Risk factors for pediatric intracranial neoplasms in the Kids' Inpatient Database (KID).

INTRODUCTION: In children and adolescents brain and central nervous system (CNS) tumors are the leading types of cancers. Past studies have found differing rates of intracranial cancers among races and identified additional cancer risk factors. This study aims to see if these differences can be substantiated with further investigation of the latest version (2019) of the Kids' Inpatient Database (KID). METHODS: A total of 7,818 pediatric patients <21 years old in KID with ICD-10 codes consisting of malignant neoplasms of the brain, brainstem, and cerebral meninges (C700, C709-C719) were queried. Modifiable risk factors evaluated include: hospital region, insurance type, hospital city size, the average income of patient zip code, and location/teaching status of a hospital. Non-modifiable risk factors were race and sex at birth. Dependent variables were tested in Excel and GraphPad Prism 9 using a Chi-squared test with Yates' continuity correction and Tukey's one-way and two-way ANOVAs. RESULTS: Mortality rates of females (2.88%) compared to males (1.99%) were significant (p<0.05). Mortality was (4.17%) in Black patients compared to (1.68%) for White (p<0.0001), Hispanic mortality (2.95%) compared to White (p<0.01), and mortality of Asian/Pacific Islander (3.86%) compared to White (p<0.01). Black patients had significantly higher mortality than White, Hispanic, Asian/Pacific Islander, Native American, and other races overall (p<0.01). There was no significant difference in the mortality rates between children's hospitals and large hospitals for any race. After accounting for patient race, mortality was still not significantly different for patients with Medicaid insurance compared to non-Medicaid insurance types. Of the children treated at children's hospitals, the most transferred in from outside hospitals were Native American (20.00%) followed by Asian/PI (15.09%) then Hispanic patients (13.67%). A significant difference between races was also seen regarding length of stay (p<0.001) and number of charges (p<0.001). CONCLUSION: These findings confirm prior studies suggesting gender and race are significant factors in mortality rates for children with intracranial neoplasms. However, the findings do not identify the root causes of these discrepancies but may serve as an impetus for clinicians, healthcare administrators, and governmental leaders to improve national resource allocation to better care for pediatric patients with intracranial neoplasms.

The prevalence and demographic associations of headache in the adult population of Peru: a national cross-sectional population-based study.

BACKGROUND: The Global Campaign against Headache is conducting a series of population-based studies to fill the large geographical gaps in knowledge of headache prevalence and attributable burden. One major region not until now included is South America. Here we present a study from Peru, a country of 32.4 million inhabitants located at the west coast of South America, notable for its high Andes mountains. METHODS: The study was conducted in accordance with the standardized methodology used by the Global Campaign. It was a cross-sectional survey using cluster randomised sampling in five regions to derive a nationally representative sample, visiting households unannounced, and interviewing one randomly selected adult member (aged 18-65 years) of each using the Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) questionnaire translated into South American Spanish. The neutral screening question ("Have you had headache in the last year?") was followed by diagnostic questions based on ICHD-3 and demographic enquiry. RESULTS: The study included 2,149 participants from 2,385 eligible households (participating proportion 90.1%): 1,065 males and 1,084 females, mean age 42.0 ± 13.7 years. The observed 1-year prevalence of all headache was 64.6% [95% CI: 62.5-66.6], with age-, gender- and habitation-adjusted prevalences of 22.8% [21.0-24.6] for migraine (definite + probable), 38.9% [36.8-41.0] for tension-type headache (TTH: also definite + probable), 1.2% [0.8-1.8] for probable medication-overuse headache (pMOH) and 2.7% [2.1-3.5] for other headache on ≥ 15 days/month (H15+). One-day prevalence of headache (reported headache yesterday) was 12.1%. Migraine was almost twice as prevalent among females (28.2%) as males (16.4%; aOR = 2.1; p < 0.001), and strongly associated with living at very high altitude (aOR = 2.5 for > 3,500 versus < 350 m). CONCLUSION: The Global Campaign's first population-based study in South America found headache disorders to be common in Peru, with prevalence estimates for both migraine and TTH substantially exceeding global estimates. H15 + was also common, but with fewer than one third of cases diagnosed as pMOH. The association between migraine and altitude was confirmed, and found to be strengthened at very high altitude. This association demands further study.

