OCLC Number/Unique Identifier: 8691249258
Introduction: Uterine rupture is one of the peripartum complications, which cause nearly about one out of thirteen maternal deaths. This study aimed to assess the prevalence and associated factors of mortality among women with uterine rupture in referral hospitals of Lubumbashi, in the south east part of the Democratic Republic of Congo.
Methods: Institution based cross sectional study was conducted from December 1st, 2012 to 31st, 2016 on uterine rupture. During the study selected 158 women were included by using exhaustive sampling method. Data were checked, coded and analyzed into STATA version 12. Chi-square test was used to identify the predictors of maternal and perinatal mortalities in women with uterine rupture and 95% Confidence Interval of odds ratio at p - value less than 0.05 was taken as a significance level.
Results: The overall prevalence of uterine rupture was 0.49%. The average age of the patients was 29.5 ± 6.2 years and 71.52% of them were between 20 and 34 years old; more than 60% had a parity ≥4 (average parity: 4.7 ± 2.5). 81.17% of the cases had a fully ruptured uterus and 51.17% of the uterine ruptures were located in the lower segment. Repair of the pregnant ruptured uterus was performed in 93.04% of the cases and hysterectomy in 5.06%. Maternal and perinatal mortalities were 8.86% and 72.04% respectively. Regarding maternal mortality, no parameter showed a significant association with maternal death. As for perinatal mortality, parity ≥4, complete rupture and segmento-corporeal lesion were significantly associated with perinatal death (p < 0.05).
Conclusion: Uterine rupture remains one of the causes of maternal and perinatal mortality in Lubumbashi. The place occupied by uterine ruptures in obstetric activity requires joint and urgent action by all stakeholders in the health system in order to combat this scourge, witness to poor quality obstetric care.

Published on: 23rd March, 2017
OCLC Number/Unique Identifier: 7286429204
Introduction: Ankle sprain is a widespread impairment in sport groups; this impairment leads to an absence from the workplace. The ankle sprains incidence rates are induced by height, weight, BMI, physical fitness, level of match, classification of sport, and personal exposure to sport.
Methods: A longitudinal case-control study was executed to verify the outcome of risk factors for ankle sprain at a Military Male School between 2012 and 2013 of 4987 people at risk for ankle sprain, a total of 234 cadets sustained new ankle sprains during the study, 432 non-injured cadets randomly selected as the control group.
Results: Regarding to the total people at risk in our study the incidence rate was approximately 5/1000 ankle sprain-years. Cadets with ankle sprains had higher weight, BMI and higher scores in Army Physical Fitness test than the control group. Ankle sprain occurred most commonly during athletics (51.4%). Ankle sprain incidence rate did not significantly vary from different athletic competitions after controlling for athlete-exposure. Soccer and Ball Games had the highest ankle sprain incidence rate.
Conclusion: Higher weight, increased BMI, greater physical conditioning and athlete exposure to selected sports were all risk factors for ankle sprain.

The effects of storage of Ogbona seed flour (Irivingia gabonensis and Irivingia excelsa), at ambient condition (30±20C, 65-74% RH) for 0-4 months on some physical characteristics were investigated. The samples were subjected to storage in air tight polyethylene bags for up to four months. Samples were removed at intervals of 0, 1, 2, 3 and 4 months for analysis. The chemical: proximate constituents, free-fatty acids and peroxide values; selected functional properties: water/oil absorption capacity, foam capacity and viscosity and sensory attributes of the samples were investigated. The result shows that there was no observable change in the chemical composition, selected functional and sensory properties of the two varieties of Ogbona seed flours when stored up to two months but decreased from third to fourth month during storage at ambient temperature. Therefore, storage at ambient temperature (30±20C, 65-74% RH) could extend the shelf life of the samples for up to two months in air-tight polyethylene bags of 0.7mm thickness without losing its quality characteristics.

