Background

Breastfeeding protects against a range of conditions in the infant, including sudden infant death syndrome (SIDS), diarrhoea, respiratory infections and middle ear infections [1, 2]. The World Health Organization (WHO) recommends exclusive breastfeeding until six months of age, with continued breastfeeding recommended for at least two years and other complementary nutritious foods [3]. The 2017-18 National Health Survey (NHS) and 2018-19 National Aboriginal and Torres Strait Islander Health Survey (NATSIHS) reported that the proportion of breastfeeding in Aboriginal and Torres Strait Islander infants (0–2 years) were less than half that of non-Indigenous infants (21.2% vs. 45%, respectively)[4]. There is a lack of research on interventions supporting Aboriginal women to breastfeed, identifying an evaluation gap related to peer support interventions to encourage exclusive breastfeeding in Aboriginal women.

Methods

We will evaluate the effect of scheduled breastfeeding peer support for and by Aboriginal women, on breastfeeding initiation and the prevalence of exclusive breastfeeding. This MRFF (Medical Research Future Fund) funded project is designed as a single-blinded cluster randomised controlled trial recruiting six sites across New South Wales, Australia, with three sites being randomised to employ a peer support worker or undertaking standard care. Forty pregnant women will be recruited each year from each of the six sites and will be surveyed during pregnancy, at six weeks, four and six months postnatally with a single text message at 12 months to ascertain breastfeeding rates. In-depth interviews via an Indigenous style of conversation and storytelling called ‘Yarning’ will be completed at pre- and post-intervention with five randomly recruited community members and five health professionals at each site” [5]. Yarns will be audio recorded, transcribed, coded and thematic analysis undertaken. Health economic analysis will be completed to assess the health system incremental cost and effects of the breastfeeding intervention relative to usual care.

Discussion

Evidence will be given on the effectiveness of Aboriginal peer support workers to promote the initiation and continuation of breastfeeding of Aboriginal babies. The findings of this study will provide evidence of effectiveness and cost-effectiveness of including peer support workers in postnatal care to promote breastfeeding practices.

Psychometric properties of the Burnout Assessment Tool across four countries
Authors: Redelinghuys Kleinjan , Morgan Brandon
Published: May 2023

Background

The Burnout Assessment Tool (BAT) is a new burnout measure developed to replace the Maslach Burnout Inventory (MBI). Studies have supported the psychometric properties and cross-cultural measurement invariance of the BAT. However, some unresolved questions remain. These questions are the appropriate level of score interpretation, convergent validity with the MBI, and measurement invariance using sample groups from countries outside of Europe.

Methods

We used a cross-sectional survey approach to obtain 794 participants from Australia (n = 200), the Netherlands (n = 199), South Africa (n = 197), and the United States (n = 198). In brief, we used bifactor modelling to investigate the appropriate score interpretation and convergent validity with the MBI. Hereafter, we used the Rasch model and ordinal logistic regression to investigate differential item functioning.

Results

The bifactor model showed a large general factor and four small group factors, which suggests calculating and interpreting a general burnout score. This model further shows that the BAT and MBI measure the same burnout construct but that the BAT is a more comprehensive burnout measure. Most items fit the Rasch model, and few showed non-negligible differential item functioning.

Conclusions

Our results support the psychometric properties and cross-cultural measurement invariance of the BAT in Australia, the Netherlands, South Africa, and the United States. Furthermore, we provide some clarity on the three previously mentioned unresolved questions.
Barriers to the participation of men in reproductive health care: a systematic review and meta-synthesis
Authors: Roudsari Robab Latifnejad , sharifi Farangis , Goudarzi Fatemeh
Published: May 2023

Background

Despite emphasizing the importance and benefits of men's active engagement in reproductive health programs, their engagement in reproductive health care is low. Researchers have identified different barriers to men's avoidance of participation in various aspects of reproductive health in different parts of the world. This study provided an in-depth review of the hindrances to men’s non-participation in reproductive health.

Methods

This meta-synthesis was conducted using keyword searches in databases including PubMed, Scopus, Web of Science, Cochrane, and ProQuest until January 2023. Qualitative English-language studies that investigated barriers to men's participation in reproductive health were included in the study. The critical appraisal skills program (CASP) checklist was used to assess the articles' quality. Data synthesis and thematic analysis were done using the standard method.

Result

This synthesis led to the emergence of four main themes such as failure to access all inclusive and integrated quality services, economic issues, couples' personal preferences and attitudes, and sociocultural considerations to seek reproductive healthcare services.

