Sarcoid-like granulomatosis is a known but rare adverse reaction to immune checkpoint inhibitors and chemotherapy in the treatment of advanced solid tumors. We present a case of a 29-year-old female with a pathologically confirmed poorly differentiated invasive ductal carcinoma of the breast with presumed metastases to the lungs, hilar lymph nodes, liver, and spleen. Despite appropriate chemotherapy, the patient developed pulmonary lesions that were interpreted on imaging studies as progression of malignancy. Autopsy revealed disseminated sarcoid-like granulomatosis with multiple noncaseating granulomata with associated fibrosis in the lungs, liver, and spleen. No residual invasive carcinoma or metastatic disease was identified. This case illustrates the difficulty in differentiating this nonneoplastic process from progressive disease in the clinical setting.Introduction Immunotherapy has been introduced as a modern alternative for the treatment of various cancers, including the stimulation of the immune system by introduction of immunostimulatory molecules. Application of viral and non-viral vectors have provided a substantial contribution to improved delivery and expression of these immunostimulators.Areas covered Alphavirus vectors, based on Semliki Forest virus, have allowed immunization with self-replicating RNA, recombinant virus particles, and layered DNA/RNA vectors. The attractive features of alphaviruses comprise their broad host range and extreme RNA replication in infected cells resulting in very high recombinant protein expression levels providing enhanced immune responses and an excellent basis for immunotherapy.Expert opinion Immunization studies in animal tumor models have elicited strong humoral and cellular immune response, have provided prophylactic protection against tumor challenges, and have generated therapeutic efficacy in tumor-bearing animals. Clinical trials have indicated safe use of alphavirus vectors, making them attractive for cancer immunotherapy.Introduction Monogenic diabetes is a subset of diabetes characterized by the presence of single-gene mutations and includes neonatal diabetes mellitus and maturity-onset diabetes of the young. Due to the genetic etiology of monogenic diabetes, molecular genetic testing can be used for diagnosis and classification.Areas covered In addition to first-generation molecular analyses, many large clinical laboratories are transitioning to multiplexed next-generation sequencing panels to simultaneously assess patients for several of the most common genetic mutations seen in monogenic diabetes. With expanded development and adoption of next-generation sequencing panels, particularly in reference to laboratory settings, diagnostic testing for monogenic diabetes has the potential to be more accessible to the patient population.Expert opinion Although molecular diagnostic testing is becoming increasingly prevalent, it is crucial to identify patients most likely to benefit from molecular testing versus those whose disease can be diagnosed and characterized with more traditional, less costly laboratory analyses. The continuous evolution of clinical molecular testing will be echoed in the clinical laboratory analysis of monogenic diabetes and continue to improve the diagnostic capabilities for monogenic diabetes mellitus.Introduction Osteoporosis is a chronic, skeletal disorder characterized by compromised bone strength and increased fracture risk; it affects 50% of women and 20% of men. In the past two decades, there have been substantial improvements in the pharmacotherapy of osteoporosis which have yielded potent inhibitors of bone resorption or stimulators of bone formation.Areas covered This review discusses newly identified targets and pathways and conceptual approaches to the prevention of multiple age-related disorders. Furthermore, it summarizes existing therapeutic strategies for osteoporosis.Expert opinion Our enhanced understanding of bone biology and the reciprocal interactions between bone and other tissues have allowed the identification of new targets that may facilitate the development of novel drugs. These drugs will hopefully achieve the uncoupling of bone formation from resorption and possibly exert a dual anabolic and antiresorptive effect on bone. Alas, limitations regarding adherence, efficacy on nonvertebral fracture prevention and the long-term adverse events still exist for currently available therapeutics. Moreover, the efficacy of most agents is limited by the tight coupling of osteoblasts and osteoclasts; hence the reduction of bone resorption invariably reduces bone formation, and vice versa. This field is very much 'a work in progress.'There are many calls for increased rigor in interprofessional research, and scale validation improvements are particularly needed. Specifically, current validation efforts are limited, as few interprofessional scale development studies report evidence of convergent and discriminant validity. These are core aspects of establishing nomological networks and construct validity, and thus form the foundation of interprofessional theory, research, and practice. This paper focuses on the importance of construct validation for interprofessional measurement tools, reviewing key concepts, extant scales and their validation efforts, and providing recommendations for future interprofessional scale validation. We also provide a step-by-step guide for scale development and validation that we hope will be valuable for future researchers and scale developers in the interprofessional literature.Objective Asthma is frequently associated with chronic rhinosinusitis with nasal polyps (CRSwNP). Although endoscopic sinus surgery (ESS) improves asthma control in CRSwNP patients with asthma, the mechanism that underlies the response to surgical treatment is still unclear. Simufilam We evaluated the relevance of changes in asthma control and changes in airway/systemic inflammation in eosinophilic CRSwNP patients with not well controlled asthma who underwent ESS.Methods We prospectively assessed changes in the asthma control questionnaire (ACQ) score, blood eosinophil counts (B-Eos), forced expiratory volume in 1 s (FEV1), and fraction of exhaled nitric oxide (FeNO) levels at 1-week before and 8 and 52 weeks after ESS.Results Twenty-five subjects were analyzed. The ACQ score, B-Eos, and FeNO decreased, and FEV1 increased significantly after ESS. In the period from baseline to 52 weeks after ESS, changes in ACQ were significantly correlated with the changes in blood eosinophil counts (r = 0.58, p less then .01) and FeNO (r = 0.
