Clinical Correlates of Non-Suicidal Self-Injury (NSSI) in an Outpatient Sample of Adolescents

Non-suicidal self-injury (NSSI) in adolescents is a major public health concern. The first goal of our study was to describe the characteristics and functions of NSSI and NSSI thoughts in an adolescent outpatient sample. The second goal was to examine which clinical factors discriminate between these two groups of patients. A group of 267 subjects was recruited from the Adolescent Outpatient Psychiatric Services, Jiménez Díaz Foundation (Madrid, Spain) from November 2011 to October 2012. All participants were administered the Spanish version of the Self-Injurious Thoughts and Behaviors Interview (SITBI). A total of 21.7% of patients reported having engaged in NSSI at least once in their lifetime. The most strongly endorsed function for NSSI was automatic negative reinforcement. In comparison with patients in the NSSI Thoughts group and the control group, patients in the NSSI group scored higher in Internalization of Anger and in all the scales comprising the Children's Depression Inventory. Our findings on the prevalence and functions of NSSI are consistent with the literature. NSSI was mainly performed for emotion regulation purposes; specifically, NSSI seems to be used to cope with anger and depression. In addition, internalization of anger might play a significant role in the maintenance of this behavior.     

Usefulness of Lung Ultrasound in Neonatal Congenital Heart Disease (LUSNEHDI): Lung Ultrasound to Assess Pulmonary Overflow in Neonatal Congenital Heart Disease

This study aimed to explore the pattern of lung ultrasound (LUS) in newborns with congenital heart disease (CHD) and to investigate the accuracy of LUS assessing pulmonary overflow (PO) during the first days of life. Lung ultrasound was performed in 51 newborns during the first days of life, and newborns were classified in two groups depending on the predisposition to develop POas evaluated by the abundance of B-lines. The results were compared to the physical examination (PE), chest X-ray, and echocardiography. In both groups there were no differences in abundance of B-lines during the first days of life, but those with a type of CHD with a trend to develop PO had a higher B-lines score after 72 h (p < 0.05) with a good correlation with echocardiography findings and with a better sensibility than PE and chest X-ray. We found that LUS is a reliable tool for the diagnosis of PO and may be useful to monitor and optimize therapy, which should be further validated in multicentre studies.     

Arguments Used in Public Comments to Support or Oppose the US Department of Agriculture’s Minimum Stocking Requirements: A Content Analysis

Background

In 2016, the US Department of Agriculture (USDA)’s Supplemental Nutrition Assistance Program (SNAP) Retailer Rule proposed several changes for SNAP-authorized retailers, including: requiring retailers to have at least 85% of their food sales come from items that are not cooked or heated on site before or after purchase; requiring stores to stock seven varieties of qualifying foods from four staple food groups; requiring stores to carry perishable foods in three of the four staple groups; requiring stores to carry six units of qualifying foods at all times (depth of stock); disqualifying multiple ingredient foods and accessory foods from counting toward depth of stock requirements.

Pathobiology of Lomentospora prolificans: could this species serve as a model of primary antifungal resistance?

The number of fungal isolates resistant to antifungal drugs has increased dramatically over the last few years and has become an important concern for clinicians. Among these isolates, fungi showing multidrug resistance are particularly worrying because of the difficulties associated with their treatment. These factors hamper the successful recovery of patients and drastically raise mortality rates. Antifungal resistance is multifactorial and several mechanisms in different fungi have been described. There is a need to study these mechanisms in depth; however, the study of antifungal drug resistance separately for each individual species makes progress in the field very slow and tedious. The selection of a multiresistant microorganism as a model for understanding resistance mechanisms and extrapolating the results to other species could help in the search for a solution. In this mini-review, we describe the pathobiology of Lomentospora (Scedosporium) prolificans, paying special attention to its intrinsic resistance to all currently available antifungal agents. The characteristics of L. prolificans offer several advantages: the possibility of using a single microorganism for the study of resistance to different drugs, even cases of double and triple resistance; it is biologically safe for society in general as no new genetically–modified strains are needed for the experiments; it is homologous with other fungal species, and there is repetitiveness between different strains. In conclusion, we propose L. prolificans as a candidate for consideration as a fungal model for the study of resistance mechanisms against antifungal agents.     

Oral complication risks after invasive and non-invasive dental procedures in HIV-positive patients

BACKGROUND: Limited published scientific evidence is available to provide guidance to clinicians on possible increased risks of invasive oral procedures associated with the human immunodeficiency virus (HIV) status of the patient. The aim of this study was to assess post-procedural complications in patients infected with HIV. MATERIAL AND METHODS: This was a retrospective cross-sectional study of the records of 101 consecutive HIV patients treated at the School of Dentistry of Madrid Complutense University and Sandoval STD Clinic in Madrid between January 2003 and February 2005. Data were gathered by an experienced dental practitioner using a structured epidemiological questionnaire for information on gender, age, HIV transmission category, medical history, hepatitis B virus (HBV) or hepatitis C virus (HCV) coinfection and other diseases, TCD4+ and TCD8+ count, HIV viral load (VL), platelet count, neutrophil count, international normalized ratio and haemoglobin level; tobacco and alcohol intake, highly active antiretroviral treatment and presence of oral lesions. Information was also collected on complications related to dental treatment (invasive or non-invasive) during the previous 6 months. Chi-squared test and Fisher's exact test were used to establish statistical significance. RESULTS: Data were gathered on 314 dental procedures in 101 patients. The overall complication rate was 2.2% (7/314); in 147 invasive procedures, seven complications (4.8%) were documented (one persistent pain, two prolonged bleeding, three infections, one bone sequestrum) including extractions, periodontal scaling, endodontic treatment and biopsy. No differences were found in TCD4+, TCD8+, platelet count, HBV or HCV co-infections or HIV VL between patients with and/or without complications. Patients with complications were mainly in B stage of HIV disease (P=0.020). Oral lesions and smoking habit>20 cig day-1 were documented in 83.3% (P=0.086) and 50% (P=0.060), respectively, of patients with complications. CONCLUSIONS: The complication rate was 2.2% overall and 4.8% after invasive dental procedures. Presence of oral lesions, smoking habit or HIV clinical stage B may be predictive factors for oral complications in HIV patients. No relationship was found between complications and virological, immunological or other laboratory values. Studies with wider samples and negative control group are warranted to confirm the absence of an association between HIV positivity and higher risk of oral complications.     