The study aimed to identify possible environmental risk factors for breast cancer among women in Gaza Strip and conducted in 2010. A case- control study design was used with face to face interviews by structured questionnaire with breast cancer patient women as well as healthy women. Statistical Package of Social Science (SPSS) was used to analyze the collected data. The study population was 288 women, 144 were women with breast cancer (cases) and 144 were healthy women (controls) with response rate 100% for cases as well as controls. The study was carried out in the two main hospitals in Gaza Strip (El-Shifa and European Gaza) and on cases who had a regular follow up in each hospital, while controls have been chosen from women who had no history of breast cancer by mammogram or by self-examination. In this study the main statistically significant risk factors were; marital status, educational status, physical trauma on breast, medication for infertility treatment, eating red meat 500g or more weekly, eating canned food, eating chicken skin, eating raw and cooked vegetables, using oils with saturated fats in cooking, living in or beside a farm, dealing with crops with naked hands, working in a farm during pesticides application or during 24 hours of pesticides application, cleaning pesticides’ equipment, living with people working in a farm or a agricultural field, and application of pesticides personally. In contrary, no statistically significant differences were found between cases and controls in relation to area of residency, exposure to X-ray in the past, having radiation therapy, getting contraceptive pills, using hair dyes, using anti-deodorant underarm, using facial cosmetics, using hair removal ointment, washing vegetables and fruits, buying and transporting pesticides, and wearing protective tools during pesticides mixing and application.

Internet has become an important part of our life, including during pregnancy where it is broadly used to find information (84%). The aims of this study were (1) to describe the proportion of women using Internet Social Networks (ISN) concerning their pregnancy, during pre or postpartum hospital stay, (2) to define how ISN users refer to their pregnancy and delivery on these social networks, (3) to compare anxiety level, social sustain level, sociodemographic characteristics of the both population (4) and to determine profiles of the ISN users with multiple correspondence analysis.
Methods: 399 questionnaires were distributed in the postpartum wards of two academic hospitals in Paris, and 258 fully filled were retrieved. Tools: Anxiety scale (STAI- A and B), Cutrona Social Provisions Scale, sociodemographic and obstetrical questionnaire.
Results: 76% (n = 195) were ISN users. We compared ISN users versus ISN non users women. Demographically, the two populations were comparable. Anxiety scores were similar in both groups, whereas social support scores showed a statistical difference in social integration.
In the global population, 84% use Internet for information concerning pregnancy; this rate is higher for ISN users than ISN non users (tendency 0.058).
ISN were used in priority for sharing with relatives, and 10% with other pregnant women. Concerning pregnancy, patients posted in priority the birth announcement (28%), the pregnancy announcement (23%), and the newborn’s pictures (12%). 6% posted their fetuses’ ultrasound pictures.
Three clusters of ISN users were extracted with statistically different social support scores (p = 0.019) and comparable anxiety scores. The third one, with at risk profile, used ISN as social support. For all women, but specifically for younger and more socially fragile women, Internet gives to professional new perspectives to develop information and prevention tools during the perinatal period.
Synergistic interactions of sperm impairing bacteria: Impact on pregnancy outcome in mouse model

Earlier in our laboratory, the role of various individual sperm impairing microorganisms on sperm parameters and female infertility has been elucidated at higher doses. As, multiple bacterial species tend to exert more pathogenic effect in comparison to single organism hence, present study was carried out to evaluate that if consortia of these sperm impairing organisms can lead to infertility in female mice at sub fertility dose. For this, impact of individual bacterial strains of Escherichia coli, Pseudomonas aeruginosa, Pseudomonas aeruginosa, Klebsiella pneumoniae and consortia of Escherichia coli and Pseudomonas aeruginosa, Escherichia coli and Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae was examined on the motility, viability of mouse spermatozoa and fertility outcome. The results showed that the individual bacterial strains of E. coli, S. marcescens and K. pneumoniae could led to immobilization of spermatozoa by agglutination and P. aeruginosa led to immobilization of spermatozoa without agglutination. Also, all of them led to 100% sperm death in 45 min of incubation. In case of consortia of bacterial strains, the results showed sperm agglutination in all the cases and they were able to induce 100% sperm death at 30 min of incubation time. Further, in vivo studies were carried out to evaluate the impact of individual bacterial strains and consortia of bacterial strains on the fertility outcome in female Balb/c mice. For this, female mice were administered intravaginally with 101 cfu/20µl of individual bacterial strains or consortia of strains for 10 consecutive days or PBS. The results showed that both individual bacterial strains and consortia of bacterial strains were able to efficiently colonize the mouse vagina. Further, control group receiving phosphate buffer saline and groups receiving individual bacterial strains showed all the pregnancy related changes viz. abdominal distension, string of pearls on palpation as well as delivery of pups on completion of gestation period and delivery of pups. The histological examination of reproductive organs viz. uterus and ovary, of the female mice receiving PBS or individual bacterial strains showed the formation of corpus luteum in the ovary and the formation of decidua’s in the uterus, indicative of pregnancy. However, mice receiving consortia of bacterial strains did not show any pregnancy related changes throughout the experiment. Thus, these results indicate that the presence of consortia of sperm impairing microorganisms in vaginal milieu is efficient in provoking infertility even at subfertility doses.

