The relation between cognitive functioning and activities of daily living in normal aging, mild cognitive impairment, and dementia: a meta-analysis.

Literature suggests that dementia and, more generally, cognitive impairment affect the capacity to carry out activities of daily living (ADL) in aging. However, it is important to decipher the weight of specific cognitive domains and neurodegenerative profiles mainly related to ADL difficulties. A meta-analysis was conducted to investigate the nature and strength of the association between cognitive functioning and ADL in healthy older adults, mild cognitive impairment (MCI), and dementia. A comprehensive search of the PubMed, PsycINFO (PROQUEST), and Scopus databases for cross-sectional or longitudinal studies up until December 2022. Our meta-analytic results revealed that: overall, instrumental ADL (IADL) showed a significant association with executive functioning, in particular, abstraction ability/concept formation, set-shifting, and processing speed/complex attention/working memory, regardless of type of participants (i.e., healthy older adults, MCI, and dementia); whereas ADL (both basic ADL, BADL, and IADL) significantly correlated with global cognitive functioning and long-term verbal memory, with a moderator effect of clinical condition (e.g., increasing ES based on the level of cognitive impairment). Moreover, visuospatial and language abilities significantly correlated with ADL, mainly when performance-based tasks were used for ADL assessment. These findings emphasize the importance of neuropsychological assessment in aging to early identify people most at risk of functional decline and shed light on the need to consider specific cognitive abilities in rehabilitation programs.

Evaluation of the Biological Activities of Peptides from Epidermal Mucus of Marine Fish Species from Chilean Aquaculture.

The skin of fish is a physicochemical barrier that is characterized by being formed by cells that secrete molecules responsible for the first defense against pathogenic organisms. In this study, the biological activity of peptides from mucus of Seriola lalandi and Seriolella violacea were identified and characterized. To this purpose, peptide extraction was carried out from epidermal mucus samples of juveniles of both species, using chromatographic strategies for purification. Then, the peptide extracts were characterized to obtain the amino acid sequence by mass spectrometry. Using bioinformatics tools for predicting antimicrobial and antioxidant activity, 12 peptides were selected that were chemically produced by simultaneous synthesis using the Fmoc-Tbu strategy. The results revealed that the synthetic peptides presented a random coil or extended secondary structure. The analysis of antimicrobial activity allowed it to be discriminated that four peptides, named by their synthesis code 5065, 5069, 5070, and 5076, had the ability to inhibit the growth of Vibrio anguillarum and affected the copepodite stage of C. rogercresseyi. On the other hand, peptides 5066, 5067, 5070, and 5077 had the highest antioxidant capacity. Finally, peptides 5067, 5069, 5070, and 5076 were the most effective for inducing respiratory burst in fish leukocytes. The analysis of association between composition and biological function revealed that the antimicrobial activity depended on the presence of basic and aromatic amino acids, while the presence of cysteine residues increased the antioxidant activity of the peptides. Additionally, it was observed that those peptides that presented the highest antimicrobial capacity were those that also stimulated respiratory burst in leukocytes. This is the first work that demonstrates the presence of functional peptides in the epidermal mucus of Chilean marine fish, which provide different biological properties when the fish face opportunistic pathogens.

Sagittal Growth Restriction of the Midface Following Isolated Cleft Lip Repair: A Systematic Review and Meta-Analysis.

