Neurocognitive correlates of metabolic dysregulation in individuals with mood disorders: a systematic review and meta-analysis

Individuals with mood disorders are predisposed to metabolic dysfunction, while those with metabolic dysregulation such as diabetes and obesity experience more severe depressive symptoms. Both metabolic dysfunction and mood disorders are independently associated with cognitive deficits. Therefore, given their close association, this study aimed to explore the association between metabolic dysfunction in individuals with mood disorders in relation to cognitive outcomes. A comprehensive search comprised of these three domains was carried out; a random-effects meta-analysis pooling mean cognitive outcomes was conducted (PROSPERO ID: CRD42022295765). Sixty-three studies were included in this review; 26 were synthesized in a quantitative meta-analysis. Comorbid metabolic dysregulation was associated with significantly lower global cognition among individuals with mood disorders. These trends were significant within each mood disorder subgroup, including major depressive disorder, bipolar disorder, and self-report depression/depressive symptoms. Type 2 diabetes was associated with the lowest cognitive performance in individuals with mood disorders, followed by peripheral insulin resistance, body mass index ⩾25 kg/m2, and metabolic syndrome. Significant reduction in scores was also observed among individual cognitive domains (in descending order) of working memory, attention, executive function, processing speed, verbal memory, and visual memory. These findings demonstrate the detrimental effects of comorbid metabolic dysfunction in individuals with mood disorders. Further research is required to understand the underlying mechanisms connecting mood disorders, metabolism, and cognition.

Primary prevention of venous thromboembolism for cancer patients in randomized controlled trials: a bibliographical analysis of funding and trial characteristics

Background

The majority of randomized controlled trials (RCTs) investigating venous thromboembolism (VTE) prophylaxis in patients with cancer involve commercial sponsorship. Commercial sponsorship overcomes feasibility limitations inherent in RCTs, such as recruitment and funding, but has attracted scrutiny for its potential for bias.

Objectives

In RCTs of VTE prophylaxis in patients with cancer, how do trial characteristics compare between commercially sponsored RCTs and noncommercially sponsored RCTs?

Methods

Medline, Embase, and Cochrane Central Register of Controlled Trials were searched for RCTs that investigated at least 1 pharmacologic intervention for VTE prophylaxis in adult patients with cancer. Screening and data extraction were conducted by independent reviewers. Outcomes included trial characteristics, reporting of favorable outcomes, protocol-manuscript discrepancies, and appraisal of spin. Outcomes were compared using the independent t-test, Mann-Whitney U-test, Pearson chi-squared test, and Fisher's exact test. Logistic regression was performed to identify factors associated with possible bias.

Results

Of the 54 trials analyzed, 34 (63%) reported commercial sponsorship. Commercial sponsorship was not associated with the reporting of favorable outcomes, presence of spin, retrospective registration, or protocol-manuscript discrepancy. Spin was most prevalent in the abstract conclusions (9 out of 17 [53.3%]) and manuscript conclusions (8 out of 17 [46.7%]).Commercially sponsored trials had a higher rate of intention-to-treat analysis. Noncommercially sponsored trials were more likely to report retrospective registration of trial protocol and the use of composite primary outcomes.

Conclusion

There were few significant differences between trial characteristics, suggesting that the evidence from commercially sponsored trials investigating VTE prophylaxis in patients with cancer is unlikely to be subject to bias attributable to commercial sponsorship.

A reflection on the use of Antidepressants to manage agitation in dementia

Introduction

Agitated behaviors is a common neuropsychiatric symptom (NPS) in dementia, defined as inappropriate verbal, vocal, or motor activity that is not thought to be caused by an unmet need. It is frequently reported as a major problem, that impairs the quality of life for the elderly themselves and for caregivers. There has been increasing interest in the use of sedative antidepressants to treat NPS due to concerns over the safety and efficacy of antipsychotics in this setting.

Objectives

We aim to review clinical evidence of alternatives to antipsychoticst to manage agitation in dementia.

Methods

We conduct a non-systematic review of recent evidence on dementia and agitation, using PubMed/Medline database.

Results

Although non-pharmacological interventions are the first-line treatment for agitation, it is a legitimate target for therapeutic intervention and according to previous guidelines, antipsychotic are among the most used drugs, albeit restricted because of side-effects. A substitution strategy to avoid antipsychotic prescription was highly considered, however there is limited evidence to support the use of antidepressants as a safe and effective alternative for agitation in dementia. Studies compare Mirtazapine, Selective serotonin reuptake inhibitors (SSRIs) and Trazodone and a reduced benefit in mortality is observed. However, citalopram was more effective were more likely outpatients for moderately agitation and Mirtazapine reveals being potentially harmful, in different studies.

