Extent and pattern of symptom relief following surgical castration in patients with advanced prostate cancer treated at a tertiary referral hospital in Tanzania: a prospective cohort study

BackgroundAdvanced prostate cancer leads to many symptoms, notably bone pain and lower urinary tract symptoms (LUTs); however, the degree and duration of pain relief, changes in LUTs severity and underlying factors associated with the extent of symptom relief remain inadequately understood. Surgical castration has proven effective in relieving both bone pain and urinary symptoms for metastatic prostate cancer patients.ObjectiveTo determine the extent and pattern of symptom relief in advanced prostate cancer patients following surgical castration at Muhimbili National Hospital (MNH).MethodsWe conducted a prospective cohort study for a period of 6 months involving men with advanced Prostate cancer (PCa) undergoing surgical castration at MNH and followed them for 30 days. The international prostate symptoms score tool was used to assess changes in LUTs, and the pain rating scale was used for assessing changes in bone pain symptoms before and after surgery. Logistic regression model was used to determine factors associated with complete bone pain relief.ResultsA total of 210 participants with a mean age of 72.3 years were recruited. The LUTS score showed a decrease of 7.1 points after surgical castration (95% CI: 6.4 to 7.7, p < 0.001). The bone pain score showed an absolute decrease of 39.8% (95% CI: 34.7 to 44.9, p < 0.001) after surgical castration, with more than half of the patients (111, 52.9%) reporting bone pain relief within the first two weeks. Among the factors associated with greater pain relief were being in a marital union (aOR 2.73, 95% CI: 1.26 to 5.89, p < 0.011). Normal BMI was also linked to pain relief in bivariate analysis (OR 1.92, 95% CI: 1.03 to 3.61, p < 0.035). Additionally, patients with severe bone pain before surgical castration were more likely to achieve complete pain relief compared to those with mild or moderate pain (odds ratio 8.32, 95% CI: 3.63 to 19.1, p < 0.001).ConclusionSurgical castration improves both bone pain and lower urinary tract symptoms in patients with advanced prostate cancer. Notably, patients experiencing severe bone pain reported resolution of bone pain symptoms within the first and second weeks, respectively, indicating the prompt effectiveness of the surgery on these symptoms.

Outcomes of pediatric in-hospital cardiac arrest in the emergency department of a tertiary referral hospital in Tanzania: a retrospective cohort study

BackgroundCardiopulmonary resuscitation (CPR) is an emergency procedure performed to restore heart function to minimize anoxic injury to the brain following cardiac arrest.Despite the establishment of emergency department and training on Pediatric Advanced Life Support (PALS) at Muhimbili National Hospital (MNH) the outcomes of pediatric in-hospital cardiac arrest have not been documented. We ought to determine the outcomes and factors associated with 24-h survival after pediatric in-hospital cardiac arrests at MNH in Tanzania.MethodsWe conducted a retrospective study of all patients aged 1 month to 18 years who had in-hospital cardiac arrests (IHCA) prompting CPR in the Emergency Medicine Department (EMD) at MNH, Tanzania from January 2016 to December 2019. Data was collected from electronic medical record (Wellsoft) system using a standardized and pretested data collection form that recorded clinical baseline, pre-arrest, arrest, and post-arrest parameters. Bivariate and multivariable logistic regression analyses were performed to assess the influence of each factor on 24-h survival.ResultsA total of 11,951 critically ill patients were screened, and 257 (2.1%) had cardiac arrest at EMD. Among 136 patients enrolled, the median age was 1.5 years (interquartile range: 0.5–3 years) years, and the majority 108 (79.4%) aged ≤ 5 years, and 101 (74.3%) had been referred from peripheral hospitals. Overall stained return of spontaneous circulation was achieved in 70 (51.5%) patients, 24-h survival was attained in 43 (31.3%) of patients, and only 7 patients (5.2%) survived to hospital discharge. Factors independently associated with 24-h survival were CPR event during the day/evening (p = 0.033), duration of CPR ≤ 20 min (p = 0.000), reversible causes of cardiac arrest being identified (p = 0.001), and having assisted/mechanical ventilation after CPR (p = 0.002).ConclusionIn our cohort of children with cardiac arrest, survival to hospital discharge was only 5%. Factors associated with 24-h survival were CPR events during the daytime, short duration of CPR, recognition of reversible causes of cardiac arrest, and receiving mechanical ventilation. Future studies should explore the detection of decompensation, the quality of CPR, and post-cardiac arrest care on the outcomes of IHCA.

