Abstract
Background
Cross-sectional evidence indicates that certain personality traits may influence how well people with dementia and their caregivers are able to live alongside the condition. However, no studies to date have explored these associations longitudinally. The present study aimed to explore whether each of the Five-Factor personality traits were associated with change over two years in perceptions of ‘living well’ for people with dementia and their caregivers. ‘Living well’ was conceptualized as a composite of quality of life, satisfaction with life, and subjective well-being.

Methods
Data were analyzed from 1487 people with dementia and 1234 caregivers who took part in the IDEAL cohort. Participants were categorized into low, medium, and high groups for each trait using stanine scores. Latent growth curve models investigated associations between these groups and ‘living well’ scores for each trait at baseline and at 12 and 24 months. Covariates included cognition in people with dementia and stress in caregivers. A Reliable Change Index was calculated against which to evaluate changes in ‘living well’ scores over time.

Results
At baseline, neuroticism was negatively associated with ‘living well’ scores for people with dementia, while conscientiousness, extraversion, openness, and agreeableness were positively associated. For caregivers, neuroticism was negatively associated with ‘living well’ scores at baseline while conscientiousness and extraversion were positively associated. ‘Living well’ scores were mostly stable over time with no influence of personality traits on observed changes.

Conclusions
Findings suggest that personality traits, particularly neuroticism, have a meaningful impact on how people with dementia and caregivers rate their capability to ‘live well’ at baseline. Over time ‘living well’ scores for each personality trait group were largely stable. Studies utilizing longer follow-up periods and more appropriate measures of personality are needed to corroborate and extend the findings of the present study.

Abstract
Background
Caesarean section (CS) rates are rising. Shared decision making (SDM) is a component of patient-centered communication which requires adequate information and awareness. Women in Ghana have varying perceptions about the procedure. We sought to explore mothers’ knowledge. perceptions and SDM-influencing factors about CSs.

Methods
A transdisciplinary mixed-methods study was conducted at the maternity unit of Korle-Bu Teaching Hospital in Accra, Ghana from March to May, 2019. Data collection was done in four phases: in-depth interviews (n = 38), pretesting questionnaires (n = 15), three focus group discussions (n = 18) and 180 interviewer administered questionnaires about SDM preferences. Factors associated with SDM were analyzed using Pearson’s Chi-square test and multiple logistic regression.

Results
Mothers depicted a high level of knowledge regarding medical indications for their CS but had low level of awareness of SDM. The perception of a CS varied from dangerous, unnatural and taking away their strength to a life-saving procedure. The mothers had poor knowledge about pain relief in labour and at Caesarean section. Health care professionals attributed the willingness of mothers to be involved in SDM to their level of education. Husbands and religious leaders are key stakeholders in SDM. Insufficient consultation time was a challenge to SDM according to health care professionals and post-partum mothers. Women with parity ≥ 5 have a reduced desire to be more involved in shared decision making for Caesarean section. AOR = 0.09, CI (0.02–0.46).

Conclusion
There is a high knowledge about the indications for CS but low level of awareness of and barriers to SDM. The fewer antenatal care visits mothers had, the more likely they were to desire more involvement in decision making. Aligned to respectful maternity care principles, greater involvement of pregnant women and their partners in decision making process could contribute to a positive pregnancy experience. Education, including religious leaders and decision- making tools could contribute to the process of SDM.

Published: June 2023

Abstract
Background
Cancer cachexia, occurring in ~ 80% pancreatic cancer (PC) patients overall, is a paraneoplastic syndrome mediated by cancer-induced systemic inflammation and characterized by weight loss and skeletal muscle wasting. Identifying clinically relevant PC-derived pro-inflammatory factors with cachexigenic potential may provide novel insights and therapeutic strategies.

