Patient experiences of outpatient hysteroscopy

OBJECTIVES

Patient perspectives have an important role in improving the quality of outpatient hysteroscopy (OPH) services. Understanding women's experiences can help provide important insights regarding the OPH journey. The purpose of this paper is to share perspectives and reflect on the experiences of women that participated in a national benchmarking OPH survey. In addition, we explore the correlation between women's experience of OPH and reported pain scores.

MATERIAL AND METHODS

Over a two-month period, 5151 women took part in the national OPH survey. Free text comments relating to women's OPH experience, collected as part of the survey, were subjected to qualitative analysis using NVivo 12 software to provide a better understanding of the OPH journey. In addition, correlations were drawn between the qualitative and quantitative data collected for pain scores and satisfaction using SPSS software.

RESULTS

1720 (33.3%) women provided comments on their OPH experience. Qualitative thematic analysis generated themes that were divided into positive (82%) and negative (7%) experiences of care. Potential areas of improvement in relation to the OPH service were highlighted in 11% of themes. Most women regarded OPH as a safe, tolerable, and well delivered outpatient service. Quantitative analysis showed that 1829 (35.5%) women reported procedural pain between 70 and 100 mm. These women reported equivalent quality of care on a 10 cm visual analogue scale (9.71 [SD1.04] vs. 9.76 [0.73]; P = 0.06) but were more likely to decline having the procedure done in the same way again (19.4% vs. 3.1%; RR 6.30, 95% CI 5.06 to 7.83) compared to women with pain scores < 70 mm.

CONCLUSION

Qualitative data supports the usefulness, safety, tolerability, and acceptance of hysteroscopy in an outpatient setting by most women. However, the reasons for high procedural pain, poor tolerability and negative experiences warrant review and exploration of both individual patient and relevant institutional factors including training, equipment, and local processes.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

BACKGROUND

Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.

METHODS

This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low-middle-income countries.

RESULTS

In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of 'single-use' consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low-middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.

CONCLUSION

This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high- and low-middle-income countries.

Effectiveness of health education module on work safety culture in improving knowledge, attitudes and practices: a cluster randomized controlled trial among public sector administrative workers in Nigeria

INTRODUCTION

Studies have shown that a workplace safety culture (WSC) is lacking among the general workforce in Nigeria. Poor WSC can adversely impact workers' health and high remedial costs for employers. To improve WSC, workers need to improve related knowledge, attitude, and practices (KAP) towards WSC through effective health interventional programs at the workplace. The main objective of this study is to develop, implement and evaluate the effectiveness of the Work Safety Culture Health Education Module (WSCHEM). The specific goals are to improve KAP related to office ergonomics towards WSC among public sector administrative workers in Abeokuta, Nigeria MATERIALS AND METHODS: The study was a two-armed, singleblinded cluster randomised controlled trial (CRCT) involving 247 public sector administrative workers from clusters of 20 ministries in Abeokuta, Southwestern Nigeria. The intervention group was given WSCHEM, whereas the waitlist group received a seminar on team building and leadership skills and received the WSCHEM after the intervention program ended. The evaluation was done three times using the first formal validated, self-administered Work Safety Culture Questionnaire (WSCQ) among the administrative workers: first at baseline, second at 1 month, and third at 3 months post-intervention.

RESULT

The results showed no statistically significant differences between groups regarding the respondents' characteristics (socio-demographic and occupational/officerelated ergonomic factors) and the outcome variables KAP towards WSC at baseline. For practices towards WSC, both intervention (β 6.8, 95%CI 4.85, 8.72) and time (β 6.2, 95%CI 4.49, 7.94) significantly improved the respondents' practices towards WSC in the per-protocol analysis. In the secondary outcomes, both knowledge of WSC, intervention (β 3.5, 95%CI 2.8, 4.2) and time (β 3.4, 95%CI 2.7, 5.9); and attitudes towards WSC, intervention (β1.7, 95%CI 1.25, 2.23) and time (β 2.3, 95%CI 1.92, 2.76) significantly improved the respondents' level of knowledge and attitudes respectively towards WSC.

CONCLUSION

The intervention, WSCHEM, was effective in improving the administrative workers' KAP towards WSC, as demonstrated by the significance between and within-group differences.

Role of Doppler Ultrasound in Diagnosis of Hepatocellular Carcinoma with Histopathological Correlation

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world and the leading cause (possibly third) of cancer mortality. In a present scenario, HCC displays a challenging clinical problem worldwide. Good-quality ultra sound with careful evaluation of the hepatobiliary system can be a screening examination for HCC in patients at risk. The aim of the study was to determine the diagnostic accuracy of the Doppler sonography for differentiation of hepatocellular carcinoma (HCC) from other focal liver lesions. It was a cross-sectional survey, conducted in the Department of Radiology& Imaging, Mymensingh Medical College, Mymensingh, Bangladesh from January 2017 to December 2018. A total of 70 patients with space occupying lesions on ultrasound were included in this study while pregnant women were excluded. All patients were examined by gray scale ultrasonography, color Doppler and FNAC. To visualize the blood flow, standard color Doppler sonography was used for each lesion. Within the lesions, pulsed Doppler samples were assessed whenever possible on the basis of pulsatile flow & finally resistive index (RI) of intra-tumoral and peritumoral arterial flow was studied. After evaluating by Doppler sonography (CDFI and Spectral analysis), FNAC was done and the specimen was sent to the Department of Pathology for Cytopathological examination. Cytopathology were assessed for confirmation of positive and negative cases of HCC. The detection rate of arterial flow in malignant tumors was 85.1% and in benign lesions were 30.4%. Doppler spectrum analysis showed that the resistive index in primary malignant tumors were 0.76±0.12 and in metastatic tumors were 0.80±0.12 and below 0.6 in benign lesions. The difference was significant (p<0.001). This difference was related with its Cytopathological report. The arterial flow identified by CDFI within the liver lesion with RI >0.6 can be regarded as a criterion of malignant tumors and RI<0.6 can be regarded as benign lesions. This study concluded that the combination of color Doppler flow imaging and RI are more useful in differential diagnosis of liver neoplasms.

