[PMID: 38205143 PMCID: PMC10777759 DOI: 10.1177/2050313x231225348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Accepted: 12/19/2023] [Indexed: 01/12/2024] Open
Abstract
Acute pancreatitis is an acute inflammation of the pancreas, with subsequent involvement of surrounding tissues and organ systems. Viral etiology of acute pancreatitis is uncommon; however, multiple viruses have been implicated. Dengue virus has also been found responsible for acute pancreatitis, with possible etiologies linked to direct viral invasion, autoimmune mechanism, or as a complication of dengue shock syndrome. We present a case of a 24-year-old female who presented with epigastric pain and vomiting in the background of a febrile illness and was later diagnosed with mild acute pancreatitis complicating dengue fever.

Effects of acetate, propionate, and pH on volatile fatty acid thermodynamics in continuous cultures of ruminal contents. J Dairy Sci 2022; 105:8879-8897. [PMID: 36085109 DOI: 10.3168/jds.2022-22084] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 06/09/2022] [Indexed: 11/19/2022]
Abstract
To investigate the effects of acetate, propionate, and pH on thermodynamics of volatile fatty acids (VFA) in the rumen, a dual-flow continuous culture study was conducted to quantify production of major VFA, interconversions among the VFA, and H2 and CH4 emissions in a 4 × 4 Latin square design. The 4 treatments were (1) control: pH buffered to an average of 6.75; (2) control plus 20 mmol/d of infused acetate (InfAc); (3) control plus 7 mmol/d of infused propionate (InfPr); and (4) a 0.5-unit decline in pH elicited by adjustment of the buffer (LowpH). All fermentors were fed 40 g of a pelleted diet containing whole alfalfa pellets and concentrate mix pellets (50:50) once daily. After 7 d of treatment, sequential, continuous infusions of [2-13C] sodium acetate (3.5 mmol/d), [U-13C] sodium propionate (2.9 mmol/d), and [1-13C] sodium butyrate (0.22 mmol/d) were carried out from 12 h before feeding for 36 h. Filtered liquid effluent (4 mL) was sampled at 0, 2, 4, 6, 8, 12, 16, and 22 h after feeding, and assessed for VFA concentrations, with another filtered sample (20 mL) used to quantify aqueous concentrations of CH4 and H2. Headspace CH4 and H2 gases were monitored continuously. Ruminal microbes were isolated from the mixed effluent samples, and the microbial community structure was analyzed using the 16S rRNA amplicon sequencing technique. The digestibility of neutral detergent fiber, acid detergent fiber, and starch and microbial C sequestrated from VFA were not affected by treatments. The LowpH treatment increased net propionate production and decreased H2 and CH4 headspace emissions, primarily due to shifts in metabolic pathways of VFA formation, likely due to the observed changes in bacterial community structure. Significant interconversions occurred between acetate and butyrate, whereas interconversions of other VFA with propionate were relatively small. The InfAc and InfPr treatments increased net acetate and propionate production, respectively; however, interconversions among VFA were not affected by pH, acetate, or propionate treatments, suggesting that thermodynamics might not be a primary influencer of metabolic pathways used for VFA formation.

Possible unconventional order parameter in single crystals of SrPt 3P superconductor. JOURNAL OF PHYSICS. CONDENSED MATTER : AN INSTITUTE OF PHYSICS JOURNAL 2022; 34:435601. [PMID: 36040209 DOI: 10.1088/1361-648x/ac8a36] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 08/16/2022] [Indexed: 06/15/2023]
Abstract
Anisotropic properties of single crystals of SrPt3P were studied using London penetration depth and electrical resistivity measurements. The upper critical field,Hc2(T), was determined from four-probe electrical resistivity measurements for three orthogonal directions of a magnetic field with respect to the crystal. The London penetration depth,λ(T), was determined from the magnetic susceptibility of the Meissner-London state measured using a tunnel-diode resonator technique. WhereasHc2(T)and the normal-stateρ(T)are practically identical for all three magnetic field orientations, the London penetration depth shows significant unidirectional anisotropy. The low-temperatureλ(T)is exponentially attenuated when a small excitation radiofrequency magnetic field,Hrf, is applied along thec''-direction, in which case screening currents flow in thea''b''-plane, while for the other two orientations,Hrf∥a''andHrf∥b'', the London penetration depth shows a much stronger,λ(T)∼T2, variation. Such unusual and contrasting behavior of the two anisotropies,γHT=Hc2,ab/Hc2,c=ξab/ξcandγλT=λc/λab, imposes significant constraints on the possible order parameter. Although our measurements are insufficient to derive conclusively the superconducting gap anisotropy, the order parameter with two point nodes and a modulation in the perpendicular direction is qualitatively consistent with the experimental observations.

Targeting Macroautophagy as a Therapeutic Opportunity to Treat Parkinson's Disease. Front Cell Dev Biol 2022; 10:921314. [PMID: 35874822 PMCID: PMC9298504 DOI: 10.3389/fcell.2022.921314] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Accepted: 06/13/2022] [Indexed: 12/18/2022] Open
Abstract
Macroautophagy, an evolutionary conserved catabolic process in the eukaryotic cell, regulates cellular homeostasis and plays a decisive role in self-engulfing proteins, protein aggregates, dysfunctional or damaged organelles, and invading pathogens. Growing evidence from in vivo and in vitro models shows that autophagy dysfunction plays decisive role in the pathogenesis of various neurodegenerative diseases, including Parkinson's disease (PD). PD is an incurable and second most common neurodegenerative disease characterised by neurological and motor dysfunction accompanied of non-motor symptoms that can also reduce the life quality of patients. Despite the investment in research, the aetiology of the disease is still unknown and the therapies available are aimed mostly at ameliorating motor symptoms. Hence, therapeutics regulating the autophagy pathway might play an important role controlling the disease progression, reducing neuronal loss and even ameliorating non-motor symptoms. In this review, we highlight potential therapeutic opportunities involved in different targeting options like an initiation of autophagy, Leucine-rich repeat kinase 2 (LRRK2) inhibition, mitophagy, lysosomes, lipid metabolism, immune system, gene expression, biomarkers, and also non-pharmacological interventions. Thus, strategies to identify therapeutics targeting the pathways modulating autophagy might hold a future for therapy development against PD.