Following the COVID-19 proliferation beyond China’s borders at the beginning of 2020, containment measures have been taken by different countries around the globe. Citizens were forced to stay at home. Specifically, on March 19th, the Argentine Government decided to implement the “Social, preventive and mandatory isolation”, strategy that unfortunately impacts on the lifestyle, the practise of physical activity and on the nutritional aspect of the population. The aim of this study was analize eating habits and lifestyle changes during the COVID-19 lockdown on the 9 de Julio city, Bs. As., Argentina. The survey was conducted using Google Form. The questionnaire was divided into different sections: sociodemographic data, eating habits, physical activity and concepts and emotions associated with isolation. The research reached 287 responses with a medium socioeconomic level. During isolation, the frequency of purchases decreased. It was observed an increase in the consumption of pasta, bread and cakes. Concerning the physical activity, approximately 70% declared to train before the COVID-19 lockdown, decreased by 13% during the lockdown. Other activities conducted during the COVID-19 lockdown; the most mentioned were cleaning the house, cooking, watching television, series and movies. A percentage greater than 50% of the surveyed population associated the situation of lockdown with positive emotions (share with my family, stay at home); while only 24% associate it with negative emotions (anxiety, anguish, fear). It is expected that most habits will return to normal, however, it would be interesting to know which of those developed, adopted and implemented during lockdown will remain in the new normality.
A new applied protocol concerning COVID-19`s pandemic control: “Outdoor Access Approach” remodel of living for ensuring better ventilation

OCLC Number/Unique Identifier: 8872698405
COVID-19 is a mucoso-respiratory highly contagious disease that has leaded to a tremendous global pandemic wide spreading throughout nations of all continents with successive waves of high morbidities and mortalities. However, several independent vaccine production projects are working ahead for combatting the pandemic, but it is obvious they cannot create a sufficient umbrella that could protect billions of humans in a short term. Indeed, the current approved protocols including frequent cleaning of hands, social distancing and covering face mask are disappointing for their claimed capabilities to efficiently control of the pandemic. As they failed to highlight the critical determining role of air refreshing into indoors that 90 percent of infected people at least involved in enclosed spaces. Instead, Outdoor Access Approach (OAA) can be promising according veterinary medical successful experiences in control of air-borne contagious diseases as control of highly pathogenic avian influenza to become a global pandemic (One Health integration). Along with the above-mentioned protocols. Adaptation of all aspects of ordinary life activities in human societies to guarantee an efficient fresh air flow into enclosed spaces and prevention of the most dangerous air stagnation in them is the core stone of the OAA. This article discusses practical suggestions to attain such situation which can provide a kind of symbiosis with COVID-19` infection major threatening.
Risk of developing eating disorders through the misperception of the body image and the adoption of bad eating habits in a sample of young volleyball athletes
Published on: 8th March, 2021
OCLC Number/Unique Identifier: 8980363455
Objective: This preliminary study focused on the description of some dysfunctional perceptions of the body image and eating habits in a sample of young.
Methods: The results obtained by 55 amateur and professional volleyball players belonging to volleyball sports clubs located in the province of Reggio Emilia were examined. The age of the sample is in a range between 11 and 44 years. The participants completed the Pisa Survey for Eating Disorders (PSED), a questionnaire aimed at examining eating behavior and the perception of one’s body image. The athletes’ height and body weight were subsequently detected through direct measurement.