Conclusion

Healthcare system programs and policies, economic and sociocultural issues, and men’s attitudes, knowledge, and preferences, influence men's participation in reproductive healthcare. Reproductive health initiatives should focus on eliminating challenges to men's supportive activities to increase practical men's involvement in reproductive healthcare.
Plate fixation using parallelogram prism iliac bone grafts for clavicle oblique nonunion with shortening deformity: a case report
Authors: Furuhata Ryogo , Yokoyama Yuya , Tanji Atsushi , Fujita Shota
Published: May 2023

Background

Plate fixation using a tricortical iliac bone graft can provide a high ratio of bone union and restore clavicle length in cases of atrophic nonunion. However, the surgical treatment of clavicle oblique nonunions with marked shortening deformity remains challenging and unresolved. Here, we describe a case of clavicle oblique nonunion with shortening that was treated using plate fixation with parallelogram prism iliac bone grafts.

Case presentation

A 46-year-old man presented to our hospital with severe medial scapular pain. He had been diagnosed with a right clavicle mid-shaft fracture in a motorcycle accident 9 months earlier. He underwent conservative treatment, but radiographs and computed tomography showed clavicle oblique nonunion with marked shortening. Physical examination revealed no pain at the nonunion site; however, tenderness was noted on the medial side of the right scapula and protrusion of the inferior scapular angle was prominent. His symptoms interfered with daily life and required surgery. After release of the nonunion, we harvested the parallelogram prism bone grafts from the iliac crest. We inserted these bone grafts into the fracture ends and fixed them with lag screws, after which we performed plate fixation. Immediately after surgery, right medial scapular pain and scapula winging subsided. Bone union was achieved, and the length of the clavicle was restored at 9 months postoperatively.

Conclusions

This case report provides new information on the surgical treatment of clavicle oblique nonunion with shortening deformity. The presence of medial scapular pain and winging scapula can be clinically problematic in cases of clavicle nonunion with marked shortening. Our case revealed that reliable bone union and clavicle length recovery can be achieved with plate fixation and iliac bone grafts.

Authors: Su Weijie , He Kejun , Yang Yibing , Xu Jiakun , Li Xixi , Tang Hongxing , Yang Jia , Yang Lixuan
Published: May 2023

Background

The optimal therapeutic approach for cystic prolactinomas remains unclear. This study aimed to evaluate the remission rates of prolactinoma patients after surgical treatment and the risk factors affecting postoperative remission in cystic prolactinoma patients.

Methods

The clinical data were retrospectively compiled from 141 patients with prolactinomas (including 41 cases of cystic prolactinomas, 21 cases of solid microprolactinomas and 79 cases of solid macroprolactinomas) who underwent transsphenoidal surgery (TSS) between April 2013 and October 2021 at the First Affiliated Hospital of Sun Yat-sen University.

Results

Early postoperative remission was achieved in 65.83% (n = 27/41) of cystic prolactinomas, 80.95% (n = 17/21) of solid microprolactinomas and 40.51% (n = 32/79) of solid macroprolactinomas. The mean length of follow up in all patients was 43.95 ± 2.33 months (range: 6-105 months). The follow-up remission rates were 58.54%, 71.43% and 44.30% in cystic, solid micro- and solid macroprolactinomas, respectively. For cystic prolactinomas, the early postoperative remission rates in the patients with preoperative dopamine agonists (DA) treatment were significantly higher than those without preoperative DA treatment (p = 0.033), but the difference in the follow-up remission rates between these two groups was not significant (p = 0.209). Multivariate stepwise logistic regression analysis indicated that tumor size and preoperative prolactin (PRL) levels < 200 ng/ml were independent predictors for early postoperative remission in cystic prolactinomas.

Conclusion

For cystic prolactinomas, tumor size and preoperative PRL levels were independent predictors of early postoperative remission. Preoperative DA therapy combined with TSS may be more beneficial to cystic prolactinoma patients.
The prevalence and contributing risk factors of coronavirus disease 2019 infection in patients with metabolic syndrome
Authors: Bagheri-Hosseinabadi Zahra , Moadab Fatemeh , Amiri Ali , Abbasifard Mitra
Published: May 2023

Background

Components of metabolic syndrome (MetS) was reported to contribute to severe and worse outcomes of coronavirus disease 2019 (COVID-19). Hereby, we evaluated the association of MetS and its components with susceptibility to COVID-19.

Methods

Here, 1000 subjects with MetS were recruited that were diagnosed via the International Diabetes Federation (IDF) criterion. Real-time PCR was exerted to detect SARS-CoV-2 in the nasopharyngeal swabs.

