Long-term trajectories of densely reported depressive symptoms during an extended period of the COVID-19 pandemic in Switzerland: Social worries matter.

Previous mental health trajectory studies were mostly limited to the months before access to vaccination. They are not informing on whether public mental health has adapted to the pandemic. The aim of this analysis was to 1) investigate trajectories of monthly reported depressive symptoms from July 2020 to December 2021 in Switzerland, 2) compare average growth trajectories across regions with different stringency phases, and 3) explore the relative impact of self-reported worries related to health, economic and social domains as well as socio-economic indicators on growth trajectories. As part of the population-based Corona Immunitas program of regional, but harmonized, adult cohorts studying the pandemic course and impact, participants repeatedly reported online to the DASS-21 instrument on depressive symptomatology. Trajectories of depressive symptoms were estimated using a latent growth model, specified as a generalised linear mixed model. The time effect was modelled parametrically through a polynomial allowing to estimate trajectories for participants' missing time points. In all regions level and shape of the trajectories mirrored those of the KOF Stringency-Plus Index, which quantifies regional Covid-19 policy stringency. The higher level of average depression in trajectories of those expressing specific worries was most noticeable for the social domain. Younger age, female gender, and low household income went along with higher mean depression score trajectories throughout follow-up. Interventions to promote long-term resilience are an important part of pandemic preparedness, given the observed lack of an adaptation in mental health response to the pandemic even after the availability of vaccines in this high-income context.

Trajectories of depression, anxiety and stress among adults during the COVID-19 pandemic in Southern Switzerland: the Corona Immunitas Ticino cohort study.

OBJECTIVES: Using longitudinal data from Southern Switzerland we assessed ten-month temporal trajectories of moderate to severe depression, anxiety and stress among adults after the first pandemic wave and explored differences between sociodemographic and health status groups. STUDY DESIGN: This was a population-based prospective cohort study. METHODS: Participants were 732 (60% women) adults aged 20-64 years who completed the Depression, Anxiety and Stress Scale on a monthly base since August 2020 until May 2021, as part of the Corona Immunitas Ticino study based on a probability sample of non-institutionalized residents in Ticino, Southern Switzerland. RESULTS: Prevalence of moderate to severe depression increased from 7.5% in August 2020 to 12.5% in May 2021, anxiety increased from 4.8% to 8.1% and stress increased from 5.5% to 8.8%. A steeper increase in poor mental health was observed between October 2020 and February 2021. Men had a lower risk for anxiety (odds ratio [OR] = 0.58, 95% confidence interval [CI] = 0.36-0.95) and stress (OR = 0.61, 95% CI = 0.44-0.95) than women. Suffering from a chronic disease increased the risk for depression (OR = 1.82, 95% CI = 1.12-2.96), anxiety (OR = 2.38, 95% CI = 1.44-3.92) and stress (OR = 1.87, 95% CI = 1.14-3.08). The differences between these groups did not vary over time. CONCLUSIONS: In a representative Swiss adult sample, prevalence of moderate to severe depression, anxiety and stress almost doubled in the course of ten months following the end of the first pandemic wave in spring 2020. Women and participants with pre-existing chronic conditions were at a higher risk of poor mental health.

A systematic review and meta-analysis of dementia prevalence in seven developing countries: A STRiDE project.

The STRiDE project sets out to support the development of effective dementia policy in middle-income countries (Brazil, India, Indonesia, Jamaica, Kenya, Mexico, and South Africa). As part of this it will generate new data about the prevalence of dementia for a subset of these countries. This study aims to identify the current estimates of dementia prevalence in these countries and where the gaps lie in the current literature. A systematic review was completed on 30th April 2019 across electronic databases, identifying dementia prevalence literature originating from any of the seven countries. Four hundred and twenty-nine records were identified following de-duplication; 28 studies met the inclusion criteria and were included in the systematic review. Pooled estimates of dementia prevalence ranged from 2% to 9% based on DSM-IV criteria; these figures were generally higher in studies using other diagnostic criteria (e.g. the 10/66 algorithm). Available prevalence data varied between countries. Only Brazil, Mexico and India had data derived from studies judged as having a low risk of bias. Irrespective of country, studies often were not explicit in detailing the representativeness of their sample, or whether there was non-response bias. Further transparent and externally valid dementia prevalence research is needed across the STRiDE countries.