Serum Magnesium Level and It's Relation in Predicting Adverse In-Hospital Outcome in Patients with First Attack of Myocardial Infarction

Acute myocardial infarction (AMI) patients characterize a large proportion of admissions in coronary care unit and their management and risk stratification is of immense importance. Hypomagnesemia is a long-term risk factor for incident of both myocardial infarction and arrhythmia. We assessed whether serum magnesium levels at admission is associated with arrhythmias and in-hospital mortality in patients with acute myocardial infarction (AMI). The aim of the study was to evaluate the prognostic implications of serum magnesium level in patients with acute myocardial infarction. This cross-sectional observational study was conducted in the department of cardiology in Mymensingh Medical College Hospital from October 2017 to March 2019. Total 259 acute myocardial infarction patients were included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group-I: Patients with acute myocardial infarction with serum magnesium ≥1.82mg/dl. Group-II: Patients with acute myocardial infarction with serum magnesium <1.82mg/dl. Serum magnesium level was measured on admission, and the incidence of in-hospital major cardiac events was assessed. In this study mean serum magnesium level of Group-I, Group-II were 2.21±0.14mg/dl, 1.60±0.15mg/dl respectively. It was statistically significant (p<0.05). In-hospital outcomes of the study group revealed that low risk group patients were uneventful outcome during hospitalization period, they had no any complication. In Group-I patient, 9(4.8%) were developed arrhythmias, 26(13.9%) were developed heart failure, 9(4.8%) were developed cardiogenic shock and 3(1.6%) were died and in Group-II patient, 44(61.10%) developed arrhythmias, 9(12.50%) were developed heart failure, 7(9.7%) were developed cardiogenic shock and 12(16.7%) were died out of them which was statistically significant (p<0.05). Mean duration of hospital stay of the study population according serum magnesium level was in Group-I, 4.27±0.68 days, in Group-II, 5.84±1.05 days which was statistically significant (p<0.05). In conclusion patient with serum magnesium level less than 1.82mg/dl increased the risk of in-hospital arrhythmia and death.

Allergic rhinitis: An indicator of otitis media with effusion in children seen at aminu kano teaching hospital, Kano

BACKGROUND

Allergic rhinitis (AR) is a multifocal IgE-mediated type I hypersensitivity reaction involving nasal mucosa characterized by excessive sneezing, watery rhinorrhea, nasal itching, nasal stuffiness, and eyes itching. Tympanometry is a simple, rapid, and objective test that can be easily carried out. The use of tympanometry in clinical setting can improve detection of middle ear effusion and other middle ear abnormalities. AR has been found to be one of the predisposing factors to developing Otitis Media with Effusion (OME) in children.

PATIENTS AND METHODS

A case-control study was used to determine the prevalence of OME among children with AR as cases and those without allergy as controls. The study participants were children aged 4-12 years with clinical diagnosis of AR attending ENT clinics of Aminu Kano Teaching Hospital, whereas controls were children age 4-12 years without history of AR, ear diseases, or other respiratory system related ailments attending general outpatient clinics in Aminu Kano Teaching Hospital. An interviewer-administered score for AR (SFAR) questionnaire was filled out for all the participants, those with score of 6 and above were selected as cases. The two groups had complete ENT examination and tympanometry done, findings were recorded, and analyzed using SPSS version 21.

RESULTS

The mean age of the cases was 6.8 ± 2.1 years, whereas it was 7.5 ± 2.6 years for the controls. The mean difference was 0.7 and was not statistically significant (t = 2.35, df = 258, P value = 0.20). Type B tympanogram suggesting OME was found in 7.3% of subjects and in 2.8% of controls. Type C tympanogram suggesting negative middle ear pressure was found in 15.5% of subjects and in 4.6% of controls. Type A tympanogram suggesting normal middle ear pressure was found in 75% of subjects and in 90% of controls. Acoustic reflex was found to be absent in 29.6% of subjects and in 15.4% of controls and this found to be statistically significant (χ² = 7.77, df = 1, P value = 0.001). The difference between type A, B, and C tympanograms of subjects and that of controls was found to be statistically significant (Type A χ² = 14.62, df = 4, P value = 0.01, Type B χ² = 14.06, df = 4, P value = 0.01, Type C χ² = 17.01, df = 6, P value = 0.01). Type B tympanogram was used as an indicator to suggest OME for the purpose of this study.

CONCLUSION

Participants with AR were found to have more abnormalities of tympanometric parameters and higher prevalence of type B tympanogram suggesting OME than controls.

Incidence and determinants of catastrophic health expenditure among low-income Malaysian households

INTRODUCTION

Catastrophic health expenditure (CHE) incurs when out-of-pocket health expenditure (OOPHE) exceeds a certain threshold, therefore exposing households to financial hardship, with the low-income population being most vulnerable. Data related to the incidence and determinants of CHE among the low-income population in Malaysia are lacking. This study aims to determine the incidence and determinants of CHE among Malaysian lowincome households.

