Abstract

Contains fulltext : 80963.pdf (Publisher’s version ) (Open Access) BACKGROUND: The extent to which mortality differs following individual acquired immunodeficiency syndrome (AIDS)-defining events (ADEs) has not been assessed among patients initiating combination antiretroviral therapy. METHODS: We analyzed data from 31,620 patients with no prior ADEs who started combination antiretroviral therapy. Cox proportional hazards models were used to estimate mortality hazard ratios for each ADE that occurred in >50 patients, after stratification by cohort and adjustment for sex, HIV transmission group, number of antiretroviral drugs initiated, regimen, age, date of starting combination antiretroviral therapy, and CD4+ cell count and HIV RNA load at initiation of combination antiretroviral therapy.

Abstract

Background: The extent to which the prognosis for AIDS and death of patients initiating highly active antiretroviral therapy (HAART) continues to be affected by their characteristics at the time of initiation (baseline) is unclear. Methods: We analyzed data on 20,379 treatment-naive HIV-1- infected adults who started HAART in 1 of 12 cohort studies in Europe and North America (61,798 person-years of follow-up, 1844 AIDS events, and 1005 deaths). Results: Although baseline CD4 cell count became less prognostic with time, individuals with a baseline CD4 count 350 cells/μL (hazard ratio for AIDS = 2.3, 95% confidence interval [CI]: 1.0 to 2.3; mortality hazard ratio = 2.5, 95% CI: 1.2 to 5.5, 4 to 6 years after starting HAART). Rates of AIDS were persistently higher in individuals who had experienced an AIDS event before starting HAART. Individuals with presumed transmission by means of injection drug use experienced substantially higher rates of AIDS and death than other individuals throughout follow-up (AIDS hazard ratio = 1.6, 95% CI: 0.8 to 3.0; mortality hazard ratio = 3.5, 95% CI: 2.2 to 5.5, 4 to 6 years after starting HAART). Conclusions: Compared with other patient groups, injection drug users and patients with advanced immunodeficiency at baseline experience substantially increased rates of AIDS and death up to 6 years after starting HAART.

Abstract

We reported a case of a 30-year-old man who reportedly sustained electrical burns and fell from a high voltage electric pole about 50 meter high onto a metal that caused impalement injury. In addition, he sustained full-thickness burns of the right upper limb (7%), the right hemithorax, the perineum (sparing the penis), the anterior abdominal wall and the lateral aspect of both thighs. There was 43% burned surface area in total. Radiographic examination revealed a slender curved object extending from his perineum into the pelvis. The management of this case was a challenging one which was described in this article.

8. Radiotherapy in Managing Metastatic Hepatocellular Carcinoma With Cardiac Involvement and Pulmonary Tumor Thromboemboli: A Case Report.

Author

Chow Z, Amoah E, Hao Z, and Kudrimoti M

Abstract

Hepatocellular carcinoma (HCC) is the most common liver cancer and presents various degrees of aggressiveness. In this case study, we reported the management of an aggressive HCC patient who was a young immigrant from a hepatitis B endemic country with locally advanced HCC with portal involvement at presentation. Patient was initially managed with Yttrium-90 (Y-90) instillation, then systemic treatment when he had disease progression. Despite multiple lines of systemic treatments, patient continued to progress and developed significant cardiac involvement and pulmonary tumor thromboemboli. His course of treatment was further complicated by hemoptysis, presumably from hemorrhagic tumor thromboemboli. Patient became ineligible for systemic treatment due to the risk of hemoptysis, thus, subsequently managed with a course of palliative radiotherapy. Unfortunately, patient developed hemorrhagic shock, cardiac failure, and septic shock during radiation treatment and expired shortly afterward. In this case report, we discussed multi-modal treatments, including Y-90, systemic treatment, and radiotherapy, in managing complicated and aggressive HCC. We also reported risk factors, prognostic factors, efficacy of Y-90 instillation and the necessity of a personalized treatment approach. In conclusion, there is no consensus on managing patients with metastatic HCC with cardiac and pulmonary involvement currently. Treatment modalities are often highly personalized and require multi-disciplinary discussion., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Chow et al.)

