medical students were more aware (Average knowledge score = 11.56 ± 2.05) than their juniors. 80.7% of the students were willing to donate their eyes. The adjudged reasons for willingness to donate were that eye donation is a noble work and pleasure in helping a blind person while the reasons for unwillingness to donate were lack of awareness followed by family objection to eye donation. Conclusion Future medical practitioners possessed satisfactory knowledge about eye donation. Educating this cadre of human resources to sensitize them towards the need for eye donation would be a crucial step towards reducing the global burden of corneal blindness.

Background Hearing loss among neonates is one of the important health issue in pediatric population which may remain unnoticed until the child reaches a certain age. The importance of universal early screening, diagnosis and intervention in reducing the negative impact of congenital hearing loss has been described all over the world. Objective To observe the outcome of hearing screening by Automated Auditory Brainstem Response (AABR) in newborns delivered in Dhulikhel Hospital and neonates admitted in an intensive care unit (NICU) of Dhulikhel Hospital. Method A prospective study was done in neonates who were born at Dhulikhel Hospital, Kathmandu University Hospital from February 15th, 2017 to October 30th, 2019. AABR was used for their hearing assessment within 24 hours of birth and again at about 6 weeks of age in those neonates who failed the initial test. All the neonates admitted in NICU were studied regarding the risk factors based on Joint committee on Infant Hearing. Those who failed the test for the second time were referred for detailed audiological diagnostic work up. Result The screening rate was 92.6% of the total deliveries. A total of 5517 neonates comprising of 2800 males and 2717 females were screened from total deliveries of 5956 neonates in the study period. Among them, NICU (sick) babies were 422 (7.7%) and well babies were 5095 (92.3%). Out of them, 1675 failed the test in the first screening and 374 failed in the second screening. So, the total number of referred babies in second screening was 6.7% (374) out of 5517 screened. Amongst them, well babies were 6.59% (336), out of 5095 screened and sick babies were 9% (38) out of 422 screened. Low birth weight and prematurity were found to be the commonest risk factor present among them, followed by the use of ototoxic medications, hyperbilirubinemia and prolonged use of mechanical ventilation. Conclusion Automated Auditory Brainstem Response (AABR) is a very useful tool for hearing screening which should preferably be done in all the neonates where possible. It should be done within one month of life and those with confirmed hearing loss should receive early appropriate intervention for better hearing in future.

Background Presence of recanalisation will favour for better physiological recovery after medical management of Deep Vein Thrombosis (DVT) along with lesser chances of post thrombotic syndrome. Rate of recanalisation is varied and can range from 43-57% and the factors that affect recanalisation are still a dilemma. Objective To know the factors for recanalisation following Deep Vein Thrombosis. Method This is a single institution based retrospective-prospective analytical study encompassing all ultrasonologically diagnosed cases of Deep Vein Thrombosis in adults from January 2015 to November 2017. All the cases were admitted with oral warfarin bridged by Heparin/ Enoxaparin and were discharged once International Normalization Ratio was in therapeutic range. The patients were followed up for three months with minimal of three outpatient followup. Best finding in the doppler ultrasonography (done by Acuson P500, Seimens) in relation to recanalisation was taken for the study. Result There were 67 cases of Deep Vein Thrombosis. Of these cases male to female ratio was 0.91. The mean age was 48.07. Most common extent was up to common femoral vein (47.8%) followed by upto popliteal vein (40.3%). Remaining 11.9% had extension upto iliac veins. There was no recanalisation in 2 cases (3%). Partial recanalisation was seen in 23 cases (34.3%) while complete recanalisation was seen in 42 cases (62.7%). Recanalisation is more in DVT involving popliteal vein while it decreases as the extension goes up. In contrast to 79.4% complete recanalisation in popliteal vein, that in common femoral vein is 62.5% while in iliac vein is only 37.5%. Mean age in no recanalisation group is much younger than partial or complete recanalisation groups. Conclusion Recanalisation following Deep Vein Thrombosis distal to popliteal vein is more than that in proximal Deep Vein Thrombosis. The information on recanalization can be considered to use to decide upon the duration of medical management of Deep Vein Thrombosis.

