Cervical cancer screening outcomes in public health facilities in three states in Nigeria.

BACKGROUND: Cervical cancer continues to generate a significant burden of disease and death in low- and middle-income countries (LMICs). Lack of awareness and poor access to early screening and pre-cancer treatment contribute to the high mortality. We describe here cervical cancer screening outcomes in public health facilities in three states in Nigeria. METHODS: We conducted an observational study in 177 government health facilities in Lagos, Kaduna, and Rivers State, Nigeria from January to December 2021, in which we reviewed programmatic data collected through the newly introduced Cervical Cancer Prevention Program. Women who received screening and provided consent were enrolled into the study. Data were extracted from registers in the health facilities using SurveyCTO and descriptive statistical analysis was conducted using StataSE 15 (StataCorp, College Station, TX, USA). RESULTS: Eighty-three thousand, five hundred ninety-three women were included in the analysis including 6,043 (7%) WLHIV. 67,371 (81%) received VIA as their primary screening while 16,173 (19%) received HPV DNA testing, with 49 (< 1%) receiving both at the same time. VIA positivity was 7% for WLHIV and 3% for general population, while HPV prevalence was 16% for WLHIV and 8% for general population. Following a positive HPV result, 21% of women referred, completed triage examination. 96% of women identified with precancerous lesions, received treatment. 44% of women with suspected cancer were successfully referred to an oncology center for advanced treatment. Following treatment with thermal ablation, seven adverse events were reported. CONCLUSIONS: The Program has successfully increased women's access to screening and treatment of precancerous lesions. Almost all women who were eligible for pre-cancerous lesion treatment received it, often on the same day when screened using VIA. However, for women referred for a triage exam or due to suspected cancer, many did not complete their referral visits. More effort is required to ensure HPV positive women and women with suspected cancer are adequately linked to care to further reduce morbidity and mortality associated with cervical cancer in Nigeria. Implementation studies should be conducted to provide insights to improve the utilization of the existing centralized and point of care (POC) platforms to facilitate same day results, and to improve triage and treatment rates.

Abdominal Imaging Findings in Laboratory-Confirmed COVID-19 Patients: A Retrospective Observational Study.

BACKGROUND AND AIM: Coronavirus disease 2019 (CO-VID-19) is known to predominantly present with respiratory symptoms; however, a significant proportion of patients present with digestive symptoms. These symptoms are often non-specific and as such prompt the treating physician to request further imaging evaluation. Understanding the abdominal imaging findings in COVID-19 and their possible associations is thus crucial to direct patient care and prevent misdiagnosis. The aim of this study was to describe abdominal imaging findings on both computed tomography (CT) and ultrasound scans in cases with positive COVID-19 polymerase chain reaction (PCR) tests performed at our institution, and also, to evaluate the reason for requesting these imaging studies, and to correlate these findings with patients' demographics. METHODS: A retrospective observational study was conducted at Salmaniya Medical Complex, Bahrain, between February 2021 and March 2022. We examined the abdominal CT and ultrasound data for PCR-confirmed COVID-19 patients. The demographic data, reason for requesting imaging and imaging findings were gathered by reviewing the hospital's electronic health records and picture archiving and communicating system (PACS). RESULTS: The study included 97 patients, with the majority being male (57.7%). The most common reason for imaging was abdominal pain, as seen in over half of the patients (60.8%), followed by deranged liver enzymes (18.6%). More than 75% of imaging studies showed positive abdominal findings with the majority (19.6%) showing non-specific inflammatory findings, followed by gallbladder disease (13.4%). The CT studies were more likely to yield positive findings as compared to ultrasound, with only 7 (11.3%) CT scans yielding normal findings (χ2 = 14.65; P < 0.01). CONCLUSION: To our knowledge, the research conducted on the abdominal manifestations of COVID-19 is still limited, especially in our region. Our study showed that there are variable presentations of abdominal organ involvement in COVID-19 cases, and as such more data is required to direct choice of imaging study, protocol, and interpretation of findings to better guide patient management.

Incidence and Risk Factors for 28 Days Hospital Readmission: A Retrospective Study from Oman.

