Authors: Zheng Chuanzhen , Wang Kaixuan , Zhang Mi , Tao Qingqin , Li Xiaorong , Zhang Xiaomin
Published: November 2022

Background

The aim of this study was to report the clinical profile and outcomes of retinal pigment epithelial detachment (PED) in Vogt-Koyanagi-Harada (VKH) disease, and to evaluate the correlation between PED and the subsequent development of central serous chorioretinopathy (CSC) throughout the whole corticosteroid treatment course.

Methods

The retrospective study enrolled a total of 470 eyes with VKH, and 12 eyes with VKH and PED were recruited. Patients were divided into two groups according to the CSC onset or not throughout the whole course (the CSC group and non-CSC group). Best-corrected visual acuity (BCVA) improvement, and PED angle (PEDA, the angle between the two lines of the vertex of the lifted retinal pigment epithelium to the two edge points of the Bruch membrane) were compared between the two groups.

Results

CSC developed at the site of the PED in 5 of the 12 eyes with PED, while in the remaining 7 eyes PED gradually resolved following therapy. The prevalence of PED and CSC in VKH was 2.55% (12/470) and 1.06% (5/470), respectively. BCVA improvement in the non-CSC group was greater than that in the CSC group, but without a statistical difference (P = 0.25). PEDA was significantly smaller in the CSC group than in the non-CSC group (P = 0.03).

Conclusion

PEDA is an ideal parameter to reflect hydrostatic pressure and stretches for RPE. As PED predisposes to the development of CSC in selected VKH eyes, PEDA may be a valuable predictive factor for the development of classic CSC in VKH cases.

Authors: Chen Hongyu , Dong Le
Published: November 2022

Background

The purpose of this study was to investigate the effect of family integrated care (FICare) on the prognosis of children hospitalized with preterm infants.

Methods

Two hundred thirty preterm infants admitted to our hospital from January 2019 to April 2021 were enrolled in a prospective randomized study and divided into 115 cases in the intervention group and 115 cases in the control group according to the random number table method, and given the FICare and the conventional care, respectively. The duration of nasogastric tube retention, time to achieve total enteral nutrition, rate of weight gain, exclusive breastfeeding rate, length of hospital stay, growth and development, readmission rate, parental self-efficacy, family functioning and complications related to prematurity were compared between the two groups.

Results

Compared with the control group, the intervention group had shorter nasogastric tube retention time, shorter time to achieve total enteral nutrition, higher exclusive breastfeeding rate, shorter time of hospital stay and better growth rate. Before the intervention, there was no difference in parental self-efficacy and family functioning between the two groups; after the intervention, the intervention group had higher parental self-efficacy and higher ratings of family functioning, and the difference was statistically significant. Compared with the control group, the intervention group had a lower readmission rate and significantly lower incidence of infection and choking.

Conclusion

The FICare can shorten the time of nasogastric tube retention, shorten time to achieve total enteral nutrition and hospital stay, increase the rate of exclusive breastfeeding and the rate of weight gain, finally improve the prognosis of preterm infants and have a positive effect on parents.
Familial Hemophagocytic Lymphohistiocytosis secondary to UNC13D mutation: a report of two cases
Authors: Sadeghi Payman , Esslami Golnaz Ghazizadeh , Rokni-Zadeh Hassan , Changi-Ashtiani Majid , Mohsenipour Reihaneh
Published: November 2022

Background

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease characterized by some clinical signs (e.g., non-remitting fever, hepatosplenomegaly) and laboratory findings (e.g., cytopenia, increased ferritin level, hypofibrinogenemia, lipid disorders, coagulopathy, and multiple organ failure). Depending on the etiology, HLH is divided into familial (i.e., primary) and acquired (i.e., secondary) forms. Familial HLH (FHL), an autosomal recessive condition, is classified into five subtypes based on underlying genetic defects. The PRF1, STX11, UNC13D, HPLH1, and STXBP2 are the most well-known genes of this type which are related to granule-mediated cytotoxic T and Natural killer (NK) cells. The treatment is based on the HLH-2004 protocol.

Case presentation

The current report presents two cases of HLH with presentations different from each other and previously reported cases. Case 1 was a 15-month-old boy with fever, skin rash, splenomegaly, and bicytopenia, raised triglyceride levels, AST (aspartate transaminase), and ALT (alanine aminotransferase), normal ferritin, and abundant hemophagocytic cell in bone marrow aspiration. He was diagnosed with HLH and received HLH protocol as treatment. The patient had a homozygous intronic mutation; NM_199242: c.2448-13G > A in UNC13D. The associated disease was Familial Hemophagocytic Lymphohistiocytosis 3 (FHL3). Case 2, a 37-day-old female presented with fever, a history of neonatal cholestasis, and huge hepatosplenomegaly. Her whole-exome sequencing report manifested that the patient had the same mutation as case 1. Unfortunately, both patients passed away.