Abstract

Malaria is an acute febrile illness. It is a dangerous disease that contributes to millions of hospital visits and hundreds of thousands of deaths, especially in children residing in sub-Saharan Africa. In a non-immune individual, symptoms usually appear 10-15 days after the infective mosquito bite. The first symptoms-fever, headache, and chills-may be mild and difficult to recognize as malaria. If not treated within 24 h, P. falciparum malaria can progress to severe illness, often leading to death. Children with severe malaria frequently develop one or more of the following symptoms: severe anaemia, respiratory distress in relation to metabolic acidosis, or cerebral malaria. In adults, multi-organ involvement is also frequent. In malaria endemic areas, people may develop partial immunity, allowing asymptomatic infections to occur. Haematological changes are well-recognised with malarial infection however background haemoglobinopathy, nutritional status, demographic factors and malaria immunity play a major role in specific changes in that geographical region. Artemisinin derivatives are new generation antimalarial drugs they are used in the treatment of acute attacks of severe malaria including cerebral malaria. Information on the safety of these new antimalarial drugs on body function is still scanty. Haematological parameters are well studied in P. falciparum infection, but now recent studies have indicated that these changes do occur in P. vivax infection also. Hematological profile together with microscopy will enable rapid diagnosis, prompt treatment and further complications can be avoided. This current review is aimed at providing an up-to-date information on the role of malaria and anti-malarial drugs on haematological parameters especially thrombocytopenia., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interests., (© Indian Society for Parasitology 2022, Springer Nature or its licensor (e.g. a society or other partner) holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Abstract

Background: Attachment refers to an infant's innate tendency to seek comfort from their caregiver. Research shows that attachment is important in promoting healthy social and emotional development. Many parenting interventions have been developed to improve attachment outcomes for children. However, numerous interventions used in routine practice have a limited evidence base, meaning that we cannot be sure if they are helpful or harmful., Objectives: This research aimed to conduct a large-scale survey to identify what interventions are being used in UK services to improve child attachment; conduct a systematic review to evaluate the evidence for parenting attachment interventions; and develop recommendations for future research and practice., Design and Methods: We worked closely with our Expert Reference Group to plan a large-scale survey focused on relevant UK services. We then conducted two systematic reviews. One searched for all randomised controlled trial evidence for any attachment parenting intervention. The second searched for all research for the top 10 routinely used interventions identified from the survey., Results: The survey collected 625 responses covering 734 UK services. The results identified the 10 most commonly used interventions. The responses showed a limited use of validated measures and a wide variety of definitions of attachment. For the first review, seven studies were included from 2516 identified records. These were combined with results from previous reviews conducted by the team. Meta-analyses showed that, overall, parenting interventions are effective in reducing disorganised attachment (pooled odds ratio 0.54, 95% confidence interval 0.39 to 0.77) and increasing secure attachment (pooled odds ratio 1.85, 95% confidence interval 1.36 to 2.52). The second review searched the literature for the top 10 routinely used interventions identified by the survey; 61 studies were included from 1198 identified records. The results showed that many of the most commonly used interventions in UK services have a weak evidence base and those with the strongest evidence base are not as widely used., Conclusions: There is a need for better links between research and practice to ensure that interventions offered to families are safe and effective. Possible reasons for the disparity include the cost and accessibility of training. There is also a need for improved understanding by professionals regarding the meaning of attachment., Limitations: Although the survey had good geographical spread, most respondents were based in England. For review 2 we were unable to access a large number of papers; however, we conducted extensive reference checking to account for this., Future Work: There is a need for robust research to test the efficacy of routinely used attachment interventions. Research could also explore why routinely used interventions are not consistently subject to thorough evaluation; how to embed dissemination, cost-effectiveness, fidelity and sustainability into research; and how to keep clinical practice up to date with research developments., Study Registration: This study is registered as PROSPERO CRD42019137362., Funding: This project was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment ; Vol. 27, No. 2.