Results

Among the MetS patients, 206 (20.6%) cases were detected to have COVID-19. Smoking (OR = 5.04, 95%CI = 3.53–7.21, P < 0.0001) and CVD (OR = 1.62, 95%CI = 1.09–2.40, P = 0.015) were associated with increased chance of COVID-19 infection in the MetS patients. BMI was significantly higher (P = 0.0001) in MetS cases with COVID-19 than those without COVID-19. Obesity was associated with increased susceptibility to COVID-19 in MetS patients (OR = 2.00, 95%CI = 1.47–2.74, P < 0.0001). Total cholesterol, TG, LDL were significantly higher in the MetS cases with COVID-19 than those without COVID-19. Dyslipidemia was associated with increased chance of COVID-19 (OR = 1.50, 95%CI = 1.10–2.05, P = 0.0104). FBS level was significantly higher in the MetS cases with COVID-19. T2DM was associated with increased risk of COVID-19 in MetS patients (OR = 1.43, 95%CI = 1.01-2.00, P = 0.0384). Hypertension was associated with increased chance of COVID-19 in the MetS patients (OR = 1.44, 95%CI = 1.05–1.98, P = 0.0234).

Conclusions

MetS and its components, like obesity, diabetes, dyslipidemia, cardiovascular complications were associated with increased chance of COVID-19 infection development and probably with aggravated symptoms in such patients.
Association between brachial-ankle pulse wave velocity and microvascular complications in type 2 diabetes mellitus
Authors: Pei Yifei , Shu Yuan , Deng Bo , Liu Yuting
Published: May 2023

Purpose/Aim

To investigate the relationship between brachial-ankle pulse wave velocity (baPWV) and microvascular complications in type 2 diabetes mellitus (T2DM).

Materials and methods

From 2019 to 2021, our hospital enrolled 322 patients with T2DM. Clinical information and biochemical indicators of patients were collected from the inpatient electronic medical record system and analyzed retrospectively. Fundus photography, nerve conduction testing, and sensory threshold measurement were all conducted on the subjects. We measured the pulse wave velocity on both sides of the arm and ankle, then averaged the results. The enrolled cases were divided into two groups based on the baPWV: Group 1 (<the reference cutoff value, n = 160) and Group 2 (≥ the reference cutoff value, n = 162). The association between associated factors and baPWV abnormalities was investigated using a logistic regression model.

Results

Group 2 had higher Systolic Blood Pressure(SBP), Diastolic Blood Pressure (DBP), duration of diabetes, Fasting Plasma Glucose (FPG), Blood Urea Nitrogen (BUN) and Serum Uric Acid (SUA) than group 1 (all p < 0.05). The prevalence of diabetic retinopathy, peripheral neuropathy and nephropathy in group 2 was higher compared to group 1 (p < 0.05). After classifying subjects according to the presence or absence of diabetic complications, we found that the baPWV of the Diabetic Peripheral Neuropathy (DPN) group and Diabetic Nephropathy (DN) group was noticeably higher than that of non-DPN group and non-DN group, respectively (both p < 0.05). The baPWV increased with the aggravation of Diabetic Retinopathy (DR) (p < 0.05). Multivariate logistic regression analysis showed that DBP (OR 1.039, 95%CI 1.010–1.068 p = 0.008), duration of diabetes (OR 1.059, 95%CI 1.017–1.103 p = 0.006), FPG (OR 1.104, 95%CI 1.025–1.188 p = 0.009) and BUN (OR 1.128, 95%CI 1.001–1.270 p = 0.048) were all independently and positively associated with baPWV.

Conclusions

The baPWV is strongly associated with microvascular complications of T2DM. The DBP, duration of diabetes, FPG, and BUN were all independent associated factors of baPWV.
“I wanted information”: navigating breast Cancer and its treatment in Lima, Peru
Authors: Fields Brittany C. , Morse Rachel M. , Ortega Emma , Waterfield Kristen , Prieto Bryn A. , Oberhelman Richard , Paz-Soldán Valerie A.
Published: May 2023

Background

Breast cancer impacts millions of people worldwide, and in Peru, breast cancer is the most common cause of cancer related death among women. Breast cancer treatment is physically and emotionally burdensome and challenging for patients.

Methods

In-depth interviews were conducted with 14 female breast cancer patients and survivors in Lima, Peru. The interviews explored four main themes: the women’s emotional experiences, coping mechanisms, resources available or needed, and advice for newly diagnosed breast cancer patients.

Results

Respondents described a tremendous lack of informational support during and after diagnosis and treatment and requested more of this support from health professionals. Social support groups were helpful to participants; however, these forms of support were not available to all participants. Emotional and esteem support seemed amply received from family and friends, faith organizations, and fellow cancer patients. Participants experienced a range of emotions upon diagnosis and during treatment including fear, anxiety, difficulty accepting bodily changes, loneliness, and denial.

