Biochemical, morphological and molecular assessments of n butanol fraction of Phoenix dactylifera L. following exposure to inorganic mercury on the liver of Wistar rats.

BACKGROUND: Mercury chloride (HgCl2) damages tissues it comes in contact with in sufficient concentration. This study evaluated the protective effects of n-butanol fraction of Phoenix dactylifera (BFPD) on mercury-triggered liver toxicity in Wistar rats. 25 male rats were divided into 5 groups of 5 rats each. Group I was administered 2 ml/kg of distilled water; group II was administered 5 mg/kg of HgCl2; group III was administered 500 mg/kg of BFPD + 5 mg/kg of HgCl2; group IV was administered 1000 mg/kg of BFPD + 5 mg/kg of HgCl2, while group V was administered 100 mg/kg of silymarin + 5 mg/kg of HgCl2. orally for 2 weeks. The rats were euthanized and liver tissue blood samples were collected for histological, histochemical, stereological, immunohistochemical, molecular, and biochemical studies. RESULTS: The results revealed that HgCl2 induced oxidative stress in the rats evident by histoarchitectural distortions and altered levels of liver enzymes, proteins, and oxidative stress biomarkers when compared to the control. However, BFPD treatment restored these changes. Glutathione peroxidase levels decreased (p < 0.05) in the HgCl2-treated group when compared to the control and BFPD-treated groups. HgCl2 group revealed reduced reactivity with histochemical and immunohistochemical stains (Masson's Trichrome and B cell Lymphoma 2) when compared to the control, with a significant decrease in quantified liver Bcl-2 stain intensity when compared to the silymarin-treated group. BFPD administration revealed normal staining intensity comparable to the control. HgCl2 administration revealed a remarked decrease in the number of hepatocytes when compared to the control, BFPD, and silymarin groups. BFPD preserved (p < 0.05) the stereological features when compared to the HgCl2-treated group. GPx activity in the liver decreased (p < 0.05) with HgCl2 administration when compared to the control and silymarin-treated groups. BFPD attenuated GPx gene activity to levels similar to the control indicating some level of amelioration against HgCl2-induced toxicity. CONCLUSIONS: The ability of BFPD to mitigate HgCl2 triggered liver alterations could be attributed to the antioxidant property of its flavonoid content. Therefore, BFPD may be a potential candidate for treating and managing liver-induced mercury intoxication.

Starch phosphorylation regulates starch granule morphological homogeneity in Arabidopsis thaliana.

Starch granule morphological homogeneity presents a gap in starch research. Transitory starch granules in wild-type plants are discoid, regardless of species. Notably, while the shape of starch granules can differ among mutants, it typically remains homogeneous within a genotype. We found an Arabidopsis thaliana mutant, dpe2sex4, lacking both the cytosolic disproportionating enzyme 2 (DPE2) and glucan phosphatase SEX4, showing an unprecedented bimodal starch granule diameter distribution when grown under a light/dark rhythm. dpe2sex4 contained 2 types of starch granules: large granules and small granules. In contrast to the double starch initiation in wheat (Triticum aestivum) endosperm, where A-type granules are initiated first and B-type granules are initiated later, dpe2sex4 small and large granules developed simultaneously in the same chloroplast. Compared with the large granules, the small granules had more branched amylopectin and less surface starch-phosphate, thus having a more compact structure that may hinder starch synthesis. During plant aging, the small granules barely grew. In in vitro experiments, fewer glucosyl residues were incorporated in small granules. Under continuous light, dpe2sex4 starch granules were morphologically homogeneous. Omitting the dark phase after a 2-wk light/dark cycle by moving plants into continuous light also reduced morphological variance between these 2 types of granules. These data shed light on the impact of starch phosphorylation on starch granule morphology homogeneity.

Acceptance of COVID-19 vaccine and associated factors among healthcare workers in Katsina state: a cross-sectional study in Northwest Nigeria.

