Intestinal intussusception in an adult caused by helminthic parasitosis

Intestinal intussusception is an uncommon acute condition in adults and is most commonly caused by an intestinal tumor mass. Helminthic parasitosis is a widespread infection in Africa, and the load of worms is often high in individuals living in areas with inadequate sanitation. We report a case of intestinal obstruction caused by Ascaris lumbricoides infection, which was complicated by ileo-caecal intussusception and required surgical treatment in a 40-year-old Ugandan woman. This case reinforces the importance of anthelminthic prophylaxis in African rural areas

The prevalence and antibiotics susceptibility pattern of Neisseria gonorrhoeae in patients attending OPD clinics at St. Mary?s Hospital Lacor Uganda

Introduction. Gonorrhea is one of the most common sexually transmitted infections (STIs) in developing countries, and the emergence of resistance to antimicrobial agents in Neisseria gon- orrhoeae is a major obstacle in the control of gonorrhoea. Peri- odical determination of the prevalence and monitoring of antimi- crobial susceptibility of N. gonorrhoeae is essential for the early detection of emergence of drug resistance. Methods. A total of 640 consecutive patients who attended the Outpatient Department (OPD) Clinics at St. Mary?s Hospital Lacor between Jan 2007-Dec 2011, with gonococcal urethri- tis symptoms and whose urethral swabs and high vagina swabs (HVS) were cultured, were involved in the study. Two hundred and fifty six (256) patients had positive pus swab culture, of which 151 (23.6%) showed growth of Neisseria gonorrhoeae. All the isolates were tested for antimicrobial susceptibility using the Kirby Bauer-Disc diffusion techniques. Results. Gonococcal isolates showed rapid decrease in suscepti- bility to the antimicrobials especially to Ampicillin, Tetracycline and Erythomycin, Ciprofloxacin, and intermediate to chloram- phenicol, however, Gentamicin and cefotaxime have remained as a single dose sensitive treatment for Neisseria gonorrhoeae. Sen- sitization on drug use and adopting preventive measures and con- tinuous education on safer sexual behavior through health care authorities would lead to reduction in the prevalence of Neisseria gonorrhoeae and resistance to antimicrobial. Discussion. Gonorrhea is one of the most common sexually trans- mitted infections (STIs) in developing countries, and the emer- gence of resistance to antimicrobial agents in Neisseria gonor- rhoeae is a major obstacle in the control of gonorrhea. Periodi- cal monitoring of antimicrobial susceptibility of N. gonorrhea is essential for the early detection of emergence of drug resistance

The meaning of caring for patients with cancer among traditional medicine practitioners in Uganda: A grounded theory approach

Traditional medicine practitioners (TMPs) are a critical part of healthcare systems in many sub-Saharan African countries and play vital roles in caring for patients with cancer. Despite some progress in describing TMPs’ caring experiences in abstract terms, literature about practice models in Africa remains limited. This study aimed to develop a substantive theory to clarify the care provided by TMPs to patients with cancer in Uganda. This study adhered to the principal features of the modified Straussian grounded theory design. Participants were 18 TMPs caring for patients with cancer from 10 districts in Uganda, selected by purposive and theoretical sampling methods. Researcher-administered in-depth interviews were conducted, along with three focus group discussions. Data were analyzed using constant comparative analysis. The core category that represented TMPs’ meaning of caring for patients with cancer was “Restoring patients’ hope in life through individualizing care.” TMPs restored patients’ hope through five main processes: 1) ensuring continuity in the predecessors’ role; 2) having full knowledge of a patient’s cancer disease; 3) restoring hope in life; 4) customizing or individualizing care, and 5) improving the patient’s condition/health. Despite practice challenges, the substantive theory suggests that TMPs restore hope for patients with cancer in a culturally sensitive manner, which may partly explain why patients with cancer continue to seek their services. The findings of this study may guide research, education, and public health policy to advance traditional medicine in sub-Saharan Africa

Phenotype is sustained during hospital readmissions following treatment for complicated severe malnutrition among Kenyan children : a retrospective cohort study