Background Uncorrected refractive error is one of the most important causes of visual impairment worldwide. Objective To ascertain the pattern and prevalence of refractive error and secondary visual impairment in subjects attending Ophthalmology department. Method A prospective hospital-based study was designed where presenting visual acuity, age of presentation, refractive status, best corrected visual acuity and status of visual impairment were assessed in participants, ages ranging from 3-39 years presenting to the Ophthalmology department of Dhulikhel Hospital, Kathmandu University Hospital. History of use of spectacle was noted and participants were categorized into different visual impairment categories as per their presenting visual acuity. Result Out of a total of 4500 total clients examined during the study period, 388 (8.62%) had refractive error where 219 (56.44%) were females and 169 (43.56%) were males. Mean age at presentation was 22.70±7.69 years (range, 3-39 years). Astigmatism was the most common subtype seen in 373 eyes (48.06%), followed by myopia (366 eyes, 47.16%) and hypermetropia (31 eyes, 4.0%). Only 40.50% subjects who required refractive correction were using spectacle. 62.37% (242 clients) had some of visual impairment during their presentation. There was statistically significant improvement in visual acuity after refractive correction (p=0.00). Conclusion Uncorrected refractive error is one of the most important causes of visual impairment. Lack of awareness, infrequent ocular examination and lack of community or preschool vision screening were the main causes for the late presentation and significant visual impairment associated with the condition. Social stigma, economical limitation and negative counseling and attitudes about spectacle wear were primary factors behind the unsatisfactory spectacle use.

INTRODUCTION AND HYPOTHESIS: The objective was to assess the feedback from a quality improvement training programme to reduce obstetric anal sphincter injuries (OASIS). METHODS: Training sessions were organised that included evidence-based information on OASIS risk factors and training on models to measure perineal body length (PBL), perform episiotomies with standard and 60° fixed angle scissors (EPISCISSORS-60®), and measure post-delivery episiotomy suture angles with protractor transparencies. Feedback forms using a Likert scale (1-4) were completed and analysed. The setting was an evidence-based quality improvement programme (Strategy for Using Practical aids for Prevention of OASIS, Recording episiotomies and clinician Training [SUPPORT]) at two National Health Service (NHS) Hospitals in the UK. The participants were midwives and doctors attending the SUPPORT training programme RESULTS: All of the participants (100 %) would recommend the training programme to a friend or colleague. 92 % felt that the training session improved their knowledge of the impact of PBL and perineal distension and their knowledge of the relationship between episiotomy angle and OASIS "a lot" or "somewhat". CONCLUSION: Based on this feedback, we recommend the addition of the knowledge content of the SUPPORT programme to other centres providing perineal assessment and repair courses.

Background The endoscopes have better optics and magnification with wide angle of view due to angled lenses. It provides the excellent resolution of image in surgeries having many difficult anatomic nooks and corners like; antero-inferior recess of external auditory canal, middle ear cavity and difficult areas to visualize under microspore like sinus tympani. Likewise, the use of cartilage has very low metabolic rate, provide support to prevent retraction and reacts minimally to inflammatory reaction, so it has advantageous role in closure of tympanic membrane perforations. Objective The main objective of our study is to see the graft uptake rate and hearing results after endoscopic cartilage myringoplasty with our own modification. Method This is a prospective, cohort study conducted among 37 patients who underwent endoscopic modified inlay butterfly cartilage perichondrium myringoplasty using tragal cartilage. The hearing was assessed by comparing pre with post-operative ABG (Air bone gap) and ABG closure in speech frequencies (500Hz, 1KHz, 2KHz, 4KHz). Result Among 42 patients, 37 (88.09%) had graft uptaken. Other five patients had residual perforation because of infection. The post-operative ABG was smaller than pre-operative ABG.(26.41±8.47dB and 36.57±12.13dB respectively). The mean ABG closure was 10.15±10.23dB. The ABG closure was ≤ 10dB in 28(75.6%) patients. Conclusion Endoscopic modified inlay butterfly cartilage perichondrium myringoplasty has advantages in terms of hearing results and graft uptake rate as it is comparable or even better than others. So, it is advisable to perform this technique without any difficulty.

Longitudinal data from 3 commercial dairy herds in the northeast United States, collected from 2004 to 2011, were analyzed to determine the effect of Mycobacterium avium ssp. paratuberculosis (MAP) infection status and progression path on milk production. Disease status, as indicated by MAP test results, was determined through quarterly ELISA serum testing, biannual fecal culture, and culture of tissues and feces at slaughter. Milk production data were collected from the Dairy Herd Information Association. Animals with positive MAP test results were categorized, based on test results over the full course of the study, as high path (at least one high-positive culture) or low path (at least one positive culture or ELISA). The cumulative numbers of positive ELISA and culture results were recorded. The effects of both MAP infection path, status, and number of positive tests on milk production were analyzed using a mixed linear model with an autocorrelation random effect structure. Low- and high-path animals produced more milk before their first positive test than always-negative animals, especially high-path animals. Although mean production decreased after a first positive test, low-path animals were shown to recover some productivity. High-path animals continued to exhibit a decrease in milk production, especially after their first high-positive fecal culture. These results show that not all animals that test positive for MAP will have long-term production losses. Milk production decreased significantly with each additional positive test. Ultimately, production loss appeared to be a function of MAP infection progression.

