Published: November 2022

Background

Older adults with cognitive impairment are frequently hospitalized and discharged to facility-based transitional care programs (TCPs). However, it is unknown whether TCPs are effective in improving their functional status and promoting discharge home rather than to long-term care. The aims of this systematic review were to examine the effectiveness of facility-based TCPs on functional status, patient and health services outcomes for older adults (≥ 65 years) with cognitive impairment and to determine what proportion post TCP are discharged home compared to long-term care.

Methods

The Joanna Briggs Institute Critical Appraisal Manual for Evidence Synthesis was used to guide the methodology for this review. The protocol was published in PROSPERO (registration number CRD42021257870). MEDLINE, CINAHL, PsycINFO, the Cochrane Library, and EMBASE databases, and ClinicalTrials.gov and the World Health Organization Trials Registry were searched for English publications. Studies that met the following criteria were included: community-dwelling older adults ≥ 65 years who participated in facility-based TCPs and included functional status and/or discharge destination outcomes. Studies with participants from nursing homes and involved rehabilitation programs or transitional care in the home or in acute care, were excluded. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklists. Results are in narrative form.

Results

Twenty-two studies (18 cohort and four cross sectional studies) involving 4,013,935 participants met inclusion criteria. The quality of the studies was mostly moderate to good. Improvement in activities of daily living (ADLs) was reported in eight of 13 studies. Between 24.4%-68% of participants were discharged home, 20–43.9% were hospitalized, and 4.1–40% transitioned to long-term care. Review limitations included the inability to perform meta-analysis due to heterogeneity of outcome measurement tools, measurement times, and patient populations.

Conclusions

Facility-based TCPs are associated with improvements in ADLs and generally result in a greater percentage of participants with cognitive impairment going home rather than to long-term care. However, gains in function were not as great as for those without cognitive impairment. Future research should employ consistent outcome measurement tools to facilitate meta-analyses. The level of evidence is level III-2 according to the National Health and Medical Research Council for cohort and cross-sectional studies.

Authors: Mellow Maddison L. , Hull Melissa J. , Smith Ashleigh E. , Wycherley Thomas P. , Girard Danielle , Crozier Alyson J.
Published: November 2022

Background

Although the health benefits of physical activity are well documented, most older adults are not sufficiently active. There is a need to explore approaches to physical activity promotion amongst older adults that meet the personal preferences and needs of participants, and that can be implemented on a large scale in community-based settings. The current study evaluates Daily Moves, a community-based physical activity program for older adults living in Adelaide, Australia. 

Methods

The Daily Moves program, which ran almost entirely during the COVID-19 pandemic, provided participants with personalized plans and information about suitable physical activity promoting activities available in their local area. This study used an explanatory sequential mixed-methods approach to evaluate associations between participation in the Daily Moves program and physical activity engagement, physical function and psychosocial wellbeing, and to explore the experiences of Daily Moves participants through qualitative interviews, with a particular focus on the impact of the COVID-19 pandemic on program participation and enjoyment.

Results

The research evaluation included 69 older adults (mean age at baseline = 73.9 ± 5.6 years; 19 male). Following Daily Moves, participants reported an increase in self-report physical activity levels (mean increase = 1.8 days, p < 0.001), improvements on several measures of physical function (left grip strength (mean increase = 1.8 kg, p < 0.001); right grip strength (mean increase = 1.3 kg, p = 0.03); Timed Up and Go (mean decrease = 1.3 s, p < 0.001)), and no significant changes in measures of psychosocial wellbeing. Qualitative interviews revealed that participants valued the supportive and flexible nature of Daily Moves, and that they felt connected with staff and other participants despite the onset of the pandemic.

Conclusions

This evaluation demonstrates that physical activity programs embedded within the community can provide flexible and tailored recommendations to participants, and that this approach can promote positive change in important indicators of health in older adults.

Published: November 2022

Background

Peritoneal dialysis (PD) is an effective and successful renal replacement therapy. The baseline peritoneal solute transfer rate (PSTR) is related to local membrane inflammation and may be partially genetically determined. Herein, we focused on vascular endothelial growth factor (VEGF) and its receptor, kinase insert domain containing receptor (KDR).

Methods

This study recruited 200 PD patients from Renji Hospital in Shanghai, China. We analysed the association between the polymorphisms of VEGF and KDR and the 4-hour dialysate-to-plasma ratio for creatinine (4 h D/P Cr), which was measured between one and three months after initiating PD.

Results

The CC genotype in VEGF rs3025039 and the AA genotype in KDR rs2071559 were both positively associated with a fast baseline PSTR (VEGF rs3025039 CC vs. TT + TC: 0.65 ± 0.12 vs. 0.61 ± 0.11; P = 0.029; KDR rs2071559 AA vs. GA + GG: 0.65 ± 0.12 vs. 0.62 ± 0.12; P = 0.039).

