Prognostic variables predict clinical outcome after decompressive craniectomy: A single institute experience; A retrospective study

Decompressive craniectomy (DC) is a well-established neurosurgical intervention in patients with high intracranial pressure who fail to respond to medical treatment. Data on predictive factors for functional outcomes in patients with DC who have malignant middle cerebral artery (MCA) infarction as opposed to intracranial hemorrhage (ICH) are scarce. Eighty-four patients who underwent DC treatment for ICH and malignant MCA infarction were examined. All patients underwent surgery in the Bahrain Salmaniya Medical Complex Neurosurgery Unit between January 2017 and June 2021. To determine whether any of these demonstrated a link to the functional outcome, radiographic factors were compared with clinical data. The postsurgical midline shift (MLS) (ICH group) showed the strongest correlation (ρ = 0.434; P = .006), as in the MCA infarction group as well (ρ = 0.46; P = .005). Further analyses using binary logistic regression with postsurgical basal cistern status and ∆ MLS, and it was observed to be statistically significant (odds ratios: 0.067, 95% CI: 0.007, 0.67; P = .021). The initial Glasgow coma scale, postsurgical MLS, basal cistern status, and ∆ are Measurable variables that can be used to predict outcomes in the groups with ICH and MCA infarction.

Determinants of early sexual initiation among female adolescents in Bangladesh: evidence from a countrywide cross-sectional survey

OBJECTIVES

Early sexual initiation (ESI), defined as sexual activity that begins before 15 or 18 years of age, is one of the risky sexual behaviours that has been linked to increased likelihood of adverse consequences, such as sexually transmitted diseases, unintended pregnancies and unsafe abortions. However, to date, there are no studies investigating the prevalence and factors influencing ESI among adolescent females (aged 10-19 years) in Bangladesh. Thus, this study aimed to identify the potential determinants of ESI among adolescent females in Bangladesh based on data that are representative of the country.

STUDY DESIGN

This was a cross-sectional study.

METHODS

Based on the availability of the data, the analysis included a weighted sample of 2051 adolescent females aged 15-19 years from the Bangladesh Demographic and Health Survey 2017/18. Initial selection of predictor variables was based on the bivariate analysis using the Chi-squared test. Univariate and multivariable logistic regression modelling were performed to measure the crude and adjusted effect of the selected predictor variables on ESI using the odds ratio (OR). The elasticity of the effects was calculated by their 95% confidence intervals (CIs).

RESULTS

Approximately 22% and 85% of female adolescents experienced ESI before the age of 15 and 18 years, respectively. Findings revealed that illiteracy (adjusted OR [AOR]: 3.61, 95% CI: 1.82-7.18), primary education (AOR: 2.08, 95% CI: 1.60-2.69), working status (AOR: 1.25, 95% CI: 0.98-1.60), living in Chittagong (AOR: 0.46, 95% CI: 0.27-0.79), living in Sylhet (AOR: 0.21, 95% CI: 0.08-0.56), reading newspapers (AOR: 0.63, 95% CI: 0.40-1.01), earlier marriage preference (AOR: 3.30, 95% CI: 2.31-4.71) and later marriage preference (AOR: 4.10, 95% CI: 3.01-5.59) were significantly linked with ESI before the age of 15 years. ESI before the age of 18 years was significantly association with primary education (AOR: 1.47, 95% CI: 1.01-2.13), religion (AOR: 0.55, 95% CI: 0.32-0.94), female household head (AOR: 1.93, 95% CI: 1.17-3.19), living in Rajshahi (AOR: 1.97, 95% CI: 0.95-4.08), being in the 'poorest' wealth category (AOR: 2.43, 95% CI: 1.45-4.07), being in the 'poorer' wealth category (AOR: 1.70, 95% CI: 1.06-2.72), being in the 'middle' wealth category (AOR: 1.76, 95% CI: 1.12-2.77), being in the 'richer' wealth category (AOR: 1.58, 95% CI: 1.02-2.44), earlier marriage preference (AOR: 15.71, 95% CI: 9.09-27.14), later marriage preference (AOR: 12.62, 95% CI: 8.82-18.06) and heard about family planning (AOR: 0.70, 95% CI: 0.47-1.04).

CONCLUSIONS

In Bangladesh, the prevalence of ESI among female adolescents is a public health concern. Due to the detrimental impact of ESI on the well-being of adolescents, it is crucial that policymakers consider the factors influencing ESI that have been identified in this study when designing health strategies. The findings from this study will help the development of evidence-based effective initiatives by policymakers in collaboration with governmental and non-governmental organisations.

