Spinal manipulation or mobilization for lumbar disc herniation with radiculopathy : a protocol for a systematic review and meta-analysis

Introduction: The purpose of this study is to conduct a systematic review and meta-analysis into the effects of spinal manipulation or mobilization for Lumbar Disc Herniation with Radiculopathy (LDHR). Methods: An electronic database search of titles and abstracts of articles published in English will be conducted in the following databases: PEDro (Physiotherapy Evidence Database), CINAHL (Cumulative Index to Nursing and Allied Health Literature), PubMed, Science Direct, Google Scholar, and The Cochrane Library. The specific search strategies will be dependent on the particular database being searched and hand searches of the reference lists of the included articles will also be performed. Studies will be included if they reported an acceptable comparison group, and also reported at least one of the main clinically relevant outcome measures for LDHR. Two independent reviewers will screen the identified records, and all disagreements will be resolved. The internal and external validities of the included studies will be assessed using the PEDro scale and the External Validity Assessment Tool (EVAT) respectively. The clinical relevance and risk of bias of the studies will be determined using the 5-Criteria developed by the Cochrane Back Review Group and the Cochrane Risk of Bias Assessment Tool respectively. Studies will be pooled into meta-analysis where appropriate using RevMan software and the outcomes will be reported using the PRISMA guidelines. Discussion: This review will summarize the current evidence about the effects of spinal manipulation or mobilization compared with other interventions in the management of individuals with Lumbar Disc Herniation with Radiculopathy (LDHR). A meta-analysis will also be conducted where appropriate in this review to compare the effects of spinal manipulation or mobilization with other interventions with a view to finding out which technique is better in the management of individuals with LDHR. Review Registration: This review has been registered with the International Prospective Register of Systematic Reviews (PROSPERO; registration number: CRD42019131292).

Assessing the validity of western measurement of online risks to children in an Asian context

Before the advent of the Internet, television with limited channels was the only media choice that most children were exposed to, and took place under family supervision. Children’s television viewing was controllable and the risks were limited to watching sexual and violent content. Nowadays, children are surrounded by a variety of digital media and are exposed to many different risks, many of which are still unknown and under-researched. For many children, the Internet is fully integrated into their daily lives, along with the potential risks. The present study aimed to (i) describe the level of risks children are exposed to, and (2) test the measurement validity of a total of 45 items assessing nine scales online risky behavior in children were adapted from studies carried out in Europe and the United States. The study comprised 420 school going children aged 9, 11, 13, 14, and 16 studying in Malaysia. Descriptive analyses showed that children were more exposed to ‘unwanted exposure to pornography’ and less to ‘conduct risk’. Boys and older children were more exposed to the risks compared to girls and younger children. The study validated five dimensions (inappropriate materials, sexting, contact-related risks on, risky online sexual behavior, and bullying/being bullied) assessing children’s online risky behavior by using exploratory and confirmatory factor analyses. Further research is needed to investigate the measurement of children’s online risk, since the scales developed in Europe and the United States are not wholly suitable to an Asian context

Assessment of genetic diversity in French bean (Phaseolus vulgaris L) based on RAPD marker

RAPD molecular markers were used to evaluate the genetic diversity in the fourteen varieties of French bean (Phaseolus vulgaris) of three eco-geographical regions of Bangladesh. Out of the 20 primers only, 6 yielded polymorphic banding patterns. In total, 40 different DNA bands were reproducibly obtained, out of which 28 (70%) were polymorphic. The polymorphisms were scored and used in band-sharing analysis to identify genetic relationships. Cluster analysis based on Jaccard’s similarity coefficient using UPGMA grouped all the 14 genotypes into two major groups. Pair-wise variety comparison of the varieties showed that inter-variety similarity indices for PV004 versus PV005 (98.51) was higher than all other varietals pairs. On the other hand, inter-cultivar similarity index for BARI 01 versus PV009 (59.58) cultivar was lower than all other cultivar pairs. Therefore, the inherent simplicity and efficiency of RAPD analyses will be to facilitate the construction of RAPD-based genetic linkage maps in French bean.Key words: RAPD, French bean, polymorphism