Hospital readmission is common among children with complicated severe acute malnutrition (cSAM) but not well-characterised. Two distinct cSAM phenotypes, marasmus and kwashiorkor, exist, but their pathophysiology and whether the same phenotype persists at relapse are unclear. We aimed to test the association between cSAM phenotype at index admission and readmission following recovery. We performed secondary data analysis from a multicentre randomised trial in Kenya with 1-year active follow-up. The main outcome was cSAM phenotype upon hospital readmission. Among 1,704 HIV-negative children with cSAM discharged in the trial, 177 children contributed a total of 246 readmissions with cSAM. cSAM readmission was associated with age<12 months (p = .005), but not site, sex, season, nor cSAM phenotype. Of these, 42 children contributed 44 readmissions with cSAM that occurred after a monthly visit when SAM was confirmed absent (cSAM relapse). cSAM phenotype was sustained during cSAM relapse. The adjusted odds ratio for presenting with kwashiorkor during readmission after kwashiorkor at index admission was 39.3 [95% confidence interval (95% CI) [2.69, 1,326]; p = .01); and for presenting with marasmus during readmission after kwashiorkor at index admission was 0.02 (95% CI [0.001, 0.037]; p = .01). To validate this finding, we examined readmissions to Kilifi County Hospital, Kenya occurring at least 2 months after an admission with cSAM. Among 2,412 children with cSAM discharged alive, there were 206 readmissions with cSAM. Their phenotype at readmission was significantly influenced by their phenotype at index admission (p < .001). This is the first report describing the phenotype and rate of cSAM recurrence

Prevalence of the Use of Herbal Medicines among Patients with Cancer: A Systematic Review and Meta-Analysis

Background: Although herbal medicines are used by patients with cancer in multiple oncology care settings, the magnitude of herbal medicine use in this context remains unclear. )e purpose of this review was to establish the prevalence of herbal medicine use among patients with cancer, across various geographical settings and patient characteristics (age and gender categories). Methods: Electronic databases that were searched for data published, from January 2000 to January 2020, were Medline (PubMed), Google Scholar, Embase, and African Index Medicus. Eligible studies reporting prevalence estimates of herbal medicine use amongst cancer patients were pooled using random-effects meta-analyses. Studies were grouped by World Bank region and income groups. Subgroup and meta regression analyses were performed to explore source of heterogeneity. Results: In total, 155 studies with data for 809,065 participants (53.95% female) met the inclusion criteria. Overall, the pooled prevalence of the use of herbal medicine among patients with cancer was 22% (95% confidence interval (CI): 18%–25%), with the highest prevalence estimates for Africa (40%, 95% CI: 23%–58%) and Asia (28%, 95% CI: 21%–35%). )e pooled prevalence estimate was higher across low- and middle-income countries (32%, 95% CI: 23%–42%) and lower across high-income countries (17%, 95% CI: 14%–21%). Higher pooled prevalence estimates were found for adult patients with cancer (22%, 95% CI: 19%–26%) compared with children with cancer (18%, 95% CI: 11%–27%) and for female patients (27%, 95% CI: 19%–35%) compared with males (17%, 95% CI: 1%–47%). Conclusion: Herbal medicine is used by a large percentage of patients with cancer use. The findings of this review highlight the need for herbal medicine to be integrated in cancer care

Ethnobotanical survey of medicinal plants used in the management of cancer in Uganda

Introduction: Patients with cancer in Africa embrace the use of herbal medicine more than anywhere else in the world. This study identified and documented medicinal plant species used to manage cancer in ten (10) districts of Uganda. Methods: An ethnobotanical survey was conducted between October 2021 and January 2022. In total, 18 (out of 55) traditional medicine practitioners (TMPs) having more than 10 years of experience in managing patients with cancer were interviewed using a semi-structured questionnaire. Data were analysed using descriptive statistics. The Relative frequency of citation (RFC) and Family importance value (FIV) indices were also computed. Results: We identified 121 plant species, belonging to 55 families, with the most common families being the Fabaceae (20 species, FIV = 0.119), Asteraceae (13 species, FIV = 0.131), and Euphorbiaceae (eight species, FIV = 0.079). The plant parts most commonly used were leaves (39.3%) and roots (12.9%). The most frequently cited plants were: Hoslundia opposita Vahl (RFC = 0.44), followed by Aspilia africana (Pers.) C.D. Adams (RFC = 0.33), Spathodea nilotica Seem (RFC = 0.33), Annona muricata L. (RFC = 0.33, Prunus africana (Hook.f.) Kalkman (RFC = 0.28), Acacia hockii De Wild (RFC = 0.28), Bidens pilosa L. (RFC = 0.28), and Carica papaya L (RFC = 0.22). The most common method of plant preparation and administration was the decoction (69.2%) and oral (86.7%) route, respectively. Conclusions: Although most plants used by TMPs have the potential to generate leads for chemo-preventive cancer medicines, they remain unexplored. This study provides a lead to explore the potential of traditionally used plants for the management of cancer through pre-clinical and clinical research