Objectives: We sought to evaluate the incidence of 28-day hospital readmission in a tertiary hospital in Oman and identify potential factors associated with increased risk of hospital readmission. Methods: We conducted a retrospective study of all adult patients (≥ 18 years) admitted under the care of the General Internal Medicine unit from 1 June to 31 December 2020 at Sultan Qaboos University Hospital. Elective admissions and COVID-19 infection-related admission were excluded from the study. Results: There were 200 patients admitted during the study period. The mean age was 58.6±19.3 years, and 106 (53.0%) patients were males. Forty-eight (24.0%) patients had unplanned readmission within 28-days after discharge from the hospital. Patients with 28 days unplanned readmission were older (66.6 vs. 56.0 years, p < 0.001) and had a longer length of hospital stay (6.0 vs. 4.0 days, p < 0.001). Also, hypertension (77.1% vs. 55.3%, p =0.007), diabetes mellitus (64.6% vs. 48.0%, p =0.045), and comorbidity (≥ 3 comorbidities, [43.8% vs. 23.8%, p =0.005]) were more prevalent in the unplanned readmission group. Patients with poor functional status (43.7% vs. 26.3%, p < 0.001), requiring feeding tube (25.0% vs. 5.3%, p < 0.001), and with polypharmacy (75.0% vs. 50.0%, p =0.003) were at increased risk of readmission. Conclusions: 28-day hospital readmission is prevalent in our health care setting. Old age, polypharmacy, comorbidities, and poor functional status were associated with an increased risk of hospital readmission. Therefore, evidence-based interventions must be implemented in our health care system to minimize the risk of hospital readmission.

The inhibitory effect of boric acid on hypoxia-regulated tumour-associated carbonic anhydrase IX.

Carbonic anhydrases (EC 4.2.1.1) catalyse the reversible hydration of CO2 into bicarbonate and protons. As a hypoxia-sensitive and tumour-associated isoform, isoform CA IX, is significantly overexpressed in various malignancies, being a validated target for new anticancer/antimetastatic drugs. A multitude of studies has shown that CA IX inhibition decreases cancer cell proliferation and metastasis through pHe/pHi modulation and enhancement of ferroptosis among others. Numerous studies demonstrated increased efficacy of cytotoxic drugs combined with CA inhibitors (CAIs) in various cancer types. We tested the inhibitory effect of boric acid (BA), an inorganic Lewis acid, on CA IX as well as other isoforms (CA I, II, and XII). BA acted as a millimolar in vitro CAI, decreased proliferation of two cancer cell lines, although not strong correlations between the in vitro inhibition and in vivo effects were observed. The mechanism of antiproliferative action of BA should be investigated in more detail.

Systematic Review of Physical Activity, Sedentary Behaviour and Sleep Among Adults Living with Chronic Respiratory Disease in Low- and Middle-Income Countries.

Abstract: Physical activity (PA), sedentary behaviour (SB) and sleep are important lifestyle behaviours associated with chronic respiratory disease (CRD) morbidity and mortality. These behaviours need to be understood in low- and middle-income countries (LMIC) to develop appropriate interventions. Purpose: Where and how have free-living PA, SB and sleep data been collected for adults living with CRD in LMIC? What are the free-living PA, SB and sleep levels of adults living with CRD? Patients and Methods: The literature on free-living PA, SB and sleep of people living with CRD in LMIC was systematically reviewed in five relevant scientific databases. The review included empirical studies conducted in LMIC, reported in any language. Reviewers screened the articles and extracted data on prevalence, levels and measurement approach of PA, SB and sleep using a standardised form. Quality of reporting was assessed using bespoke criteria. Results: Of 89 articles, most were conducted in Brazil (n=43). PA was the commonest behaviour measured (n=66). Questionnaires (n=52) were more commonly used to measure physical behaviours than device-based (n=37) methods. International Physical Activity Questionnaire was the commonest for measuring PA/SB (n=11). For sleep, most studies used Pittsburgh Sleep Quality Index (n=18). The most common ways of reporting were steps per day (n=21), energy expenditure (n=21), sedentary time (n=16), standing time (n=13), sitting time (n=11), lying time (n=10) and overall sleep quality (n=32). Studies revealed low PA levels [steps per day (range 2669-7490steps/day)], sedentary lifestyles [sitting time (range 283-418min/day); standing time (range 139-270min/day); lying time (range 76-119min/day)] and poor sleep quality (range 33-100%) among adults with CRD in LMIC. Conclusion: Data support low PA levels, sedentary lifestyles and poor sleep among people in LMIC living with CRDs. More studies are needed in more diverse populations and would benefit from a harmonised approach to data collection for international comparisons.