Abstract

In the search for alternatives to wood fuel, to meet the bio-energy requirement of an ever-increasing global population, the International Network for Bamboo and Rattan has supported farmers in many tropical countries to establish plantations of Beema bamboo (a tissue-cultured clone from Bambusa vulgaris) and Oxytenanthera abyssinica for bio-energy production. The quality of these species as solid biofuels is unknown due to the absence of data on their physico-thermal and emission characteristics. Using the American Standard for Testing and Materials and other internationally accepted standards, their ultimate and proximate analysis, and physico-thermal and emission properties were evaluated. Beema bamboo and O. abyssinica have high Hydrogen, organic and fixed Carbon contents and low quantities of ash, moisture content, volatile matter, Oxygen, Nitrogen and Sulphur. This will contribute to their heating values and low oxide emissions. Based on their High Heating Values (Beema bamboo = 23.22 MJ/kg; O. abyssinica = 23.26 MJ/kg), the species will be suitable for high energy-using applications. The Particulate Matter and Carbon Monoxide concentrations (Beema bamboo: 90 ug/m3 and 2.83 ppm respectively; O. abyssinica: 77.33 ug/m3 and 3.20 ppm respectively) are lower than the threshold (35000 ug/m3 and 9 ppm respectively) approved by the United States Environmental Protection Agency. These properties make the species good raw materials for solid biofuel which is safe for indoor use. Their use will contribute to reducing pressure on tropical forests for wood fuel and the health hazards associated with fossil fuel use., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2022 Boadu et al.

Abstract

Background: Adolescent pregnancy is a public health challenge that has well-defined causes, associated health risks, and social and economic consequences for adolescent, their families, communities, and society. The purpose of this scoping review is to summarize studies published on socio-cultural determinants of adolescent pregnancy in Ghana., Methods: Search for records was done in four major databases, including PubMed CENTRAL, Science Direct and JSTOR. Records from Google and Google Scholar were also added, and results and findings from published and unpublished studies were included. All the 22 studies that met the eligibility criteria, were critically appraised. The guidelines for conducting scoping reviews by Arksey and O'Malley were followed., Results: The result revealed that poverty, peer influence, low level of education, dysfunctional family, lack of communication between parents and their daughters, lack of sexual and reproductive health education, child marriage, coerced sex, misconception and non-usage of contraceptives, and decline in cultural values such as puberty rites and virginity inspection are some of the determinants of adolescent pregnancy in Ghana. The study also showed that there is a lack of high-quality observational studies that adjust for confounding variables., Conclusion: Interventions and policies should be designed to take into consideration the needs, context, and background of adolescents. Programmes to enhance adolescent reproductive health need to consider multilevel factors such as person, family, community, institutions, national, and global issues that affect such programmes., (© 2022.

Abstract

Introduction: The COVID-19 pandemic has exacted an appreciable burden on health systems globally including adverse psychological impacts on health workers. This study sought to assess COVID-19-related fear, depression, anxiety and stress among hospital staff, potential factors that may help reduce its psychological effects and their personal coping strategies. The study will help to highlight the psychological impact of COVID-19 on Ghanaian health workers and indirectly serve as a needs assessment survey for input to support affected staff and the broader health system., Methods: A cross-sectional survey was conducted among health workers in three hospitals in the Ashanti Region of Ghana from 11 July 2020 to 12 August 2020. Demographic data and scores from the validated DASS-21 and Fear of COVID-19 scales and two other scales developed de novo were entered from 272 self-administered questionnaires and analyzed for means, frequencies and proportions. Fisher's exact test analysis was done to ascertain associations between selected independent variables and depression, anxiety, stress and fear. Parametric and non-parametric tests were used to compare the mean and median scores of the outcome variables across the three study hospitals., Results and Conclusion: Over 40% of respondents had fear while 21.1%, 27.8% and 8.2% had depression, anxiety and stress, respectively. Positive attitudes from colleagues and the government's tax-free salary relief were some factors said to reduce the psychological effects while over half of participants indicated praying more often as a coping strategy. There is a need for the health system to recognize the presence of these adverse psychological effects in health workers and take pragmatic steps to address them., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