Conclusion

Breast cancer and its treatment can be a long, emotional journey; more extensive forms of informational support could help patients cope with this process.
Association between tissue stress reaction and ACE2/TMPRSS2 expression in endometria of reproductive aged women before and during Covid-19 pandemic
Authors: Ogawa Kanae , Khan Khaleque N. , Koshiba Akemi , Fujishita Akira , Horiguchi Go , Teramukai Satoshi , Itoh Kyoko , Guo Sun-Wei , Mori Taisuke
Published: May 2023

Background

A potential concern has been raised regarding fertility and reproductive outcome during the Covid-19 pandemic with growing stress and anxiety. However, information on the association between tissue stress reaction and expression profiles of SARS-CoV-2 viral entry proteins, ACE2 and TMPRSS2, in endometria collected from women before (pre-pandemic) and during the Covid-19 pandemic (in-pandemic) is unknown. We aim to investigate the relationship between the expression of stress-reactive proteins and of ACE2 and TMPRSS2 in endometria collected from women during these two different time frames.

Methods

We retrospectively retrieved tissue blocks of endometrial samples from 25 women in 2019 (pre-pandemic) and 25 women in 2020 (in-pandemic) who underwent hysterectomy for different gynecological indications. Immunohistochemical analysis was performed with endometrial tissue samples that were collected before and during the pandemic, using respective antibodies targeting ACE2/TMPRSS2, ADRB2 and NK1R (stress and anxiety receptor markers, respectively). The quantification of immunoreactive cells for each marker was calculated by the immunoreactive score (IRS) analysis. This retrospective cohort study was limited to small sample size.

Results

No significant differences in the IRS of ACE2 and TMPRSS2 were found between the endometria that were collected before and during the pandemic with a lack of correlation between ACE2 and TMPRSS2 expression in respective endometria (r = 0.11, pre-pandemic; r = 0.04, in-pandemic). The immunostaining levels of stress marker, ADRB2 were significantly higher in the endometria of in-pandemic group (p = 0.015) comparing to that of pre-pandemic group. Pearson’s correlation coefficient analysis showed a significant correlation in the expression between ADRB2 and TMPRSS2 (r = 0.41, p = 0.042) in the endometria of in-pandemic group but not in the pre-pandemic group.

Conclusion

The rise in stress and anxiety among women during current pandemic may elicit substantial amount of tissue stress reaction with consequent increase in the expression of SARS-CoV-2 viral entry proteins in their endometria. A lack of correlation between ACE2 and TMPRSS2 expression in endometria may reassure women in their reproductive age that they are not more susceptible to infection by SARS-CoV-2 and suggest that stressful women during this pandemic can safely decide to conceive naturally or by artificial reproductive technology.

Published: May 2023

Background

Falls are among the most common and serious adverse events for hospitalised patients. In-hospital falls pose a major medical and economic challenge for public health worldwide. Nevertheless, the issue is often addressed without regard to certain relevant variables such as the time of the fall. The aim of this study was to determine the effect of the implementation of a nurse-led intervention based on the temporal patterns of falls and their aetiology on the occurrence of falls.

Methods

A mixed-method research design was carried out in three phases: a) a longitudinal prospective study (audits, chronobiological analyses and implementation of a multicentre nurse-led intervention based on temporal patterns of falls); b) a retrospective study of fall records; and c) a qualitative study based on focus groups. The protocol was published in 2021.

Results

A difference was observed in the number of fall records before and after the chronopreventive intervention (retrospective: 64.4% vs. 35.6%; p < 0,001). According to the interrupted series analysis, considering the influence of the COVID-19 pandemic, a reduction in falls of 2.96% (95% CI 1.70%-4.17%) was observed. The concepts of falls, the COVID-19 pandemic and the causes of non-registration have emerged as categories for qualitative analysis.

Conclusions

A multicentric nurse-led program based on tailored organisational, educational and behavioural chronopreventive measures seems to lead to a reduction in the number of in-hospital falls. The findings of the present study, highlighting the implementation of chronopreventive measures, can serve as a basis for future health policies.

Trial registration

The project was registered on the Clinical Trials Registry NCT04367298 (29/04/2020).
Development and evaluation of a rehabilitation training compliance scale for patients with urinary incontinence
Authors: Luo Liumei , Chen Xi , Xie Huifang , Zhou Jiaquan , Li Li
Published: May 2023

Background

Urinary incontinence treatment includes conservative treatment, physical devices, medication, and surgery. Pelvic floor muscle training combined with bladder training is among the most effective, non-invasive, and economical ways to treat urinary incontinence, and compliance with training is essential in urinary incontinence treatment. Several instruments assess pelvic floor muscle training and bladder training. However, no tool has been found that assesses compliance with pelvic floor muscle training when combined with bladder training for urinary incontinence. This study aimed to develop a rehabilitation training compliance scale for patients with urinary incontinence and to evaluate its validity and reliability.

