Abstract BACKGROUND: Cranioplasty after decompressive craniectomy (DC) is routinely performed for reconstructive purposes and has been recently linked to improved cerebral blood flow (CBF) and neurological function. OBJECTIVE: To systematically review all available literature to evaluate the effect of cranioplasty on CBF and neurocognitive recovery. METHODS: A PubMed, Google Scholar, and MEDLINE search adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines included studies reporting patients who underwent DC and subsequent cranioplasty in whom cerebral hemodynamics were measured before and after cranioplasty. RESULTS: The search yielded 21 articles with a total of 205 patients (range 3–76 years) who underwent DC and subsequent cranioplasty. Two studies enrolled 29 control subjects for a total of 234 subjects. Studies used different imaging modalities, including CT perfusion (n = 10), Xenon-CT (n = 3), single-photon emission CT (n = 2), transcranial Doppler (n = 6), MR perfusion (n = 1), and positron emission tomography (n = 2). Precranioplasty CBF evaluation ranged from 2 days to 6 months; postcranioplasty CBF evaluation ranged from 7 days to 6 months. All studies demonstrated an increase in CBF ipsilateral to the side of the cranioplasty. Nine of 21 studies also reported an increase in CBF on the contralateral side. Neurological function improved in an overwhelming majority of patients after cranioplasty. CONCLUSION: This systematic review suggests that cranioplasty improves CBF following DC with a concurrent improvement in neurological function. The causative impact of CBF on neurological function, however, requires further study.

Neuroscience research in Africa remains sparse. Devising new policies to boost Africa’s neuroscience landscape is imperative, but these must be based on accurate data on research outputs which is largely lacking. Such data must reflect the heterogeneity of research environments across the continent’s 54 countries. Here, we analyse neuroscience publications affiliated with African institutions between 1996 and 2017. Of 12,326 PubMed indexed publications, 5,219 show clear evidence that the work was performed in Africa and led by African-based researchers - on average ~5 per country and year. From here, we extract information on journals and citations, funding, international coauthorships and techniques used. For reference, we also extract the same metrics from 220 randomly selected publications each from the UK, USA, Australia, Japan and Brazil. Our dataset provides insights into the current state of African neuroscience research in a global context. Here, the authors survey neuroscience publications from Africa over the past two decades, highlighting areas of active research, international networks, funding, and techniques used.

Malnutrition is an independent predictor for postoperative complications in low- and middle-income countries (LMICs). We systematically reviewed evidence on the impact of preoperative oral nutrition supplementation (ONS) on patients undergoing gastrointestinal cancer surgery in LMICs. We searched EMBASE, Cochrane Library, Web of Science, Scopus, WHO Global Index Medicus, SciELO, Latin American and Caribbean Health Sciences Literature (LILACS) databases from inception to March 21, 2022 for randomised controlled trials evaluating preoperative ONS in gastrointestinal cancer within LMICs. We evaluated the impact of ONS on all postoperative outcomes using random-effects meta-analysis. Seven studies reported on 891 patients (446 ONS group, 445 control group) undergoing surgery for gastrointestinal cancer. Preoperative ONS reduced all cause postoperative surgical complications (risk ratio (RR) 0.53, 95% CI 0.46–0.60, P < 0.001, I 2  = 0%, n = 891), infection (0.52, 0.40–0.67, P = 0.008, I 2  = 0%, n = 570) and all-cause mortality (0.35, 0.26–0.47, P = 0.014, I 2  = 0%, n = 588). Despite heterogeneous populations and baseline rates, absolute risk ratio (ARR) was reduced for all cause (pooled effect −0.14, −0.22 to −0.06, P = 0.006; number needed to treat (NNT) 7) and infectious complications (−0.13, −0.22 to −0.06, P < 0.001; NNT 8). Preoperative nutrition in patients undergoing gastrointestinal cancer surgery in LMICs demonstrated consistently strong and robust treatment effects across measured outcomes. However additional higher quality research, with particular focus within African populations, are urgently required.