OBJECTIVES: Healthcare workers were prioritised to receive the COVID-19 vaccine in Nigeria. Administration of COVID-19 vaccination in Nigeria was challenging because of a lack of trust in vaccine safety and vaccine effectiveness among healthcare workers, who are expected to provide reliable information about vaccines and vaccine-preventable diseases in the communities. Hence, their acceptance and attitudes towards COVID-19 preventive practices could influence the acceptance of the vaccine by the local population. This cross-sectional study assessed the acceptance of the COVID-19 vaccine among healthcare workers in Katsina State. We predicted the variables that increased the vaccine acceptance using logistic regression analysis. SETTING: This hospital-based study was conducted at primary, secondary and tertiary healthcare facilities in Nigeria. PARTICIPANTS: A total of 793 healthcare workers were included in this study. Of these, 65.4% (n=519) were male. OUTCOME MEASURES: To assess acceptance of COVID-19 vaccine measures, and factors increasing acceptance among healthcare workers. RESULTS: Of the healthcare workers, 80% (638) were tested for the SARS-CoV-2, of whom 10.8% (n=65) tested positive. Approximately 97% (n=765) of them believed that the COVID-19 vaccine was safe, and 90% (n=714) received the first dose of the vaccine. Healthcare workers between 30 and 39 years were more likely to accept the vaccine (aOR: 7.06; 95% CI 2.36 to 21.07; p<0.001). Those who had been tested for COVID-19 were more likely (aOR:7.64; 95% CI 3.62 to 16.16; p<0.001) to accept the vaccine. CONCLUSIONS: Our findings showed that the age and prior COVID-19 testing were the main factors influencing the acceptance of the COVID-19 vaccine. There was high acceptance of the COVID-19 vaccine among healthcare workers in Katsina State, Nigeria. Future studies should focus on the completion of doses and serological testing for immunity.

Community engagement; the master key to preventing Nigeria's obvious pandemic fatigue and the next COVID-19 wave.

The index case of COVID-19 in Nigeria was in February 2020. The pandemic has resulted in severe social, economic, and public health challenge in Nigeria. Nigeria has experienced pandemic fatigue (PF) characterized by its low testing capacity, poor public adherence to COVID-19 preventive measures, and the urge to return to normal. This viewpoint examines Nigeria's obvious PF amongst Nigerians and believed that community engagement would be a master key to reducing Nigeria's PF and preventing another wave of the pandemic in Nigeria. Community engagement (CE) is a viable way for monitoring the spread of the SARS-CoV-2. CE is cost-effective, improves the chances of people voluntarily presenting themselves for COVID-19 testing at the grass-root level, and could halt the spread of COVID-19 in Nigeria especially with the detection of the delta and omicron variants in Nigeria.

LIKE EARLY STARVATION 1 alters the glucan structures at the starch granule surface and thereby influences the action of both starch-synthesizing and starch-degrading enzymes.

For starch metabolism to take place correctly, various enzymes and proteins acting on the starch granule surface are crucial. Recently, two non-catalytic starch-binding proteins, pivotal for normal starch turnover in Arabidopsis leaves, namely, EARLY STARVATION 1 (ESV1) and its homolog LIKE EARLY STARVATION 1 (LESV), have been identified. Both share nearly 38% sequence homology. As ESV1 has been found to influence glucan phosphorylation via two starch-related dikinases, α-glucan, water dikinase (GWD) and phosphoglucan, water dikinase (PWD), through modulating the surface glucan structures of the starch granules and thus affecting starch degradation, we assess the impact of its homolog LESV on starch metabolism. Thus, the 65-kDa recombinant protein LESV and the 50-kDa ESV1 were analyzed regarding their influence on the action of GWD and PWD on the surface of the starch granules. We included starches from various sources and additionally assessed the effect of these non-enzymatic proteins on other starch-related enzymes, such as starch synthases (SSI and SSIII), starch phosphorylases (PHS1), isoamylase and ß-amylase. The data obtained indicate that starch phosphorylation, hydrolyses and synthesis were affected by LESV and ESV1. Furthermore, incubation with LESV and ESV1 together exerted an additive effect on starch phosphorylation. In addition, a stable alteration of the glucan structures at the starch granule surface following treatment with LESV and ESV1 was observed. Here, we discuss all the observed changes that point to modifications in the glucan structures at the surface of the native starch granules and present a model to explain the existing processes.