Conclusion

The sequencing of the entire UNC13D gene (coding and non-coding regions) is an applicable and valuable diagnostic procedure for the detection of deep intronic splicing variants and large inversions in patients with atypical manifestations of HLH (such as normal ferritin or triglyceride and cholesterol).
Healthcare workers’ heterogeneous mental-health responses to prolonging COVID-19 pandemic: a full year of monthly follow up in Finland
Authors: Rosenström Tom , Tuisku Katinka , Suvisaari Jaana , Pukkala Eero , Junttila Kristiina , Haravuori Henna , Elovainio Marko , Haapa Toni , Jylhä Pekka , Laukkala Tanja
Published: November 2022

Background

The COVID-19 pandemic strained healthcare workers but the individual challenges varied in relation to actual work and changes in work. We investigated changes in healthcare workers’ mental health under prolonging COVID-19 pandemic conditions, and heterogeneity in the mental-health trajectories.

Methods

A monthly survey over a full year was conducted for employees of the HUS Helsinki University Hospital (n = 4804) between 4th June 2020 to 28th May 2021. Pandemic-related potentially traumatic events (PTEs), work characteristics (e.g., contact to COVID-19 patients), local COVID-19 incidence, and demographic covariates were used to predict Mental Health Index-5 (MHI-5) and Insomnia Severity Index (ISI) in generalized multilevel and latent-class mixed model regressions.

Results

Local COVID-19 log-incidence (odds ratio, OR = 1.21, with 95% CI = 1.10–1.60), directly caring for COVID-19 patients (OR = 1.33, CI = 1.10–1.60) and PTEs (OR = 4.57, CI = 3.85–5.43) were all independently associated with psychological distress, when (additionally) adjusting for age, sex, profession, and calendar time. Effects of COVID-19 incidence on mental health were dissociable from calendar time (i.e., evolved in time) whereas those on sleep were not. Latent mental-health trajectories were characterized by a large class of “stable mental health” (62% of employees) and minority classes for “early shock, improving” (14%) and “early resilience, deteriorating” mental health (24%). The minority classes, especially “early shock, improving”, were more likely to live alone and be exposed to PTEs than the others.

Conclusions

Healthcare workers faced changing and heterogeneous mental-health challenges as the COVID-19 pandemic prolonged. Adversity and mental ill-being may have accumulated in some employees, and factors like living arrangements may have played a role. Knowledge on employees’ demographic and socioeconomic background, as well as further research on the factors affecting employees’ resilience, may help in maintaining healthy and efficient workforce in the face of a prolonging pandemic.

Published: November 2022

Background

Communication on sexual and reproductive health (SRH) between caregivers and their young adolescent children plays a significant role in shaping attitudes and behaviours that are critical to laying the foundations for positive and safe SRH behaviours in later adolescence. Nevertheless, this communication is often limited, particularly in countries where adolescent sexuality is taboo. This study assessed the topics discussed (‘level’) and the comfort of caregivers with communicating with young adolescents on SRH, and their correlates. 

Methods

A cross-sectional survey was conducted among 218 caregivers of young adolescents (10–14 years) in Mbarara district of south-western Uganda in January and February 2020. Participants were selected through consecutive sampling. A structured, pre-tested questionnaire administered by interviewers was used for data collection. The surveys were computer-assisted using Kobo Collect software. Data was exported to STATA 14 for analysis. Level of SRH communication was measured based on 10 SRH communication topics, while comfort was based on 9 SRH discussion topics. Bivariate and multivariate linear regression analyses were conducted to determine correlates of level of, and comfort with, SRH communication P-value < 0.05 was considered for statistical significance.

Results

The mean number of topics that caregivers discussed was 3.9 (SD = 2.7) out of the 10 SRH topics explored. None of the respondents discussed all the topics; 2% reported ever discussing nine topics with their young adolescent, while 3.5% reported never discussing any of the topics. General health and bodily hygiene (89.9%) and HIV/AIDS and other sexually transmitted infections (STIs) (77.5%) were the most commonly discussed, while night emissions in boys (4.3%) and condoms (8.3%) were least discussed. The majority of caregivers (62%) reported a high level of comfort with discussing SRH. The mean comfort score was 21.9 (SD = 3.8). In general, the level of SRH communication increased with an increase in comfort with SRH communication β = 0.22 (0.04); 95% CI = (0.15, 0.30). The level of comfort with SRH communication decreased with an increase in the number of YAs in a household β = -0.92 (0.38); 95%CI = (-1.66,-0.18).