Experience of stigma and discrimination in families of persons with schizophrenia in the Czech Republic.

RATIONALE: Mental health-related stigma and discrimination not only affect persons living with schizophrenia but also their whole families. Stigma and discrimination reduction is key to respond to the unmet needs of persons with mental illness. The local context is of particular importance in this endeavor, as stigma and its manifestations depend on the specific conditions of the target population and across cultures and settings. Evidence on effective approaches to reduce stigma is sparse and lacking from Central and Eastern Europe, including from the Czech Republic. OBJECTIVE: Our aim was to inform an anti-stigma campaign undertaken in the framework of the national mental health reform in the Czech Republic. METHODS: We conducted a qualitative study based on semi-structured in-depth interviews with relatives of patients diagnosed with schizophrenia in the Czech Republic. Initial respondents were identified through local mental health services and users' organizations with a consecutive chain-referral sampling. Transcribed narratives were thematically analyzed within a pre-developed four-level thematic framework to comprehensively identify experiences of stigma and discrimination in all areas of the respondents' lives. RESULTS: Stigma experiences of 25 diverse family members of persons living with schizophrenia spanned four levels of respondents' lives (macro-, meso-, micro-, and intro-level). The overarching issues were: (1) general lack of understanding and misconceptions about mental illness; (2) structural discrimination and paucity of governmental and public support system; (3) burden of "pervasive and unlimited" care and inability of independent living. CONCLUSIONS: We identified several features of mental health related stigma and the ensuing discrimination in Czech Republic experienced by persons with severe mental illness and their relatives. We developed a set of recommendations for policy-makers aimed at reducing ignorance and prejudice amongst the public and professionals, improving health and social services-including employment, housing and community integration-and the provision of family support.

Advanced epidemiologic and analytical methods.

Observational studies are indispensable for etiologic research, and are key to test life-course hypotheses and improve our understanding of neurologic diseases that have long induction and latency periods. In recent years a plethora of advanced design and analytic techniques have been developed to strengthen the robustness and ultimately the validity of the results of observational studies, and to address their inherent proneness to bias. It is the responsibility of clinicians and researchers to critically appraise and appropriately contextualize the findings of the exponentially expanding scientific literature. This critical appraisal should be rooted in a thorough understanding of advanced epidemiologic methods and techniques commonly used to formulate and test relevant hypotheses and to keep bias at bay.

Herpes Zoster: the rationale for the introduction of vaccination in Italy.

Herpes Zoster (HZ) and its main complication, post-herpetic neuralgia (PHN), represent an important public health issue because of their relevant burden within older adult population and the actual suboptimal therapeutic management of the diseases. Incidences of HZ and PHN are comparable all over the world and are closely related with the population age. Epidemiological data collected in Italy about HZ and its complications confirmed the trend registered in North America and Europe. Moreover HZ related burden is exacerbated by a significant economic impact related to both direct and indirect costs. Since 2006 a live, attenuated varicella zoster virus vaccine, that contains VZV Oka strain [Zostavax, Merck & Co., Inc.], was licensed for the prevention of HZ and PHN in adults aged ≥ 60 years. Since 2011, the licensure has been extended to adults between 50 and 59 years. The vaccine has demonstrated a good immunogenicity, efficacy and safety profiles in two pivotal phase III clinical trials and the effectiveness was further confirmed after vaccine licensure. Pharmaco-economic studies concluded that HZ vaccine is cost-effective in most European countries and generally supported the economic value of this vaccination. The vaccine is actually recommended in USA, Canada and several European countries. The opportunity to reduce the burden of these diseases by the recommendation of HZ vaccination have been evaluated and suggested also in our Country and some Regions have been recently introduced the vaccine in their immunization plan. If the good results, already obtained with HZ vaccine in other countries, will be confirmed by these Italian pilot experiences, vaccination programs should be made uniform in all Country in order to ensure an equitable offer of this important preventive tool.

Intentional weight loss in overweight and obese individuals and cognitive function: a systematic review and meta-analysis.