Elder abuse experienced by older Mexican women with disabilities: a current and retrospective view on domestic violence.

The objectives of this study were: 1) to estimate the prevalence of child abuse (CA), intimate partner violence (IPV), and elder abuse (EA) in a representative sample of older Mexican women by status, type, and cause of disability; and 2) to examine the associations of EA with CA, IPV, and disability status. We conducted a secondary data analysis of 21,718 women aged 60 years and older. Older women with disabilities had higher prevalences of CA, IPV, and EA than those with some difficulties or without disabilities. In older women whose disability was acquired at birth or due to aggression, this prevalence was especially high. Older women with disabilities and a history of CA and IPV were twice as likely to suffer EA. Policymakers and government leaders should incorporate the matter of violence against women with disabilities into their public agendas. This should be done while considering the women's various disabilities and causes of disability.

Temporal lobe interictal spikes disrupt encoding and retrieval of verbal memory: A subregion analysis.

OBJECTIVE: The medial temporal lobe (MTL) encodes and recalls memories and can be a predominant site for interictal spikes (IS) in patients with focal epilepsy. It is unclear whether memory deficits are due to IS in the MTL producing a transient decline. Here, we investigated whether IS in the MTL subregions and lateral temporal cortex impact episodic memory encoding and recall. METHODS: Seventy-eight participants undergoing presurgical evaluation for medically refractory focal epilepsy with depth electrodes placed in the temporal lobe participated in a verbal free recall task. IS were manually annotated during the pre-encoding, encoding, and recall epochs. We examined the effect of IS on word recall using mixed-effects logistic regression. RESULTS: IS in the left hippocampus (odds ratio [OR] = .73, 95% confidence interval [CI] = .63-.84, p < .001) and left middle temporal gyrus (OR = .46, 95% CI = .27-.78, p < .05) during word encoding decreased subsequent recall performance. Within the left hippocampus, this effect was specific for area CA1 (OR = .76, 95% CI = .66-.88, p < .01) and dentate gyrus (OR = .74, 95% CI = .62-.89, p < .05). IS in other MTL subregions or inferior and superior temporal gyrus and IS occurring during the prestimulus window did not affect word encoding (p > .05). IS during retrieval in right hippocampal (OR = .22, 95% CI = .08-.63, p = .01) and parahippocampal regions (OR = .24, 95% CI = .07-.8, p < .05) reduced the probability of recalling a word. SIGNIFICANCE: IS in medial and lateral temporal cortex contribute to transient memory decline during verbal episodic memory.

Cyclin-dependent kinase 4 expression alters the number of keratinocyte stem cells in the mouse hair follicle.

Hair follicles regenerate periodically by spontaneously undergoing cycles of growth, regression, and relative quiescence. During the hair cycle, follicle stem cells residing in a specialized niche remain quiescent, and they are stimulated to proliferate throughout the growth phase of the hair follicle. Although cell cycle regulators play a prominent role during the activation of hair follicle stem cells, the identity and the role of these regulators have not been confirmed. Herein, we reported that stem cells located in the bulge region of the HF (BuSCs) express high levels of cyclin-dependent kinase 4 (CDK4) through the quiescent phase of the hair cycle. Using gain- and loss-of-function studies, we have determined that the CDK4 protein level affects the number of BuSCs. Transgenic expression of CDK4 in the bulge region of the hair follicles reduces the number of BuSCs, whereas CDK4 ablation resulted in an increasing number of BuSCs. These results suggest that deregulation of CDK4 protein levels contributes to distorting the self-renewal/proliferation balance and, in turn, altering the number of BuSCs.

The revictimization of older Mexican women: understanding the accumulation of multiple victimizations throughout a lifetime.