Abstract The protozoans include many intracellular human pathogens. Accurate detection of these pathogens is necessary to treat the diseases. In clinical epidemiology, molecular identification of protozoan is considered a more reliable and rapid method for identification than microscopy. Among these protozoans, Cryptosporidium considered being one of the important water-borne zoonotic pathogens and a major cause of a diarrheal disease named cryptosporidiosis in humans, domestic animals, and wild animals. This study was aimed to identify Cryptosporidium in zoo felids (N= 56) belonging to different zoo of China, but accidentlly Colpodella was encountered in the zoo felids sample and phylogenetic data confirmed this unexpected amplification from fecal samples using two-step nested-PCR. Phylogenetic analysis revealed the fact about the specific primers used previously by many researchers and cross-genera amplification. We came to know that genetically sequenced amplicon gives more accurate identification of species. This study suggests more investigation on Colpodella which has been neglected previously but gains the attention of researchers after identified from humans and animals and has been known to correlate with neurological symptoms in patients. Resumo Os protozoários incluem muitos patógenos humanos intracelulares. A detecção acurada desses patógenos é necessária para tratar as doenças. Na epidemiologia clínica, a identificação molecular de protozoários é considerada o método de identificação mais confiável e rápido do que a microscopia. Entre esses protozoários, o Cryptosporidium é considerado um dos importantes patógenos zoonóticos transmitidos pela água e uma das principais causas de uma doença diarreica denominada criptosporidiose em humanos, animais domésticos e selvagens. Este estudo teve como objetivo identificar Cryptosporidium em zoofelídeos (N = 56) pertencentes a diferentes zoológicos da China, mas acidentalmente Colpodella foi encontrada na amostra de zoofelídeos e os dados filogenéticos confirmaram essa amplificação inesperada de amostras fecais usando nested-PCR em duas etapas. A análise filogenética revelou o fato sobre os primers específicos usados anteriormente por muitos pesquisadores e a amplificação entre gêneros. Ficamos sabendo que o amplicon sequenciado geneticamente fornece uma identificação mais acurada das espécies. Este estudo sugere mais investigação sobre Colpodella, que foi negligenciada anteriormente, mas ganha a atenção dos pesquisadores depois de identificada em humanos e animais e é conhecida por se correlacionar com sintomas neurológicos em pacientes.

Abstract The medicinal attributes of honey appears to overshadow its importance as a functional food. Consequently, several literatures are rife with ancient uses of honey as complementary and alternative medicine, with relevance to modern day health care, supported by evidence-based clinical data, with little attention given to honey’s nutritional functions. The moisture contents of honey extracted from University of Veterinary and Animal Sciences, Lahore honey bee farm was 12.19% while that of natural source was 9.03 ± 1.63%. Similarly, ash and protein contents of farmed honey recorded were 0.37% and 5.22%, respectively. Whereas ash and protein contents of natural honey were 1.70 ± 1.98% and 6.10 ± 0.79%. Likewise fat, dietary fiber and carbohydrates contents of farmed source documented were 0.14%, 1.99% and 62.26% respectively. Although fat, dietary fiber and carbohydrates contents of honey taken from natural resource were 0.54 ± 0.28%, 2.76 ± 1.07% and 55.32 ± 2.91% respectively. Glucose and fructose contents of honey taken out from honeybee farm were 27% and 34% but natural source were 22.50 ± 2.12% and 28.50 ± 3.54%. Glucose and fructose contents of honey taken out from honeybee farm were 27% and 34% but natural source were 22.50 ± 2.12% and 28.50 ± 3.54%. Similarly, sucrose and