Methods

This study was performed in two tertiary hospitals in Hainan, China between December 2020 and July 2021, 123 patients were included. A literature review, group discussions, and two rounds of letter consultations were performed to acquire the item pool and finalise the 12 items for this scale. Exploratory and confirmatory factor analysis, Cronbach’s α, split-half reliability, test–retest reliability, content validity, construct validity, convergent and discriminant validity, and criterion-related validity were used to examine the items in the scale.

Results

A 12-item scale comprising three factors accounted for 85.99% of the variance in the data. The Cronbach’s α, split-half reliability, test–retest reliability, and content validity index of the scale were 0.95, 0.89, 0.86, and 0.93, respectively. Comparison with the Chen pelvic floor muscle exercise self-efficacy scale showed high calibration correlation validity (coefficient = 0.89).

Conclusions

The training compliance scale developed in this study is a valid and reliable measurement tool to assess pelvic floor muscle training and bladder training compliance in patients with urinary incontinence.
Drug shortages in China: a cross-sectional study
Authors: Song Yinyin , Li Jianchun , Zhao Fei , Jin Pengfei
Published: May 2023

Background

Drug shortages significantly threaten public health and medical service provision worldwide. Research evidence on the complete picture of drug shortages is currently scant in China. This study aimed to provide a descriptive overview and a reference for alleviating of drug shortages in China.

Methods

National and provincial lists of drug shortages issued in China from 2018 to 2021 were collected and summarized. The information on essential medicines, medical insurance drugs, emergency drugs, and volume-based purchasing drugs was then matched with a drug shortage list to analyse the characteristics, proportion and incidence of drug shortage on each list based on the analysis of information such as dosage form, shortage frequency, and Anatomical Therapeutic Chemical (ATC) classification of the drugs in shortage.

Results

A total of 24 provinces issued drug shortages lists involving 408 drugs from 2018 to 2021. All 58 drugs in the national drug list were included on the provincial drug shortage list. Among all the drugs in shortage, the most significant shortage involved injections, accounting for 45.3% (185/408). Ninety-five drugs (23.3%) were in shortage 5 times (annual shortage > 1 time) or more in the provincial lists, and 199 drugs (48.8%) were on the shortage list only once. In terms of therapeutic property, nearly all categories of drugs had been reported in shortage, among which cardiovascular drugs, nervous system drugs, anti-tumor and immunomodulatory drugs, and blood and hematopoietic organ drugs accounted for more than 10%. There is no significant difference in drug shortage among economic regions. Comparing drugs in shortage and various lists, 81.9% (334/408), 51.0% (208/408) and 67.9% (277/408) fell on the National Medical Insurance Drug List, National Essential Medicines List, and WHO Model List of Essential Medicines, respectively, while the volume-based purchasing drugs accounted for 3.4% (14 drugs). The incidence of drug shortages on NEML, WHO Model List of Essential Medicines and medical insurance category A was significantly higher than that of medical insurance category B and volume-based purchasing drugs (P < 0.05). Of the Emergency Drugs List, 72.0% (36/50) also experienced shortages, significantly higher than all the above categories (P < 0.05).

Conclusions

In China, drug shortages were severe and complicated. Drug shortages vary among economic regions but are not significant. In comparison, the national procurement pattern of volume-based drug purchasing may be conducive to alleviating the drug shortage problem. Collaboration of all partners was recommended to ensure the supply of clinically necessary drugs.
Implementation of a referral pathway for cancer survivors to access allied health services in the community
Authors: Russell Lahiru , McIntosh Rebecca , Martin Carina , Soo Wee Kheng , Ugalde Anna
Published: May 2023

Background

The growing demands for multidisciplinary cancer survivorship care require new approaches to address the needs of people living after a cancer diagnosis. Good Life–Cancer Survivorship is a self-management support survivorship program delivered by community allied health (AH) services for people diagnosed with cancer. A pilot study established the benefits of Good Life–Cancer Survivorship to help survivors manage their health and wellbeing in the community health setting. This study expanded the program to four community health services and evaluated the implementation outcomes of the referral pathway to the survivorship program.

Methods

Eligible cancer survivors attending hospital oncology services were referred to the survivorship program. Data was collected between 19/02/2021-22/02/2022 and included allied health service utilisation, consumer surveys, and interviews to understand consumer experience with the referral pathway. Interviews and focus groups with hospital and community health professionals explored factors influencing the referral uptake. Implementation outcomes included Adoption, Acceptability, Appropriateness, Feasibility, and Sustainability.