METHODOLOGY

This is a cross-sectional study using data from 6,720 low-income households from the national Household Expenditure Survey (HES) 2016 conducted from May 2016 till February 2017. The data were analysed using IBM SPSS software 25.0. OOPHE in this study included all spending on healthcare products and services by the household. CHE was identified in households with OOPHE of at least 10% of total monthly income.

RESULTS

The incidence of CHE at the threshold of 10% household income was 1.7% (n=112). The determinants of CHE were households with any accident or medical insurance (p<0.001), having less than five members in a household (p<0.001), presence of elderly (p=0.024), and hospitalisation (p=0.021). In contrast, employment of the head of household (p=0.003) and having a child aged ≤5 years old (p=0.033) protect households from CHE.

CONCLUSION

In the context of this study, the incidence of CHE among the low-income Malaysian population was low, indicating that a majority of the low-income population is protected from financial catastrophe. Regardless, the determinants of CHE among low-income population should be considered in future health policies.

All-cause mortality during the COVID-19 pandemic in Chennai, India: an observational study

BACKGROUND

India has been severely affected by the ongoing COVID-19 pandemic. However, due to shortcomings in disease surveillance, the burden of mortality associated with COVID-19 remains poorly understood. We aimed to assess changes in mortality during the pandemic in Chennai, Tamil Nadu, using data on all-cause mortality within the district.

METHODS

For this observational study, we analysed comprehensive death registrations in Chennai, from Jan 1, 2016, to June 30, 2021. We estimated expected mortality without the effects of the COVID-19 pandemic by fitting models to observed mortality time series during the pre-pandemic period, with stratification by age and sex. Additionally, we considered three periods of interest: the first 4 weeks of India's first lockdown (March 24 to April 20, 2020), the 4-month period including the first wave of the pandemic in Chennai (May 1 to Aug 31, 2020), and the 4-month period including the second wave of the pandemic in Chennai (March 1 to June 30, 2021). We computed the difference between observed and expected mortality from March 1, 2020, to June 30, 2021, and compared pandemic-associated mortality across socioeconomically distinct communities (measured with use of 2011 census of India data) with regression analyses.

FINDINGS

Between March 1, 2020, and June 30, 2021, 87 870 deaths were registered in areas of Chennai district represented by the 2011 census, exceeding expected deaths by 25 990 (95% uncertainty interval 25 640-26 360) or 5·18 (5·11-5·25) excess deaths per 1000 people. Stratified by age, excess deaths numbered 21·02 (20·54-21·49) excess deaths per 1000 people for individuals aged 60-69 years, 39·74 (38·73-40·69) for those aged 70-79 years, and 96·90 (93·35-100·16) for those aged 80 years or older. Neighbourhoods with lower socioeconomic status had 0·7% to 2·8% increases in pandemic-associated mortality per 1 SD increase in each measure of community disadvantage, due largely to a disproportionate increase in mortality within these neighbourhoods during the second wave. Conversely, differences in excess mortality across communities were not clearly associated with socioeconomic status measures during the first wave. For each increase by 1 SD in measures of community disadvantage, neighbourhoods had 3·6% to 8·6% lower pandemic-associated mortality during the first 4 weeks of India's country-wide lockdown, before widespread SARS-CoV-2 circulation was underway in Chennai. The greatest reductions in mortality during this early lockdown period were observed among men aged 20-29 years, with 58% (54-62) fewer deaths than expected from pre-pandemic trends.

INTERPRETATION

Mortality in Chennai increased substantially but heterogeneously during the COVID-19 pandemic, with the greatest burden concentrated in disadvantaged communities. Reported COVID-19 deaths greatly underestimated pandemic-associated mortality.

Varying isoleucine level to determine effects on performance, egg quality, serum biochemistry, and ileal protein digestibility in diets of young laying hens

To ascertain an appropriate level of isoleucine for LSL-LITE layers (23- to 30-week-old), diets containing total isoleucine concentrations (levels) of 0.66 (Control), 0.69, 0.72, 0.75, 0.78, 0.81, and 0.84% were fed as 7 treatments (2730 kcal/kg metabolizable energy) x 7 replicates x 10 birds per replicate. Significance for performance, egg quality, serum biochemistry, and ileal digestibility of protein was determined at P ≤ 0.05. Level, week, and level*week (L*W) were significant for production, egg mass, and feed intake. Level and week were significant for FCR. Week was significant for weight gain. Level was significant for egg weight, specific gravity, and shell thickness; week was also significant for these external egg parameters as well as shape index and proportional shell thickness. L*W was significant for all except shape index. For internal egg measurements, level was significant for proportional yolk, proportional albumen, yolk index, and yolk:albumen. Week was significant for internal egg parameters while L*W significantly affected Haugh unit, proportional albumen weight, yolk index, albumen index, and yolk color. Level was significant for globulin and glucose in serum. Isoleucine at 0.72%, 0.81%, and 0.84% produced the lowest FCR, an important standard in the poultry industry. Considering the low FCR of 1.45 and cost for inclusion as a dietary ingredient, 0.72% isoleucine was chosen for further studies with varying quantities of other branched chain amino acids in diets for young laying hens.