BACKGROUND: The victimization of women constitutes a human rights violation and a health risk factor. The central objectives of this study were to analyze the probability of revictimization among older adult Mexican women and to examine whether child abuse (CA) and/or intimate partner violence (IPV) are associated with a greater risk of elder abuse (EA) victimization. METHODS: We conducted a secondary data analysis of 18416 women 60 and older, based on data from the National Survey on the Dynamics of Household Relationships (2016), which is national and subnational representative. A descriptive analysis was carried out using retrospective self-reports of victimization experiences (CA, IPV, and EA). The prevalence of victimization and multiple victimizations in the various stages of the lives of women, as well as of revictimization among older adult women were obtained. Bayesian logistic regression models were used to examine the associations between victimization, multiple victimization, and EA victimization. RESULTS: A total of 17.3% of the older adult women reported EA in the last year; of these, 81.0% had been revictimized and 14.0% reported CA, IPV, and EA. The risk of EA rose among women who reported a combination of psychological and sexual CA, and psychological, physical and sexual CA and psychological and sexual IPV, and a psychological, economic, physical and sexual IPV. EA was higher among women who had suffered more than one type of violence. CONCLUSION: CA and IPV, particularly sexual abuse and psychological violence, can be risk factors for EA. Screening tools used to prevent and detect EA should include questions about domestic violence over the course of a person's lifetime.

Type 2 diabetes and depressive symptoms in the adult population in Mexico: a syndemic approach based on National Health and Nutrition Survey.

BACKGROUND: The syndemic approach allows the analysis of clusters of diseases that affect a population in contexts of geographic, social and economic inequalities at the same moment and time. This study aims to analyze, from a syndemic perspective, the relationship between type 2 diabetes (T2D) and depressive symptoms in Mexican adults and its association with individual, contextual and structural factors. METHODS: Observational, cross-sectional study based on secondary data from Mexico's National Health and Nutrition Survey 2018-19. The sample of this study consisted of 16 835 adults, which represented a total of 78 463 734 persons aged ≥ 20 years. Bivariate descriptive analyses were performed and logistic regression models were estimated to analyze the association between T2D and depressive symptoms with various co-variables. In addition, interactions between T2D and depressive symptoms with obesity, educational level, and socioeconomic status were tested. RESULTS: In the study population, 12.2% of adults aged 20 years and older self-reported having T2D, 14.7% had depressive symptoms and 2.8% had both diseases. There was a statistically significant relationship between T2D and depressive symptoms. The prevalence of T2D and depressive symptoms was higher compared to people who did not have these two conditions. Obesity increased the probability of having T2D, while violence was statistically associated with people having depressive symptoms. A low level of education increased the odds ratio of having T2D and depressive symptoms. CONCLUSION: The availability of analytical frameworks such as the syndemic perspective could help to identify areas of opportunity for decision making and actions for population groups that-because of their individual, contextual and structural disadvantages-are at greater risk of experiencing poorer health outcomes due to the presence of T2D and depressive symptoms.

[Chronic degenerative conditions as risk factors for lethal COVID-19Doenças crônicas degenerativas como fator de risco para letalidade por COVID-19]. / Enfermedades crónicas degenerativas como factor de riesgo de letalidad por COVID-19 en México.

Objective: To determine the relative risk of a lethal outcome associated with chronic degenerative conditions in patients with COVID-19. Methods: A cohort study was conducted using electronic medical records belonging to patients who tested positive for COVID-19 on RT-PCR while receiving care as outpatients or inpatients in a social security system facility between March 2020 and March 2021. Two study groups were formed. The exposed group was divided into four subgroups, each of which was diagnosed with one and only one chronic condition (diabetes, hypertension, obesity, or chronic kidney disease); the unexposed group was obtained from the medical records of patients without comorbidities. A total of 1 114 medical records were examined using simple random sampling. Once the minimum sample size was reached, the relative risk was calculated for each chronic condition. Combinations of two, three, and four conditions were created, and each of them was included in the analysis. Results: In the absence of a chronic degenerative condition, the prevalence of a lethal outcome from COVID-19 is 3.8%; in the presence of type 2 diabetes mellitus, 15.8%; in the presence of arterial hypertension, 15.6%; and in the presence of obesity, 15.0%. For diabetes and hypertension combined, the prevalence of a lethal outcome is 54.1%; for diabetes and obesity combined, 36.8%, and for obesity and hypertension combined, 28.1%. Conclusion: In patients with COVID-19, the relative risk of a lethal outcome is 4.17 for those with diabetes, 4.13 for those with hypertension, and 3.96 for those with obesity. For two chronic conditions combined, the relative risk doubles or triples. The relative risk of a lethal outcome is 14.27 for diabetes plus hypertension; 9.73 for diabetes plus obesity, and 7.43 for obesity plus hypertension. Chronic conditions do not present alone; they generally occur together, hence the significance of the relative risks for lethal outcomes presented in this paper.

