Abstract
Background and Objective: Sickle Cell Disease (SCD) is known to cause acute severe pain episodes known as vaso-occlusive crisis (VOC) mainly treated with opioid analgesics. Since the opioid epidemic there is an interest in determining the opioid misuse potential in these patients. Therefore, the primary objective of this study is to determine the rates of opioid misuse among patients with SCD by assessing the rate of unexpected drug screening results in a sickle cell disease clinic. Methods: This was a retrospective chart review study conducted at the outpatient sickle cell disease clinic. The primary independent variables were the prescribed opioid medications while the primary dependent variable was the collected opioid metabolite. Descriptive statistics, linear regression and multivariate logistic regression analysis were conducted using SPSS version 24. Results: A total of 100 participants were recruited from July 1, 2018, to June 30, 2020 with 71 included in the analysis. The total mean of morphine milligram equivalents (MME) for all participants was 71.1±104.9 with 71% of participants having a daily calculated MME of <90MME. The odds of misusing an opioid were 6.72 times higher (P<.02) if a participant used marijuana compared to a participant who didn't. In addition, the odds of misusing an opioid were 2.47 times higher (P<.04) if the patient was prescribed an opioid daily dose greater than 90 MME as opposed to a daily dose less than 90 MME. Conclusion: Participants who consumed greater than 90 MME's per day and utilized marijuana were more likely to misuse opioids.

Colorectal cancer: Genetic alterations, novel biomarkers, current therapeutic strategies and clinical trials. Gene 2024; 892:147857. [PMID: 37783294 DOI: 10.1016/j.gene.2023.147857] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 09/22/2023] [Accepted: 09/28/2023] [Indexed: 10/04/2023]
Abstract
Colorectal cancer (CRC) is the third most commonly detected cancer with a serious global health issue. The rates for incidence and mortality for CRC are alarming, especially since the prognosis is abysmal when the CRC is diagnosed at an advanced or metastatic stage. Both type of (modifiable/ non-modifiable) types of risk factors are established for CRC. Despite the advances in recent technology and sophisticated research, the survival rate is still meager due to delays in diagnosis. Therefore, there is urgently required to identify critical biomarkers aiming at early diagnosis and improving effective therapeutic strategies. Additionally, a complete understanding of the dysregulated pathways like PI3K/Akt, Notch, and Wnt associated with CRC progression and metastasis is very beneficial in designing a therapeutic regimen. This review article focused on the dysregulated signaling pathways, genetics and epigenetics alterations, and crucial biomarkers of CRC. This review also provided the list of clinical trials targeting signaling cascades and therapies involving small molecules. This review discusses up-to-date information on novel diagnostic and therapeutic strategies alongside specific clinical trials.

Abstract
People living with HIV (PLWH) are at higher risk of reactivation of Chagas disease, a neglected tropical disease, caused by Trypanosoma cruzi. There are no data from UK HIV clinics on the prevalence of T. cruzi. We implemented T. cruzi screening at our clinic as part of routine care for PLWH with epidemiological risk factors. Among 86 patients screened, none had positive serology: one seropositive patient was identified due to increased clinician awareness. Implementing T. cruzi screening as part of routine clinical care was feasible, though labour intensive and identified at-risk individuals.

Lessons Learned From the Implementation of a School-Based Sexual Health Education Program for Adolescent Girls in Cape Town, South Africa. GLOBAL HEALTH, SCIENCE AND PRACTICE 2023; 11:e2300026. [PMID: 38124019 PMCID: PMC10749656 DOI: 10.9745/ghsp-d-23-00026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 10/31/2023] [Indexed: 12/23/2023]
Abstract
Comprehensive sexual education (CSE) is an important approach for health promotion dissemination in schools, particularly when delivered in participatory ways that are sport based, peer or near-peer led, and include concepts of gender and power dynamics. Sufficient attendance at CSE sessions is critical to ensure content exposure and build potential for impact. This article details implementation lessons from the delivery of an after-school, near-peer-led CSE program called SKILLZ during a cluster randomized controlled trial among 40 secondary schools in Cape Town, South Africa. SKILLZ is an evidence-based program previously implemented in similar contexts. Attendance in this study was suboptimal (less than 50%) despite qualitative indications of high acceptability and extensive efforts to adapt implementation and boost attendance. Qualitative and quantitative data gathered during anonymous surveys, in-depth interviews, and focus group discussions with participants with high and low attendance records, near-peer coaches, and school staff from both cohorts indicated that poor attendance could be attributed to several factors. Program adaptations, such as delivering difficult-to-access health services before participants attended the SKILLZ program rather than after, may have reduced the incentive for young people to attend the program. Practical barriers to attendance were identified, including security concerns, competing priorities, and unfamiliarity with after-school programming culture in this setting. Community engagement and acceptability of sexual education programs for adolescents alone may be insufficient to ensure program uptake and engagement.

Retrospective analysis of the biopharmaceutics characteristics of solid oral Modified-Release drug products in approved US FDA NDAs designated as Extended-Release or Delayed-Release formulations. Eur J Pharm Biopharm 2023; 193:294-305. [PMID: 37984592 DOI: 10.1016/j.ejpb.2023.11.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 11/15/2023] [Accepted: 11/17/2023] [Indexed: 11/22/2023]
Abstract
BACKGROUND Modified Release (MR) orally administered drugs products [Extended-Release (ER) and Delayed-Release (DR)] differ from Immediate-Release (IR) drug products in their drug release site and/or rate to offer therapeutic advantages. It is important to understand the biopharmaceutics factors that determine how a drug works in the gastrointestinal tract and the various pharmacokinetic properties that determine a drug's rate of absorption and release in the human body. To better understand the biopharmaceutics characteristics of ER and DR drug products, this study retrospectively analyzed submissions approved by the US Food and Drug Administration (FDA), from 2001 to 2021, and their corresponding review documents. This review work is expected to enhance the readers' understanding regarding the biopharmaceutics properties that supported approval of these products' ER claims, as per 21 CFR 320.25(f), and DR claims. METHODS A comprehensive search was conducted using the FDA's internal New Drug Application (NDA) database for ER and DR oral drug products approved between 2001 and 2021. The search yielded 87 ER applications (23 ER capsules and 64 ER tablets) and 21 DR applications (10 DR capsules, 11 DR tablets) for which electronic records were accessible. These products were analyzed for overall drug product design, dosing frequency compared to the reference (if applicable), degree of fluctuation, dissolution method, and alcohol dose-dumping. RESULTS Out of 87 total applications for ER drug products that were assessed, 62% of the ER tablets contained a polymer matrix formulation, and hypromellose (HPMC) was used in 50% of these products. 52% of the ER capsules consisted of polymer beads while about half of the DR drug products contained a non-bead formulation with a combination of polymers. The majority of ER drug products were found to have a reduction in dosing frequency and a decrease in the degree of fluctuation when compared to the IR reference product. The 13 ER drug products that exhibited an increase in degree of fluctuation exhibited general and pharmacodynamic benefits, such as reduced dosing frequency and reduced pill burden. The majority of DR formulations were developed to prevent drug degradation in the stomach, followed by to decrease potential stomach irritation, and lastly for localized release in the colon. The majority of ER drug products had 1:1 ratios of dissolution duration compared to dosing frequency (i.e., the majority of ER drug products had a dissolution duration of 24 h and were dosed every 24 h while those with a dissolution duration of 12 h were dosed every 12 h). The majority of ER applications had single-stage dissolution methods while most DR drug products used biphasic dissolution methods. All of the DR dissolution methods incorporated an acid stage of 2 h and a buffer stage with various timeframes. 53% the DR drug products had a ratio of dissolution duration to dosing frequency of 1:4 (e.g. a dissolution duration of 2 h to a dosing frequency of 8 h) or 1:8 (e.g. a dissolution duration of 2 h to a dosing frequency of 16 h). Of the ER tablets and DR drug products, 72% exhibited no alcohol dose-dumping under in vitro testing conditions. ER capsules, however, did not yield similar results-most of which exhibited alcohol induced dose-dumping. Alcohol dose dumping was mitigated by either in vivo studies or warnings on the drug product label. CONCLUSION The results of this study help the reader understand the design, characteristics, and pharmacological advantages of the ER and DR drug products for patient benefit; as well as the regulations governing the FDA's assessment of ER claims.