Assessment of COVID-19 Information Overload Among the General Public.

BACKGROUND: A relentless flood of information accompanied the novel coronavirus 2019 (COVID-19) pandemic. False news, conspiracy theories, and magical cures were shared with the general public at an alarming rate, which may lead to increased anxiety and stress levels and associated debilitating consequences. OBJECTIVES: To measure the level of COVID-19 information overload (COVIO) and assess the association between COVIO and sociodemographic characteristics among the general public. METHODS: A cross-sectional online survey was conducted between April and May 2020 using a modified Cancer Information Overload scale. The survey was developed and posted on four social media platforms. The data were only collected from those who consented to participate. COVIO score was classified into high vs. low using the asymmetrical distribution as a guide and conducted a binary logistic regression to examine the factors associated with COVIO. RESULTS: A total number of 584 respondents participated in this study. The mean COVIO score of the respondents was 19.4 (± 4.0). Sources and frequency of receiving COVID-19 information were found to be significant predictors of COVIO. Participants who received information via the broadcast media were more likely to have high COVIO than those who received information via the social media (adjusted odds ratio ([aOR],14.599; 95% confidence interval [CI], 1.608-132.559; p = 0.017). Also, participants who received COVID-19 information every minute (aOR, 3.892; 95% CI, 1.124-13.480; p = 0.032) were more likely to have high COVIO than those who received information every week. CONCLUSION: The source of information and the frequency of receiving COVID-19 information were significantly associated with COVIO. The COVID-19 information is often conflicting, leading to confusion and overload of information in the general population. This can have unfavorable effects on the measures taken to control the transmission and management of COVID-19 infection.

Effects of dietary Mitracarpus scaber leaves extract on growth, physiological, antioxidants, and mucosal immune profiles of North African catfish, Clarias gariepinus, and resistance against Edwardsiella tarda infection.

This study evaluated the effect of Mitracarpus scaber leaves extract (MSLE) as a dietary supplement on growth performance, physiological, antioxidants, and mucosal immune profiles of North African catfish, Clarias gariepinus, and resistance to Edwardsiella tarda infection. Four isonitrogenous diets containing 0, 2, 4, or 6 MSLE g/kg were fed to North African catfish fingerlings (n = 240; mean weight = 5.80 g) for 56 days. After the feeding trial, 10 fish from each experimental tank were intraperitoneally injected with E. tarda (ATCC 15,947; 1.0 × 108 CFU/mL) while clinical signs and mortalities were observed for 14 days. The results show that North African catfish fed dietary MSLE had better growth performance, physiological antioxidants, and mucosal immune profiles than when fed a control diet. The best growth, physiological, antioxidant, and mucosal immune response profiles were noticed in the fish fed diet containing 6 MSLE g/kg. Furthermore, fish fed 6 MSLE g/kg diet had a higher survival rate after E. tarda infection. These results indicated that supplementation of MSLE at 6 g/kg improves growth, physiological, antioxidant, and mucosal immune profiles, and promotes resistance of North African catfish.

Antibacterial effect of acidic ionized water on horse wounds bacterial isolates.

BACKGROUND AND AIM: Horse wounds can be easily infected with bacteria depending on the nature of its cause such as laceration, abrasion, or puncture as well as the nature of its environment. Various treatments are available in managing open wounds, including the usage of topical antibiotics and antiseptics. However, antibiotic resistance has been a major concern attributed with chronic wound infection. The aim of this study was to test the efficacy of ionized water at different pH against the growth of common bacteria from horse wounds. MATERIALS AND METHODS: Ten swab samples from equine infected wounds were collected and bacteria isolation and identification were performed. The antibacterial effect of the ionized water of pH 2.5, 4.5, 7.0, and 11.5 was tested on Staphylococcus aureus, Staphylococcus pseudintermedius, Staphylococcus intermedius, Escherichia coli, Pantoea agglomerans, and Klebsiella pneumoniae. The time-kill profiles of the ionized waters were determined at time 0, 2, 4, 6, and 8 h. RESULTS: Ionized water of pH 2.5 and 4.5 showed antibacterial activity against S. aureus, S. pseudintermedius, and S. intermedius with significant (p>0.05) reduction in colony-forming unit/mL within 2-8 h. The degree of bactericidal effect of the acidic ionized water differs between the species with S. intermedius more susceptible. However, there was no antibacterial effect at pH 2.5, 4.5, 7.0, and 11.5 on the Gram-negative bacteria tested. CONCLUSION: Ionized water of pH 2.5 and 4.5 is effective in minimizing the growth of Gram-positive bacteria; thus it could be of clinical importance as an antiseptic for surface wound lavage in horses.