Conclusion

Overall, the level of SRH communication is low and varies according to the number of SRH topics. Caregivers’ comfort with SRH communication with YAs was a significant correlate of SRH communication. This justifies the need for interventions that aim to improve caregivers’ comfort with communicating with young adolescents about SRH.
COVID-19 risk perception framework of the public: an infodemic tool for future pandemics and epidemics
Authors: Lohiniva Anna-Leena , Pensola Annika , Hyökki Suvi , Sivelä Jonas , Tammi Tuukka
Published: November 2022

Understanding the risk perceptions of the public is central for risk communications and infodemic management during emergency and preparedness planning as people’s behavior depends on how they perceive the related risks. This qualitative study aimed to identify and describe factors related to COVID-19 risk perceptions of the public in Finland and to make this information readily available to those who communicate with the public during crises. The study is part of a larger project exploring crisis narratives through a mixed-methods approach. The study was based on a dataset of over 10,000 comments on the Facebook and Twitter posts of the Finnish Institute of Health and Welfare (THL) between March-May 2021. The data were analyzed qualitatively using thematic analysis. The study identified concepts linked with the pandemic risk perception that included knowledge, perceptions, personal experiences, trust, attitudes, and cultural values. The findings resulted in a framework of risk perceptions that can be used as taxonomy and a set of key concepts and keywords in social listening to monitor risk perception during future epidemics and pandemics.
Household disinfection practices by women living in Egypt during the 2020 COVID-19 lockdown and the association of information sources and suspected bleach toxicity
Authors: Farid Maha , Talaat Rania , Pacino Valerie , Tak Hyo Jung , ElRayes Wael
Published: November 2022

Introduction

The spread of contradictory health information was a hallmark of the early COVID-19 pandemic. Because of a limited understanding of the disease, its mode of transmission, and its pathogenicity, the public turned to easily accessible and familiar sources of information. Some of these sources included wrong or incomplete information that could increase health risks and incidents of toxicity due to improper information about the usage of disinfectants. The objective of this study was to assess the relationship between sources of information about the COVID-19 pandemic, the related household cleaning and disinfection practices among adult women living in Egypt, and the associated adverse effects of bleach toxicity during a national lockdown.

Methods

Through a self-administered online survey, 452 adult women (18 years and older) living in Egypt were recruited from 13 cities between 4 June 2022 and 4 July 2022 to answer the questionnaire. The questionnaire included (41) questions in Arabic and collected data about respondents' household cleaning and disinfection practices to prevent the spread of the SARS-CoV-2 virus and protect their families during the lockdown that started in Egypt in March 2020.

Results

The study found that 88.1% (n = 398) of participants reported increased use of disinfectants during the lockdown. Women who chose social media as their primary source of information to learn about disinfection practices reported an increased frequency of respiratory symptoms associated with bleach toxicity (correlation coefficient = 0.10, p-value = 0.03), followed by women who depended on relatives and friends as the primary source of information (correlation coefficient = 0.10, p-value = 0.02).

Conclusion

This study showed that social media is an easily accessible, efficient and fast communication tool that can act as a primary source for individuals seeking medical information compared to other media platforms (e.g., websites, T.V., satellite channels). However, better regulations and monitoring of its content may help limit the harms caused by the misinformation and disinformation spread by these popular platforms, particularly in times of uncertainty and upheaval.
Temporal changes in health-related lifestyle during the COVID-19 epidemic in Finland – a series of cross-sectional surveys
Authors: Jääskeläinen Tuija , Härkänen Tommi , Haario Peppi , Isosaari Elina , Lundqvist Annamari
Published: November 2022

Background

Public health recommendations and governmental restrictions during the COVID-19 epidemic have affect everyday life. This study aimed to examine temporal changes in health-related lifestyle and the accumulation of positive and negative changes in the key lifestyle factors (vegetable consumption, leisure-time physical activity, sleeping, alcohol consumption, smoking) in the same individuals among Finnish adults during the epidemic.

Methods

This study was based on a series of cross-sectional surveys conducted between April 2020 and June 2021 to investigate antibody levels for the new coronavirus in the population. In each survey, a random sample of adults (18 to 69 years) from five university hospital regions were invited. A total of 5655 (response rate 32%) responded to the questionnaire including questions on lifestyle changes during epidemic.

Results

On average one-sixth of respondents (17%) reported at least two negative changes in the key lifestyle factors during the study period. An increase in snacking and sleep problems and decrease in leisure-time physical activity and active commuting to work were the most common of individual negative changes. The proportion of negative changes in physical activity increased as the epidemic drags on. In contrast, on average every seventh of the respondents (14%) reported at least two positive lifestyle changes in the key lifestyle factors. The most common individual positive changes were increased consumption of fruit, berries and vegetables and decreased consumption of alcohol. More negative changes were reported on average, when both negative and positive changes in the key lifestyle factors were summed. The most negative changes were reported in the late 2020.

Conclusion

The results of the present study suggest that the lifestyle changes during the COVID-19 epidemic have been diverse being on average more commonly unfavorable than favorable for health. The deteriorated epidemic situation in the late 2020 and, on the other hand, prolonged epidemic predisposed to negative lifestyle changes. Further studies are important to examine whether these changes are maintained over time and to identify the factors that contribute to changes and their accumulation in the same individuals. Health promotion actions are needed to prevent the long-term effects of the epidemic on health and welfare.

Published: November 2022

Background

The present study describes the effectiveness of a complex intervention that addresses multiple lifestyles to promote healthy behaviours in increasing adherence to the Mediterranean diet (MD). 