Midface hypoplasia (MFH) is a long-term sequela of cleft lip and palate repair, and is poorly understood. No study has examined the aggregate data on sagittal growth restriction of the midface following repair of the lip, but not palate, in these patients.A systematic review of 3780 articles was performed. Twenty-four studies met inclusion criteria and 11 reported cephalometric measurements amenable to meta-analysis. Patients with Veau class I-III palatal clefts were included so long as they had undergone only lip repair. Groups were compared against both noncleft and unrepaired controls.Cephalometrics were reported for 326 patients (31.3% female). Noncleft controls had an average SNA angle of 81.25° ± 3.12°. The only patients demonstrating hypoplastic SNA angles were those with unilateral CLP with isolated lip repair (77.4° ± 4.22°). Patients with repaired CL had SNA angles similar to noncleft controls (81.4° ± 4.02°). Patients with unrepaired CLP and CL tended toward more protruding maxillae, with SNA angles of 83.3° ± 4.04° and 87.9° ± 3.11°, respectively. Notably, when comparing SNA angles between groups, patients with CLP with isolated lip repair had significantly more hypoplastic angles compared to those with repaired CL (P < .0001). Patients with CLP with isolated lip repair were also more hypoplastic than noncleft controls (P < .0001). In contrast, there was no significant difference between the SNA of patients with repaired CL and controls (P = .648).We found that cleft lip repair only appeared to contribute to MFH in the setting of concurrent cleft palate pathology, suggesting that scarring from lip repair itself is unlikely to be the predominant driver of MFH development. However, studies generally suffered from inadequate reporting of timing, technique, follow-up time, and cleft severity.

Hypothalamic miR-30 regulates puberty onset via repression of the puberty-suppressing factor, Mkrn3.

Mkrn3, the maternally imprinted gene encoding the makorin RING-finger protein-3, has recently emerged as putative pubertal repressor, as evidenced by central precocity caused by MKRN3 mutations in humans; yet, the molecular underpinnings of this key regulatory action remain largely unexplored. We report herein that the microRNA, miR-30, with three binding sites in a highly conserved region of its 3' UTR, operates as repressor of Mkrn3 to control pubertal onset. Hypothalamic miR-30b expression increased, while Mkrn3 mRNA and protein content decreased, during rat postnatal maturation. Neonatal estrogen exposure, causing pubertal alterations, enhanced hypothalamic Mkrn3 and suppressed miR-30b expression in female rats. Functional in vitro analyses demonstrated a strong repressive action of miR-30b on Mkrn3 3' UTR. Moreover, central infusion during the juvenile period of target site blockers, tailored to prevent miR-30 binding to Mkrn3 3' UTR, reversed the prepubertal down-regulation of hypothalamic Mkrn3 protein and delayed female puberty. Collectively, our data unveil a novel hypothalamic miRNA pathway, involving miR-30, with a prominent role in the control of puberty via Mkrn3 repression. These findings expand our current understanding of the molecular basis of puberty and its disease states.

Development of a family-based preventive intervention for Latinx sexual minority youth and their parents.

OBJECTIVE: Latinx sexual minority youth (LSMY) are disproportionately affected by adverse health outcomes, due to stigma and/or lack of family support. There are currently no family-based interventions for LSMY. This qualitative study describes the development of Familias con Orgullo (Families with Pride), a family-based intervention to prevent/reduce substance use, risky sexual behavior, and depressive symptoms in LSMY. METHOD: Familias con Orgullo was developed using an iterative, user-centered methodology across two study phases. A general inductive approach was used to analyze intervention development individual interviews (N = 24: n = 12 parents, n = 12 LSMY) and post-intervention focus groups (N = 4) to query participants about program components and enhancements to the developed program after delivery. Data were coded into 11 themes representative of program features for LSMY and their families. RESULTS: An intervention would need LSMY information delivered in a safe space and focused on communication, peer pressure, and mental health. Furthermore, participation would be dependent on parental level of acceptance. Informed by participants, we developed an intervention which addresses the multiple ecological levels of LSMY contexts within a cultural lens. Families gave positive feedback and indicated that additional content should focus on sexual health and intrapersonal topics. The intervention was modified and delivered to a new cohort of families; families felt the new intervention promoted inclusiveness; enriched relationships and communication between families; and enhanced lesbian, gay, bisexual, transgender, or queer (LGBTQ) knowledge. CONCLUSION: Familias con Orgullo begins to address the significant gap in intervention research with LSMY and their families. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Psychosocial impact of the COVID-19 pandemic on patients with inflammatory bowel disease in Spain. A post lockdown reflection.

