Osteosarcoma to the left Heart

Primary and secondary tumors of the heart are rare. Myxoma is the commonest benign tumor. Of the malignant lesions metastatic heart tumors are more common although these have received little clinical attention. The right side of the heart is more commonly involved while the pericardium and/or myocardium more frequently involved than the endocardium. We present a case of metastatic osteosarcoma into the endocardium of the left atrium. The Annals of African Surgery, Volume 6, 201

Haematological predictors of poor outcome among COVID-19 patients admitted to an intensive care unit of a tertiary hospital in South Africa

BACKGROUND: Studies from Asia, Europe and the USA indicate that widely available haematological parameters could be used to determine the clinical severity of Coronavirus disease 2019 (COVID-19) and predict management outcome. There is limited data from Africa on their usefulness in patients admitted to Intensive Care Units (ICUs). We performed an evaluation of baseline haematological parameters as prognostic biomarkers in ICU COVID-19 patients. METHODS: Demographic, clinical and laboratory data were collected prospectively on patients with confirmed COVID-19, admitted to the adult ICU in a tertiary hospital in Cape Town, South Africa, between March 2020 and February 2021. Robust Poisson regression methods and receiver operating characteristic (ROC) curves were used to explore the association of haematological parameters with COVID-19 severity and mortality. RESULTS: A total of 490 patients (median age 54.1 years) were included, of whom 237 (48%) were female. The median duration of ICU stay was 6 days and 309/490 (63%) patients died. Raised neutrophil count and neutrophil/lymphocyte ratio (NLR) were associated with worse outcome. Independent risk factors associated with mortality were age (ARR 1.01, 95%CI 1.0–1.02; p = 0.002); female sex (ARR 1.23, 95%CI 1.05–1.42; p = 0.008) and D-dimer levels (ARR 1.01, 95%CI 1.002–1.03; p = 0.016). CONCLUSIONS: Our study showed that raised neutrophil count, NLR and D-dimer at the time of ICU admission were associated with higher mortality. Contrary to what has previously been reported, our study revealed females admitted to the ICU had a higher risk of mortality

Prognostic value of biochemical parameters among severe COVID-19 patients admitted to an intensive care unit of a tertiary hospital in South Africa

Background: Data on biochemical markers and their association with mortality rates in patients with severe coronavirus disease 2019 (COVID-19) admitted to intensive care units (ICUs) in sub-Saharan Africa are scarce. An evaluation of baseline routine biochemical parameters was performed in COVID-19 patients admitted to the ICU, in order to identify prognostic biomarkers. Methods: Demographic, clinical, and laboratory data were collected prospectively from patients with PCR-confirmed COVID-19 admitted to the adult ICU of a tertiary hospital in Cape Town, South Africa, between October 2020 and February 2021. Robust Poisson regression methods and the receiver operating characteristic (ROC) curve were used to explore the association of biochemical parameters with severity and mortality. Results: A total of 82 patients (median age 53.8 years, interquartile range 46.4–59.7 years) were enrolled, of whom 55 (67%) were female and 27 (33%) were male. The median duration of ICU stay was 10 days (interquartile range 5–14 days); 54/82 patients died (66% case fatality rate). Baseline lactate dehydrogenase (LDH) (adjusted relative risk 1.002, 95% confidence interval 1.0004–1.004; P = 0.016) and N-terminal pro B-type natriuretic peptide (NT-proBNP) (adjusted relative risk 1.0004, 95% confidence interval 1.0001–1.0007; P = 0.014) were both found to be independent risk factors of a poor prognosis, with optimal cut-off values of 449.5 U/l (sensitivity 100%, specificity 43%) and 551 pg/ml (sensitivity 49%, specificity 86%), respectively. Conclusions: LDH and NT-proBNP appear to be promising predictors of a poor prognosis in COVID-19 patients in the ICU. Studies with a larger sample size are required to confirm the validity of this combination of biomarkers

Task Sharing and Shifting to Provide Pathology Diagnostic Services: The Kenya Fine-Needle Aspiration Biopsy Cytology and Bone Marrow Aspiration and Trephine Biopsy Training Program

Purpose: Fine-needle aspiration biopsy (FNAB) cytology is a simple, inexpensive, and accurate diagnostic test for benign, infectious, and malignant lesions of the breast, thyroid, lymph nodes, and other organs. Similarly, bone marrow aspiration and trephine (BMAT) biopsy procedures are relatively simple and inexpensive techniques that are important for diagnosing and monitoring many hematologic diseases including leukemias and lymphomas. However, the scarcity of pathologists in Kenya limits patient access to these simple diagnostic tests. We describe a task sharing and shifting program that sought to improve the provision of FNABs and BMAT biopsies in tertiary public hospitals in Kenya. Methods: Between January 2016 and February 2017, we trained pathologists, pathology residents, and technologists from the University of Nairobi and Aga Khan University Hospital, Nairobi, in FNAB and BMAT biopsies, who in turn trained pathologists, medical officers (MO), clinical officers (CO), and technologists at five tertiary public hospitals. The program involved curriculum development, training workshops, the establishment of new and strengthening existing FNAB and BMAT biopsy clinics, interim site visits, audits, and stakeholder workshops. Results: Fifty-one medical personnel at the tertiary hospitals were trained. The FNAB numbers increased by 41% to 1,681, with 139 malignant diagnoses (7.1%). BMAT biopsy numbers increased by 268% to 140, with 34 malignant cases. Between 60% and 100% of the FNAB and BMAT biopsy procedures were performed by MO and CO over the project period. One new FNAB and two new BMAT biopsy clinics were established. Conclusion: This project demonstrates a successful model of task sharing and shifting from specialist pathologists to MO and CO that improved access to important FNAB and BMAT biopsy services in a low-resource setting

Evaluation of eLearning outcomes- experience from an online Psychotherapy education programme

SEPTIMUS is a one-year Europe-wide postgraduate theoretical course for psychotherapists and counselors provided entirely via the internet. It may be used as part of a training course, with face to face elements provided locally, or for continuing professional development. The course was developed at the University of Sheffield in collaboration with psychotherapy training institute partners in seven other European countries. Two studies involving 167 SEPTIMUS students and 60 comparable face-to-face students were undertaken. Study 1- Drop-out rates for the SEPTIMUS programme were found to be low, and comparison between those dropping out and those completing did not highlight any significant factors linked to distance learning. However, students cited Finance, Distance from training centre, Lack of practical experience, Family commitments and the Intensity of their working weeks as having been barriers to taking face-to-face learning courses in the past. Study 2- SEPTIMUS students (eLearners) were compared with students taking comparable attending (face-to-face) theoretical courses also being provided by partners in the project to psychotherapy trainees. Significant differences were found in Distance from training institute and Ability to visit training institute. SEPTIMUS students had higher levels of Computer ownership, Frequency of internet use and IT skills than attenders; these factors when examined in study 1 did not have an impact on the drop-out rate of eLearners. eLearning can overcome barriers to traditional learning in psychotherapy, particularly distance from a training centre, without loss of student satisfaction or student performance. Factors sometimes thought to be obstacles to eLearning, such as IT skills, were not found to be significant barriers, although may have affected recruitment. Certain aspects of eLearning, such as the tendency to facilitate self-disclosure, were found to be very beneficial particularly in the context of psychotherapy programmes