Xpert Breast Cancer STRAT4 Assay using fine-needle aspiration biopsy samples in a resource-constrained setting: a prospective diagnostic accuracy study

Use of fine-needle aspiration biopsy (FNAB) specimens on Xpert Breast Cancer STRAT4 Assay (STRAT4; Cepheid, Sunnyvale, CA, USA), a CE-marked in-vitro diagnostic medical device, could potentially increase access to breast cancer biomarker testing in resource-constrained settings. We aimed to assess the performance of a research use-only version of STRAT4 using FNAB specimens in Tanzania. In this prospective diagnostic accuracy study, patients aged 18 years or older with palpable breast masses presenting to the FNAB Clinic at Muhimbili National Hospital (Dar es Salaam, Tanzania) were recruited consecutively. Patients who were pregnant, lactating, or had a previous diagnosis of breast cancer were excluded. STRAT4 testing was performed on off-label FNAB samples using four protocols: the 1 × protocol (using the standard lysate method) on FNAB smears (1 × FNAB), quick lysis and Maui protocols (both on FNAB smears), and the 1 × protocol on formalin-fixed paraffin-embedded (FFPE) cell block material (1 × cell block). For 1 × FNAB and 1 × cell block, tissue was processed using FFPE lysis reagent, incubated at 80°C with proteinase K, and followed by addition of 95% or higher ethanol. Quick lysis was processed using FFPE lysis reagent and 95% or higher ethanol, whereas Maui was processed using a proprietary research-use only lysis reagent. The primary outcomes were overall concordance, sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) of STRAT4 as compared with immunohistochemistry or immunohistochemistry plus fluorescence in-situ hybridisation performed on cell blocks using clinically validated protocols in a Clinical Laboratory Improvement Amendments-accredited laboratory at the University of California, San Francisco (San Francisco, CA, USA). Between Nov 29, 2017, and Dec 17, 2020, 208 patients were enrolled. Of 208 cases, 51 (25%) were excluded from analysis because of insufficient tissue in the cell block or absent cell blocks, leaving 157 participants (all female) for analysis. For oestrogen receptor, 1 × FNAB had the best performance, with an overall concordance of 95% (95% CI 90-100), sensitivity of 94% (85-100), specificity of 97% (90-100), and AUC of 0·96 (0·81-1·00). For progesterone receptor, 1 × cell block had the best overall performance (overall concordance 89% [95% CI 84-95], sensitivity 91% [82-99], and specificity 89% [81-97], with an AUC of 0·93 [0·89-0·99]) and 1 × FNAB performed the best among the smear protocols, with a concordance of 84% (95% CI 74-93), sensitivity of 63% (43-82), specificity of 97% (92-100), and AUC of 0·91 (0·72-0·97). For HER2, Maui had the highest agreement, with an overall concordance of 93% (95% CI 89-98), sensitivity of 96% (88-100), specificity of 92% (87-98), and AUC of 0·95 (0·98-1·00). For Ki67, Maui had the best performance of smear protocols, with a concordance of 73% (95% CI 64-82), sensitivity of 70% (58-81), specificity of 81% (66-96), and AUC of 0·80 (0·54-0·82). Processing FNAB samples with STRAT4 is feasible in Tanzania, and performance for the oestrogen receptor is robust. Further optimisation of STRAT4 for FNAB has the potential to improve timely access to breast cancer diagnostics in resource-constrained settings.

Clinical profile and outcome of kidney transplantation at Muhimbili National Hospital, Tanzania

BackgroundKidney transplantation is the definitive treatment option for chronic kidney failure, offering improved quality of life and extended survival. Access to kidney transplantation is limited in the Sub-Saharan Africa (SSA) region, with only a few countries with established services. Tanzania started its program five years ago, for the sustainability of the program it is important to understand the outcome. Therefore, this study was conducted to determine the clinical outcomes and survival rates of kidney transplant recipients at Muhimbili National Hospital in Tanzania, in the absence of a national transplant registry, since the inception of the program.MethodsThis was a retrospective study conducted among kidney transplant recipients from live donors at Muhimbili National Hospital (MNH) between November 2017 and February 2022. Analyses were performed to assess baseline characteristics, post-transplant complications, and patient and graft survival.ResultsIn our study of 68 kidney transplant recipients, the majority of recipients were male (63.2%) with a mean age of 45.8 years and under medical insurance (88.2%). The predominant cause of CKD was hypertension (58.2%) with recipients undergoing dialysis for a mean duration of 14.4 months, and basiliximab being the most commonly used induction medication (57.3%). The majority of donors were males (64.7%) and had first-degree relationships with recipients (76.5%). Haploid HLA mismatch was observed in 36.8% of cases. One-year patient and graft survival rates were 91.2% and 96.7%, respectively, with infection being the primary cause of death (n = 5), and more than half of deceased patients died with a functioning graft (n = 4).ConclusionOur study underscores favorable one-year patient and graft outcomes among kidney transplant recipients at Muhimbili National Hospital, Tanzania. However, challenges persist, notably with infections posing ongoing difficulties for this cohort.