OBJECTIVES: This multicenter cross-sectional study was conducted to assess the psychosocial impact of COVID-19 on patients with inflammatory bowel disease (IBD) in Spain during lockdown and the first wave of the pandemic. PATIENTS AND METHODS: A self-report questionnaire that integrated the Spanish version of the Depression, Anxiety and Stress Scale-21 items (DASS-21) and the Perceived Stress Questionnaire (PSS) was designed to gather sociodemographic data and information related to the effects of lockdown on the lives of IBD patients. Twelve IBD units invited their patients to answer the anonymous online survey between the 1st July and the 25th August 2020. RESULTS: Of the 693 survey participants with IBD, 67% were women and the mean age was 43 (SD 12). Sixty-one percent had ulcerative colitis, 36% Crohn's disease and 3% indeterminate colitis. DASS-21 scores indicate that during lockdown the estimated prevalence of depression was 11% [95% CI 8.2-13%], anxiety 20% [95% CI 17 to 23%] and stress 18% [95% CI 8.2-13%]. Multivariate analysis showed that the perceived high risk of COVID-19 infection because of having IBD and maladaptation to government measures to reduce the spread of disease doubled the risk of anxiety and stress during lockdown. CONCLUSIONS: In the short-term, lockdown during the COVID-19 pandemic seemed to have an impact on the already affected mental health of our IBD patients in Spain.

Do the heel-rise test and isometric strength improve after Achilles tendon repair using Dresden technique?

BACKGROUND: Achilles' tendon ruptures result in impaired plantar flexion strength and endurance. It is interesting to know the plantar flexion strength, the number of heel-rise repetitions, and the maximal calf circumference following Achilles' tendon ruptures repair. METHODS: Both the injured and non-injured legs of thirty male patients with Achilles' tendon ruptures treated with the percutaneous Dresden technique were compared with the ankle function of 30 healthy participants. Rehabilitation involved partial weight-bearing for three weeks and then increased to full weight-bearing and ankle exercises. RESULTS: The injured legs had weaker plantar flexion strength (1.64 ± 0.17 Nm/kg) compared with the non-injured legs (1.91 ± 0.24 Nm/kg; p = 0.002) and the healthy participants' legs (1.93 ± 0.32 Nm/kg; p < 0.001). The non-injured leg had greater ability in doing heel-rise repetitions (39.4 ± 6.1 rep.) compared with the injured legs (37.2 ± 5.7 rep.; p < 0.023) and the healthy participants' legs (31.0 ± 13.0 rep.; p < 0.001). CONCLUSIONS: The injured leg had not recovered full isometric strength but had improved heel-rise repetition.

Prospective study of diagnostic accuracy in the detection of high-grade prostate cancer in biopsy-naïve patients with clinical suspicion of prostate cancer who underwent the Select MDx test.

OBJECTIVES: This study aimed to externally validate the diagnostic accuracy of the Select MDx test for Significant prostate cancer (Sig PCa) (ISUP > 1), in a contemporaneous, prospective, multicenter cohort with a prostate-specific antigen (PSA) between 3 and 10 ng/ml and a non-suspicious digital rectal examination. METHODS AND PARTICIPANTS: For all enrolled patients, the Select Mdx test, the risk calculator ERSPC3 + DRE, and a prostatic magnetic resonance imaging (MRI) were carried out. Subsequently, a systematic 12-core trans-rectal biopsy and a targeted biopsy, in the case of a prostate imaging-reporting and data system (PIRADS) > 2 lesion (max three lesions), were performed. To assess the accuracy of the Select MDx test in the detection of clinically Sig PCa, the test sensitivity was evaluated. Secondary objectives were specificity, negative predictive value (NPV), positive predictive value (PPV), and area under the curve (AUC). A direct comparison with the ERSPC + DRE risk calculator and MRI were also performed. We also studied the predictive ability to diagnose Sig PCa from the combination of the Select MDx test with MRI using clinical decision-curve analysis. RESULTS: There were 163 patients enrolled after meeting the inclusion criteria and study protocol. The Select MDx test showed a sensitivity of 76.9% (95% CI, 63.2-87.5), 49.6% specificity (95% CI, 39.9-59.2), 82.09% (95% CI, 70.8-90.4) NPV, and 41.67% (95% CI, 31.7-52.2) PPV for the diagnosis of Sig PCa. COR analysis was also performed, which showed an AUC of 0.63 (95% CI, 0.56-0.71). There were no differences in the accuracy of Select MDx, ERSPC + DRE, or MRI. The combination of Select MDX + MRI showed the highest impact in the decision-curve analysis, with an NPV of 93%. CONCLUSION: Our study showed a worse performance for the SelectMdx test than previously reported, within a cohort of patients with a PSA 3-10 ng/ml and a normal DRE, with results similar to those from ERSPC + DRE RC and MRI, but with an improvement in the usual PSA pathway. A combination of the Select Mdx test and MRI could improve accuracy, but studies specifically evaluating this scenario with a cost-effective analysis are needed.

