Low birth weight among adolescents at Cape Coast Metropolitan Hospital of Ghana

Background: Few studies have focused on low birth weight among adolescents. This study determines the incidence and factors associated with low birth weight (LBW) (weight at birth of less than 2,500 grams) among adolescents (aged <20 years) and how they differ from those in adult mothers (aged ≥20 years).Methods: The records of 768 deliveries at a hospital in Ghana from August 2014 to March 2015 were analyzed. Frequencies and percentages were generated. Bivariate relationships between maternal and neonatal characteristics and LBW were assessed using Chi-squared test. Multivariate logistic regression was used to evaluate the association between maternal age (being adolescent) and LBW. Odds ratios with 95% confidence interval were generated, and p < 0.05 was considered significant.Results: The incidence of LBW among adolescents was 14.3% and this was higher than the one among babies born to adult mothers (14.3 % vs. 7.4 %, p <0.013). Adolescent mothers were twice as likely to give birth to babies with LBW compared to adult mothers (OR 2.22; 95% CI: 1.16 - 4.25). Preterm birth was significantly associated with LBW among adolescent and adult mothers.Conclusions: Adolescents are at a higher risk of giving birth to babies of LBW than adults. Factors predicting LBW may not be different for adolescent and adult mothers. Interventions for prevention of negative sexual health outcomes should focus on adolescents

Citrus reticulata fruit peel extract ameliorates testesterone-induced benign prostatic hyperplasia-like phenotypes in rats

Benign prostatic hyperplasia is a major pathophysiologic event that presents a high risk for prostate cancer (the second most frequently diagnosed cancer in men). The prognosis of conventional therapy for BPH remains poor due to treatment failures. Thus, natural remedies such as botanical drugs remain a promising alternative therapy to be explored for the treatment of BPH and prostate cancer. Citrus fruits, specifically fruit peels of Citrus reticulata (CRE) contain bioactive compounds that exhibit anti-inflammatory properties and have been used in crude form in traditional settings to manage benign prostatic hyperplasia and prostate cancer, however, scientific scrutiny of this ethnobotanical claim remains incomplete. This study assessed the protective effect of CRE in testosterone-induced benign prostatic hyperplasia-like phenotypes in rats. Male Wistar rats (n = 30, 150-200 g) were randomly assigned into six groups (n = 5), and treated for 28 days as follows: control group (normal saline, 5 mg/kg s.c.), model group (testosterone,5 mg/kg, i.p.), the finasteride (1 mg/kg, p.o.), and CRE (50, 100, and 200 mg/kg, p.o.) groups received testosterone (5 mg/kg, i.p.) in the morning and their respective treatments (either finasteride or CRE). All rats were given chow and water ad libitum. On the 28th day, the rats were sacrificed following deep anesthesia. Blood and the prostate gland were collected. Full blood count, serum levels of prostate-specific antigen (PSA), testosterone, C-reactive protein (CRP), and histology of the prostate gland were assessed. Compared to the model, treatment with C. reticulata peel extracts markedly reduced prostate weight, attenuated atresia of the prostatic glands, stromal fibrosis, and mast cell infiltration, and increased glandular secretion. Additionally, serum levels of testosterone, CRP, PSA, and white blood count were reduced in the high-dose C. reticulata peel extract-treated group. Fruit peels of C. reticulata exhibited a protective effect against BPH partly by attenuating inflammatory activity. Thus, this finding provides a rationale for further exploration of CRE for novel anti-BPH molecules that could be used to develop therapeutics against prostate cancer

Palm weevil larvae (Rhynchophorus phoenicis Fabricius) and orange-fleshed sweet potato-enriched biscuits improved nutritional status in female Wistar albino rats