Assessing the accuracy of the revised Cardiac Risk Index compared to the American Society of Anaesthesiologists physical status classification in predicting Pulmonary and Cardiac complications among non-cardiothoracic surgery patients at Muhimbili National Hospital: a prospective cohort study

BackgroundThe Revised Cardiac Risk Index (RCRI) and the American Society of Anaesthesiologists (ASA-PS) classification system are two commonly used tools for preoperative risk assessment. This study aimed to assess the accuracy of RCRI compared to the ASA-PS classification system in preoperative risk assessment for pulmonary and cardiac problems among non-cardiothoracic surgery patients admitted at Muhimbili National Hospital (MNH).MethodsThis was a prospective cohort study design conducted from August 2022 to April 2023 among 184 patients of 18 years and above admitted at MNH for elective non-cardiothoracic surgery. Data Analysis was conducted using STATA software version 16. Means and standard deviations were used to summarize continuous data. Frequencies and percentages were used to summarize categorical data. The logistic regression and ROC curve analysis were used to determine the correlation between variables.ResultsThe majority of patients (43.3%) had an RCRI score of 1 point, and 39.9% were classified as ASA class 1. Patients in ASA classes 3 and 4 had higher odds of developing cardiac and pulmonary complications (AUC = 0.75 and 0.77, respectively). Patients with an RCRI score of 2 or ≥ 3 points were also more likely to experience cardiac and pulmonary complications (AUC = 0.73 and 0.72, respectively). There was no significant difference in the predictive ability of the two tools. Both RCRI and ASA-PS classification systems were equally effective in predicting these complications.ConclusionBoth the RCRI and the ASA-PS classification system demonstrated good predictive ability for cardiac and pulmonary complications among patients undergoing non-cardiothoracic surgery.

The diagnostic accuracy of triphasic abdominal CT in detecting esophageal varices

BackgroundIn Tanzania, triphasic abdominal Computed Tomography (CT) is a more accessible and non-invasive alternative for diagnosing esophageal varices, though its accuracy has not been thoroughly evaluated, therefore this study aimed to determine the diagnostic accuracy of triphasic abdominal CT in detecting esophageal varices using esophagogastroduodenoscopy (OGD) as the gold standard among patients with upper gastrointestinal bleeding at Muhimbili National Hospital (MNH).MethodsThis cross-sectional study was conducted at MNH from January 2021 to May 2023. We sampled upper gastrointestinal bleeding patients who underwent both OGD and triphasic abdominal CT using non-probability consecutive sampling. The sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and accuracy of triphasic abdominal CT were assessed against OGD findings.ResultsIn a study of 200 participants, esophageal varices were detected in 54% by OGD and 53.5% by CT. We observed 105 true positives, 2 false positives, 90 true negatives, and 3 false negatives. Triphasic abdominal CT demonstrated a sensitivity of 97.2%, specificity of 97.8%, PPV of 98.1%, NPV of 96.8%, and an accuracy of 97.5%. Extraluminal findings included portal venous thrombosis in (22%), splenic collateral (51.5%), ascites (32%), hepatocellular carcinoma (13%), and periportal fibrosis (32%).ConclusionTriphasic abdominal Computed Tomography can be used as a reliable and non-invasive alternative modality for diagnosing and screening esophageal varices in resource-limited settings.