Conclusions

Moving forward, a greater understanding of NPS neurobiology, will help to clarify the efficacy of Antedepressants for the treatment of agitation in dementia. Benefits an also the patient and caregiver preference should be kept in mind.

Sexuality among elderly patients with dementia: Are we aware of their needs?

Introduction

Sexuality is one of the basic needs in human life and its positive effects for the wellbeing are undeniable. People with dementia, despite cognition and functioning impairments, still pursue intimacy as part of their expression of basic human instincts.

Objectives

We aim to address the subject of sexuality among patients with dementia, emphasizing the physiological, environmental and legal barriers.

Methods

We conduct a non-systematic review of recent evidence on dementia and sexuality, using PubMed/Medline database.

Results

People with dementia face several difficulties expressing their sexuality. First, they struggle with physiological barriers to enjoyment of sexuality, such as ageism, apathy and limited free mobility. Secondly, either at home or in long-term care facilities, privacy is usually abolished. For care facilities, the Sexuality Assessment Tool supports the normalization of sexuality and self-audit policies that promote resident rights for privacy and assistance. Moreover, expression of sexuality in elderly can be misinterpreted as disinhibition, leading to unnecessary use of psychotropics to cease these behaviors. Additionally, legal barriers regarding consent arise when a partner loses the ability to consent sexual activity, questioning agreement and mutual desire. The Lichtenberg and Strzepek Decision Tree for Capacity to Participate in Intimate Relationships can be helpful to address this issue.

Conclusions

Sexuality in older people remains neglected in clinical intervention. Besides the urgent need to deconstruct stereotypes, families and staff must be sensitized to understand the changes in expression and perception of sexuality among people with dementia, rather than being indifferent or medicate what can be perceived as disinhibited/distorted expressions of normal needs.

Self-perceived functional impairment or disability in Delusional Disorder – Case Reports

Introduction

Delusional disorder (DD) is a psychotic disorder with an estimated prevalence of less than one percent,traditionally characterized by systematized delusional ideas with no cognitive deterioration.However, some studies have been reporting impairment of neurocognitive system (social cognition,learning and memory, expressive language,complex attention, executive function) that might have an impact functionality both in social and work domains..

Objectives

This work aims to review clinical evidence on self-perceived functional impairment or disability in DD and to present two clinical cases evaluated at a psychiatric unit.

Methods

We report two clinical cases based on patients’ history and clinical data, and reviewed clinical records using PubMed® database with search terms of “Delusional Disorder”,“Cognition Impairment in Persistent DD”.

Results

We present two clinical cases of patients who were admitted to psychiatric unit after developing psychotic symptoms namely persecutory delusions about neighbors.A persistent delusional disorder was established and antipsychotic treatment was initiated.The 74-years-old men presented deficits in executive and memory processes; ended up institutionalized after two months of being discharged.The 47-years-old woman, despite remaining as a lawyer, noticed a decrease in work capacity and so she ended up being responsible for less demanding cases.Cases of delusional disorder showed a poor performance in most cognitive tests and some of the cognitive deficits seem to affect functionality namely memory, expressive language and attention.

Conclusions

Although classical literature has not systematized an association between DD and personality deterioration,there are some evidences of loss of functionality and cognitive commitment in this disorder.This suggests the importance of cognitive interventions to improve functional prognosis in this clinical population.

From kraepelin to the present. Dementia praecox – a case study

Introduction

In the late XIX^th century Kraepelin described a new nosologic division for the psycothic disorders – Paranoia and Dementia Praecox. He emphasized that dementia praecox is a central nervous system disease, involving permanent lesions on cerebral cortex. Besides biological deterioration, it appears as the result of psychic degenerative process. From the mid-20th century onward, antipsychotic drugs had been robustly generalized, and in parallel to the current classifications, residual symptoms in schizophrenia tend to be rare but still prevail in our patients.

Objectives

The aim of our work is to report a clinical case of residual schizophrenia in parallel with the classic classification of Dementia Praecox and also do an overview of this disorder and its historical perspective.

Methods

We conducted clinical interviews with the patient and family members, reviewed clinical records and conducted a query in the MEDLINE database using the terms " Dementia Praecox ", “Psychosis”, “Paranoia”, “Kraepelin”, “History”.

Results

We present the clinical case of a 74-year-old man with onset of psychotic symptoms on his twenties and diagnosed with Schizophrenia. In the past years, after acute psychotic episodes it was increasingly difficult to return to prior levels of functioning. Currently, he was brought to psychiatric emergency ward presenting bizarre behavior, stereotyped movements and speech disturbances, which reveal disorganized thinking and inability to express his emotions.