Biomechanical Effects of Unidirectional Expansion Using Anisotropic Expanders in Horse Skin Tissue.

The use of a self-inflating tissue expander is a technique to stretch cutaneous tissues for potential use in reconstructive skin surgeries. This study investigates the mechanical properties of horse skin stretched by the subcutaneous implantation of anisotropic tissue expanders at the forehead, right shoulder, and dorsomedial part of the cannon region of the right forelimb in six (n = 6) horses. After 14 days of skin expansion, expanded and normal (control) skin samples were harvested and their mechanical properties of elastic modulus (EM), maximum force (MF), maximum stress (MSs) and maximum strain (MSr) were evaluated using uniaxial tension test. The expanded skin from shoulder area has higher EM, MSs, MSr and MF than the normal skin when compared to the forehead and lower forelimb. Statistically, there was a significant (P= .02) mean difference for MSs between the expanded shoulder and lower forelimb skin, but the pairwise comparison of EM, MSr and MF showed no significant difference between the locations. The overall effect of locations on EM and MSs was statistically significant (P < .05), however, there was no overall effect of horse factor, treatment factor (normal and expanded skin) and location interaction on the EM, MSS, MF and MSr. In conclusion, the expanded skin from the frontal head and the distal limb are less elastic (stiffer) compared to that of the expanded skin of the shoulder, thus anatomical location of the skin has some degree of effect on EM and MSs.

Socio-Demographic Characteristics of COVID-19 Vaccine Recipients in Kwara State, North Central Nigeria.

Understanding key socio-demographic variables of 2019 coronavirus disease (COVID-19) vaccine recipients is crucial to improving its acceptance and Nigeria's COVID-19 control strategy. The survey was conducted as a non-probability cross-sectional survey of 2,936 COVID-19 vaccine recipients in Kwara State. Our findings revealed that 74% (n = 2,161) of the vaccine recipients were older than 40 years. Forty percent (n = 1,180) of the vaccine recipients earned a monthly income >100,000 Naira (equivalent to US $200). Most of the vaccine recipients (64%, n = 1,880) had tertiary education, while 15% (n = 440) of them had no formal education. Almost half of the recipients (47%, n = 1,262) were government employees and 28.8% (n = 846) of them had health-related backgrounds. Only 17% (n = 499) of the vaccine recipients have been screened for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), of which 21% (n = 105/499) of them were tested positive. Only 47% (n = 1,378) had been fully immunized. The prevalence of confirmed COVID-19 cases among COVID-19 vaccine recipients in Kwara State was 3.6% (n = 105/2,936). The most recurrent adverse events following immunization (AEFIs) among vaccine recipients were fever (14%, n = 411), pain at injection site (47%, n = 1,409), headache (19%, n = 558), and body weakness (9%, n = 264). The need to protect themselves from the deadly virus was the main reason that prompted people to voluntarily accept the COVID-19 vaccine. There is a high level of COVID-19 vaccine acceptance among respondents across all social classes including those with no formal education, those with very low monthly income (< US $2 per day), and in untested population. Hence, vaccine donors should prioritize equitable distribution to Low-and-Middle-income Countries (LMICs) such as Nigeria, and health authorities should improve vaccine advocacy to focus on vaccine safety and efficacy.

Clinical assessment and grading of back pain in horses.

