Purpose:
Colorectal cancer (CRC) remains a significant global health burden, necessitating innovative approaches for prevention and treatment. This study proposes a multiepitope vaccine targeting carcinoembryonic antigen (CEA) and insulin-like growth factor-1 receptor (IGF-1R), two prominent biomarkers associated with CRC progression.
Methods:
Sequences of CEA and IGF-1R proteins were retrieved from NCBI databank, the sequences were aligned on the MEGA5 tool to identify conserved regions. Immunological and structural predictive analysis which include antigenic potential prediction, cytotoxic T-lymphocytes (CTLs), helper-T lymphocytes (HTLs), B-cell epitopes predictions, and prediction of the vaccine secondary and tertiary structure were performed. The vaccine was evaluated to validate its physiochemical and immunological properties. To determine the binding energy and domain, the tertiary structure of the vaccine was docked to Toll-like receptor 4, and viewed on PyMOL and LigPlot+ tools.
Results:
CEA and IGF-1R were revealed to be highly antigenic, and non-allergens demonstrating the capacity to elicit robust immune responses, which include CTLs, HTLs, and B cells activation. The secondary structure revealed a conformation closely resembling native protein, with alpha helices, beta sheets, and coils, indicative of favorable interactions. Tertiary structure prediction predicted five models, model 0 was selected and validated due its highest confidence, and validation revealed that 87.5% of residues were within favored regions, with a z-score of 4.03. Molecular docking predicted strong binding complex with low binding energy.
Conclusion
Based on our analysis, the proposed multiepitope vaccine holds promise as an effective preventive measure against colorectal cancer development.

Introduction: Pregnancy-related Guillain-Barré syndrome (GBS) is a rare autoimmune disorder that affects pregnant
women. With an annual incidence ranging from 0.81 to 1.89 cases per 100,000 population, GBS can occur at any
trimester of pregnancy, as well as during the postpartum period are susceptible to GBS. The pillars of managing
pregnancy-related GBS to improve outcomes include early diagnosis, prompt immune-modulatory therapy, and multidisciplinary input. Case Series: In this study, three case of GBS in pregnancy were reported. The first patient was a
35-year-old woman, G3A1P2 post emergency Transperitoneal Cesarean Section (TPCS), who experienced with lower limb weakness three days before TPCS. After being diagnosed with severe eclampsia and underwent emergency
TPCS, her complaint of lower limb weakness worsened. The second patient, a 27-year-old woman, with G2P1A0
experienced weakness in all four limbs. The third patient, a 20-year-old woman with G1P0A0, in the third semester
presented with weakness in all four limbs. The electroneurography investigation conducted on these patients supported the diagnosis of GBS, which was subsequently managed with plasma exchange (PE). After the administration
of PE, there was observed improvement in the clinical manifestation of GBS. Conclusion: The development of GBS
in pregnancy is typically preceded by bacterial or viral infection. Preeclampsia was found to be associated with two
folds risk of GBS, which was usually diagnosed based on the neurological examinations with supportive studies, including serological tests, cerebrospinal fluid analysis and electroneurography. The management of pregnancy-related
GBS included intravenous immunoglobulin, PE, physiotherapy, and supportive therapy, such as ventilator support.

Severe hyponatraemia is defined as a sodium level of less than 120 mEq/L, and it is frequently accompanied by
neurological symptoms like coma, convulsions, respiratory arrest, and death. Clinical cardiac toxicity from hyponatremia, such as bradyarrhythmia, is extremely rare. In this article, we present a case of acute severe hyponatraemia
that induced unstable bradyarrhythmia and led to refractory bradycardia, which did not improve despite receiving
treatment in accordance with the standard Advanced Cardiovascular Life Support protocol. The patient’s bradyarrhythmia has completely resolved with the administration of 3% hypertonic saline, which restored her sodium
levels. Due to the possibility that severe hyponatremia may contribute to the aetiology of cardiac malfunction, this
case raises awareness about the significance of closely monitoring electrocardiograms and telemetry in patients with
severe hyponatremia.