Cervical cancer screening utilization, and associated factors, in Nepal: a systematic review and meta-analysis. Public Health 2022; 210:16-25. [PMID: 35863158 DOI: 10.1016/j.puhe.2022.06.007] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 05/23/2022] [Accepted: 06/11/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To systematically appraise the existing published literature on cervical cancer screening utilization, and associated barriers and facilitators, in Nepal. STUDY DESIGN Systematic literature review and meta-analysis. METHODS PubMed/MEDLINE, CINAHL, Scopus, Embase, and, Google Scholar were systematically searched using Preferred Reporting Items for Systematic Review and Meta-Analysis guideline. All quantitative and qualitative studies reporting cervical cancer screening (using the Pap smear test or visual inspection with acetic acid or human papillomavirus test) utilization, barriers, and facilitators for screening were identified. A meta-analysis was performed to estimate Nepal's pooled cervical cancer screening utilization proportion. RESULTS The search yielded 97 records, of which 17 studies were included. Fifteen studies were quantitative and two were qualitative. Of the 17 studies, six were hospital-based and six were community-based. The pooled cervical cancer screening utilization proportion (using Pap smear test) among Nepalese women was 17% from the studies in the hospital settings, and 16% in the community. Six studies reported barriers to cervical cancer screening, of which four reported embarrassments related to the gynecological examination and a low level of knowledge on cervical cancer. Three (of four) studies reported health personnel, and two studies reported screening services-related facilitators for cervical cancer screening. CONCLUSION Our review reported that cervical cancer screening utilization (16%) is more than four times lower than the national target (70%) in Nepal. Multiple barriers such as low levels of knowledge and embarrassment are associated with cervical cancer screening utilization. Health personnel's gender, counseling, and privacy of screening services were commonly reported facilitators. These findings could help to inform future research, and policy efforts to increase cervical cancer screening utilization in Nepal.

Abstract
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.

Abstract
Background Second trimester abortions account for a small percentage of abortions globally. Abortion is one of the safest medical procedures. Accessibility of safe and high quality second-trimester abortion care can decrease severe complications associated with it. Objective The profile of women undergoing second-trimester abortion was assessed during the study. The profile includes demographic and clinical aspects. The study also aims to find out the rate of surgical and medical methods of abortion and to understand its indications. Method It is a study based on retrospective data collected from charts available at the comprehensive abortion care center at the Paropakar Maternity and Women's Hospital. The data from Shrawan to Magh 2077 B.S. was collected and calculations were done on MS Excel. Result Higher proportion of women receiving second-trimester abortion were of the age between 21-25 years (n=31; 31%). Most women were literate (n=69; 69%) and n=38(38%) were nulliparous. The most common indication for abortion was maternal mental issues (n=32; 32%). The rate of medical abortion was higher (n=71; 71%) than surgical method of abortion (n=29; 29%). Conclusion There exists both demographic and clinical variations in women undergoing secondtrimester abortion. Though few women undergo second trimester abortion than first-trimester the variation in profile is significant with most women referring to second trimester abortion due to later diagnosis of pregnancy, women facing financial and logistic barriers to health care, victims of violence and women with pregnancy complications or fetal anomalies.

Abstract
Synapses are critical for neuronal communication and brain function. To maintain neuronal homeostasis, synapses rely on autophagy. Autophagic alterations cause neurodegeneration and synaptic dysfunction is a feature in neurodegenerative diseases. In Parkinson's disease (PD), where the loss of synapses precedes dopaminergic neuron loss, various PD-causative proteins are involved in the regulation of autophagy. So far only a few factors regulating autophagy at the synapse have been identified and the molecular mechanisms underlying autophagy at the synapse is only partially understood. Here, we describe Endophilin-B (EndoB) as a novel player in the regulation of synaptic autophagy in health and disease. We demonstrate that EndoB is required for autophagosome biogenesis at the synapse, whereas the loss of EndoB blocks the autophagy induction promoted by the PD mutation LRRK2G2019S. We show that EndoB is required to prevent neuronal loss. Moreover, loss of EndoB in the Drosophila visual system leads to an increase in synaptic contacts between photoreceptor terminals and their post-synaptic synapses. These data confirm the role of autophagy in synaptic contact formation and neuronal survival.

Abstract
Automatic quantification of image parameters is a powerful and necessary tool to explore and analyze crucial cell biological processes. This article describes two ImageJ/Fiji automated macros to approach the analysis of synaptic autophagy and exosome release from 2D confocal images. Emerging studies point out that exosome biogenesis and autophagy share molecular and organelle components. Indeed, the crosstalk between these two processes may be relevant for brain physiology, neuronal development, and the onset/progression of neurodegenerative disorders. In this context, we describe here the macros "Autophagoquant" and "Exoquant" to assess the quantification of autophagosomes and exosomes at the neuronal presynapse of the Neuromuscular Junction (NMJ) in Drosophila melanogaster using confocal microscopy images. The Drosophila NMJ is a valuable model for the study of synapse biology, autophagy, and exosome release. By use of Autophagoquant and Exoquant, researchers can have an unbiased, standardized, and rapid tool to analyze autophagy and exosomal release in Drosophila NMJ.