Methods
Pro-inflammatory factors with cachexigenic potential in PC were identified by bioinformatic analysis. The abilities of selected candidate factors in inducing skeletal muscle atrophy were investigated. Expression levels of candidate factors in tumors and sera was compared between PC patients with and without cachexia. Associations between serum levels of the candidates and weight loss were assessed in PC patients.

Results
S100A8, S100A9, and S100A8/A9 were identified and shown to induce C2C12 myotube atrophy. Tumors of PC patients with cachexia had markedly elevated expression of S100A8 (P = 0.003) and S100A9 (P < 0.001). PC patients with cachexia had significantly higher serum levels of S100A8, S100A9 and S100A8/A9. Serum levels of these factors positively correlated with percentage of weight loss [correlation coefficient: S100A8: 0.33 (P < 0.001); S100A9: 0.30 (P < 0.001); S100A8/A9: 0.24 (P = 0.004)] and independently predicted the occurrence of cachexia [adjusted odds ratio (95% confidence interval) per 1ng/ml increase: S100A8 1.11 (1.02–1.21), P = 0.014; S100A9 1.10 (1.04–1.16), P = 0.001; per 1 µg/ml increase: S100A8/A9 1.04 (1.01–1.06), P = 0.009].

Conclusions
Atrophic effects of S100A8, S100A9, and S100A8/A9 indicated them as potential pathogenic factors of PC-induced cachexia. In addition, the correlation with the degree of weight loss and prediction of cachexia in PC patients implicated their potential utility in the diagnosis of PC-induced cachexia.

Published: June 2023

Abstract
Background
This study aimed to report eleven cases of non-neovascular pachychoroid disease with hyperreflective material (HRM) that occurred in Japanese patients.

Methods
A retrospective review of data from eleven patients who had non-neovascular retinal pigment epithelium (RPE) protrusion with HRM in the neurosensory retina between March 2017 and June 2022 was conducted. Clinical examination, color fundus photography, fluorescein angiography, spectral-domain optical coherence tomography (SD-OCT), and OCT angiography data were analyzed. Main outcome measures were patient characteristics, changes in SD-OCT findings, and symptom outcomes.

Results
All cases had RPE protrusion and HRM with dilated choroidal veins, which were characteristic of pachychoroid disease. However, none of the cases had macular neovascularization (MNV). In 9 eyes (81.8%), HRM improved spontaneously without intervention and resulted in alterations in RPE, referred to as pachychoroid pigment epitheliopathy (PPE) or focal choroidal excavation (FCE). In these cases, symptoms such as metamorphopsia and distortion improved without treatment. In the remaining two cases (18.2%), HRM still persisted during the follow-up period.

Conclusion
There are some cases of non-neovascular pachychoroid disorder with HRM, which might be a new entity of pachychoroid spectrum disease or an early stage of PPE or FCE. These cases should not be misdiagnosed as MNV, and careful observation is necessary.
Meaningful Activities and Recovery (MA&R): a co-led peer occupational therapy intervention for people with psychiatric disabilities. Results from a randomized controlled trial
Authors: Bjørkedal Siv-Therese Bogevik , Bejerholm Ulrika , Hjorthøj Carsten , Møller Tom , Eplov Lene Falgaard 
Published: June 2023

Abstract
Background
Activity and participation are critical to health and wellbeing. Limited evidence exists on how to support people with mental illness in participating in everyday activities.

Aim
To investigate the effectiveness of Meaningful Activities and Recovery (MA&R), a co-led peer occupational therapy intervention focusing on activity engagement, functioning, quality of life, and personal recovery.

Methods
In a statistician blinded, multicenter RCT including 139 participants from seven community and municipal mental health services in Denmark, participants were randomly assigned to 1) MA&R and standard mental health care or 2) standard mental health care. The MA&R intervention lasted 8 months and consisted of 11 group sessions, 11 individual sessions, and support to engage in activities. The primary outcome, activity engagement, was measured using Profile of Occupational Engagement in People with Severe Mental Illness (POES-S). Outcomes were measured at baseline and post-intervention follow-up.