maltose contents of farmed honey were 2.5% and 12% while in natural honey were 1.35 ± 0.49% and 8.00 ± 1.41% respectively. The present study indicates that such as moisture, carbohydrates, sucrose and maltose contents were higher farmed honey as compared to the natural honey. In our recommendation natural honey is better than farmed honey. Resumo Os atributos medicinais do mel parecem ofuscar sua importância como alimento funcional. Consequentemente, várias literaturas estão repletas de usos antigos do mel como medicina complementar e alternativa, com relevância para os cuidados de saúde modernos, apoiados por dados clínicos baseados em evidências, com pouca atenção dada às funções nutricionais do mel. O teor de umidade do mel extraído da Universidade de Veterinária e Ciências Animais, fazenda de abelhas de Lahore, foi de 12,19%, enquanto o de fonte natural foi de 9,03 ± 1,63%. Da mesma forma, os teores de cinzas e proteínas do mel cultivado foram de 0,37% e 5,22%, respectivamente. Já os teores de cinzas e proteínas do mel natural foram de 1,70 ± 1,98% e 6,10 ± 0,79%. Da mesma forma, os teores de gordura, fibra dietética e carboidratos de origem cultivada documentados foram de 0,14%, 1,99% e 62,26%, respectivamente. Embora os teores de gordura, fibra alimentar e carboidratos do mel retirado dos recursos naturais fossem de 0,54 ± 0,28%, 2,76 ± 1,07% e 55,32 ± 2,91%, respectivamente. Os conteúdos de glicose e frutose do mel retirado da fazenda de abelhas foram de 27% e 34%, mas a fonte natural foi de 22,50 ± 2,12% e 28,50 ± 3,54%. Os conteúdos de glicose e frutose do mel retirado da fazenda de abelhas foram de 27% e 34%, mas a fonte natural foi de 22,50 ± 2,12% e 28,50 ± 3,54%. Da mesma forma, os teores de sacarose e maltose no mel cultivado foram de 2,5% e 12%, enquanto no mel natural foram de 1,35 ± 0,49% e 8,00 ± 1,41%, respectivamente. O presente estudo indica que os teores de umidade, carboidratos, sacarose e maltose foram maiores no mel cultivado em comparação ao mel natural. Em nossa recomendação, o mel natural é melhor que o mel de cultivo.

BackgroundEpilepsy is a major cause of morbidity and mortality in meningioma patients. The aims of this study were to determine which factors predispose meningioma patients to developing perioperative seizures and to understand the impact of antiepileptic drugs.MethodsPatients treated for a histologically-confirmed intracranial meningioma at the authors’ institution between 2010 and 2015 were retrospectively examined. Clinical and imaging data were assessed. Multivariate analysis was performed using binary logistic regression. The effect of antiepileptic treatment was assessed using survival analysis.ResultsTwo hundred and eighty-three patients met the selection criteria; seizures were present in 68 preoperatively (24%) and in 48 patients (17%) following surgery. Of the 68 with preoperative seizures, 19 continued to have them, whereas de-novo seizures arose postoperatively in 29 seizure-naïve patients. Risk factors of postoperative seizures were convexity location (OR 2.05 [95% CI 1.07–3.98], p = 0.030), fronto-parietal location (OR 4.42 [95% CI 1.49–13.16], p = 0.007) and preoperative seizures (OR 2.65 [95% CI 1.37–5.24], p = 0.005). The two locations, in addition to the presence of midline shift on preoperative imaging (OR 4.15 [95% CI 1.54–11.24], p = 0.005), were significantly correlated with postoperative seizures in seizure-naïve patients. Antiepileptic treatment in patients with those risk factors reduced the possibility of seizures at any time point within the 1st year postoperatively by approximately 40%, although this did not meet statistical significance.ConclusionProphylactic antiepileptic treatment might be warranted in seizure-naïve meningioma patients with ≥ 1 risk factor. High-quality randomised controlled trials are required to verify those factors and to define the role of antiepileptics in meningioma practice.