Abstract
Limited information is available regarding the efficacy of antiretrovirals in people with HIV-1 and high or very high Body Mass Index (BMI). This is especially the case for the alafenamide salt of tenofovir as clinical trials have only enrolled patients with BMI ≤30 kg/m2. Lower concentrations of some antiretrovirals are expected in patients with BMI >30 kg/m2 due to potential changes in clearance and distribution of medication. This report describes an individual taking tenofovir alafenamide, emtricitabine and efavirenz in whom HIV-1 viral load was consistently undetectable (<50 copies/ml) over a 2.5 year period. During this period the patient's BMI ranged between 59.8 and 68.1 kg/m2. Further data is required to support the efficacy of antiretrovirals in individuals with high and very high BMI.

School-based healthcare services in Cape Town, South Africa: When there's a will, there's a way. Afr J Prim Health Care Fam Med 2023; 15:e1-e3. [PMID: 37916715 PMCID: PMC10623473 DOI: 10.4102/phcfm.v15i1.4216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 08/30/2023] [Accepted: 09/07/2023] [Indexed: 11/03/2023] Open
Abstract
South African secondary schools do not deliver school-based healthcare services despite high rates of human immunodeficiency virus (HIV) infection, sexually transmitted infections, and unplanned pregnancies among adolescents, ongoing sub-optimal uptake of healthcare services from public healthcare facilities by adolescents, and national policy support for such services. A pilot school health nursing programme (SHNP) was offered to 44 secondary schools in a single health sub-district within the Western Cape, South Africa. The programme included fortnightly nurse visits that offered a standard package of healthcare services, including sexual and reproductive health services tailored according to school preference.Of the 44 schools, 42 gave permission for the SHNP to operate, with the majority of schools selecting the full comprehensive package of services. Programme implementation was truncated such that delivery only occurred over two school terms (20 weeks); however, 344 students attended the service. The majority of service users were female with a median age of 16 years, and over a half attended the service for sexual and reproductive health services.Contribution: A key challenge to school-based health service delivery arose from inadequate stakeholder support and differential views of adolescent healthcare needs among government officials, parents, guardians, school staff and governing bodies. These findings motivate for ongoing multi-level stakeholder engagement around the reality of adolescent healthcare needs and further opportunities to deliver school health services for longer time periods such that their feasibility, acceptability, and potential to impact healthcare outcomes can be assessed in this setting.

Acceptability, feasibility and cost of point of care testing for sexually transmitted infections among South African adolescents where syndromic management is standard of care. BMC Health Serv Res 2023; 23:1078. [PMID: 37817160 PMCID: PMC10566254 DOI: 10.1186/s12913-023-10068-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 09/25/2023] [Indexed: 10/12/2023] Open
Abstract
BACKGROUND Young people (YP) in southern Africa are at substantial risk of HIV and sexually transmitted infections (STIs). Despite the epidemiological and biological link between STIs and HIV transmission and acquisition, infections such as Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) remain widely undiagnosed. Syndromic STI management is the standard of care in low- and middle-income countries (LMICs) despite a high prevalence of asymptomatic infections. We conducted an observational study to explore the acceptability, feasibility, and cost of a STI test-and-treat service for YP in Cape Town. METHODS YP attending a mobile clinic (MC) and a youth centre clinic (YC) were offered STI screening. Urine testing for CT and NG using a 90-min molecular point-of-care (POC) test on the GeneXpert platform was conducted and treatment provided. Data were collated on demographics, sexual behaviour, presence of symptoms, uptake of same-day treatment, prevalence of CT/NG, and service acceptability. RESULTS Three hundred sixty six participants were enrolled (median age 20, 83% female).57% (209/366) of participants tested positive for either CT (126/366, 34%) or NG (57/366, 16%) or co-infection (26/366, 7%). Clinical symptoms were a poor predictor of GeneXpert diagnosed CT or NG, with a sensitivity of 46.8% and 54.0% for CT and NG respectively. Although half of participants initially chose to receive same day results and treatment, only a third waited for results on the day. The majority of participants (91%) rated the service highly via a post-visit acceptability questionnaire. CONCLUSION Curable STIs are highly prevalent in this population. STI screening using POC testing was feasible and acceptability was high. The study provides further impetus for moving policy beyond syndromic management of STIs in South Africa.

Abstract
BACKGROUND HIV remains a leading contributor to the disease burden in sub-Saharan Africa, with adolescents and young people disproportionately affected. Optimising pre-exposure prophylaxis (PrEP) uptake has predominantly focused on women and adult men who have sex with men. We explore adolescent boys and young men's PrEP uptake preferences in South Africa, Uganda, and Zimbabwe. METHODS A cross-sectional sequential exploratory mixed-methods study amongst males aged 13-24 years was conducted between April and September 2019 as part of the CHAPS trial. Group discussions (GDs) and In-Depth Interviews (IDIs) focused on motivations and hindrances for HIV testing, PrEP preference, and reasons for the uptake of PrEP. A thematic approach was used to analyse the qualitative data. A quantitative survey following the qualitative work covered questions on demographics, HIV risk and PrEP preferences (on-demand vs. daily). For quantitative analysis, we fitted logistic regression models to determine factors associated with on-demand vs daily PrEP preference. RESULTS Overall, 647 adolescent boys and young men (median age 20, IQR: 17-22) were enrolled. Of these, 422 (65.22%) preferred on-demand PrEP (South Africa 45.45%, Uganda 76.80%, Zimbabwe 70.35%; p<0.001). Factors independently associated with on-demand PrEP included country (South Africa, adjusted odds ratio (aOR) = 0.19 [95%CI:0.1-0.3] compared to Uganda) and advanced planning of sex [>24 hours in advance aOR = 1.4 (0.9-2.3) compared to <2 hours]. Qualitatively, participants commonly believed they were not at risk of HIV acquisition most of the time and thought that on-demand PrEP would be suitable as they tend to plan sexual activity in advance. CONCLUSION Preference for on-demand PrEP is high in young males. The qualitative data support a preference for on-demand PrEP in those who plan sex in advance. HIV intervention programs should offer both on-demand and daily PrEP to engage more adolescent boys and young men in HIV prevention practices.

Abstract
PURPOSE/OBJECTIVE(S) Conventionally fractionated radiotherapy (RT) has shown to have excellent local control in hematological malignancies (HM). Up to date there is none or scant literature about the use of hypofractionated radiotherapy (HFRT) for the treatment of HM, this single institution study analyzed the efficacy of HFRT in HM. We hypothesized that HFRT in HM will result in a similar local tumor control that has been reported with standard fractionated RT. MATERIALS/METHODS In this retrospective study, we analyzed the data from patients within the provincial cancer registry diagnosed with HM treated with a curative intent using HFRT regimens suggested by International Lymphoma Radiation Oncology Group between 2020-2022 during the COVID-19 pandemic. Primary outcome of the study was overall response rate (ORR), measured as complete response (CR), partial response (PR) or stable disease (SD) within the irradiated field determined radiologically or clinically post completion of RT. Secondary end point was freedom from local progression (FFLP), calculated from the date of initiation of RT to the first date among in-field progression, death, and last follow-up. Summary statistics were used to describe cohort and treatment characteristics. FFLP was calculated by 1 minus cumulative incidence accounting for competing risk (i.e., death). RESULTS Of the 36 patients included for analysis, 18 were aggressive non-Hodgkin lymphoma (NHL), 9 were indolent NHL, 6 were Hodgkin lymphoma (HL) and 3 were other HM. Among them 25 had consolidation RT and 11 had definitive RT. HFRT daily dose per fraction ranged from 2.67 Gy to 5 Gy and total dose regimens ranged from 18 Gy to 42.5 Gy in 6 - 17 fractions and median equivalent dose in 2 Gy fractions (EQD2) for alpha/beta = 10Gy was 36 Gy (±7.5). ORR for the entire cohort was 94.4%. With a median follow up of 13.2 months, FFLP at one year for the entire cohort was 91.5% and death without infield progression was 8.7%. Among the 4 patients who had in radiation field recurrence, 2 had aggressive NHL and 2 had HL. No grade 3 or 4 acute toxicities were reported. CONCLUSION This retrospective study using HFRT showed an ORR and FFLP comparable to historical studies using standard fractionation. Further long-term follow-up is warranted to confirm these findings.

