Nanomaterials in Drug Delivery: Strengths and Opportunities in Medicine.

There is a myriad of diseases that plague the world ranging from infectious, cancer and other chronic diseases with varying interventions. However, the dynamism of causative agents of infectious diseases and incessant mutations accompanying other forms of chronic diseases like cancer, have worsened the treatment outcomes. These factors often lead to treatment failure via different drug resistance mechanisms. More so, the cost of developing newer drugs is huge. This underscores the need for a paradigm shift in the drug delivery approach in order to achieve desired treatment outcomes. There is intensified research in nanomedicine, which has shown promises in improving the therapeutic outcome of drugs at preclinical stages with increased efficacy and reduced toxicity. Regardless of the huge benefits of nanotechnology in drug delivery, challenges such as regulatory approval, scalability, cost implication and potential toxicity must be addressed via streamlining of regulatory hurdles and increased research funding. In conclusion, the idea of nanotechnology in drug delivery holds immense promise for optimizing therapeutic outcomes. This work presents opportunities to revolutionize treatment strategies, providing expert opinions on translating the huge amount of research in nanomedicine into clinical benefits for patients with resistant infections and cancer.

Reversible inter-degree-of-freedom optical-coherence conversion via entropy swapping.

The entropy associated with an optical field quantifies the field fluctuations and thus its coherence. Any binary optical degree-of-freedom (DoF) - such as polarization or the field at a pair of points in space - can each carry up to one bit of entropy. We demonstrate here that entropy can be reversibly swapped between different DoFs, such that coherence is converted back and forth between them without loss of energy. Specifically, starting with a spatially coherent but unpolarized field carrying one bit of entropy, we unitarily convert the coherence from the spatial DoF to polarization to produce a spatially incoherent but polarized field by swapping the entropy between the two DoFs. Next, we implement the inverse unitary operator, thus converting the coherence back to yield once again a spatially coherent yet unpolarized field. We exploit the intermediate stage between the two coherence conversions - where the spatial coherence has been converted to the polarization DoF - to verify that the field has become immune to the deleterious impact of spatial phase scrambling. Maximizing the spatial entropy protects the spatial DoF by preventing it from taking on any additional fluctuations. After the second coherence conversion, spatial coherence is readily retrieved, and the effect of spatial phase scrambling circumvented.

Modeling, optimization, and validation of an extended-depth-of-field optical coherence tomography probe based on a mirror tunnel.

The diagnostic capability of high-resolution optical coherence tomography (OCT) may be enhanced by using extended depth-of-field (EDOF) imaging that retains high transverse resolution over long depths. A recently developed mirror-tunnel optical probe design (single-mode fiber to multimode fiber to lens structure) that generates coaxially focused modes has been previously shown to enable EDOF for endoscopic OCT applications. Here, we present ray-tracing optical modeling of this optical configuration, which has the potential to guide performance improvement through optimization. The Huygens wave propagation of the field was traced through probe components with initial lengths. The irradiance along the x-z plane was analyzed, yielding an average full width at half-maximum (FWHM) of 9 µm over a 640 µm DOF (defined as the axial range over which the beam's transverse FWHM is maintained). A custom merit function was then defined, based on the focal region illumination intensity profile that yielded the maximum possible depth having a constrained FWHM size. An orthogonal gradient descent optimization algorithm was then applied using this merit function, using the multimode fiber, spacer, and lens lengths as variables. Optimization resulted in a modeled mean 6 µm FWHM spot diameter over an EDOF of 1 mm. Following optimization, a probe was fabricated, and was validated using a custom-built near-field scanning pinhole beam profiler. The experimental results (6 µm mean FWHM over 800 µm EDOF) showed reasonable correspondence to the simulated predictions, demonstrating the potential utility of optical modeling and optimization for improving EDOF performance in mirror-tunnel endoscopic OCT probes.

Randomized control trial on effectiveness and safety of direct trocar versus Veress needle entry techniques in obese women during diagnostic laparoscopy.