Results

Of 35 eligible survivors (mean age 65.5 years, SD = 11.0; 56% women), 31 (89%) accepted the referral. Most survivors had two (n = 14/31; 45%) or more (n = 11/31; 35%) allied health needs. Of 162 AH appointments (median appointment per survivor = 4; range = 1–15; IQR:5), 142/162 (88%) were scheduled within the study period and 126/142 (89%) were attended. Consumers’ interviews (n = 5) discussed the referral pathway; continuation of survivorship care in community health settings; opportunities for improvement of the survivorship program. Interviews with community health professionals (n = 5) highlighted the impact of the survivorship program; cancer survivorship care in community health; sustainability of the survivorship program. Interviews (n = 3) and focus groups (n = 7) with hospital health professionals emphasised the importance of a trusted referral process; a holistic and complementary model of care; a person-driven process; the need for promoting the survivorship program. All evaluations favourably upheld the five implementation outcomes.

Conclusions

The referral pathway provided access to a survivorship program that supported survivors in self-management strategies through tailored community allied health services. The referral pathway was well adopted and demonstrated acceptability, appropriateness, and feasibility. This innovative care model supports cancer survivorship care delivery in community health settings, with clinicians recommending sustaining the referral pathway.
Conceptualising engagement with HIV care for people on treatment: the Indicators of HIV Care and AntiRetroviral Engagement (InCARE) Framework

Published: May 2023

Background

As the crisis-based approach to HIV care evolves to chronic disease management, supporting ongoing engagement with HIV care is increasingly important to achieve long-term treatment success. However, ‘engagement’ is a complex concept and ambiguous definitions limit its evaluation. To guide engagement evaluation and development of interventions to improve HIV outcomes, we sought to identify critical, measurable dimensions of engagement with HIV care for people on treatment from a health service-delivery perspective.

Methods

We used a pragmatic, iterative approach to develop a framework, combining insights from researcher experience, a narrative literature review, framework mapping, expert stakeholder input and a formal scoping review of engagement measures. These inputs helped to refine the inclusion and definition of important elements of engagement behaviour that could be evaluated by the health system.

Results

The final framework presents engagement with HIV care as a dynamic behaviour that people practice rather than an individual characteristic or permanent state, so that people can be variably engaged at different points in their treatment journey. Engagement with HIV care for those on treatment is represented by three measurable dimensions: ‘retention’ (interaction with health services), ‘adherence’ (pill-taking behaviour), and ‘active self-management’ (ownership and self-management of care). Engagement is the product of wider contextual, health system and personal factors, and engagement in all dimensions facilitates successful treatment outcomes, such as virologic suppression and good health. While retention and adherence together may lead to treatment success at a particular point, this framework hypothesises that active self-management sustains treatment success over time. Thus, evaluation of all three core dimensions is crucial to realise the individual, societal and public health benefits of antiretroviral treatment programmes.

Conclusions

This framework distils a complex concept into three core, measurable dimensions critical for the maintenance of engagement. It characterises elements that the system might assess to evaluate engagement more comprehensively at individual and programmatic levels, and suggests that active self-management is an important consideration to support lifelong optimal engagement. This framework could be helpful in practice to guide the development of more nuanced interventions that improve long-term treatment success and help maintain momentum in controlling a changing epidemic.
Recent expansion of metabolic versatility in Diplonema papillatum, the model species of a highly speciose group of marine eukaryotes

Published: May 2023

Background

Diplonemid flagellates are among the most abundant and species-rich of known marine microeukaryotes, colonizing all habitats, depths, and geographic regions of the world ocean. However, little is known about their genomes, biology, and ecological role.

Results

We present the first nuclear genome sequence from a diplonemid, the type species Diplonema papillatum. The ~ 280-Mb genome assembly contains about 32,000 protein-coding genes, likely co-transcribed in groups of up to 100. Gene clusters are separated by long repetitive regions that include numerous transposable elements, which also reside within introns. Analysis of gene-family evolution reveals that the last common diplonemid ancestor underwent considerable metabolic expansion. D. papillatum-specific gains of carbohydrate-degradation capability were apparently acquired via horizontal gene transfer. The predicted breakdown of polysaccharides including pectin and xylan is at odds with reports of peptides being the predominant carbon source of this organism. Secretome analysis together with feeding experiments suggest that D. papillatum is predatory, able to degrade cell walls of live microeukaryotes, macroalgae, and water plants, not only for protoplast feeding but also for metabolizing cell-wall carbohydrates as an energy source. The analysis of environmental barcode samples shows that D. papillatum is confined to temperate coastal waters, presumably acting in bioremediation of eutrophication.