Abstract

Introduction: Despite efforts to combat hypertension by pharmacotherapy, hypertension control rates remain low. Lifestyle modifications of individuals diagnosed with hypertension have prospects for the prevention and control of hypertension. This study assessed the effect of modifiable lifestyle factors on blood pressure control among adults in urban Accra., Methods: In this cross-sectional study, 360 diagnosed hypertensive patients who were ≥18 years old, selected from two secondary-level referral hospitals in the Greater Accra Region, were interviewed. Demographic information, diet components, and exercise assessments as well as blood pressure measurements were taken. Chi-squared tests and binomial logistic regression were used to determine the association between demographic and lifestyle factors with blood pressure control. Area under the receiver-operator curves (AUROC) was used to identify lifestyle factors predicting optimal blood pressure control among patients diagnosed with hypertension., Results: Approximately 54.2% of participants had no knowledge of either causes or complications of hypertension. Similarly, 52.5% of patients that had not achieved blood pressure control lacked knowledge of causes or complications of hypertension. Longer time since diagnosis of 2-5 years (AOR = 0.08 (95% CI: 0.01-0.47)) and 6-10 years (AOR = 0.08 (95% CI: 0.01-0.50)) and diets, mainly composed of meat (AOR = 0.13 (95% CI: 0.02-0.70)) and starch (AOR = 0.14 (95% CI: 0.03-0.79)), predicted poor blood pressure control compared to patients diagnosed within a year and diets without meat and starch as main components, respectively. Additionally, engaging in some physical activity of 30 minutes to one hour (AOR = 5.64 (95% CI: 2.08-15.32)) and more than an hour (AOR = 11.38, 95% CI: 2.01-64.47)) predicted blood pressure control., Conclusion: The study concludes that increased physical activity, abstaining from alcohol and smoking, increased intake of fruits and vegetables, and reduced intake of carbohydrates, meat, and fat have a positive influence on blood pressure control. Lifestyle modifying factors have a key role in complementing pharmacotherapy in hypertension control., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2020 Emefa Modey Amoah et al.)

Abstract

Nasopharyngeal cancer (NPC) is associated with Epstein Barr virus (EBV) infection. However different viral strains have been implicated in NPC worldwide. This study aimed to detect and characterize EBV in patients diagnosed with NPC in Ghana. A total of 55 patients diagnosed with NPC by CT scan and endoscopy were age-matched with 53 controls without a known oncological disease. Venous blood was collected from the study participants and DNA extracted from the blood samples. Detection of EBV and genotyping were done by amplifying Epstein Barr nuclear antigen 1 (EBNA-1) and Epstein Barr nuclear antigen 2 (EBNA-2), respectively, using specific primers. Viral load in patients and controls was determined using real-time polymerase chain reaction. EBV positivity in controls (92%) was significantly greater than that of NPC patients (67%) (χ2 = 19.17, p < 0.0001), and viral infection was independent of gender (χ2 = 1.770, p = 0.1834). The predominant EBV genotypes in patients and controls were genotype 2 (52%) and genotype 1 (62%), respectively. Median EBV load was significantly higher in NPC patients than the control group ( p < 0.01). In summary, prevalence of EBV genotype 2 infection was higher in NPC patients than the control group. Assessment of EBV load may be used as a biomarker for the diagnosis of NPC.

Abstract

Background: Maternal obesity in pregnancy has been linked with increased risk of pregnancy induced hypertension (PIH). In some tertiary referral hospitals in Ghana, PIH is the leading cause of institutional maternal mortality., Objective: To evaluate blood pressure changes during pregnancy amongst different body mass index (BMI) groups and how this relates to the risk of developing PIH., Methods: Women who had a dating ultrasound before 20 weeks gestation and registering for antenatal care at the Korle-Bu Teaching Hospital in Accra, between February and December 2013 and met the inclusion criteria were recruited into a cohort study. BMI was assessed at baseline. Blood pressure measurements were taken at (±2) 24, 28 and 36 weeks. Primary outcome measure of interest during follow-up was a diagnosis of PIH at these points. BP changes during follow up at the three points were measured. Descriptive analysis of baseline factors was carried out and compared for the BMI groups. Relative risk (RR) of PIH was estimated at 95% confidence interval., Results: Mean (SD) age for the 361 women was 30.9 (4.8) years. Incidence of PIH amongst the cohort was 10.5% (95% CI: 7.45% - 14.45%) and 40.4% and 33.0% of them were overweight and obese respectively at baseline. Pregnant women who were obese at baseline had a three-fold increased risk of PIH compared to those with normal BMI [RR = 3.01 (1.06-8.52), p = 0.04]., Conclusion: Obese women have a significantly increased risk of PIH. Women should be screened at booking for obesity status. Antenatal protocols should have interventions for prevention or early detection of obesity and management of obesity to improve outcomes.