Objetivo: Determinar o risco de letalidade conferido por doenças crônicas degenerativas em pacientes com COVID-19. Métodos: Foi realizado um estudo de coorte em prontuários eletrônicos de pacientes com RT-PCR positivo para COVID-19 em atendimento ambulatorial ou hospitalar em uma instituição de previdência social, no período de março de 2020 a março de 2021. Foram constituídos dois grupos de estudo. O grupo exposto foi dividido em quatro subgrupos, cada um com diagnóstico único e exclusivo de uma doença crônica (diabetes, hipertensão, obesidade ou doença renal crônica). O grupo não exposto foi constituído por prontuários de pacientes sem comorbidades. Foram revisados 1.114 prontuários no total, utilizando técnica de amostragem aleatória simples. Uma vez obtido o tamanho mínimo da amostra, foi calculado o risco relativo para cada doença crônica. Foram realizadas combinações de 2, 3 e 4, tendo sido feita a análise com cada uma delas. Resultados: Na ausência de doença crônica degenerativa, a prevalência de letalidade na COVID-19 é de 3,8%; na presença de diabetes mellitus tipo 2, a letalidade é de 15,8%; na presença de hipertensão arterial, 15,6%; e na presença de obesidade, 15%. Quando tanto diabetes como hipertensão estão presentes, a letalidade é de 54,1%; com diabetes e obesidade, 36,8%; e obesidade com hipertensão, 28,1%. Conclusões: Em pacientes com COVID-19, o risco relativo de letalidade é de 4,17 naqueles com diabetes; 4,13 naqueles com hipertensão; e 3,96 naqueles com obesidade. Quando duas doenças crônicas são combinadas, o risco relativo dobra ou triplica. Para diabetes e hipertensão, o risco relativo de letalidade é 14,27; para diabetes e obesidade, 9,73; e para obesidade e hipertensão, 7,43. As doenças crônicas não ocorrem sozinhas (geralmente estão associadas), e nessa perspectiva os riscos relativos de letalidade apresentados neste artigo tornam-se relevantes.

Barriers to managing elder abuse in primary care services: experiences of healthcare providers in Mexico City.

The purpose of this study was to analyze the barriers to managing elder abuse from the perspective of primary care health workers in Mexico City. We performed an ethnographic qualitative-descriptive study. Thirty semi-structured interviews were conducted with healthcare providers associated with three health centers located in areas with medium and high levels of poverty. A phenomenological approach was used to identify themes, subthemes and codes. Three main types of barriers were found: 1) institutional framework; 2) professional competency limitations and the dominance of a biomedical vision; and 3) the invisibilization of elder abuse. These barriers, described by healthcare workers, highlight the complexity involved in integrating the treatment of elder abuse into primary care health services. It is necessary to develop public educational and preventive public policies for elder abuse that are coordinated both with support services to treat such cases as well as with programs to strengthen healthcare providers professional competency.

Contribution of left supramarginal and angular gyri to episodic memory encoding: An intracranial EEG study.