Conclusion: The data collected through the self-evaluation questionnaire and the measurements carried out by the study made it possible to analyze the perception of the body image and the eating habits of the volleyball players belonging to the sample and to compare them with the data in the literature. The data, albeit preliminary, allow us to confirm the existence of the discrepancy between the real body image and the desired one, in a group of young athletes, who favors the adoption of non-adaptive coping strategies to control one’s own weight and body shapes typical of the vicious circle - strict diet, bingeing episodes, compensatory behaviors - which characterizes eating disorders (ED). It is therefore considered essential that body image assessment is a practice implemented in the assessment routine of these athletes, especially in consideration of the fact that body image disturbance is a very common feature in this category and is one of the main risk factors of EDs.
Determinants of health seeking behaviour of women with obstetric fistula in south- south and south east, Nigeria: A review of the impact of availability and quality of health care services through a cross-sectional study
Published on: 4th May, 2021
OCLC Number/Unique Identifier: 9041186095
Background: Obstetric fistula is a condition that results from obstructed labour, which occurs when the baby cannot pass through the mother’s birth canal because it either does not come head first or is too large for her pelvis. Prompt medical intervention, often including Caesarean section, permits a safe delivery for both mother and child. Despite this possibility, yearly, thousands of women across the country receive no such aid and their labour is a futile agony lasting between three and five days, with uterine contractions constantly forcing the baby, usually head first, against the organs of the pelvic and unyielding pelvic bone resulting in Vesico Vaginal Fistula (VVF). The main thrust of this study was to examine how health system factors affect health seeking behaviour of women with obstetric fistula in Akwa Ibom and Ebonyi States, Nigeria.
Methods: Qualitative and descriptive research approaches were adopted for the study and a total sample of two hundred and sixteen (216) respondents comprising of one hundred and fifty (150) post fistula repair operative patients and sixty six (66) health workers were purposively selected using simple random techniques. The data were analyzed using thematic analysis and tables of frequency.
Results: The respondents views showed that availability of treatment centre and quality of health care services influenced health seeking behaviour of women with obstetric fistula in Nigeria.
Conclusion: The study indicated that health seeking behaviour of women with obstetric fistula is a major challenge in Nigeria. Establishment and proper equipment of obstetric fistula treatment centres as well as subsidization of the cost of treatment to allow women with this health problem to access health care services are strongly recommended. Therefore, government at all level and non-governmental organizations need to educate the women and create awareness on the causes and dangers of VVF.
Mild to moderate iodine deficiency in pregnancy: A matter of debate
Published on: 12th March, 2021
OCLC Number/Unique Identifier: 8980359493
During the last few decades painstaking efforts have been made to eliminate iodine deficiency through the world. Nowadays in regions where dietary iodine intake is adequate or borderline, the main focus is increasing dietary iodine supply in the target population during pregnancy and the first years of life. Severe iodine deficiency during pregnancy increases the risk of irreversible brain damage, intellectual disability, neurologic abnormalities, stunted growth, increased pregnancy loss, infant mortality, impairments in child development and cretinism. The potential effects of mild-to-moderate iodine deficiency are debated. Results from animal studies and observational human studies indicate that maternal mild-to-moderate iodine deficiency disturbs thyroid function in pregnancy and it also may affects fetal neurodevelopment. The effect of supplementation of iodine on thyroid function of pregnant women and their newborn, neurodevelopment of infants and cognitive performance of children have been investigated using iodine nutrition in pregnancy, based on median urinary iodine concentration. However they have found conflicting results regarding the benefits or harms of iodine supplementation in pregnancy. Although many epidemiological, interventional and clinical studies have supported the association between thyroid function in pregnant women and later psychomotor and mental development of their children, the effect of iodine supplementation in pregnant women on neurodevelopment of children is inconclusive. Even in areas with well-established universal salt iodization program, pregnancy could be at risk of having iodine deficiency and despite WHO/ICCIDD/UNICEF recommendation which believe that dietary iodine fortification during pregnancy depends primarily on the extent of pre-existing iodine deprivation, systematic dietary fortification needs to be implemented in this vulnerable group. However, iodine supplementation of mildly iodine deficient pregnant women may not have beneficial effects in their thyroid function or neurodevelopment of their children.