Results
Meaningful Activities and Recovery was delivered with high fidelity and 83% completed the intervention. It did not demonstrate superiority to standard mental health care, as intention-to treat analysis revealed no significant differences between the groups in activity engagement or any of the secondary outcomes.

Conclusion
We did not find positive effects of MA&R, possibly because of COVID-19 and related restrictions. Fidelity assessments and adherence rates suggest that MA&R is feasible and acceptable. However, future studies should focus on refining the intervention before investigating its effectiveness.

Trial registration
The trial was registered 24/05/2019 at ClinicalTrials.gov NCT03963245.
Socioeconomic disparities and concentration of the spread of the COVID-19 pandemic in the province of Quebec, Canada
Authors: Lefebvre Gabrielle , Haddad Slim , Moncion-Groulx Dominique , Saint-Onge Mélanie , Dontigny André 
Published: June 2023

Abstract
Background
Recent studies suggest that the risk of SARS-CoV-2 infection may be greater in more densely populated areas and in cities with a higher proportion of persons who are poor, immigrant, or essential workers. This study examines spatial inequalities in SARS-CoV-2 exposure in a health region of the province of Quebec in Canada.

Methods
The study was conducted on the 1206 Canadian census dissemination areas in the Capitale-Nationale region of the province of Quebec. The observation period was 21 months (March 2020 to November 2021). The number of cases reported daily in each dissemination area was identified from available administrative databases. The magnitude of inequalities was estimated using Gini and Foster-Greer-Thorbecke (FGT) indices. The association between transmission and socioeconomic deprivation was identified based on the concentration of transmission in socially disadvantaged areas and on nonparametric regressions relating the cumulative incidence rate by area to ecological indicators of spatial disadvantage. Quantification of the association between median family income and degree of exposure of dissemination areas was supplemented by an ordered probit multiple regression model.

Results
Spatial disparities were elevated (Gini = 0.265; 95% CI [0.251, 0.279]). The spread was more limited in the less densely populated areas of the Quebec City agglomeration and outlying municipalities. The mean cumulative incidence in the subsample made up of the areas most exposed to the pandemic was 0.093. The spread of the epidemic was concentrated in the most disadvantaged areas, especially in the densely populated areas. Socioeconomic inequality appeared early and increased with each successive pandemic wave. The models showed that areas with economically disadvantaged populations were three times more likely to be among the areas at highest risk for COVID-19 (RR = 3.55; 95% CI [2.02, 5.08]). In contrast, areas with a higher income population (fifth quintile) were two times less likely to be among the most exposed areas (RR = 0.52; 95% CI [0.32, 0.72]).

Conclusion
As with the H1N1 pandemics of 1918 and 2009, the SARS-CoV-2 pandemic revealed social vulnerabilities. Further research is needed to explore the various manifestations of social inequality in relation to the pandemic.

Abstract
Background
People experiencing homelessness (PEH) are at increased risk for acquiring SARS-CoV-2, but the burden of long COVID in this population is unknown.

Methods
We conducted a matched prospective cohort study to assess the prevalence, characteristics, and impact of long COVID among sheltered PEH in Seattle, WA between September 2020—April 2022. Adults ≥ 18 years, residing across nine homeless shelters with active respiratory virus surveillance, were eligible to complete in-person baseline surveys and interval follow-up phone surveys. We included a subset of 22 COVID-19-positive cases who tested positive or inconclusive for SARS-CoV-2 and 44 COVID-19-negative controls who tested negative for SARS-CoV-2, frequency matched on age and sex. Among controls, 22 were positive and 22 were negative for one of 27 other respiratory virus pathogens. To assess the impact of COVID-19 on the risk of symptom presence at follow-up (day 30–225 post-enrollment test), we performed log-linear regression with robust standard errors, adjusting for confounding by shelter site and demographic variables determined a priori.