PURPOSE: To determine the benefits and safety of direct trocar insertion versus Veress needle technique in obese women undertaking diagnostic laparoscopy procedures. METHODS: Randomized-controlled trial on 135 obese women undergoing diagnostic laparoscopy and dye test for infertility was conducted. Women were randomly assigned to either direct trocar access (n = 68) or Veress needle access (n = 67) before achieving pneumoperitoneum. The same surgeon executed the laparoscopic techniques with a single-puncture technique. The primary outcome measures included total length of the procedure and incidence of any complications, while the mean laparoscopic entry time, volume of CO2 required, and total of tries needed to attain successful entry were secondary outcomes. Intention-to-treat principle was applied to analysis. RESULTS: Women in both groups had similar socio-demographic and clinical characteristics and none were lost to follow-up. The overall length of the procedure was significantly lesser in the direct trocar group compared to the Veress needle group (9.9 ± 6.0 vs 16.7 ± 4.7 min; p < 0.001). No significant differences occurred in other outcomes including mean entry time, volume of CO2 used, number of attempts for successful entry, and major/minor complications (p > 0.05). CONCLUSIONS: Direct trocar technique may be an effective alternative to Veress needle for pneumoperitoneum in obese women for diagnostic laparoscopy. It has a comparable rapid laparoscopic entry time but a significantly lower duration of the procedure and shorter exposure to anesthesia. Both methods are equally effective as there was no significant difference in the complications recorded. A greater sample trial may be essential for more corroborative substantiation.

Ginger juice prevents cisplatin-induced oxidative stress, endocrine imbalance and NO/iNOS/NF-κB signalling via modulating testicular redox-inflammatory mechanism in rats.

The off-target testicular toxicity of the anticancer drug, cisplatin, is a current clinical concern and worrisome to male cancer patients. Growing evidence has implicated oxidative stress and inflammation in cisplatin toxicity. We have explored whether fresh ginger juice could mitigate testicular toxicity induced by anticancer drug cisplatin in rats. Rats were subjected to oral administration of fresh ginger juice (5 ml/kg body weight/day) for 5 days against testicular damage induced by single ip injection of cisplatin (CIS) (10 mg/kg body weight) on day 2 only. Testicular activities of antioxidant enzymes, malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NO), inflammatory cytokines, inducible nitric oxide synthase (iNOS) and nuclear factor-ĸB (NF-ĸB) and serum hormone levels were estimated. CIS-induced prominent decreases in antioxidant enzyme activities, GSH and serum hormone levels, whereas levels of MDA, cytokines, NO, iNOS and NF-ĸB increased remarkably (p < .05) compared to control. Interestingly, the CIS-induced testicular alterations were considerably mitigated by the fresh ginger juice via abrogation of oxidative stress and anti-inflammatory mechanism. The study suggests, for the first time, antioxidant and anti-inflammatory effects of ginger juice against CIS testicular damage. Fresh ginger juice may have beneficial health impact on testicular side effect of CIS chemotherapy.

Impact of early versus delayed umbilical cord clamping on term neonates' haemoglobin levels: a randomized controlled trial.

OBJECTIVE: To compare the effects of early and delayed cord clamping on the haemoglobin levels of neonates delivered at term. METHODS: This randomized controlled trial enrolled pregnant women during the second stage of labour. They were randomized into either the early cord clamping (ECC) group or the delayed cord clamping (DCC) group in the ratio of 1:1. Following delivery of the baby, the umbilical cords of participants in the ECC group were clamped within 30 s of delivery of the neonate while those of participants in the DCC group were clamped after 2 min from the delivery of the neonate. The primary outcome measure was the effect of ECC and DCC on the haemoglobin levels of neonates delivered at term. RESULTS: A total of 270 pregnant women were enrolled in the study. Their baseline sociodemographic and clinical characteristics were similar in both groups. There was no significant difference in the mean haemoglobin level between ECC and DCC groups at birth. The mean haemoglobin level of the neonates at 48 h postpartum was significantly higher in the DCC group than the ECC group. CONCLUSION: DCC at birth was associated with a significant increase in neonatal haemoglobin levels at 48 h postpartum when compared with ECC.Trial Registration: The trial was registered at Pan African Clinical Trial Registry with approval number PACTR202206735622089.