Conclusion

Baseline PSTR was partly determined by VEGF and KDR gene polymorphisms.
Anti-NMDAR encephalitis with GFAPα IgG: a case report
Authors: Bai Peng , Liu Bin , Li Min , Chun Mei , Ma Xiangling , Zhen Jin
Published: November 2022

Background

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an inflammatory disease of the central nervous system (CNS) in which antibodies within the serum and cerebrospinal fluid (CSF) target NMDA receptors. Glial fibrillary acidic protein (GFAP) astrocytopathy is an autoimmune disease affecting the central nervous system (CNS). Meningoencephalitis can affect any anatomical region rostrocaudally, from the optic nerve to the spinal cord. The clinical implications of NMDAR antibodies overlapping with other antibodies against glial or neuronal cell surface proteins have not been investigated.

Case presentation

A 35-year-old male presented with headaches along with amnesia, slurred and awkward speech, psychiatric symptoms, cognitive decline, and insomnia. His medical history revealed ankylosing spondylitis for six months. Ancillary findings included CSF pleocytosis and elevated protein levels. T2-weighted fluid attenuation inversion recovery was used to image high-intensity lesions of the bilateral paraventricular, radiate corona, semioval centre, and right subcortical regions. The CSF was positive for NMDAR and GFAP antibodies through transfected cell-based assays. A diagnosis of anti-GFAP encephalitis was made, although the prominent clinical features were of anti-NMDAR encephalitis.

Conclusions

Herein, we describe a case of anti-NMDAR encephalitis with overlapping symptoms of GFAP antibody positivity. Patients with unusual symptoms of anti-NMDAR encephalitis should also be tested for anti-GFAP antibodies. However, because this was a single case study, caution should be exercised when interpreting the observations. Since the patient was diagnosed with autoimmune encephalitis, intravenous methylprednisolone was administered, which yielded a positive outcome.
Prognostic and clinical significance of HER-2 low expression in early-stage gastric cancer
Authors: Yang Tao , Xu Rui , You Junhao , Li Fang , Yan Bing , Cheng Jia-nan
Published: November 2022

Introduction

Gastric cancer is the most fifth common tumor worldwide. Human epidermal growth factor receptor 2 (HER2) overexpression is associated with poor prognosis and clinical characteristics in gastric cancer. Nevertheless, the biology of HER2-low expression has not reported in gastric cancer.

Materials and methods

A total of 157 patients with early-stage gastric cancer were retrospectively analyzed. The associations between HER-2 low expression and clinical characteristics were analyzed by Chi-square test. And the prognostic value of HER-2 low expression and clinical characteristics in disease-free survival (DFS) and overall survival (OS) were analyzed by univariate and multivariate Cox regression analysis.

Results

Of 157 patients with early-stage gastric cancer, 31.8% had HER2-low tumors and 50.3% had HER2-negative tumors. HER2-low expression was associated with age, histological differentiation, tumor location and Ki-67 index. However, HER2-low expression was not associated with DFS or OS in early-stage gastric cancer.

Conclusion

HER2-low expression might result in distinct biology, but it was not an independent prognostic factor of DFS or OS in early-stage gastric cancer.
The smoke-free home study: study protocol for a cluster randomized controlled trial of a smoke-free home intervention in permanent supportive housing
Authors: Odes Rachel , Alway Jessica , Kushel Margot , Max Wendy , Vijayaraghavan Maya
Published: November 2022

Background

Formerly chronically homeless adults who live in permanent supportive housing (PSH) have high prevalence of smoking. It is uncommon to find smoke-free policies in PSH because of the concern that such policies contradict PSH’s harm reduction framework and could increase homelessness should residents lose their housing because of the policy. However, in the absence of such policies, non-smoking PSH residents face the harmful effects of secondhand smoke exposure while residents who smoke see increased risks from high rates of smoking throughout their residence. Our pilot work highlighted the feasibility and acceptability of an intervention designed to promote voluntary adoption of a smoke-free home. Here we report a protocol for a cluster randomized controlled trial of the smoke-free home intervention for formerly chronically homeless residents in PSH.

Methods

The smoke-free home intervention provides face-to-face counseling and instruction to PSH residents on how to adopt a smoke-free home and offers training for PSH staff on how to refer residents to tobacco cessation services. We will randomize 20 PSH sites in the San Francisco Bay Area to either the intervention or wait-list control arms. We will enroll 400 PSH residents who smoke cigarettes in their housing unit and 120 PSH staff who work at the sites. At baseline, three- and six-months follow-up, we will ask residents to report their tobacco use and cessation behaviors and adoption of smoke-free homes. We will ask staff to answer questions on their knowledge, attitudes, practices, and barriers related to supporting residents’ smoking cessation. The primary outcome for PSH residents is adoption of smoke-free homes for 90 days or more at six-months follow-up, and the secondary outcome is point prevalence tobacco abstinence. The primary outcome for PSH staff is change in Smoking Knowledge Attitudes Practices survey score.