High adiposity in middle age is associated with higher dementia risk. The association between weight loss and cognitive function in older adults is still controversial. A meta-analysis was undertaken to estimate the effectiveness of intentional weight loss on cognitive function in overweight and obese adults. A structured strategy was used to search randomized and non-randomized studies reporting the effect of intentional and significant weight loss on cognitive function in overweight and obese subjects. Information on study design, age, nutritional status, weight-loss strategy, weight lost and cognitive testing was extracted. A random-effect meta-analysis was conducted to obtain summary effect estimates for memory and attention-executive domains. Twelve studies met inclusion criteria. Seven were randomized trials and the remaining five included a control group. A low-order significant effect was found for an improvement in cognitive performance with weight loss in memory (effect size 0.13, 95% CI 0.00-0.26, P=0.04) and attention/executive functioning (effect size 0.14, 95% CI 0.01-0.27, P<0.001). Studies were heterogeneous in study design, sample selection, weight-loss intervention and assessment of cognitive function. Weight loss appears to be associated with low-order improvements in executive/attention functioning and memory in obese but not in overweight individuals.

Application of intraoperative indocyanine green angiography for CNS tumors: results on the first 100 cases.

PURPOSE: To investigate the application of indocyanine green (ICG) videoangiography during microsurgery for central nervous system (CNS) tumors. METHODS: One hundred patients with CNS tumors who underwent microsurgical resection from December 2006 to December 2008 were retrospectively analyzed. The diagnosis was high grade glioma in 54 cases, low grade in 17 cases, meningioma in 14 cases, metastasis in 12 cases and hemangioblastoma in 3 cases. Overall, ICG was injected intraoperatively 194 times. The standard dose of 25mg of dye was injected intravenously and intravascular fluorescence from within the blood vessels was imaged through an ad hoc microscope with dedicated software (Pentero, Carl Zeiss Co., Oberkochen, Germany). Pre-resection and post-resection arterial, capillary and venous ICG videoangiographic phases were intraoperatively observed and recorded. RESULTS: ICG videangiography allowed for a good evaluation of blood flow in the tumoral and peritumoral exposed vessels in all cases. No side effects due to ICG were observed. CONCLUSIONS: ICG video-angiography is a significant method for monitoring blood flow in the exposed vessels during microsurgical removal of CNS tumors. Pre-resection videoangiography provides useful information on the tumoral circulation and the pathology-induced alteration in surrounding brain circulation. Post-resection examination allows for an immediate check of patency of those vessels that are closely related to the tumor mass and that the surgeon does not want to damage.

Increased fructose intake as a risk factor for dementia.

The transition in the world age demographic toward older age is associated with an increased risk of neurodegenerative diseases, such as Alzheimer's disease. Risk profiles for dementia may also be changing. Obesity and type 2 diabetes have increased in prevalence in the last half-century and have been associated with increased dementia risk. Specific changes in nutrition may also represent a direct risk. A diet transition in the United States has occurred in the intake of refined sugar, particularly high-fructose corn syrup (HFCS) from a yearly estimate of 8.1 kg/person at the beginning of the XIX century to a current estimate of 65 kg/person. This article considers the association between refined sugar intake, markers of cardiovascular disease risk, and the possible promotion of the development of dementia.

Endoscopic radial artery harvesting for U-clip EC-IC bypass in the treatment of a giant petrous internal carotid artery aneurysm: technical case report.

INTRODUCTION: High-flow extracranial-intracranial (EC-IC) bypass and aneurysm trapping constitutes a well-known surgical solution for internal carotid artery (ICA) aneurysms that are not amenable to clip ligation or endovascular therapy. The advantages of the radial artery (RA) as a conduit for myocardial revascularization have become widely accepted, with a better patency rate than that of the saphenous vein. CASE REPORT: A 66-year-old woman was found to harbour a right giant, partially thrombosed aneurysm of the intrapetrous segment of the internal carotid artery. Endoscopic harvesting of the RA was achieved combining a resterilizable retractor and a vessel sealing system. After neck dissection, the main trunk of the middle cerebral artery (MCA), its branches, and part of the aneurysm were isolated through a right fronto-orbito-zygomatic craniotomy. The external carotid artery, distal to the origin of the facial artery, was chosen in the neck for an end-to-end microanastomosis. The temporal branch of the MCA was selected for an end-to-side microanastomosis with the radial graft using ten U-clips. The total temporary occlusion time was 13 min. The post-operative course was uneventful. CONCLUSION: Endoscopic technique provides improved patient satisfaction, especially in terms of length of the surgical incision, when compared to the conventional approach. Combined with the innovative use of U-clips, this case illustrates how new technologies can simplify ECA-ICA bypass surgery while yielding a better cosmetic and functional outcome.

