Considerable debates still exist regarding choice of antibiotics, dose, and duration of use. Objectives The objective is to compare the efficacy of 2 doses of amoxicillin-clavulanic acid versus a 7 days combination of amoxicillin-clavulanic acid and metronidazole as prophylactic antibiotics following cesarean section (CS). Methodology It was a randomized controlled trial that was conducted among 160 women undergoing CS at Aminu Kano Teaching Hospital. Women were randomized into two groups. Group I (study group) received 2 doses of 1.2 g amoxicillin-clavulanic acid. Group II (control group) received a 7 days course of amoxicillin-clavulanic acid and metronidazole. The data obtained were analyzed using SPSS version 17. Categorical (qualitative) variables were analyzed using Chi-square test and Fisher's exact test as appropriate while continuous (quantitative) variables were analyzed using independent sample t-test. P less th The two doses were cheaper with minimal side effects.Background Acute ischemic stroke is an important cause of morbidity and mortality. Search has been on to find out the factors which can help in formulating the prognosis of acute ischemic stroke. One of the prognostic indicators, which has gained great clinical interest in recent times, is serum ferritin. Aims To assess the serum ferritin levels in patients with acute ischemic stroke and to study the role of serum ferritin as a prognostic marker in these patients. Materials and methods This prospective, observational study was conducted on 50 patients of acute ischemic stroke aged ≥18 years who presented within 48 hours of onset of symptoms. Clinical severity of stroke was assessed at admission and on the 6th day using Canadian Stroke Scale (CSS), and serum ferritin levels were measured at admission and on the 6th day in all these subjects. Results The mean serum ferritin levels at admission in patients with "more severe stroke" (CSS score at admission ≤7) and "less severe stroke" (CSS score at admission >7) were 282.77 ± 120.53 and 205.12 ± 110.96 ng/mL, respectively. The mean serum ferritin levels at admission were 173.71 ± 109.69 ng/mL in subjects who did not deteriorate and 336.86 ± 57.28 ng/mL in those who deteriorated, while the mean serum ferritin levels on the 6th day were 193.29 ± 101.88 and 343.95 ± 52.34 ng/mL in subjects who did not deteriorate and those who deteriorated, respectively. Conclusions Serum ferritin has a significant positive correlation with the severity of acute ischemic stroke (P less then 0.001), and the levels correlate with the outcome of the disease (P less then 0.001); the patients with higher serum ferritin at admission tend to deteriorate more as compared to those with lower levels. Thus, serum ferritin can be used as a prognostic marker in acute ischemic stroke.Background Thyroid disorders are one of the most common endocrine disorders seen globally. Diagnostic challenge may arise both clinically and biochemically because of the multiple function of thyroid hormones (THs). Request for thyroid function test (TFT s) may be based on clinical impression that may suggest thyroid dysfunction or obvious symptoms and signs that are diagnostic of hyperthyroidism or hypothyroidism. Materials and methods This retrospective study looks at the biochemical patterns of TFTs and the clinical impression of thyroid disorders in a rural tertiary institution. Information extracted from the laboratory register includes indication for the test, the hospital number, the gender, the age, and the THs assayed. The corresponding biochemical pattern of the TFT result was established. Results A total of 297 requests were submitted for TH assay; 34 were excluded from the present study because there were no clinical information. There were 239 females and 24 males giving a female-to-male ratio of 9.91. Majority of the requests (36.5%) were for goiters, followed by gynecological disorders (20.9%) and clinical thyroid disorders (17.9%). About 46% (45.8%) of the goiter cases were biochemically euthyroid, whereas 13.5% were biochemically primary hyperthyroid. Among the 47 cases of thyroid disorders by the physician's clinical impression, 27.7% were euthyroid, 17% were biochemically hyperthyroid, and 10.6% were hypothyroid. Of the 55 gynecological disorders assessed, only 7.3% show biochemical evidence of TH alteration with 56.4% being euthyroid. About 47% (46.6%) of those that did routine medical examination had altered TH level that includes hyperthyroidism and hypothyroidism. Conclusion Goiter is the most prevalent thyroid disorder in this environment. Biochemical pattern of thyroid function test in our environment was mostly euthyroid despites clinical features suggestive of thyroid disorders.Background Roadside automobile mechanics are in the course of their work exposed to several hazards that put them at risk of severe debilitating health challenges. This group of workers, however, is reported not to know much about such hazards and to have little or no training on workplace safety. Aim The study aimed to identify the determinants of occupational health hazards among roadside automobile mechanics in Sokoto Metropolis. Methodology This was a descriptive, cross-sectional study, and using a two-stage sampling technique, a total of 205 roadside mechanics were recruited for the study. A semi-structured interviewer-administered questionnaire was used, and the data were imputed into and analyzed using IBM SPSS. Results The mean age of the respondents was 31.10 ± 10.19 years, and over one-third of them (38.1%) were general vehicle repairers. Majority of the respondents had good knowledge of and attitude toward workplace hazards. However, a good proportion (91.0%) of the mechanics felt that their occupation