Zearalenone Adsorbent Based on a Lyophilized Indigenous Bacterial Lactobacillus plantarum Strain as Feed Additive for Pigs: A Preliminary Study In Vivo.

Feed contamination with naturally occurring mycotoxins is an unavoidable condition of significant concern in intensive productions. The presence of high concentrations of zearalenone >1 ppm in the diet can cause major reproductive disorders, particularly in swine. In order to reduce the consequences of intoxication, mycotoxin adsorbents are incorporated into feed. In the present study, zearalenone adsorption capacity of a lyophilized indigenous strain of Lactobacillus plantarum (L4; previously isolated from pig's rectal swabs) was first evaluated in vitro. A preliminary study in vivo was then performed in which the indigenous Lactobacillus plantarum strain was lyophilized and the powder obtained (L-L4) was incorporated into the diet of gilts two gilts received basal diet (control) and two received basal diet containing 2 g/kg L-L4 (treated). After an adaptation period, all the feed was contaminated with zearalenone at a dose of 0.93 mg ZEA/kg. Results from in vitro assay showed that L-L4 adsorbed 87.9% (SD 3.97) of zearalenone in 0.9% NaCl solution. In the in vivo exploratory study, higher daily weight gain and lower vulva area were observed in gilts that incorporated L-L4 to the diet. Additionally, higher zearalenone concentrations were eliminated in faeces from treated animals. The use of a product based on a lyophilized indigenous Lactobacillus strain to protect gilts from detrimental effects of zearalenone consumption has shown promising results so far. However, further studies are required in order to accurately assess its impact and evaluate doses according to different degrees of mycotoxins contamination.

Understanding the Lived Experiences of Hispanic Sexual Minority Youth and their Parents.

Disclosure of sexual identity and/or gender orientation is difficult for youth and is associated with elevated adverse health risks, particularly when there is parental rejection. There are limited studies conducted with Hispanic sexual minority youth (HSMY) and their families to understand the disclosure process, how the family unit changes and adapts following disclosure, and the implications for preventive interventions for HSMY and their families. This paper explores the lived experiences of youth and parents throughout the disclosure process. A phenomenological approach was used to interview 15 parent-youth dyads (N = 30) to understand what it means for Hispanic youth to disclose their sexual identity and/or gender orientation. Three themes that best described the experience emerged from the participant interviews; the experience of disclosing included intrapersonal challenges, navigating disclosure, and conceptualizing acceptance. The authors highlight implications for preventive interventions that can help these families undergoing the unique process of disclosure.