BACKGROUND: The clinical presentation of horses with back pain (BP) vary considerably with most horse's willingness to take part in athletic or riding purpose becoming impossible. However, there are some clinical features that are directly responsible for the loss or failure of performance. OBJECTIVES: To investigate the clinical features of the thoracolumbar region associated with BP in horses and to use some of the clinical features to classify equine BP. METHODS: Twenty-four horses comprised of 14 with BP and 10 apparently healthy horses were assessed for clinical abnormality that best differentiate BP from normal horses. The horses were then graded (0-5) using the degree of pain response, muscular hypertonicity, thoracolumbar joint stiffness and overall physical dysfunction of the horse. RESULTS: The common clinical features that significantly differentiate horses with BP from non-BP were longissimus dorsi spasm at palpation (78.6%), paravertebral muscle stiffness (64.3%), resist lateral bending (64.3%), and poor hindlimb impulsion (85.7%). There were significantly (p < 0.05) higher scores for pain response to palpation, muscular hypertonicity, thoracolumbar joint stiffness and physical dysfunction among horses with BP in relation to non-BP. A significant relationship exists between all the graded abnormalities. Based on the cumulative score, horses with BP were categorized into mild, mild-moderate, moderate and severe cases. CONCLUSIONS: BP in horse can be differentiated by severity of pain response to back palpation, back muscle hypertonicity, thoracolumbar joint stiffness, physical dysfunctions and their cumulative grading score is useful in the assessment and categorization of BP in horses.

Myelopathy and Reactive Microgliosis and Astrogliosis in Equine Back Pain.

Equine chronic back pain (CBP) has been linked to different pathologic processes, which directly or indirectly involve spinal structures. Thus, making diagnosis and management very challenging with most horses with the condition recommended for early retirement from athletic activity. This study described the spinal cord lesions and the development of reactive microgliosis and astrocytosis in the spinal cords of horse with CBP. Thoracolumbar spinal cord segments from three horses euthanized because of unresolved CBP were dissected and grossly and histopathologically examined. The expression of activated microglia and astrocytes were demonstrated immunohistochemically using polyclonal rabbit anti-Iba-1 and anti-glial fibrillary acidic protein antibodies, respectively. All horses had radiological evidence of varying degrees of kissing spine involving six to nine vertebrae with the majority of the lesions graded between 2 and 5. Grossly, there was myelomalacia with intramedullary hemorrhages. The gray matters of the spinal cords were characterized by hemorrhagic malacic lesions with medullary disintegration. Reactive microgliosis and astrocytosis were evident in the spinal dorsal horns. White matter lesions include axonal swollen and/or loss, satellitosis, and varying degrees of dilation of myelin sheaths with some containing macrophages. In conclusion, the presence of reactive microgliosis and astrogliosis in the spinal dorsal horn indicates that they are possible precipitating factors in the development of equine CBP.

Dietary supplementation with Lactobacillus acidophilus enhanced the growth, gut morphometry, antioxidant capacity, and the immune response in juveniles of the common carp, Cyprinus carpio.

This study investigated the effect of Lactobacillus acidophilus-fortified diets on growth performance, antioxidant profiles, and immunity-related gene expressions of common carp, Cyprinus carpio juveniles. Four isonitrogenous diets containing 0, 102, 104, or 106 cfu/mL/kg L. acidophilus were fed to 240 Cyprinus carpio juveniles (mean = 21.34 ± 1.85 g), allotted to 12 rectangular tanks in a completely randomized designed at 3% body weight for 56 days. Growth performance and nutrient utilization were evaluated using standard procedures. Intestinal villi were measured, antioxidant profiles were evaluated from blood sera, and immunity-related gene expressions were evaluated. The results revealed that fish fed dietary 106 had significantly higher weight gain, SGR, feed intake, and lower FCR. Also, villi length, width, and areas of absorption were significantly improved in a dose-dependent manner. Furthermore, innate immune profiles, superoxide dismutase, catalase, respiratory bust activity as well as transforming growth factor beta (TGFß), interleukin 8 (IL-8), and tumor necrosis factor alpha (TNF-alpha) were significantly stimulated. This study evoked that Lactobacillus acidophilus supplementation enhanced better growth performance, improved antioxidant profiles, and modulated expression of immune-related genes of common carp, Cyprinus carpio, than the fish fed control diet. Results show that fish fed fortified diets had better growth performance, improved antioxidant profiles, and modulated expression of immune-related genes.