Developing Appropriate Pulmonary Rehabilitation Services in Sri Lanka: Assessment of People Living with COPD and Healthcare Providers in Urban and Semi Urban Areas in Sri Lanka.

Introduction: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, corresponding to 5% of all deaths globally, with more than 90% occurring in low- and middle-income countries (LMIC). Pulmonary Rehabilitation (PR) is a routine clinical service for COPD management, often used in western countries. At present, there is no formal PR in Sri Lanka; a culturally appropriate programme is required that considers the views of adults living with COPD and healthcare providers (HCPs) who would be involved in the referral or delivery of PR. Purpose: The study assessed the attitudes and preferences of Sri Lankan adults living with COPD and attitudes and barriers of HCPs making PR referrals to inform an appropriate PR programme. Methodology: A descriptive cross-sectional study was conducted with the ethical clearance of Colombo south teaching hospital ERC committee (ERC Application No. 674), among adults living with COPD and HCPs in Colombo district, Sri Lanka. Adults living with COPD were enrolled August 2018-December 2018 using systematic random sampling from Colombo South Teaching Hospital and were assessed using a pre-tested interviewer administered questionnaire. HCPs were recruited from Colombo South Teaching Hospital and Jaffna Teaching Hospital between August 2018 and November 2018 and assessed using self-administered questionnaire. Results: Responses from 138 adults living with COPD (53% male, 52% aged ≥60 years) and 277 HCPs were collected. The majority of adults living with COPD were interested in participating in PR (80%) and would prefer PR to be delivered in a supervised, group-based, setting with hospital-based (49%). Adults living with COPD were mostly (73%) willing to spend between 30 minutes and 2 hours per day for PR-related activities. Among HCPs, 234 (83%) were nurses, 29 (11%) were hospital doctors and 14 (4%) were family physicians. The majority of HCPs stated that they were unsure about referring adults with COPD for PR (86%) and 61% stated considerable uncertainty regarding the availability of resources for PR. Nearly half of the HCPs (45%) felt they were not adequately prepared to refer adults living with COPD to PR programmes. Most HCPs (92%) reported that PR is worthwhile for COPD management. Conclusion: Adults living with COPD in Sri Lanka are willing to attend PR and would prefer group-based programmes delivered in hospitals, under the supervision of qualified personnel. Awareness about PR is poor and there is a lack of readiness to refer to PR amongst HCPs. There is an urgent need to train HCPs on PR and develop effective referral strategies to support PR uptake and delivery for adults living with COPD in Sri Lanka.

What should pulmonary rehabilitation look like for people living with post-tuberculosis lung disease in the Bishkek and Chui region of the Kyrgyz Republic? A qualitative exploration.

OBJECTIVE: After experiencing tuberculosis (TB), many people develop post-tuberculosis lung disease (PTBLD). Pulmonary rehabilitation (PR) centrally comprising of education and exercise is recommended internationally for people living with chronic respiratory diseases. However, no such service exists in Kyrgyzstan. This study investigated the opinions of healthcare professionals who would be expected to be potential future referrers to PR and adults living with PTBLD about what a PR programme could look like in Kyrgyzstan. DESIGN: A qualitative study using interviews and focus groups. Grounded theory and thematic analysis were used for data collection and analysis. PARTICIPANTS: 63 participants; 15 referrers (12 male, 3 female; 12 pulmonolgists, 3 TB specialists) and 48 adults (26 male, 22 female) living with PTBLD. SETTING: Participants were recruited from hospital settings in Bishkek and Chuy Region, Kygryzstan. METHODS: Fifteen semistructured interviews were conducted with referrers and nine focus group discussions were conducted with adults living with PTBLD. RESULTS: Five key themes were developed: (1) living with PTBLD; (2) attitude to PR, which emphasised the perceived importance and potential benefits of implemention; (3) barriers/facilitators to PR, which included time and cost, and the importance of appropriate communication in enabling participation; (4) interventional components of PR, which described culturally and demographically appropriate physical activities including rhythmic movements, dance and volleyball; and (5) psychosocial support, which demonstrated the importance of psychological support for patients coping with the effects of stigma. CONCLUSIONS: Potential referrers and adults living with PTBLD expressed their support for the implementation of PR. The culture-specific and population-specific issues highlighted in this work demonstrate the need to address stigma and provide certain types of exercise training/education modules for this specific clinical population. In other respects the currently known attitudes/barriers to PR, identified in Western research, appear to apply. The principles of culturally adapting PR may be helpful for those looking to establish similar clinical services in other low-income and middle-income countries and in Central Asia in particular.