Pneumocephalus following labour epidural analgesia, a rare case report
Published on: 5th May, 2021
OCLC Number/Unique Identifier: 9041187138
The lumbar epidural analgesia is commonly used for labour analgesia. The “loss of resistance to air” LORA technique is commonly used for recognition of epidural space. One of the rare complications of this technique is Pneumocephalus (PC). We want to present a case of Pneumocephalus which the mother developed during epidural analgesia in labour. The patient complained of severe headache immediately after attempt at epidural catheter insertion. The symptoms progressively worsened following delivery. A postnatal anaesthetic review was performed and an urgent CT scan of the brain was arranged that showed pneumocephalus. A conservative management pathway was followed with liberal analgesia, oxygen inhalation and keeping the patient mostly in supine position. Her symptoms regressed in severity over the next three days and subsided after one week. We believe that the amount of air used for LORA should be minimized; LORA should not be used after dural puncture and the use of normal saline would alleviate the risk.
Factors associated with Female Genital Mutilation among daughters of reproductive aged women at Academic Charity Teaching Hospital (ACTH)
Published on: 11th June, 2021
OCLC Number/Unique Identifier: 9081421008
Introduction: It is estimated that more than 200 million girls and women alive today have undergone female genital mutilation. Female genital mutilation still remains to be a serious problem for large proportion of women in most sub-Saharan Africa countries including Sudan, with a high prevalence of 88%.
Objective: The main objective was to identify the factors associated with FGM among daughters of reproductive aged woman.
Materials and methods: A community based cross-sectional study was conducted on 200 mothers, the total sample was collected in ACTH based on the number of reproductive age mothers with at least one daughter older than 5 years. A structured and interviewer administered questionnaire was used to collect data. The data obtained was analyzed by the use of the SPSS software.
Results: Out of 200 mothers, 113 (56.5%) had at least one circumcised daughter. Knowledge about genital mutilation (AOR = 4.29, 95% CI: 1.13-15.37), attitude (AOR = 48.53, 95% CI: 14.45-198.69) and mothers circumcision status (AOR = 14.03, 95% CI: 2.81- 95.45) were the most significantly associated with FGM. Furthermore, having good knowledge, positive attitude, high socio-economic status, being literate, being of Christian religion and living in urban area had lower odds of having a circumcised daughter.
Conclusion: In this study, more than half of the mothers had at least one circumcised daughter. Mothers’ knowledge, attitude, circumcision status, socio-economic status, age, residence, educational level and religion were significantly associated with female genital mutilation.
The Femoral Head of Patients with Hip Dysplasia is not as Osteogenic as Iliac Crest Bone Location
Published on: 3rd January, 2017
OCLC Number/Unique Identifier: 7317655703
When Total Hip Arthroplasty (THA) is required in a patient with developmental dysplasia of the hip (DDH), bone deficiency in the acetabular roof often remains a problem. The iliac crest (IC) has long been the preferred source of autograft material, but graft harvest is associated with frequent complications and pain. Autologous bone graft can also be obtained from the femoral head (FH) for reconstruction of the acetabulum in hip arthroplasty. However, in certain challenging clinical scenarios, incorporation of the femoral head autograft appears less successful than the iliac crest autograft. The difference in potential for proliferation and osteoblastic differentiation between the two sites has still not been evaluated; therefore, it is not known how to compensate for this difference when it is present. We designed this study to evaluate the number of mesenchymal stem cells (MSCs) in both the iliac crest and femoral head of the same patient. We also determined the best operating room procedure for loading the femoral head with MSCs to achieve equivalent numbers of MSCs as in the IC. Twenty patients (8 men and 16 women) undergoing THA for DDH were enrolled in the study. The mean age was 55.5 years (range 41–65 years). Bone marrow aspirates were obtained from three depths within the femoral head and the aspirates were quantified relative to matched iliac crest aspirates that were obtained from the same patient at the same time. The cell count, progenitor cell concentration (cells/mL marrow), and progenitor cell prevalence (progenitor cells/million nucleated cells) were calculated.