Effects of combined treatment of probiotics and metformin in management of Type 2 diabetes: A systematic review and meta-analysis

BACKGROUND

Lifestyle changes and dietary intervention, including the use of probiotics, can modulate dysbiosis of gut microbiome and contribute to the management of type 2 diabetes mellitus (T2DM). This systematic review and meta-analysis aim to assess the efficacy of metformin plus probiotics versus metformin alone on outcomes in patients with T2DM.

METHODS

We searched MEDLINE and EMBASE from inception to February 2023 to identify all randomized controlled trials (RCTs), which compared the use of metformin plus probiotics versus metformin alone in adult patients with T2DM. Data were summarized as mean differences (MD) with 95% confidence interval (CI) and pooled under the random effects model. Findings Fourteen RCTs (17 comparisons, 1009 patients) were included in this systematic review. Pooled results show a significant decrease in fasting glucose (FG) (MD=-0.64, 95% CI=-1.06, -0.22) and HbA1c (MD=-0.29, 95% CI=-0.47, -0.10) levels in patients with T2DM treated with metformin plus probiotics versus metformin alone. The addition of probiotics to metformin resulted in lower odds of gastrointestinal adverse events (Odds ratio=0.18, 95% CI=0.09, 0.3.8; I²=0%).

CONCLUSIONS

The addition of probiotics to metformin therapy is associated with improvement in T2DM outcomes. However, high-quality and adequately reported RCTs are needed in the future to confirm our findings.

Gaps in pharmaceutical care for patients with mental health issues: A cross-sectional study

Background

Mental health issues such as depression and anxiety are often underdiagnosed and undertreated. Medications are a primary method of managing mental health problems, and pharmacists therefore have a vital role in supporting patients and providing them with information about the safety and efficacy of mental health medications. However, the potential role of pharmacists in managing mental health issues in Jordan has not been well established.

Aim

This study aimed to assess Jordanian pharmacists’ attitudes and actual practices related to the provision of mental health services.

Method

This was an exploratory cross-sectional study that used a self-report questionnaire among a convenience sample of 347 pharmacists in Amman, the capital of Jordan.

Results

The participating pharmacists had positive attitudes towards providing care for patients with mental health problems. However, their actual practices did not resonate with their enthusiasm, particularly in terms of the long-term follow-up of disease symptoms and medication side effects and adherence. The participating pharmacists showed an eagerness to collaborate with their colleagues, but their level of actual cooperation was lower than desired. The most reported barrier to providing care for patients with mental health problems was the lack of education on mental health issues (71.5%), followed by the lack of privacy in pharmacy settings (53.9%).

Conclusion

To be effectively involved in the provision of care to mental health patients, pharmacists should receive adequate education/training related to mental health issues, and pharmacies should be redesigned to provide private areas for patient counseling.

Mogamulizumab efficacy is underscored by its associated rash that mimics cutaneous T-cell lymphoma: a retrospective single-centre case series

BACKGROUND

Mogamulizumab is a humanized antibody against chemokine receptor type 4. It was recently approved by the US Food and Drug Administration for relapsed or refractory mycosis fungoides (MF) and Sézary syndrome (SS). The most commonly reported adverse event in the phase III licensing trial was drug eruption (28%), now termed mogamulizumab-associated rash (MAR). Clinical recommendations about MAR and its treatment differ between the current package insert and postapproval insights reported from two single-centre studies that focused on its characterization, but less so on outcomes and clinicopathological differentiation from cutaneous T-cell lymphoma (CTCL).

OBJECTIVES

To describe our experience in the diagnosis of MAR and treatment of patients with CTCL with mogamulizumab.

METHODS

This is a single-centre retrospective case series study.

RESULTS

We found a higher incidence of MAR in patients with CTCL (17 of 24, 68%) than previously reported. MAR development is associated with complete (11 of 17) or partial (four of 17) responses, with an overall response rate of 88%, compared with 29% (two of seven) in patients without MAR. Diagnosis of MAR may be obscured by its ability to mimic key CTCL features both clinically and histologically, but an absence of T-cell-receptor clonality and relatively decreased CD4 : CD8 ratio compared with baseline lesions strongly favour MAR over recurrent disease.

CONCLUSIONS

MAR has the potential to create a significant management problem for patients on mogamulizumab. Misidentification of MAR as recurrent CTCL may detrimentally result in the premature discontinuation of mogamulizumab in patients whose disease is historically hard to treat. Thorough clinicopathological investigation of new lesions during treatment with mogamulizumab is required to inform ideal treatment decisions and achieve better outcomes.