Methods

Cluster-randomised, hybrid clinical trial controlled with two parallel groups. The study was carried out in 26 primary Spanish healthcare centres. People aged 45–75 years who presented at least two of the following criteria were included: smoker, low adherence to the MD or insufficient level of physical activity. The intervention group (IG) had three different levels of action: individual, group, and community, with the aim of acting on the behaviours related to smoking, diet and physical activity at the same time. The individual intervention included personalised recommendations and agreements on the objectives to attain. Group sessions were adapted to the context of each healthcare centre. The community intervention was focused on the social prescription of resources and activities performed in the environment of the community of each healthcare centre. Control group (CG) received brief advice given in the usual visits to the doctor’s office. The primary outcome was the change, after 12 months, in the number of participants in each group with good adherence to the MD pattern. Secondary outcomes included the change in the total score of the MD adherence score (MEDAS) and the change in some cardiovascular risk factors.

Results

Three thousand sixty-two participants were included (IG = 1,481, CG = 1,581). Low adherence to the MD was present in 1,384 (93.5%) participants, of whom 1,233 initiated the intervention and conducted at least one individual visit with a healthcare professional. A greater increase (13.7%; 95% CI, 9.9–17.5; p < 0.001) was obtained by IG in the number of participants who reached 9 points or more (good adherence) in the MEDAS at the final visit. Moreover, the effect attributable to the intervention obtained a greater increase (0.50 points; 95% CI, 0.35 to 0.66; p < 0.001) in IG.

Conclusions

A complex intervention modelled and carried out by primary healthcare professionals, within a real clinical healthcare context, achieved a global increase in the adherence to the MD compared to the brief advice.

Menstrual hygiene practices among adolescent women in rural India: a cross-sectional study
Authors: Singh Aditya , Chakrabarty Mahashweta , Singh Shivani , Chandra Rakesh , Chowdhury Sourav , Singh Anshika
Published: November 2022

Background

Exclusive use of hygienic methods (sanitary napkins, locally prepared napkins, tampons, and menstrual cups) to prevent the visibility of bloodstains during menstruation is still considerably low among adolescent women in rural India. However, no prior research has explored the prevalence and determinants of exclusive hygienic methods among rural Indian adolescent women. To address this gap, this study examines the factors affecting adolescent women’s exclusive use of hygienic methods in rural India. Additionally, this study explores state- and district-level geographical disparities in the exclusive use of hygienic methods among adolescent women in rural India.

Methods

Information on 95,551 adolescent women from rural India from the latest round of National Family Health Survey (NFHS-5) was analyzed. Bivariate statistics and multilevel logistic regression analysis were used to assess the Individual- and community-level factors associated with exclusive use of hygienic methods among adolescent women in rural India. Choropleth maps were used to discern the geographical disparities in the exclusive use of hygienic methods.

Results

In rural India, only 42% of adolescent women exclusively used hygienic methods, with substantial geographic disparities at the state and district levels. At the state level, the exclusive use of hygienic methods varied from 23% in Uttar Pradesh to 85% in Tamil Nadu. Even greater variation was observed at the district level. There was a clear north-south divide in the exclusive use of hygienic methods among adolescent women in rural India. The results of multilevel logistic regression indicated a considerable amount of variation in the exclusive use of hygienic methods at community level which further reduced when controlled for individual and community-level factors. Rural Indian adolescent women with higher education (AOR:3.20, 95% CI: 2.81–3.64), from general category (AOR: 1.14, 95% CI: 1.07–1.21), with medium mass media exposure (AOR: 1.43, 95% CI: 1.35–1.51), and from richest wealth quintile (AOR: 3.98, 95% CI: 3.69–4.30) were more likely to use hygienic methods exclusively.

Conclusion

Wide differential across biodemographic and socioeconomic groups, and substantial geographic disparities at state- and district-level in the exclusive use of hygienic methods suggests a need to adopt context-specific interventions for adolescent women in rural India. Distribution of subsidized or free menstrual hygiene methods to disadvantaged adolescent women, and in the low-prevalence districts may increase the level of exclusive use of hygienic methods remarkably.
Diagnostic accuracy of pleural fluid lactate dehydrogenase to adenosine deaminase ratio for tuberculous pleural effusion: an analysis of two cohorts
Authors: Yan Zhi , Wen Jian-Xun , Wang Hua , Jiang Ting-Wang , Huang Jin-Hong , Chen Hong , Yan Li , Hu Zhi-De , Zheng Wen-Qi
Published: November 2022

Background

This study aimed to evaluate the diagnostic accuracy of pleural fluid (PF) lactate dehydrogenase (LDH) to adenosine deaminase (ADA) (LDH/ADA) ratio for tuberculous pleural effusion (TPE). Especially to explore whether the LDH/ADA ratio provides added diagnostic value to ADA.