Abstract
PURPOSE/OBJECTIVE(S) Hypofractionated and stereotactic body radiotherapy (SBRT) are increasingly used in the treatment of centrally located, early-stage non-small cell lung cancer (NSCLC), though there are concerns of increased morbidity and mortality in patients with ultracentral tumors (UC). We report on the long-term toxicity of patients with UC lung cancer treated on a prospective randomized clinical trial of SBRT versus conventionally hypofractionated radiotherapy (CRT) for stage I NSCLC (NCT01968941). MATERIALS/METHODS Patients with UC tumors, defined as those where the planning target volume directly overlaps with the proximal bronchial tree (PBT), were identified from the larger cohort of patients treated on the trial. These patients received either SBRT with 60 Gy in 8 fractions or CRT with 60 Gy in 15 fractions. The primary endpoint of this secondary analysis was development of any grade 3 or higher toxicity defined using CTCAE version 3.0. Secondary endpoints included local control, as well as dosimetric analysis of the PBT, using EQD2 with α/β ratio of 3 to assess the relationship between dose to the PBT and toxicity. RESULTS Twenty-nine patients were identified with UC tumors; 21 received SBRT and 8 received CRT. Median age was 72 years (range 55-88 years) and 59% were female. Median FEV1 was 1.46L (range 0.64-2.37L). Patients had either T1 (59%) or T2 (41%) lesions, with median tumor size 2.5cm (range 1.1-4.9cm). Most patients had histologically confirmed disease (squamous cell, n = 10; adenocarcinoma, n = 8; radiographically suspicious, n = 11). The median follow-up was 2.9 years (range 0.7-5.2 years). The 3-year local control rate of all patients was 88.3% (95% confidence interval: 75.7-100%). There were 3 patients with late (>3 months) grade 3 toxicity (bronchial stricture, chest pain, and atelectasis) and 1 patient with late grade 5 toxicity (bleeding/hemorrhage), all treated in the SBRT arm. Median EQD2 dose to PBT in patients with grade ≥3 late toxicity compared to the rest of the cohort was: Dmax, 132 vs 129 Gy; D0.1cc, 129 vs 119 Gy; D1cc, 124 vs 80 Gy; and D5cc, 83 vs 41 Gy. Median EQD2 volumetric doses in grade ≥3 patients (compared to the rest) to PBT were: V65 Gy, 9.7 vs 2.2cc; V80 Gy, 7.9 vs 1.1cc; V90 Gy, 6.2 vs 0.4cc; and V100 Gy, 4.8 vs 0.3cc. The single patient with grade 5 toxicity had the highest D5cc (116 Gy) and V100 Gy (7cc) among all patients. CONCLUSION Stereotactic radiation with 60 Gy in 8 fractions for UC lung cancer provides good local control but carries an approximately 15-20% rate of late grade ≥3 toxicity. There appears to be a dosimetric association between toxicity and dose to the PBT. It may be more important to minimize volumetric PBT dose rather than maximum point dose to reduce risk of severe late toxicity.

Goals for girls: a cluster-randomized trial to investigate a school-based sexual health programme amongst female learners in South Africa. HEALTH EDUCATION RESEARCH 2023; 38:375-391.

Abstract
The delivery of comprehensive sexuality education to adolescents at school is recognized as a long-term strategy to support adolescent health. Suboptimal sexual and reproductive health (SRH) outcomes among South African adolescents necessitate the ongoing development and optimization of SRH education and promotion models. We conducted a cluster-randomized controlled trial amongst secondary schools (n = 38) in Cape Town, South Africa, to evaluate a sport-based, near-peer-led SRH curriculum, SKILLZ, amongst female learners (n = 2791). Biomedical (sexually transmitted infections [STIs], human immunodeficiency virus [HIV] and pregnancy) and socio-behavioural (social support, gender norms and self-concept) outcomes were assessed pre and post intervention. Attendance at SKILLZ was low and intervention participants did not show an improvement in SRH outcomes, with HIV and pregnancy incidence remaining stable and STI prevalence remaining high and increasing in both control and intervention arms. Although evidence of positive socio-behavioural measures was present at baseline, participants with high attendance showed further improvement in positive gender norms. SKILLZ did not demonstrate the capacity to significantly impact clinical SRH outcomes. Modest improvements in outcomes amongst high attenders suggest that the impact may be possible with improved attendance; however, in the absence of optimal attendance, alternative intervention strategies may be required to improve SRH outcomes amongst adolescents.

Abstract
Despite recent advances in neonatal care, early detection of neonatal sepsis still remains challenging. Positive blood culture is the gold standard for definitive diagnosis of neonatal sepsis but is time consuming and demands a well equipped laboratory setting. Therefore, it becomes imperative to evaluate usefulness of white blood cell count, Immature to total (IT) ratio and C-reactive protein as potential markers in the early diagnosis of neonatal sepsis. The objective of the study was to evaluate role of white blood cell count, IT ratio and C-reactive protein in early detection of clinically suspected neonatal sepsis. This cross-sectional descriptive study was conducted from January 2017 to December 2018 at Special Care Newborn Unit (SCANU) of Rangpur Medical College Hospital, Rangpur, Bangladesh. After parental permission and ethical clearance, a total of 70 eligible neonates were included into the study. Estimation of total white blood cell count, IT ratio and C-reactive protein as well as blood culture were done for each case. Significance for Chi-Square test and Pearson's correlation coefficient test was predetermined as p<0.05. Of the total 70 neonates studied, 19(27.14%) were blood culture positive and most common organism was Escherichia coli (7/14, 37.0%). Among individual and combination tests, CRP was highly sensitive (100%) followed by WBC count (74.94%). Highly specific tests in diagnosing sepsis were combination test of IT ratio and CRP (88.23%) followed by combination test of WBC count and CRP (82.35%). Positive predictive value (PPV) was high for combination test of WBC count and CRP (90.90%) followed by combination test of IT ratio and CRP (90.47%). Negative predictive value (NPV) was high in CRP (100.0%) followed by WBC count (89.19%). IT ratio positively correlated with CRP (p=0.002) and there was significant association between raised CRP and WBC count (p=0.005) in neonatal sepsis. Diagnostic role of both individual and combination tests were significant in early detection of clinically suspected neonatal sepsis while awaiting results of blood culture. However, none of the combination tests were able to achieve 100.0% sensitivity.

A qualitative study to explore daily versus on-demand oral pre-exposure prophylaxis (PrEP) in young people from South Africa, Uganda and Zimbabwe. PLoS One 2023; 18:e0287627. [PMID: 37384792 PMCID: PMC10310032 DOI: 10.1371/journal.pone.0287627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Accepted: 06/12/2023] [Indexed: 07/01/2023] Open
Abstract
BACKGROUND Adolescents in sub-Saharan Africa (SSA) remain vulnerable to HIV infection. While pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV transmission as a daily or on-demand regimen, tailored approaches are necessary. The Combined HIV Adolescent PrEP and Prevention Study (CHAPS) is a mixed-methods research program investigating the acceptability and feasibility of implementing daily and on-demand PrEP among young people in SSA. It also aims to determine an on-demand dosing schedule for insertive sex. For this paper, we explored preferences for daily versus on-demand PrEP amongst adolescents as part of CHAPS. METHODS Purposive sampling was used to recruit participants from Soweto and Cape Town (South Africa), Wakiso district (Uganda) and Chitungwiza (Zimbabwe). At the time of the study in 2018/2019, Uganda had not rolled out PrEP to the general population; in Zimbabwe, PrEP for young people was only available at selected sites with one located within the study recruitment area. In South Africa, PrEP was made available to selected high-risk groups. We conducted 60 in-depth interviews and 24 group discussions amongst young people aged 13-24 without HIV in South Africa, Uganda, and Zimbabwe. All in-depth interviews and group discussions were audio-recorded, transcribed verbatim and translated to English. Data were analysed using framework analysis. The main themes were centered around preferences for daily and on-demand PrEP. RESULTS Reasons for on-demand preferences included stigma, pill fatigue, adherence and side effects. Reasons for daily PrEP preferences included factors related to sexual risk behaviour, continuous protection against incidents of unintentional exposure, and the increased efficacy of a daily dose. Participants at all sites preferring daily PrEP identified the same reasons, with more males than females citing inadvertent blood contact or perceived increased efficacy. Similarly, participants at all sites preferring on-demand PrEP gave the same reasons for their preferences for on-demand PrEP; the exception was South Africans who did not mention the hope of having fewer side effects by not taking daily PrEP. Additionally, more males than females cited intermittent sex as a reason for opting for on-demand PrEP. CONCLUSIONS Our study is the first known to explore and describe youth preferences for daily versus on-demand PrEP. While the choice is clear-cut, the reasons cited in the different options provide invaluable insights into their decisions, and the actual and perceived facilitators and barriers to access to PrEP. Further education is needed amongst young people, not only about PrEP but also in other areas of comprehensive sexuality education. Exploring all options of HIV prevention is crucial to provide a tailored, one-size-does-not-fit-all approach to adolescent care in SSA to reduce and, the continued and increasing risk of this preventable infection.