Biofluid Markers of Equine Neurological Disorders Reviewed From Human Perspectives.

Neurological disorders (NDs) are often fatal to horses. Thus, symptoms of equine NDs commonly indicate euthanasia. Current diagnostic approaches for equine NDs is based on clinical signs, differential diagnoses, analysis of cerebrospinal fluid (CSF), assessment of histopathological lesions, and imaging. However, advances in biofluid biomarkers in the diagnosis of human neurological diseases can potentially be applied to equine NDs. In this review, we described the established human blood and CSF neurobiomarkers that could potentially be used to diagnose equine NDs.

Comparative diagnosis of pregnancy wastage in cows at slaughter using pregnancy specific protein-B and post slaughter inspection diagnostic procedures.

Slaughter of pregnant animals is a common abattoir practice. This study was designed to compare the diagnostic capacity of pregnancy specific protein-B (PSPB) with post slaughter inspection (PSI) procedures in detecting cows pregnant at slaughter. Blood was collected from cows presenteded for slaughter at an abattoir. The uteri were examined post slaughter for the presence or absence of a foetus. Recovered foetuses were aged using crown-rump length to estimate the stage of pregnancy. Of the 361 cows examined, 72 (19.9 %) were diagnosed pregnant using the PSPB procedure, while 32 (8.9 %) were diagnosed pregnant using PSI diagnosis. Furthermore, with PSI there was a lack of pregnancy diagnosis in 42 (11.6 %) cows detected pregnant using PSPB procedure, and two (0.6 %) cows detected pregnant using PSI were not detected to be pregnant using PSPB diagnosis. Validity of the diagnostic procedures indicated that sensitivity and specificity of the PSPB was 93.8 % and 87.2 %, respectively, while with the PSI diagnosis there was a sensitivity and specificity of 41.7 % and 99.3 %, respectively. The PSPB diagnosis, had an excellent predictive value (AUC - 0.92; p < 0.001; 95 % CI - 0.856 to 0.981). Most of the pregnancy wastage (n = 22; 68.8 %) diagnosed using the PSI method were in the second trimester. The results of this study indicate that PSPB is reliable and a more sensitive diagnostic method than PSI . It is therefore recommended that the PSPB test be incorporated in routine screening for pregnancy status of cows before slaughter.

Clinical investigation of back disorders in horses: A retrospective study (2002-2017).

BACKGROUND AND AIM: Back disorder is an ailment that often affects athletic and riding horses. Despite the rapidly growing equine athletic and equestrian activities, there is no documentation on the nature of equine back disorder (EBD) in Malaysian horses. The purpose of this study was to characterize EBD cases presented to University Veterinary Hospital, Universiti Putra Malaysia, between 2002 and 2017. MATERIALS AND METHODS: The compilation of data was based on signalment, case history, duration of clinical signs, anatomical location of the pain, method of diagnosis, type of EBD, treatment, and outcome. The diagnosis of EBD was based on a history of poor performance, clinical examination findings, radiography, and, where applicable, necropsy. RESULTS: A total of 181 diagnosed cases of EBDs were identified. The age of horses ranged from 5 to 22 years. The EBD cases were more prevalent in male than female horses and predominantly in geldings (60.77%). Thoroughbred, Arab, Polo pony, and Warmblood also recorded the most EBD cases among breeds. The discipline of horses tended to influence the development of EBDs, with patrolling horses recording the highest frequency. Most EBD cases were of the primary type (92.27%), with the main causes being soft-tissue lesions (57.48%), vertebral lesions (18.56%), tack-associated problems (16.77%), and neurological lesions (7.19%). The common treatments employed were administration of nonsteroidal anti-inflammatory agents, 1 to 3-month rest, warm and cold compression therapy, massage therapy, exercise adjustment, as well as correction of ill-saddle fit. CONCLUSION: Most EBDs in this study were associated with soft-tissue lesions. Among vertebral lesions, kissing spines were the most common cause of EBDs in horses in Malaysia.