Methods

The diagnostic accuracy of PF LDH/ADA ratio and ADA for TPE was evaluated in two cohorts, named the BUFF (Biomarkers for patients with Undiagnosed pleural eFFusion) cohort (62 with TPE and 194 with non-TPE) and the SIMPLE (a Study Investigating Markers in PLeural Effusion) cohort (33 with TPE and 177 with non-TPE). Receiver operating characteristic (ROC) curve and decision curve were used to measure the diagnostic accuracy of the PF LDH/ADA ratio. The added diagnostic value of the LDH/ADA ratio to ADA was evaluated with net reclassification improvement (NRI) and integrated discrimination improvement (IDI).

Results

The area under the ROC curves (AUCs) of PF ADA and LDH/ADA ratio in the BUFF cohort were 0.76 and 0.74, respectively. In the SIMPLE cohort, the AUCs of PF ADA and LDH/ADA ratio were 0.80 and 0.85, respectively. The decision curves of PF LDH/ADA and ADA were close in both the BUFF and SIMPLE cohorts. The NRI and IDI analyses did not reveal any added diagnostic value of LDH/ADA to ADA.

Conclusions

PF LDH/ADA ratio has moderate diagnostic accuracy for TPE. It does not provide added diagnostic value beyond ADA. The current evidence does not support LDH/ADA ratio for diagnosing TPE.
Tranexamic versus aminocaproic acids in patients with total hip arthroplasty: a retrospective study
Authors: Xie Hui , Yang Yu-Shen , Tian Si-miao , Wang Ben-jie , Fu Wei-min , Cheng Liang-liang , Jiang Nan-nan , Gu Guishan , Zhao De-wei
Published: November 2022

Background

Recently, tranexamic acid (TXA) and epsilon aminocaproic acid (EACA) have been applied in total hip arthroplasty (THA). However, doubts in clinicians’ minds about which medicine is more efficient and economical in THA need to be clarified. Therefore, this study compared the efficacy and cost of the intraoperative administration of TXA and EACA per surgery in decreasing perioperative blood transfusion rates in THA.

Methods

 This study enrolled patients who underwent THA between January 2019 to December 2020. A total of 295 patients were retrospectively divided to receive topical combined with intravenous TXA (n = 94), EACA (n = 97) or control (n = 104). The primary endpoints included transfusions, estimated perioperative blood loss, cost per patient and the drop in the haemoglobin and haematocrit levels.

Results

Patients who received EACA had greater total blood loss, blood transfusion rates, changes in HGB levels and mean cost of blood transfusion per patient (P < 0.05) compared with patients who received TXA. In addition, both TXA and EACA groups had significantly fewer perioperative blood loss, blood transfusion, operation time and changes in haemoglobin and haematocrit levels than the control group (P < 0.05). Cost savings in the TXA and EACA groups were 736.00 RMB and 408.00 RMB per patient, respectively.

Conclusions

The application of perioperative antifibrinolytics notably reduces the need for perioperative blood transfusions. What’s more, this study demonstrated that TXA is superior to EACA for decreasing blood loss and transfusion rates while at a lower cost per surgery. These results indicate that TXA may be the optimum antifibrinolytics for THA in Chinese area rather than EACA.
The influence of aging on the fracture load of milled monolithic crowns
Authors: Güleç Ceyda , Sarıkaya Işıl
Published: November 2022

Background

This in-vitro study was conducted to assess the effect of aging on the fracture load of molar crowns fabricated with monolithic CAD/CAM materials.

Methods

The crown restorations were produced from Cerasmart, Vita Enamic, and IPS e.max CAD blocks. Aging was applied to the 10 samples each of monolithic CAD/CAM materials (n = 10). Dual-axis chewing simulator (50 N, 1.1 Hz, lateral movement: 1 mm, mouth opening: 2 mm, 1,200,000 cycles) and thermocycling (± 5–55 °C, 6000 cycles) were applied as an aging procedure. 10 samples each of monolithic CAD/CAM materials without aging (n = 10) were considered the control group. 6 tested groups were obtained. Then, all samples were evaluated in a universal testing machine to determine the fracture loading values’.

Results

There was not a statistically significant difference between the fracture load values before and after aging for all samples of Cerasmart, Vita Enamic, and IPS e.max CAD (p > 0.005). In a comparison of the monolithic materials together, a statistically significant difference was found between the fracture load values of IPS e.max CAD and Vita Enamic crowns before aging (p = 0.02). Also, Vita Enamic crowns (1978,71 ± 364,05 N) were found different from the IPS e.max CAD (p = 0.005) and Cerasmart crowns (p = 0.041) after aging.

Conclusions

Dynamic aging with 1.200.000 cycles was found to have no effect to fracture loading on milled Cerasmart, Vita Enamic, and IPS e.max CAD monolithic crowns.
Development and evaluation of a pediatric hospital medicine board review course
Authors: Herrmann Lisa E. , Jones Yemisi O. , Kinnear Benjamin , Rule Amy , Piper Laura , Shah Samir S. , Klein Melissa
Published: November 2022

Background

The American Board of Medical Specialties recognized Pediatric Hospital Medicine (PHM) for subspecialty certification in 2016, with the first certification exam in 2019. To address the need for exam preparatory materials, we designed and evaluated a novel PHM board review course that was offered both in-person and online.