Conclusions

Although these syndromes are nowadays relatively rare, it is important to keep them in mind, in order to understand the natural progression of psychotic diseases, improve their rehabilitative treatment and prognosis.

Hepatitis C treatment outcome in former or current intravenous drug users coinfected with HIV, with or without directly observed therapy

BACKGROUND

Intravenous drug users (IDUs) with hepatitis C virus (HCV)/human immunodeficiency virus (HIV)-coinfection are recognised as a high-risk, vulnerable group.

METHODS

Between February 2015 and April 2018, a single-centre, non-interventional cohort study was conducted in an outpatient setting, to evaluate the sustained virologic response (SVR12) and assess treatment uptake models. The study included 385 former or recent IDUs divided into two groups: A-without use of opioid substitution treatment (OST) and B-patients taking opioid substitution; patients in group B received OST and self-administered therapy (B1) or OST and therapy under DOT (B2). Patients were characterised by demographic and clinical features and compared for treatment response. Correlations between SVR12 and independent variables were determined by logistic regression.

RESULTS

Patients were mostly males (88.3%) with a mean age of 46 ± 5 years and HCV genotype 1a (63.7%). Approximately 28% were treatment-experienced and 84.9% received sofosbuvir/ledipasvir. The mean CD4⁺T count was 649 cells/mm³, and most individuals were on antiretroviral therapy with undetectable viral loads (97.4%). SVR12 was achieved in 94.8%, and only eight patients relapsed. No significant differences were found in treatment effect between individuals taking opioid substitutes under different treatment models. Correlations were found between HCV viral response and both HIV suppression and albumin levels.

CONCLUSIONS

IDU with HCV/HIV coinfection, including individuals on self-administration of HCV therapy and opioid substitution treatments or in DOT programmes, are no longer considered a difficult-to-treat group, as they achieve high rates of SVR12.

Human papilloma virus genotypes in dysplasia and epithelial hyperplasia of oral cavity using the luminex xmap technology. A multicenter study

Background

Oral cancer associated with high risk (HPV-HR) human papilloma virus (HPV) has been increasing. HPV-HR has been associated with epithelial dysplasia, however, little information exists on its frequency in epithelial hyperplasia lesions. The aim of this study is to compare HPV genotypes in dysplastic and hyperplastic lesions of oral cavity.

Material and Methods

Two hundred and fifty oral lesions: 131 dysplasia and 119 hyperplasia from two regions of Colombia were evaluated. One hundred seventy-four coming from urban area and 104 from a high risk population to oral cancer from a rural area. HPV was identified by qPCR and Twenty-four HPVs genotypes were evaluated by Luminex® technology. Logistic regressions were performed to establish the associations between HPV infections with oral dysplasia.

Results

Twenty-eight percent (70/250) of the samples were positives for any HPV and HPV-HRs were more frequently than low risk HPVs. HPV-16 was the most detected genotype (16%) followed by HPV-31, 53, 18 and 45. HPV, HPV-HRs and HPV-16 were only associated with dysplasia in urban area; OR 3.28 (CI 95% 1.49-7.17), OR 7.94 (CI 95% 2.97-21.2) and OR 5.90 (CI 95% 2.05-17). Individuals in rural area showed more HPV and HPV-HRs infection in hyperplasic lesions than urban population. The majority of HPV+ lesions had multi-type of HPV (52/70) and the urban individuals showed more genotypes than rural population.

Conclusions

HPV-.HRs are frequently found in hyperplastic and dysplastic epithelial lesions. HPV-HRs and HPV-16 were associated with dysplasia in urban population. Rural high risk population and urban population differ in the frequency and variety of HPV genotypes.

Key words:Human papilloma virus, epithelial dysplasia, epithelial hyperplasia, HPV-genotypes.