Association between serum vitamin D status and uterine leiomyomas: a case-control study.

OBJECTIVE: Uterine leiomyoma is a common gynecological condition that negatively affects women's quality of life. Vitamin D plays an important role in tumor development and progression. However, clinical studies comparing serum vitamin D levels between women with and without uterine leiomyomas are limited and inconclusive. This study aimed to compare serum vitamin D levels in women with and without uterine leiomyomas. METHODS: This hospital-based case-control study included 150 women who visited a gynecological clinic. The cases included 75 women with uterine leiomyoma, whereas the controls included 75 age-and parity-matched participants without uterine leiomyoma. Serum vitamin D levels were measured in each participant and volumes of the uterine leiomyomas were determined using the water displacement method following myomectomy. The statistical significance was inferred at P<0.05. RESULTS: The mean serum vitamin D level was 15.26±4.96 ng/mL and 22.45±6.93 ng/mL for the case and control groups, respectively. The difference was statistically significant (t-value -7.302 and P<0.001). Within the fibroid group, nine (12.0%), 49 (65.33%), and 17 (22.67%) participants had vitamin D deficiency, insufficiency, and sufficiency, respectively; and in the control group, two (2.67%), 24 (45.33%), and 39 (52.0%) participants had vitamin D deficiency, insufficiency, and sufficiency, respectively. There was significant negative correlation between the fibroid volume and the serum vitamin D level (r=-0.591, P<0.001). CONCLUSION: Women with uterine leiomyoma had lower vitamin D levels than women in the control group. Lower vitamin D levels were associated with larger fibroid masses. Therefore, vitamin D supplementation may reduce fibroid growth and development.

Double true umbilical cord knots coexisting with a nuchal cord with successful fetal outcome: A case report.

Umbilical nodes and cords play a crucial role in fetal development and are essential for the transfer of nutrients and oxygen between the mother and the fetus. Sonographic diagnosis of umbilical nodes and cords has become an integral part of prenatal care, allowing for the early detection of abnormalities and potential complications. The umbilical cord is a vital structure connecting the fetus to the placenta, providing essential nutrients and oxygen for fetal growth and development. Sonographic examination of the umbilical cord and its associated nodes has become an indispensable tool in prenatal care, enabling the early detection of abnormalities and potential complications. This review aims to analyze the current literature on sonographic diagnosis of umbilical nodes and cords, highlighting the key points and advancements in this field. A 37-year-old booked G4P2+1A2 Nigerian woman was registered for prenatal tertiary health care at 12 weeks of gestation. The booking investigations were normal and the booking packed cell volume was 37%. She was compliant with scheduled clinic visits and routine drugs. Pregnancy was carried to term uneventfully. Elective cesarean section was successfully performed at 38 weeks of gestation owing to the patient's prior history of third-degree perineal tear. The intraoperative findings included a loose cord around the neck of the baby and double true knots along the length of the 65 cm umbilical cord. The baby was delivered with appearance, pulse, grimace, activity and respiration (APGAR) scores of 7 in the first minute, 9 in the fifth minute, and the birth weight was 3.0 kg. Mother and baby were discharged 48 h postpartum in stable clinical condition. Although the presence of true double umbilical knots is rare, its coexistence with the nuchal cord is even rarer. There are risk factors associated with true umbilical knots. The possible risk factor implicated in this index case is the gender of the fetus and maternal multiparity. True umbilical knots are usually associated with certain fetal negative outcomes of pregnancy. There are currently no evidence-based treatment options available.

Carpal fractures, dislocations, special radiographic views, and imaging pearls will be discussed. Instability patterns and the myriad of associate abbreviations (CID, CIND, CIC, CIA, VISI, DISI, SLD, LTD, MCI, SLAC, SNAC) will be clarified. Expected outcomes, potential complications, and management will be reviewed.

Effect of Educational Intervention Program on Self-Efficacy of Individuals with Type 2 Diabetes Mellitus in South-East, Nigeria.

