Unravelling taboos and cultural beliefs associated with hidden hunger among pregnant and breast-feeding women in Buyende district Eastern Uganda.

BACKGROUND: Food taboos and cultural beliefs among pregnant and breast-feeding women influence their food consumption patterns and hence the health of women and unborn children. Cognizant of their neglect in programs aimed to ameliorate hidden hunger among pregnant and breast-feeding women in Buyende and other resource-poor communities in sub-Saharan Africa, we opted for a study to unravel them to inform program design. METHODS: We documented food taboos and beliefs amongst pregnant and breast-feeding women from six sub-counties of Buyende district in Eastern Uganda. A mixed-methods approach was used, which was comprised of questionnaire interviews with 462 women, eight focus group discussions with 6-10 participants in each and a total of 15 key informant interviews. RESULTS: The present study revealed that 129 (27.9%) of the respondents practice food taboos and adhere to cultural beliefs related to their dietary habits during pregnancy and breast-feeding that are fuelling the prevalence of hidden hunger. The most tabooed foods during pregnancy were sugarcane (17.8%), fishes which included lung fish, catfish and the Lake Victoria sardine (Rastrineobola argentea) (15.2%), oranges (6.6%), pineapples (5.9%), eggs (3.3%), chicken (3.3%) and cassava, mangoes and Cleome gynandra (each at 3%). Most foods were avoided for reasons associated with pregnancy and labour complications and undesirable effects on the baby. Most women learnt of the taboos and beliefs from the elders, their own mother, grandparents or mother-in-law, but there was also knowledge transmission in social groups within the community. CONCLUSIONS: The taboos and cultural beliefs in the study area render pregnant and breast-feeding women prone to micronutrient deficiency since they are denied consumption of a diversity of nutritious foods. There is a need to educate such women about consumption of nutrient-rich foods like fish, eggs, fruits and vegetables in order to improve their health, that of the unborn and children being breast fed. Additionally, culturally appropriate nutrition education may be a good strategy to eliminate inappropriate food taboos and beliefs with negative impact on the health of pregnant and breast-feeding women.

Comparing Intraoperative Blood Loss in Cemented, Uncemented, and Hybrid Total Hip Replacement for Neck of Femur Fractures.

Background As the aging population increases, osteoporotic neck of femur fracture cases will continue to rise. Although hemiarthroplasty or half hip replacement is the treatment of choice in a majority of patients, a small but definite cohort of patients would need a total hip replacement. In these elderly patients who often have comorbidities, the use of cement to fix the prosthesis is often quoted as beneficial in view of perceived lower blood loss compared to uncemented fixation of the prosthesis. However, the cementation of the implant in itself has inherent problems. This study examined three modalities of fixation of a prosthesis for total hip replacement in the neck of femur fractures, namely, cemented, hybrid, and uncemented, and compared their relative intraoperative blood loss. Methodology This is a retrospective study with a follow-up of two years. Patients who presented to a level 1 trauma center in an inner city metropolitan with neck of femur fractures and were treated by total hip replacement were included in the study. Intraoperative blood loss was calculated using Nadler's formula. Results There was no statistical difference in intraoperative blood loss in either of the three groups of patients, namely, cemented, hybrid, or uncemented total hip replacement for neck of femur fractures. Conclusions Intraoperative blood loss should not influence the modality of prosthesis fixation for total hip replacement in neck of femur fractures.

Ecological distribution and genetic diversity of Azolla in Uganda.

BACKGROUND: Azolla is an important aquatic fern whose agronomic potential has not been fully exploited in Uganda. This study aimed at determining the genetic variation in the Azolla species existing in Uganda and the factors influencing their distribution in the different agro-ecological zones of Uganda. Molecular characterization was preferred in this study because of its efficiency in detecting variations among closely related species. RESULTS: Four species of Azolla were identified in Uganda with 100, 93.36, 99.22 and 99.39% sequence identities to the reference database sequences of; Azolla mexicana, Azolla microphylla, Azolla filiculoides and Azolla cristata, respectively. These different species were distributed in four out of the ten agro-ecological zones of Uganda which are situated in close vicinity to large water masses. The principal component analysis (PCA) results revealed that maximum rainfall and altitude significantly accounted for the variations in the distribution of Azolla with factor loadings of 0.921 and 0.922, respectively. CONCLUSION: Massive destruction coupled with prolonged disturbance of Azolla's habitat negatively affected its growth, survival and distribution in the country. Therefore, there is a need to develop standard methods that can preserve the various species of Azolla, so as to salvage them for future use, research and reference.

