BIOMECHANICAL ANALYSIS OF POLYESTER SILICONE-COATED ARTIFICIAL TENDON AND ACCOMPANYING SUTURE ANCHORS

The incidence of Achilles tendon rupture has increased from 11 to 37 per 100,000 population in recent decades with these ruptures causing pain, swelling and disability in the patient. Critically sized tendon gaps, which are too large to heal spontaneously, are currently treated with tendon grafts, but the use of grafts have some challenges such as donor site morbidity, risk of disease transmission, and potential mismatches in length and size. An artificial tendon can address these challenges and may be customizable for each patient. If the whole tendon is replaced with an artificial tendon, suture anchors are one option for attaching the artificial tendon to bone. The mechanical characteristics of the suture anchor used in musculoskeletal reconstructions (e.g. to attach an artificial tendon) can limit the strength of the attachment and lead to premature failure. The objectives of this dissertation were to (1) investigate the reasons for in vivo failures of suture anchors used to attach artificial Achilles tendons in a rabbit model, (2) quantify the maximum failure load of suture anchors identified as suitable for attaching artificial tendons in rabbit, and (3) evaluate the effects of artificial Achilles tendon on hindlimb biomechanics and muscle morphology in rabbits. We observed that neither suture size (1 or 5) nor time of implantation (delayed or immediate) was a causative factor for the failures. In addition, suture anchors with raised eyelets decreased suture strength compared to those with embedded eyelets, irrespective of loading condition. We also found that artificial Achilles tendon preserved average ground contact area, peak vertical force and vertical impulse. It improved muscle cross-sectional area (CSA) and could potentially mitigate loss of muscle mass and length. These outcomes can help surgeons improve their choice of anchors for soft tissue reconstructions, reduce the risk of revision surgeries which are painful and costly to patients, and address the challenges associated with the use of tendon grafts for treating tendon ruptures

A comparative study of glycopyrrolate and dexamethasone in the control of postoperative nausea and vomiting after intrathecal fentanyl and bupivacaine for caesarean section

Background: Postoperative nausea and vomiting (PONV) is an undesirable outcome that parturient who undergo caesarean section experience. We compare the efficacies of IV glycopyrrolate and IV dexamethasone as prophyaxis against PONV in these paturient.Methods: This was a prospective, randomized, double blind placebo-controlled study of seventy six (76) ASA II patients aged 18-40 years who underwent elective caesarean section under spinal anaesthesia. Patients were randomly allocated to three groups, group G (glycopyrrolate): n=26, group D (dexamethasone): n=25 and group C (control; normal saline): n=25. Data collection was with the aid of a proforma which included the biophysical profile, Belville scoring scale for PONV, Likert scale was used for patient satisfaction and side effects were also documented. The data were analyzed using SPSS version 17 and presented in tables and figures.Results: The demographic characteristics and mallampati scores of patients in all 3 groups were similar. The results showed that the incidence of PONV in group D was 8%, in group G 19.2% and in group C 32% (p= 0.048, OR= 0.185, 95% C.I for OR= 0.035 – 0.983). All patients expressed satisfaction in the care they received as assessed using the Likert scale and only patients who received IV glycopyrrolate experienced side effects in the form of dryness of the mouth. There were no side effects reported in patients who received IV dexamethasone.Conclusions: The study demonstrated that IV dexamethasone 8mg was more effective in controlling PONV after intrathecal fentanyl and bupivacaine for caesarean section when compared to 0.2 mg IV glycopyrrolate

Mycobacterium tuberculosisis the causative agent of tuberculosis in the southern ecological zones of Cameroon, as shown by genetic analysis

BACKGROUND: Tuberculosis (TB) is a major cause of mortality and suffering worldwide, with over 95% of TB deaths occurring in low- and middle-income countries. In recent years, molecular typing methods have been widely used in epidemiological studies to aid the control of TB, but this usage has not been the case with many African countries, including Cameroon. The aims of the present investigation were to identify and evaluate the diversity of the Mycobacterium tuberculosis complex (MTBC) isolates circulating in two ecological zones of Cameroon, seven years after the last studies in the West Region, and after the re-organization of the National TB Control Program (NTBCP). These were expected to shed light also on the transmission of TB in the country. The study was conducted from February to July 2009. During this period, 169 patients with symptomatic disease and with sputum cultures that were positive for MTBC were randomly selected for the study from amongst 964 suspected patients in the savannah mosaic zone (West and North West regions) and the tropical rainforest zone (Central region). After culture and diagnosis, DNA was extracted from each of the MTBC isolates and transported to the BecA-ILRI Hub in Nairobi, Kenya for molecular analysis. METHODS: Genetic characterization was done by mycobacterial interspersed repetitive unit–variable number tandem repeat typing (MIRU-VNTR) and Spoligotyping. RESULTS: Molecular analysis showed that all TB cases reported in this study were caused by infections with Mycobacterium tuberculosis (98.8%) and Mycobacterium africanum (M. africanum) (1.2%) respectively. We did not detect any M. bovis. Comparative analyses using spoligotyping revealed that the majority of isolates belong to major clades of M. tuberculosis: Haarlem (7.6%), Latin American-Mediterranean (34.4%) and T clade (26.7%); the remaining isolates (31.3%) where distributed among the minor clades. The predominant group of isolates (34.4%) corresponded to spoligotype 61, previously described as the “Cameroon family. Further analysis based on MIRU-VNTR profiles had greater resolving power than spoligotyping and defined additional genotypes in the same spoligotype cluster. CONCLUSION: The molecular characterization of MTBC strains from humans in two ecological regions of Cameroon has shown that M. tuberculosis sensu stricto is the predominant agent of TB cases in the zones. Three decades ago, TB was reported to be caused by M. africanum in 56.0% of cases. The present findings are consistent with a major shift in the prevalence of M. tuberculosis in Cameroon

BioTIME: A database of biodiversity time series for the Anthropocene.

MotivationThe BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal patterns of biodiversity in the Anthropocene.Main types of variables includedThe database contains 8,777,413 species abundance records, from assemblages consistently sampled for a minimum of 2 years, which need not necessarily be consecutive. In addition, the database contains metadata relating to sampling methodology and contextual information about each record.Spatial location and grainBioTIME is a global database of 547,161 unique sampling locations spanning the marine, freshwater and terrestrial realms. Grain size varies across datasets from 0.0000000158 km2 (158 cm2) to 100 km2 (1,000,000,000,000 cm2).Time period and grainBioTIME records span from 1874 to 2016. The minimal temporal grain across all datasets in BioTIME is a year.Major taxa and level of measurementBioTIME includes data from 44,440 species across the plant and animal kingdoms, ranging from plants, plankton and terrestrial invertebrates to small and large vertebrates.Software format.csv and .SQL
