Adolescent environmental enrichment induces social resilience and alters neural gene expression in a selectively bred rodent model with anxious phenotype.

Stress is a major influence on mental health status; the ways that individuals respond to or copes with stressors determine whether they are negatively affected in the future. Stress responses are established by an interplay between genetics, environment, and life experiences. Psychosocial stress is particularly impactful during adolescence, a critical period for the development of mood disorders.

Some 161 patients, 18-65 years of age diagnosed with uncomplicated urogenital, rectal, or pharyngeal gonorrhoea by nucleic acid amplification test (NAAT) were randomized to treatment with single dose of cefixime 800 mg plus doxycycline 100 mg twice a day for 1 week or a single dose of ceftriaxone 1 g intramuscularly plus single dose of azithromycin 2 g.

Outcomes of Emergency Parastomal Hernia Repair in Older Adults: A Retrospective Analysis.

Introduction: Parastomal hernias are common and many are never repaired. Emergency parastomal hernia repair (PHR) is a feared complication following ostomy creation, yet the incidence and long-term outcomes of emergency PHR are unknown.

Materials And Methods: We performed a retrospective analysis of 100% Medicare claims data (2007-2015) to evaluate complications, readmissions, reoperations, hospitalizations, and mortality after emergency PHR.

Serum TGF-1 and CD14 Predicts Response to Anti-TNF- Therapy in IBD.

Background: Tumor necrosis factor-alpha (TNF-) agonists revolutionized therapeutic algorithms in inflammatory bowel disease (IBD) management. However, approximately every third IBD patient does not respond to this therapy in the long term, which delays efficient control of the intestinal inflammation.

Methods: We analyzed the power of serum biomarkers to predict the failure of anti-TNF-.

Methylation analysis as an auxiliary tool in cytological diagnostics of infrequent anogenital lesions - a pilot study.

Methylation silencing of certain cellular genes is a sign of carcinogenesis progression and therefore tests that detect methylation could be used in the diagnosis or staging of malignant diseases. In the diagnosis of squamous cell carcinomas of the cervix which are almost 100% caused by long-term infection with highrisk human papillomavirus (HR-HPV), methylation silencing of certain cellular genes is a highly specific marker of advanced dysplastic lesions and appears to result from aberrant activation of the methyltransferase DNMT1 by viral oncoproteins E6 and E7. A methylation test performed on a cervicovaginal cytology specimen allows to increase the diagnostic value of this non-invasive test and to select patients with severe squamous cell lesions for follow-up.

Paradoxical Reactions to Anti-TNFα and Anti-IL-17 Treatment in Psoriasis Patients: Are Skin and/or Gut Microbiota Involved?

Psoriasis is a chronic, immune-mediated, inflammatory disease primarily affecting the skin. It is currently coming to light that patients with psoriasis have disrupted intestinal barrier and often suffer from comorbidities associated with the gastrointestinal tract. Moreover, there is growing evidence of both cutaneous and intestinal paradoxical reactions during biologic treatment in patients with psoriasis.

Contemporary Outcomes of Elective Parastomal Hernia Repair in Older Adults.

Importance: Parastomal hernia is a challenging complication following ostomy creation; however, the incidence and long-term outcomes after elective parastomal hernia repair are poorly characterized.

Objective: To describe the incidence and long-term outcomes after elective parastomal hernia repair.

Design, Setting, And Participants: Using 100% Medicare claims, a retrospective cohort study of adult patients who underwent elective parastomal hernia repair between January 1, 2007, and December 31, 2015, was performed.

Comparative Outcomes of Groin Hernia Repair by Sex Among Medicare Beneficiaries.

Objective: To compare the rates of operative recurrence between male and female patients undergoing groin hernia repair.

Background Data: Groin hernia repair is common but understudied in females. Limited prior work demonstrates worse outcomes among females.

Skin microbiota signature distinguishes IBD patients and reflects skin adverse events during anti-TNF therapy.

Crohn's disease (CD) and ulcerative colitis (UC) are two forms of inflammatory bowel disease (IBD), where the role of gut but not skin dysbiosis is well recognized. Inhibitors of TNF have been successful in IBD treatment, but up to a quarter of patients suffer from unpredictable skin adverse events (SkAE). For this purpose, we analyzed temporal dynamics of skin microbiota and serum markers of inflammation and epithelial barrier integrity during anti-TNF therapy and SkAE manifestation in IBD patients.

Association between ustekinumab therapy and changes in specific anti-microbial response, serum biomarkers, and microbiota composition in patients with IBD: A pilot study.

Background: Ustekinumab, is a new therapy for patients with IBD, especially for patients suffering from Crohn's disease (CD) who did not respond to anti-TNF treatment. To shed light on the longitudinal effect of ustekinumab on the immune system, we investigated the effect on skin and gut microbiota composition, specific immune response to commensals, and various serum biomarkers.

Methodology/principal Findings: We recruited 11 patients with IBD who were monitored over 40 weeks of ustekinumab therapy and 39 healthy controls (HC).

Variation in the Diagnosis of Noninvasive Follicular Thyroid Neoplasm with Papillary-like Nuclear Features.

Context: Noninvasive encapsulated follicular variant of papillary thyroid cancer was reclassified as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) in January 2017. The impact of this nomenclature change at a population level remains unknown.

Objective: Examine use of NIFTP across different US regions and populations.

Prevalence of genital and oral human papillomavirus infection among psoriasis patients on biologic therapy.

Current knowledge about human papillomavirus (HPV) infection in psoriasis patients treated with biologics is limited. In this study we evaluated the prevalence of oral and genital HPV infection in psoriasis patients treated with biologics or topical therapy for at least 6 months. The presence of HPV DNA in oral rinse and genital smears was evaluated.

Invasive Aspergillus infection of middle ear in a patient treated with secukinumab, methotrexate, and corticosteroids for psoriasis and psoriatic arthritis.

Mucocutaneous mycotic infections are common complications in patients on IL-17 inhibitor therapy. We report a case of a 33-year-old male with severe psoriasis and psoriatic arthritis on secukinumab combined with methotrexate and prednisone with swelling, otorrhea, and pain of the right ear and external auditory canal. Due to progressive hypacusis, a surgical solution was chosen.

Fecal Microbiome Changes and Specific Anti-Bacterial Response in Patients with IBD during Anti-TNF Therapy.

Inflammatory bowel diseases (IBD) are chronic disorders of the gastrointestinal tract that have been linked to microbiome dysbiosis and immune system dysregulation. We investigated the longitudinal effect of anti-TNF therapy on gut microbiota composition and specific immune response to commensals in IBD patients. The study included 52 patients tracked over 38 weeks of therapy and 37 healthy controls (HC).

Prevalence of high-risk human papillomavirus DNA and mRNA and its association with abnormal anal cytology in the Czech male anal cancer screening cohort.

Background: Anal cancer (AC) screening is justified in high-risk populations, particularly HIV-positive men having sex with men (MSM). HR-HPV testing could improve the efficiency of cytologically based screening of AC, as in the screening of biologically analogical cervical cancer. The specificity of HR-HPV testing is influenced by the prevalence of HR-HPV infection in the screened population.