Abstract
Booster vaccine doses are meant to revive the fading immunity created by prior exposure to an immunizing antigen. They stabilize the antibody response ultimately leading to longer and higher protection against pathogens. Immunological studies done for COVID-19 vaccines have documented a steady decrease in antibody levels among vaccinated individuals and evidence of breakthrough infections over a course of time. With an emerging science behind the need for COVID-19 vaccine booster shots, there equally is a contrasting idea regarding its absolute necessity.

Abstract
Background Thyroid disorders are emerging public health issues. Clients' awareness is crucial for prevention, early diagnosis, and treatment of the thyroid disorders. Studies, assessing knowledge on thyroid disorders among Nepalese population, is lacking. Objective To assess the awareness of thyroid disorders among women, a susceptible subgroup, and find the correlates of poor knowledge. Method A cross-sectional study was conducted among 423 women at the gynecological outpatient department of Tribhuvan University Teaching Hospital. Eighteen-item scale, with a Cronbach's Alpha of 0.913, was developed to assess participant's knowledge on various constructs of thyroid disorder. A linear regression model with Bootstrap approach was used to identify the predictors of the total knowledge score. Result The mean (±SD) age of the participant was 29.2 ± 7.0 years. About 49% of the women had inadequate knowledge, defined at or below the mean cumulative knowledge score. In linear regression, the total knowledge score was significantly lower among participants who were Janajati (β=-2.87, BCa 95%CI=-4.61, -1.11), illiterate (β=- 6.37, BCa 95%CI =-9.14, -3.21), and low income (β=-3.76, BCa 95%CI=-5.68, -1.83). Likewise, a university education (β=5.94, BCa 95%CI=3.50, 8.26), working status (β=4.04, BCa 95%CI=2.19, 5.81), urban residence (β=2.06, BCa 95%CI=0.02, 3.96) and family history (β=2.20, BCa 95%CI=0.71, 3.63) of thyroid disorder predicted higher knowledge score. Conclusion This study identified a poor level of knowledge on thyroid disorders among Nepali women and thus proposes them to be an important subgroup for an intervention or policy aimed at promoting awarenessof thyroid disorders. The findings also warrant increased awareness among these population through hospital and communitybased behavior change communication campaigns.

Abstract
Nephrolithiasis is one of the most common kidney diseases, with poorly understood pathophysiology, but experimental study has been hindered by lack of experimentally tractable models. Drosophila melanogaster is a useful model organism for renal diseases because of genetic and functional similarities of Malpighian (renal) tubules with the human kidney. Here, we demonstrated function of the sex-determining region Y protein-interacting protein-1 (Sip1) gene, an ortholog of human Na+/H+ exchanger regulatory factor (NHERF1), in Drosophila Malpighian tubules and its impact on nephrolithiasis. Abundant birefringent calculi were observed in Sip1 mutant flies, and the phenotype was also observed in renal stellate cell-specific RNA interference Sip1 knockdown in otherwise normal flies, confirming a renal etiology. This phenotype was abolished in rosy mutant flies (which model human xanthinuria) and by the xanthine oxidase inhibitor allopurinol, suggesting that the calculi were of uric acid. This was confirmed by direct biochemical assay for urate. Stones rapidly dissolved when the tubule was bathed in alkaline media, suggesting that Sip1 knockdown was acidifying the tubule. SIP1 was shown to collocate with Na+/H+ exchanger isoform 2 (NHE2) and with moesin in stellate cells. Knockdown of NHE2 specifically to the stellate cells also increased renal uric acid stone formation, and so a model was developed in which SIP1 normally regulates NHE2 activity and luminal pH, ultimately leading to uric acid stone formation. Drosophila renal tubules may thus offer a useful model for urate nephrolithiasis.

Adherence assessment practices in haemodialysis settings: A qualitative exploration of nurses and pharmacists' perspectives. J Clin Nurs 2019; 28:2197-2205. [PMID: 30786082 DOI: 10.1111/jocn.14821] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2018] [Revised: 01/14/2019] [Accepted: 02/09/2019] [Indexed: 12/26/2022]
Abstract
AIMS AND OBJECTIVES To explore clinician assessment of patient adherence and identify strategies to improve adherence assessment practices in haemodialysis settings. BACKGROUND Patients with chronic kidney disease undergoing haemodialysis are typically prescribed complex regimens; as such, they are at high risk of medication nonadherence. Current clinical practices focus on prescribing medications; however, little attention is paid to measuring and ensuring patient adherence to their prescribed treatments. DESIGN A qualitative study. METHODS Semi-structured individual interviews were conducted in November and December 2016, with 12 nurses and 6 pharmacists, working in Australian haemodialysis settings. The study was conducted and reported in accordance with COREQ guidelines. RESULTS Participants were 25-60 years old and had 1-27 years of experience in dialysis. Seven themes related to assessing adherence were identified: prioritisation of resources, interplay between workload and available time, awareness of formalised adherence measures and training deficits, concerns about practicality/suitability of adherence measures, communication of assessment services, patient participation and trust. Three themes related to strategies for improving adherence assessment practices were identified: formalisation of adherence assessment process, integration of assessment processes and tools into routine, and use of multidisciplinary support to assess and promote adherence. CONCLUSIONS Current adherence assessment practices could be improved through formalisation and integration of the assessment process into dialysis unit policy/procedures. Additionally, as barriers to assessing adherence were identified at organisational, professional and patient levels, there is a need to address barriers from each level in order to improve adherence assessment practices in haemodialysis settings. RELEVANCE TO CLINICAL PRACTICE This qualitative study highlights the challenges and practical ways by which adherence assessment practices could be improved in haemodialysis settings. This would encourage renal clinicians to actively participate in adherence assessment and promotion activities to ensure patients benefit from their therapies.