Objectives: Diabetes Mellitus is a chronic disease, which requires a level of confidence among the sufferers in its management. This study investigated the effect of an educational intervention program on self-efficacy (SE) in diabetic individuals with type 2 diabetes mellitus in South-East, Nigeria. Methods: The study was a quasi-experimental controlled study, comprising 382 individuals with type 2 DM selected, and assigned to intervention (IG) and control groups (CG). The instrument for data collection was the Stanford Chronic Disease Self-Efficacy Scale (SCDS). Pretest data were collected, and thereafter education on diabetes management was given to the IG group. The IG was followed up for 6 months. At the end of 6 months, post-test data were collected using the same instrument. Data were analyzed using Pearson Chi-square test statistics. A P-value less than .05 alpha level was considered significant. Results: There was no statistically significant difference between the two groups before intervention. However, after 6 months of intervention, a significant proportion of participants' scores in IG moved from low to either moderate, or high SE in almost all the SE domains (P < .05. Conclusions: There was an improvement in most domains of self-efficacy in the intervention group after 6 months of educational intervention.

Efficacy of zinc supplementation for the treatment of dysmenorrhoea: a double-blind randomised controlled trial.

OBJECTIVES: To determine the efficacy of zinc sulfate supplementation in managing dysmenorrhoea. METHODS: In total, 103 high school students were randomised into an experimental arm (52 students) and a control arm (51 students) and received 40-mg zinc sulfate or placebo, respectively, over three cycles. Primary outcome measures were the mean Visual Analogue Scale score, which measured pain over three cycles, and the frequency of nausea and vomiting. Secondary outcomes were the use of additional analgesics and the frequency of allergic reactions. RESULTS: Fifty participants were analysed in each group. Mean pain scores were not significantly different between the groups before administering zinc sulfate therapy. Following the intervention, the mean pain scores for the treatment (2.80 ± 2.28) and placebo (3.48 ± 2.85) groups were not significantly different in the first cycle; however, scores in the treatment group were significantly better in the second (2.56 ± 1.97 vs 3.80 ± 2.77) and third (1.95 ± 1.72 vs 3.95 ± 2.82) cycles. No significant differences were observed between the groups in the nausea and vomiting incidence and the requirement for additional analgesics. CONCLUSIONS: Zinc sulfate reduces dysmenorrhoea severity with minimal or no adverse effects, especially with more than one cycle of usage.Trial Registration Number: PACTR202105843292338. The trial is publicly available and was registered at www.pactr.org on 25 May 2021.

Intra-operative Diagnosis of Lower Segment Scar Dehiscence in a Second Gravida After One Previous Lower Segment Cesarean Section: Should We Advocate for Routine Antenatal Uterine Scar Thickness Testing?

Background: Uterine dehiscence is a separation of uterine musculature with intact uterine serosa. It can be encountered at the time of cesarean delivery, suspected on obstetric ultrasound or diagnosed in-between pregnancies. The antenatal diagnosis may occasionally elude the Obstetricians. This particular case demonstrates an intra-operative diagnosis of uterine dehiscence with missed antenatal ultrasound diagnosis in an asymptomatic woman. Case presentation: She was a 32-year-old Nigerian second gravida who booked for antenatal care at 32 weeks of gestation following a referral from her attending Obstetrician from a neighboring state due to relocation. She had 3 antenatal visits and 2 antenatal ultrasound investigations without uterine scar thickness report. She subsequently had elective Cesarean section (CS) at a gestational age of 38 weeks plus 2 days due to persistent breech presentation on a background of a previous lower segment CS scar. There was no previous uterine curettage prior to or after the previous lower segment CS scar and there was no labor pains prior to the elective CS. The surgery was successful with intra-operative findings of moderate intra parietal peritoneal adhesions with rectus sheath and obvious uterine dehiscence along the line of the previous CS scar. The fetal outcomes were normal. Immediate post-operative condition was satisfactory and the woman was discharged on a third-day post operation. Conclusion: Obstetricians are charged to maintain a high index of suspicion when managing pregnant women with history of emergency CS in order to avert the adverse consequences of uterine rupture from asymptomatic uterine dehiscence. Based on this report, it may be useful to routinely assess the lower uterine segment scar of women with previous emergency CS using the available ultrasound facilities. However, more studies are needed before advocating for routine antenatal uterine scar thickness testing following emergency lower segment CS in low and middle-income settings.