High-risk human papillomavirus genotyping in cervical cancers in Tanzania

BackgroundHigh-risk human papillomavirus (hrHPV) infection causes almost all cervical cancer. Women living with human immunodeficiency virus (Women living with HIV: WLWHIV) are at a six-fold increased risk of developing cervical cancer. This study assessed hrHPV types in cervical cancer by HIV status and histologic subtypes at Muhimbili National Hospital (MNH) in Tanzania.MethodsThis cross-sectional study used formalin-fixed paraffin-embedded (FFPE) archived tissue blocks of cervical carcinomas diagnosed in the Department of Anatomical Pathology at MNH from January to December 2020. Tissue sections were tested for 15 HPV genotypes (16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, and 68) using the Ampfire assay. The distribution of HPV genotypes was assessed and compared by HIV status and histologic subtypes.ResultsThe mean age ± standard deviation (N = 227, with valid HPV results) was 55 ± 12.9 years, 28.6% (n = 65) were WLWHIV, and squamous cell carcinoma (SCC) was the most common histologic subtype (91.2%). Most cervical carcinomas (81.1%, n = 184) tested positive for hrHPV with HPV16 (44.1%), HPV18 (15.9%), HPV35 (8.4%) and HPV45 (5.7%) being the most common HPV types. hrHPV was higher among older women with 64.5%, 85.1% and 81.3% among 30–40, 41–60 and ≥ 61-year-old women, respectively (p = 0.033). HPV16 was more commonly detected in SCC (47.8%) than in adenocarcinomas (5%) (p < 0.0001). There was no difference in hrHPV positivity by HIV status.ConclusionsWe found a high proportion of hrHPV among cervical carcinomas diagnosed in Tanzania. Rolling out HPV vaccines that target more hrHPV types than HPV16/18, especially HPV35 and HPV45, could optimize protection against cervical cancer in Tanzania.

Prevalence and patterns of multidrug-resistant bacteria isolated from sputum samples of patients with bacterial pneumonia at a tertiary hospital in Tanzania

BackgroundAntimicrobial resistance affects the treatment of several bacterial infections, including pneumonia. This subsequently increased the morbidity and mortality rates of patients with bacterial pneumonia, especially in resource-limited settings. In this study, we aimed to determine the patterns of multidrug-resistant (MDR) bacteria isolated from the sputum samples of patients with bacterial pneumonia attending a tertiary hospital in Tanzania.MethodologyA retrospective cross-sectional study was conducted. It involved reviewing the laboratory sputum data in the laboratory information system at Muhimbili National Hospital in Tanzania. The sputum samples were previously processed using standard methods (culture, Gram staining, and biochemical tests) to isolate and identify the bacteria. At the same time, antibiogram profiles were determined using antimicrobial susceptibility tests. Bacterial isolates that expressed MDR patterns were identified. Demographic information was collected from patients' medical records. We used the chi-square test to determine factors associated with MDR. A p-value < 0.05 was considered significant.ResultsWe retrieved and analysed 169 laboratory records of patients with a provisional clinical diagnosis of bacterial pneumonia confirmed in the microbiology laboratory. Nearly 98% of the records were from adult patients. The patients’ mean age was 48.3 years and 17.3 standard deviations. About 84% of the isolated bacteria were Gram-negative; the most predominant was Klebsiella pneumoniae (59/142; 41.5%). The predominant Gram-positive bacteria was Staphylococcus aureus (25/27; 92.6%). Furthermore, 80 out of 169 (47.3%) bacteria were MDR; Klebsiella pneumoniae (32.5%) was predominant. In addition, 50% of Staphylococcus aureus was methicillin resistance. MDR bacterial pneumonia was highly observed in patients admitted to the Intensive Care Unit (p < 0.05).ConclusionsAlthough our study was limited by variations in the number of bacterial isolates subjected to the same antibiotic drugs and a lack of information on risk factors such as occupation, smoking history, and marital status, we observed that a high proportion of bacterial pneumonia is caused by MDR Gram-negative bacteria in our local setting. These results inform the need to improve infection prevention control measures in hospitals to reduce the burden of MDR bacteria in our settings and other similar resource-limited settings.

Enormous ectopic liver tissue at the gastrohepatic ligament: a rare entity at Muhimbili National Hospital, Tanzania