All-cause excess mortality across 90 municipalities in Gujarat, India, during the COVID-19 pandemic (March 2020-April 2021)

Official COVID-19 mortality statistics are strongly influenced by local diagnostic capacity, strength of the healthcare and vital registration systems, and death certification criteria and capacity, often resulting in significant undercounting of COVID-19 attributable deaths. Excess mortality, which is defined as the increase in observed death counts compared to a baseline expectation, provides an alternate measure of the mortality shock-both direct and indirect-of the COVID-19 pandemic. Here, we use data from civil death registers from a convenience sample of 90 (of 162) municipalities across the state of Gujarat, India, to estimate the impact of the COVID-19 pandemic on all-cause mortality. Using a model fit to weekly data from January 2019 to February 2020, we estimated excess mortality over the course of the pandemic from March 2020 to April 2021. During this period, the official government data reported 10,098 deaths attributable to COVID-19 for the entire state of Gujarat. We estimated 21,300 [95% CI: 20, 700, 22, 000] excess deaths across these 90 municipalities in this period, representing a 44% [95% CI: 43%, 45%] increase over the expected baseline. The sharpest increase in deaths in our sample was observed in late April 2021, with an estimated 678% [95% CI: 649%, 707%] increase in mortality from expected counts. The 40 to 65 age group experienced the highest increase in mortality relative to the other age groups. We found substantial increases in mortality for males and females. Our excess mortality estimate for these 90 municipalities, representing approximately at least 8% of the population, based on the 2011 census, exceeds the official COVID-19 death count for the entire state of Gujarat, even before the delta wave of the pandemic in India peaked in May 2021. Prior studies have concluded that true pandemic-related mortality in India greatly exceeds official counts. This study, using data directly from the first point of official death registration data recording, provides incontrovertible evidence of the high excess mortality in Gujarat from March 2020 to April 2021.

Impact of family-based selection on growth performance and immune response of Japanese quail

The present study was aimed to evaluate the growth performance and immune response of three genetic lines of Japanese quails. These lines i.e., selected for 4-week body-weight group (WBS), selected for egg number (EBS), and random-bred control (RBC), were selected for three consecutive generations from a base population of 1125 quails. In total, 2700 four-week-old quails from three selected groups were slaughtered in total of four generations (G0 to G3). Effects of selection and generations as well as their interactions were assessed for growth performance and immune response by applying a two-way analysis of variance. Significant means were compared with Duncan's Multiple Range Test. The statistical analysis showed a significant effect of selection and generations on most of the growth and immune response parameters. WBS in G3 presented significantly higher values of body weight, weight gain, and FCR than RBC and EBS. FCR was better in WBS during G3 than those of EBS and RBC. However, Livability% was highest in RBC while the lowest was noted in G3 of WBS line. Thymus% and spleen% were higher in EBS as compared to RBC and WBS. RBC presented a better B/S ratio and ND titer than those of EBS and WBS. The decreasing trend of ND titer in both lines of WBS and EBS as compared to RBC suggested a decrease in New Castle disease resistance in progressive generations of selection. It was concluded that selection for body weight and egg number has a positive impact on respective traits but negatively affects the immunity in later generations.

Morphometric measurements and carcass characteristics of Black Australorp, Naked Neck, and Rhode Island Red crossbreds under alternative production systems

The present trial explained the effect of alternative production systems on growth, morphometric and carcass traits of four different chicken genotypes. The second generation of two genotypes RNN (Rhode Island Red × Naked Neck) and BNN (Black Australorp × Naked Neck) obtained by two self-crosses (RNN × RNN = RR and BNN × BNN = BB) and two reciprocal crosses (RNN × BNN = RB and BNN × RNN = BR) were evaluated in three alternative production systems (conventional cages, enriched cages, and aviary). At the 6th week of age after sexing, a total of 600 birds, comprising 150 from each crossbred with a total of 300 pullets and 300 cockerels were divided into conventional cages, enriched cages, and aviary systems having 200 birds in each.Birds were organized into 3×4 factorial arrangements under Completely Randomized Design (3 production systems × 4 genotypes × 2 sexes × 25 birds = 600 birds). Regarding genotypes, RB and BR males showed higher (p < 0.01) carcass yield, drumstick weight, breast weight, and thigh weight than BB and RR genotypes. Females of BR genotype showed higher (p < 0.01) breast weight, thigh weight and drumstick weight. As far as production systems are concerned, higher (p < 0.01) liver weight, heart weight, breast weight, intestinal weight, drumstick weight, and thigh weight were observed in the males reared in enriched cages compared with conventional cages and aviary system. Females reared in enriched cages showed higher (p < 0.01) heart weight, breast weight, intestinal weight, drumstick weight, and thigh weight when compared with those reared in conventional cages and aviary. It is concluded that chickens (both sexes) of BR and RB genotypes had better morphological measurements and carcass traits than those of RR and BB genotype chickens. Among alternative production systems, chickens reared in enriched cages had better traits than those of reared in conventional cages and aviary during the growing phase.