Culturally adapted pulmonary rehabilitation for adults living with post-tuberculosis lung disease in Kyrgyzstan: protocol for a randomised controlled trial with blinded outcome measures.

INTRODUCTION: Pulmonary rehabilitation (PR) is a programme of individually prescribed physical exercise, education and self-management activities. PR is recommended in international guidelines for managing chronic obstructive pulmonary disease (COPD) and other chronic respiratory diseases. PR is still under-recognised in tuberculosis (TB) guidelines and PR is not available in many low and middle-income countries and for people with post-TB lung disease (PTBLD). The main aims of the study are to adapt and define a culturally appropriate PR programme in Kyrgyzstan for people living with PTBLD and to test, in a fully powered randomised controlled trial (RCT), the effectiveness of PR in improving exercise capacity for people living with PTBLD. METHODS AND ANALYSIS: The study will be divided into three stages: stage 1: focus group discussions with patients living with PTBLD and interviews with PR referrers will be conducted to explore initial perceptions and inform the cultural adaptation, structure and content of PR. Stage 2a: a single-blind RCT evaluating the effectiveness of a culturally adapted 6-week PR programme on maximal exercise capacity, assessed by the incremental shuttle walking test, before and after PR. Participants will be additionally followed-up 12 weeks postbaseline. Additional outcomes will include health-related quality of life, respiratory symptoms, psychological well-being and physical function. Stage 2b: participants' experience of PR will be collected through interviews and using a log book and a patient evaluation form. Staff delivering PR will be interviewed to explore their experience of delivering the intervention and refining the delivery for future implementation. ETHICS AND DISSEMINATION: The study was approved 22/07/2019 by Ethics Committee National Center for Cardiology and Internal Medicine (reference number 17) and by University of Leicester ethics committee (reference number 22293). Study results will be disseminated through appropriate peer-reviewed journals, national and international respiratory/physiotherapy conferences, social media, and through patient and public involvement events in Kyrgyzstan and in the UK. TRIAL REGISTRATION NUMBER: ISRCTN11122503.

Protocol for a single-centre mixed-method pre-post single-arm feasibility trial of a culturally appropriate 6-week pulmonary rehabilitation programme among adults with functionally limiting chronic respiratory diseases in Malawi.

INTRODUCTION: Malawi has a substantial burden of chronic respiratory diseases (CRDs) which cause significant morbidity and loss of economic productivity, affecting patients, families and health systems. Pulmonary rehabilitation (PR) is a highly recommended non-pharmacological intervention in the clinical management of people with CRDs. However, Malawi lacks published evidence on the implementation of PR for people with CRDs. This trial will test the feasibility and acceptability of implementing a culturally appropriate hospital-based PR programme among adults with functionally limiting CRDs at Queen Elizabeth Central Hospital in Blantyre, Malawi. METHODS AND ANALYSIS: This is a single-centre mixed-methods pre-post single-arm feasibility trial. Ten patients aged ≥18 years, with a spirometry confirmed diagnosis of a CRD and breathlessness of ≥2 on the modified Medical Research Council dyspnoea scale, will be consecutively recruited. Their baseline lung function, exercise tolerance and health status will be assessed; including spirometry, Incremental Shuttle Walk Test and Chronic Obstructive Pulmonary Disease Assessment Test, respectively. Pretrial semistructured in-depth interviews will explore their experiences of living with CRD and potential enablers and barriers to their PR uptake. Along with international PR guidelines, these data will inform culturally appropriate delivery of PR. We initially propose a 6-week, twice-weekly, supervised centre-based PR programme, with an additional weekly home-based non-supervised session. Using combination of researcher observation, interaction with the participants, field notes and informal interviews with the participants, we will assess the feasibility of running the programme in the following areas: participants' recruitment, retention, engagement and protocol adherence. Following programme completion (after 6 weeks), repeat assessments of lung function, exercise tolerance and health status will be conducted. Quantitative changes in clinical outcomes will be described in relation to published minimal clinically important differences. Post-trial semistructured interviews will capture participants' perceived impact of the PR programme on their quality of life, enablers, and barriers to fully engaging with the programme, and allow iteration of its design. ETHICS AND DISSEMINATION: Ethical approval for this trial was obtained from University of Malawi College of Medicine Research and Ethics Committee (COMREC), Blantyre, Malawi (protocol number: P.07/19/2752) and University of Leicester Research Ethics Committee, Leicester, UK (ethics reference: 31574). The results of the trial will be disseminated through oral presentations at local and international scientific conferences or seminars and publication in a peer-reviewed journal. We will also engage the participants who complete the PR trial and the Science Communication Department at Malawi-Liverpool-Wellcome Trust Clinical Research Programme to organise community outreach activities within Blantyre to educate communities about CRDs and PR. We will also broadcast our trial results through national radio station programmes such as the weekly "Thanzi la Onse" (Health of All) programme by Times Radio Malawi. We will formally present our trial results to Blantyre District Health Office and Malawi Ministry of Health. TRIAL REGISTRATION NUMBER: ISRCTN13836793.

