There is therapeutic uncertainty regarding use of combination or single-agent chemotherapy in the treatment of patients with gallbladder cancer who experience disease progression after first-line chemotherapy.

To compare the efficacy of capecitabine plus irinotecan (CAPIRI) vs irinotecan (IRI) alone in patients with advanced gallbladder cancer (GBC) who have disease progression after gemcitabine-based first-line treatment.

The GB-SELECT trial was a multicenter, open-label, phase 2, randomized clinical trial of CAPIRI vs IRI alone for treatment of gallbladder cancer in patients who had disease progression after prior gemcitabine-based chemotherapy.The study was carried out in 2 tertiary care institutions in India. Patients aged between 18 and 70 years with histopathologic diagnosis of adenocarcinoma gallbladder, advanced or metastatic disease, previous treatment with gemcitabine-based chemotherapy, adequate hematologic, liver, and renal functions, and ECOG performance status of 1 or less were included inuired dose modification in CAPIRI compared with the IRI arm (13 [27%] vs 4 [9%], respectively, P = .03).

There was no significant difference in OS between treatment with capecitabine plus irinotecan or irinotecan alone among previously treated patients with gallbladder cancer. Single-agent irinotecan should be the preferred treatment option for such patients.

Asthma is a major public health problem worldwide and is associated with excess morbidity, mortality, and economic costs associated with lost productivity. The National Asthma Education and Prevention Program has released the 2020 Asthma Guideline Update with updated evidence-based recommendations for treatment of patients with asthma.

To report updated recommendations for 6 topics for clinical management of adolescents and adults with asthma (1) intermittent inhaled corticosteroids (ICSs); (2) add-on long-acting muscarinic antagonists; (3) fractional exhaled nitric oxide; (4) indoor allergen mitigation; (5) immunotherapy; and (6) bronchial thermoplasty.

The National Heart, Lung, and Blood Advisory Council chose 6 topics to update the 2007 asthma guidelines based on results from a 2014 needs assessment. The Agency for Healthcare Research and Quality conducted systematic reviews of these 6 topics based on literature searches up to March-April 2017. Reviews were updated through October 2018 and used by anpart of an ongoing research effort.

Asthma is a common disease with substantial human and economic costs globally. Although there is no cure or established means of prevention, effective treatment is available. Use of the recommendations in the 2020 Asthma Guideline Update should improve the health of individuals with asthma.

We investigated the expression level, prognostic value, and potential function of PPPs with data from Oncomine, GEPIA, THPA, and TCGA databases and an independent cohort of patients with pancreatic cancer. Among all the PPP catalytic subunits (PPPcs), the transcription levels of PPP1CA, PPP1CB, PPP3CA, PPP3CB, and PPP4C were higher in pancreatic cancer than in normal pancreas (P 2). Kaplan-Meier analysis showed that high transcription levels of PPP1CA, PPP1CB, PPP2CA, PPP2CB, PPP3CA, and PPP4C correlated with poorer survival. In contrast, patients with high levels of PPP3CB, PPP3CC, PPP5C, PPP6C, and PPEF2 had much better prognoses. Data from THPA and patients with pancreatic cancer enrolled in our hospital also confirmed the prognostic value of PPP1CA, PPP1CB, PPP2CA, PPP2CB, PPP3CA, PPP3CB, and PPP6C at the protein level. In addition, the Pearson Chi-square test showed that PPP3CB level was significantly correlated with T and N stages. GO and KEGG analyses showed that the genes and pathways related to the pathogenesis and progression of pancreatic cancer were greatly affected by alterations in PPPcs. Results of the present study suggest that PPP1CA, PPP1CB, PPP2CA, PPP2CB, and PPP3CA have deleterious effects but PPP3CB, PPP5C, and PPP6C have beneficial effects on pancreatic cancer.Age-related hearing loss (ARHL) is a common condition in humans marking the gradual decrease in hearing with age. learn more Perturbations in the tip-link protein cadherin-23 that absorbs the mechanical tension from sound and maintains the integrity of hearing is associated with ARHL. Here, in search of molecular origins for ARHL, we dissect the conformational behavior of cadherin-23 along with the mutant S47P that progresses the hearing loss drastically. Using an array of experimental and computational approaches, we highlight a lower thermodynamic stability, significant weakening in the hydrogen-bond network and inter-residue correlations among β-strands, due to the S47P mutation. The loss in correlated motions translates to not only a remarkable two orders of magnitude slower folding in the mutant but also to a proportionately complex unfolding mechanism. We thus propose that loss in correlated motions within cadherin-23 with aging may trigger ARHL, a molecular feature that likely holds true for other disease-mutations in β-strand-rich proteins.

Blood-brain barrier disruption (BBBD) is a systemic therapy for malignant central nervous system (CNS) tumors that has been linked to poorly understood pigmentary maculopathy.

To examine the rate of and risk factors for the development of BBBD-associated maculopathy and to assess whether there can be visually significant progression after completion of systemic therapy.

In this retrospective case series, data from February 1, 2006, through December 31, 2019, were collected from patients treated with osmotic BBBD at a single tertiary referral center who had subsequent ophthalmic evaluation.

Treatment with BBBD therapy for any malignant CNS tumor.

Rate and potential risk factors for developing BBBD-associated maculopathy and changes in visual acuity and retinal imaging characteristics after completion of BBBD therapy.

Of 283 patients treated with BBBD and chemotherapy for a CNS malignant neoplasm, 68 (mean [SD] age, 46.0 [17.9] years; 25 [38.5%] female) had an ophthalmic examination after starting systemic therapy.