Genomics, social media and mobile phone data enable mapping of SARS-CoV-2 lineages to inform health policy in Bangladesh

Genomics, combined with population mobility data, used to map importation and spatial spread of SARS-CoV-2 in high-income countries has enabled the implementation of local control measures. Here, to track the spread of SARS-CoV-2 lineages in Bangladesh at the national level, we analysed outbreak trajectory and variant emergence using genomics, Facebook 'Data for Good' and data from three mobile phone operators. We sequenced the complete genomes of 67 SARS-CoV-2 samples (collected by the IEDCR in Bangladesh between March and July 2020) and combined these data with 324 publicly available Global Initiative on Sharing All Influenza Data (GISAID) SARS-CoV-2 genomes from Bangladesh at that time. We found that most (85%) of the sequenced isolates were Pango lineage B.1.1.25 (58%), B.1.1 (19%) or B.1.36 (8%) in early-mid 2020. Bayesian time-scaled phylogenetic analysis predicted that SARS-CoV-2 first emerged during mid-February in Bangladesh, from abroad, with the first case of coronavirus disease 2019 (COVID-19) reported on 8 March 2020. At the end of March 2020, three discrete lineages expanded and spread clonally across Bangladesh. The shifting pattern of viral diversity in Bangladesh, combined with the mobility data, revealed that the mass migration of people from cities to rural areas at the end of March, followed by frequent travel between Dhaka (the capital of Bangladesh) and the rest of the country, disseminated three dominant viral lineages. Further analysis of an additional 85 genomes (November 2020 to April 2021) found that importation of variant of concern Beta (B.1.351) had occurred and that Beta had become dominant in Dhaka. Our interpretation that population mobility out of Dhaka, and travel from urban hotspots to rural areas, disseminated lineages in Bangladesh in the first wave continues to inform government policies to control national case numbers by limiting within-country travel.

Amelioration potential of Moringa oleifera extracts against sodium arsenate induced embryotoxicity and genotoxicity in mouse (Mus musculus)

Previous studies have suggested that arsenic crosses the placenta and affects the fetus development. The study under consideration aims to show comparative ameliorative effect of Moringa oleifera leaf and flower extracts against sodium arsenate induced fetus toxicity of mice. Pregnant mice (N=44) were kept in lab and divided into eleven group from (A to K) and were orally administered the doses 6 mg/kg, 12 mg/kg for sodium arsenate, 150 mg/kg and 300 mg/kg for Moringa oleifera leaf extracts (MOLE) and 150 mg/kg and 300 mg/kg for Moringa oleifera flower extracts (MOFE) comparing with control. The investigation revealed evident reduction in the fetuses weight, hind limb, fore limb, tail and snout length, crown rump and head circumferences well as malformations in tail, feet, arms, legs, skin and eyes in the negative control group (only administered with sodium arsenate). Co-administration of sodium arsenate with MOLE and MOFE ameliorate the reversed effect of sodium arsenate on the shape, length, body weight and DNA damage of fetus significantly at 95% confidence interval. However, Moringa oleifera leaf extract showed more significant results in comparison to Moringa oleifera flower extract. Hence concluded that Moringa oleifera leaf extract ameliorated the embryo toxic effects of sodium arsenate and can be used against environmental teratogens.

Effects of production system and feeding regimen on carcass and meat quality traits of Naked Neck chicken

To evaluate the effect of a production system and feeding regimen on meat quality attributes of Naked Neck chickens, a total of 150 cockerels at 18 weeks old (1625 ± 70 g) were collected from 10 treatment groups with five replicates of three birds. The factorial arrangement of treatments consisted of two production systems (intensive and free-range) and five nutritional regimens, namely 100% commercial feed; 75% commercial feed plus 25% kitchen waste; 50% commercial feed plus 50% kitchen waste; 25% commercial feed plus 75% kitchen waste; and 100% kitchen waste. Carcass traits, meat quality, and meat organoleptic were found to differ significantly among production systems, feeding regimens, and their interaction. Higher liver weight was observed in birds reared under an intensive system. Higher gizzard weight was noted in birds fed with 100% kitchen waste, whereas lower gizzard weight was observed in birds fed the commercial diet. The meat from cockerels fed with 75% kitchen waste was most yellow, whereas the meat from the birds fed with 100% kitchen waste was least yellow. At two hours after slaughter, pH of the meat was highest in birds fed 50% kitchen waste and lowest in birds fed 100% kitchen waste. The interaction of production system and feeding regimen was significant for overall acceptability score. In conclusion, Naked Neck chickens performed equally well under intensive and free-range systems, irrespective of the level of kitchen waste that they were fed.

Interspecific variations in external and internal egg quality among various captive avian species from Punjab, Pakistan

Present study was planned to determine variations in external and internal quality egg parameters of different avian species including ostrich Struthio camelus, ducks Anas platyrhynchos, chicken Gallus gallus, turkeys Meleagris gallopavo and grey francolin Francolinus pondicerinus. All the birds were kept under similar rearing conditions. A total of 150 eggs were collected for each species to record external features of these eggs. Statistically significant (p<0.05) variations were recorded in egg weight, egg length and egg width between ostrich, ducks, chicken, turkey and quail eggs. Significantly (p<0.05) higher egg weight, egg length and egg width was observed for ostrich eggs while the same was lowest for grey francolin eggs. Similarly, significantly (p<0.05) greater shape index and egg volume values were observed for ostrich eggs while lowest shape index values were recorded for turkey eggs and egg volume was lowest for grey francolin. Significantly, higher (p<0.05) values of egg density were noted for eggs of the quail and the same were lowest for ostrich eggs. Non-significant variations in egg density values were observed between eggs of the ducks, chicken, turkey and grey francolin. It has been concluded that the positive correlations between the internal and external egg quality traits indicated that the traits can be improved through selection.