Abstract The objective of this study was to evaluate the effectiveness of common antibiotics against different microorganisms in apparently healthy cattle in Shandong province and its suburb. A total of 220 nasal swab samples were collected and cultured for bacteriological evaluation. All the bacteria isolates after preliminary identification were subjected to antibiogram studies following disc diffusion method. It was found in the study that E. coli is the most commonly associated isolate (21%), followed by Klebsiella spp. (18%), Pseudomonas aeruginosa (13%), Salmonella spp. (15%), Shigella spp (12%), and Proteus spp (11%). While the antibiogram studies reveled that highest number of bacterial isolates showed resistance to Ampicillin (95%), followed by Augmentin (91%), Cefuroxime (85%) and Tetracycline (95%) of (Escherichia coli and Klebsiella spp). In the case of pseudomonas spp. and Salmonella the highest resistance was showed by Ampicillin (90%) followed by Amoxicillin + Clavulanic Acid (80%), Cefixime (90%), and Erythromycin (80%). In Shigella spp and Salmonella spp highest resistance was showed by Amoxicillin, Ceftazidime, Augmentin (60%), and Amoxicillin + Clavulanic Acid (50%). It is concluded that in vitro antibiogram studies of bacterial isolates revealed higher resistance for Ampicillin, Augmentin, Cefuroxime, Cefixime, Tetracycline, Erythromycin, and Amoxicillin + Clavulanic Acid. The high multiple Antibiotics resistance indexes (MARI) observed in all the isolates in this study ranging from 0.6 to 0.9. MARI value of >0.2 is suggests multiple antibiotic resistant bacteria and indicate presence of highly resistant bacteria. Resumo O objetivo deste estudo foi avaliar a eficácia dos antibióticos comuns contra diferentes microrganismos em bovinos aparentemente saudáveis na província de Shandong e seus subúrbios. Um total de 220 amostras de esfregaço nasal foi coletado e cultivado para avaliação bacteriológica. Todos os isolados de bactérias após identificação preliminar foram submetidos a estudos de antibiograma seguindo o método de difusão em disco. Verificou-se no estudo que E. coli é o isolado mais comumente associado (21%), seguido por Klebsiella spp. (18%), Pseudomonas aeruginosa (13%), Salmonella spp. (15%), Shigella spp (12%) e Proteus spp (11%). Enquanto os estudos de antibiograma revelaram que o maior número de isolados bacterianos apresentou resistência à Ampicilina (95%), seguido por Augmentin (91%), Cefuroxima (85%) e Tetraciclina (95%) de (Escherichia coli e Klebsiella spp). No caso de Pseudomonas spp. e Salmonella, a maior resistência foi apresentada pela Ampicilina (90%) seguida pela Amoxicilina + Ácido Clavulânico (80%), Cefixima (90%) e Eritromicina (80%). Em Shigella spp e Salmonella spp, a maior resistência foi demonstrada por Amoxicilina, Ceftazidima, Augmentina (60%) e Amoxicilina + Ácido Clavulânico (50%). Conclui-se que estudos de antibiograma in vitro de isolados bacterianos revelaram maior resistência para Ampicilina, Augmentina, Cefuroxima, Cefixima, Tetraciclina, Eritromicina e Amoxicilina + Ácido Clavulânico. Os altos índices de resistência a antibióticos múltiplos (MARI) observados em todos os isolados neste estudo variaram de 0,6 a 0,9. O valor MARI de > 0,2 sugere várias bactérias resistentes a antibióticos e indica a presença de bactérias altamente resistentes.

Objective: To determine the delay in diagnosis of various types of congenital heart defects in children and factors associated with such delay. Patients and Methods: For this observational study, 354 patients having congenital heart disease (CHD) presenting for the first time to the Department of Cardiology, Children's Hospital, Lahore, Pakistan, between January 1, 2015 and June 30, 2015, were enrolled after obtaining informed verbal consent from the guardian of each child. Demographical profile and various factors under observation were recorded. Results: Among the 354 enrolled children (M: F 1.7:1) with age ranging from 1 to 176 months (median 24 months), 301 (85.1%) had delayed diagnosis of CHD (mainly acyanotic 65.3%), with median delay (8 months). Main factors for delay were delayed first consultation to a doctor (37.2%) and delayed diagnosis by a health professional (22.5%). Other factors included delayed referral to a tertiary care hospital (13.3%), social taboos (13.0%), and financial constraints (12.3%). Most children were delivered outside hospital settings (88.7%). Children with siblings less than two (40%) were less delayed than those having two or more siblings (60%, P < 0.001). Conclusion: Diagnosis of congenital heart defect was delayed in majority of patients. Multiple factors such as lack of adequately trained health system and socioeconomic constraints were responsible for the delay. There is a need to develop an efficient referral system and improve public awareness in developing countries for early diagnosis and management of such children.