Results
Of 53 eligible COVID-19 cases, 22 (42%) completed ≥ 1 follow-up survey. While five (23%) cases reported ≥ 1 symptom at baseline, this increased to 77% (10/13) between day 30–59 and 33% (4/12) day 90 + . The most commonly reported symptoms day 30 + were fatigue (27%) and rhinorrhea (27%), with 8 (36%) reporting symptoms that interfered with or prevented daily activities. Four (33%) symptomatic cases reported receiving medical care outside of a medical provider at an isolation facility. Of 44 controls, 12 (27%) reported any symptoms day 90 + . Risk of any symptoms at follow-up was 5.4 times higher among COVID-19 cases compared to controls (95% CI: 2.7–10.5).

Conclusions
Shelter residents reported a high prevalence of symptoms 30 + days after their SARS-CoV-2 detection, though few accessed medical care for persistent illness. The impact of COVID-19 extends beyond acute illness and may exacerbate existing challenges that marginalized populations face in maintaining their health and wellbeing.

Abstract
Introduction
Lower respiratory tract infections (LRTIs) caused by drug-resistant pathogenic bacteria is a major problem in developing countries including Ethiopia. Therefore, this study aimed to determine the pathogenic bacteria and their antimicrobial susceptibility patterns among Gene X-pert tuberculosis-negative adult patients with clinically suspected LRTIs at the University of Gondar Comprehensive Specialized Referral Hospital, Gondar, Northwest Ethiopia.

Methods
This institutional-based cross-sectional study was conducted from February 01 to March 15, 2020. Socio-demographic data were collected by using a structured questionnaire. A total of 254 sputum specimens were collected from Gene X-pert tuberculosis-negative patients. Bacterial recovery was performed using blood, chocolate, and MacConkey agar plates. Bacterial isolates were identified based on Gram staining, colony characteristics, and biochemical reactions. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disk diffusion method. Methicillin resistance of S. aureus was confirmed using cefoxitin (30 µg). Descriptive statistics were calculated for each variable and results are shown in tables and figures.

Results
In this study, the overall sputum culture positivity rate was 145/254 (57.1%). Gram-negative bacteria 111 (64.9%) were predominant compared to Gram-positive bacteria 60 (35.1%). Of the 145 culture-positive cases, 26 (14.8%) had poly-bacterial infections. S. aureus 40 (66.7%) was the predominant Gram-positive bacterium whereas K. pneumoniae 33 (29.7%), was the most isolated Gram-negative bacterium. Bacterial species, such as S. aureus were sensitive to ciprofloxacin 38/40 (95.0%), gentamicin 37/40 (92.5%), cefoxitin 36/40 (90.0%), and clindamycin 34/40 (85.0%). The proportion of Methicillin-resistant S. aureus was low, 4(10.0%). S. pneumoniae was sensitive to chloramphenicol 8/9 (88.9%) and resistant to ciprofloxacin 6/9 (66.7%). K pneumoniae, P. aeruginosa, E. coli, Serratia species, and H. influenzae also demonstrated high levels of resistance to ampicillin at rates of 21/33 (63.6%), 8/8 (100.0%), 15/17 (88.2%), 7/10 (70.0%), and 6/6 (100.0%), respectively.

Conclusion
This study revealed a higher burden of Gram-negative and Gram-positive pathogenic bacterial agents, which is responsible for LRTs. Therefore, routine sputum culture identification and antibiotic susceptibility testing should be performed in Gene X-pert tuberculosis-negative patients.
Co-inhibition of TIGIT and PD-1/PD-L1 in Cancer Immunotherapy: Mechanisms and Clinical Trials