was a risky one and 80.1% ate and 86.1% drank while working. Type of training and job description were the predictors of knowledge of workplace hazards. Job description was the only predictor of attitude. Burns, bruises, headache/dizziness, and cuts were the most reported work-related illnesses and injuries. Conclusion Although most of the auto-mechanics were aware and had good knowledge of workplace hazards, they did not adhere to safety practices in the workplace, mostly due to nonavailability of protective apparels. There is, therefore, need for continuous health education under the platform of the auto-mechanics association so that they can voluntarily adopt safety practices in their workplace.The delivery of education and training in plastic surgery in Sub-Saharan Africa face increasing challenges. These include endemic shortages of plastic surgeons within postgraduate medical school faculties, the erosion of financial and clinical resources for teaching, and more recently, the millennial generation paradigm shift. It is generally accepted that the millennial generation will be more discerning and comfortable in their requirements for web-based learning content to support their education and training in plastic surgery. We reviewed current literature including original and review articles obtained through a search of PubMed database, Medline, Google Scholar, and hand searching of bibliographies of published articles using the keywords social media, Blogs, Twitter, plastic surgery, and millennial generation. This article defines and explores Blogs, Podcasts, and Twitter, as web-based learning tools, and discusses how to leverage social media to maximize their educational value and effectiveness.s.The synthesis and crystal structure (100 K) of the title compound, ammonium bis[salicylaldehyde thiosemicarbazonato(2-)-κ3O,N1,S]iron(III), NH4[Fe(C8H7N3OS)2], is reported. 3-TYP cost The asymmetric unit consists of an octahedral [FeIII(thsa)2]- fragment, where thsa2- is salicylaldehyde thiosemicarbazonate(2-), and an NH4+ cation. Each thsa2- ligand binds via the thiolate S, the imine N and the phenolate O donor atoms, resulting in an FeIIIS2N2O2 chromophore. The ligands are orientated in two perpendicular planes, with the O and S atoms in cis and the N atoms in trans positions. The FeIII ion is in the low-spin state at 100 K. The crystal structure belongs to a category I order-disorder (OD) family. It is a polytype of a maximum degree of order (MDO). Fragments of the second MDO polytype lead to systematic twinning by pseudomerohedry.The solar photocatalysis of water splitting represents a significant branch of enzymatic simulation by efficient chemical conversion and the generation of hydrogen as green energy provides a feasible way for the replacement of fossil fuels to solve energy and environmental issues. We report herein the self-assembly of a CoII-based metal-organic framework (MOF) constructed from 4,4',4,4-(ethene-1,1,2,2-tetrayl)tetrabenzoic acid [or tetrakis(4-carboxyphenyl)ethylene, H4TCPE] and 4,4'-bipyridyl (bpy) as four-point- and two-point-connected nodes, respectively. This material, namely, poly[(μ-4,4'-bipyridyl)[μ8-4,4',4,4-(ethene-1,1,2,2-tetrayl)tetrabenzoato]cobalt(II)], [Co(C30H16O8)(C10H8N2)]n, crystallized as dark-red block-shaped crystals with high crystallinity and was fully characterized by single-crystal X-ray diffraction, PXRD, IR, solid-state UV-Vis and cyclic voltammetry (CV) measurements. The redox-active CoII atoms in the structure could be used as the catalytic sites for hydrogen production via water splitting. The application of this new MOF as a heterogeneous catalyst for light-driven H2 production has been explored in a three-component system with fluorescein as photosensitizer and trimethylamine as the sacrificial electron donor, and the initial volume of H2 production is about 360 µmol after 12 h irradiation.The tridentate organic ligand 4,4',4-(4,4,8,8,12,12-hexamethyl-8,12-dihydro-4H-benzo[9,1]quinolizino[3,4,5,6,7-defg]acridine-2,6,10-triyl)tribenzoic acid (H3L) has been synthesized (as the methanol 1.25-solvate, C48H39NO6·1.25CH3OH). As a donor-acceptor motif molecule, H3L possess strong intramolecular charge transfer (ICT) fluorescence. Through hydrogen bonds, H3L molecules construct a two-dimensional (2D) network, which pack together into three-dimensional (3D) networks with an ABC stacking pattern in the crystalline state. Based on H3L and M(NO3)2 salts (M = Cd and Zn) under solvothermal conditions, two metal-organic frameworks (MOFs), namely, catena-poly[[triaquacadmium(II)]-μ-10-(4-carboxyphenyl)-4,4'-(4,4,8,8,12,12-hexamethyl-8,12-dihydro-4H-benzo[9,1]quinolizino[3,4,5,6,7-defg]acridine-2,6-diyl)dibenzoato], [Cd(C48H37NO6)(H2O)3]n, I, and poly[[μ3-4,4',4-(4,4,8,8,12,12-hexamethyl-8,12-dihydro-4H-benzo[9,1]quinolizino[3,4,5,6,7-defg]acridine-2,6,10-triyl)tribenzoato](μ3-hydroxido)zinc(II)], [Zn2(C48H36NO6)(OH)]n, II, were synthesized. Single-crystal analysis revealed that both MOFs adopt a 3D structure. In I, partly deprotonated HL2- behaves as a bidentate ligand to link a CdII ion to form a one-dimensional chain. In the solid state of I, the existence of weak interactions, such as O-H...O hydrogen bonds and π-π interactions, plays an essential role in aligning 2D nets and 3D networks with AB packing patterns for I. The deprotonated ligand L3- in II is utilized as a tridentate building block to bind ZnII ions to construct 3D networks, where unusual Zn4O14 clusters act as connection nodes. As a donor-acceptor molecule, H3L exhibits fluorescence with a photoluminescence quantum yield (PLQY) of 70% in the solid state. In comparison, the PL of both MOFs is red-shifted with even higher PLQYs of 79 and 85% for I and II, respectively.