Abstract
OBJECTIVE Statins' efficacy and safety are subject to wide inter-individual variability, partly due to genetic predisposition. Studies have shown that the genetic variations in the common solute carrier organic anion transporter family member 1B1 (SLCO1B1) gene polymorphisms affect the transport of statins' transport into hepatocytes, their plasma concentration, and circulation time. The ultimate result is variable and personalized statins response and statin-associated muscular symptoms (SAMS). Here we report an update on the differential response to rosuvastatin therapy in the Pakistani population. PATIENTS AND METHODS A total of 166 hyperlipidemic patients on rosuvastatin were prospectively followed for 24 weeks. Muscle symptoms were recorded after 6-8 weeks of therapy, and assessment was done according to the SAMS-clinical index tool. Patients were genotyped for SLCO1B1 c.521T>C and c.388A>G polymorphisms, for association with lipid-lowering response and statin-associated muscle symptoms. The plasma level of rosuvastatin was determined through Liquid chromatography-mass spectrometry (LCMS) for possible correlation with adverse effects and lipid-lowering efficacy. RESULTS Mean reduction in low-density lipoprotein cholesterol (LDL-C) was 42.34 mg/dl (p<0.001), 35.66 mg/dl (p<0.001), and 24.47 mg/dl (p=0.202) in reference, heterozygous and mutant homozygous groups of SLCO1B1 c.521T>C, respectively. A 15.70% and 42.14% diminished LDL-C reduction was observed in c.521TC and c.521CC, respectively, compared to the reference c.521TT genotype. Similarly, for SLCO1B1 c.388A>G, 20.50% and 29.40% less LDL-C lowering effect was observed in heterozygous and mutant homozygous carriers, respectively. SAMS were observed in 37% and 33% of heterozygous and minor homozygous, respectively, (p=0.059). The rosuvastatin plasma level was 1.89-fold higher in the c.521CC genotype than in the reference homozygous type. CONCLUSIONS Differential lipid-lowering response and muscular symptoms due to rosuvastatin are associated with the SLCO1B1 common polymorphisms. Further studies are needed to validate dose adjustment and rationalization.

Abstract
OBJECTIVE Conventional use of retraction cord in soft tissue management is effective only when the non-resilient nature of material does not jeopardize gingival health. Therefore this study aims to clinically evaluate the gingival displacement, ease of application and bleeding from polytetrafluoroethylene (PTFE) retraction cord. PATIENTS AND METHODS This study is a single-center, parallel-group, randomized controlled clinical trial (1:1). Sixty patients indicated for full coverage metal-ceramic restoration for first molars were enrolled and randomly allocated to experimental (PTFE Cord) and control (conventional plain retraction cord) groups. After crown preparation and isolation, a pre-displacement impression was made. Assigned gingival displacement material was applied for 5 minutes, followed by post-displacement impression. Casts were prepared and used for assessment of mean horizontal gingival displacement by measuring displacement using a stereomicroscope (20 x). Post-displacement gingival bleeding and ease of application were also assessed clinically. t-test and Chi-square tests were used for statistical assessment of gingival displacement, gingival bleeding and ease of application. RESULTS Gingival displacement, bleeding and ease of application were similar among study groups (p > 0.05). Mean gingival displacement in the experimental group was 197.1 µm, and 167.7 µm in the control group. Bleeding was observed in 30% and 20% of cases of experimental and control group, respectively. Ease of application was 'difficult' in 53.3% and 43.3% of cases of experimental and control group, respectively. Non-impregnated gingival retraction cord and PTFE cord displayed similar outcomes of gingival displacement, ease of placement and bleeding after cord removal. CONCLUSIONS Post-displacement bleeding and discomfort for PTFE cord placement suggest that this technique needs improvement. Therefore further studies are warranted to improve and investigate the physical and biological response to PTFE retraction cord.

Abstract
SUMMARY South Africa has a high burden of trauma related injuries with haemorrhage remaining a leading treatable complication of trauma. Expedient management of haemorrhage serves to reduce patient morbidity and mortality. Damage control surgery aims to minimise haemorrhage, contain contamination, and allow restoration of physiology in an intensive care unit (ICU) before proceeding to definitive surgery. Over time, damage control surgery has found favour in non-traumarelated surgeries in unstable patients. The Jehovah's Witness (JW) religion believes that blood is sacred and strictly do not consent to blood or blood product transfusions, including in emergency settings. Thus, the management of a bleeding or bled-out JW patient proves to be a unique challenge in modern medicine. For the JW patient who is undergoing damage control surgery, the primary goal is to win time for recovery of the haemoglobin level by maintaining adequate oxygen delivery to tissues. We review the multiple methods available to optimise haemodynamic stability in a bleeding JW patient. These include techniques aimed at (i) minimising blood loss, (ii) optimising oxygen delivery (DO2), (iii) optimising oxygen consumption (VO2), and (iv) correction of coagulopathy. The management of haemorrhage in the JW patient remains challenging. It is imperative for healthcare professionals to be aware of all options available when treating these patients in order to provide optimal treatment whilst maintaining respect for their beliefs.

Abstract
The poor physical health (including oral health) of people with mental disorders is a global problem. The burden of oral diseases among this group is substantial given their high prevalence and ability to increase the personal, social, and economic impacts of mental disorders. This article summarizes causes of mental disorders and oral diseases, critically reviews current evidence on interventions to reduce the burden of oral diseases in people with mental disorders, and suggests future research directions. The relationship between mental disorders and oral diseases is complex due to the shared social determinants and bidirectional interaction mechanisms that involve interconnected social, psychological, behavioral, and biological processes. Research has, to date, failed to produce effective and scalable interventions to tackle the burden of oral diseases among people with mental disorders. Transformative research and actions informed by a dynamic involvement of biological, behavioral, and social sciences are needed to understand and tackle the complex relationship between mental disorders and oral diseases, as well as inform the design of complex interventions. Examples of future research on complex public health, health service, and social care interventions are provided. The design and testing of these interventions should be carried out in real-world settings, underpinned by the principles of coproduction and systems thinking, and conducted by a transdisciplinary team. We propose this starts with setting research priorities and developing complex intervention theory, which we report to support future research to improve oral health and hence physical and mental health in this disadvantaged group.