Bennett's Fracture Management: A Systematic Review of Literature.

Bennett's fracture is a relatively common fracture of the base of the thumb with no consensus on optimum management. Determining the optimal treatment method for Bennett's fractures remain a challenge and has been the subject of much debate. This systematic review aims to investigate present and past literature and determine the optimum treatment intervention for Bennett's fracture-dislocation. The primary outcome measure is post-traumatic arthritis, and the secondary outcome measures are reoperation, pain, infection, and nonunion. As per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of the literature was performed to evaluate patient demographics, clinical profile, management, and treatment outcomes. Two authors independently performed electronic searches of the Embase, Medical Literature Analysis and Retrieval System Online (MEDLINE), and Cochrane databases. Studies conducted between 1963 and 2021 with articles reporting Bennett's fracture management were included. The study was registered with PROSPERO (CRD42021295464). In the initial screening, 58 articles were identified, of which 13 articles met the criteria and were included in the final review, evaluating 558 patients. Out of these, 439 were managed by various surgical procedures, and 119 were treated by manipulation and plaster of Paris (POP) immobilization. Of the 13 studies considered, eight have a clear mention of post-traumatic osteoarthritis, with a total of 50 (9%) patients. Secondary outcomes included pain in 76 (13%) patients, infection in four patients, reoperation in 11 (2%) patients, and no nonunion. This review was conducted with the help of retrospective studies as there is no randomized controlled trial on the management of Bennett's fracture. Our primary outcome measure of post-traumatic arthritis in patients being treated by operative and conservative methods was mentioned in these studies. However, due to the sample size being small and the heterogenicity of these studies, the strength of these findings is low. Due to these shortfalls, this review study cannot recommend any single (or) particular treatment for all patients with Bennett's fracture.

Sandwich Enzyme-Linked Immunosorbent Assay for Quantification of Callose.

The existing methods of callose quantification include epifluorescence microscopy and fluorescence spectrophotometry of aniline blue-stained callose particles, immuno-fluorescence microscopy and indirect assessment of both callose synthase and ß-(1,3)-glucanase enzyme activities. Some of these methods are laborious, time consuming, not callose-specific, biased and require high technical skills. Here, we describe a method of callose quantification based on Sandwich Enzyme-Linked Immunosorbent Assay (S-ELISA). Tissue culture-derived banana plantlets were inoculated with Xanthomonas campestris pv. musacearum (Xcm) bacteria as a biotic stress factor inducing callose production. Banana leaf, pseudostem and corm tissue samples were collected at 14 days post-inoculation (dpi) for callose quantification. Callose levels were significantly different in banana tissues of Xcm-inoculated and control groups except in the pseudostems of both banana genotypes. The method described here could be applied for the quantification of callose in different plant species with satisfactory level of specificity to callose, and reproducibility. Additionally, the use of 96-well plate makes this method suitable for high throughput callose quantification studies with minimal sampling and analysis biases. We provide step-by-step detailed descriptions of the method.

Bacterial community and chemical profiles of oil-polluted sites in selected cities of Uganda: potential for developing a bacterial-based product for remediation of oil-polluted sites.

