Neisseria gonorrhoeae has developed resistance to all first-line recommended therapies, making gonococcal antimicrobial resistance a major public health concern given limited antibiotic options currently and an even smaller antimicrobial development pipeline. Since the release of the Centers for Disease Control and Prevention (CDC) 2015 STD Treatment Guidelines, azithromycin, part of the 2015 dual-drug treatment regimen, has had a rapid rise in resistance. The 2020 CDC Gonorrhea Treatment Recommendations and the 2021 Sexually Transmitted Infections (STI) Treatment Guidelines were developed weighing the priorities of treating the individual, protecting the population, and preventing antimicrobial resistance.

Gonorrhea subject matter experts (SME) generated 8 key questions and conducted a literature review of updated data from 2013 to 2019 on gonorrhea antimicrobial resistance, treatment failures, clinical trials, and other key topics. More than 2200 abstracts were assessed, and 248 clinically relevant artiies exist for persons with cephalosporin allergies; there are no recommended alternative therapies for N gonorrhoeae infection of the throat.
The 2021 CDC STI Treatment Guidelines now recommend 500mg ceftriaxone intramuscularly once for the treatment of uncomplicated gonorrhea at all anatomic sites. If coinfection with chlamydia has not been excluded, cotreatment with doxycycline 100mg twice daily for 7 days should be added. Few alternative therapies exist for persons with cephalosporin allergies; there are no recommended alternative therapies for N gonorrhoeae infection of the throat.Genital herpes, caused by herpes simplex virus (HSV) type 1 or type 2, is a prevalent sexually transmitted infection (STI). Given that HSV is an incurable infection, there are important concerns about appropriate use of diagnostic tools, management of infection, prevention of transmission to sexual partners, and appropriate counseling. In preparation for updating the Centers for Disease Control and Prevention (CDC) STI treatment guidelines, key questions for management of genital herpes infection were developed with a panel of experts. To answer these questions, a systematic literature review was performed, with tables of evidence including articles that would change guidance assembled. These data were used to inform recommendations in the 2021 CDC STI treatment guidelines.A panel of experts generated 5 "key questions" in the management of adult syphilis. A systematic literature review was conducted and tables of evidence were constructed to answer these questions. Available data suggest no clinical benefit to >1 dose of benzathine penicillin G for early syphilis in human immunodeficiency virus (HIV)-infected patients. While penicillin remains the drug of choice to treat syphilis, doxycycline to treat early and late latent syphilis is an acceptable alternate option if penicillin cannot be used. selleck products There are very limited data regarding the impact of additional antibiotic doses on serologic responses in serofast patients and no data on the impact of additional antibiotic courses on long-term clinical outcomes. In patients with isolated ocular or otic signs and symptoms, reactive syphilis serologic results, and confirmed ocular/otic abnormalities at examination, a diagnostic cerebrospinal fluid (CSF) examination is not necessary, because up to 40% and 90% of patients, respectively, would have no CSF abnormalities. Based on the results of 2 studies, repeated CSF examinations are not necessary for HIV-uninfected patients or HIV-infected patients on antiretroviral therapy who exhibit appropriate serologic and clinical responses after treatment for neurosyphilis. Finally, several important gaps were identified and should be a priority for future research.In preparation for the 2021 Centers for Disease Control and Prevention (CDC) sexually transmitted infections (STIs) treatment guidelines, the CDC convened an advisory group in 2019 to examine recent literature addressing updates in the epidemiology, diagnosis, and management of STIs. This article summarizes recent data in each of these key topic areas as they pertain to bacterial vaginosis (BV), the most common cause of vaginal discharge. The evidence reviewed primarily focused on updates in the global epidemiology of BV, risk factors for BV, data supportive of sexual transmission of BV-associated bacteria, BV molecular diagnostic tests, and novel treatment regimens. Additionally, recent literature on alcohol abstinence in the setting of 5-nitroimidazole use was reviewed.
Vulvovaginal candidiasis (VVC) is a common cause of vulvovaginal itching and discharge. This article discusses the latest CDC STI Treatment Guidelines for VVC.

A literature search of relevant topics was performed, and a team of experts was convened to discuss (1) diagnosis/testing modalities; treatment of (2) uncomplicated VVC , (3) complicated VVC, and (4) VVC caused by non-albicans yeast; (5) alternative treatment regimens; (6) susceptibility testing of yeast; Special Populations (7) pregnancy and (8) HIV and VVC.