Abstract
The insect renal (Malpighian) tubule has long been a model system for the study of fluid secretion and its neurohormonal control, as well as studies on ion transport mechanisms. To extend these studies beyond the boundaries of classical physiology, a molecular genetic approach together with the 'omics technologies is required. To achieve this in any vertebrate transporting epithelium remains a daunting task, as the genetic tools available are still relatively unsophisticated. Drosophila melanogaster, however, is an outstanding model organism for molecular genetics. Here we describe a technique for fluid secretion assays in the D. melanogaster equivalent of the kidney nephron. The development of this first physiological assay for a Drosophila epithelium, allowing combined approaches of integrative physiology and functional genomics, has now provided biologists with an entirely new model system, the Drosophila Malpighian tubule, which is utilized in multiple fields as diverse as kidney disease research and development of new modes of pest insect control.

Abstract
Background Integrated curriculum enhances students' learning and the retention of knowledge. At Patan Academy of Health Sciences, integrated organ system based curriculum is used with Problem Based Learning as the principle teaching learning method to foster students' learning. In addition, other approaches of integration were under taken such as integrated assessment; logical arrangement teaching learning methods (lectures and practicals); joint effort of faculty in curriculum planning and delivery; conducive environment to foster hidden curriculum. This study describes the perception of faculty and students on integration characteristics of Basic Science curriculum. Objective To measure the integration characteristics of Basic Science Curriculum. Method Tool was developed to measure integration characteristics of Basic Science Curriculum and ensure whether such planned integration has been achieved. Mixed method was used to measure the perception of the integration characteristics i) quantitatively by questionnaire survey to faculty and students ii) qualitatively by in-depth interview of students. Result Both faculty and students perceived that all the blocks in Basic Science was well integrated in the quantitative questionnaire survey. But, in the in-depth interview, students perceived integration of curriculum in organ system blocks were better integrated compared to Principle of Human Biology blocks where fundamentals of basic science disciplines were delivered. Students reflected that Problem Based Learning not only integrated Basic Science disciplines but also with clinical sciences and the social context. But, students perceived that Community Health Sciences curriculum was not so well integrated with Basic Science subjects. Conclusion Overall, this study showed that planned integration in Basic Science curriculum was successfully executed during curriculum implementation.

Abstract
Background: Age standardized cervical cancer incidence rate in Nepal is 19.2/100,000 woman, compared with 14.0 worldwide. Similarly, mortality rate is 12.0 women which is significant in comparison with 6.8 worldwide. Cervical intraepithelial neoplasm is a precursor lesion, having high transformation rate into the cervical carcinoma. Data clearly indicates that CIN 2 and 3 has more progression into cervical carcinoma. Despite the fact that Papanicolaou test has remained an important tool in the screening for cervical cancer and has contributed in significant decrease in cervical cancer, sensitivity and specificity of conventional Papanicolaou test is quite low. Colposcopy is visual inspection of cervix under magnification. Study revealed that the positive predictive rate of the colposcopic impression is better as the cervical lesion is more severe. Aim: To find out the significance of colposcopy in the detection of dysplastic cervical lesions and possible use of this method as a screening tool. Methods: This is an observational study done at Cancer Care Foundation, Nepal done from a period of January 2015 to February 2018. Permission was obtained from ethical committee and written consent was obtained from the patients. All the patients suspected having dysplastic or invasive lesions or in whom colposcopy-guided biopsy was performed; were included in the study. Relevant data were collected which included age, colposcopic diagnosis, histopathological diagnosis. Data were entered into Microsoft Excel and statistical analysis was done from statistical package SPSS 21. Results: 6109 females were screened through colposcopy. Out of these 900 patients underwent colposcopy-guided biopsy for being suspected of dysplastic lesions or inflammatory lesions. Mean age of females was 40.65 years. With colposcopy, 407 (45.2%) were suspected to have low grade lesion, followed by 401 (44.6%) high grade lesion and 15 (1.7%) carcinoma. Nonneoplastic lesions were suspected in 77 (8.6%) females. In the histopathological examination low grade dysplasia was observed in 403 (44.8%) followed by 250 (27.8%) high grade dysplasia and 8 (0.9%) carcinoma in-situ or invasive carcinoma. Similarly, 239 (26.6%) patients had nonneoplastic lesions. In colposcopy, high grade lesions were suspected more frequently in females of 41-50 years age group than in 31-40 years age group ( P < 0.01). Correlation between increasing age and dysplastic lesions were also observed ( P < 0.05). There was significant correlation between colposcopic diagnosis and histopathological diagnosis with a P value < 0.01. The sensitivity of colposcopy to diagnose dysplastic lesions were high 96.44% with positive predictive value of 62.65%. The specificity of colposcopy to diagnose various grades of dysplastic lesions is 34.98%. Conclusion: Colposcopy is highly sensitive method of screening dysplastic cervical lesions and should be used more frequently as a screening purpose.

Abstract
We experimentally demonstrate backward emission of high-harmonics of a near-infrared laser from MgO and Si crystals in the direction of specular reflection. We show that the variation of the high-harmonic power with the angle of incidence can be predicted with nonlinear reflection coefficients derived originally for perturbative nonlinearities. A comparison of transmission and reflection geometries suggests that backward-propagating high-harmonics are an excellent reference to study nonlinear propagation of intense light in solids. Backward emission will enable phase matching of the high-harmonic beam and the integration of the functionalities of extended gas-phase high-harmonic beamlines into a single optical element. The potential to achieve phase matching paves the way to solid-state based high-harmonic sources with higher flux than the best transmission-based sources, where high-harmonics are strongly absorbed by the crystal itself.