Background Ultrasonography is one of the most common imaging modality to measure dimensions of visceral organs in children. However, the normal limit of size of visceral organs according to age and body habitus has not been specified in the standard textbooks. This might result in under detection of organomegaly in pediatrics population. Objective The objective of this study was to determine the normal range of dimensions for the liver, spleen, and kidney in healthy children. Method This is prospective cross-sectional, hospital-based study done at Tertiary-care teaching hospital. Participants included 272 pediatric subjects (152 male and 120 female) with normal physical or sonographic findings who were examined because of problems unrelated to the measured organs. The subjects were one month to 15 year (180 months) old. All measured organs were sonographically normal. Relationships of the dimensions of these organs with sex, age, body weight and height were investigated. Limits of normal dimensions of these organs were defined. Result Normal length of liver, kidneys and spleen were obtained sonographically for 272 children (152 male [55.9%] and 120 female [44.1%]) in the age group from 1 months to 15 (180 months) years. The mean age was 45.78 months (SD, 44.73). The measured dimensions of all these organs showed highest correlation with height and age so the descriptive analysis of the organ dimensions (mean, minimum, and maximum values, SD and 5th and 95th percentiles) were expressed in 10 age groups along with height range of the included children. The mean length of right kidney was shorter than the left kidney length, and the difference was statistically significant (p = 0.001). Conclusion This study provides practical and comprehensive guide to the normal visceral organ dimension in pediatric population. The normal range limit of the liver, spleen, and kidney determined in this study could be used as a reference in daily practice in local radiology clinics.

Quantitative fluorescence spectroscopic Mueller matrix measurements from the connective tissue regions of human cervical tissue reveal intriguing fluorescence diattenuation and polarizance effects. Interestingly, the estimated fluorescence linear diattenuation and polarizance parameters were considerably reduced in the precancerous tissues as compared to the normal ones. These polarimetry effects of the autofluorescence were found to originate from anisotropically organized collagen molecular structures present in the connective tissues. Consequently, the reduction of the magnitude of these polarimetric parameters at higher grades of precancer was attributed to the loss of anisotropic organization of collagen, which was also confirmed by control experiments. These results indicate that fluorescence spectral diattenuation and polarizance parameters may serve as potentially useful diagnostic metrics.

External cephalic version (ECV) has been recognised by the Royal college of Obstetricians and Gynaecologists (RCOG) as a safe procedure for the conversion of breech presentations to cephalic presentation. The need to reduce the incidence of breech presentations is due to the associated increase in complications for both mother and baby in a breech delivery. The RCOG published the Green-top Guideline No. 20a in December 2006 and revised it in December 2010. In our study, we conducted a survey across all hospitals in the East of England (EoE) region in 2007 and 2012 to assess the ECV service and to determine if this fulfils the RCOG recommendations.

Heart failure (HF) is a condition with growing morbidity and mortality. Dyslipidemia in HF is not concentrated around hypercholesterolemia as in coronary artery disease. As a corollary, the robust benefits seen with statins across the spectrum of CAD have not been replicated in HF. Multiple potential pleiotropic effects of statins include anti-inflammatory, antioxidant, endothelial stabilization, antiapoptotic, anti-thrombotic, and modulation of the autonomic system apart from lipid lowering. These benevolent actions need to be counterbalanced with the potential derangement of ubiquinone, selenoprotein and endotoxin pathways. While small randomized and non-randomized studies demonstrated a multitude of benefits in clinical and surrogate endpoints, two large RCTs failed to demonstrate unequivocal benefits. However, multiple large meta-analyses do demonstrate definite improvement in clinical endpoints including death and heart failure hospitalization. The clinical likelihood of benefit was higher in younger patients with less advanced HF and use of lipophilic statins.