Yeast culture remains the gold standard for diagnoses. Newer molecular assays have been developed for the diagnosis of VVC and perform well. Azole antifungals remain the treatment of choice for uncomplicated VVC. Two new drugs, TOL-463 and recently FDA-approved ibrexafungerp, appeared promising in clinical trials. For recurrent VVC, oteseconazole, not yet commercially available, may represent a new option. For non-albicans yeast infections in symptomatic patients, boric acid appears useful. No evidence supports the use of alternative treatments, including probiotics. Fluconazole during pregnancy may be associated with spontaneous abortion and craniofacial and heart defects. In women with HIV infection, lower CD4+ T-cell counts are associated with increased rates of VVC, and VVC is associated with increased viral shedding. Treatment measures in women with HIV infection are identical to those women without HIV infection.

There has been significant new knowledge generated about VVC since the 2015 CDC Guidelines which have led to changing recommendations.

The evidence reviewed mostly focused on efficacy of doxycycline and azithromycin for urogenital, rectal, and oropharyngeal CT infection, CT risk factors in women, performance of CT nucleic acid amplification tests on self-collected meatal specimens in men, and performance of newer CT point-of-care tests.
Mucosal initiated immune responses may be involved in the pathophysiology of rheumatoid arthritis (RA). The most abundant immunoglobulin at mucosal surfaces is IgA, of which two subclasses exist IgA1 and IgA2. IgA2 is mainly present at mucosal sites and has been ascribed pro-inflammatory properties. As IgA subclasses might provide insights into mucosal involvement and pro-inflammatory mechanisms, we investigated IgA responses in sera of RA patients.

In two cohorts of RA patients, the EAC and IMPROVED, total IgA1 and IgA2 were measured by ELISA. Furthermore, IgA subclass levels of rheumatoid factor (RF) and anti-citrullinated protein antibodies (anti-CCP2) were determined. The association of these IgA subclass levels with CRP and smoking was investigated.

Total IgA1 and IgA2 were increased in RA patients compared with healthy donors in both cohorts. This increase was more pronounced in seropositive RA vs seronegative RA. For RF and anti-CCP2, both IgA1 and IgA2 could be detected. No strong associations were found between IgA subclasses (total, RF and anti-CCP2) and CRP. In smoking RA patients, a trend towards a selective increase in total IgA2 and RF IgA1 and IgA2 was observed.

RA patients have raised IgA1 and IgA2 levels. No shift towards IgA2 was observed, indicating that the increase in total IgA is not due to translocation of mucosal IgA into the bloodstream. However, mucosal inflammation might play are role, given the association between smoking and total IgA2 levels. Despite its pro-inflammatory properties, IgA2 does not associate strongly with pro-inflammatory markers in RA patients.

This study intends to appraise the feasibility of double sleeve lobectomy after neoadjuvant chemotherapy in central non-small-cell lung cancer with bronchovascular aggression.

This retrospective study included non-small-cell lung cancer patients who received double sleeve lobectomy from January 2014 to June 2020. Patients were divided into 2 groups the neoadjuvant chemotherapy group and the non-neoadjuvant chemotherapy group. Demographic data and perioperative outcomes were compared between these 2 groups.

Of the 110 patients who received double sleeve lobectomy during this period, 35 patients (31.8%) received neoadjuvant chemotherapy. Compared with the non-neoadjuvant chemotherapy group, patients who received neoadjuvant chemotherapy were associated with younger age (P = 0.026), smaller pathologic tumour size (P = 0.005), higher forced expiratory volume in 1 s (P = 0.007), higher forced expiratory volume in 1 s of predicted value (P = 0.005) and higher clinical stage (P < 0.001). In the neoadjuvant al lung cancer involving both the pulmonary artery and bronchus.
Sabizabulin, an oral cytoskeleton disruptor, was tested in a phase Ib/II clinical study in men with metastatic castration-resistant prostate cancer (mCRPC).

The phase Ib portion utilized a 3+3 design with escalating daily oral doses of 4.5-81 mg and increasing schedule in 39 patients with mCRPC treated with one or more androgen receptor-targeting agents. Prior taxane chemotherapy was allowed. The phase II portion tested a daily dose of 63 mg in 41 patients with no prior chemotherapy. Efficacy was assessed using PCWG3 and RECIST 1.1 criteria.

The MTD was not defined in the phase Ib and the recommended phase II dose was set at 63 mg/day. The most common adverse events (>10% frequency) at the 63 mg oral daily dosing (combined phase Ib/II data) were predominantly grade 1-2 events. Grade ≥3 events included diarrhea (7.4%), fatigue (5.6%), and alanine aminotransferase/aspartate aminotransferase elevations (5.6% and 3.7%, respectively). Neurotoxicity and neutropenia were not observed. Preliminary efficacy data in patients treated with ≥1 continuous cycle of 63 mg or higher included objective response rate in 6 of 29 (20.
