Transcriptome-informed identification and characterization of - and -isoprenyl diphosphate synthase genes.

Insect physiology and reproduction depend on several terpenoid compounds, whose biosynthesis is mainly unknown. One enigmatic group of insect monoterpenoids are mealybug sex pheromones, presumably resulting from the irregular coupling activity of unidentified isoprenyl diphosphate synthases (IDSs). Here, we performed a comprehensive search for IDS coding sequences of the pest mealybug .

Mpox in people with past infection or a complete vaccination course: a global case series.

Background: Since May, 2022, a large global outbreak of human mpox (formerly known as monkeypox) has predominantly affected men who have sex with men. The strain responsible, Clade IIb, has mutated substantially from precursors originating from the 2017-18 outbreak in Nigeria. Immunity to smallpox, another orthopoxvirus, via previous infection or vaccination provides lifelong immunity.

Increasing of New CA-MRSA Infections Detected in people living with HIV Who Engage in Chemsex in Barcelona: An Ambispective Study.

Introduction: There are no data on community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections in the context of the chemsex phenomenon. This study aimed to characterize CA-MRSA-related infections in a cohort of people living with HIV (PLWH) who engage in chemsex.

Methods: At the Hospital Clinic of Barcelona, from February 2018 to January 2022, we analyzed CA-MRSA infections diagnosed in a cohort of PLWH who engage in chemsex.

Mpox - Formerly Monkey Pox - in Dermatology: A Review of Epidemiologic Features, Clinical Presentation, Diagnosis, and Treatment.

Mpox is an emerging zoonotic disease that has spread rapidly around the world. It has been declared a public health emergency of international concern by the World Health Organization. This review is an update for dermatologists on the epidemiology, clinical presentation, diagnosis, and treatment of Mpox.

Pain and late-onset of hidradenitis suppurativa can have a negative influence on occupational status and educational level. A cross-sectional study.

Background And Objectives: Hidradenitis suppurativa (HS) is a chronic and painful condition with negative impact on daily activity. Little information on the impact of disease-specific factors on educational level and occupational status in hidradenitis suppurativa patients has been reported. We sought to identify how disease-specific factors could influence occupational status and educational level in patients with HS.

Pain and Late-Onset of Hidradenitis Suppurativa Can Have a Negative Influence on Occupational Status and Educational Level. A Cross-Sectional Study.

Background And Objectives: Hidradenitis suppurativa is a chronic and painful condition with negative impact on daily activity. Little information on the impact of disease-specific factors on educational level and occupational status in hidradenitis suppurativa patients has been reported. We sought to identify how disease-specific factors could influence occupational status and educational level in patients with hidradenitis suppurativa.

Monkeypox outbreak in Spain: clinical and epidemiological findings in a prospective cross-sectional study of 185 cases.

Background: Since May 2022, a new outbreak of monkeypox has been reported in several countries, including Spain. The clinical and epidemiological characteristics of the cases in this outbreak may differ from those in earlier reports.

Objectives: To document the clinical and epidemiological characteristics of cases of monkeypox in the current outbreak.

Frequent detection of monkeypox virus DNA in saliva, semen, and other clinical samples from 12 patients, Barcelona, Spain, May to June 2022.

A monkeypox (MPX) outbreak has expanded worldwide since May 2022. We tested 147 clinical samples collected at different time points from 12 patients by real-time PCR. MPX DNA was detected in saliva from all cases, sometimes with high viral loads.

Short-term effectiveness and tolerability of carbon dioxide laser for anal high-grade squamous intraepithelial lesions in individuals living with HIV.

Background: Ablative treatment of intra-anal high-grade squamous intraepithelial lesions (HSIL) reduces the risk of progression to anal squamous cell carcinoma. Our objective was to assess the short-term effectiveness and tolerability of the carbon dioxide laser for treating intra-anal HSIL in patients at high risk of anal cancer.

Methods: This is an exploratory, pilot, single-arm, clinical trial of treatment response for anal HSIL in people living with HIV diagnosed with ≤3 not previously treated HSILs.

Pharmacological modulation of fish-induced depth selection in D. magna: the role of cholinergic and GABAergic signalling.

Animal behaviour is closely related to individual fitness, which allows animals to choose suitable mates or avoid predation. The central nervous system regulates many aspects of animal behaviour responses. Therefore, behavioural responses can be especially sensitive to compounds with a neurodevelopmental or neurofunctional mode of action.

Response factors associated with electrocautery treatment of intra-anal high-grade squamous intraepithelial lesions in a population of HIV-positive men who have sex with men.

Background: Ablative treatment of anal high-grade squamous intraepithelial lesions (HSIL) reduces the risk of progression to anal squamous cell carcinoma.

Objectives: To identify factors that influence the response to treatment of anal HSIL by electrocautery ablation (ECA) in a population of HIV-positive men who have sex with men (MSM).

Design: Retrospective study of ECA treatment response in a prospectively followed anal dysplasia cohort.

Effective Treatment of Lymphogranuloma venereum Proctitis With Azithromycin.

Background: Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by Chlamydia trachomatis (CT) serovars L1, L2, and L3 and is endemic among men who have sex with men (MSM) in Europe. We evaluated weekly oral azithromycin 1 g for 3 weeks as a treatment for LGV proctitis.

Methods: This is an open clinical trial with convenience allocation according to treating physician preferences.

Characterization of neurotransmitters and related metabolites in Daphnia magna juveniles deficient in serotonin and exposed to neuroactive chemicals that affect its behavior: A targeted LC-MS/MS method.

Neurotransmitters are endogenous metabolites that play a crucial role within an organism, at the chemical synapses. There is a growing interest in their analytical determination for understanding the neurotoxic effect of contaminants. Daphnia magna represents an excellent aquatic model for these environmental studies, due to its similarities with vertebrates in several neurotransmitters and related gene pathways and because of its wide application in ecotoxicological studies.

Changes in lipid profiles in Daphnia magna individuals exposed to low environmental levels of neuroactive pharmaceuticals.

Disruptive effects of chemicals on lipids in aquatic species are mostly limited to obesogens and vertebrates. Recent studies reported that antidepressants, anxiolytic, antiepileptic and β-adrenergic pharmaceuticals, with putative distinct mechanisms of action at low environmental relevant concentrations, up-regulated common neurological and lipid metabolic pathways and enhanced similarly reproduction in the crustacean Daphnia magna. Conversely CRISPR mutants for the tryptophan hydrolase enzyme gene (TRH) that lack serotonin had the opposed phenotype: the lipid metabolism down-regulated and impaired reproduction.