La revelación de la identidad sexual o la orientación de género es difícil para los jóvenes y está asociada con riesgos adversos elevados para la salud, particularmente cuando existe rechazo por parte de los padres. Se han realizado pocos estudios con jóvenes de minorías sexuales hispanas y sus familias para comprender el proceso de revelación, cómo el núcleo familiar cambia y se adapta después de la revelación, y las consecuencias para las intervenciones preventivas orientadas a los jóvenes de minorías sexuales hispanas y sus familias. En este artículo se analizan las experiencias vividas de los jóvenes y sus padres a lo largo del proceso de revelación. Se utilizó un método fenomenológico para entrevistar a 15 díadas de padres y jóvenes (N = 30) a fin de comprender qué significa para los jóvenes hispanos revelar su identidad sexual o su orientación de género. De las entrevistas a los participantes surgieron tres temas que describieron mejor la experiencia; la experiencia de la revelación incluyó desafíos intrapersonales, el paso por la revelación y la conceptualización de la aceptación. Los autores destacan las implicancias para las intervenciones preventivas que pueden ayudar a estas familias a atravesar el proceso único de la revelación.

A Feasibility Trial of an Online-Only, Family-Centered Preventive Intervention for Hispanics: e-Familias Unidas.

We piloted the preventive intervention e-Familias Unidas, delivered exclusively through the Internet to maximize reach and sustainability. This program is an adaptation of an evidence-based, family-centered intervention that aims to prevent Hispanic adolescent drug use and risky sexual behavior through improving family functioning. The purpose of this feasibility trial was to: (1) explore the use of Facebook and a trusted community champion in the online recruitment of Hispanic parents of adolescents, (2) test an online-only assessment and randomization protocol, (3) pilot intervention delivery via e-familiasunidas.com, and (4) assess pre-post changes in family functioning. We tracked participant recruitment and enrollment via Facebook analytics and REDCap. Intervention completion was tracked via our website. We conducted an ANCOVA to test for between group (e-Familias Unidas vs. control) differences post-intervention. Recruitment lasted for a total of 10 weeks and was divided into three phases, with each phase systematically assessing which strategies maximized recruitment and enrollment. Overall, 93 Hispanic parents enrolled in the study. Of those randomized to the intervention group (n = 46), 70% were engaged and watched an average of 5.4 out of the 12 online videos. We found that participants recruited through a community champion, versus Facebook advertisements, had higher rates of enrollment and intervention completion. There was a significant improvement in parent-adolescent communication for parents who received e-Familias Unidas compared to those in the control group (n = 47). This pilot trial demonstrated it is feasible to recruit, assess, and deliver e-Familias Unidas to Hispanic parents through an online-only platform. Our findings highlight the promise of an online platform to optimize the reach of preventive interventions for underserved populations, to more effectively target participants, and to disseminate sustainable evidence-based interventions. We discuss lessons learned and recommendations for future research.

The Latin American network for congenital malformation surveillance: ReLAMC.

The early detection of congenital anomaly epidemics occurs when comparing current with previous frequencies in the same population. The success of epidemiologic surveillance depends on numerous factors, including the accuracy of the rates available in the base period, wide population coverage, and short periodicity of analysis. This study aims to describe the Latin American network of congenital malformation surveillance: ReLAMC, created to increase epidemiologic surveillance in Latin America. We describe the main steps, tasks, strategies used, and preliminary results. From 2017 to 2019, five national registries (Argentina [RENAC], Brazil [SINASC/SIM-BRS], Chile [RENACH], Costa Rica [CREC], Paraguay [RENADECOPY-PNPDC]), six regional registries (Bogotá [PVSDC-Bogota], Cali [PVSDC-Cali], Maule [RRMC SSM], Nicaragua [SVDC], Nuevo-León [ReDeCon HU], São Paulo [SINASC/SIM-MSP]) and the ECLAMC hospital network sent data to ReLAMC on a total population of 9,152,674 births, with a total of 101,749 malformed newborns (1.1%; 95% CI 1.10-1.12). Of the 9,000,651 births in countries covering both live and stillbirths, 88,881 were stillborn (0.99%; 95% CI 0.98-0.99), and among stillborns, 6,755 were malformed (7.61%; 95% CI 7.44-7.79). The microcephaly rate was 2.45 per 10,000 births (95% CI 2.35-2.55), hydrocephaly 3.03 (2.92-3.14), spina bifida 2.89 (2.78-3.00), congenital heart defects 15.53 (15.27-15.79), cleft lip 2.02 (1.93-2.11), cleft palate and lip 2.77 (2.66-2.88), talipes 2.56 (2.46-2.67), conjoined twins 0.16 (0.14-0.19), and Down syndrome 5.33 (5.18-5.48). Each congenital anomaly showed heterogeneity in prevalence rates among registries. The harmonization of data in relation to operational differences between registries is the next step in developing the common ReLAMC database.