Antinuclear antibodies (ANA) screening by enzyme immunoassay with nuclear HEp-2 cell extract and recombinant antigens: analytical and clinical evaluation

OBJECTIVES: Immunofluorescence assay (IFA) has been the standard method for antinuclear antibodies (ANA). To simplify and standardize the ANA test, generic ANA solid phase enzyme immunoassay has been promoted. The objective of the present work has been to study the relationship with IFA and the clinical usefulness of a generic EIA for ANA (COBAS Core HEp-2 ANA EIA, Roche Diagnostics). DESIGNS AND METHODS: We studied 74 healthy individuals, 119 patients with defined systemic autoimmune diseases, 26 patients with other autoimmune diseases, and 490 routine samples sent to laboratory for ANA analysis. RESULTS: Precision study showed intra-assay coefficient of variations (CVs) below 8% and inter-assay CVs below 10%. In relation to IFA, a 0.6 kappa index of agreement was obtained. COBAS-ANA concentrations increased according to IFA titer and greatest COBAS-ANA responses were obtained with pure or mixed homogeneous patterns and centromeric patterns. Analysis of COBAS-ANA response to particular antigenic specificities showed that SS-B, Scl-70 and U1sn-RNP specificities were saturating at high concentrations, whereas Jo-1, SS-A and nuclear and centromeric specificities exhibited lower responses. Elevated serum concentrations of IgG and IgM did not interfere COBAS-ANA, but high serum rheumatoid factor (RF) concentrations produced a decrease of ANA. For systemic lupus erythematosus (SLE) patients, the COBAS-ANA best efficiency was obtained with a cut-off of 0.9, with a sensitivity of 97% and a specificity of 88%, whereas the best IFA-ANA efficiency was obtained with a 1:80 dilution, giving a sensitivity of 90% and a specificity of 99%. There were no differences between areas under ROC curves for COBAS-ANA and IFA-ANA. For other systemic and nonsystemic autoimmune diseases sensitivity and specificity of COBAS-ANA were similar or higher than that of 1:160 IFA-ANA titer. CONCLUSION: Sensitivity and specificity of COBAS Core ANA-EIA for SLE and other systemic and nonsystemic autoimmune diseases, together with performance characteristics make it an adequate automated system for ANA screening.     

Appendectomy in Third Trimester of Pregnancy and Birth Outcomes: A Propensity Score Analysis of a 6-Year Cohort Study Using Administrative Claims Data

Introduction

While there is evidence of obstetric and neonatal outcomes from non-obstetric surgery during pregnancy, surgery during the third trimester of gestation has not been evaluated as a prognostic factor for those outcomes. The objective of this study was to determine whether appendectomies during the third trimester are associated with adverse neonatal outcomes, in comparison with appendectomies during the first two trimesters, based on national administrative data in Colombia.

Methods

A retrospective cohort study was performed using administrative health records. It included all women who had live births and who underwent an appendectomy during any stage of pregnancy, between the years 2011 and 2016, and who belonged to Colombia’s contributory health system. The main outcome was preterm birth. Birth weight and 1-min and 5-min Apgar scores were also measured, as well as outcomes used to identify neonatal near-miss cases. Propensity score matching was used in order to balance baseline characteristics (age, weeks of gestation, obstetric comorbidity index, and region and year the procedure was performed). Relative risks were estimated with Poisson regressions.

Results

This study included a total of 2507 women in Colombia’s contributory health system who underwent an appendectomy during pregnancy. Appendectomy was performed on 885 women (35.30%) in their first trimester, 1205 women (48.07%) in their second trimester, and 417 women (16.63%) in their third trimester. For the entire population, the preterm birth rate was 11.85 per 100 appendectomies. With the matched sample, this study found that women in their third trimester had a 1.65 greater risk of preterm birth [95% CI, 1.118–2.423], a 3.43 greater risk of birth at gestational ages < 33 weeks [95% CI, 1.363 to 8.625], 2.083 greater risk of weight under 1750 g [95% CI, 1.056–4.109], and a mean difference of − 0.247 [95% CI, − .382 to − .112] in the 1-min Apgar score and − .168^a [95% CI, − .276 to − .060] in the 5-min Apgar. No differences were found in birth weight or Apgar scores < 7.

Conclusions

In Colombia’s contributory health system, women who undergo appendectomies in their third trimester have a greater risk of preterm birth, birth weight under 1750 g, birth at gestational ages less than 33 weeks, and decreased 1-min and 5-min Apgar scores.