Background:
Type 2 diabetes mellitus (T2DM) is a metabolic disorder affecting many organs, including the testis. Naringin from orange peel extract (OPE) is a flavanone with fertility-enhancing properties. Hence, this study was designed to establish the effect of naringin on T2DM-induced testicular dysfunction. Thirty male (30) Wistar rats were randomized into five groups control, diabetes, diabetes + naringin, diabetes + OPE, and diabetes + metformin. The administrations were via the oral route and lasted for 28 days.
Results:
Naringin ameliorated T2DM-induced increase in FBS and decrease in serum insulin. It also abrogated T2DMinduced decrease in sperm quality, gonadotropin-releasing hormone, luteinizing hormone, follicle-stimulating hormone, testosterone, estradiol, prolactin, catalase, superoxide dismutase, and total antioxidant capacity. Furthermore, naringin prevented a T2DM-induced increase in malonaldehyde, tumor necrosis factor-alpha, C-reactive protein, xanthine oxidase (XO), and uric acid (UA), it was accompanied by the restoration of normal testicular histoarchitecture.
Conclusions
Naringin prevented T2DM-induced testicular dysfunction by modulating XO/UA and restoring redox balance. Also, while the animals treated with OPE exhibited better ameliorative effects than their counterparts treated with naringin, the findings from this study showed that naringin would be a promising supplement for treating T2DM-induced male infertility.

Osteoporosis and Sarcopenia 2023;9(2):60-69
Objectives:
The aim of these Clinical Practice Guidelines is to provide evidence-based recommendations to assist healthcare providers in the screening, diagnosis and management of patients with postmenopausal osteoporosis (OP).
Methods:
A list of key clinical questions on the assessment, diagnosis and treatment of OP was formulated. A literature search using the PubMed, Medline, Cochrane Databases of Systematic Reviews, and OVID electronic databases identified all relevant articles on OP based on the key clinical questions, from 2014 onwards, to update from the 2015 edition. The articles were graded using the SIGN50 format. For each statement, studies with the highest level of evidence were used to frame the recommendation.
Results:
This article summarizes the diagnostic and treatment pathways for postmenopausal OP. Risk stratification of patients with OP encompasses clinical risk factors, bone mineral density measurements and FRAX risk estimates. Non-pharmacological measures including adequate calcium and vitamin D, regular exercise and falls prevention are recommended. Pharmacological measures depend on patients’ fracture risk status. Very high-risk individuals are recommended for treatment with an anabolic agent, if available, followed by an anti-resorptive agent. Alternatively, parenteral anti-resorptive agents can be used. High-risk individuals should be treated with anti-resorptive agents. In low-risk individuals, menopausal hormone replacement or selective estrogen receptor modulators can be used, if indicated. Patients should be assessed regularly to monitor treatment response and treatment adjusted, as appropriate.
Conclusions
The pathways for the management of postmenopausal OP in Malaysia have been updated. Incorporation of fracture risk stratification can guide appropriate treatment.

Tibial tuberosity avulsion fracture is a rare injury, and
bilateral occurrence is more uncommon. Periosteal sleeve
fracture is a unique fracture pattern which was first described
in the lower pole of patella in children. We are reporting a
rare case of bilateral tibial tuberosity sleeve fracture in a
teenage boy which occurred while sprinting. The patient
underwent open reduction, pull through suture fixation of the
bilateral tibial tuberosity and screw fixation of left tibial
tuberosity. Post-operative rehabilitation included gradual
increment of range of motion with hinged brace and
quadriceps muscle strengthening. Close follow-up was done
to monitor the progression of his recovery. At six months
follow-up, the patient recovered well. Both knees had full
range of motion with an intact extensor mechanism.

BACKGROUND:
Research is the act of inquiry to know and is one of the pivotal points and fundamental goals of a university. It is an important part of
an academic job and is believed to be the next most valued part of their duty after teaching
OBJECTIVES:
This study aims to determine the research
productivity of Nigerian academics in medicine and allied health sciences disciplines in Nigeria.
METHODOLOGY:
177 participants completed a 41-
items questionnaire that elicits information on sociodemographic, the institution, the program, and research productivity (research papers,
conferences attendance and presentation, and book chapters) using a multistage cluster random sampling of Nigerian Universities.
RESULTS:
Majority of the included participants were male (70.06%), married (79.14%), and below the senior teaching cadre (38.99%). Majority of the
academicians do not have any training overseas (67.06%) and have indicated time as a constraint to research productivity (67.06%). Three papers
in the past two years is an indication that Nigerian academics in the medical and allied health sciences, on average, may not be deemed to be highly
productive. Professors (16.58+27.14) and those in higher ranks (Readers: 11.84+11.22 and senior lectures 12.58+13.53) have published more
papers than their counterparts in the junior cadre (lecturer I and II: 4.87+6.58 and 2.69+3.87). Academics in the present study has a median research
grant of zero in the past two years. A simple majority of the participants (55.29%) agree on mandating of PhD for promotion and career
advancement of academics. There is no difference in the number of papers published (6.04+10.52 and 7.62+13.21) or conferences attended
(7.42+19.14 and 4.04 +4.02) between academics in private and public Universities
CONCLUSION
Apparently low and dismal productivity by these
academics in medicine and allied health sciences affirm the need for capacity building on an ongoing basis.