New Approach to Multivariate Standard Addition Based on Multivariate Curve Resolution by Alternating Least-Squares: Application to Voltammetric Data.

A multivariate version of the classical univariate standard addition method is proposed for the analysis of samples generating overlapping signals in the presence of notorious matrix effects. Unlike previous versions based on multivariate calibration by partial least-squares (PLS), the proposed strategy takes advantage of a self-modeling methodology: multivariate curve resolution by alternating least-squares (MCR-ALS) enhanced with signal shape constraints based on parametric functions. In this way, there is no need for the full multivariate response of a blank solution, and in multianalyte determinations, the standard additions can be made with a solution containing all of the analytes, which constitutes a clear advance as compared to PLS approach. The proposed method has been successfully tested in the voltammetric determination of hydroquinone and catechol in solutions of increasing complexity and appears to be a promising tool in the field of electroanalysis.

RISK FACTORS FOR HYPOGLYCEMIA IN INPATIENTS WITH TOTAL PARENTERAL NUTRITION AND TYPE 2 DIABETES: A POST HOC ANALYSIS OF THE INSUPAR STUDY.

Objective: Treatment of hyperglycemia with insulin is associated with increased risk of hypoglycemia in type 2 diabetes mellitus (T2DM) patients receiving total parenteral nutrition (TPN). The aim of this study was to determine the predictors of hypoglycemia in hospitalized T2DM patients receiving TPN. Methods: Post hoc analysis of the INSUPAR study, which is a prospective, open-label, multicenter clinical trial of adult inpatients with T2DM in a noncritical setting with indication for TPN. Results: The study included 161 patients; 31 patients (19.3%) had hypoglycemic events, but none of them was severe. In univariate analysis, hypoglycemia was significantly associated with the presence of diabetes with end-organ damage, duration of diabetes, use of insulin prior to admission, glycemic variability (GV), belonging to the glargine insulin group in the INSUPAR trial, mean daily grams of lipids in TPN, mean insulin per 10 grams of carbohydrates, duration of TPN, and increase in urea during TPN. Multiple logistic regression analysis showed that the presence of diabetes with end-organ damage, GV, use of glargine insulin, and TPN duration were risk factors for hypoglycemia. Conclusion: The presence of T2DM with end-organ damage complications, longer TPN duration, belonging to the glargine insulin group, and greater GV are factors associated with the risk of hypoglycemia in diabetic noncritically ill inpatients with parenteral nutrition. Abbreviations: ADA = American Diabetes Association; BMI = body mass index; CV% = coefficient of variation; DM = diabetes mellitus; GI = glargine insulin; GV = glycemic variability; ICU = intensive care unit; RI = regular insulin; T2DM = type 2 diabetes mellitus; TPN = total parenteral nutrition.

Clinical association of metabolic syndrome, C-reactive protein and testosterone levels with clinically significant prostate cancer.