Endoscopic radial artery harvesting for U-clip high-flow EC-IC bypass: technical report.

INTRODUCTION: Bypass and aneurysm trapping constitute a well-known surgical solution for aneurysms that are not suitable for clipping or coiling. New techniques are available that make EC-IC bypass procedures easier, safer and, possibly, less invasive. The nitinol self-closing U-Clip device (Medtronic, Inc., Minneapolis) has been designed to facilitate the interrupted suture technique by eliminating the need for suture management, knot tying, and surgical assistance. MATERIALS AND METHODS: We present two consecutive U-clip bypass procedures in which the radial artery graft was harvested endoscopically. RESULTS: This novel bypass technique employs endoscopy to minimise arm injury due to radial artery harvesting and self-closing U-clips to simplify the intracranial micro-anastomosis and reduce the temporary occlusion time. Angiography confirmed bypass patency in all patients. DISCUSSION: Combined with the innovative use of U-clips, these two examples illustrate how new technologies can simplify EC-IC bypass surgery while yielding a better cosmetic and functional outcome.

Gravity-aided trans-falcine removal of a contralateral subcortical ependymoma.

The transfalcine approach is a variant of the interhemispheric approach which provides exposure of the medial surface of the contralateral hemisphere through a falx incision. Gravity can be used as a natural retractor. We report a 32-year-old woman with an ependymoma of the medial surface of the left Rolandic area that was completely removed through a contralateral gravity-aided, image-guided transfalcine approach. The contralateral transfalcine approach can be a good option for lesions presenting at the interhemispheric fissure especially those associated with perilesional oedema and avoids the risks of a transparenchymal dissection and retraction of a swollen hemisphere.

[Communicating with patients: how good are our pamphlets and other written materials? An evaluation of the quality of the written information available to patients with asthma and diabetes in out-patients' clinics in Milan]. / Comunicazione medica scritta: costruiamo informazioni di qualità per il paziente? Una valutazione della qualità del materiale informativo a disposizione dei pazienti asmatici e diabetici negli ambulatori milanesi.

OBJECTIVES: 1) To identify the extent and the nature of information pamphlets available for asthmatic and diabetic patients in secondary care hospitals in Milan; 2) To investigate what patients think about the quality of pamphlets using a questionnaire developed ad hoc. METHODS: Pamphlets have been identified by contacting 8 specialised ambulatory hospitals. The questionnaire was developed to achieve a quality rate in 3 dimensions of the materials (Style and readability, The condition and Treatment options). Patients were recluted in the same ambulatory hospital. RESULTS: 4 ambulatory hospitals and 40 patients agreed to participate in our survey. We identified 8 pamphlets (5 diabetes, 3 asthma). 6 of these have been promoted byfarmaceutical companies. The mean length was 31 pages and the issue most covered was treatment options (33% of pages dedicated). 30 pages (12% of the total) presented with publicity advertisements (6% direct and 6% indirect). The dimension with the best satisfaction rate was Condition, followed by Style and readability. CONCLUSIONS: In Milan, in secondary care asthmatic and diabetic patients, are often invited to consult pamphlets. They positively judged this material. During the study ambulatory physicians were poorly attentive about problems concerning patient access to information.

C282Y mutation and hepatic iron status in hepatitis C and cryptogenic cirrhosis.