Abstract
Purpose/Objective(s) In response to the COVID-19 pandemic, a single fraction peripheral lung SBRT program was established to minimize potential COVID-19 exposures. This analysis aims to review clinical and treatment characteristics and associated toxicities in appropriately selected patients for this newly implemented technique. Materials/Methods From May 2020 until Feb 2022, patients with peripheral lung tumors who met eligibility for 3400cGy in a single-fraction SBRT were treated at a tertiary academic cancer center. Patient, treatment, and toxicity parameters were retrospectively collected. Radiation dosimetric parameters were tabulated. Toxicities were quantified using CTCAE v5.0. Fisher's exact test was used to assess the differences in toxicities with clinical and dosimetric parameters. P-value < 0.05 was considered significant. Results 23 patients were analyzed with a median age of 72 years (IRQ: 67-80) and 61% were females. 96% were smokers and 43% had COPD. All patients were ECOG ≤ 2. Majority of patients (96%) had early-stage primary lung cancer while 4% had pulmonary oligometastatic cancer. 39% of patients were treated on SABR-BRIDGE protocol while another 35% were medically inoperable and 26% refused surgery. A total of 23 peripheral lesions were treated with median greatest dimension of 1.7 cm (IQR: 1.4-2), ITV 4.9 cm3 (IQR: 3.6-8.4) and PTV 18.1 cm3 (IQR: 12.8-26). 87% had PTV within 1 cm form chest wall. After median follow-up of 6 months (IQR: 2-12), 52% of patients experienced grade ≤ 2 toxicities and no patients experienced ≥ grade 3. Radiation pneumonitis was the most common toxicity (35%; 5/8 with asymptomatic radiographic) followed by fatigue (30%) and chest wall pain (30%; 3/7 with grade 2). Two patients (9%) had rib fractures. Chest wall pain was significantly higher in patients with tumor diameter >1.5 cm (p = 0.02). No other significant difference was observed between clinical or dosimetric parameters and development of radiation pneumonitis or chest wall pain (p > 0.05). On the other hand, patients with ribs fractures were observed to have larger tumors (mean 3.2 vs. 1.7 cm), ITVs (mean 30 vs. 11 cm3), PTVs (mean 61 vs. 16 cm3), chest wall V30Gy (mean 4.8 vs. 0.4 cm3), and ribs V30Gy (mean 1.1 vs. 0.1 cm3). Only 1 patient had local failure after 12 months while another patient on SABR-BRIDGE underwent surgical resection after 6 months in which there were 20% viable tumor cells. Conclusion Single fraction peripheral lung SBRT is a practical and safe option with no grade ≥ 3 toxicity. Our observed toxicities are within previously reported ranges. We observed that patients with rib fractures had larger tumors and higher V30Gy to chest wall and ribs. Careful patient selection and dosimetric efforts to limit high fall-off dose to chest wall and ribs may limit these toxicities.

A pragmatic randomized controlled trial of standard care versus steroids plus standard care for treatment of pneumonia in adults admitted to Kenyan hospitals (SONIA). Wellcome Open Res 2022.

Abstract
Background: It is unclear if adjunctive steroid therapy reduces mortality in community-acquired pneumonia, as very few studies have had mortality as a primary outcome. This question has become even more relevant following demonstration of a mortality benefit of dexamethasone when used in patients with COVID-19 who had severe disease. This has led to increased prescription of steroids in adults with community acquired pneumonia in low-resource settings even when their COVID-19 diagnosis is uncertain due to low testing rates. This pragmatic parallel randomised-controlled open-label trial will determine if adjunctive low-dose steroids for treatment of adults admitted to hospital with community acquired pneumonia whose SARS-CoV-2 status is either unknown or negative reduces mortality. Methods: We will enroll and randomize 2180 patients admitted with a clinical diagnosis of community acquired pneumonia into two arms; in Stratum A-participants will receive standard care for the treatment of community acquired pneumonia. In Stratum B-participants will receive a 10-day course of low-dose oral corticosteroids in addition to standard care. All participants will be followed up to 30 days post randomization and their final status recorded (alive or dead). An immunology sub study will be conducted on a subset of the trial participants (50 per arm) to determine the correlation of pre-existing and treatment induced immune and metabolic changes with study outcomes. Discussion: Mortality among adults admitted to hospital with community acquired pneumonia in resource-limited settings is high. Steroids are readily available in these settings. If the addition of steroids to standard care for community acquired pneumonia is found to be beneficial, this easily scalable intervention would significantly reduce the currently high mortality associated with the illness.

Abstract
BACKGROUND Multidrug-resistant TB (MDR-TB) treatment takes 18-24 months and is complex, costly and isolating. We provide trial evidence on the WHO Pakistan recommendation for community-based care rather than hospital-based care.METHODS Two-arm, parallel-group, superiority trial was conducted in three programmatic management of drug-resistant TB hospitals in Punjab and Sindh Provinces, Pakistan. We enrolled 425 patients with MDR-TB aged >15 years through block randomisation in community-based care (1-week hospitalisation) or hospital-based care (2 months hospitalisation). Primary outcome was treatment success.RESULTS Among 425 patients with MDR-TB, 217 were allocated to community-based care and 208 to hospital-based care. Baseline characteristics were similar between the community and hospitalised arms, as well as in selected sites. Treatment success was 74.2% (161/217) under community-based care and 67.8% (141/208) under hospital-based care, giving a covariate-adjusted risk difference (community vs. hospital model) of 0.06 (95% CI -0.02 to 0.15; P = 0.144).CONCLUSIONS We found no clear evidence that community-based care was more or less effective than hospital-based care model. Given the other substantial advantages of community-based care over hospital based (e.g., more patient-friendly and accessible, with lower treatment costs), this supports the adoption of the community-based care model, as recommended by the WHO.

Abstract
INTRODUCTION Sub-Saharan Africa (SSA) carries the burden of the HIV epidemic, especially among adolescents and young people (AYP). Little is known about pre-exposure prophylaxis (PrEP) uptake and preferences among AYP in SSA. We describe preferences for daily and on-demand PrEP among AYP in South Africa, Uganda and Zimbabwe. METHODS A cross-sectional survey was conducted in 2019 among 13- to 24-year olds, capturing socio-demographics, HIV risk behaviours and preferences for daily or on-demand PrEP. Logistic regression models were used to estimate odds ratios, adjusting for site, sex and age. RESULTS AND DISCUSSION A total of 1330 participants from Cape Town (n = 239), Johannesburg (n = 200), Entebbe (n = 491) and Chitungwiza (n = 400) were enrolled; 673 (51%) were male, and the median age was 19 years (interquartile range 17-22 years). Of 1287 participants expressing a preference, 60% indicated a preference for on-demand PrEP with differences by site (p < 0.001), sex (p < 0.001) and age group (p = 0.003). On-demand PrEP was most preferred in Entebbe (75%), among males (65%) versus females (54%) and in older participants (62% in 18- to 24-year-olds vs. 47% in 13- to 15-year-olds). After adjusting for site, sex and age group, preference for on-demand PrEP decreased as sex frequency over the past month increased (p-trend = 0.004) and varied with the number of partners in the last 6 months, being least popular among those reporting four or more partners (p = 0.02). Participants knowing further in advance that they were likely to have sex were more likely to prefer on-demand PrEP (p-trend = 0.02). Participants having a larger age gap with their most recent partner and participants whose last partner was a transactional sex partner or client were both less likely to prefer on-demand compared to daily PrEP (p = 0.05 and p = 0.09, respectively). Participants who knew their most recent partner was living with HIV or who did not know the HIV status of their most recent partner were less likely to prefer on-demand PrEP (p = 0.05). CONCLUSIONS Our data show that AYP in four SSA communities prefer on-demand over daily PrEP options, with differences seen by site, age and sex. PrEP demand creation needs to be reviewed, optimized and tailored to socio-demographic differences and designed in conjunction with AYP.

Abstract
Engagement of adolescents and young adults (AYA) in HIV research is increasing in many settings. We organized a crowdsourcing open call to solicit examples of how AYA have been engaged in HIV research in Africa and to develop an engagement typology. We formed a steering committee, promoted the open call, organized judging and recognized finalists. We used a multi-methods approach to identify emerging themes and measure engagement. We received 95 entries from individuals in 15 countries; 74 met the eligibility criteria. More than three-quarters of entries were from AYA (55/74, 74%). Four themes characterized AYA engagement: (1) AYA were co-creators in the HIV research process. (2) AYA were involved in community-level capacity building. (3) AYA were co-leaders in minor risk research. (4) AYA used digital methods to enhance engagement. Our open call identified diverse methods of AYA engagement, which can enhance strategies used to reach AYA in African HIV studies.