Methods

Course content was based on the American Board of Pediatrics (ABP) PHM certifying exam outline. Course objectives were developed from published PHM core competencies and the 2012 ABP general pediatrics content objectives. National experts served as faculty, presenting didactic sessions, and contributing to a question bank for high-yield review. For program evaluation, we applied the Kirkpatrick Model, evaluating estimated exam pass rates (Level 4), participant learning (Level 2) via post-presentation practice questions, and participants’ ratings of presenters (via five-point Likert scale) and satisfaction (Level 1).

Results

There were 112 in-person and 144 online participants with estimated pass rates of 89 and 93%, respectively. The mean correct response for the post-presentation knowledge questions was 84%. Faculty effectiveness ratings ranged from 3.81 to 4.96 (median score 4.60). Strengths included the pace of the course, question bank, and printed syllabus. Suggestions for improvement included question bank expansion, focus on “testable” points rather than general information, and challenges with long days of didactic presentations.

Conclusions

This novel PHM board review course demonstrated effectiveness. Hospitalists preferred focused “testable” information, an active learning environment, and a robust question bank. Future preparatory courses should consider including more opportunities for practice questions, focused content review, and learner engagement.
The association between video or telephone telemedicine visit type and orders in primary care
Authors: Juergens Nathan , Huang Jie , Gopalan Anjali , Muelly Emilie , Reed Mary
Published: November 2022

Introduction

Telemedicine is increasingly relied upon for care delivery in primary care, but the impact of visit type on clinical ordering behavior is uncertain.

Methods

Within Kaiser Permanente Northern California, we identified patients who self-scheduled and completed telemedicine encounters with their personal primary care provider or another available primary care provider in the same medical group, between April 1st, 2020, and October 31st, 2020, while physical distancing restrictions for COVID-19 were in place. We collected patient sociodemographic and clinical characteristics, measures of technology access, and categorized the most common primary encounter diagnoses. We measured proportions of patient-scheduled video versus telephone visits for each of eight diagnosis groups (Skin & Soft Tissue, Musculoskeletal Pain, Back Pain, General Gastrointestinal, Hypertension & Diabetes, Mental Health, Upper Respiratory, and Abdominal Pain), and compared physician orders for medications, antibiotics, lab and imaging studies by visit type within each diagnosis group.

Results

There were 273,301 included encounters, with 86,676 (41.5%) video visits and 122,051 (58.5%) telephone visits. Of the diagnosis groups, Skin & Soft Tissue conditions had the highest proportion of video visits (59.7%), while Mental Health conditions had the highest proportion of telephone visits (71.1%). After adjusting for covariates, the overall rates of medication orders (46.6% vs. 44.5%), imaging orders (17.3% vs. 14.9%), lab orders (19.5% vs. 17.2%), and antibiotic orders (7.5% vs. 5.2%) were higher during video visits as compared to telephone visits (p < 0.05). The largest difference within diagnosis groups was for Skin & Soft Tissue conditions, where the rate of medication orders was 9.1% higher than during video visits than telephone visits (45.5% vs. 36.5%, p < 0.05).

Conclusions

We observed statistically significant differences in clinician orders by visit type during telemedicine encounters for common primary care conditions. Our findings suggest that, for certain conditions, visual information conveyed during video visits may promote clinical work-up and treatment.
Effect of COVID-19 on the implementation of a multifaceted intervention to improve teamwork and quality for hospitalized patients: a qualitative interview study
Authors: Terwilliger Iva A. , Manojlovich Milisa , Johnson Julie K. , Williams Mark V. , O’Leary Kevin J.
Published: November 2022

Background

Healthcare organizations made major adjustments to deliver care during the COVID pandemic, yet little is known about how these adjustments shaped ongoing quality and safety improvement efforts. We aimed to understand how COVID affected four U.S. hospitals’ prospective implementation efforts in an ongoing quality improvement initiative, the REdesigning SystEms to Improve Teamwork and Quality for Hospitalized Patients (RESET) project, which implemented complementary interventions to redesign systems of care for medical patients.

Methods

We conducted individual semi-structured interviews with 40 healthcare professionals to determine how COVID influenced RESET implementation. We used conventional qualitative content analysis to inductively code transcripts and identify themes in MAXQDA 2020.

Results

We identified three overarching themes and nine sub-themes. The three themes were (1) COVID exacerbated existing problems and created new ones. (2) RESET and other quality improvement efforts were not the priority during the pandemic. (3) Fidelity of RESET implementation regressed.

Conclusion

COVID had a profound impact on the implementation of a multifaceted intervention to improve quality and teamwork in four hospitals. Notably, COVID led to a diversion of attention and effort away from quality improvement efforts, like RESET, and sites varied in their ability to renew efforts over time. Our findings help explain how COVID adversely affected hospitals’ quality improvement efforts throughout the pandemic and support the need for research to identify elements important for fostering hospital resilience.