Abstract
Soybean is a critical food and nutritional security crop in Rwanda. Promoted by the Rwandan National Agricultural Research System for both adults and as an infant weaning food, soybean is grown by approximately 40% of households. Soybean may be susceptible to the growth of mycotoxin-producing moulds; however, data has been contradictory. Mycotoxin contamination is a food and feed safety issue for grains and other field crops. This study aimed to determine the extent of mycotoxin contamination in soybean, and to assess people's awareness on mycotoxins. A farm-level survey was conducted in 2015 within three agro-ecological zones of Rwanda suitable for soybean production. Soybean samples were collected from farmers (n=300) who also completed questionnaires about pre-and post-harvest farm practices, and aflatoxin awareness. The concentration of total aflatoxin in individual soybean samples was tested by enzymelinked immunosorbent assay (ELISA) using a commercially-available kit. Other mycotoxins were analyzed using liquid chromatography-mass spectrometry (LCMS/MS) on 10 selected sub samples. Only 7.3% of the respondents were aware of aflatoxin contamination in foods, but farmers observed good postharvest practices including harvesting the crop when the pods were dry. Using enzyme-linked immunosorbent assay (ELISA), only one sample had a concentration (11 µg/kg) above the most stringent EU maximum permitted limit of 4 µg/kg. Multi-mycotoxins liquid chromatography-mass spectrometry (LC-MS/MS) results confirmed that soybeans had low or undetectable contamination; only one sample contained 13µg/kg of sterigmatocystine. The soybean samples from Rwanda obtained acceptably low mycotoxin levels. Taken together with other studies that showed that soybean is less contaminated by mycotoxins, these results demonstrate that soybean can be promoted as a nutritious and safe food. However, there is a general need for educating farmers on mycotoxin contamination in food and feed to ensure better standards are adhered to safeguard the health of the consumers regarding these fungal secondary metabolites.

Abstract
Herpes Zoster (HZ) is a segmental eruption of grouped vesicles that are confined to a dermatome. There is dermatomal distribution of skin rash, which is unilateral. When two non contagious dermatomes are involved, if affected bilaterally, it is called HZ duplex bilateralis; if unilaterally, unilateralis. HZ duplex bilateralis is extremely rare in immunocompetent children. This report describes a 12-year old girl with bilateral HZ. She had no features of immunosupression. She was treated with oral acyclovir for one week. No complications, including post herpetic neuralgia, were observed during the follow up period of three months.

Abstract
Background End-stage kidney disease patients undergoing haemodialysis are prescribed with multiple complex regimens and are predisposed to high risk of medication nonadherence. The aims of this study were to explore factors associated with medication adherence, and, to examine the differential perspectives on medication-taking behaviour shown by adherent and nonadherent haemodialysis patients. Methods A qualitative exploratory design was used. One-on-one semi-structured interviews were conducted with 30 haemodialysis patients at the outpatient dialysis facility in Hobart, Australia. Patient self-reported adherence was measured using 4-item Morisky Green Levine scale. Interview transcripts were thematically analysed and mapped against the World Health Organization (WHO) determinants of medication adherence. Results Participants were 44–84 years old, and were prescribed with 4–19 medications daily. More than half of the participants were nonadherent to their medications based on self-reported measure (56.7%, n = 17). Themes mapped against WHO adherence model comprised of patient-related (knowledge, awareness, attitude, self-efficacy, action control, and facilitation); health system/ healthcare team related (quality of interaction, and mistrust and collateral arrangements); therapy-related (physical characteristics of medicines, packaging, and side effects); condition-related (symptom severity); and social/ economic factors (access to medicines, and relative affordability). Conclusions Patients expressed a number of concerns that led to nonadherence behaviour. Many of the issues identified were patient-related and potentially modifiable by using psycho-educational or cognitive-behavioural interventions. Healthcare professionals should be more vigilant towards identifying these concerns to address adherence issues. Future research should be aimed at understanding healthcare professionals’ perceptions and practices of assessing medication adherence in dialysis patients that may guide intervention to resolve this significant issue of medication nonadherence.

Abstract
BACKGROUND The impact of medication regimen complexity on adherence in hemodialysis patients is unknown. We investigated regimen complexity, perceived burden of medicines (PBM) and health-related quality of life (HR-QoL) as potential predictors of adherence. METHODS Adult (≥18 years) hemodialysis patients were included. Data on medication regimen complexity index (MRCI), self-reported and objective adherence, comorbidity index, PBM and HR-QoL were obtained using established measures. Sociodemographic and clinical characteristics were collected during interviews and by reviewing medical records. Predictors of adherence were determined using logistic regression. RESULTS Fifty-three out of 70 hemodialysis patients participated (response rate 75%; male 58.5%; age 67.9 ± 11.5 years). The mean MRCI, HR-QoL and PBM scores were 27.0 ± 10.9, 0.70 ± 0.13 and 1.7 ± 0.6, respectively. Based on self-reports, 43.4% (n = 23) were adherent, whereas for a subset of patients analyzed using objective measure (n = 33), much lower adherence rate was observed (27.3%, n = 9). The self-reported and objective measures were significantly correlated (r = 0.43, p = 0.01). Older age was the only significant predictor of self-reported adherence (OR 1.05; 95% CI 1.00-1.11) whereas older age (OR 1.10; 95% CI 1.00-1.21), higher comorbidity (OR 1.58; 95% CI 1.03-2.42) and MRCI (OR 1.14; 95% CI 1.02-1.27) were independent predictors of objective adherence. CONCLUSIONS The findings of this exploratory study suggest that older patients with high comorbidities and highly complex regimen are more likely to be adherent based on an objective measure. Future research is needed using objective measures of adherence suitable for all patients and reflecting all medications.

