Abstract
Background
Mounting evidence supports associations between objective neighborhood disorder, perceived neighborhood disorder, and health, yet alternative explanations involving socioeconomic and neighborhood social cohesion have been understudied. We tested pathways between objective and perceived neighborhood disorder, perceived neighborhood social cohesion, and socioeconomic factors within a longitudinal cohort.

Methods
Demographic and socioeconomic information before diagnosis was obtained at interviews conducted approximately 10 months post-diagnosis from participants in the Women’s Circle of Health Follow-up Study – a cohort of breast cancer survivors self-identifying as African American or Black women (n = 310). Neighborhood perceptions were obtained during follow-up interviews conducted approximately 24 months after diagnosis. Objective neighborhood disorder was from 9 items audited across 23,276 locations using Google Street View and scored to estimate disorder values at each participant’s residential address at diagnosis. Census tract socioeconomic and demographic composition covariates were from the 2010 U.S. Census and American Community Survey. Pathways to perceived neighborhood disorder were built using structural equation modelling. Model fit was assessed from the comparative fit index and root mean square error approximation and associations were reported as standardized coefficients and 95% confidence intervals.

Results
Higher perceived neighborhood disorder was associated with higher objective neighborhood disorder (β = 0.20, 95% CI: 0.06, 0.33), lower neighborhood social cohesion, and lower individual-level socioeconomic factors (final model root mean square error approximation 0.043 (90% CI: 0.013, 0.068)). Perceived neighborhood social cohesion was associated with individual-level socioeconomic factors and objective neighborhood disorder (β = − 0.11, 95% CI: − 0.24, 0.02).

Conclusion
Objective neighborhood disorder might be related to perceived disorder directly and indirectly through perceptions of neighborhood social cohesion.

AbstractBackgroundThe research aimed to formulate and test a model concerning COVID-19 perceptions effects on job insecurity and a set of psychosocial factors comprising anxiety, depression, job burnout and job alienation in the Middle East and North African (hereafter, MENA) regional context. Also, the study attempted to examine whether locus of control can moderate these hypothesised linkages amongst customer service employees working in MENA hospitality organisations.MethodsThe study is based on a sample of 885 responses to an online survey and Partial Least Square Structural Equation Modelling (PLS-SEM).ResultsThe main findings show the existence of a significant correlation between COVID perceptions and job insecurity and all psychosocial factors, i.e., more intense COVID-19 perceptions accompany higher levels of job insecurity, anxiety, depression, job burnout and job alienation. Furthermore, our results revealed that, in pandemic time, hospitality customer service employees with external locus of control are more likely to suffer higher alienation, anxiety and depression than those with internal locus of control.ConclusionsThe research originality centres on the establishment that COVID-19 has a severe negative impact within the hospitality customer service labour force (in the MENA region). These effects were more profound for participants who claimed external locus of control than those with internal locus of control.

Published: November 2021

Abstract
Background
Few studies have reported the prevalence of metabolic syndrome (MS) and examined relationships between socioeconomic status and MS in rural China. This study aimed to evaluate the prevalence of MS and MS components as well as their associations with socioeconomic status among rural Chinese adults.

Methods
A cross-sectional study of 26,836 participants aged 20 years and older was conducted from June to December 2012 in Yuhuan City, Zhejiang Province, China, which is located on Yuhuan Island. A multivariable logistic regression model was used to identify risk factors for MS and their possible interactions.

Results
Among 26,836 subjects with an average age of 53.4 ± 14.0 years, 59% were female. The overall prevalence of MS was 20.5%, and there was a significant sex difference in the prevalence (15.1% for males vs. 24.2% for females, P < 0.001). Compared with males, females also showed a significantly higher proportion of most MS components. A significantly higher prevalence of MS was found among subjects who were elderly, had a lower income level, had a lower level of education, or were unemployed. Multiple significant interactions were observed between the prevalence of MS and sex, age or socioeconomic status (P < 0.001). The risk of MS increased significantly with age in females but not in males. Additionally, a lower income level and a lower level of education were significantly related to an increased risk only in females, and unemployed males had a higher risk of MS than unemployed females.