Authors: Kim Kyoung-A , Lee Jungeun , Kim Dahee , Min Deulle
Published: November 2022

Background

An increase in the number of older adults has highlighted the important issue of the safety of residents in nursing homes. This review aimed to review previous studies on patient safety of older adults living in nursing homes, analyze the tools used to measure it, and identify factors affecting patient safety of older adult residents in nursing homes.

Methods

A literature search was conducted using EMBASE, PubMed, CINHAL, and COCHRANE. The main search terms were “nursing home” or “skilled nursing facility” or “long-term care facility” and “patient safety.” In total, 13,586 articles were identified. Two authors independently assessed the quality of each selected study using the Crowe Critical Appraisal Tool.

Results

Twenty-five studies were included in the analysis. There were a total of seven tools used to measure patient safety in nursing homes: the Nursing Home Survey on Patient Safety Culture (10 studies) and Hospital Survey on Patient Safety Culture (nine studies). Furthermore, the Nursing Home Survey on Patient Safety Culture-China, Safety Attitudes Questionnaire, Safety Attitudes Questionnaire in a Skilled Nursing Facility, Safety Attitudes Questionnaire-Ambulatory Version, and Modified Stanford Patient Safety Culture Survey Instrument were used in one study each. The most used tool among them was the Nursing Home Survey on Patient Safety Culture. Most tools used to measure patient safety in nursing homes were related to patient safety culture and employee attitudes.

Conclusion

Organizational factors, such as the staff education system and the composition of appropriate personnel, should be strengthened to establish a patient safety culture in nursing homes, for which policy support is crucial.

Published: November 2022

Background

The role of the sputum microbiome in chronic obstructive pulmonary disease (COPD) progression remains elusive. As the advent of the new culture-independent microbial sequencing technique makes it possible to disclose the complex microbiome community of the respiratory tract. The aim of this study was to use metagenomic next-generation sequencing (mNGS) to confirm whether there are differences in sputum microbiome of COPD between different exacerbation frequencies and lung function.

Methods

Thirty-nine COPD patients were divided into a frequent exacerbators (FE) group (n = 20) and a non-frequent exacerbators (NFE) (n = 19) group according to their exacerbation history, or a mild group (FEV1/pre ≥ 50%, n = 20) and a severe group (FEV1/pre < 50%, n = 19) according to the lung function. Sputum was collected during their stable phase, followed by DNA extraction, untargeted metagenomic next-generation sequencing (mNGS) and bioinformatic analysis.

Results

mNGS identified 3355 bacteria, 71 viruses and 22 fungi at the specie level. It was found that Shannon index and Simpson index in FE group was lower than that in NFE group (p = 0.005, 0.008, respectively) but similar between mild and severe groups. Out of top 10 bacteria taxa, Veillonella, Fusobacterium and Prevotella jejuni had a higher abundance in NFE group, Rothia had a higher abundance in mild group. Linear discriminant analysis revealed that many bacterial taxa were more abundant in NFE group, and they mostly belonged to Actinobacteria, Bacteroidetes and Fusobacteria phyla. Frequency of exacerbations was also found to be negatively correlated with alpha diversity (with Shannon index, r = − 0.423, p = 0.009; with Simpson index, r = − 0.482, p = 0.002). No significant correlation was observed between alpha diversity and FEV1/pre.

Conclusions

Microbiome diversity in FE group was lower than that in NFE group. There was a significant difference in microbiome taxa abundance between FE and NFE groups, or mild and severe groups. These findings demonstrated that sputum microbiome community dysbiosis was associated with different exacerbation frequencies and lung function in stable COPD.

Published: November 2022

Background

COVID-19 related acute respiratory distress syndrome (ARDS) has specific characteristics compared to ARDS in other populations. Proning is recommended by analogy with other forms of ARDS, but few data are available regarding its physiological effects in this population. This study aimed to assess the effects of proning on oxygenation parameters (PaO2/FiO2 and alveolo-arterial gradient (Aa-gradient)), blood gas analysis, ventilatory ratio (VR), respiratory system compliance (CRS) and estimated dead space fraction (VD/VT HB). We also looked for variables associated with treatment failure.

Methods

Retrospective monocentric study of intubated COVID-19 ARDS patients managed with an early intubation, low to moderate positive end-expiratory pressure and early proning strategy hospitalized from March 6 to April 30 2020. Blood gas analysis, PaO2/FiO2, Aa-gradient, VR, CRS and VD/VT HB were compared before and at the end of each proning session with paired t-tests or Wilcoxon tests (p < 0.05 considered as significant). Proportions were assessed using Fischer exact test or Chi square test.