Epstein-Barr virus and malaria upregulate AID and APOBEC3 enzymes, but only AID seems to play a major mutagenic role in Burkitt lymphoma

Endemic Burkitt lymphoma (eBL) is characterized by an oncogenic IGH/c-MYC translocation and Epstein-Barr virus (EBV) positivity, and is epidemiologically linked to Plasmodium falciparum malaria. Both EBV and malaria are thought to contribute to eBL by inducing the expression of activation-induced cytidine deaminase (AID), an enzyme involved in the IGH/c-MYC translocation. AID/apolipoprotein B mRNA editing catalytic polypeptide-like (AID/APOBEC) family enzymes have recently emerged as potent mutagenic sources in a variety of cancers, but apart from AID, their involvement in eBL and their regulation by EBV and P. falciparum is unknown. Here, we show that upon inoculation with EBV, human B cells strongly upregulate the expression of enzymatically active APOBEC3B and APOBEC3G. In addition, we found significantly increased levels of APOBEC3A in B cells of malaria patients, which correlated with parasite load. Interestingly, despite the fact that APOBEC3A, APOBEC3B, and APOBEC3G caused c-MYC mutations when overexpressed in HEK293T cells, a mutational enrichment in eBL tumors was only detected in AID motifs. This suggests that even though the EBV- and P. falciparum-directed immune response triggers the expression and activity of several AID/APOBEC members, only the upregulation of AID has oncogenic consequences, while the induction of the APOBEC3 subfamily may primarily have immunoprotective functions

The decline of water hyacinth on Lake Victoria was due to biological control by Neochetina spp

There has been some debate recently about the cause of the decline of water hyacinth on Lake Victoria. While much of this evidence points to classical biological control as the major factor, the El Niño associated weather pattern of the last quarter of 1997 and the first half of 1998 has confused the issue. We argue first that the reductions in water hyacinth on Lake Victoria were ultimately caused by the widespread and significant damage to plants by Neochetina spp., although this process was increased by the stormy weather associated with the El Niño event; second that increased waves and current on Lake Victoria caused by El Niño redistributed water hyacinth plants around the lake; and third that a major lake-wide resurgence of water hyacinth plants on Lake Victoria has not occurred and will not occur unless the weevil populations are disrupted. We conclude that the population crash of water hyacinth on Lake Victoria would not have occurred in the absence of the weevils, but that it may have been hastened by stormy weather associated with the El Niño event

Dosing of Ceftriaxone and Metronidazole for Children With Severe Acute Malnutrition

Infants and young children with severe acute malnutrition (SAM) are treated with empiric broad‐spectrum antimicrobials. Parenteral ceftriaxone is currently a second‐line agent for invasive infection. Oral metronidazole principally targets small intestinal bacterial overgrowth. Children with SAM may have altered drug absorption, distribution, metabolism, and elimination. Population pharmacokinetics of ceftriaxone and metronidazole were studied, with the aim of recommending optimal dosing. Eighty‐one patients with SAM (aged 2–45 months) provided 234 postdose pharmacokinetic samples for total ceftriaxone, metronidazole, and hydroxymetronidazole. Ceftriaxone protein binding was also measured in 190 of these samples. A three‐compartment model adequately described free ceftriaxone, with a Michaelis–Menten model for concentration and albumin‐dependent protein binding. A one‐compartment model was used for both metronidazole and hydroxymetronidazole, with only 1% of hydroxymetronidazole predicted to be formed during first‐pass. Simulations showed 80 mg/kg once daily of ceftriaxone and 12.5 mg/kg twice daily of metronidazole were sufficient to reach therapeutic targets