The role of the left ventral lateral parietal cortex (VPC) in episodic memory is hypothesized to include bottom-up attentional orienting to recalled items, according to the dual-attention model (Cabeza et al., 2008). However, its role in memory encoding could be further clarified, with studies showing both positive and negative subsequent memory effects (SMEs). Furthermore, few studies have compared the relative contributions of sub-regions in this functionally heterogeneous area, specifically the anterior VPC (supramarginal gyrus/BA40) and the posterior VPC (angular gyrus/BA39), on a within-subject basis. To elucidate the role of the VPC in episodic encoding, we compared SMEs in the intracranial EEG across multiple frequency bands in the supramarginal gyrus (SmG) and angular gyrus (AnG), as twenty-four epilepsy patients with indwelling electrodes performed a free recall task. We found a significant SME of decreased theta power and increased high gamma power in the VPC overall, and specifically in the SmG. Furthermore, SmG exhibited significantly greater spectral tilt SME from 0.5 to 1.6 s post-stimulus, in which power spectra slope differences between recalled and unrecalled words were greater than in the AnG (p = 0.04). These results affirm the contribution of VPC to episodic memory encoding, and suggest an anterior-posterior dissociation within VPC with respect to its electrophysiological underpinnings.

Comparison between Covid-19 and influenza A(H1N1) pandemic experiences and risk perception in Mexican university.

OBJECTIVE: To compare the perceptions and experiences between the A(H1N1) and Covid-19 pandemics in a univer-sity population. MATERIALS AND METHODS: Online surveys were administered during the influenza A(H1N1) -originated in Mexico in 2009- and Covid-19 epidemics. MEASURES: so-ciodemographic characteristics, knowledge, information and communication, perception of risk, physical and mental health, effects on daily life, and preventive behaviors. RESULTS: This study included 24 998 respondents, 51.36% from the A(H1N1) group and 48.63% from the Covid-19 group. Differences were observed in the perception of severity. During the influenza A(H1N1) pandemic worry was the feeling reported most frequently, while for Covid-19 it was anxiety. Covid-19 had greater impact on students' family economy and caused a higher uncertainty. CONCLUSIONS: The perceptions and ex-periences of the two pandemics were similar but the impact has been much greater for Covid-19, especially in terms of the severity, family economy, preventive behaviors, and uncertainty.

Intrinsic and extrinsic factors associated with falls in older adults: a case-control study in Mexico.

BACKGROUND: The literature refers that falls are of multifactorial origin, and some authors have proposed to classify risk factors as intrinsic and extrinsic. OBJECTIVE: To estimate the risk of falls and their association with some intrinsic and extrinsic factors in older adults who receive medical care at the Mexican Institute of Social Security. METHODS: Case-control study that included individuals of both genders aged ≥ 60 years. Cases were patients who were admitted to the emergency department of a secondary care hospital diagnosed with injury or fracture secondary to a fall; the controls were patients who attended family medicine units. Descriptive, bivariate and multivariate statistical analysis was carried out. The SPSS program, version 22.0, was used. RESULTS: Three-hundred and forty-two patients were included (171 cases and 171 controls). Mean age was 76.1 ± 8.8 years, 66 % were women and 97.1 % had self-reported chronic diseases. Differences were observed in body mass index, in the proportion of cases with cognitive impairment, use of walking devices and dependence to perform basic and instrumental activities of daily living. Adjusted multivariate analysis revealed an association between the fall event and cognitive impairment and dependence to perform instrumental activities of daily living. CONCLUSIONS: Cognitive impairment and dependence to perform instrumental activities of daily living were associated with the risk of falling.

ANTECEDENTES: Las caídas tienen un origen multifactorial. OBJETIVO: Estimar el riesgo de caídas y su asociación con algunos factores intrínsecos y extrínsecos en adultos mayores. MÉTODOS: Estudio de casos y controles que incluyó pacientes de ambos sexos con edades ≥ 60 años. Los casos fueron pacientes que ingresaron al servicio de urgencias de un hospital de segundo nivel, con diagnóstico de lesión o fractura secundaria a una caída; los controles fueron pacientes que acudieron a unidades de medicina familiar. El análisis estadístico que se realizó fue descriptivo, bivariante y multivariante. Se utilizó el programa SPSS versión 22.0. RESULTADOS: Se incluyeron 342 pacientes (171 casos y 171 controles). La edad promedio fue 76.1 ± 8.8 años, el 66 % fueron mujeres y por autorreporte el 97.1 % tenían enfermedades crónicas. Se observaron diferencias en el índice de masa corporal, en la proporción de casos con deterioro cognitivo, uso de dispositivos para caminar y dependencia para realizar actividades básicas e instrumentales de la vida diaria. El análisis multivariante ajustado reveló asociación entre el evento caída con deterioro cognitivo y dependencia para realizar actividades instrumentales de la vida diaria. CONCLUSIONES: El deterioro cognitivo y la dependencia para realizar actividades instrumentales de la vida diaria se asociaron al riesgo de caer.