Discussion

Voluntary adoption of smoke-free homes is a promising approach for reducing exposure to secondhand smoke and reducing tobacco use among a population facing high rates of tobacco-related disease, and is aligned with PSH’s harm reduction framework. Findings from this study have the potential to inform adoption of tobacco control policies among vulnerable populations most at risk for smoking-related harms.

Trial registration

This study was registered with the U.S. National Institute of Health Clinical Trials register on April 22, 2021: NCT04855357.

Published: November 2022

Background

Although a safe and effective vaccine is available, measles remains an important cause of mortality and morbidity among young children in Sub-Saharan Africa (SSA). The WHO and UNICEF recommended measles-containing vaccine dose 2 (MCV2) in addition to measles-containing vaccine dose 1 (MCV1) through routine services strategies. Many factors could contribute to the routine dose of MCV2 coverage remaining far below targets in many countries of this region. This study aimed to assess the prevalence of MCV2 utilization among children aged 24–35 months and analyze factors associated with it by using recent nationally representative surveys of SSA countries.

Methods

Secondary data analysis was done based on recent Demographic and Health Surveys (DHS) data from eight Sub-Saharan African countries. In this region, only eight countries have a record of routine doses of measles-containing vaccine dose 2 in their DHS dataset. The multilevel binary logistic regression model was fitted to identify significantly associated factors. Variables were extracted from each of the eight country’s KR files. Adjusted Odds Ratios (AOR) with a 95% Confidence Interval (CI) and p-value ≤ 0.05 in the multivariable model were used to declare significant factors associated with measles-containing vaccine dose 2 utilization.

Result

The pooled prevalence of MCV2 utilization in SSA was 44.77% (95% CI: 27.10–62.43%). In the multilevel analysis, mothers aged 25–34 years [AOR = 1.15,95% CI (1.05–1.26), mothers aged 35 years and above [AOR = 1.26, 95% CI (1.14–1.41)], maternal secondary education and above [AOR = 1.27, 95% CI (1.13–1.43)], not big problem to access health facilities [AOR = 1.21, 95% CI (1.12–1.31)], four and above ANC visit [AOR = 2.75, 95% CI (2.35–3.24)], PNC visit [AOR = 1.13, 95% CI (1.04–1.23)], health facility delivery [AOR = 2.24, 95% CI (2.04–2.46)], were positively associated with MCV2 utilization. In contrast, multiple twin [AOR = 0.70, 95% CI (0.53–0.95)], rural residence [AOR = 0.69, 95% CI (0.57–0.82)] and high community poverty [AOR = 0.66, 95% CI (0.54–0.80)] were found to be negatively associated with MCV2 utilization.

Conclusions and recommendations

Measles-containing vaccine doses 2 utilization in Sub-Saharan Africa was relatively low. Individual-level factors and community-level factors were significantly associated with low measles-containing vaccine dose 2 utilization. The MCV2 utilization could be improved through public health intervention by targeting rural residents, children of uneducated mothers, economically poor women, and other significant factors this study revealed.
Development of the Home-Based Fall Prevention Knowledge (HFPK) questionnaire to assess home-based fall prevention knowledge levels among older adults in China
Authors: Yang Yuting , Ye Qiong , Yao Miao , Yang Yongwei , Lin Ting
Published: November 2022

Background

Falls are one of the main reasons for mortality and morbidity in older adults. However, despite adoption of prevention strategies, the number of falls in older adults has not declined. This study aimed to develop a questionnaire to assess fall prevention knowledge and explore associated factors among Chinese community-dwelling older adults.

Methods

The Home-Based Fall Prevention Knowledge (HFPK) questionnaire was developed by Delphi expert consultation. We tested the internal consistency, reliability, and content validity of the HFPK. A total of 374 community-dwelling older adults participated in this study. The HFPK was used to assess their fall prevention knowledge.

Results

After being evaluated by 15 experts, the item content validity index ranged from 0.867 to 1, and the scale content validity index was 0.985, which met the criterion for content validity. Cronbach’s α coefficient was 0.933, which satisfied the reliability criterion. Stepwise linear regression analysis showed that fall prevention knowledge was significantly associated with having higher education, being female, having a higher monthly income, people who were public officials before retirement, and having fewer children (p < 0.05).

Conclusion

Fall prevention knowledge should be improved among older males and those with lower education, lower monthly income, people who were not public officials before retirement, and more children.