Recently, the influence that metabolic syndrome (MetS), hormonal alterations and inflammation might have on prostate cancer (PCa) risk has been a subject of controversial debate. Herein, we aimed to investigate the association between MetS-components, C-reactive protein (CRP) and testosterone levels, and the risk of clinically significant PCa (Sig-PCa) at the time of prostate biopsy. For that, men scheduled for transrectal ultrasound guided biopsy of the prostate were studied. Clinical, laboratory parameters and criteria for MetS characterization just before the biopsy were collected. A total of 524 patients were analysed, being 195 (37.2%) subsequently diagnosed with PCa and 240 (45.8%) meet the diagnostic criteria for MetS. Among patients with PCa, MetS-diagnosis was present in 94 (48.2%). Remarkably, a higher risk of Sig-PCa was associated to MetS, greater number of MetS-components and higher CRP levels (odds-ratio: 1.83, 1.30 and 2.00, respectively; P < 0.05). Moreover, higher circulating CRP levels were also associated with a more aggressive Gleason score in PCa patients. Altogether, our data reveal a clear association between the presence of MetS, a greater number of MetS-components or CRP levels >2.5 mg/L with an increased Sig-PCa diagnosis and/or with aggressive features, suggesting that MetS and/or CRP levels might influence PCa pathophysiology.

CE-MS-based urinary biomarkers to distinguish non-significant from significant prostate cancer.

BACKGROUND: Prostate cancer progresses slowly when present in low risk forms but can be lethal when it progresses to metastatic disease. A non-invasive test that can detect significant prostate cancer is needed to guide patient management. METHODS: Capillary electrophoresis/mass spectrometry has been employed to identify urinary peptides that may accurately detect significant prostate cancer. Urine samples from 823 patients with PSA (<15 ng/ml) were collected prior to biopsy. A case-control comparison was performed in a training set of 543 patients (nSig = 98; nnon-Sig = 445) and a validation set of 280 patients (nSig = 48, nnon-Sig = 232). Totally, 19 significant peptides were subsequently combined by a support vector machine algorithm. RESULTS: Independent validation of the 19-biomarker model in 280 patients resulted in a 90% sensitivity and 59% specificity, with an AUC of 0.81, outperforming PSA (AUC = 0.58) and the ERSPC-3/4 risk calculator (AUC = 0.69) in the validation set. CONCLUSIONS: This multi-parametric model holds promise to improve the current diagnosis of significant prostate cancer. This test as a guide to biopsy could help to decrease the number of biopsies and guide intervention. Nevertheless, further prospective validation in an external clinical cohort is required to assess the exact performance characteristics.

eHealth Familias Unidas: Efficacy Trial of an Evidence-Based Intervention Adapted for Use on the Internet with Hispanic Families.

While substance use and sexual risk behaviors among Hispanic youth continue to be public health concerns, few evidence-based preventive interventions are developed for and implemented with Hispanic/Latino youth. The objective of this study was to evaluate the efficacy of eHealth Familias Unidas, an Internet adaptation of an evidence-based family intervention for Hispanics. A randomized controlled trial design (n = 230) was used to evaluate intervention effects on substance use and condomless sex among a sample of Hispanic eighth graders with behavioral problems. Participants were randomized to eHealth Familias Unidas (n = 113) or prevention as usual (n = 117) and assessed at baseline and 3 and 12 months post baseline. We trained mental health school personnel and community mental health professionals to recruit and deliver the Internet-based intervention with Hispanic families. It was hypothesized that, over time, eHealth Familias Unidas would be more efficacious than prevention as usual in reducing drug use (marijuana, cocaine, inhalants, and other drugs), prescription drug use, cigarette use, alcohol use, and condomless sex and that these changes would be mediated by family functioning. Significant intervention effects were found across time for drug use, prescription drug use, and cigarette use. While eHealth Familias Unidas positively affected family functioning, mediation effects were not found. This study demonstrated that family-based eHealth interventions can be efficacious among Hispanic populations when delivered in community settings.

[Spontaneous dissection of visceral arteries. A series of cases]. / Disección espontánea de arterias viscerales: reporte de una serie de casos.