Obstetric Outcome of Induction of Labour in a Tertiary Hospital in Nigeria: A Five-Year Retrospective Cross-Sectional Study.

Background: Induction of labour has remained one of the most valuable interventions in obstetric practice. Over the years, the proportion of women undergoing induction of labour (IOL) has been on a steady increase. The significance to obstetrics practice as well as its maternal and perinatal outcomes are sacrosanct, hence the need for its periodic review. Objective: To determine the obstetric outcomes of induction of labour. Methods: A five-year retrospective study of all cases of induction of labour at the maternity unit of Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Nigeria between January 1st 2017 and 31st December 2021. The labour ward's records were assessed to determine the total number of women who had induction of labour during the study period. Women whose case files could be not retrieved were excluded. The folder numbers of the patients were extracted and their case files retrieved from the medical records department of the hospital. The primary outcomes measures were the indications and the methods of induction of labour, while the secondary outcome measures were the mode of delivery, cause of failed induction, and the perinatal outcome. Data were obtained using proformas and analysed using statistical packages for social sciences (SPSS) version 26.0 IBM corporation. Result: A total of 3,638 deliveries were taken during the period under review and 168 patients had induction of labour giving an overall prevalence of 4.6% (46/1000 deliveries). Induction of labour was successful in 71.2% of cases. Misoprostol was used in 90.4% of cases as an induction agent. The commonest indication for induction of labour was postdate pregnancy (53.8%). Failed induction was due to fetal distress, poor progress of labour from cephalopelvic disproportion/malposition and failed cervical ripening. In about 72% of deliveries, there was good perinatal outcome, 10.3% of babies had moderate to severe asphyxia while 1.3% had neonatal death. Conclusion: Induction of labour is a safe and beneficial procedure in obstetrics. However, it can be associated with adverse obstetric outcomes.

Challenges of Management of Ruptured Second Trimester Ovarian Pregnancy in Low-and Middle-Income Settings: A Case Report.

Background: Ovarian ectopic pregnancy is a rare form of non-tubal ectopic pregnancy. It can rupture before the end of the first trimester, causing hemoperitoneum, and present with signs and symptoms similar to other commoner abdominal emergencies or the pregnancy can continue intraperitoneally. Therefore, they are not often diagnosed preoperatively. Ultrasound can assist in diagnosis of ovarian ectopic pregnancy but the findings could be ambiguous or inconclusive. We present a case of ruptured ovarian ectopic pregnancy at the second trimester causing massive hemoperitoneum that was suspected as an intrabdominal malignancy co-existing with intrabdominal pregnancy. Case presentation: She was a 34 year-old Nigerian unbooked G4P3+0, (3 alive), who presented to the labor ward on 21st January, 2021 with a complaint of a 6-week history of abdominal pain and swelling. Pain was insidious in onset, generalized, non-colicky, non-radiating, constant, no known aggravating or relieving factor, but it was of moderate intensity. She had amenorrhea with a positive serum pregnancy test without prior early ultrasound. At presentation, initial abdominopelvic ultrasound revealed intra-uterine viable pregnancy but repeat ultrasound done showed a left adnexal ectopic gestation and an echo-rich intraperitoneal fluid collection. Laparotomy was done and ovarian pregnancy was accurately diagnosed intra-operatively. Tissue samples from the ovary confirmed normal products of conception, namely chorionic villi, trophoblastic cells and ovarian stroma at histology. Conclusion: Despite advances in imaging techniques, the diagnosis of ovarian ectopic gestation is still very difficult. When premenopausal women present with amenorrhea, generalized non-colicky abdominal pain and swelling in combination with ambiguous findings of pregnancy on ultrasound in the absence of trauma, differential diagnoses should include ruptured ovarian pregnancy. Obstetricians should maintain a high index of suspicion to forestall delayed diagnosis and the potential maternal morbidity and mortality. However, the need for high-index of suspicion should be for any ectopic, not just ovarian pregnancy.