Authors: Li MingYang , Lyu ChengYu , Fang Yuan , Shao ZhenShuai , Liu Kun , Liu Ning
Published: November 2022

Background

Postoperative fever (POF) is a common problem after total joint arthroplasty (TJA). The goal of this research is to analyze the characteristics and risk factors of fever following TJA.

Methods

We retrospectively investigated 2482 patients who had primary total knee arthroplasty (TKA) or total hip arthroplasty (THA) surgery at our institution between January 2020 and December 2020. Those patients were divided into TKA group and THA group. The patients' axillary temperatures were measured. POF was defined as a body temperature greater than 38 °C. Then patients in the TKA and THA groups were respectively divided into afebrile group and febrile group based on their body temperatures. Temperature changing characteristics of the patients in the febrile group were analyzed and recorded. According to the number of patients in the febrile group, we randomly selected a corresponding number of patients from the afebrile group at a ratio of 1:2 to establish a control group. Gender, hypertension, diabetes, anesthesia, surgical time, and some laboratory data were analyzed between the febrile group and the afebrile group.

Results

Three percent of TKA patients (N = 45) had febrile, and in the febrile group of TKA group, 38% (N = 17) had fever and maximum body temperature on postoperative day 2(POD2). Six percent of THA patients (N = 46) had fever, and in the febrile group of THA group, 65% (N = 30) of the patients had fever and maximum body temperature on POD1. In TKA group, compared with afebrile group, febrile group has higher C-reactive protein (mg/L) (CRP) after surgery. In THA group, compared with the afebrile group, the patients in the febrile group had larger fall in hemoglobin (g/L), and higher C-reactive protein (mg/L) (CRP) after surgery, so there were statistically significant differences between the two groups (P < 0.05).

Conclusion

The POF rate of TKA is 3%, and the first fever and maximum body temperature most commonly appear on the POD2. THA has a 6% POF rate, and the first fever and the maximum body temperature most commonly appear on the POD1. In both groups, high C-reactive protein is a risk factor for postoperative fever. In addition, the fall in hemoglobin is also related to postoperative fever in the THA group.

Authors: Yang Qifan , Liu Jing , Liu Chengyan , Zhou Pengcheng , Zhu Dong
Published: November 2022

Background

This study performed a randomized trial data meta-analysis to assess The Modified Brostrom-Gould (MBG) for proven chronic lateral ankle instability (CLAI).

Methods

All published randomized clinical trials comparing MBG and other operations were found by searching the Cochrane Library, EMBASE, and PubMed databases. The Review Manager 5.4 software was used to compare the two groups regarding postoperative functional score, ankle stability, and complications. Risk Ratio (RR) and Mean Differences (MD) were used in meta-analyses.

Results

8 experiments are suitable for it, 426 patients were enrolled, and 222 patients underwent other operations surgery. Among the six outcome indicators, in terms of FAOS scores, the other operations group has an advantage, 6.53 points higher than MBG; others show no significant differences.

Conclusions

Based on this meta-analysis, the authors believe that other surgical groups can achieve better outcomes than MBG in some aspects of CLAI treatment.
Hypoparathyroidism and late-onset hypogonadism in an adult male with familial 22q11.2 deletion syndrome: a case report with 3-year follow-up and review of the literature
Authors: Chen Xuelian , Yang Lichuan , Li Jianwei , Tan Huiwen
Published: November 2022

Background

22q11.2 deletion syndrome (DiGeorge syndrome) is associated with multiple organ dysfunctions such as cardiac defects, immunodeficiency, and hypoplasia of parathyroid glands. Moreover, the phenotype of 22q11.2 DS has clinical variability and heterogeneity.

Case presentation

In this report, we present the case of a 35-year-old patient with a past medical history that included recurrent infections, mild learning difficulties in childhood, pediatric obesity, and cataract. He was admitted to the endocrinology department for the management of hypogonadism and hypocalcemia. During the 3-year follow-up, the patient gradually developed primary hypoparathyroidism, hypogonadism, chronic renal failure, and heart failure, and his medical condition deteriorated. Meanwhile, in order to improve clinicians’ awareness of the endocrine manifestations of adult 22q11.2 DS and reduce missed diagnoses, we reviewed 28 case reports of adult 22q11.2 DS to analyze the clinical characteristics.

Discussion

Here, we report the case of a young man diagnosed with 22q11.2 DS presented a rare combination of multiple endocrine disorders. This is the first time that a patient with 22q11.2DS had late-onset hypogonadism caused by primary testicular failure combined with decreased pituitary gonadotropin reserve in a patient with 22q11.2DS.
Left adrenal aldosteronism coexisting with left paraaortic paraganglioma presenting as bilateral adrenal and left paraaortic tumors– comprehensive adrenal evaluation aiding perfect management: a case report
Authors: Hsu Yu-Chen , Lee Cheng-Han , Chen Chen-Yu , Hung Chung-Jye
Published: November 2022

Background

Coexistence of a catecholamine-secreting tumor and an adrenal cortical tumor is quite rare which makes both diagnosis and management challenging. The purpose of this article is to describe the presence of this condition, share a stepwise approach for preoperative evaluation, and review the related literature.