Abstract
Aims: Damage of crop plants due to pathogenic attacks, postharvest crops spoilage and lethal effects of chemical pesticides has enforced scientists to find some potential natural alternative. Plants produce different types of antimicrobial peptides including defensins in response to biotic and abiotic stresses. Defensins are small cysteine rich, cationic peptide with 40-45 amino acid residues with a variety of biological activities. Hence defensins have pharmaceutical and agricultural significance especially wide range of antifungal activities.
Methodology: Nine plant species viz Brassica napus, Brassica nigra, Conyza bonariensis, Alhagi marorum, Sonchus arvensis, Brassica compestris, Eruca sativa, Cirsium arvensis and Brassica juncea were selected for the study. Four set of primers were applied on extracted genomic DNAs and four amplified genes were isolated from different plants species by PCR. The amplified genes were cloned via pTZ57R/T in E.coli. The cloned fragments were sequenced and characterized by different bioinformatics tool such as coding length and peptide sequence, site of cell aggregation, peptide physico-chemical properties, antimicrobial properties and gene expression pattern.
Result: The amplified products from B. napus, B. nigra, B. compestris, E. sativa and B. juncea were about 330 bp in length and showed upto 85% nucleotide homology to the reported defensins. Deduced amino acid sequence from Bn-Def, Es-Def Bj-Def and Bc- Def showed the conserved defensin domain. These sequences were also characterized for different characteristic like charged amino acids, pI value, shelflife and stability. Sonchus arvensis didn’t give any specific product by prescribed set of primers. However the products from Alhagi marorum was about 770 bp and B. napus was of 270 bp but both give homology below 30%.
Conclusion: This study showed that in silico characterization of deduced antimicrobial peptides from different plant species has depicted these as an effective alternative to communal therapeutics. However, further work is needed to verify defensins specific activity at protein level.

Abstract
In order to respond more effectively to the health of young people in South Africa, in 2017 the National Department of Health of South Africa released the National Adolescent & Youth Health Policy. The Policy focused on a range of health problems and recommended interventions for delivery through multiple settings and government departments. It also included specific recommendations to empower and involve young people in policy and programme implementation. Adaptation of a short course on adolescent health in lowand middle-income countries, organized annually by the London School of Hygiene and Tropical Medicine and the World Health Organization, was piloted in 2017 as one means of contributing to the implementation of the Policy. The Adolescent & Youth Health Policy short course was subsequently offered in 2018 and 2019, attracting 96 participants working on adolescent health in various organizations at national and provincial levels throughout the country. Most participants (75%) successfully completed the course, as assessed by the completion criteria that had been defined. The range of topics for the assignments selected by the participants over the 3 years reflected both the content and intent of the Policy. The evaluations of the short course indicate that it helped to create legitimacy and strengthen the capacity of various constituencies, both of which are important prerequisites for policy implementation.

Abstract
The maize crop is used as food for humans, livestock and poultries forms, it is also used in bread making, corn flakes, corn syrup, corn starch and corn oils. The field study consisted of one experimental trial, about the incidence of that insect pest complex on maize cultivar Azam during the Kharif season 2020 at the Agricultural, Research Station, Baffa, Mansehra. The trial was laid out in the Randomized Complete Block Design (RCBD), and then it was divided into three replications. The result obtained from the trial showed that a number of the pest species were recorded during the experimental period; however, the population was noticed at a low level. The obtained insect species were corn leaf aphid (6.90 ± 5.5) per square inch, corn leafhopper (1.32 ± 0.63), maize stem borer (0.63 ± 0.29), corn flea beetle (0.43 ± 0.28), Thrips (0.38 ± 0.22), Hairy caterpillar (0.21 ± 0.22), Grasshopper (0.17 ± 0.11) and shoot fly (0.11 ± 0.08) throughout the season.

The landscape of neurophysiological outcome measures in ALS interventional trials: A systematic review. Clin Neurophysiol 2022; 137:132-141. [PMID: 35313253 PMCID: PMC10166714 DOI: 10.1016/j.clinph.2022.02.020] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 02/11/2022] [Accepted: 02/18/2022] [Indexed: 12/28/2022]
Abstract
OBJECTIVE We collated all interventional clinical trials in amyotrophic lateral sclerosis (ALS), which utilised at least one neurophysiological technique as a primary or secondary outcome measure. By identifying the strengths and limitations of these studies, we aim to guide study design in future trials. METHODS We conducted and reported this systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eight databases were searched from inception. In total, 703 studies were retrieved for screening and eligibility assessment. RESULTS Dating back to 1986, 32 eligible interventional clinical trials were identified, recruiting a median of 30 patients per completed trial. The most widely employed neurophysiological techniques were electromyography, motor unit number estimation (including motor unit number index), neurophysiological index and transcranial magnetic stimulation (including resting motor threshold and short-interval intracortical inhibition). Almost 40% of trials reported a positive outcome with respect to at least one neurophysiological measure. The interventions targeted either ion channels, immune mechanisms or neuronal metabolic pathways. CONCLUSIONS Neurophysiology offers many promising biomarkers that can be utilised as outcome measures in interventional clinical trials in ALS. When selecting the most appropriate technique, key considerations include methodological standardisation, target engagement and logistical burden. SIGNIFICANCE Future trial design in ALS would benefit from a standardised, updated and easily accessible repository of neurophysiological outcome measures.

Characteristics of HIV post‐exposure prophylaxis recipients at six English sexual health clinics during COVID‐19. HIV Med 2022; 23:1103-1107. [PMID: 35403371 PMCID: PMC9111810 DOI: 10.1111/hiv.13308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Revised: 01/27/2022] [Accepted: 03/14/2022] [Indexed: 11/30/2022]
Abstract
Objectives Disruption to sexual health services during the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2; coronavirus disease 2019 [COVID‐19]) pandemic may have adversely affected the provision of HIV post‐exposure prophylaxis (PEP), possibly leading to increased HIV transmission. Globally, services have reported a reduction in the number of PEP prescriptions dispensed during lockdowns, although it is unclear why. Our primary objective was to describe the temporal change in weekly HIV PEP dispensed at six English sexual health clinics in 2020. Methods We performed a cross‐sectional review of PEP prescriptions from six English centres during 2020. Results During 2020, 2884 PEP prescriptions were dispensed across the six centres studied, a fall of 34.5% from the 4403 PEP prescriptions in 2019. Before the COVID‐related lockdown in 2020, the PEP dispensed was stable at 82.5 per week. Following the first lockdown, this fell to a nadir of 13 in week 14 (Figure 1). Prescriptions rose to a peak of 79 in week 37 and then declined to 32 prescriptions in the last week of 2020. There was no difference in the following characteristics of PEP recipients before and during the first lockdown: age, ethnicity, country of birth or the service the recipient attended. Conclusion Whatever the reason for the fall in PEP seen in England over 2020, it is essential that HIV testing and access to HIV prevention is maintained for those in need.

Abstract
Abstract
Introduction
The Chest X-Ray (CXR) is a common and central initial investigation for any patient that has been admitted via Accident and Emergency (A&E). In the context of elderly care, it is a useful measure of a patient’s baseline functional status as well as a tool for cancer surveillance and other aspects of clinical care. Accurate documentation of CXR review is also imperative for closed loop communication of clinical information amongst a multi-disciplinary team.
Methods
Twenty-eight random inpatients in a local NHS Trust Healthcare of Older People (HCOP) department were selected to be part of this two-cycle study. Using hospital database records, the CARESTREAM imaging system and patient clinical documentation, data including the following was collected: whether a CXR was completed, was CXR review documented in patient notes and initial reason for admission. As per local practice, all acute HCOP admissions should undergo a CXR and have an image review clearly documented in patients’ clinical noting. The established target was 95% compliance for both. Following intervention by way of ward poaters and presentation at a local quality improvement meeting the cycle was repeated to ascertain improvement in compliance.
Results
22 (79%) HCOP patients had a CXR on admission. Of those completed CXRs, only 6 (27%) of these showed evidence of review (documentation in clinical noting). Following the above mentioned interventions, 25 (89%) of HCOP patients had a CXR on admission, showing an improvement. Of those completed CXRs, 20 (80%) showed evidence of documented clinical review– once again showing improvement.
Conclusions
CXRs and their accurate documentation is an important aspect of the holistic care of the HCOP patient. Ensuring that compliance for completing the scan and documenting results should be a priority in clinical quality and safety. Our interventions have shown an improvement in compliance and resulted in sustainable change.