Neuromyelitis optica spectrum disorders in Arabian Gulf (NMOAG); establishment and initial characterization of a patient registry

OBJECTIVE

To describe the clinical and radiological characteristics of neuromyelitis optica spectrum disorders (NMOSD) patients from the Arabian Gulf relative to anti-aquaporin 4 antibody serostatus.

METHODS

Retrospective multicentre study of hospital records of patients diagnosed with NMOSD based on 2015 International Panel on NMOSD Diagnosis (IPND) consensus criteria.

RESULTS

One hundred forty four patients were evaluated, 64.3% were anti-AQP4 antibody positive. Mean age at onset and disease duration were 31±12 and 7 ± 6 years respectively. Patients were predominantly female (4.7:1). Overall; relapsing course (80%) was more common than monophasic (20%). Optic neuritis was the most frequent presentation (48.6%), regardless of serostatus. The proportion of patients (54.3%) with visual acuity of ≤ 0.1 was higher in the seropositive group (p = 0.018). Primary presenting symptoms of transverse myelitis (TM) were observed in 29% of patients, and were the most significant correlate of hospitalization (p<0.001). Relative to anti-APQ4 serostatus, there were no significant differences in terms of age of onset, course, relapse rates or efficacy outcomes except for oligoclonal bands (OCB), which were more often present in seronegative patients (40% vs.22.5%; p = 0.054). Irrespective of serostatus, several disease modifying therapies were instituted including steroids or immunosuppressives, mostly, rituximab and azathioprine in the cohort irrespective of serostatus. The use of rituximab resulted in reduction in disease activity.

CONCLUSION

This is the first descriptive NMOSD cohort in the Arabian Gulf region. Seropositive patients were more prevalent with female predominance. Relapsing course was more common than monophasic. However, anti-AQP4 serostatus did not impact disease duration, relapse rate or therapeutic effectiveness. These findings offer new insights into natural history of NMOSD in patients of the Arabian Gulf and allow comparison with patient populations in different World regions.

Association Between Metacognition and Mood Symptoms Poststroke

INTRODUCTION

The link between metacognition and mood has been well established, particularly in other conditions with psychological comorbidity, however, there is no evidence regarding this association in the area of stroke.

AIM

The aim of this study was to examine the association between metacognition, based on the Self-Regulatory Executive Function model, and mood symptoms in the acute phase after stroke.

METHODS

One hundred thirty patients were recruited to a prospective stroke study in Bahrain, and n = 64 were assessed for mood and cognition. A neuropsychological battery of cognitive assessments included the following measures: the Mini-Mental State Examination, the Trail Making Test (A+B), and the Metacognition Questionnaire 30 (MCQ-30) for metacognition. The Hospital Anxiety and Depression Scale assessed mood symptoms, and stroke severity was measured using the National Institute of Health Stroke Severity Scale.

RESULTS

Total MCQ-30 scores were significantly associated with both anxiety (r = .47, P = .001) and depression (r = .54, P <. 0001). The MCQ-30 subscales' cognitive confidence, cognitive self-consciousness, and uncontrollability/danger were the specific factors to be associated with mood symptoms (P < .01). Global cognition (r =.32, P < .01), but not executive function, was significantly associated with depression only. Metacognition remained a statistically significant correlate with depression (β = .42, P < .0001) and anxiety (β = .51, P < .0001) after adjusting for education and global cognition.

DISCUSSION

Metacognition is a better determinant of mood symptoms after stroke, especially in regions where illiteracy levels are high in older populations, in comparison to executive function and global cognition.

Seizure control and improvement of neurological dysfunction in Lafora disease with perampanel

Lafora disease is a rare and fatal disease characterized by seizures, progressive cognitive and behavioral deterioration, as well as cerebellar dysfunction. Currently, there is no efficacious treatment that will control the seizures and improve the cognitive decline in this disease. We report a patient with Lafora disease who experienced a dramatic amelioration in her seizure frequency as well as the associated neurological and cognitive dysfunction following initiation of treatment with perampanel administered as monotherapy. Perampanel is the first potentially efficacious treatment for Lafora disease. We discuss a potential mechanism for the efficacy of perampanel in this disease.