Conclusions
The prevalence of MS and its components was relatively high in a rural island Chinese population with rapid urbanization, and sex-specific associations between socioeconomic factors and MS were found. Targeted preventive interventions should be developed and implemented to prevent and control MS among those with low socioeconomic status, especially females.

Abstract
Background
We have reported that heparin-binding epidermal growth factor (HB-EGF) is increased in patients with chronic obstructive pulmonary disease (COPD) and associated with collagen deposition, but the mechanisms remain unclear. In the present study, we aimed to investigated the inflammatory cytokines secreted by bronchial epithelial cells following exposure to HB-EGF that promoted proliferation and migration of human lung fibroblast.

Methods
HB-EGF–induced inflammatory cytokines were assayed in two airway epithelial cells (primary human bronchial epithelial cells [HBECs] and BEAS-2B cells). Moreover, the culture supernatants derived from HB-EGF-treated HBECs and BEAS-2B cells were added to human primary lung fibroblasts. The effect of culture supernatants on proliferation and migration of fibroblasts was assessed.

Results
IL-8 expression was significantly increased in bronchial epithelial cells treated with HB-EGF, which was at least partially dependent on NF-kB pathways activation. HB-EGF–induced IL-8 was found to further promote lung fibroblasts proliferation and migration, and the effects were attenuated after neutralizing IL-8.

Conclusions
These findings suggest that HB-EGF may be involved in the pathology of airway fibrosis by induction of IL-8 from airway epithelium, subsequently causing lung fibroblasts proliferation and migration. Thus, inhibition of HBEGF and/or IL-8 production could prevent the development of airway fibrosis by modulating fibroblast activation.

Published: November 2021

Abstract
Background
Postoperative complications continue to constitute a major issue for both the healthcare system and the individual patient and are associated with inferior outcomes and higher healthcare costs. The objective of this study was to evaluate the trends of postoperative complication rates over a 7-year period.

Methods
The NSQIP datasets from 2012 to 2018 were used to assess 30-day complication incidence rates including mortality rate following surgical procedures within ten surgical subspecialties. Multivariable logistic regression was used to associate complication rates with dataset year, while adjusting for relevant confounders.

Results
A total of 5,880,829 patients undergoing major surgery were included. Particularly the incidence rates of four complications were found to be decreasing: superficial SSI (1.9 to 1.3%), deep SSI (0.6 to 0.4%), urinary tract infection (1.6 to 1.2%) and patient unplanned return to the operating room (3.1 to 2.7%). Incidence rate for organ/space SSI exhibited an increase (1.1 to 1.5%). When adjusted, regression analyses indicated decreased odds ratios (OR) through the study period years for particularly deep SSI OR 0.92 [0.92–0.93], superficial SSI OR 0.94 [0.94–0.94] and acute renal failure OR 0.96 [0.95–0.96] as the predictor variable (study year) increased (p < 0.01). However, OR’s for organ/space SSI 1.05 [1.05–1.06], myocardial infarction 1.01 [1.01–1.02] and sepsis 1.01 [1.01–1.02] increased slightly over time (all p < 0.01).

Conclusions
Incidence rates for the complications exhibited a stable trend over the study period, with minor in or decreases observed.
Three-channel ion chromatograph for improved metabolic evaluation of urolithiasis
Authors: Li Qiang , Liu Guanlin , Cheng Yue , Tang Wenbo 
Published: November 2021

Abstract
Background
Urolithiasis is a multi-etiological disease resulting from a combination of environmental and genetic factors. One of the most challenging aspects of this disease is its high recurrence rate. For most patients, an in-depth metabolic evaluation may reveal the presence of urinary stones. The fact that different urinary stone-related compounds (USRCs) are measured by different methods renders the metabolic evaluation of urolithiasis quite tedious and complex.

Methods
A three-channel ion chromatograph (IC) that automatically measures the concentration of common metabolic indicators of urolithiasis in urine (i.e., oxalate, citrate, uric acid, calcium, and magnesium) was developed to improve the efficiency. To validate its precision and specificity, standard curves were prepared using working solution of these indicators. 100 standard solutions of these indicators were measured with our new IC and three other ICs as the control instruments; analyte concentrations in 100 24-h urine samples from volunteers and 135 calculi patients were also measured.