BACKGROUND: Oil spills are ranked among the greatest global challenges to humanity. In Uganda, owing to the forthcoming full-scale production of multi-billion barrels of oil, the country's oil pollution burden is anticipated to escalate, necessitating remediation. Due to the unsuitability of several oil clean-up technologies, the search for cost-effective and environmentally friendly remediation technologies is paramount. We thus carried out this study to examine the occurrence of metabolically active indigenous bacterial species and chemical characteristics of soils with a long history of oil pollution in Uganda that can be used in the development of a bacterial-based product for remediation of oil-polluted sites. RESULTS: Total hydrocarbon analysis of the soil samples revealed that the three most abundant hydrocarbons were pyrene, anthracene and phenanthrene that were significantly higher in oil-polluted sites than in the control sites. Using the BIOLOG EcoPlate™, the study revealed that bacterial species richness, bacterial diversity and bacterial activity (ANOVA, p < 0.05) significantly varied among the sites. Only bacterial activity showed significant variation across the three cities (ANOVA, p < 0.05). Additionally, the study revealed significant moderate positive correlation between the bacterial community profiles with Zn and organic contents while correlations between the bacterial community profiles and the hydrocarbons were largely moderate and positively correlated. CONCLUSIONS: This study revealed largely similar bacterial community profiles between the oil-polluted and control sites suggestive of the occurrence of metabolically active bacterial populations in both sites. The oil-polluted sites had higher petroleum hydrocarbon, heavy metal, nitrogen and phosphorus contents. Even though we observed similar bacterial community profiles between the oil polluted and control sites, the actual bacterial community composition may be different, owing to a higher exposure to petroleum hydrocarbons. However, the existence of oil degrading bacteria in unpolluted soils should not be overlooked. Thus, there is a need to ascertain the actual indigenous bacterial populations with potential to degrade hydrocarbons from both oil-polluted and unpolluted sites in Uganda to inform the design and development of a bacterial-based oil remediation product that could be used to manage the imminent pollution from oil exploration and increased utilization of petroleum products in Uganda.

Dislocation of Total Hip Replacement in Femoral Neck Fracture: Do Surgical Approach and Dual Mobility Implant Matter?

INTRODUCTION: Total hip replacement (THR) in the neck of femur fracture in the elderly is associated with a higher risk of dislocation compared to hemiarthroplasty of hip or total hip replacement in the native hip. There is uncertainty regarding combining surgical approach, femoral head size, and the usage of single bearing or dual mobility to reduce the risk of dislocation. This study looks into the bearing of the prosthesis for posterior or lateral surgical hip approach as well as their head size to give a stable hip to these vulnerable groups of patients. METHODS: Initial data were collected retrospectively from February 2017 till May 2019 from the electronic records database and clinical notes. Patients included in the study had a femoral neck fracture (age >60 years) who underwent a total hip replacement. Subsequent data were collected prospectively from June 2019 to July 2020. RESULTS: High rate of dislocation was found with posterior approach and single bearing prosthesis. However, if dual mobility prosthesis was used while using the posterior approach the dislocation rate was very low. Also, with lateral approach and single bearing prosthesis using large femoral head size, the dislocation rate was negligible. CONCLUSIONS: We recommend a dual mobility prosthesis for posterior approach THR and lateral approach with single-bearing hip replacement with large size femoral head. The dislocation rate is low using this principle irrespective of the surgical approach.

Regeneration of Fibula Following Distal Fibulectomy for Ankle Arthrodesis Following the Use of Calcium Sulphate Granules: A Case Series and Review of the Literature.

Regeneration of the fibula following partial fibulectomy is a common and well-reported phenomenon in children. However, there is limited literature on the regeneration of fibula in skeletally mature individuals. We report a case series of regeneration of the distal fibula following partial distal fibulectomy. In both these cases, calcium sulphate (Stimulan-Biocomposites, Keele, UK) antibiotic-loaded beads were used for local delivery of a high concentration of antibiotics. However, calcium sulphate worked as an osteoconductive agent and led to regeneration of the fibula. Regeneration of the fibula has its benefits and downside. Regeneration can be beneficial in patients in whom future arthroplasty is considered as total ankle replacement would not be possible in the absence of distal fibula. On the contrary, a regenerated fibula can be a source of ankle pain related to the syndesmotic joint. There is also a report of infection recurring in the regenerated fibula. Hence, while using calcium sulphate beads either as a spacer or as a vehicle for local delivery of antibiotics, the operating surgeon needs to be aware of the risk of regeneration of the fibula if the periosteum is preserved.