Anti-Inflammatory Activity of Crude Saponin Extracts from Five Nigerian Medicinal Plants

Crude saponin extracts of five medicinal plants used in the treatment of inflammatory diseases like rheumatoid arthritis, gout and haemorrhoids were screened for anti-inflammatory activity using carrageenan-induced rat paw oedema test. These plants were the whole plant of Schwenkia americana Linn (WSA), the rhizomes of Asparagus africanus Lam (RAA), the leaves of Dichrostachys cinerea Linn (LDC), the stem bark of Ficus iteophylla Miq (BFI) and the leaves of Indigofera pulchra Willd (LIP). A modify traditional method of crude saponins extraction was used to give the following percentage yields: WSA-2.74%, RAA-3.59%, LDC-1.62%, BFI-0.81% and LIP-1.57% respectively. Thin-layer chromatography was used to identify the type of saponins present in the extracts. The acute toxicity study of the crude saponin extracts in mice gave the following intraperitoneal LD50: WSA-471.2mg/kg, RAA- 1264.9mg/kg, LDC-1264.9mg/kg, BFI-118.3mg/kg and LIP-1264.9mg/kg respectively.  The antiinflammatory study of the extracts showed statistically significant (P<0.05) decreases in the rat paw-oedema as compared to the control. The percentage inhibitions of the extracts after four hours were as follow: WSA-61%, RAA-55%, LDC-72%, BFI-66% and LIP-40% respectively. These values were found to be comparable to that of ketoprofen-63%. The study showed that the antiinflammatory properties attributable to these plants may be due to their saponins contents.Keywords: - Asparagus africanus, Dichrostachys cinerea, Ficus iteophylla, Indigofera pulchra, Schwenkia americana, Saponin,Anti-inflammatory activity, Carrageenan, TLC

Studies on Growth, Organs Weight and Haematological Parameters of Broiler Chicken Fed Graded Level of Sun Dried Cassava Root Meal

Ninety (90) day old broiler chicks were used to investigate the response of broilers fed sun-dried cassava root meal (CRM). Five diets at starter and finisher phases in which CRM replaced maize at 0, 25, 50, 75 and 100% and designated T1, T2, T3, T4 and T5 respectively. Diets were allocated to day old broiler chicks in a completely randomized design (CRD). Birds were raised on dip-litter system and the experiment lasted for eight (8) weeks. Feed intake was taken daily, while body weights were recorded weekly. On days 22 and 44 two millilitres (2ml) of blood were collected using sterile syringe and needle from the wing vein into vacutainer tubes containing 2mg ethylene diamine tetra acetic acid (EDTA) as anticoagulant from two birds in each replicate. At eight weeks of age, two birds per replicate were randomly selected and used for carcass analysis. At the starter phase, final weight, daily weight gain and feed intake were significantly (P<0.05) higher in T1 and T2 compared to other treatments. Feed conversion efficiency tend to increase as the inclusion level of CRM increased at (P<0.05). No significant difference (P>0.05) was observed among the treatments for haematological parameters (PCV, Hb, MCHC and Total Protein). Highest mortality at starter and finisher phases were recorded in T4 and T5. Generally, there was decrease in feed intake as the inclusion level of CRM increased. Inclusion of CRM at finisher phase significantly affects the weight of some internal organs in T2, T3 and T4 (P<0.05). It is concluded that cassava root meal could be used to replace maize up to 25% without any adverse effect on the performance of broiler chicken

Screening for diabetes mellitus in learners residing in the Belhar, Delft and Mfuleni communities of Cape Town, Western Cape, South Africa