Aspirates of FH marrow demonstrated less concentrations of mononuclear cells compared with matched controls from the iliac crest. Progenitor cell concentrations were consistently lower in FH aspirates compared to matched controls from the iliac crest (p = 0.05). The concentration of osteogenic progenitor cells was, on average, 40% lower in the FH aspirates than in the paired iliac crest samples (p = 0.05). However, with bone marrow aspirated from the iliac crest, we were able to load the femoral head autograft with sufficient MSCs to obtain the same number as present in an iliac crest. With concentrated bone marrow from the IC, supercharging the femoral autograft with MSCs to numbers above that present in the IC was possible in the operating room, and the number of MSCs supercharged in the femoral head was predictable.
Based on these findings we suggest that FH graft supercharged with BM-MSCs from the IC is comparable to IC graft for osseous graft supplementation especially in THA for patients with DDH.
Enhancing adipose stem cell chondrogenesis: A study on the roles of dexamethasone, transforming growth factor β3 and ascorbate supplements and their combination
Published on: 31st July, 2017
OCLC Number/Unique Identifier: 7317597470
Varied exogenous chondrogenic factors (CFs) are implicated in promoting differentiation of stem cells along a chondrocyte lineage in the field of regenerative tissue engineering for articular cartilage repair. The effects of dexamethasone, transforming growth factor β3 (TGF-β3), ascorbate, and their combinations, on mRNA expression in micromass-cultured human adipose derived stem cells (hADSCs) were investigated as a function of time. Indices include chondrogenic, hypertrophic, angiogenic, fibrogenic and osteogenic markers along with mechanical properties, assessed by atomic force microscopy. Early in the culture, i.e., at day three, no significant differences in mRNA expression of SOX9, aggrecan, lubricin, Col XI, Col X, vascular endothelial growth factor, Col I, and alkaline phosphatase were observed among samples treated with different CFs. However, significant differences in mRNA expression levels of pre-mentioned markers among samples treated with each CF exist when samples were supplied with the CFs for more than three days. A new indexing scheme summing expression of chondrogenic and subtracting non-chondrogenic angiogenic, fibrogenic and osteogenic marker levels shows dexamethasone is the overall leading CF among the factors and their combinations. Based on this scheme, we have projected not only the possible signaling pathways which might be affected by addition of CFs but also hypothetical indexes that may occur upon temporal variation of growth factor regimens.
A flow perfusion bioreactor with controlled mechanical stimulation: Application in cartilage tissue engineering and beyond
Published on: 13th June, 2018
OCLC Number/Unique Identifier: 7815003397
To repair articular cartilage (AC) defects in osteoarthritic patients, one approach is to engineer three-dimensional grafts with physicochemical properties similar to endogenous AC. Such grafts can be grown in bioreactors that provide environmental conditions favoring chondrogenesis. Studies show mechanical stimulation during the culturing process greatly enhances development of functional engineered grafts. A review of literature on bioreactor options reveals a lack of capacity to simultaneously stimulate cells with a combination of shear stress and oscillating hydrostatic pressure, both of which are important parts of the in vivo AC environment. It is hypothesized that combining both forces in a new bioreactor design will contribute to better AC tissue growth. In this paper, we provide a brief review of bioreactors and describe a new computer-controlled perfusion and pressurized bioreactor system, and the novelty of its control programming features for service in a host of applications. We briefly summarize results on synergistic effects in employing perfusion, oscillating hydrostatic pressure in a scaffold free environment and with the addition of encapsulation for inducing chondrogenesis. We further describe efforts to modify the newly developed system to include a continuous flow and pressurized centrifugal mode to enhance further the capabilities for inclusion of very high shear stresses. Applications for several other cell and tissue engineering approaches are discussed.
Knowledge, attitude and motivation toward stem cell transplantation and donation among Saudi population in Riyadh: Are Saudi people aware enough about the importance of stem cell transplantation and donation?
Published on: 13th November, 2020
OCLC Number/Unique Identifier: 8873218106
Objectives: The aim of this study was to assess the knowledge, attitude and motivation toward stem cell donation among Saudi population in Riyadh, Saudi Arabia.