Results
All analytes had good linear relationships in concentration ranges of 0–10 mg/L. The precision experiments in the standard and urine samples showed that the measurement errors of the newly developed IC were all less than 5%. In urine, the recovery rate ranged from 99.6 to 100.4%, the coefficient of variation ranged from 1.39 to 2.99%, and the results matched between our newly developed IC and the control ICs. The results of the efficiency test showed that we can finish the analysis at the average number of 14 people per day with the new IC. While the average number in the control group is 3.85/day (p = 0.000).

Conclusions
Overall, this multi-channel system significantly improves the efficiency of metabolic evaluation while retaining accuracy and precision.
Commentary in response to BMC Urology publication entitled “Infection-related hospitalization following ureteroscopic stone treatment: results from a surgical collaborative”
Authors: Mayer Wesley A. 
Published: November 2021

AbstractThis Commentary is in response to the BMC Urology publication entitled “Infection-related hospitalization following ureteroscopic stone treatment: Results from a surgical collaborative”. This study utilized a registry with prospectively recorded standardized data elements named Reducing Operative Complications from Kidney Stones, part of the Michigan Urological Surgery Improvement Collaborative, to identify risk factors of infection-related hospitalization after ureteroscopy for stone treatment. The study included 1817 primary URS procedures for urinary stones in 11 practices in Michigan. They found 43 patients (2.4%) were hospitalized with an infection-related complication and 3 patients died during their hospitalization (0.2% mortality rate). Just over 20% of patients did not have a pre-operative urinalysis or urine culture, representing a deviation from guideline recommendations. Also, in the hospitalized group, none of the 12 patients (27.9%) who had a positive pre-operative urinalysis or urine culture received pre-operative treatment. A multivariable analysis identified higher Charleston Comorbidity Index, history of recurrent urinary tract infection, increasing stone size, intraoperative complications, and fragments left in-situ as independent risk factors for hospitalization from an infection after ureteroscopy. This commentary discusses caveats to the data as well as short-comings of the study. It also reviews more broadly infection after ureteroscopy, includes findings from similar studies, and highlights guideline recommendations to reduce infection risk.

Abstract
Background
Unsafe abortion is a leading cause of maternal mortality. In Afghanistan, which has experienced decades of armed conflict and where abortion is highly restricted, maternal mortality is high at 638 maternal deaths per 100,000 live births. Post-abortion care (PAC) is a lifesaving package of interventions to reduce morbidity and mortality related to induced or spontaneous abortion, but is rarely provided and often of poor quality, particularly in humanitarian settings. In July 2018, we conducted a study to identify the factors that influence access to and use of PAC services at Sharana Provincial Hospital.

Methods
In-depth interviews (IDIs) were conducted with ten women who had received PAC services at Sharana Hospital, and eight focus group discussions (FGDs) were conducted with 40 married women and 40 married men aged 18–45 from four villages surrounding Sharana Hospital.

Results
PAC clients and community participants discussed similar barriers to seeking PAC, including cost, distance to the health facility, the need for male accompaniment to seek care, perceived and actual quality of care, stigma and shame. Despite the mentioned stigma around abortion, community members expressed willingness to help women to receive PAC.

Conclusions
Our results suggest that while some barriers are not unique to PAC, others, especially those related to stigma around abortion, may be specific to PAC. It is important for the Ministry of Public Health and its partners to prioritize addressing these barriers to ensure that women have access to this critical life-saving care.
Improving preoperative breast reconstruction consultations: a qualitative study on the impact of personalised audio-recordings
Authors: Petric Josipa , Sadri Bahara , van Essen Phillipa , Dean Nicola Ruth 
Published: November 2021

Abstract
Background
To investigate the value of audio-recordings in aiding patient understanding and recall of preoperative breast reconstruction information.

Methods
This was a prospective cohort study. Participants were randomly allocated into either a recording group who were offered the opportunity to record their breast reconstruction explanation of surgery, or a standard information package group who received standard care. The value of having an audio-recording was assessed by semi-structured interviews and analysis of recurring themes.