Response of viral hepatitis B and C to interferon alpha treatment: Possible role of MGP-Positive lymphoid cells

Fifty-six needle liver biopsies from 28 patients with viral hepatitis B (15 cases) and hepatitis C (13 cases) treated with Interferon alpha for a minimum of six months were studied with the aim of determining the role of MGP-positive lymphoid cell infiltrates in the response to treatment with interferon. Besides assessing the MGP-positive cells, the following parameters were assessed and graded: (i) Inflammation in and around the portal tracts, (ii) fibrosis, nodularity and cirrhosis, (iii) piece-meal necrosis (inter-face hepatitis), (iv) lobular activity, (v) stainable iron. Sec-tions were stained with H&E, PAS, PASD, Perl, Masson Trichrome and MGP (Methyl Green Pyronin). All the parameters were graded 1 to 3 except stainable iron which was noted as present or absent.

Fourteen patients (50%) demonstrated histological evidence of a response to treatment. Seven of these showed a very pronounced response with the post treatment liver bi-opsies returning almost to normal. Five of the seven, 27.8% of all MGP stained cases and 71% of all brisk responses, contained ten or more MGP-positive lymphoid cells in the portal tracts.

In contrast, the non-responsive and worsened cases con-tained less than five MGP-positive cells as well as a pre-dominantly small mature lymphocytic infiltrate in the por-tal tracts.

Severity of piece-meal necrosis, lobular activity, portal tract inflammation, the presence or absence of stainable iron, were not of predictive value in the response of viral hepatitis to treatment with interferon alpha.

It appears that MGP-positive lymphoid cells, most prob-ably immune competent activated lymphoid cells, have a positive influence on, and are of predictive value for, the response to treatment of viral hepatitis B and C with inter-feron alpha.

Gynaecological malignancies in Qatar

Gynaecological malignancies constitute 6.88% (144 of 2092) of all malignant lesions in Qatar over a 15 year period (1979-1993). Cancer of the cervix was the most common with 54.86% followed by ovarian cancer 22.91%, endometrium 15.97%, vulva and vagina 2.75% and 2.08% respectively. Malignancies of the corpus uteri were rare. No tumours of the Fallopian tubes were registered during the study period. Early marriage, frequent coitus started early in life and increasing number of pregnancies were predisposing factors for the genesis of cancer of the cervix. As in some other developing countries, cervical and ovarian neoplasms tend to occur in the younger age group. Germ cell and gonadal stromal tumours were rare in Qatar and this may suggest rarity of these tumours in women of Arab and Indian subcontinent descent. Increasing number of pregnancies seems to protect against ovarian cancer. Abortions and age at menarche do not influence the incidence of gynaecological malignancies. Our findings provide an adequate data base for planning of gynaecological cancer education, screening programmes and resource allocation in Qatar.

Inflammatory pseudotumor of the spleen: a case report

An inflammatory pseudotumour of the spleen mimicking a lymphoma clinically is reported. Immunohistochemical studies and the characteristic polymophous inflammatory and fibroblastic infiltrates confirm the lesion as benign.

Effects of tetrahydro-9-aminoacridine on the electrocorticogram of rats with a unilateral lesion of the nucleus basalis magnocellularis

The effects of tetrahydro-9-aminoacridine (THA) were studied on the electrocortical activity of control rats and of rats with a unilateral lesion of the nucleus basalis magnocellularis (NBM) produced by alpha-amino-3-hydroxy-4-isoxozole propionic acid (AMPA). This lesion almost completely deprived the lesioned hemisphere of its cholinergic innervation. In control rats, THA (10 mg/kg i.p.) increased the amplitude of the slow components of the electrocorticogram (less than 9 Hz). These effects were antagonised by atropine (5 mg/kg i.p.). Lesion of the NBM alone decreased the amplitude of frequencies in the 12-16 Hz frequency band but did not significantly affect the slower frequencies. THA (10 mg/kg) restored the amplitude of the 12-16 Hz activity to the level seen in control rats before THA but did not affect activity in the other frequency bands. The results suggest that THA requires some residual cholinergic innervation in order to exert its effect.

Endobronchial tuberculosis manifested as obstructive airway disease in a 4-month-old infant

Tuberculosis is becoming a more prominent pediatric disease, but there are few recent reports of endobronchial involvement. We have presented the case of a 4-month-old infant with symptomatic obstructive airway disease due to Mycobacterium tuberculosis. Endobronchial tuberculosis usually follows 2 to 3 months of antituberculous therapy. This case is especially unusual because the endobronchial disease developed before diagnosis or therapy. Endobronchial tuberculosis should be considered in any patient with symptoms or roentgenographic findings of obstructive airway disease. Bronchoscopy is the best technique for diagnosis and follow-up of endobronchial tuberculosis.