Mammographic screening patterns in Sokoto, Northwestern Nigeria

Background: Screening mammography is a radiographic examination of the breast performed for early detection of breast cancer in asymptomatic women. The American College of Radiology recommends that women should have mammography at the age of 40 years and annually thereafter. However, those who are at increased risk of breast cancer should start screening mammography earlier. These include patients with a strong family history of breast cancer or those who had radiotherapy to the chest wall.Objective: This study is aimed at evaluating the mammographic outcomes among 77 Nigerian females who had screening mammographic breast examination. Materials and Methods: From December 2010 and November 2012, 77 females had routine screening mammography in the department with the general electric alpha­RT machine with model number MGF­101 (manufactured 2010). All the participants had to fill a mammographic form consisting of variables such as age, sex, occupation, family history ofbreast cancer, tribe, contraception, parity and caffeine consumption, history of surgical intervention (lumpectomy, biopsy, and/or mastectomy), previous mammography, and last childbirth. Mediolateral­oblique and cranial­caudal views were done for the breast examination though additional were occasionally employed. Results: Seventy­seven females had screening mammography. The minimum age recruited was 40 years. The mammographic outcome for those who had screening was normal in 51 (66.2%) and abnormal in 26 (33.8%) participants. The abnormal mammographic outcomes were architectural distortion in either or both breasts in 13 (16.9%) participants, masses in either or both breast in 11 (14.3%) participants, while isolated calcification in either or both breast among 2 (2.6%) participants. Two (18.2%) of the subjects with masses had associated macrocalcification. No masses with malignant features were seen. Conclusion: Screening mammography was found out to be useful in detecting various forms of breast pathologies which were mostly breast masses, calcifications, and architectural distortions. Screening mammography is, therefore,advised yearly and routinely for women age 40 years and above

Prevalence and outcome of hypoglycemia in children attending emergency pediatric unit of a specialist hospital in Nigeria

Background: Hypoglycemia is a common metabolic problem encountered in pediatric emergency admissions. The absence of clinical symptoms does not preclude the presence of hypoglycemia as presentation may vary from asymptomatic to central nervous system and cardiopulmonary disturbances. If untreated, hypoglycemia can result in permanent neurological damage or even death. Objectives: The objective of the study is to determine the prevalence, associated factors and outcome of hypoglycemia in pediatric emergency admissions at Ahmad Sani Yariman Bakura Specialist Hospital, Gusau, Nigeria. Materials and Methods: The study was a prospective cross­sectional study involving children aged 1 month­13 years. Blood glucose was determined at admission using Accu­Chek® Active Blood Glucose Meter, and hypoglycemia was defined as blood glucose levels <2.8 mmol/L (<50 mg/dL). Age of the patients, sex, interval of last meal, presenting complaints diagnoses were recorded. Results: A total of 154 children were studied.Thirty (19.5%) were infants and 71 (46.1%) were under­fives. Eighty­seven (56.5%) were males with male to female ratio of 1.3:1.The prevalence of hypoglycemia was 22.1%. The predominant disease conditions the children with hypoglycemia presented with were severe malaria, acute diarrheal disease, and sepsis. The prevalence of hypoglycemia was significantly higher among children whose last meal was 8 h and above before presentation (42.9%). Children who presented with hypoglycemia were significantly more likely to die (odds ratio [OR] =13.3; 95% confidence interval [CI] =4.6­38.7). Among those with hypoglycemia, males were significantly more likely to die (OR = 4.2, 95% CI = 1.0­18.0). Hypoglycemia was significantly associated with mortality in children with severe malaria and pneumonia (P = 0.04 and 0.01, respectively). Conclusion: The prevalence of hypoglycemia is still high in our emergency admissions. It is associated with significant mortality especially among male children and those presenting with severe malaria and pneumonia. We recommend that hypoglycemia sought for and promptly treated in children presenting to emergency to reduce mortality