Case presentation

A 44-year-old male patient had a history of hypertension and aggravating hypokalemia for years. Abdominal computed tomography incidentally found concomitant bilateral adrenal and left para-aortic tumors. Comprehensive adrenal hormone tests revealed a high aldosterone renin ratio and mildly elevated 24-h urine vanillylmandelic acid and norepinephrine levels. Subsequently, a metaiodobenzylguanidine scan showed uptake over the left para-aortic tumor, and NP-59 adrenal scintigraphy showed uptake over the left adrenal tumor. Further confirmatory tests, including captopril suppression, irbesartan suppression, and saline infusion, all confirmed the diagnosis of hyperaldosteronism. Adrenal venous sampling following 2 months of preparation with an alpha blocker demonstrated a left aldosterone-producing adrenal adenoma. Combining hormonal analysis, imaging studies, and adrenal venous sampling, the patient was diagnosed with left adrenal aldosteronoma, right adrenal nonfunctional tumor, and left para-aortic paraganglioma (PGL). Accordingly, laparoscopic left adrenalectomy and left PGL excision were performed smoothly under alpha blocker maintenance. The pathology report confirmed left adrenal cortical adenoma and left para-aortic PGL. Postoperatively, the blood pressure, biochemical tests, and adrenal hormone assays returned to normal, and related symptoms disappeared and were relatively stable during the follow-up period of two years.

Conclusions

This is the first case of left para-aortic PGL coexisting with an ipsilateral aldosterone-producing adenoma presenting as a left para-aortic tumor associated with bilateral adrenal tumors. Awareness of the rarity of this coexistence can avoid unexpected disasters during the process of evaluation and management.

Authors: Angel Marina , Petrosyan Yelena , Doyle Mary-Anne , Cooper Curtis
Published: November 2022

Background

The interplay between HCV, DM, and DAA therapy is poorly understood. We compared HCV infection characteristics, treatment uptake, and treatment outcomes in patients with and without DM. 

Methods

A retrospective cohort study was conducted using data from The Ottawa Hospital Viral Hepatitis Program. Statistical comparisons between diabetes and non-diabetes were made using χ2 and t-tests. Logistic regression analyses were performed to assess predictors of DM and SVR.

Results

One thousand five hundred eighty-eight HCV patients were included in this analysis; 9.6% had DM. Patients with DM were older and more likely to have cirrhosis. HCC and chronic renal disease were more prevalent in the DM group. Treatment uptake and SVR were comparable between groups. Regression analysis revealed that age and employment were associated with achieving SVR. Post-SVR HCC was higher in DM group.

Conclusion

The high prevalence of DM in our HCV cohort supports screening. Further assessment is required to determine if targeted, early DAA treatment reduces DM onset, progression to cirrhosis and HCC risk. Further studies are needed to determine if optimization of glycemic control in this population can lead to improved liver outcomes.

Published: November 2022

Context

The COVID-19 pandemic created a worldwide public health emergency, in which hospitals created new COVID departments and doctors from different disciplines had to work together. In the Netherlands, a large proportion of doctors in these departments were residents. With knowledge of the disease developing only gradually, the influx of COVID-19 patients called for adaptability, innovative work behavior, and intraprofessional collaboration (intraPC) between residents and between residents and medical specialists.

Research goal

This study investigates how the delivery of COVID-19 care in hospital settings altered the way residents develop their sense of adaptability and intraPC during their training.

Methods

Sixteen semi-structured interviews were conducted with residents and medical specialists from various disciplines who worked at a COVID department or Intensive Care Unit (ICU) during the COVID pandemic in the Netherlands, focusing on adaptability and intraPC learning. Transcripts were analyzed using (thematic) template analysis.

Results

Four themes that influenced learning during COVID care were identified: collective uncertainty, social cohesion and a sense of safety, the need for adaptive performance and intraPC learning. During the first wave, collective uncertainty about the unknown disease and the continuation of the crisis urged residents to adapt in order to take care of patients with a disease that was as yet unknown. The combination of collective uncertainty, social cohesion and a sense of safety, and the presence of different disciplines in one department promoted residents’ intraPC learning. However, intraPC learning was not always the matter of course due to the scope of the crisis and the huge numbers of new patients.