A randomized clinical trial of Premaquick biomarkers versus transvaginal cervical length for pre-induction cervical assessment at term among pregnant women.

Objectives: To compare Premaquick biomarkers (combined insulin-like growth-factor binding protein 1 and interleukin-6) and cervical length measurement via transvaginal ultrasound for pre-induction cervical evaluation at term among pregnant women. Methods: A randomized clinical trial of consenting pregnant women at the Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria. The women were randomized equally into Premaquick group (n = 36) and transvaginal ultrasound group (n = 36). The cervix was adjudged 'ripe' if the Premaquick test was positive or if the trans-vaginal measured cervical length was less than 28 mm. The primary outcome measures were the proportions of women who needed prostaglandin analogue for cervical ripening and the proportion that achieved vaginal delivery after induction of labour. The trial was registered in Pan African clinical trial registry (PACTR) registry with approval number PACTR202001579275333. Results: The baseline characteristics were similar between the two groups (p > 0.05). There was no statistically significant difference between the two groups in terms of proportion of women that required prostaglandins for pre-induction cervical ripening (41.7 versus 47.2%, p = 0.427), vaginal delivery (77.8 versus 80.6%, p = 0.783), mean induction to delivery interval (22.9 ± 2.81 h versus 24.04 ± 3.20 h, p = 0.211), caesarean delivery (22.2 versus 19.4%, p = 0.783), proportion of neonate with birth asphyxia (8.30 versus 8.30%, p = 1.00) and proportion of neonate admitted into special care baby unit (16.7 versus 13.9%, p = 0.872). Subgroup analysis of participants with 'ripe' cervix at initial pre-induction assessment showed that the mean induction to active phase of labour interval and mean induction to delivery interval were significantly shorter in Premaquick than transvaginal ultrasound group. Conclusion: Pre-induction cervical assessment at term with either Premaquick biomarkers or transvaginal ultrasound for cervical length is effective, objective and safe with similar and comparable outcome. However, when compared with women with positive transvaginal ultrasound at initial assessment, women with positive Premaquick test at initial assessment showed a significantly shorter duration of onset of active phase of labour and delivery of baby following induction of labour.

A Systematic Review and Meta-Analysis of the Prevalence of Triplex Infections (Combined Human Immunodeficiency Virus, Hepatitis B Virus, and Hepatitis C Virus) among Pregnant Women in Nigeria.

Objective: We systematically identified the prevalence of triplex infections (combined human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV)) in pregnancy. Methods: To gather information on the frequency of triplex infections, we searched the databases of PubMed, CINAHL, and Google Scholar. Without regard to language, we utilized search terms that covered HIV, HBV, HCV, and pregnancy. Pregnant women with triplex infections of HIV, HBV, and HCV were included in studies that also examined the prevalence of triplex infections. Review Manager 5.4.1 was employed to conduct the meta-analysis. Critical appraisal and bias tool risk data were provided as percentages with 95% confidence intervals (95% CIs), and I2 was used as the statistical measure of heterogeneity. The checklist was created by Hoy and colleagues. The study protocol was registered on PROSPERO, under the registration number CRD42020202583. Results: Eight studies involving 5314 women were included. We identified one ongoing study. Pooled prevalence of triplex infections was 0.03% (95% CI: 0.02-0.04%) according to meta-analysis. Subgroup analysis demonstrated a significantly high prevalence of 0.08% (95% CI: 0.06-0.10%; 3863 women) in HIV-positive population than 0.00% (95% CI:-0.00-0.00; 1451 women; P < 0.001) in general obstetric population. Moreover, there was a significant difference in the pooled prevalence between studies published between 2001 and 2010 and between 2011 and 2021 (0.14% (95% CI: 0.12 to 0.16 versus 0.03% (95% CI: 0.02 to 0.04%; P < 0.001))) and participants recruited in the period between 2001 and 2011 and between 2012 and 2021 (0.13% (95% CI: 0.05 to 0.21; p=0.002 versus 0.00% (95% CI: -0.00 to 0.00%; p=1.00))), respectively. Conclusion: The combined prevalence of prenatal triplex infections was 0.03%, with rates notably higher among the group of pregnant women who were HIV-positive and during the recruitment period that took place before 2012. This prevalence still necessitates screening for these infections as necessary.