Abstract
Background Peripheral neuropathy is one of the most common and distressing late complication of diabetes mellitus. Ignorance of the complications may develop foot ulcers and gangrene requiring amputation. Objective The main objective of this study is to find out the prevalence of sensory neuropathy in type 2 diabetes mellitus and to compare it with the duration of disease. Method Two hundred seventy one patients with type 2 diabetes mellitus of both gender age 30 years and above willing to participate were included in this study. Patients having hypothyroidism, rheumatoid arthritis, B12 deficiency, cerebrovascular disease, chronic musculoskeletal disease, Parkinson's disease, alcohol abuse, chronic renal or liver failure and cancer were excluded from the study. Touch, pin prick and vibration sensation were tested. Vibration perception threshold was recorded from six different sites of the sole of each foot using Biothesiometer. Result Two hundreds seventy one type 2 diabetic outpatients were studied. The mean age was 59.81±22.85 years. The overall prevalence of diabetic sensory neuropathy in the study population was 58.70%. A rising trend of diabetic sensory neuropathy with increasing age and duration of diabetes was observed. Neuropathy was found more in patients having urinary microalbuminuria. Burning and pins and needles sensation were most common symptoms. Conclusion The overall prevalence of diabetic sensory neuropathy in the study population was 58.70% (mean age 59.81±22.85 yrs), and its prevalence increased with duration of diabetes and increasing age. Its prevalence was found more in patients having microalbuminuria.

Abstract
INTRODUCTION Tuberculosis (TB) remains a global health problem. Drug resistance, treatment duration, complexity, and adverse drug reactions associated with anti-TB regimens are associated with treatment failure, prolonged infectiousness and relapse. With the current set of anti-TB drugs the goal to end TB has not been met. New drugs and new treatment regimens are needed to eradicate TB. AREAS COVERED Literature was explored to select publications on drugs currently in phase II and phase III trials. These include new chemical entities, immunotherapy, established drugs in new treatment regimens and vaccines for the prophylaxis of TB. EXPERT OPINION Well designed trials, with detailed pharmacokinetic/pharmacodynamic analysis, in which information on drug exposure and drug susceptibility of the entire anti-TB regimen is included, in combination with long-term follow-up will provide relevant data to optimize TB treatment. The new multi arm multistage trial design could be used to test new combinations of compounds, immunotherapy and therapeutic vaccines. This new approach will both reduce the number of patients exposed to inferior treatment and the financial burden. Moreover, it will speed up drug evaluation. Considering the investments involved in development of new drugs it is worthwhile to thoroughly investigate existing, non-TB drugs in new regimens.

Abstract
INTRODUCTION Eclampsia is a preventable and treatable cause of maternal morbidity and mortality with poor feto-maternal outcome in developing countries. Despite development in the level of health education expertise in human resources and institutional obstetric care in our country, the delay in early recognition of the problem, transportation to proper health facility and getting proper expert care are major hurdles to reduce complications. Therefore, we decided to study feto-maternal outcomes in our setting. METHODS A retrospective cross-sectional hospital based study carried out in Nobel Medical College,Biratnagar, from 17th June 2014 to 16th June 2015. Details and data obtained from Medical Record Section were analysed. All patients with eclampsia were included and fetomaternal outcomes measured in terms of complications. Simple descriptive statistical method was applied for analysis. RESULTS Among 8,066 deliveries, 112 had eclampsia with incidence of 13.8/1000 deliveries. Majority (41%) were of <19 years of age. Above 90% were unbooked. Aoubt 63.4% were primiparas and 83% had antepartum eclampsia. Eclamptic fits were more common (41.6%) in 37-40 weeks period of gestation. Fits to delivery interval was more than six hours in 89.1% women and 69.3% women underwent caesarean delivery. About 18.9% women developed eclampsia related complications.Common causes of maternal deaths (5.36%) were pulmonary edema, aspiration pneumonia,cerebrovascular accidents and HELLP syndrome. Perinatal death was nine percent. CONCLUSIONS Although the obstetric care facilities are improving with time, the feto-maternal outcomes are still poor in our country. Therefore early recognition and proper management are vital to tackle this challenge.

Abstract
BACKGROUND Avian influenza (AI) is currently a threat to global health. Prevention and control of AI depends on the knowledge and preventive practices of the poultry workers as well as of general population. This study aims to assess knowledge and preventive practices related to AI among poultry workers. METHODS Cross-sectional study was carried out among poultry workers of Kamalamai Municipality, Sindhuli. Data was collected from randomly selected 122 respondents through face-to-face interview. The collected data was entered in Epi-data version 3.1 and analyzed in terms of descriptive statistics (proportion, 95% CI, mean and standard deviation) by using SPSS, version 20. A scoring system was used to assess knowledge and preventive practices. RESULTS Out of total, 93.4% (95% CI, 87.6- 96.6%) of the respondents had heard about AI. More than half (54.9%) of the respondents had poor knowledge on AI. Only 5.3% of respondents had good preventive practice against AI. 30.3% respondents had good knowledge and good practice and 24.6% had poor knowledge as well as poor practice. 20.5% of the respondents had good practice but poor knowledge, whereas, 24.6% had good knowledge but poor practice towards prevention. CONCLUSIONS The knowledge and practice of AI among poultry workers were low. The groups should be targeted for appropriate intervention based on whether they lack knowledge or practice or both.