Fertilidade de carneiros de raça Saloia com sémen refrigerado ou congelado

Avaliaram-se as fertilidades e coeficientes de variação (CV) de carneiros Saloios após inseminação artificial (IA) por via cervical com sémen refrigerado (SR) ou congelado (SC). Na 1ª experiência avaliou-se o efeito de duas épocas de IA (primavera vs. outono) sobre a fertilidade, utilizando SR (n=5 carneiros) e de duas épocas de congelação de sémen (outono vs. inverno) sobre a fertilidade de ovelhas inseminadas na primavera utilizando SC (n=3 carneiros). Nas outras experiências avaliaram-se as variações da fertilidade de carneiros, independentemente das épocas de IA ou congelação, utilizando SR e SC (2ª experiência: 4 carneiros comuns; 3ª experiência: 16 e 5 carneiros, respectivamente). Não foram observadas diferenças na fertilidade entre épocas de IA ou congelação de sémen. As fertilidades obtidas com SR foram superiores às do SC (2ª experiência: 51,28 vs. 13,65 %; 3ª experiência: 48,51 vs. 13,04 %). Os CV da fertilidade utilizando SC foram superiores aos do SR (2ª experiência: 41,3 % vs. 13,1 %; 3ª experiência: 38,9 vs. 19,5 %). Os carneiros de raça Saloia podem ser utilizados em programas de IA com SR e SC nas épocas do ano estudadas sem diminuição da fertilidade. O SC originou CV para a fertilidade superior sugerindo diferentes susceptibilidades dos carneiros à congelação.

[A rare case of hyperandrogenism: bilateral Leydig cell tumor of the ovary]

BACKGROUND

The androgen-secreting tumors constitute fewer than 1% of ovarian tumors. Leydig cell tumor is one of the most common of this type of lesion and it is usually benign, small and unilateral.

CASE REPORT

A 67 year old woman was referred to the Endocrine clinic due to hirsutism (score 22 Ferriman-Gallwey) and male type alopecia with 3 years of evolution and progressive worsening. Biochemically she had high levels of serum testosterone - 662 ng/dl (N < 62 ng/dl). Transvaginal ultrasonography and abdomen-pelvic CT scan didn't show any signs of adrenal or ovarian tumors. Bilateral oophorectomy was performed and histopathologic exam revealed bilateral Leydig cell tumors, measuring 1cm each. Four months after surgery, the patient had a marked improvement of the signs (score 3 Ferriman-Gallwey) and normalized testosterone levels (35.9 ng/dl).

DISCUSSION

Androgen-secreting tumors are rare, but they should be excluded in cases of rapid onset of virilization and elevated androgen levels. Tumors are frequently undetectable by imaging techniques because of their small dimensions, exploratory surgery by a skilled team is frequently necessary and is often the best treatment for the majority of these cases. In this case report we present a rare case of bilateral Leydig cell tumor. Only five cases have been reported in the literature.The clinical history and the elevated levels of testosterone had suggested the presence of an androgen-producing tumor, despite the difficulty of the diagnosis on imaging techniques. Due to the fact that our patient was in a post-menopausal stage, we decided that the appropriate treatment would be bilateral oophorectomy. The histopathologic disclosed the diagnosis and allowed the patient's cure.

[A case of epilepsy simulating a pheochromocytoma]

INTRODUCTION

Autonomic epilepsy is a rare entity that results from an epileptogenic focus involving certain structures belonging to the autonomous nervous system; it is characterised by the occurrence of convulsive seizures that consist in autonomic phenomena.

CASE REPORT

We report the case of a 28-year-old female patient who suffered paroxysmal episodes similar to those accompanying a pheochromocytoma. Following a thorough examination, both the presence of a tumour and the anomalous production of catecholamines were excluded and, although it was not possible to provide electroencephalographic evidence, the patient was diagnosed as suffering from autonomous epilepsy, which was later confirmed by the clinical efficacy of valproic acid therapy.

CONCLUSIONS

Autonomic seizures often show characteristics that are singular or similar to those of other clinical entities. This makes the disorder difficult to diagnose and sometimes requires therapeutic testing with anticonvulsive drugs.

Multiple dose vaccination against childhood diseases: high coverage with the first dose remains crucial for eradication

The high vaccination coverage required to eradicate communicable diseases like measles, mumps and rubella, with a single dose of vaccine, has prompted many countries to introduce a second dose. In this paper we investigate the conditions to eradicate childhood diseases with multiple doses of vaccine by obtaining explicit analytical solutions to the classical compartment model that assumes an age-independent force of infection and conceptualizes the host population as divided into maternally protected (P), susceptibles (S), latents (E), infectious (I), and removed (R). The solutions allow a quantitative discussion of the long-term impact of vaccination schedules with an arbitrary number of doses of vaccine. It becomes possible to determine the effect of the number of doses, ages at vaccination, and coverage rates of vaccines against childhood diseases. In an example with a two-dose vaccination schedule against measles, we show that, in spite of a second dose, a high (> 90%) immunization coverage in the first dose is still crucial to achieve eradication. With a high first-dose coverage, however, eradication is relatively insensitive to the age of the second dose and requires only moderate coverage rates in the latter.