Conclusions

Nuclear genome information will allow systematic functional and cell-biology studies in D. papillatum. It will also serve as a reference for the highly diverse diplonemids and provide a point of comparison for studying gene complement evolution in the sister group of Kinetoplastida, including human-pathogenic taxa.
Insights into the formation and diversification of a novel chiropteran wing membrane from embryonic development
Authors: Anthwal Neal , Urban Daniel J. , Sadier Alexa , Takenaka Risa , Spiro Simon , Simmons Nancy , Behringer Richard R. , Cretekos Chris J. , Rasweiler John J. , Sears Karen E.
Published: May 2023

Background

Through the evolution of novel wing structures, bats (Order Chiroptera) became the only mammalian group to achieve powered flight. This achievement preceded the massive adaptive radiation of bats into diverse ecological niches. We investigate some of the developmental processes that underlie the origin and subsequent diversification of one of the novel membranes of the bat wing: the plagiopatagium, which connects the fore- and hind limb in all bat species.

Results

Our results suggest that the plagiopatagium initially arises through novel outgrowths from the body flank that subsequently merge with the limbs to generate the wing airfoil. Our findings further suggest that this merging process, which is highly conserved across bats, occurs through modulation of the programs controlling the development of the periderm of the epidermal epithelium. Finally, our results suggest that the shape of the plagiopatagium begins to diversify in bats only after this merging has occurred.

Conclusions

This study demonstrates how focusing on the evolution of cellular processes can inform an understanding of the developmental factors shaping the evolution of novel, highly adaptive structures.

Background

In recent years, the downward trajectory of malaria transmission has slowed and, in some places, reversed. New tools are needed to further reduce malaria transmission. One approach that has received recent attention is a novel house-based intervention comprising window screening (S) and general house repairs to make the house more mosquito proof, together with EaveTubes (ET) that provide an innovative way of targeting mosquitoes with insecticides as they search for human hosts at night. The combined approach of Screening + EaveTubes (SET) essentially turns the house into a ‘lure and kill’ device.

Methods

This study evaluated the impact of SET on malaria infection prevalence in Côte d’Ivoire and compares the result in the primary outcome, malaria case incidence. Malaria infection prevalence was measured in a cross-sectional survey in 40 villages, as part of a cluster-randomised trial evaluating the impact of SET on malaria case incidence.

Results

Infection prevalence, measured by rapid diagnostic test (RDT), was 50.4% and 36.7% in the control arm and intervention arm, respectively, corresponding to an odds ratio of 0.57 (0.45–0.71), p < 0.0001). There was moderate agreement between RDT and microscopy results, with a reduction in odds of infection of 36% recorded when infection was measured by microscopy. Prevalence measured by RDT correlated strongly with incidence at a cluster level.

Conclusions

In addition to reducing malaria case incidence, house screening and EaveTubes substantially reduced malaria infection prevalence 18 months after installation. Infection prevalence may be a good metric to use for evaluating malaria interventions in areas of similar transmission levels to this setting.

Spatiotemporal analysis of the effect of global development indicators on child mortality
Authors: Amegbor Prince M. , Addae Angelina
Published: May 2023

Background

Child mortality continue to be a major public health issue in most developing countries; albeit there has been a decline in global under-five deaths. The differences in child mortality can best be explained by socioeconomic and environmental inequalities among countries. In this study, we explore the effect of country-level development indicators on under-five mortality rates. Specifically, we examine potential spatio-temporal heterogeneity in the association between major world development indicators on under-five mortality, as well as, visualize the global differential time trend of under-five mortality rates.

Methods

The data from 195 countries were curated from the World Bank’s World Development Indicators (WDI) spanning from 2000 to 2017 and national estimates for under-five mortality from the UN Inter-agency Group for Child Mortality Estimation (UN IGME).We built parametric and non-parametric Bayesian space-time interaction models to examine the effect of development indicators on under-five mortality rates. We also used employed Bayesian spatio-temporal varying coefficient models to assess the spatial and temporal variations in the effect of development indicators on under-five mortality rates.

Results

In both parametric and non-parametric models, the results show indicators of good socioeconomic development were associated with a reduction in under-five mortality rates while poor indicators were associated with an increase in under-five mortality rates. For instance, the parametric model shows that gross domestic product (GDP) (β = − 1.26, [CI − 1.51; − 1.01]), current healthcare expenditure (β = − 0.40, [CI − 0.55; − 0.26]) and access to basic sanitation (β = − 0.03, [CI − 0.05; − 0.01]) were associated with a reduction under-five mortality. An increase in the proportion practising open defecation (β = 0.14, [CI 0.08; 0.20]) an increase under-five mortality rate. The result of the spatial components spatial variation in the effect of the development indicators on under-five mortality rates. The spatial patterns of the effect also change over time for some indicators, such as PM2.5.