[PMID: 26636968 PMCID: PMC4670103 DOI: 10.1371/journal.pone.0144119] [Citation(s) in RCA: 128] [Impact Index Per Article: 14.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2015] [Accepted: 11/15/2015] [Indexed: 11/19/2022] Open
Abstract
Background End-stage kidney disease (ESKD) patients are often prescribed multiple medications. Together with a demanding weekly schedule of dialysis sessions, increased number of medicines and associated regimen complexity pre-dispose them at high risk of medication nonadherence. This review summarizes existing literature on nonadherence and identifies factors associated with nonadherence to medication therapy in patients undergoing haemodialysis. Methods A comprehensive search of PubMed, Embase, CINAHL, PsycInfo, and Cochrane Database of Systematic Reviews covering the period from 1970 through November 2014 was performed following a predefined inclusion and exclusion criteria. Reference lists from relevant materials were reviewed. Data on study characteristics, measures of nonadherence, prevalence rates and factors associated with nonadherence were collected. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines was followed in conducting this systematic review. Results Of 920 relevant publications, 44 were included. The prevalence of medication nonadherence varied from 12.5% to 98.6%, with widespread heterogeneity in measures and definitions employed. Most common patient-related factors significantly associated with nonadherence were younger age, non-Caucasian ethnicity, illness interfering family life, being a smoker, and living single and being divorced or widowed. Similarly, disease-related factors include longevity of haemodialysis, recurrent hospitalization, depressive symptoms and having concomitant illness like diabetes and hypertension. Medication-related factors such as daily tablet count, total pill burden, number of phosphate binders prescribed and complexity of medication regimen were also associated with poor adherence. Conclusions A number of patient-, disease-, and medication-related factors are associated with medication nonadherence in haemodialysis patients. Clinicians should be aware of such factors so that adherence to medications can be optimised in haemodialysis patients. Future research should be directed towards well-designed prospective longitudinal studies developing standard definitions and validating available measurement tools, while focusing on the role of additional factors such as psychosocial and behavioural factors in predicting nonadherence to medications.

Assessment of knowledge and practice of community pharmacy personnel on diabetes mellitus management in Kathmandu district: a cross sectional descriptive study. J Diabetes Metab Disord 2015; 14:71. [PMID: 26396963 PMCID: PMC4578402 DOI: 10.1186/s40200-015-0205-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2015] [Accepted: 09/17/2015] [Indexed: 01/24/2023]
Abstract
Background Pharmacists are the most reachable healthcare professionals to many chronically ill patients. It has been found that pharmacists see patients with diabetes up to five times more often than any other healthcare provider. Therefore, to provide quality health care to patients it is important that they have appropriate knowledge and practice on diabetes mellitus management. Thus, this study was conducted to assess the knowledge and practice of diabetes mellitus management among community pharmacy personnel involved in retail community pharmacies of Kathmandu. Methods Three hundred and fifteen community pharmacies, selected by systematic random sampling were surveyed by using pre-validated self-administered questionnaires. The first set of questionnaire evaluated the community pharmacy personnel’s diabetes knowledge based on a pre-validated 20-item questionnaire. The second set of questionnaire documented about the practice of community pharmacy personnel on diabetes mellitus management which contained 22 questions. Data was entered in EPI Data and analyzed by using SPSS version 20. Results This survey demonstrated that 76.5 % respondents had poor knowledge and 86.4 % had negative practice on diabetes mellitus (DM) management. Only 26.2 % respondents had good knowledge as well as good practice. 31.4 % of respondents had poor knowledge as well as poor practice on DM management. Conclusions Laws and regulations regarding community pharmacy personnel need to be implemented. There should be more advanced and experiment based training. Additionally, the provision for further education curriculum in pharmacy education should be implemented which should intensively include disease and proper management. Guidelines covering diabetes care should be distributed and implemented throughout community pharmacies.

Defensive Behavior against Noxious Heat Stimuli Is Declined with Aging Due to Decreased Pain-Associated Gene Expression in Drosophila. Biomol Ther (Seoul) 2015; 23:290-5. [PMID: 25995829 PMCID: PMC4428723 DOI: 10.4062/biomolther.2014.147] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2014] [Revised: 02/15/2015] [Accepted: 02/26/2015] [Indexed: 12/30/2022] Open
Abstract
Aging is defined as a collective process that alters organism’s functional capacity and appearance over the course of life. Apart from an increase in susceptibility to many diseases, aging affects the cellular system that is responsible for decoding painful stimuli. Yet, aging-associated molecular mechanisms of pain perception remains elusive. Using Drosophila, we showed a decrease in temperature tolerance and a reduction in high temperature thermal avoidance with aging. Locomotor activity assay demonstrated that the age-dependent changes in heat nociception did not stem from the general decline in muscular activity. However, we identified pain-related gene expression alteration with aging. We anticipate that our findings would help opening a new window onto developing the optimal pain treatment for the elderly.

Abstract
Aims: To analyse causes of maternal deaths and to identify avoidable factors. Methods: This was a retrospective analysis of maternal deaths, during a period of one year from 15th April, 2011-15th April, 2012, at Nobel Medical College Teaching Hospital, Biratnagar in the Eastern Region of Nepal case files and hospital records being the data sources. All the maternal deaths were recorded. Results: In one year study period, out of a total of 2,754 deliveries, there were 8 maternal deaths giving maternal mortality ratio of 310/100,000 live births. Three of them resulted from an induced abortion mishap and five of them were obstetric deaths. Four of the direct obstetric deaths resulted from complications of pregnancy induced hypertension (PIH) of which one case died due to traumatic post partum hemorrhage postpartum hemorrhage (PPH) as a result of torrential bleeding from extensive vaginal wall tear. One indirect obstetric death occurred in a case of twin pregnancy with severe anemia and congestive cardiac failure. Conclusions: Provision of safe abortion services is still not available to many women despite of legalization of abortion in Nepal. Quality antenatal care services would be helpful in avoiding maternal mortality in many situations by detecting and managing medical complications of pregnancy.