OBJECTIVE: To report the numbers of patients having childbirth after pelvic floor surgery in England. DESIGN: Retrospective analysis of Hospital Episode Statistics data. SETTING: Hospital Episode Statistics database. POPULATION: Women, aged 20-44 years, undergoing childbirth after pelvic floor surgery between the years 2002 and 2008. METHODS: Analysis of the Hospital Episode Statistics database using Office of Population, Censuses and Surveys: Classification of Interventions and Procedures, 4th Revision (OPCS-4) code at the four-character level for pelvic floor surgery and delivery, in women aged 20-44 years, between the years 2002 and 2008. MAIN OUTCOME MEASURES: Numbers of women having delivery episodes after previous pelvic floor surgery, and numbers having further pelvic floor surgery after delivery. RESULTS: Six hundred and three women had a delivery episode after previous pelvic floor surgery in the time period 2002-2008. In this group of 603 women, 42 had a further pelvic floor surgery episode following delivery in the same time period. The incidence of repeat surgery episode following delivery was higher in the group delivered vaginally than in those delivered by caesarean (13.6 versus 4.4%; odds ratio, 3.38; 95% confidence interval, 1.87-6.10). CONCLUSIONS: There were 603 women having childbirth after pelvic floor surgery in the time period 2002-2008. The incidence of further pelvic floor surgery after childbirth was lower after caesarean delivery than after vaginal delivery, and this may indicate a protective effect of abdominal delivery.

Self-assembled nanostructures of CulnGaSe2 (CIGS) comprising of nanosheets with sheet thickness of 20 nm have been developed via one-step electrochemically alloying technique. These self-assembled nanoplates exhibit highly intersecting behavior and transform from CuSe to CIGS as the reduction potential was varied. The morphological analysis indicated that the process resulted in a progression of crystallites to a series of heavy dense intersecting nanoplates. Further analyses revealed that the nanostructures keep their integrity on heat treatment. The structure confirms the inclusion of Indium and Gallium at higher reduction potentials and its transition from pseudoamorphous to polycrystalline structure. A strong correlation between reduction potential, and the composition was established. The spectroscopic and optical spectra clearly prove that the direct band gap for the as-grown and annealed thin films, and appropriate for solar cell applications. These self-assembled dense interweaved nanoplates structure have not been observed previously in CIGS semiconductor system and have potential implications forenergy applications.

PURPOSE: Recent meta-analyses have shown reduced re-rupture rates for the surgical management of Achilles ruptures. However, percutaneous repair has been demonstrated to lead to improved function and patient satisfaction but greater complications than open repair. In the current economic climate, it is reasonable to consider the financial cost of rupture management for both the patient and the provider. The cost-effectiveness of operative treatment of ruptures of the Achilles tendon was determined based upon theatre occupancy, clinic attendance and cast changes, operative complications and functional assessment score. METHODS: The cost-effectiveness of the surgical management of Achilles tendon ruptures between 2005 and 2011 in our unit was audited by comparing 49 patients receiving percutaneous repair to 35 patients whom had open repairs. RESULTS: There was no significant difference in complications between the two surgical techniques: (Open vs. Percutaneous) overall rates 14.3 versus 10.4 %: infection; 2.7 versus 2.0 %, transient sural nerve damage: 5.6 versus 8.1 %, wound breakdown: 2.8 versus 0.0 %, re-rupture: 2.8 versus 2.0 %. Achilles Total Rupture Scores (ATRS) were comparable [Open 89 (65-100) at 49 months vs. Percutaneous 88.8 (33-100) at 12 months (n.s.)]. Theatre occupancy (P < 0.00) and hospital stay (P < 0.00) were significantly longer with open repair [43 min (26-70) and 2.9 days (0-4)] compared to percutaneous repair [15 min (12-43) and 1.2 days (0-2)]. Excluding the costs of running the operating theatre, we have estimated the costs of surgery for open repair to be £ 935 and percutaneous repair to be £ 574. CONCLUSIONS: This study suggests that percutaneous repair of the Achilles tendon resulted in reduced costs and yet had comparable outcome and complications rates to open repair in surgical management of the Achilles tendon. Percutaneous repair should be considered as the primary method of cost-effective surgical management of Achilles tendon rupture.

The ageing population of the UK means that demand for urogynaecology services is expected to increase substantially, particularly in patients aged over 65 years. To assess service provision and predict future needs, we reviewed the demographic profile and service requirements of elderly patients referred to our urogynaecology service. We performed a retrospective review of case notes of 125 patients over 65 years of age who attended our urogynaecology clinic within a 6 month period, including comorbidity scoring using a validated instrument. A substantial proportion (56%) of patients did not require hospital-based management, and none of the patients had an adult comorbidity evaluation (ACE-27) score >2. Hence, we recommend assessing patients using the ACE-27 score and not on chronological age alone. A restructuring of urogynaecology services towards better access to community-based clinics is required to reflect the treatment needs of the patient population. This would be in line with national continence care guidance.