Behaviour, welfare, and tibia traits of fast- and slow-growing chickens reared in intensive and free range systems

The behaviour, welfare, and tibia characteristics of fast- and slow-growing chickens were evaluated in free-range and intensive production systems. A total of 720 birds of three strains were subjected to these systems after 21 days of rearing under the same intensive environment. Each treatment was replicated six times with 20 birds in each replicate. Data were collected for welfare aspects, including feather condition, footpad, hock joint and tonic immobility, behavioural features, especially feeding or foraging, sitting, walking, scratching, pecking and dust-bathing, and tibia characteristics, including weight, length, width, medullary canal diameter and robusticity index (4 - 8 weeks). Production system had significant effects on all welfare and behaviour aspects of the birds. However, tibia characteristics were not influenced by production system, except for medullary canal diameter. The strains differed significantly in welfare, tibia characteristics and behaviour. For example, the slow-growing strains had better feather condition,  footpad and hock joint scores. Significant interactions of strain and production system were noted for all characteristics. It was recommended that Rhode Island Red chickens could be raised under either production system without compromising their welfare or causing adverse effects on leg health.

Benchmarking services in outpatient hysteroscopy (OPH): A quality improvement project

OBJECTIVE

To develop a survey evaluating women's experience of outpatient hysteroscopy (OPH) to generate data to benchmark OPH practice in the UK that can be used to optimise women's experience of OPH and improve services.

DESIGN

Quality improvement project and a population-based national survey.

SETTING

77 hospitals with outpatient hysteroscopy (OPH) services across the UK collected data over two month-period (October-November 2019).

POPULATION

5151 women attending for outpatient hysteroscopy.

METHODS

A new OPH-Patient Satisfaction Survey (OPH-PSS) was developed using a multi-disciplinary approach. Good practice guidance in hysteroscopy and existing survey's provided content for the survey. Pilot testing identified aspects of the women's OPH journey that contributed to a final survey. The final OPH-PSS was rolled out nationally to generate data for benchmarking OPH services.

MAIN OUTCOME VARIABLE

The adequacy of OPH services reflected in women's experience of their OPH journey and the quality of care being delivered.

RESULTS

The majority (3193, 76 %) of hysteroscopic procedures were recorded as diagnostic. Most (4485, 87 %) women received adequate information regarding their OPH. 4581, 89 % of women agreed that they were given an opportunity to discuss analgesia and 5033, 97 % of women felt involved in their care. As regards patient experience, although pain was reported by most women (4490, 87 %), just over half considered the degree of pain as slight. While (787, 15 %) felt pain throughout their OPH with 1 in 10 women feeling anxious. Although, 1217 (26 %) women experienced feeling faint most only felt this slightly. Overall, more than 90 % (4867) of women considered the OPH service good. The mean score rating for the overall level of care was considerably high (9.7/10). Comparative pain scores for OPH vs the worst pain felt during a menstrual period showed OPH procedures to be less painful except for endometrial ablation (P < 0.001).

CONCLUSION

This novel survey, evaluating women's experience of OPH (OPH-PSS), provides a useful tool for benchmarking performance across different OPH units. Overall, the information provided to women and their subsequent experience of OPH is good, but pain is common.

Effects of simulation for gynaecological ultrasound scan training: a systematic review

Introduction

Simulation is a potentially promising solution to some of the challenges in delivering ultrasound training, and in the last decade, research in simulation-based education has rapidly expanded. There have been no prior focused systematic reviews on the effects of simulation on gynaecological ultrasound scan training. The aim of this review was to summarise and critically appraise the available evidence.

Methods

Medline, EMBASE, CINHAL, BNI, PubMed, ERIC, Cochrane Library and ISRCTN Register of Clinical Trials were searched using selected terminology. No language restrictions were applied. The selection criteria were studies of all types that investigated the use of a simulator to teach gynaecological ultrasound. Data evaluating study outcomes, along with methodological details, were extracted in duplicate. The outcomes were classified according to the Kirkpatrick hierarchy and included: patient-related outcomes, such as discomfort; organisational efficiency outcomes, such as examination times; and trainee-related outcomes, such as competence, skill and confidence.

Results

Fourteen studies with 573 participants were included: seven randomised controlled trials, three controlled observational studies and four uncontrolled observational studies. The use of simulation practice in gynaecological ultrasound in addition to standard approaches for teaching is associated with significant improvements in competence, skill and confidence of trainees and reduced patient discomfort, increased perceived patient safety and enhanced confidence in the trainee.

Conclusion

Our findings suggest that simulation in the early stages of training in gynaecological ultrasound is beneficial for the trainee, patients and has organisational benefits through reduced examinations times and need for supervision. Future research needs to confirm these findings in the different settings.

Haplotype of receptor for advanced glycation end products is associated with arterial stiffness in essential hypertension

Background

What causes us to age has been extensively explored. The receptor for AGEs (RAGE) expression is up-regulated in atherosclerotic plaques and its activation leads to oxidative stress, cytokine and adhesion molecule formation, activation of nuclear factor-κB and cell apoptosis. We hypothesized that genetic variation in the RAGE receptor may be associated with arterial stiffness.

Methods

309 untreated hypertensive subjects were tested for genotypes of –374T&gt;A and –429T&gt;C polymorphisms with polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP). Arterial stiffness was measured as pulse wave velocity (PWV), augmentation index (AIx) and central aortic blood pressure (BP). Data was analysed using JMP Version 13 (SAS for Windows).