Edible insects have emerged as an inexpensive alternative source of protein for reducing the burden of malnutrition worldwide. However, there is a dearth of evidence on its efficacy, and thus, the aim of this study was to investigate the effect of edible insect consumption on the nutritional status of female Wistar albino rats. The study assessed the subchronic effect of palm weevil larvae (PWL) and orange-fleshed sweet potato- (OFSP-) enriched biscuits (fortified biscuits (FB), plain biscuits (PB), biscuits fortified with PWL (PWB), and biscuits fortified with OFSP only (SPB)) as a model to predict the potential of PWL to improve the nutritional status of pregnant women in Ghana. Twenty-five female Wistar albino rats were randomly assigned to five experimental groups to receive one of the five feed supplements for 28 days. After which, the effects of treatment on haematological and biochemical parameters including lipid profile were assessed. No significant differences were observed with haematological (Hb) parameters. However, total cholesterol levels of the FB, PB, PWB, and SPB were significantly higher than in the N group. Apart from elevated total cholesterol concentrations, biscuits fortified with PWL had no adverse effects and can be a nutritious snack for maintaining acceptable HB levels

Combined transplantation of hiPSC-NSC and hMSC ameliorated neuroinflammation and promoted neuroregeneration in acute spinal cord injury

Abstract Background Spinal cord injury (SCI) is a serious clinical condition that has pathological changes such as increased neuroinflammation and nerve tissue damage, which eventually manifests as fibrosis of the injured segment and the development of a spinal cord cavity leading to loss of function. Cell-based therapy, such as mesenchymal stem cells (MSCs) and neural stem cells (NSCs) are promising treatment strategies for spinal cord injury via immunological regulation and neural replacement respectively. However, therapeutic efficacy is rare reported on combined transplantation of MSC and NSC in acute mice spinal cord injury even the potential reinforcement might be foreseen. Therefore, this study was conducted to investigate the safety and efficacy of co-transplanting of MSC and NSC sheets into an SCI mice model on the locomotor function and pathological changes of injured spinal cord. Methods To evaluate the therapeutic effects of combination cells, acute SCI mice model were established and combined transplantation of hiPSC-NSCs and hMSCs into the lesion site immediately after the injury. Basso mouse scale was used to perform the open-field tests of hind limb motor function at days post-operation (dpo) 1, 3, 5, and 7 after SCI and every week after surgery. Spinal cord and serum samples were collected at dpo 7, 14, and 28 to detect inflammatory and neurotrophic factors. Hematoxylin–eosin (H&E) staining, masson staining and transmission electron microscopy were used to evaluate the morphological changes, fibrosis area and ultrastructure of the spinal cord. Result M&N transplantation reduced fibrosis formation and the inflammation level while promoting the secretion of nerve growth factor and brain-derived neurotrophic factor. We observed significant reduction in damaged tissue and cavity area, with dramatic improvement in the M&N group. Compared with the Con group, the M&N group exhibited significantly improved behaviors, particularly limb coordination. Conclusion Combined transplantation of hiPSC-NSC and hMSC could significantly ameliorate neuroinflammation, promote neuroregeneration, and decrease spinal fibrosis degree in safe and effective pattern, which would be indicated as a novel potential cell treatment option.

Clinical efficacy on glycemic control and safety of mesenchymal stem cells in patients with diabetes mellitus: Systematic review and meta-analysis of RCT data.

BackgroundDiabetes mellitus as a chronic metabolic disease is threatening human health seriously. Although numerous clinical trials have been registered for the treatment of diabetes with stem cells, no articles have been published to summarize the efficacy and safety of mesenchymal stem cells (MSCs) in randomized controlled trials (RCTs).Methods and findingsThe aim of this study was to systematically review the evidence from RCTs and, where possible, conduct meta-analyses to provide a reliable numerical summary and the most comprehensive assessment of therapeutic efficacy and safety with MSCs in diabetes. PubMed, Web of Science, Ovid, the Cochrane Library and CNKI were searched. The retrieval time was from establishment of these databases to January 4, 2020. Seven RCTs were eligible for analysis, including 413 participants. Meta-analysis results showed that there were no significant differences in the reduction of fasting plasma glucose (FPG) compared to the baseline [mean difference (MD) = -1.05, 95% confidence interval (CI) (-2.26,0.16), PConclusionsThis meta-analysis revealed MSCs therapy may be an effective and safe intervention in subjects with diabetes. However, due to the limited studies, a number of high-quality as well as large-scale RCTs should be performed to confirm these conclusions