Health care trajectories and barriers to treatment for patients with end-stage renal disease without health insurance in Mexico: a mixed methods approach.

BACKGROUND: Mexico has the sixth-highest premature death rate from chronic kidney disease (CKD) in the world. From 1990 to 2017, the age-standardized CKD mortality rate jumped from 28.7 to 58.1 per 100,000 inhabitants, making it the second-leading cause of death that year. Medical care for the disease is inequitable, as those without health insurance have limited access to renal replacement therapy (RRT). The objective of this study is to describe the healthcare trajectories of patients with end-stage renal disease (ESRD) in a public hospital in Mexico City and the barriers they face in receiving peritoneal dialysis and haemodialysis. METHODS: This study uses a convergent mixed methods approach and is predominantly qualitative. Patients completed 199 surveys, and 42 semi-structured interviews with patients having ESRD and their families were conducted. The quantitative data were analysed using descriptive statistics, and the qualitative data were processed using a phenomenological approach. RESULTS: It was found that 76.9% of the patients received peritoneal dialysis or haemodialysis as their first RRT. Over 30% began their treatment at least a month after a health professional prescribed it. Almost 50% had been hospitalized for complications related to the disease in the previous year, and 36% had uncertainties about their treatment. Close to 64% of the haemodialysis patients received treatment intermittently. Barriers to accessing treatment, information, contact with health services, and treatment availability were identified. Patients and their families encountered economic and emotional difficulties at every phase of their search for medical care and treatment. CONCLUSION: Mexico urgently needs to implement public policies related to CKD that are primarily directed at its prevention but should also implement policies directed at slowing its progression, reducing its complications, and providing funding for uninsured patients who require RRT. These policies must be based on the perspectives of human rights and equality, and the perspectives of patients, their families and the general population should be included in the policy creation process.

Acceptability and feasibility of using digital vending machines to deliver HIV self-tests to men who have sex with men.

OBJECTIVE: Technology-based approaches to distribute HIV self-tests (HIVST) have the potential to increase access to HIV testing in key populations. We evaluate the acceptability and feasibility of using vending machines (VMs) in a community setting to distribute HIVST to men who have sex with men at high-risk of HIV. METHODS: First, a predevelopment survey of targeted potential users explored attitudes towards HIVST and the use of a VM to deliver HIVST. Second, participatory design workshops between designers and community volunteers informed the production of a bespoke VMs dispensing free BioSureHIVST. Uptake of HIVST and user experiences were evaluated using information supplied directly from the machines interface (number of tests dispensed, user demographics), an online questionnaire and semistructured interviews. RESULTS: The predevelopment survey found that 32% of 232 sauna users had never tested for HIV, despite high-risk behaviours. A total of 265 testing kits were dispensed: mean age 31 range (18-70); 4%(n = 7) had never tested for HIV before and 11% (n = 22) had tested within the last 1-5 years. Uptake of tests was significantly higher via the VMs compared with outreach testing by community workers in the same venue during a comparable period (34 vs 6 tests per month). Qualitative interviews and online questionnaires demonstrated high acceptability for this intervention, which was considered accessible and appropriately targeted. CONCLUSIONS: VMs to distribute HIVST was feasible and acceptable. This intervention could be used in different settings to improve access to HIV testing for key populations.

Epidemiology, progression, and predictive factors of urinary incontinence in older community-dwelling Mexican adults: Longitudinal data from the Mexican Health and Aging Study.