Conclusion

Collective uncertainty affected the residents’ adaptability. The combination of collective uncertainty, social cohesion, and the presence of different disciplines in one department promoted the residents’ intraPC learning. An important facilitating factor for both adaptability and intraPC learning is a high level of social cohesion and safety. The physical and psychological proximity of supervisors is an important factor contributing to a safe learning environment. This study provides implications for practice for learning during postgraduate training in non-crisis settings.
Clinical decision support system for quality of life among the elderly: an approach using artificial neural network
Authors: Ahmadi Maryam , Nopour Raoof
Published: November 2022

Background

Due to advancements in medicine and the elderly population’s growth with various disabilities, attention to QoL among this age group is crucial. Early prediction of the QoL among the elderly by multiple care providers leads to decreased physical and mental disorders and increased social and environmental participation among them by considering all factors affecting it. So far, it is not designed the prediction system for QoL in this regard. Therefore, this study aimed to develop the CDSS based on ANN as an ML technique by considering the physical, psychiatric, and social factors.

Methods

In this developmental and applied study, we investigated the 980 cases associated with pleasant and unpleasant elderlies QoL cases. We used the BLR and simple correlation coefficient methods to attain the essential factors affecting the QoL among the elderly. Then three BP configurations, including CF-BP, FF-BP, and E-BP, were compared to get the best model for predicting the QoL.

Results

Based on the BLR, the 13 factors were considered the best factors affecting the elderly’s QoL atP < 0.05. Comparing all ANN configurations showed that the CF-BP with the 13-16-1 structure with sensitivity = 0.95, specificity  =  0.97, accuracy = 0.96, F-Score = 0.96, PPV = 0.95, and NPV = 0.97 gained the best performance for QoL among the elderly.

Conclusion

The results of this study showed that the designed CDSS based on the CFBP could be considered an efficient tool for increasing the QoL among the elderly.
Implementing a complex hospital innovation: conceptual underpinnings, program design and implementation of a complex innovation in an international multi-site hospital trial
Authors: Dryden-Palmer Karen , Berta Whitney B. , Parshuram Christopher S.
Published: November 2022

Background

Designing implementation programs that effectively integrate complex healthcare innovations into complex settings is a fundamental aspect of knowledge translation. We describe the development of a conceptually grounded implementation program for a complex healthcare innovation and its subsequent application in pediatric hospital settings.

Methods

We conducted multiple case observations of the application of the Phased Reciprocal Implementation Synergy Model (PRISM) framework in the design and operationalization of an implementation program for a complex hospital wide innovation in pediatric hospital settings.

Results

PRISM informed the design and delivery of 10 international hospital wide implementations of the complex innovation, BedsidePEWS. Implementation and innovation specific goals, overarching implementation program design principles, and a phased-based, customizable, and context responsive implementation program including innovation specific tools and evaluation plans emerged from the experience.

Conclusion

Theoretically grounded implementation approaches customized for organizational contexts are feasible for the adoption and integration of this complex hospital-wide innovation. Attention to the fitting of the innovation to local practices, setting, organizational culture and end-user preferences can be achieved while maintaining the integrity of the innovation.
High-cost users: drivers of inpatient healthcare expenditure concentration in urban China
Authors: Fan Qiuyan , Wang Jian , Nicholas Stephen , Maitland Elizabeth
Published: November 2022

Background

Total healthcare expenditures are concentrated among a small number of patients. To date, studies on the concentration of health care expenditures in developing countries are limited, mainly focusing on concentration measures and the demographic, clinical and socioeconomic characteristics of high-cost users (HCU). The drivers of the skewed overall distribution of health care expenditures are opaque. Using inpatient administrative claims data, this study provides new evidence on the concentration of healthcare expenditures in China; the demographic and clinical characteristics of high-cost users; and the drivers of the overall distribution of healthcare expenditures.

Methods

Utilizing administrative claims data for hospitalization in a prefecture-level city in China, we investigated the concentration of healthcare expenditure. We used recentered influence function (RIF) regression to examine the drivers of healthcare expenditure concentration, decomposing and estimating the effects of demographic and disease characteristics on the overall distribution of health care expenditures.

Results

Using a sample of 87,841 adults, we found extreme skewness in the distribution of inpatient medical expenditures in China, with approximately 49% of annual medical expenditures generated by the top 10% of inpatient groups. HCUs tend to be elderly and male, with high-frequency hospitalizations and long lengths of stay. In addition, healthcare expenditure concentration was related to diseases of the circulatory system, malignant neoplasms, diseases of the musculoskeletal system and connective tissue, diseases of the digestive system, injury and poisoning, and diseases of the respiratory system. Malignant and major diseases reinforced the concentration of healthcare spending, and a 10% increase in the prevalence of malignancy would result in a predicted Gini coefficient increase of 7.2%, heart disease of 0.92% and cerebrovascular disease of 1.5%. The above significant positive effects were not observed for hypertension and diabetes mellitus.

