Background: multiple sclerosis (MS) presentation varies depending on the location and severity of the lesions affecting different areas of the spinal cord and brain. Extensive research has focused on specific systems to detect the disease in its various stages. The objective of this study was to investigate the concentration of the soluble scavenger receptor for haptoglobin–haemoglobin complex (Hb-Hp), sCD163, which is mostly expressed by monocytes and protects tissues from oxidative damage, in patients with MS. Methods: enzyme-Linked Immunosorbent Assay (ELISA) analysis was conducted in plasma samples collected from twenty-three relapsing–remitting MS (RRMS) subjects treated with teriflunomide and ten healthy control subjects (HCs). Results: the study results showed no differences between RRMS subjects and HCs in the concentration of CD163. A significantly higher concentration of sCD163 in RRMS was found in men in comparison to women (p = 0.038, Cohen d = 0.97). Conclusions: a significant correlation between disease activity, estimated using plasma-soluble CD163 (sCD163) and clinical assessment of the Expanded Disability Status Scale (EDSS) (p = 0.021), was detected in female patients with RRMS.

Background/Objectives—The personalisation agenda—matching the correct psychological therapy to diverse and comorbid mental disorders—is an unanswered dilemma in the worldwide literature which has far reaching consequences for public health. This hypothesis article addresses the question: can a biomedical approach resolve the personalisation agenda? Methods—Narrative review drawing on clinical psychology, translational psychiatry, and biomedical science literature. Results—Diverse attempts to resolve the personalisation agenda have not yet succeeded. Randomised controlled trials are uniquely biased due to unwanted placebo effects; network meta-analysis cannot address adequately which psychological therapy to use; new methodologies have not yet produced data; and neuroscientific analysis cannot yet explain how trauma-based therapies work. However, a biomedical model which divides psychological therapy into low, medium and high intensity interventions can resolve the personalisation agenda. Conclusions—Combining low intensity (placebo), with medium intensity (cognitive behavioural techniques) and high intensity interventions (trauma-based therapies) are theoretically synergistic if combined with psychosocial treatments/exercise, and used in sequence in the correct order. A biomedical model based on recent advances in placebo studies and neuroplasticity can resolve the personalisation agenda, and improve outcomes for mental disorder. Full article

Background: The incidence of chemical ocular trauma after accidentally instilling the “wrong” eyedrops is still frequent, but cases resulting from stamper ink refills are rare. Case Presentation: A 73-year-old man presented to our emergency department with a history of inadvertently instilling stamper ink refill into both eyes (BEs) instead of artificial tears. Immediate irrigation and evaluation were performed. The initial visual acuity (VA) was 0.4 in the right eye (RE) and 0.8 in the left eye (LE). Slit lamp examination showed edema palpebra with periocular blue staining in BEs, chemotic conjunctiva with a much darker color in the RE than the LE, and epithelial defects with a positive fluorescein test in BEs. A diagnosis of bilateral corneal abrasion and chemotic conjunctiva was established. Ten hours after the emergency visit, RE VA decreased to 0.2, and corneal edema was found during the follow-up examination. Medications including levofloxacin antibiotic, sodium hyaluronate, sodium chloride, combined polymyxin sulfate–neomycin sulfate and dexamethasone eyedrops, mefenamic acid, and ascorbic acid tablets were prescribed. The RE corneal edema still occurred, and the endothelial cell count was 1952 and 987 cells/mm² in the RE and LE at the one-week follow-up. After three weeks, corneal edema had fully resolved, and the VA was 0.4 and 0.8 in the RE and LE, respectively. Conclusions: This case report adds to the spectrum of the continuing problem of chemical ocular trauma after mistakenly instilling the eyedrops. Promoting and changing to different packages for non-ophthalmic products in plastic bottles mimicking eyedroppers is essential to minimize these injuries. Full article

Diverticulosis is characterized by sac-like bulges of the mucosa through weakened portions of the intestinal wall, and is a common pathology observed in adult patient populations. The majority of diverticular disease and associated complications, such as inflammation of diverticula, form within the colon, with less frequent cases of diverticular disease observed in the small bowel. We present the case of a 48-year-old female who presented to the emergency department with a two-day history of abdominal pain, fever, and nausea. Upon admission, vital signs indicated fever and laboratory analysis demonstrated elevated white blood cell count. The patient’s workup included a computed tomography (CT) scan of the abdomen which revealed diffuse small bowel diverticulitis with surrounding inflammation, lymph node enlargement, and bowel wall thickening. CT scan of the abdomen with evidence of diverticula in the bowel wall is diagnostic of diverticulosis. Treatment could include bowel rest, clear liquid diet, broad-spectrum antibiotics, or surgical intervention. This case emphasizes the importance of CT imaging and consideration of broad differential diagnosis in patients presenting with abdominal pain due to the rare presentation of small bowel diverticulitis and aims to contribute to the current understanding and treatment of clinically significant diverticular pathologies.

Objective: The primary objective was to identify whether there were differences in performance for the individual subcomponents of the instrumented timed “Up and Go” (iTUG) between adults with traumatic brain injury (TBI) and healthy controls. Methods: Fifteen adults with moderate-to-severe TBI and fifteen age- and sex-matched controls completed two separate trials of the iTUG. Paired t-tests or Wilcoxon signed rank tests were used to determine the differences between groups. Results: Adults with moderate-to-severe TBI took more time to complete the iTUG (14.50 ± 2.36 s vs. 9.85 ± 1.71 s; p-value = 0.0002), had slower chest flexion angular velocities (63.52 ± 23.25 s vs. 88.19 ± 29.20 s; p-value = 0.0486) and vertical acceleration (2.22 [1.23–2.74] s vs. 3.89 [3.36–5.02] s; p-value = 0.0005) during the sit-to-stand movements, and had slower angular velocities during the turns (p-value < 0.05 for both mean and peak turn angular velocities) compared with the controls. Conclusions: Adults with moderate-to-severe TBI completed the iTUG more slowly than healthy controls. Significant differences were noted in the sit-to-stand and turn subcomponents for adults with moderate-to-severe TBI compared with healthy controls, which would not be apparent from evaluating the total time taken alone.

Background/Objectives: Cardiovascular diseases are a global health issue with an increasing burden and are exacerbated by hypertension. High blood pressure is partly attributed to genetic variants that are generally not well understood or extensively studied in sub-Saharan African populations. Variants linked to blood pressure have been found through genome-wide association studies (GWASs), which were mostly conducted among European ancestry populations; however, limited research has been undertaken in Africa. The current study evaluated single-nucleotide polymorphisms (SNPs) of PCSK9, ABCA1, LPL, and PON1 in relation to blood pressure measurements of 1839 Ghanaian adults. Methods: Genotypes were extracted from data generated by the H3Africa SNP array. After adjusting for sex, age, smoking, and body mass index (BMI), inferential statistics were used to investigate the relationships between SNPs and blood pressure (BP) indices. Additionally, Bonferroni correction was used to adjust for multiple testing. Results: Diastolic blood pressure (DBP) and the minor allele T of the PCSK9 variant (rs17111557) were positively associated at p = 0.006 after covariate adjustments. Although this novel DBP-associated variant is located in the 3′ untranslated region (3′ UTR) of the PCSK9 gene, in silico functional prediction suggests it is an expression quantitative trait locus (eQTL) that may change the binding site of transcription factors, potentially altering the rate of transcription and impacting DBP in this Ghanaian population. Conclusions: Our findings highlight the role of genetics in hypertension risk and the potential of discovering new therapies targeting isolated diastolic blood pressure in this rural African population.