Results

Both polymorphisms were in Hardy-Weinberg equilibrium. The –374A A allele carriers had significantly lower aortic systolic BP (143±2 vs. 154±1, p&lt;0.001) while –429C allele carriers had lower aortic systolic BP (151±1 vs. 157±2, p&lt;0.01) compared with T carriers. –429C allele carriers had lower PWV compared to 429TT individuals (8.86±1 vs. 10.70±2.5). –374A allele carriers had lower PWV compared to 374TT individuals (9.7±1.43 vs. 10.65±2.6). Subjects with the AC haplotype had the lowest and those with the TT haplotype the highest PWV and aortic BP than any of the other haplotypes containing one or more of the at-risk alleles.

Conclusions

The combined effect of the two genotypes was additive with AA homozygotes of –374T&gt;A and C allele carriers of –429T&gt;C and the haplotype AC, associated with lowest aortic BP and arterial stiffness.

Performance of Rhode Island Red, Black Australorp, and Naked Neck crossbreds under alternative production systems

The effects of the production system, breed cross, and their interaction on performance, egg quality, and hatching traits were evaluated. Rhode Island Red and Black Australorp were crossed with Naked Neck chickens (first generation RNN, and BNN, respectively). These crosses were mated among themselves and crossed to produce four crossbreds: RR (RNN x RNN), BB (BNN x BNN), RB (RNN x BNN), and BR (BNN x RNN). Thirty-six pullets and 9 cockerels from each crossbred were maintained in three production systems: the aviary system (AV), conventional cages (CC), and enriched cages (EC). Thus there were 48 pullets and 12 cockerels in each production system. Bodyweight, egg production percentage, and egg weight were highest in EC, followed by CC and AV. Higher egg weight, egg surface area, and egg volume were also observed in EC compared with CC and AV. Fertility and hatchability were higher and early embryonic mortality was lower in AV than in EC and CC. Bodyweight, egg production percentage, egg weight, egg volume, and surface area were higher for RB and BR than for BB and RR. Fertility and hatchability were similar for RB and BR. RR was similar to BR, but lower than RB. BB had the lowest fertility and hatchability. Thus, chickens in EC performed better than in the other systems, except that hatching traits were better in AV. RB and BR performed better than BB and RR.Key words: breed crosses, chicken, egg quality, hatchability

Evaluation of three fast- and slow-growing chicken strains reared in two production environments

The present study evaluated performance, physiological response and economics of commercial fast growing (CFG), commercial slow growing (CSG), and Rhode Island Red (RIR) chickens under intensive and free-range rearing environments. After 21 days of rearing under the same intensive environment 240 birds from each strain were subjected to free-range and intensive rearing until they were 56 days old. Each treatment was replicated six times with 20 birds in each replicate. Body surface and cloacal temperatures, respiration and heart rates, feed intake, bodyweight and weight gain, feed conversion efficiency, growth efficiency, and liveability were recorded. Significant differences among strains were detected in physiological response and growth performance (except liveability). Rearing environment also caused significant differences in physiological parameters (except body surface temperature) and growth performance (except liveability). Significant interactions of the strains and production systems were detected. The CFG strain grew most rapidly under the intensive system with differences between strains being reduced in the free-range system. The RSG and CSG strains had similar respiration rates under the two production systems but differed significantly from each other. However, the CFG strain had a significantly elevated respiration rate in the free-range system. Total input cost of rearing CFG under the intensive system was highest ($3.54) among the treatments, whereas CSG under a free-range environment generated the highest profit ($0.37 per bird). In conclusion, rearing CSG under free range was the most economic farming strategy in today’s scenario.Keywords: economics, fast-growing, free range, growth, intensive system, physiology, slow-growing rural chickens

Incidence, clinical outcomes, and transmission dynamics of severe coronavirus disease 2019 in California and Washington: prospective cohort study

OBJECTIVE

To understand the epidemiology and burden of severe coronavirus disease 2019 (covid-19) during the first epidemic wave on the west coast of the United States.

DESIGN

Prospective cohort study.

SETTING

Kaiser Permanente integrated healthcare delivery systems serving populations in northern California, southern California, and Washington state.

PARTICIPANTS

1840 people with a first acute hospital admission for confirmed covid-19 by 22 April 2020, among 9 596 321 healthcare plan enrollees. Analyses of hospital length of stay and clinical outcomes included 1328 people admitted by 9 April 2020 (534 in northern California, 711 in southern California, and 83 in Washington).

MAIN OUTCOME MEASURES

Cumulative incidence of first acute hospital admission for confirmed covid-19, and subsequent probabilities of admission to an intensive care unit (ICU) and mortality, as well as duration of hospital stay and ICU stay. The effective reproduction number (RE ) describing transmission dynamics was estimated for each region.

RESULTS

As of 22 April 2020, cumulative incidences of a first acute hospital admission for covid-19 were 15.6 per 100 000 cohort members in northern California, 23.3 per 100 000 in southern California, and 14.7 per 100 000 in Washington. Accounting for censoring of incomplete hospital stays among those admitted by 9 April 2020, the estimated median duration of stay among survivors was 9.3 days (with 95% staying 0.8 to 32.9 days) and among non-survivors was 12.7 days (1.6 to 37.7 days). The censoring adjusted probability of ICU admission for male patients was 48.5% (95% confidence interval 41.8% to 56.3%) and for female patients was 32.0% (26.6% to 38.4%). For patients requiring critical care, the median duration of ICU stay was 10.6 days (with 95% staying 1.3 to 30.8 days). The censoring adjusted case fatality ratio was 23.5% (95% confidence interval 19.6% to 28.2%) among male inpatients and 14.9% (11.8% to 18.6%) among female inpatients; mortality risk increased with age for both male and female patients. Reductions in RE were identified over the study period within each region.