Results
Between 21/2/19 and 19/3/20, 32 women attending consultations for breast reconstruction consented to participate in the study, 17 were randomly assigned to the recording group and 15 the standard information package group. Twenty-eight of the 32 participants completed qualitative interviews. All participants agreed that audio-recordings were a beneficial resource which allowed them to have a better understanding of the concepts discussed. Commonly reported themes included the ability to listen to the recording multiple times to refresh memory, as well as usefulness in helping to inform other family members. Participants also reported increased levels of trust in their clinician for allowing the audio-recordings. Very few participants raised any medico-legal implications of the recordings, their focus was more on the potential of the audio-recordings to alleviate the overwhelming nature of a pre-operative breast reconstruction consultation.

Conclusions
There was a positive response from participants to the use of audio-recordings in the setting of breast reconstruction consultations. These types of recordings could potentially be used in other complex appointments where detailed information is discussed, with similar success.
Governance frameworks for COVID-19 research ethics review and oversight in Latin America: an exploratory study
Authors: Palmero Ana , Carracedo Sarah , Cabrera Noelia , Bianchini Alahí 
Published: November 2021

Abstract
Background
Research has been an essential part of the COVID-19 pandemic response, including in Latin American (LA) countries. However, implementing research in emergency settings poses the challenge of producing valuable knowledge rapidly while upholding research ethical standards. Research ethics committees (RECs) therefore must conduct timely and rigorous ethics reviews and oversight of COVID-19 research. In the LA region, there is limited knowledge on how countries have responded to this need. To address this gap, the objective of our project is to explore if LA countries developed policies to streamline ethics review and oversight of research in response to the pandemic while ensuring its adherence to ethical standards, and to analyze to what extent these governance frameworks are in accordance with international guidance.

Methods
We conducted a descriptive and exploratory study assessing the COVID-19 research ethics governance frameworks of 19 LA countries, considering 4 dimensions based on international COVID-19 ethics guidance documents: (i) ethics review organizational model adopted, (ii) measures to coordinate between RECs and other research stakeholders, (iii) operational guidance for RECs, and (iv) key ethical issues for review and oversight of COVID-19 research.

Results
10 out of 19 LA countries have some policy to streamline ethics review of COVID-19 research. Of these countries only 6 issued comprehensive documents following international guidance that contemplate strategies with recommendations for concrete actions for a timely and rigorous review.

Conclusion
LA countries adopted partial strategies and operational guidance that may demonstrate a lack of a comprehensive view of research ethics for the review and oversight of COVID-19 research. Continuing efforts should be directed to strengthen LA countries' research capacity to respond timely and ethically to future health emergencies. Past lessons and the ones from this pandemic should be the basis to develop international standards and operational guidelines for ethics review and oversight of any research for public health emergencies.
Improving nurses’ knowledge, attitude, and performance in relation to ethical codes through group reflection strategy

Published: November 2021

Abstract
Background
The most basic responsibility of nurses that even precedes their therapeutic role is respect for professional ethics in providing clinical care. The present study was conducted to determine the effect of group reflection on the knowledge, attitude and performance of nurses in relation to ethical codes.

Methods
The present blinded, before-after, educational trial was conducted on 86 nurses working at a general hospital in the south of Iran who were randomly divided into a intervention (n = 44) and a control (n = 42) group. Data were collected before and after the intervention using three tools, including a knowledge test, an attitude rating scale and a performance questionnaire. In the intervention group, the intervention given consisted of four sessions of group reflection, and the control group received a single lecture on ethical codes.

Results
The mean changes in the nurses’ score of knowledge after the intervention compared to before differed significantly in both intervention and control groups (P < 0.001), but there was no significant difference between the two groups in terms of the mean changes in the score of knowledge (2.73 ± 3.45 in intervention group vs. 2.57 ± 3.36 in control group, P = 0.83). Although the mean score of attitude differed significantly between the intervention and control groups in the posttest (34.7 ± 8.44 in intervention group vs. 29.95 ± 9.09 in control group, P < 0.014), the two groups were not significantly different in terms of the mean changes in the score of attitude in relation to ethical codes before and after the intervention (P < 0.14). Moreover, the two groups were significantly different in terms of the mean changes in the scores of performance in the two stages (9.07 ± 16.84 in intervention group vs. 0.67 ± 20.01 in control group, P < 0.001).

Conclusion
Group reflection can improve the knowledge, attitude and performance of nurses in relation to ethical codes. Although lectures can help improve nurses’ knowledge and attitude in this area, they have no significant effects on their performance.