Background Historically, children and adolescents have been diagnosed with type 1 diabetes mellitus and it was thought that type 2 diabetes mellitus occurred only in adults. There are increasing reports of type 2 diabetes in children globally, with some as young as eight years old being affected. The average age of diagnosis in this group was 13 years. This has been attributed to the “epidemic” of overweight and obesity currently being observed in both developed and developing countries. There is a paucity of data on the incidence and prevalence of type 2 diabetes mellitus in children compared with that for adults. Most studies reported to date have been clinic based. The few population-based studies that were carried out between 1965 and 1995 have shown a several-fold increase in the incidence rates of type 2 diabetes mellitus. The prevalence of diabetes mellitus in South Africa has risen dramatically in the past two decades, with the highest prevalence rates being found in the adult population of Indian origin, followed by the African, Coloured (mixed ancestry) and White population groups.Objectives This study was undertaken to screen 10 to 16-year-old learners residing in three urban areas of Cape Town, South Africa for diabetes mellitus.Methods Fasting and casual blood glucose levels were measured using a commercial glucometer in 338 randomly selected schoolchildren aged from 10 to 16 from the urban communities of Belhar, Delft and Mfuleni in Cape Town. Early morning urine samples were also tested for the presence of glucose using dipsticks. Anthropometric measurements were carried out using standard procedures. A structured questionnaire on physical activity, demographics and diabetic status was administered to all participants. Overweight and obesity were estimated according to The International Obesity Task Force (IOTF) criteria.Results A total of 15.7% of the learners were overweight and 6.2% were obese; 11.5% of the learners had a first-degree relative with diabetes and 29.9% had a second-degree relative with diabetes. Mean fasting and casual glucose values of 4.26 ± 0.63 mmol/l and 4.58 ± 0.79 mmol/l (pConclusionThese results suggest that population screening of children may not be viable, despite the increase in the prevalence of diabetes mellitus amongst various racial groups in South Africa.For full text, click here: SA Fam Pract 2006;48(6):16-16

Genotypic and phenotypic patterns of antimicrobial susceptibility of Helicobacter pylori strains among Egyptian patients

Helicobacter pylori (H. pylori) is currently recognized as one of the most common chronic bacterial infections worldwide. Eradication of bacteria is effective in healing peptic ulcers, preventing ulcer relapses, and potentially decreasing the risk of progression to gastric carcinoma. For successful eradication of bacteria, it is imperative that the clinician be aware of the current antimicrobial susceptibility profiles of isolates within the region. Therefore, the aim of this study is to compare the phenotypic and genotypic patterns of antibiotics’ susceptibility to H. pylori strains among Egyptian patients. 60 symptomatic cases were enrolled. H. pylori infection was diagnosed by upper endoscopy as well as biopsy. Antimicrobial susceptibility to H. pylori strains was assessed in all subjects by disc diffusion and Ellipsometer testing (E-testing) methods. Further molecular characterization of gene

POL4 and most of its constituents have not been studied widely for its therapeutic use in hypertension. This study is aimed to determine the efficacy and possible insight into mechanism(s) for the medicinal use of POL4 and its ingredients in hypertension

Fractional extracts of Azadirachta indica leaf affect spermiogram, testosterone profile, and testis histology of rabbit bucks

The effect of fractions from a crude extract of Azadirachta indica leaves on spermatogenesis, testicular histology and testosterone concentration of New Zealand White rabbits were evaluated in this study. Twenty-five matured male New Zealand White rabbits were used for this study and were randomly assigned to five groups (A, B, C, D, and E). Group A served as the control and was administered distilled water (0.5ml); while groups B, C, D and E served as the hexane, chloroform, ethyl acetate, and butanol treated groups, respectively at the same dosage of 300 mg/kg. Semen samples were collected using an artificial vagina weekly for twelve weeks and were evaluated for volume, colour, motility, concentration, percentage live-dead ratio and morphological abnormalities. A blood sample (2ml) was also collected from each buck through venipuncture of the ear vein three times at regular intervals for the determination of testosterone concentration. Two bucks from each group were humanely sacrificed at the end of the experiment for testicular histology. Significantly lower (p<0.05) sperm motility, higher dead sperm cells, sperm abnormalities, degenerative changes, depletion and vacuolation of spermatogenic cell layers were observed in treatment group C at the end of the experiment. The present study has shown that the chloroform fraction of methanolic crude Azadirachta indica (neem) leaves extract is detrimental to sperm cells and testicular histology