Conclusion

The findings show that the burden of under-five mortality rates was considerably higher among sub-Saharan African countries and some southern Asian countries. The findings also reveal the trend in reduction in the sub-Saharan African region has been slower than the global trend.
Snail mediates GDF-8-stimulated human extravillous trophoblast cell invasion by upregulating MMP2 expression

Background

Extravillous trophoblast (EVT) cell invasion is a tightly regulated process that requires for a normal pregnancy. The epithelial-mesenchymal transition (EMT) has been implicated in EVT cell invasion. Growth differentiation factor-8 (GDF-8), a member of the transforming growth factor-beta (TGF-β) superfamily, is expressed in the human placenta and promotes EVT cell invasion by upregulating the expression of matrix metalloproteinase 2 (MMP2). However, the underlying molecular mechanism of GDF-8-induced MMP2 expression remains undetermined. Therefore, the present study aims to examine the role of Snail and Slug, the EMT-related transcriptional regulators, in GDF-8-stimulated MMP2 expression and cell invasion in HTR-8/SVneo human EVT cell line and primary cultures of human EVT cells.

Methods

HTR-8/SVneo and primary cultures of human EVT cells were used to examine the effect of GDF-8 on MMP2 expression and explore the underlying mechanism. For gene silencing and overexpression, the HTR-8/SVneo cell line was used to make the experiments more technically feasible. The cell invasiveness was measured by Matrigel-coated transwell invasion assay.

Results

GDF-8 stimulated MMP2 expression in both HTR-8/SVneo and primary EVT cells. The stimulatory effect of GDF-8 on MMP2 expression was blocked by the inhibitor of TGF-β type-I receptors, SB431542. Treatment with GDF-8 upregulated Snail and Slug expression in both HTR-8/SVneo and primary EVT cells. The stimulatory effects of GDF-8 on Snail and Slug expression were blocked by pretreatment of SB431542 and siRNA-mediated knockdown of SMAD4. Interestingly, using the siRNA knockdown approach, our results showed that Snail but not Slug was required for the GDF-8-induced MMP2 expression and cell invasion in HTR-8/SVneo cells. The reduction of MMP2 expression in the placentas with preeclampsia (PE) was also observed.

Conclusions

These findings discover the physiological function of GDF-8 in the human placenta and provide important insights into the regulation of MMP2 expression in human EVT cells.
KLF4-mediated upregulation of the NKG2D ligand MICA in acute myeloid leukemia: a novel therapeutic target identified by enChIP

The immunoreceptor NKG2D, which is expressed on NK cells and T cell subsets is critically involved in tumor immune surveillance. This applies in particular to acute myeloid leukemia (AML), which evades immune detection by downregulation of NKG2D ligands (NKG2D-L), including MICA. The absence of NKG2D-L on AML cells is moreover associated with leukemia stem cell characteristics. The NKG2D/NKG2D-L system thus qualifies as an interesting and promising therapeutic target.

Here we aimed to identify transcription factors susceptible to pharmacological stimulation resulting in the expression of the NKG2D-L MICA in AML cells to restore anti-tumor activity. Using a CRISPR-based engineered ChIP (enChIP) assay for the MICA promoter region and readout by mass spectrometry-based proteomics, we identified the transcription factor krüppel-like factor 4 (KLF4) as associated with the promoter. We demonstrated that the MICA promoter comprises functional binding sites for KLF4 and genetic as well as pharmacological gain- and loss-of-function experiments revealed inducible MICA expression to be mediated by KLF4.

Furthermore, induction in AML cells was achieved with the small compound APTO253, a KLF4 activator, which also inhibits MYC expression and causes DNA damage. This induction in turn yielded increased expression and cell surface presentation of MICA, thus rendering AML cells more susceptible to NK cell-mediated killing. These data unravel a novel link between APTO253 and the innate anti-tumor immune response providing a rationale for targeting AML cells via APTO253-dependent KFL4/MICA induction to allow elimination by endogenous or transplanted NK and T cells in vivo.

The higher prevalence of metabolic syndrome (MetS) in women after menopause is associated with a decrease in circulating 17β-oestradiol. To explore novel treatments for MetS in women with oestrogen deficiency, we studied the effect of exogenous butyrate on diet-induced obesity and metabolic dysfunctions using ovariectomized (OVX) mice as a menopause model. Oral administration of sodium butyrate (NaB) reduced the body fat content and blood lipids, increased whole-body energy expenditure, and improved insulin sensitivity. Additionally, NaB induced oestrogen receptor alpha (ERα) expression, activated the phosphorylation of AMPK and PGC1α, and improved mitochondrial aerobic respiration in cultured skeletal muscle cells. In conclusion, oral NaB improves metabolic parameters in OVX mice with diet-induced obesity. Oral supplementation with NaB might provide a novel therapeutic approach to treating MetS in women with menopause.