Published: June 2023

AbstractOver the past decade, immune checkpoint inhibitors (ICIs) have emerged as a revolutionary cancer treatment modality, offering long-lasting responses and survival benefits for a substantial number of cancer patients. However, the response rates to ICIs vary significantly among individuals and cancer types, with a notable proportion of patients exhibiting resistance or showing no response. Therefore, dual ICI combination therapy has been proposed as a potential strategy to address these challenges. One of the targets is TIGIT, an inhibitory receptor associated with T-cell exhaustion. TIGIT has diverse immunosuppressive effects on the cancer immunity cycle, including the inhibition of natural killer cell effector function, suppression of dendritic cell maturation, promotion of macrophage polarization to the M2 phenotype, and differentiation of T cells to regulatory T cells. Furthermore, TIGIT is linked with PD-1 expression, and it can synergize with PD-1/PD-L1 blockade to enhance tumor rejection. Preclinical studies have demonstrated the potential benefits of co-inhibition of TIGIT and PD-1/PD-L1 in enhancing anti-tumor immunity and improving treatment outcomes in several cancer types. Several clinical trials are underway to evaluate the safety and efficacy of TIGIT and PD-1/PD-L1 co-inhibition in various cancer types, and the results are awaited. This review provides an overview of the mechanisms of TIGIT and PD-1/PD-L1 co-inhibition in anti-tumor treatment, summarizes the latest clinical trials investigating this combination therapy, and discusses its prospects. Overall, co-inhibition of TIGIT and PD-1/PD-L1 represents a promising therapeutic approach for cancer treatment that has the potential to improve the outcomes of cancer patients treated with ICIs.

The meeting provided a highly interactive forum for scientific discussion, cultural exchange, and collaborations between international scientists working in diverse areas of mitochondrial biology, cell death, and cancer. The two-day symposium attracted more than 180 delegates that included leading international scientists, early career researchers in India, as well as postdoctoral fellows and students. Several of the students, postdoctoral fellows, and junior faculty presented platform talks and had a chance to showcase the depth and emerging progress in biomedical research in India. The meeting will be instrumental for planning future congresses and symposium throughout India, not only to focus on mitochondrial biology, cell death and cancer but to foster continued ferment and collaborations in the biological sciences throughout India.
Translation of the mental health literacy questionnaire for young adults into Chichewa for use in Malawi: preliminary validation and reliability results

Published: June 2023

Abstract
Background
Mental Health Literacy (MHL) is the ability to recognise mental disorders, have knowledge of professional help available, effective self-help strategies, skills to give support to others, and knowledge of how to prevent mental disorders. Sufficient MHL is linked to better help seeking behaviour and management of mental illness. Assessing MHL importantly helps identify knowledge gaps and inaccurate beliefs about mental health issues, whilst informing development and better evaluation of MHL interventions. This study aimed to translate the English version of a self-reporting Mental Health Literacy questionnaire (MHLq) for young adult populations (16–30 years-old) into Chichewa for use in Malawi and evaluate the psychometric properties of this Chichewa version.

Methods
An established translation methodology was employed, involving back-translation, comparison, forward-translation, comparison, and piloting. The translated Chichewa questionnaire was initially piloted with 14 young adults in a Malawi university, then subsequently administered to 132 young adults in rural community settings across Malawi.

Results
Overall internal consistency of the Chichewa translated MHLq was good (Cronbach’s alpha = 0.67) although subscales’ scores ranged from acceptable (factor 1 and 3) to unacceptable (factor 2 and 4). Confirmatory factor analysis found Factor 1 (Knowledge of mental health problems), Factor 3 (First aid skills and help seeking behaviour) and Factor 4 (Self-help strategies) of the Chichewa version fit very well with related factors of the original English MHLq. For Factor 2 (Erroneous beliefs/stereotypes), 5 out of its 8 items correlated well with the original version. This suggests a four-factor solution is a reasonably good fit to the data.

Conclusions
Use of the Malawian MHLq among Chichewa speaking young adult populations is well supported for factors 1 and 3 but not for factors 2 and 4. More psychometric testing with a larger sample is vital to further validate the questionnaire. Further research is needed to carry out test/re-test reliability statistics.