CONCLUSIONS

Among residents of California and Washington state enrolled in Kaiser Permanente healthcare plans who were admitted to hospital with covid-19, the probabilities of ICU admission, of long hospital stay, and of mortality were identified to be high. Incidence rates of new hospital admissions have stabilized or declined in conjunction with implementation of social distancing interventions.

Nonsurgical management of advanced hepatocellular carcinoma: a clinical practice guideline

Background

Practice guidelines based on a systematic review of the literature regarding the nonsurgical management of hepatocellular carcinoma (hcc) in North America are lacking. Resection and transplantation are the foundations for cure of hcc; however, most patients are diagnosed at an advanced stage, precluding those curative treatments. A number of local or regional therapies are used and are followed by systemic therapy for advanced or progressive disease. Other treatments are available, but their efficacy, compared with those standards, is not well known.

Methods

First, systematic review questions were developed. Literature searches of the medline, embase, and Cochrane library databases (January 2000 to July 2018 or January 2005 to July 2018 depending on the question) were conducted; in addition, abstracts from the 2018 annual meeting of the American Society of Clinical Oncology were reviewed. A practice guideline was drafted that was then scrutinized by internal and external reviewers.

Results

Seventy-seven studies were included in the guideline: no guidelines, two systematic reviews, and seventy-five primary studies published in full (including one pooled analysis). Five recommendations were developed.

Conclusions

There is no evidence for or against the use of local or regional interventions other than transarterial chemoembolization for the treatment of intermediate- or advanced-stage hcc. Furthermore, there is no evidence to support the addition of sorafenib to any local or regional therapy. Sorafenib or lenvatinib are recommended for first-line systemic treatment of intermediate-stage hcc. Regorafenib or cabozantinib provide survival benefits when given as second-line treatment. Antiviral treatment is recommended in individuals with advanced hcc who are positive for the hepatitis B surface antigen.

Association of Stress Hyper-Glycaemia on Outcomes of Hospitalized Non Diabetic Patients with First Attack of Acute ST Elevated Myocardial Infarction Underwent Thrombolysis

Coronary heart disease (CHD) is the most common cause of heart disease and serious cause of early death in developed countries around the world. Stress hyper-glycaemia has a bad prognostic implication in hospital outcomes in acute ST elevated myocardial infarction patients. It serves as a marker of myocardial damage, provides information about complications of acute MI and bad prognosis. The aim of this cross-sectional descriptive study was to find out prognostic implications of Stress hyper-glycaemia in non diabetic patients with first attack of acute ST elevated myocardial infarction underwent thrombolysis and conducted in the department of Cardiology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from June 2017 to May 2018. Total 249 first attack of Acute STEMI patients were included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group I: Patients with first attack of acute STEMI underwent thrombolysis with non diabetic stress hyper-glycaemia (Blood sugar >7.8mmol/L and HbA1c <6.5), Group II: Patients with first attack of acute STEMI underwent thrombolysis with non diabetic normo-glycaemia (Blood sugar <7.8mmol/L and HbA1c <6.5). In this study, in non diabetic Stress hyperglycemic patients' death was 5.7% and in non diabetic normo-glycemic patients death was 0.6%. It was statistically significant (p<0.05). In non diabetic stress hyperglycemic patients, heart failure was 78.31% patients and in non diabetic normo-glycemic patients, it was 21.6%. It was statistically significant (p<0.01). Echocardiography showed that patients with non diabetic Stress hyper-glycaemia had mean ejection fraction (LVEF) was 44.01±4.93 and patients with non diabetic normo-glycaemia had mean ejection fraction (LVEF) was 47.70±5.71. It was statistically significant (p<0.01). In this study, in non diabetic Stress hyperglycaemic patients, cardiogenic shock was 16.1% and in non diabetic normo-glycemic patients, it was 3.7%. It was statistically significant (p<0.05). Mean duration of hospital stay, in non diabetic Stress hyperglycaemic patients was 5.07±0.566 and in non diabetic normo-glycemic patients, it was 3.52±0.850. It was statistically significant (p<0.001). In conclusion, the incidence of death, heart failure, cardiogenic shock and hospital stay were higher in non diabetic Stress hyperglycaemic patients than non diabetic normo-glycemic patients who admitted with first attack of acute ST elevated myocardial infarction.

Mapping imported malaria in Bangladesh using parasite genetic and human mobility data

For countries aiming for malaria elimination, travel of infected individuals between endemic areas undermines local interventions. Quantifying parasite importation has therefore become a priority for national control programs. We analyzed epidemiological surveillance data, travel surveys, parasite genetic data, and anonymized mobile phone data to measure the spatial spread of malaria parasites in southeast Bangladesh. We developed a genetic mixing index to estimate the likelihood of samples being local or imported from parasite genetic data and inferred the direction and intensity of parasite flow between locations using an epidemiological model integrating the travel survey and mobile phone calling data. Our approach indicates that, contrary to dogma, frequent mixing occurs in low transmission regions in the southwest, and elimination will require interventions in addition to reducing imported infections from forested regions. Unlike risk maps generated from clinical case counts alone, therefore, our approach distinguishes areas of frequent importation as well as high transmission.