Conclusions

Our study provides new insights into the concentration of inpatient medical expenditures in China, including the precise picture of HCU expenditure concentration, the drivers of HCU expenditure concentration and the magnitude of their impact. With the aging of China's population and the profound shift in the disease spectrum, policymakers need to strengthen the early detection and intervention management of specific chronic diseases and high-risk populations, especially the early diagnosis and treatment of key cancers.
Induction of pyroptotic cell death as a potential tool for cancer treatment
Authors: Faria Sara Socorro , Fernando Anuruddika Jayawanthi , de Lima Vladmir Cláudio Cordeiro , Rossi Adriano Giorgio , de Carvalho Juliana Maria Andrade , Magalhães Kelly Grace
Published: November 2022

Cancer is a complex pathological disease and the existing strategies for introducing chemotherapeutic agents have restricted potential due to a lack of cancer cell targeting specificity, cytotoxicity, bioavailability, and induction of multi-drug resistance. As a prospective strategy in tackling cancer, regulating the inflammatory pyroptosis cell death pathway has been shown to successfully inhibit the proliferation and metastasis of various cancer cell types. Activation of inflammasomes such as the NLRP3 results in pyroptosis through cleavage of gasdermins, which forms pores in the cell membranes, inducing membrane breakage, cell rupture, and death. Furthermore, pyroptotic cells release pro-inflammatory cytokines such as IL-1β and IL-18 along with various DAMPs that prime an auxiliary anti-tumor immune response. Thus, regulation of pyroptosis in cancer cells is a way to enhance their immunogenicity. However, immune escape involving myeloid-derived suppressor cells has limited the efficacy of most pyroptosis-based immunotherapy strategies. In this review, we comprehensively summarize the cellular and molecular mechanisms involved in the inflammasome-mediated pyroptosis pathways in cancer cells, exploring how it could modulate the tumor microenvironment and be beneficial in anti-cancer treatments. We discuss various existing therapeutic strategies against cancer, including immunotherapy, oncolytic virus therapy, and nanoparticle-based therapies that could be guided to trigger and regulate pyroptosis cell death in cancer cells, and reduce tumor growth and spread. These pyroptosis-based cancer therapies may open up fresh avenues for targeted cancer therapy approaches in the future and their translation into the clinic.

Background

COVID-19 infections could be complicated by acute respiratory distress syndrome (ARDS), increasing mortality risk. We sought to assess the methylome of peripheral blood mononuclear cells in COVID-19 with ARDS.

Methods

We recruited 100 COVID-19 patients with ARDS under mechanical ventilation and 33 non-COVID-19 controls between April and July 2020. COVID-19 patients were followed at four time points for 60 days. DNA methylation and immune cell populations were measured at each time point. A multivariate cox proportional risk regression analysis was conducted to identify predictive signatures according to survival.

Results

The comparison of COVID-19 to controls at inclusion revealed the presence of a 14.4% difference in promoter-associated CpGs in genes that control immune-related pathways such as interferon-gamma and interferon-alpha responses. On day 60, 24% of patients died. The inter-comparison of baseline DNA methylation to the last recorded time point in both COVID-19 groups or the intra-comparison between inclusion and the end of follow-up in every group showed that most changes occurred as the disease progressed, mainly in the AIM gene, which is associated with an intensified immune response in those who recovered. The multivariate Cox proportional risk regression analysis showed that higher methylation of the “Apoptotic execution Pathway” genes (ROC1, ZNF789, and H1F0) at inclusion increases mortality risk by over twofold.

Conclusion

We observed an epigenetic signature of immune-related genes in COVID-19 patients with ARDS. Further, Hypermethylation of the apoptotic execution pathway genes predicts the outcome.

Published: November 2022

Background

Pulmonary fibrosis is a chronic progressive fibrotic interstitial lung disease characterized by excessive extracellular matrix (ECM) deposition caused by activated fibroblasts. Increasing evidence shows that matrix stiffness is essential in promoting fibroblast activation and profibrotic changes. Here, we investigated the expression and function of matrix stiffness-regulated ZNF416 in pulmonary fibrotic lung fibroblasts.

Methods

1 kappa (soft), 60 kappa (stiff) gel-coated coverslips, or transforming growth factor-beta 1 (TGF-β1)-cultured lung fibroblasts and the gain- or loss- of the ZNF416 function assays were performed in vitro. We also established two experimental pulmonary fibrosis mouse models by a single intratracheal instillation with 50 mg/kg silica or 6 mg/kg bleomycin (BLM). ZNF416 siRNA-loaded liposomes and TGF-β1 receptor inhibitor SB431542 were administrated in vivo.

Results

Our study identified that ZNF416 could regulate fibroblast differentiation, proliferation, and contraction by promoting the nuclear accumulation of p-Smad2/3. Besides, ZNF416 siRNA-loaded liposome delivery by tail-vein could passively target the fibrotic area in the lung, and co-administration of ZNF416 siRNA-loaded liposomes and SB431542 significantly protects mice against silica or BLM-induced lung injury and fibrosis.