Results

Forty-two patients were included for a total of 191 proning sessions, median duration of 16 (5–36) hours. Considering all sessions, PaO2/FiO2 increased (180 [148–210] vs 107 [90–129] mmHg, p < 0.001) and Aa-gradient decreased (127 [92–176] vs 275 [211–334] mmHg, p < 0.001) with proning. CRS (36.2 [30.0–41.8] vs 32.2 [27.5–40.9] ml/cmH2O, p = 0.003), VR (2.4 [2.0–2.9] vs 2.3 [1.9–2.8], p = 0.028) and VD/VT HB (0.72 [0.67–0.76] vs 0.71 [0.65–0.76], p = 0.022) slightly increased. Considering the first proning session, PaO2/FiO2 increased (186 [165–215] vs 104 [94–126] mmHg, p < 0.001) and Aa-gradient decreased (121 [89–160] vs 276 [238–321] mmHg, p < 0.001), while CRS, VR and VD/VT HB were unchanged. Similar variations were observed during the subsequent proning sessions. Among the patients who experienced treatment failure (defined as ICU death or need for extracorporeal membrane oxygenation), fewer expressed a positive response in terms of oxygenation (defined as increase of more than 20% in PaO2/FiO2) to the first proning (67 vs 97%, p = 0.020).

Conclusion

Proning in COVID-19 ARDS intubated patients led to an increase in PaO2/FiO2 and a decrease in Aa-gradient if we consider all the sessions together, the first one or the 4 subsequent sessions independently. When considering all sessions, CRS increased and VR and VD/VT HB only slightly increased.

Published: November 2022

Galectins are β-galactoside-binding proteins that bind and crosslink molecules via their sugar moieties, forming signaling and adhesion networks involved in cellular communication, differentiation, migration, and survival. Galectins are expressed ubiquitously across immune cells, and their function varies with their tissue-specific and subcellular location. Particularly galectin-1, -3, and -9 are highly expressed by inflammatory cells and are involved in the modulation of several innate and adaptive immune responses. Modulation in the expression of these proteins accompany major processes in cardiovascular diseases and metabolic disorders, such as atherosclerosis, thrombosis, obesity, and diabetes, making them attractive therapeutic targets. In this review we consider the broad cellular activities ascribed to galectin-1, -3, and -9, highlighting those linked to the progression of different inflammatory driven pathologies in the context of cardiovascular and metabolic disease, to better understand their mechanism of action and provide new insights into the design of novel therapeutic strategies.

Authors: Zhang Xiao-Tong , Ge Nan , Xiang Zi-Jian , Liu Tao
Published: November 2022

Background

Although people are more and more aware of the cardiotoxicity caused by immune checkpoint inhibitors (ICIs) in the treatment of lung cancer, its incidence rate has not been systematically analyzed. This study aims to evaluate the incidence of cardiotoxicity related to the ICI therapies for lung cancer, so as to enhance clinicians' attention to cardiotoxicity, implement proper prevention and intervention for high-risk patients, and minimize the risk of cardiac dysfunction during and after completion of therapy.

Methods

We conducted a systematic literature search for relevant publications in PubMed and Scopus from inception to 19 April 2022. Pooled incidence and risk ratios with 95% confidence intervals (95% CIs) for cardiotoxicity events were calculated.

Results

A total of 37 studies covering 38 trials, including 14,342 patients, were identified. The pooled risk ratios of incidence of any cardiac AEs were 1.944 [95% CI 0.8–4.725] (Single ICI versus chemotherapy), 1.677 [95% CI 1.065–2.64] (Single ICI plus chemotherapy versus chemotherapy), and 0.478 [95% CI 0.127–1.798] (Single ICI versus Dual ICI). The incidence of myocarditis and arrhythmia were 0.003[95%CI 0.002–0.006] and 0.014[95%CI 0–0.037], respectively.

Conclusion

Single ICI did not increase the risk of cardiotoxicity compared with chemotherapy, and single ICI plus chemotherapy increased the risk of cardiotoxicity by 67% compared with chemotherapy alone. Combination immunotherapy did not increase the risk of cardiotoxicity compared with single ICI.

Published: November 2022

Gynecological cancer is one of the most severe diseases that threaten the lives and health of women worldwide. Its incidence rate increases with each passing year and becomes more prevalent among young people. The prognosis of gynecological cancer remains poor despite significant advances in surgical removal and systemic chemotherapy. Several chemokines play a role in the progression of gynecologic cancers. CCL2 (CC-chemokine ligand 2), also termed MCP-1 (monocyte chemotactic protein 1), plays a significant physiological role in monocyte cell migration and the inflammatory response. Recent studies have demonstrated that CCL2 plays a pro-tumorigenic function in the tumor microenvironment. According to previous studies, CCL2 plays a significant role in the occurrence and development of gynecological cancers. Furthermore, recent studies noted that CCL2 could be a potential diagnostic biomarker and prognostic predictor. The purpose of this paper is to review the role of CCL2 in the occurrence and development of gynecological cancers and to discuss the potential therapeutic strategy of CCL2 for gynecological cancers, with a primary focus on breast cancer, ovarian cancer, cervical cancer, and endometrial cancer.