BACKGROUND: Increased iron deposition in liver is seen in both primary and secondary hemochromatosis. However, it is not uncommon to see significant iron deposition in a liver biopsy, explant, or autopsy specimen without any significant clinical risk factor. Because of the discovery of the candidate gene (HFE) for hereditary hemochromatosis, we may now be able to screen high-risk patient populations for the abnormal mutation (C282Y). MATERIALS AND METHODS: In this study we analyzed the livers of 50 transplant patients with a diagnosis of either hepatitis C cirrhosis or cryptogenic cirrhosis for the prevalence of the more common C282Y mutation of the HFE gene and correlated the findings to hepatic iron concentration. RESULTS: Of the 26 cases of hepatitis C cirrhosis, 3 were found to be heterozygous for the C282Y mutation. Of the 22 cases of cryptogenic cirrhosis, 1 was found to be heterozygous for the C282Y mutation. Stainable iron was increased in hepatitis C cirrhosis (76.9%) as compared to cryptogenic cirrhosis (50%) (P =. 05). Of the 3 heterozygotes with hepatitis C cirrhosis, 2 showed hepatic iron concentrations of 3+ and 4+, and 1 showed 1+. CONCLUSIONS: We conclude that patients with hepatitis C have an increased tendency to accumulate iron in the liver, and mutations in the HFE gene play a minor role in hepatic accumulation of iron in these patients.

Semantic category dissociations, familiarity and gender.

We carried out four experiments to assess the extent to which familiarity with certain objects in everyday life is related to gender and can account, at least partially, for the semantic category dissociation observed in a few brain-damaged patients. In the first experiment, 210 normal subjects, half males and half females, were given the names of 60 stimuli from the Snodgrass and Vanderwart's set, 30 belonging to living categories and 30 to non-living categories. The task was to rate their familiarity, based on the frequency with which one (i) thinks or speaks of a given item, (ii) sees it represented in the media, and (iii) is confronted with real exemplars. The three indices were highly correlated and their average value was, therefore, used. Females gave higher familiarity ratings to fruit, vegetables and furniture and males to tools. The second experiment was aimed to verify whether the gender difference was responsible for the category dissociation found following brain damage. A male patient with greater impairment for living categories and a female patient with greater impairment for non-living categories were requested to name the same 60 stimuli and their scores were analysed, partialling out the familiarity effect, measured both with the non-gender specific index of Snodgrass and Vanderwart and with the new gender-specific index. In either case, the category dissociation remained significant. To determine if the mean general population familiarity index was valid for the single subject, we studied whether a cohabitant first degree relative was able to predict a normal subject's familiarity better than the population index. Contrary to expectations, the better predictor was the population index. The test-retest reliability of each subject's familiarity ratings was satisfactory, but not higher than the correlation between the personal judgement of each subject and the population index.

Splenic smooth-muscle tumors in children with acquired immunodeficiency syndrome: report of two cases of this unusual location with evidence of an association with Epstein-Barr virus.

Smooth-muscle neoplasms are rarely located in the spleen. They have been previously reported in five cases of children with human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS). Two cases of children with HIV infection/AIDS with autopsy and surgical pathology evidence of multiple smooth-muscle neoplasms with splenic involvement are presented. DNA was extracted from histology slides in both cases for analysis for Epstein Barr (EB) virus. In both cases, the presence of EB virus was confirmed. This paper documents two additional cases of the unusual phenomenon of splenic involvement by smooth-muscle neoplasms in the setting of AIDS in childhood and further supports the role of EB virus in the development of these neoplasms.

Prevalence of factor V Leiden in African-Americans.

Factor V Leiden (FVL) refers to a mutation on the clotting factor, Factor V. Protein C is a factor involved in the fibrinolytic pathway. Activated protein C (APC) normally degrades activated Factor V. The presence of the Leiden mutation on Factor V makes this protein resistant to degradation by APC, leading to a hypercoagulable state. Previous studies reported a prevalence of FVL in various populations between 0-6% and absent in Africans. We studied two factor V alleles from one hundred random blood samples submitted for CBC. DNA was extracted, PCR was performed for wild-type allele and Leiden mutation with GH internal control for both reactions, and agarose gel electrophoresis was performed. Of 100 samples, five were heterozygous for FVL, which is in accord with other reports. Interestingly, four of 70 samples (5.8%) from African-Americans were positive for the mutation. The study indicates an apparent prevalence of 5% in the Newark, New Jersey population, including African-Americans.