Identifying Appropriate Delivery of and Referral to Pulmonary Rehabilitation in Uganda: A Survey Study of People Living with Chronic Respiratory Disease and Health Care Workers.

Introduction: Pulmonary rehabilitation (PR) is a low cost, high impact intervention that ameliorates the disability associated with chronic respiratory diseases (CRD). PR is becoming increasingly recognized in low resource settings where the burden of CRD is rapidly increasing. To aid the implementation of PR in Uganda, we conducted a study to assess the attitudes and opinions towards PR among patients with CRD in Uganda and explore barriers faced by health care workers (HCWs) in referring to PR. Methods: A cross-sectional study comprising two survey populations: people living with CRD and HCWs regarded as potential PR referrers and PR deliverers. This exploratory study sought initial opinions and thoughts regarding PR, as well as baseline knowledge and potential barriers faced in the referral process. Results: Overall, 30 HCWs (53% female, 43% doctors) and 51 adults with CRD (63% female) participated in the survey. Among those with CRD, the majority reported breathlessness as a major problem (86%) and breathlessness affected their ability to do paid and unpaid work (70%). Interest in PR was high amongst adults with CRD (92%) with preference for a hospital-based programme (67%) as opposed to community-based (16%) or home-based (17%). All HCWs considered PR important in lung disease management, but 77% do not refer patients due to a lack of information about PR. HCWs' free-text responses identified the need for training in PR, patient education and streamlining the referral process as key elements to develop successful PR referral services. Conclusion: To successfully set up a PR service for people with CRD in Uganda, there is a great need for appropriately tailored training and education of prospective referrers about CRD and PR programs. Educating patients about the benefits of PR as well as streamlining the referral process is critical in expanding PR services across Uganda to fulfill this unmet need.

Protocol for the cultural adaptation of pulmonary rehabilitation and subsequent testing in a randomised controlled feasibility trial for adults with chronic obstructive pulmonary disease in Sri Lanka.

INTRODUCTION: International guidelines recommend pulmonary rehabilitation (PR) should be offered to adults living with chronic obstructive pulmonary disease (COPD), but PR availability is limited in Sri Lanka. Culturally appropriate PR needs to be designed and implemented in Sri Lanka. The study aims to adapt PR to the Sri Lankan context and determine the feasibility of conducting a future trial of the adapted PR in Sri Lanka. METHODS AND ANALYSIS: Eligible participants will be identified and will be invited to take part in the randomised controlled feasibility trial, which will be conducted in Central Chest Clinic, Colombo, Sri Lanka. A total of 50 participants will be recruited (anticipated from April 2021) to the trial and randomised (1:1) into one of two groups; control group receiving usual care or the intervention group receiving adapted PR. The trial intervention is a Sri Lankan-specific PR programme, which will consist of 12 sessions of exercise and health education, delivered over 6 weeks. Focus groups with adults living with COPD, caregivers and nurses and in-depth interviews with doctors and physiotherapist will be conducted to inform the Sri Lankan specific PR adaptations. After completion of PR, routine measures in both groups will be assessed by a blinded assessor. The primary outcome measure is feasibility, including assessing eligibility, uptake and completion. Qualitative evaluation of the trial using focus groups with participants and in-depth interviews with PR deliverers will be conducted to further determine feasibility and acceptability of PR, as well as the ability to run a larger future trial. ETHICS AND DISSEMINATION: Ethical approval was obtained from the ethics review committee of Faculty of Medical Sciences, University of Sri Jayewardenepura, Sri Lanka and University of Leicester, UK. The results of the trial will be disseminated through patient and public involvement events, local and international conference proceedings, and peer-reviewed journals. TRIAL REGISTRATION NUMBER: ISRCTN13367735.