Abstract
Pre-exposure prophylaxis (PrEP) is an HIV-prevention strategy recommended for those at high-risk of infection, including adolescents and young people (AYP). We explored how PrEP roll-out could influence sexual risk behaviour among AYP in East and southern Africa. Twenty-four group discussions and 60 in-depth interviews were conducted with AYP between 13 and 24 years old, recruited from community settings in Uganda, Zimbabwe and South Africa, from September 2018 to January 2019. Participants perceived that PrEP availability could change sexual behaviour among AYP, influencing: (1) condom use (increased preference for condomless sex, reduced need and decrease in use of condoms, relief from condom use discomfort, consistent condom use to curb sexually transmitted infections and pregnancies); (2) sexual activities (increase in sexual partners and sexual encounters, early sexual debut, sexual experimentation and peace of mind during risky sex, sexual violence and perversion); (3) HIV risk perception (neglect of other HIV prevention strategies, unknown sexual partner HIV status, adoption of PrEP). PrEP initiation may be associated with increased interest in sexual activities and risky sexual behaviour among AYP. PrEP should be included as part of a combination package of HIV prevention strategies for AYP with methods to prevent other sexually transmitted infections and unwanted pregnancies.

Abstract
Brucella ceti infection is associated with a variety of disease outcomes in cetaceans globally. Multiple genotypes of B. ceti have been identified. This retrospective aimed to determine if specific lesions were associated with different B. ceti DNA sequence types (STs). Characterization of ST was performed on 163 samples from 88 free-ranging cetaceans, including common bottlenose dolphin Tursiops truncatus (T.t.; n = 73), common short-beaked dolphin Delphinus delphis (D.d.; n = 7), striped dolphin Stenella coeruleoalba (n = 3), Pacific white-sided dolphin Lagenorhynchus obliquidens (n = 2), sperm whale Physeter macrocephalus (n = 2), and harbour porpoise Phocoena phocoena (n = 1), that stranded along the coast of the US mainland and Hawaii. ST was determined using a previously described insertion sequence 711 quantitative PCR. Concordance with 9-locus multi-locus sequence typing was assessed in a subset of samples (n = 18). ST 26 was most commonly identified in adult dolphins along the US east coast with non-suppurative meningoencephalitis (p = 0.009). Animals infected with ST 27 were predominately perinates that were aborted or died shortly after birth with evidence of in utero pneumonia (p = 0.035). Reproductive tract inflammation and meningoencephalitis were also observed in adult T.t. and D.d. with ST 27, though low sample size limited interpretation. ST 23 infections can cause disease in cetacean families other than porpoises (Phocoenidae), including neurobrucellosis in D.d. In total, 11 animals were potentially infected with multiple STs. These data indicate differences in pathogenesis among B. ceti STs in free-ranging cetaceans, and infection with multiple STs is possible.

Abstract
BACKGROUND Critical illness is often followed by mental and physical impairments. We aimed to assess the health-related quality of life (HRQoL), symptoms of anxiety and depression, and physical function in critically ill patients after discharge from the intensive care unit. METHODS For this prospective cohort study we included all available adult patients admitted to the ICU for >24 h during a 12-month period. Home visits took place at 3 and 12 months after discharge from the hospital and included Short-Form Health Survey (SF-36), Hospital Anxiety and Depression Scale, and Chelsea Critical Care Assessment Too (CPAx). RESULTS We visited 79 patients at 3 and 53 at 12 months. In patients with data from both visits the mental components SF-36 scores (median (IQR)) were 55 (43-63) at 3, and 58.5 (49.5-64) at 12 months; physical component SF-36 scores were 35 (28-45) at 3, and 36 (28-42) at 12 months. SF-36 subdomains of mental health, social functioning, and role emotional were close to normal. Vitality, bodily pain, general health, physical functioning, and role physical were severely affected. Incidences of anxiety and depression symptoms were 16%/8% at 3 and 13%/8% at 12 months) and physical function (CPAx) was 47 at both time points). CONCLUSION We found no change in HRQoL, anxiety, and depression, or physical function from 3 months to 1 year. Physical health-related quality of life was impaired at both time points. Subdomain scores for physical health-related quality of life were affected more than mental domains at both time points.

Refeeding syndrome in surgical patients post initiation of artificial feeding, a prospective cohort study in a low-income country. Clin Nutr ESPEN 2021; 46:210-215. [PMID: 34857199 DOI: 10.1016/j.clnesp.2021.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 10/03/2021] [Accepted: 10/06/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND & AIMS South Africa's inequitable history has contributed to a malnourished population, further aggravated by high levels of violence and economic uncertainty culminating in a population suffering the sequelae of poverty. The perceived notion is that malnutrition places the South African population at greater risk for development of refeeding syndrome. This study aimed to identify the incidence of refeeding syndrome in the South African population. METHODS All patients admitted into the surgical intensive care unit from 1 November 2019 to 30 September 2020, were screened using the National Institute for Health and Care Excellence (NICE) refeeding risk criteria. Patients started on artificial feeds with one or more risk factors were included in the study. The syndrome was confirmed using the King's College criteria and compared with the American Society for Parenteral and Enteral Nutrition (ASPEN) criteria for refeeding syndrome. RESULTS 200 Patients were included in this study. The median age of the sample population was 41 years (IQR 30-58) with a male predominance (63%). All patients included had one or more risk factors and 62 (31%) of patients fulfilled the NICE criteria. The sensitivity of the NICE criteria was 33% and specificity was 70%. The most common risk factors identified were little or no nutritional intake for >5 days (55%) followed by a history of alcohol abuse, drugs including insulin, chemotherapy, diuretics or antacids (18%). Specificity values for all risk factors were >80% apart from little or no nutritional intake for >5 days which had a specificity of 64.2%. Sensitivity values for all risk factors were low. 84.5% of patients received artificial nutritional support in the form of enteral feeds, 9% parenteral and 6.5% both enteral and parenteral feeds. A total of 146 patients required electrolyte supplementation. Three patients fulfilled the King's College criteria and one subsequently died. In comparison, 25 patients fulfilled the ASPEN criteria and 3 demised. CONCLUSION Due to the low sensitivity and specificity of the NICE criteria, we advise that it be used merely as a guideline to identify patients at risk of refeeding syndrome and one should remain vigilant in patients with any risk factors present. Due to the small number of patients who fulfilled the King's College criteria and significant difference in incidence when compared to the ASPEN definition, a conclusion regarding the accuracy of both diagnostic criteria could not be made. We recommend a review of the current definition and a global adoption of an agreed criteria for the estimation of the true prevalence.

Abstract
There are different opinions around the World regarding the zoonotic capability of H3N8 equine influenza viruses. In this report, we have tried to summarize the findings of different research and review articles from Chinese, English, and Mongolian Scientific Literature reporting the evidence for equine influenza virus infections in human beings. Different search engines i.e. CNKI, PubMed, ProQuest, Chongqing Database, Mongol Med, and Web of Knowledge yielded 926 articles, of which 32 articles met the inclusion criteria for this review. Analyzing the epidemiological and Phylogenetic data from these articles, we found a considerable experimental and observational evidence of H3N8 equine influenza viruses infecting human being in different parts of the World in the past. Recently published articles from Pakistan and China have highlighted the emerging threat and capability of equine influenza viruses for an epidemic in human beings in future. In this review article we have summarized the salient scientific reports published on the epidemiology of equine influenza viruses and their zoonotic aspect. Additionally, several recent developments in the start of 21st century, including the transmission and establishment of equine influenza viruses in different animal species i.e. camels and dogs, and presumed encephalopathy associated to influenza viruses in horses, have documented the unpredictable nature of equine influenza viruses. In sum up, several reports has highlighted the unpredictable nature of H3N8 EIVs highlighting the need of continuous surveillance for H3N8 in equines and humans in contact with them for novel and threatening mutations.