BACKGROUND: Spontaneous dissections of visceral arteries are rare and usually secondary to other disease. There is paucity of information about their natural course. AIM: To describe the imaging, clinical characteristics and follow-up of spontaneous visceral artery dissections diagnosed at our institution. MATERIAL AND METHODS: We report a series of 14 patients in whom a spontaneous dissection of a visceral artery was diagnosed on abdominal angio-CT between 2010 and 2018. Clinical features and evolution were recorded. RESULTS: Isolated lesions of the celiac axis were the most common finding. Multiple territories were involved in 14% of cases. A dissection flap was observed in four cases, a hematoma-dissection complex in seven and an aneurysmal dilatation associated with the dissection in three. Of the 10 patients who were followed at our institution, 90% had stabilization or partial regression of the imaging findings. In the remaining case, new dissection events were observed. All cases were managed conservatively, and no death was reported. CONCLUSIONS: In this series of patients, spontaneous dissection of visceral arteries had a benign, favorable course, requiring only conservative management.

Plasma ghrelin O-acyltransferase (GOAT) enzyme levels: A novel non-invasive diagnosis tool for patients with significant prostate cancer.

Early detection of PCa faces severe limitations as PSA displays poor-specificity/sensitivity. As we recently demonstrated that plasma ghrelin O-acyltransferase (GOAT)-enzyme is significantly elevated in PCa-patients compared with healthy-controls, using a limited patients-cohort, we aimed to further explore the potential of GOAT to improve PCa diagnosis using an ample patients-cohort (n = 312) and defining subgroups (i.e. significant PCa/metastatic patients, etc.) that could benefit from this biomarker. Plasma GOAT-levels were evaluated by ELISA in patients with (n = 183) and without (n = 129) PCa. Gleason Score ≥ 7 was considered clinically significant PCa. GOAT-levels were higher in PCa patients vs control patients, and in those with significant PCa vs non-significant PCa. GOAT-levels association with the diagnoses of significant PCa was independent from traditional clinical variables (i.e. PSA/age/DRE). Remarkably, GOAT outperformed PSA in patients with PSA-levels ranging 3-20 ng/mL for the significant PCa diagnosis [GOAT-AUC = 0.612 (0.531-0.693) vs PSA-AUC = 0.494 (0.407-0.580)]. A panel of key variables including GOAT/age/DRE/testosterone also outperformed the same panel but with PSA [AUC = 0.720 (0.710-0.730) vs AUC = 0.705 (0.695-0.716), respectively]. Notably, GOAT-levels could also represent a novel predictive biomarker of aggressiveness, as its levels are positively associated with Gleason Score and the presence of metastasis at the time of diagnoses. Altogether, our data reveal that GOAT-levels can be used as a non-invasive biomarker for significant PCa diagnosis in patients at risk of PCa (with PSA: 3-20 ng/mL).

Psychometric properties of the Italian version of the Cognitive Reserve Scale (I-CRS).

The original definition of cognitive reserve (CR) refers to the individual differences in cognitive performance after a brain damage or pathology. Several proxies were proposed to evaluate CR (education, occupational attainment, premorbid IQ, leisure activities). Recently, some scales were developed to measure CR taking into account several cognitively stimulating activities. The aim of this study is to adapt the Cognitive Reserve Scale (I-CRS) for the Italian population and to explore its psychometric properties. I-CRS was administered to 547 healthy participants, ranging from 18 to 89 years old, along with neuropsychological and behavioral scales to evaluate cognitive functioning, depressive symptoms, and apathy. Cronbach's α, corrected item-total correlations, and the inter-item correlation matrix were calculated to evaluate the psychometric properties of the scale. Linear regression analysis was performed to build a correction grid of the I-CRS according to demographic variables. Correlational analyses were performed to explore the relationships between I-CRS and neuropsychological and behavioral scales. We found that age, sex, and education influenced the I-CRS score. Young adults and adults obtained higher I-CRS scores than elderly adults; women and participants with high educational attainment scored higher on I-CRS than men and participants with low education. I-CRS score correlated poorly with cognitive and depression scale scores, but moderately with apathy scale scores. I-CRS showed good psychometric properties and seemed to be a useful tool to assess CR in every adult life stage. Moreover, our findings suggest that apathy rather than depressive symptoms may interfere with the building of CR across the lifespan.