AIMS: To understand the epidemiology, progression, and predictive factors of urinary incontinence (UI) in community-dwelling Mexican adults aged ≥ 50 by sex and UI subtypes (stress, urge, and mixed). METHODS: We analyzed longitudinal UI data in community-dwelling adults aged ≥ 50 (7783 women and 5843 men) for the 2012 to 2015 period of the Mexican Health and Aging Study. We estimated mixed, stress, and urgency incontinence prevalence (2012); 2-year cumulative incidence and remissions (2015); and progression (2012-2015). A multivariate analysis was undertaken to evaluate the predictive factors for UI and its subtypes by sex. RESULTS: The prevalence of UI was higher (27.7%) for women (average age 65.9 ± 9.5) than 12.5% men (average age 67.4 ± 9.3) and increased with age in both sexes (26.7% in women 50 to 59, to 48.5% in ≥ 90; and 6.8% in men 50 to 59, to 26.2% ≥ 90). The most frequent UI subtypes were mixed in women and urge in men. The cumulative incidence of UI was higher in women (22.9%) than men (12.3%) while its remission was higher in men than women. Predictive factors for UI in both sexes were depressive symptoms, a higher number of concomitant diseases and a history of falls; while advanced age was a factor only for men. CONCLUSIONS: UI is a common health problem and its prevalence and severity increase with age. Addressing modifiable risk factors such as depression and falls could decrease the prevalence and incidence of UI and its subtypes. Further studies should also focus on the relationship between mixed UI and male mortality.

Psychiatric Aspects of Acute Porphyria: a Comprehensive Review.

PURPOSE OF REVIEW: The aim of this paper is to review psychiatric manifestations, comorbidities, and psychopharmacological management in individuals with acute porphyria (AP). RECENT FINDINGS: Recent literature begins to clarify associations between AP, schizophrenia, bipolar disorder, and other psychopathology. Broad psychiatric symptoms have been associated to acute porphyria (AP) and correspond to a spectrum of heterogeneous manifestations such as anxiety, affective alterations, behavioral changes, personality, and psychotic symptoms. These symptoms may be difficult to identify as being related to porphyria since symptoms may arise at any time during the disease process. In addition, these patients may present psychiatric conditions secondary to the disease, such as adjustment disorder and substance use disorders. Timely diagnosis and appropriate treatment of psychiatric manifestations positively impact the course of the disease.

Mind-Body Therapies in Childhood Cancer.

PURPOSE OF REVIEW: Advances in the field of Pediatric Oncology have led to increased survival rates in children with cancer, and addressing the emotional well-being and quality of life of this specific population is a critical component of care. Mind-body therapies (MBTs) are an adjuvant modality of treatment that appears to have a positive impact on patient quality of life, patient mental health, and family perceptions toward illness. In this review, we describe several evidence-based MBTs, such as art therapy, meditation, prayer, music therapy, hypnosis and relaxation techniques, their use, and our personal experience with MBT in our institution. RECENT FINDINGS: Current data suggests that MBTs have been effective in decreasing symptoms related to oncologic pathology in children. Based on experience in our institution, the administration of these therapies can be expanded with the use of technology and also foster family inclusion in care, which can lead to improved quality of life for the patient and family. Further studies are warranted to ascertain the effects of MBTs in childhood cancer. MBTs are increasingly important in the care of youth with oncologic disease. It is necessary to increase the quantity and quality of research for the selection and inclusion of MBT in this population.

Ripple oscillations in the left temporal neocortex are associated with impaired verbal episodic memory encoding.

BACKGROUND: We sought to determine if ripple oscillations (80-120 Hz), detected in intracranial electroencephalogram (iEEG) recordings of patients with epilepsy, correlate with an enhancement or disruption of verbal episodic memory encoding. METHODS: We defined ripple and spike events in depth iEEG recordings during list learning in 107 patients with focal epilepsy. We used logistic regression models (LRMs) to investigate the relationship between the occurrence of ripple and spike events during word presentation and the odds of successful word recall following a distractor epoch and included the seizure onset zone (SOZ) as a covariate in the LRMs. RESULTS: We detected events during 58,312 word presentation trials from 7630 unique electrode sites. The probability of ripple on spike (RonS) events was increased in the SOZ (p < 0.04). In the left temporal neocortex, RonS events during word presentation corresponded with a decrease in the odds ratio (OR) of successful recall, however, this effect only met significance in the SOZ (OR of word recall: 0.71, 95% confidence interval (CI): 0.59-0.85, n = 158 events, adaptive Hochberg, p < 0.01). Ripple on oscillation (RonO) events that occurred in the left temporal neocortex non-SOZ also correlated with decreased odds of successful recall (OR: 0.52, 95% CI: 0.34-0.80, n = 140, adaptive Hochberg, p < 0.01). Spikes and RonS that occurred during word presentation in the left middle temporal gyrus (MTG) correlated with the most significant decrease in the odds of successful recall, irrespective of the location of the SOZ (adaptive Hochberg, p < 0.01). CONCLUSION: Ripples and spikes generated in the left temporal neocortex are associated with impaired verbal episodic memory encoding. Although physiological and pathological ripple oscillations were not distinguished during cognitive tasks, our results show an association of undifferentiated ripples with impaired encoding. The effect was sometimes specific to regions outside the SOZ, suggesting that widespread effects of epilepsy outside the SOZ may contribute to cognitive impairment.