Safety and outcomes of routine endovascular thrombectomy in large artery occlusion recorded in the SITS Register: An observational study. J Intern Med 2021; 290:646-654. [PMID: 33999451 DOI: 10.1111/joim.13302] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Revised: 03/26/2021] [Accepted: 03/31/2021] [Indexed: 01/19/2023]
Abstract
BACKGROUND AND OBJECTIVE We aimed to evaluate the safety and outcomes of thrombectomy in anterior circulation acute ischaemic stroke recorded in the SITS-International Stroke Thrombectomy Register (SITS-ISTR) and compare them with pooled randomized controlled trials (RCTs) and two national registry studies. METHODS We identified centres recording ≥10 consecutive patients in the SITS-ISTR with at least 70% of available modified Rankin Scale (mRS) at 3 months during 2014-2019. We defined large artery occlusion as intracranial internal carotid artery, first and second segment of middle cerebral artery and first segment of anterior cerebral artery. Outcome measures were functional independence (mRS score 0-2) and death at 3 months and symptomatic intracranial haemorrhage (SICH) per modified SITS-MOST. RESULTS Results are presented in the following order: SITS-ISTR, RCTs, MR CLEAN Registry and German Stroke Registry (GSR). Median age was 73, 68, 71 and 75 years; baseline NIHSS score was 16, 17, 16 and 15; prior intravenous thrombolysis was 62%, 83%, 78% and 56%; onset to reperfusion time was 289, 285, 267 and 249 min; successful recanalization (mTICI score 2b or 3) was 86%, 71%, 59% and 83%; functional independence at 3 months was 45.5% (95% CI: 44-47), 46.0% (42-50), 38% (35-41) and 37% (35-41), respectively; death was 19.2% (19-21), 15.3% (12.7-18.4), 29.2% (27-32) and 28.6% (27-31); and SICH was 3.6% (3-4), 4.4% (3.0-6.4), 5.8% (4.7-7.1) and not available. CONCLUSION Thrombectomy in routine clinical use registered in the SITS-ISTR showed safety and outcomes comparable to RCTs, and better functional outcomes and lower mortality than previous national registry studies.

Abstract
Objective To evaluate the knowledge, attitude, and practice of general population for Corona virus disease 19 (COVID-19). Methods A total of 950 participants submitted an online self-administered questionnaire, which was developed through literature search and validated. The online survey link was distributed through various social media platforms (WhatsApp, Instagram, Facebook, LinkedIn, Twitter, Snapchat, Pinterest, and Tumblr). And 861 forms were included in the study after checking for completion of relevant response from participants, whereas 89 forms were excluded. The data were analyzed through Statistical Package for Social Sciences. Descriptive statistics were performed for percentage and frequency determination of quantitative and qualitative variables. Spearman's correlation and Chi square test were performed to control confounders and association of knowledge, attitude, and practices with gender and education level. The P value <0.05 was considered as statistically significant. Results More than two third of the population was aware of COVID-19 and three fourth had had bachelor's degrees, whereas 18% had master level education. 85% have not attended any courses, awareness campaigns, and lectures to inculcate recent and updated knowledge. 83% believed that COVID-19 is a serious threat to the community; hence, prevention strategies should be adopted. There was no significant relationship (p = 0.23) between knowledge, attitude, and practice levels with gender, whereas a significant relationship (p = 0.01) was noted with education of participant. Similarly, a significant relationship (p = 0.00) was seen between knowledge and practices of participants toward COVID-19. Conclusion The studied population displayed adequate knowledge, attitude, and practice to combat COVID-19. However, we also find a knowledge gap between information source and perception of COVID-19 among our study participants. Therefore, there is a critical need for effective education and widespread public campaigns aiming to enhance relevant and contemporary information related to prevention and management of COVID-19.

Abstract
The present study reports on seasonal and spatial variations in diversity, distribution and abundance of dinoflegellates and indicates the presence of HAB species in Pakistan waters. A total of 179 taxa, recorded in this study from offshore and near-shore waters, belong to 41 genera in 26 families and 10 orders. The high species count (149 species) was recorded from Manora Island offshore station (MI-1) and 105 spp, 109 spp and 115 spp were encountered from the Mubarak village offshore station (MV-1), Manora near shore station (MI-2) and Mubarak Village near-shore station (MV-2) respectively. Tripos furca was the dominant and frequently occurring species (> 1 x103 to > 25 x103 cells L-1 from coastal and >1x 105 cells L-l from near-shore stations) in addition to less abundant Alexandrium catenella, Alexandrium sp., Alexandrium minutum, and Prorocentrum micans (>103 to 25x 103cells/L). Another 44 species occurred in relatively low numbers (<103 cell L-l). Seventy species were found throughout the study period at all four stations. High number of species in three genera (Tripos (38), Protoperidinium (34) and Prorocentrum (20) was recorded. Potently toxic (16 genera 43 species) and HAB related (19 genera and 30 species) dinoflagellate taxa were also recorded. The percent contribution of dinoflagellates in total phytoplankton population generally remained below 20% except for a few instances. Manora Island stations had comparatively higher Shannon index and equitability and slightly lower dominance index. The PCA plot showed strong positive correlation among chlorophyll-a concentration, dissolved oxygen, total number of phytoplankton and dinoflagellates.

Exploring Perceived Barriers and Facilitators of PrEP Uptake among Young People in Uganda, Zimbabwe, and South Africa. ARCHIVES OF SEXUAL BEHAVIOR 2021; 50:1729-1742.

Abstract
Pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy. Few studies have explored adolescents and young people's perspectives toward PrEP. We conducted 24 group discussions and 60 in-depth interviews with males and females aged 13-24 years in Uganda, Zimbabwe, and South Africa between September 2018 and February 2019. We used the framework approach to generate themes and key concepts for analysis following the social ecological model. Young people expressed a willingness to use PrEP and identified potential barriers and facilitators of PrEP uptake. Barriers included factors at individual (fear of HIV, fear of side effects, and PrEP characteristics), interpersonal (parental influence, absence of a sexual partner), community (peer influence, social stigma), institutional (long waiting times at clinics, attitudes of health workers), and structural (cost of PrEP and mode of administration, accessibility concerns) levels. Facilitators included factors at individual (high HIV risk perception and preventing HIV/desire to remain HIV negative), interpersonal (peer influence, social support and care for PrEP uptake), community (adequate PrEP information and sensitization, evidence of PrEP efficacy and safety), institutional (convenient and responsive services, provision of appropriate and sufficiently resourced services), and structural (access and availability of PrEP, cost of PrEP) levels. The findings indicated that PrEP is an acceptable HIV prevention method. PrEP uptake is linked to personal and environmental factors that need to be considered for successful PrEP roll-out. Multi-level interventions needed to promote PrEP uptake should consider the social and structural drivers and focus on ways that can inspire PrEP uptake and limit the barriers.

Abstract
Introduction In the United Kingdom, the move from trainee to consultant psychiatrist can be both exciting and daunting. Trainee psychiatrists have access to support and weekly supervision that is not available to consultants. Having an organised meeting for new consultants could help bridge this gap with peer-led support. Objectives Improving support and guidance to new consultants Networking with peers Promoting wellbeing, good clinical practice and career development Methods We identified a group of 85 consultants in their first five years of practice. Meetings were held online using videoconference. Senior leaders presented at each meeting, with a group discussion at the end. We surveyed attendees using an online platform. Results We had excellent attendance rates from the group, with 30 to 45 consultants attending each webinar. Over 60% of attendees had been a consultant for less than a year. For 90%, this was their first experience of a new consultant forum. Attendees gave excellent feedback (Table). Being able to meet consultants from different specialties, hearing career stories from senior leaders and how they have managed the COVID-19 pandemic were cited as benefits.Table: Feedback scores (0 = not useful to 100 = very useful) | Statement | Score | The forum helped me feel supported | 75 | Topics covered are relevant to me | 79 | I feel more connected with colleagues | 71 |
![]() Conclusions The forum was popular and the feedback was excellent. Using an online format worked well and made it easier to organise and plan sessions. There is potential to implement similar fora for other senior psychiatrists across Europe.