Abstract
Single-cycle terahertz fields generated by coherent transition radiation from a relativistic electron beam are used to study the high field optical response of single crystal GaAs. Large amplitude changes in the sub-band-gap optical absorption are induced and probed dynamically by measuring the absorption of a broad-band optical beam generated by transition radiation from the same electron bunch, providing an absolutely synchronized pump and probe geometry. This modification of the optical properties is consistent with strong-field-induced electroabsorption. These processes are pertinent to a wide range of nonlinear terahertz-driven light-matter interactions anticipated at accelerator-based sources.

Abstract
BACKGROUND Cesarean section has been identified as one of the commonest indication for blood transfusion in obstetric practice because it involves risk of major intra-operative blood loss. Different figures varying from less than 500 ml to more than 1000 ml have been quoted as estimated blood loss associated with caesarean section. There is also a wide variation in blood ordering practices for this surgery. OBJECTIVE The objective of this study is to evaluate the blood ordering practice and transfusion for cesarean sections at our institute, to see post-operative drop in hemoglobin and hematocrit and to correlate those parameters with the duration between uterine incision and repair. METHODS In this prospective observational study, non-randomised purposive sample was taken from 121 ladies who underwent elective and emergency cesarean section at the department of obstetrics of Dhulikhel Hospital-Kathmandu University Hospital. Post-cesarean drop in hemoglobin and hematocrit and their relation with duration of uterine manipulation was calculated. Cross-match to transfusion (C/T ratio) ratio, transfusion probability (%T) and transfusion index (Ti) were also calculated. RESULTS Most frequent blood group was found to be O positive (38%) among those ladies. Average post-cesarean drop in hemoglobin was 1.52±1.27 gm/dl and drop in haematocrit was 5.49±4.1%. Post-operative drop in hemoglobin and haematocrit had weak and positive linear relation with duration between uterine incision and repair. Cross-match to transfusion ratio was 1, transfusion probability 100% and transfusion index was 2. CONCLUSION There is no need of routine cross-matching of blood for cesarean section. Only grouping with confirmation of availability should be done for emergency situation.

Abstract
OBJECTIVES The aims of this study were to evaluate the quality of randomized controlled trial (RCT) abstracts published in the field of oncology and identify characteristics associated with better reporting quality. STUDY DESIGN AND SETTING All phase III trials published during 2005-2007 [before Consolidated Standards of Reporting Trials (CONSORT)] and 2010-2012 (after CONSORT) were searched electronically in MEDLINE/PubMed and retrieved for review using an 18-point overall quality score (OQS) for reporting based on the CONSORT for Abstract guidelines. Descriptive statistics followed by multivariate linear regression were used to identify features associated with improved reporting quality. RESULTS The mean OQS was 8.2 (range: 5-13; 95% confidence interval (CI): 8.0, 8.3) and 9.9 (range: 5-18; 95% CI: 9.7, 10.2) in the pre- and post-CONSORT periods, respectively. The method for random sequence generation, allocation concealment, blinding details, and funding sources were missing in pre-CONSORT abstracts and insufficiently reported (<20%) in post-CONSORT abstracts. A high impact factor (P < 0.001) and the journal of publication (P < 0.001) were independent factors that were significantly associated with higher reporting quality on multivariate analysis. CONCLUSION The reporting quality of RCT abstracts in oncology showed suboptimal improvement over time. Thus, stricter adherence to the CONSORT for Abstract guidelines is needed to improve the reporting quality of RCT abstracts published in oncology.

Evaluation of predictions of volatile fatty acid production rates by the Molly cow model. J Dairy Sci 2013; 97:354-62. [PMID: 24268399 DOI: 10.3168/jds.2012-6199] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2012] [Accepted: 10/08/2013] [Indexed: 11/19/2022]
Abstract
Predicting ruminal volatile fatty acid (VFA) production is important, as VFA are an energy source to the animal, affect nutrient partitioning, and dictate methane production. The VFA production submodel in the Molly cow model was evaluated using data from 8 publications that reported VFA production rates for cattle. Evaluations were conducted with ruminal water balance predictions enabled and the ruminal VFA stoichiometry coefficients set to "mixed" for all diets, or "mixed" when forage represented between 20 and 80% of the diet, "concentrate" when <20% forage, or "forage" when >80% forage. Prediction errors were relatively insensitive to changes in VFA coefficients by diet type. Root mean square prediction errors (RMSPE) were 63, 63, and 49% for acetate, propionate, and butyrate production rates, respectively. A large proportion of the error was slope bias for acetate and butyrate, and a modest proportion for propionate. Because interconversions between acetate and propionate represent approximately 15% of the variation in net production rates, lack of such consideration in the model may contribute to the substantial model prediction errors. The potential of using thermodynamic equations to predict interconversions was assessed using observed ruminal pH and VFA concentrations from 2 studies and assuming constant hydrogen pressure and concentrations of CO₂, H₂O, adenosine diphosphate, ATP, and inorganic P. Rate constants for conversion of acetate to propionate and propionate to acetate were derived independently from the control treatments and used to predict the fluxes for the other treatment. The observed changes in VFA concentrations and pH explained the observed changes in conversion of acetate to propionate, but overpredicted the change in the propionate to acetate flux in one study. When applied to the other study, the equations predicted the increase in propionate to acetate flux, but failed to predict the observed reduction in acetate to propionate flux. The inability to predict responses accurately may be due to a lack of data for controlling factors other than pH and VFA concentrations.