Conclusion

In this study, our results indicate that mechanosensitive ZNF416 is a potential molecular target for the treatment of pulmonary fibrosis. Strategies aimed at silencing ZNF416 could be a promising approach to fight against pulmonary fibrosis.
‘It is a hard decision’: a qualitative study of perinatal intimate partner violence disclosure
Authors: Amel Barez Malikeh , Mirzaii Najmabadi Khadijeh , Latifnejad Roudsari Robab , Mousavi Bazaz Mojtaba , Babazadeh Raheleh
Published: November 2022

Background

Perinatal intimate partner violence is a hidden under reported and difficult to identify problem which has negative effects on mother and child. The present study aimed to explore barriers and facilitators of perinatal intimate partner violence disclosure.

Methods

This qualitative study was carried out from October 2019 to January 2021 in Mashhad, Iran. Participants included 23 abused women (11 pregnant and 12 after birth) which were selected via purposive sampling. Semi-structured in-depth interviews and focus group discussion were conducted until the data saturation was achieved. The data analysis was performed based on conventional content analysis adopted by Graneheim & Lundman.

Results

The main themes “barriers to disclosure” and “facilitators of disclosure” were emerged as the result of data analysis. Barriers to disclosure included negative disclosure consequences and protection of family privacy. Facilitators of disclosure included maternal self-efficacy, threats to security, and formal and informal supportive networks.

Conclusions

Most abused women did not disclose violence despite routine screening for perinatal intimate partner violence in antenatal care. Recognizing the barriers to and facilitators of violence disclosure play an important role in eliminating barriers, strengthening facilitators, providing effective supportive services for abused women, and reducing perinatal violence. Focus on the barriers to and the facilitators of disclosure will be useful to policymakers, health program planners, and health care providers to identify and manage intimate partner violence, appropriately.
Can you be a manual therapist without using your hands?
Authors: Saragiotto Bruno T. , Sandal Louise F. , Hartvigsen Jan
Published: November 2022

Background

To align with current best practices, manual therapists have refined their treatment options to include exercise and pain education for people with chronic musculoskeletal pain. In this commentary, we suggest that manual therapists should also add telehealth to their toolbox. Thus, we aim to discuss the use of telehealth by manual therapists caring for patients with musculoskeletal disorders.

Main body

Telehealth can be delivered to the patient in different modes, such as real-time clinical contact or asynchronously. Platforms vary from websites and smartphone apps to virtual reality systems. Telehealth may be an effective approach, especially for improving pain and function in people with musculoskeletal pain, and it has the potential to reduce the individual and socioeconomic burden of musculoskeletal conditions. However, the certainty of evidence reported in systematic reviews is often low. Factors such as convenience, flexibility, undivided attention from the clinician, user-friendly platforms, goal setting, and use of evidence-based information are all enablers for telehealth use and improving patients’ knowledge, self-efficacy, and self-management. Barriers to widening the use of telehealth in musculoskeletal care include the reliability of technology, data privacy issues, difficult to build therapeutic alliance, one-size-fits-all approaches, digital health literacy, and payment models.

Conclusion

We suggest that practitioners of manual medicine make telehealth part of their clinical toolbox where it makes sense and where there is evidence that it is beneficial for people who seek their care.
A novel missense mutation in GREB1L identified in a three-generation family with renal hypodysplasia/aplasia-3
Authors: Wu Sixian , Wang Xiang , Dai Siyu , Zhang Guohui , Zhou Jiaojiao , Shen Ying
Published: November 2022

Background

Renal hypodysplasia/aplasia-3 (RHDA3), as the most severe end of the spectrum of congenital anomalies of the kidney and urinary tract, is mainly caused by mutations in GREB1L. However, the mutations in GREB1L identified to date only explain a limited proportion of RHDA3 cases, and the mechanism of GREB1L mutations causing RHDA3 is unclear.

Results

According to whole-exome sequencing, a three-generation family suffering from RHDA3 was investigated with a novel missense mutation in GREB1L, c.4507C>T. All three-generation patients suffered from unilateral absent kidney. This missense mutation resulted in sharp downregulation of mRNA and protein expression, which might lead to RHDA3. Mechanistically, through RNA-sequencing, it was found that the mRNA levels of PAX2 and PTH1R, which are key molecules involved in the development of the kidney, were significantly downregulated by knocking out GREB1L in vitro.

Conclusions

This novel missense mutation in GREB1L can be helpful in the genetic diagnosis of RHDA3, and the discovery of the potential mechanism that GREB1L mutations involved in RHDA3 pathogenesis can promote the adoption of optimal treatment measures and the development of personalized medicine directly targeting these effects.