Triple osteotomy for the correction of severe hallux valgus deformity: Patient reported outcomes and radiological evaluation.

BACKGROUND: Symptomatic Hallux valgus can be treated with metatarsal osteotomy combined with proximal phalangeal osteotomy, however this might not be sufficient to treat severe HV deformities. METHODS: Fifteen feet in eleven female patients treated with double first metatarsal and proximal phalanx osteotomies without lateral release were prospectively studied and outcome measures including radiological angles and validated patient reported outcome scores collected. RESULTS: Mean radiological follow up was 15 months and PROMs data 17 months. Mean hallux valgus and intermetatarsal angles were corrected from 45 to 24.7° and 18.7 to 7.4° respectively. There was an eight degree recurrence of hallux valgus angle. There was no wound problems, non-unions or evidence of avascular necrosis. The EQ-5D descriptive index showed a non-statistically significant improvement. All three elements of the MOxFQ score showed a statistically significant improvement: Forefoot pain (59-26.8), Walking and Stability (49.9-29.6) and Social Interaction (56.4-33.1) CONCLUSION: Triple osteotomy, without a lateral soft tissue release, leads to good radiological and functional outcomes in those with severe hallux valgus deformity. Patients need to be warned of the recovery time and potential for future metalwork removal. The risk of early recurrence suggests that a lateral release should be included in order to maintain a long lasting correction.

Ipsilateral Intracapsular Hip Fracture 2 Years after Fixation of Extracapsular Fracture by Dynamic Hip Screw.

INTRODUCTION: Sustaining an intracapsular fracture in a hip which was previously fixed with dynamic hip screw for extracapsular fracture, is a very rarely reported occurrence. We present one such case in order to discuss the presentation and management of this fracture. We have also reviewed the literature and pooled the previously reported cases to look at potential cause & risk factors. CASE REPORT: A 92 year old female, presented with new onset hip pain following a trivial injury. Couple of years back, she had sustained an extracapsular fracture on same side which was treated by DHS fixation. Further investigations confirmed a de-novo fracture which was treated by removal of DHS and cemented bipolar hemiarthroplasty. CONCLUSION: This complication might not be as rare as earlier thought to be. All patients, especially elderly females who present with new onset hip pain following DHS fixation of their hip fracture previously must be evaluated for a de-novo intracapsular fracture. On confirmation of diagnosis, they can be treated by removal of dynamic hip screw and hemiarthroplasty as most of these are low demand elderly patients.

Giant solitary synovial osteochondromatosis of the elbow causing ulnar nerve neuropathy: a case report and review of literature.

INTRODUCTION: Giant or solitary osteochondroma is part of a rare disorder known as synovial osteochondromatosis. It forms part of a spectrum of disease characterized by metaplastic changes within the joint synovium that are eventually extruded as loose bodies. It has been suggested that solitary synovial osteochondroma forms as progression of synovial osteochondromatosis through a process of either coalescence of multiple smaller bodies or the growth of a dominant synovial osteochondroma. Previous studies have shown that it occurs as a late phase of the disease. We report a rare case of giant synovial osteochondromatosis at the elbow causing ulnar nerve neuropathy and mechanical symptoms which has not been previously reported in the literature. CASE REPORT: We report a case of a 56 year old Western European gentleman who presented with ulnar nerve neuropathy and swelling behind the elbow. The patient underwent MR imaging and subsequent biopsy that demonstrated synovial osteochondromatosis. Initially the patient declined surgery and opted for a watch and wait approach. Five years later he returned with worsening symptoms and underwent successful surgical resection of a giant solitary synovial osteochondroma. CONCLUSION: The unique outcome in our patient despite the long interval between presentation and surgical treatment resulted in early full resolution of symptoms within a short period. It may suggest an improved prognosis as compared to multiple synovial osteochondromatosis in terms of mechanical and neurological outcomes.