BackgroundEctopic liver tissue (ELT) is a developmental abnormality in which liver tissue develops at an extrahepatic site without connection to the true liver. It is a rare entity with an incidence of 0.24–0.56% according to data described in laparoscopic or autopsy studies. The detailed mechanism behind the development of ELT is poorly understood. ELT predominantly has an asymptomatic nature, even by means of radiological studies the diagnosis of ELT without surgery or autopsy is difficult. ELT has been reported mostly to be found frequently on the gallbladder and rarely on the gastrohepatic ligament. ELT has increased the potential risk of HCC which makes the resection crucial. Due to its variations anatomically, ELT recognition should gain clinical importance and surgeons need to be aware of these possible disparities.Case presentation.We present a 59-year-old female from Western Tanzania was presented to us with 2-month history of painless upper abdominal swelling. An abdominal CT scan was performed, and it revealed a large mass located at the gastrohepatic region with blood supply mainly from the left hepatic artery and omentum. Technically difficult excision of 17 × 12 cm tumor at gastrohepatic ligament was performed, with uneventful recovery. Post-operative histology results revealed capsulated hepatic parenchyma without the biliary components and limited sinusoids with tissue degeneration. To date, no complications happened during follow-up for one year.ConclusionELT is a rare entity with a predominantly asymptomatic nature. Preoperatively diagnosis is difficult even with images. It has anatomical variation and is hardly found along the gastrohepatic ligament. ELT has increased the potential risk of HCC which makes the resection crucial. Increased awareness of this congenital anomaly may result in increased detection rates.

Practice of Low Flow Anaesthesia and Volatile Agents Choices among Anaesthesia Providers at Muhimbili National Hospital and Muhimbili Orthopaedic Institute

With the availability of modern workstations and heightened awareness of the Health services cost and environmental effects of waste anaesthesia gases, anaesthesia providers worldwide are practicing low flow anaesthesia. In most developing countries Low Flow Anaesthesia is still underutilized due to lack of monitoring equipments and sufficient knowledge. Tanzania appears to have a paucity of studies on the prevailing practice pattern of fresh gas flow. Objective; The study aimed at assessing the practice of low flow anaesthesia and volatile agents choices among anaesthesia providers at Muhimbili national hospital and Muhimbili orthopaedic institute. Methods: A descriptive cross-sectional study was carried out for a period of 8 months involving 158 anaesthesia providers. A Structured questionnaire was used to collect data which included demographic, practice setting of Low Flow Anaesthesia, Workstations, scavenging, monitoring equipments, Volatile agents routinely used and preferred Agent. Data were analysed using the IBM Statistical package for social science’s version 23.0. Result: Prevalence of Low flow anaesthesia was 27.2%, however, only 6% used the fresh gas flow of 1l/min – 500mls/min. All anaesthesia providers had workstations and only 2.3% displayed Minimum Alveolar concentration (MAC), 79.1% worked in theatre with functioning scavenging systems, 55.8% used capnography, 6.9% monitored inspiratory Oxygen and none of anaesthesia providers used Bispectral and Agent Analyzers. Isoflurane was the most routinely used inhalational agents (100%) followed by Sevoflurane (69%), then Halothane (32%). Desflurane still not available in these hospitals. Conclusion: Low flow anaesthesia is seldom practiced in our locality despite having strong evidence of attractive advantages in medical practice and ergonomics.

Assessment of Energy Consumption Patterns and Validation of Predictive Equations among ICU Patients at Muhimbili National Hospital in Dar es Salaam, Tanzania

Background: Nutritional support in critically-ill patients is one of the most important parameters guarding the prognosis and influencing morbidity and mortality in these patients, owing to that fact, accurate measurement of the resting energy expenditure using Indirect calorimetry is recommended by guidelines as a gold standard. But due to lack of resources and other technicalities predictive equations are conveniently used as surrogates. Aims: This study was intended to examine the extent of malnutrition, poor nutrition support practices and to validate the common used predictive equations in critically-ill patients in our setting. Methodology: A hospital-based descriptive cross-sectional study was conducted on consecutively sampled 110 mechanically ventilated ICU patients at Muhimbili National Hospital Mloganzila. Anthropometric measurements, duration of stay in ICU, Temperature and Minute Volumes were recorded so as to estimate resting energy expenditure, REE from different predictive equations. Using Indirect Calorimetry Module patient’s REE was measured and recorded then a statistical data analyzed using SPSS software version 23. Results: The prevalence of poor nutritional support was 69%; underfeeding and overfeeding were observed in 41.8% and 27.3% of all participants respectively. Prevalence of malnutrition was 51.8%; underweight and overweight were found to be in 29.1% and 22.7% of all participants respectively. The accuracy of predictive equation in ±10% difference was 30%, 45.5%, 46.4% and 68.2% in HB, MSJ, ESPEN and PENN respectively. Conclusion and Recommendation: Malnutrition and Poor Nutritional support are common problems in ICU. Predictive equations have poor accuracy and validity in comparison to indirect calorimetry. Penn State Equation was the most accurate and with the highest agreement with IC.