Generation and characterization of a human induced pluripotent stem cell (iPSC) line (HEBHMUi001-A) from a sporadic Parkinson's disease patient

We generated a human induced pluripotent stem cell (iPSC) line from the skin fibroblasts of a 62-year-old female patient clinically diagnosed with sporadic Parkinson's disease (PD). The generated iPSCs maintained their normal karyotype, expressed pluripotency stem cell markers, and were demonstrated to be capable of differentiating into cells representative of the three embryonic germ layers. The generated line could be used for PD modeling in order to understand the mechanisms that influence the disorder

Amelioration of diabetic nephropathy in mice by a single intravenous injection of human mesenchymal stromal cells at early and later disease stages is associated with restoration of autophagy

Abstract Background and aims Mesenchymal stromal cells (MSCs) a potentially effective disease-modulating therapy for diabetic nephropathy (DN) but their clinical translation has been hampered by incomplete understanding of the optimal timing of administration and in vivo mechanisms of action. This study aimed to elucidate the reno-protective potency and associated mechanisms of single intravenous injections of human umbilical cord-derived MSCs (hUC-MSCs) following shorter and longer durations of diabetes. Methods A streptozotocin (STZ)-induced model of diabetes and DN was established in C57BL/6 mice. In groups of diabetic animals, human (h)UC-MSCs or vehicle were injected intravenously at 8 or 16 weeks after STZ along with vehicle-injected non-diabetic animals. Diabetes-related kidney abnormalities was analyzed 2 weeks later by urine and serum biochemical assays, histology, transmission electron microscopy and immunohistochemistry. Serum concentrations of pro-inflammatory and pro-fibrotic cytokines were quantified by ELISA. The expression of autophagy-related proteins within the renal cortices was investigated by immunoblotting. Bio-distribution of hUC-MSCs in kidney and other organs was evaluated in diabetic mice by injection of fluorescent-labelled cells. Results Compared to non-diabetic controls, diabetic mice had increases in urine albumin creatinine ratio (uACR), mesangial matrix deposition, podocyte foot process effacement, glomerular basement membrane thickening and interstitial fibrosis as well as reduced podocyte numbers at both 10 and 18 weeks after STZ. Early (8 weeks) hUC-MSC injection was associated with reduced uACR and improvements in multiple glomerular and renal interstitial abnormalities as well as reduced serum IL-6, TNF-α, and TGF-β1 compared to vehicle-injected animals. Later (16 weeks) hUC-MSC injection also resulted in reduction of diabetes-associated renal abnormalities and serum TGF-β1 but not of serum IL-6 and TNF-α. At both time-points, the kidneys of vehicle-injected diabetic mice had higher ratio of p-mTOR to mTOR, increased abundance of p62, lower abundance of ULK1 and Atg12, and reduced ratio of LC3B to LC3A compared to non-diabetic animals, consistent with diabetes-associated suppression of autophagy. These changes were largely reversed in the kidneys of hUC-MSC-injected mice. In contrast, neither early nor later hUC-MSC injection had effects on blood glucose and body weight of diabetic animals. Small numbers of CM-Dil-labeled hUC-MSCs remained detectable in kidneys, lungs and liver of diabetic mice at 14 days after intravenous injection. Conclusions Single intravenous injections of hUC-MSCs ameliorated glomerular abnormalities and interstitial fibrosis in a mouse model of STZ-induced diabetes without affecting hyperglycemia, whether administered at relatively short or longer duration of diabetes. At both time-points, the reno-protective effects of hUC-MSCs were associated with reduced circulating TGF-β1 and restoration of intra-renal autophagy. Graphical abstrac