Abstract Tapeworms of zoonotic importance have been described as a leading public health problem. Current research was aim to assess the prevalence of tapeworms among 5-12years school children residing in district Lower Dir, Pakistan from January 2019-December 2019. The wet mount preparation in saline/iodine/methods were used for stool examination. Data was analyzed using appropriate descriptive, static methods. Of the 400 children studied 71.7% were infected with one or more species of intestinal parasites. Single infection of cestode species was found in 69 individuals with 17.2% prevalence and multiple parasitic infections were identified in 19.7% (n=79/400) individuals. The multiple infection were comprised as 10% (n=40) double, 6.75% (n=27) triple and 3% (n=12) quadruple. A total of 9 species of helminths and one species of protozoan infection. Among the helminths Ascaris lumbricoides was the most prevalent 33.1% (n=95), Taenia saginata 22.6% (n=65), hookworm 19.8% (n=57), Hymenolepis nana 18.8% (n=54), Enterobius vermicularis and Hymenolepis diminuta 1.39% (n=4each), Trichuris trichura 1.04% (n=3), Toxocara spp 0.69% (n=2) and Schistosoma japonicum 0.34% (n=1) were reported. One protozoan species was Cryptosporidium spp 0.69% (n=2) in current study. In case of A.lumbricoides, hookworm, E.vermicularis, T.trichura, T.saginata, H.nana and H.diminuta the male children of below 8 years of age were highly infected. Other infections are reported in the same prevalence with slight difference if any. We conclude that there is a need for mass scale campaigns to create awareness regarding health and hygiene in children and the need for development of effective poverty control programs because deworming alone is not adequate to control parasitic infections. Resumo As tênias de importância zoonótica têm sido descritas como um dos principais problemas de saúde pública. A pesquisa atual teve como objetivo avaliar a prevalência de tênias entre crianças em idade escolar de 5 a 12 anos que residem no distrito de Lower Dir, Paquistão, de janeiro de 2019 a dezembro de 2019. Os métodos de preparação para montagem úmida em solução salina/iodo foram usados para exame de fezes. Os dados foram analisados usando métodos descritivos e estáticos apropriados. Das 400 crianças estudadas, 71,7% estavam infectadas com uma ou mais espécies de parasitas intestinais. Infecção única de espécies de cestóides foi encontrada em 69 indivíduos com prevalência de 17,2% e infecções parasitárias múltiplas foram identificadas em 19,7% (n = 79/400) indivíduos. As infecções múltiplas foram compostas por 10% (n = 40) dupla, 6,75% (n = 27) tripla e 3% (n = 12) quádrupla. Um total de 9 espécies de helmintos e uma espécie de infecção por protozoários. Entre os helmintos, Ascaris lumbricoides foi o mais prevalente 33,1% (n = 95), Taenia saginata 22,6% (n = 65), ancilóstomo 19,8% (n = 57), Hymenolepis nana 18,8% (n = 54), Enterobius vermicularis e Hymenolepis diminuta 1,39% (n = 4cada), Trichuris trichura 1,04% (n = 3), Toxocara spp 0,69% (n = 2) e Schistosoma japonicum 0,34% (n = 1). Uma espécie de protozoário foi Cryptosporidium spp 0,69% (n = 2) no estudo atual. No caso de A.lumbricoides, ancilostomíase, E.vermicularis, T.trichura, T.saginata, H.nana e H.diminuta, as crianças do sexo masculino com menos de 8 anos de idade estavam altamente infectadas. Outras infecções são relatadas na mesma prevalência, com ligeira diferença, se houver. Concluímos que há uma necessidade de campanhas em massa para criar consciência sobre saúde e higiene em crianças e a necessidade de desenvolvimento de programas eficazes de controle da pobreza, porque a desparasitação por si só não é adequada para controlar infecções parasitárias.