Methods: This is a cross-sectional study that was conducted at different malls in Riyadh. Selection of malls was done randomly according to the geographical distribution of Riyadh, in which sample size was calculated and distributed equally. The participants were asked to complete a questionnaire that addressed their knowledge, attitude and motivation toward stem cell transplantation and donation.
Results: Results of this study showed that population knowledge about stem cell transplantation and donation is considered to be low. Only (37.8%) has enough information about stem cell transplantation and donation. There is a positive correlation between level of education and participant’s knowledge regarding stem cell transplantation and donation. The study revealed that 39.3% of participants have willingness for stem cell donation.
Conclusion: It has been found that two third of population expressed lack of knowledge about stem cell transplantation and donation. Also, only 40% of participants showed willingness for donation, and the most common reason for not donating stem cell was the lack of information about stem cell and the value of donation While, increasing level of education was associated with better understanding of stem cell donation and its role in therapy and saving lives. Therefore, suitable campaign, advertising and counseling program for population is recommended to increase level of knowledge and motivation toward stem cell donation.
The pattern of blood pressure and renal function among children with Sickle Cell Anaemia presenting in a tertiary health institution in Nigeria
Published on: 16th April, 2019
OCLC Number/Unique Identifier: 8163611724
Background: In sickle cell anemia (SCA), compromise of the renal vasculature due to sickled red cells has been recognized.
Objectives: To assess the renal function and blood pressure pattern in children with sickle cell anaemia (SCA) presenting in a tertiary institution.
Method: A cross-sectional study of patients with sickle cell anaemia (SCA) over six months involving the use of questionnaires, general physical examination, blood pressure, investigations for haemoglobin genotype, urinalysis, serum creatinine, screening for hepatitis B and HIV.
Results: 51 children with SCA were seen. The prevalence of impaired renal function as defined by reduced eGFR <90mL/min/1.73m2 in this study was 27.5%, previous hospital admission and blood transfusion were associated with reduction in eGFR but blood pressure did not have significant correlation with the eGFR. The overall mean age at diagnosis of SCA was 4.09 ± 3.33 (years).
Conclusion: Impaired renal function is a major comorbid condition in children with SCA. In countries/locations where there is no newborn screening for sickle cell disease, diagnosis is delayed, thus detecting impaired renal function may be delayed, therefore the need for early detection and management is imperative.Introduction
Varicella zoster virus: The potentially useful virus
Published on: 5th July, 2019
OCLC Number/Unique Identifier: 8174826530
Varicella zoster virus (VZV), a double-stranded DNA virus, is a highly contagious human neurotropic virus that belongs to the alpha group of herpes viruses [1-4]. Primary VZV infection (chickenpox) occurs in childhood then the virus becomes latent in the nerve ganglia [1,5-7]. Reactivation of the virus may occur decades later and cause herpes zoster (HZ) which is manifested by a typical painful skin eruption that has characteristic dermatomal distribution [1,5]. Reactivation of VZV is usually predisposed to: old age; comorbid medical conditions such as diabetes mellitus, chronic obstructive airway disease, and end-stage renal disease; and immunosuppression due to malignancy, autoimmune disorders, immunosuppressive therapies, trauma, cytotoxic chemotherapy, hematopoietic stem cell transplantation (HSCT), and solid organ transplantation (SOT) [1,5-7].

This is to specify that I have had an extensive and detailed interaction with the Editorial team of Annals of Clinical Gastroenterology and Hepatology, USA, lasting over a significant period of time. My interaction has been extremely pleasant, especially with Ms Allie Smith, as I find the communication quite inspiring and crystal clear. The attitude of aforesaid individuals is quite helpful and guiding in pertinent instances. It has been a commemorative journey so far working with the Journal and I hope that the symbiosis will continue, evolve and flourish in the forthcoming years. I wish the journal, related personnel and aforementioned individuals a fruitful, successful run.

Publishing with the International Journal of Clinical and Experimental Ophthalmology was a rewarding experience as review process was thorough and brisk. Their visibility online is second to none as their published articles appear in all search engines. I will encourage researchers to publish with them.