Antioxidant status in a group of institutionalised elderly people with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is one of the most important and prevalent diseases suffered by the elderly. Evidence exists that its onset and severity might be conditioned by antioxidant status. The aim of the present study was to investigate the relationship between antioxidant status and COPD in institutionalised elderly people. In all, 183 elderly people aged >65 years (twenty-one had COPD and 160 healthy controls) were studied. The subjects' diets were investigated via the use of precise individual weighing for 7 d. Body weight, height, and biceps and triceps skinfold thickness were measured, and body fat (kg) and BMI (kg/m2) were calculated. Serum retinol, α-tocopherol, ß-carotene and vitamin C levels were determined. Subjects with COPD ate less fruits than healthy controls (117 (sd 52) v. 192 (sd 161) g/d), their coverage of the recommended intake of vitamin C was smaller (150 (sd 45) v. 191 (sd 88) %; note that both exceeded 100 %) and their diets had a lower antioxidant capacity (6558 (sd 2381) v. 9328 (sd 5367) mmol trolox equivalent/d). Those with COPD had lower serum vitamin C and α-tocopherol concentrations than healthy controls (32·4 (sd 15·3) v. 41·5 (sd 14·8) µmol/l and 12·1 (sd 3·2) v. 13·9 (sd 2·8) µmol/l, respectively). In addition, subjects with α-tocopherol <14·1µmol/l (50th percentile) were at 6·43 times greater risk of having COPD than those subjects with ≥14·1µmol/l (OR 6·43; 95 % CI 1·17, 35·24; P<0·05), taking sex, age, use of tobacco, body fat and vitamin E intake as covariables. Subjects with COPD had diets of poorer antioxidant quality, especially with respect to vitamins C and E, compared with healthy controls.

Relationship between 24 h urinary potassium and diet quality in the adult Spanish population.

OBJECTIVE: To study the relationship between diet quality and 24 h urinary K excretion. DESIGN: K was measured in 24 h urine samples, while diet was studied using a 24 h recall method over two consecutive days. Diet quality was determined using the Healthy Eating Index (HEI). The body weight, height and body composition of all participants were recorded, and the BMI of each calculated. SETTING: Representative members of the adult Spanish population from the FANPE Study ('Fuentes Alimentarias de Nutrientes en Población Española'; Dietary Sources of Nutrients in the Spanish Population). SUBJECTS: The final sample size was 329 participants aged 18-60 years. RESULTS: Participants with a 24 h urinary K excretion ≥ 93 mmol/d (group AP = adequate potassium) had greater self-reported K intakes, consumed more fruit and vegetables, had a more varied diet and had better HEI scores than those with a 24 h urinary K excretion <93 mmol/d (group IP = inadequate potassium). A significant positive correlation was seen between 24 h urinary K and dietary variety and the number of servings of fruits, vegetables and dairy products consumed, and between each of these and the HEI after correcting for age, sex, BMI, coefficient of activity, energy intake and the under-reporting of energy intake. AP participants were less likely to have an inadequate diet (HEI score <50) than IP participants (OR =0.439; 95 % CI 0.201, 0.961; P=0.039). CONCLUSIONS: Diet quality, measured by the HEI, is correlated with 24 h urinary K excretion in Spanish adults.