17. Regioselective 1,4-Conjugate Addition of Grignard Reagents to α,β-γ,δ-Dienones and α,β-γ,δ-Dienyl Thiol Esters.

Author

Amoah E and Dieter RK

Abstract

Alkyl Grignard reagents (Et, n Bu, i Pr, cyclohexyl), with the exception of t BuMgCl, undergo exclusive or exceptionally highly regioselective 1,4-addition reactions to α,β-γ,δ-unsaturated ketones, while aryl and heteroaryl Grignard reagents give mixed results ranging from exclusive 1,4-addition (1-naphthyl, 2-N-methylpyrrolyl) to regioselective 1,2-addition (2-furyl, 2:1). All alkyl, aryl, and heteroaryl Grignard reagents examined gave exclusive 1,4-addition reactions with α,β-γ,δ-unsaturated thiol esters, with the exception of t BuMgCl, which gave an 80:20 mixture of 1,4:1,6-addition products. The high chemo- and regioselectivity observed for these reactions is attributed to a radical or radical-like pathway for the alkyl Grignard reagents and possibly a carbanion pathway for aryl Grignard reagents. The α,γ-dienyl thiol esters provide for a one-pot tandem 1,4-addition-nucleophilic acyl substitution reaction sequence to afford 3-substituted 4-enone moieties.

Abstract

Live animals have been produced recently from animal tissues preserved for decades at frozen temperatures with or without cryoprotectants. However, the tissues in these studies were cryopreserved within few hours of animal death to obtain culturable live cells as nuclear donors. How long the tissues can be left unfrozen after animal death, without losing the viability and potential to in vitro culture with comparable morphology and proliferative rate as the fresh tissues, is not completely understood. To understand this phenomenon, ear skin samples from individual sheep (n=3) were procured from slaughter plant and stored at 4 °C. After various intervals (2, 8, 24, 32, 48, and 56 h after slaughter), 2-3 mm(2) pieces (n=10) of skin samples were cultured for 12 d on two dishes (60 mm) for each sheep. Outgrowth of fibroblast-like cells was observed as early as day 4 of culture and was visible on dishes of all time points including 56 h by day 10. The number of outgrowing cells decreased with increasing time interval between animal slaughter and culture initiation. Secondary cultures were successfully established for all the time points. All cultures proliferated well and were apparently normal. Passage 2 cultures of 2 h and 56 h interval for one of the three sheep were compared for their growth pattern and proliferation rates. The population doubling time of 2 h and 56 h intervals was 33.12 and 34.8 h, respectively, and both the lines exhibited similar cell morphology and an "S"-shaped growth curve. These results suggest that skin tissues of sheep and perhaps other animal species with superior traits are effectively preserved at cellular level at least for 56 h at normal refrigerating conditions, without need of complicated cryopreservatives/cryotanks that are usually not available at small farms., (© The Society for In Vitro Biology 2011)

Abstract

The prevalence of antibody to hepatitis C virus (HCV) in hemodialysis (HD) patients is high and variable. One hundred and thirty nine patients undergoing maintenance HD at three different renal units in Jeddah, Kingdom of Saudi Arabia, were studied for prevalence of anti-HCV antibody. The overall prevalence in the group examined was 52.5% (73/139). There was a significant correlation between prevalence of anti-HCV and duration of HD; 53/ 74 (71.6%) in patients on HD for > 3 years as against 20/65 (30.8%) for patients on HD for < 3 years (P< 0.05). We were unable to demonstrate a correlation of anti-HCV positivity with history of blood transfusions, previous exposure to hepatitis-B virus, sex, age, or ethnic group. The very high prevalence of anti-HCV found in patients on maintenance HD and the positive correlation between anti-HCV reactivity and duration on dialysis suggest that factors within the dialysis unit might contribute to the spread of the virus.