Efficacy and safety of Mojeaga remedy in combination with conventional oral iron therapy for correcting anemia in obstetric population: A phase II randomized pilot clinical trial.

BACKGROUND: To our knowledge, there is no prior randomized trial on the efficacy of Mojeaga remedy (a special blend of Alchornea cordifolia, Pennisetum glaucum and Sorghum bicolor extracts) when co-administered with standard-of-care for correction of anemia in obstetrics practice. This study determined the efficacy, safety and tolerability of Mojeaga as adjunct to conventional oral iron therapy for correction of anemia in obstetric population. METHODS: A pilot open-label randomized clinical trial. Participants with confirmed diagnosis of anemia in three tertiary hospitals in Nigeria were studied. Eligible participants were randomized 1:1 to either Mojeaga syrups 50 mls (200mg/50mls) administered three times daily in conjunction with conventional iron therapy (Mojeaga group) for 2 weeks or conventional iron therapy alone without Mojeaga (standard-of-care group) for 2 weeks. Repeat hematocrit level were done 2 weeks post-initial therapy. Primary outcome measures were changes in hematocrit level and median hematocrit level at two weeks post therapy. Maternal adverse events and neonatal outcomes (birth anomalies, low birthweight, preterm rupture of membranes and preterm labor) were considered the safety outcome measures. Analysis was by intention-to-treat. RESULTS: Ninety five participants were enrolled and randomly assigned to the Mojeaga group (n = 48) or standard-of-care group (n = 47). The baseline socio-demographic and clinical characteristics of the study participants were similar. At two weeks follow-up the median rise in hematocrit values from baseline (10.00±7.00% vs 6.00±4.00%;p<0.001) and median hematocrit values (31.00±2.00% vs 27.00±3.00%;p<0.001) were significantly higher in the Mojeaga group. There were no treatment-related serious adverse events, congenital anomalies or deaths in the Mojeaga group and incidence of other neonatal outcomes were similar (p>0.05). CONCLUSION: Mojeaga represents a new adjuvants for standard-of-care option for patients with anemia. Mojeaga remedy is safe for treating anemia during pregnancy and puerperium without increasing the incidence of congenital anomalies, or adverse neonatal outcomes.

The impact of COVID-19 on the birth rate in Nigeria: a report from population-based registries.

Background and objectives: Coronavirus disease 2019 (COVID-19) is a pandemic that has become a major source of morbidity and mortality worldwide, affecting the physical and mental health of individuals influencing reproduction. Despite the threat, it poses to maternal health in sub-Saharan Africa and Nigeria, there is little or no data on the impact it has on fertility, conception, gestation and birth. To compare the birth rate between pre-COVID and COVID times using selected months of the year. Materials and methods: This was a secondary analysis of cross-sectional analytical study data from the birth registries of three tertiary hospitals, comparing two years [2019 (Pre-COVID)] versus [2020 (COVID era)] using three months of the year (October to December). The data relied upon was obtained from birth registries in three busy maternity clinics all within tertiary hospitals in South-East Nigeria and we aimed at discussing the potential impacts of COVID-19 on fertility in Nigeria. The secondary outcome measures were; mode of delivery, booking status of the participants, maternal age and occupation. Results: There was a significant decrease in tertiary-hospital based birth rate by 92 births (P = 0.0009; 95% CI: -16.0519 to -4.1481) among mothers in all the three hospitals in 2020 during the COVID period (post lockdown months) of October to December. There was a significant difference in the mode of delivery for mothers (P = 0.0096) with a 95% confidence interval of 1.0664 to 1.5916, as more gave birth through vaginal delivery during the 2020 COVID-19 period than pre-COVID-19. Conclusion: Tertiary-hospital based birth rates were reduced during the pandemic. Our multi-centre study extrapolated on possible factors that may have played a role in this decline in their birth rate, which includes but is not limited to; decreased access to hospital care due to the total lockdowns/curfews and worsening inflation and economic recession in the country.
