Comment Randomized Controlled Trial Multicenter Study
Bisoprolol in Patients With Chronic Obstructive Pulmonary Disease at High Risk of Exacerbation: The BICS Randomized Clinical Trial.
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Observational studies report that β-blocker use may be associated with reduced risk of COPD exacerbations. However, a recent trial reported that metoprolol did not reduce COPD exacerbations and increased COPD exacerbations requiring hospital admission. ⋯ Among people with COPD at high risk of exacerbation, treatment with bisoprolol did not reduce the number of self-reported COPD exacerbations requiring treatment with oral corticosteroids, antibiotics, or both.

Spinal cord stimulation (SCS) is an effective modality for pain treatment, yet its underlying mechanisms remain elusive. Neurokinin 1 receptor-positive (NK1R+) neurons in spinal lamina I play a pivotal role in pain transmission. To enhance our mechanistic understanding of SCS-induced analgesia, we investigated how different SCS paradigms modulate the activation of NK1R+ neurons, by developing NK1R-Cre;GCaMP6s transgenic mice and using in vivo calcium imaging of superficial NK1R+ neurons under anesthesia (1.5% isoflurane). ⋯ However, at low intensity (20% MoT), the 30-minute 900-Hz SCS only induced persistent neuronal inhibition in naïve mice, but not in SNI-t mice. In conclusion, both 10-minute high-intensity SCS and 30-minute SCS at moderate intensity inhibit the activation of superficial NK1R+ neurons, potentially attenuating spinal nociceptive transmission. Furthermore, in vivo calcium imaging of NK1R+ neurons provides a new approach for exploring the spinal neuronal mechanisms of pain inhibition by neuromodulation pain therapies.

Meta-analytic findings and clinical practice guidance recommend pharmacological (e.g., pregabalin, duloxetine, and milnacipran) and non-pharmacological (e.g., exercise and sleep hygiene) interventions to reduce symptoms and improve quality of life in people living with fibromyalgia. However, some of these therapies may lack robust evidence as to their efficacy, have side effects that may outweigh benefits, or carry risks. Although the annual prevalence of fibromyalgia in active duty service members was estimated to be 0.015% in 2018, the likelihood of receiving a fibromyalgia diagnosis was 9 times greater in patients assigned female than male and twice as common in non-Hispanic Black than White service members. Therefore, the primary goal of this retrospective study is to examine co-occurring conditions and pain-management care receipt in the 3 months before and 3 months after fibromyalgia diagnosis in active duty service members from 2015 to 2022. ⋯ Overall, service members diagnosed with fibromyalgia received variable guideline-congruent health care within the 3 months before and after fibromyalgia diagnosis. Almost 1 in 3 service members received an opioid prescription, which has been explicitly recommended against use in guidelines. Pairwise comparisons indicated unwarranted variation across assigned sex and race and ethnicity in both co-occurring health conditions and care receipt. Underlying reasons for health and health care inequities can be multisourced and modifiable. It is unclear whether the U.S. Military Health System has consolidated patient resources to support patients living with fibromyalgia and if so, the extent to which such resources are accessible and known to patients and their clinicians.

Randomized Controlled Trial Multicenter Study Comparative Study
Molecularly guided therapy versus chemotherapy after disease control in unfavourable cancer of unknown primary (CUPISCO): an open-label, randomised, phase 2 study.
Patients with unfavourable subset cancer of unknown primary (CUP) have a poor prognosis when treated with standard platinum-based chemotherapy. Whether first-line treatment guided by comprehensive genomic profiling (CGP) can improve outcomes is unknown. The CUPISCO trial was designed to inform a molecularly guided treatment strategy to improve outcomes over standard platinum-based chemotherapy in patients with newly diagnosed, unfavourable, non-squamous CUP. The aim of the trial was to compare the efficacy and safety of molecularly guided therapy (MGT) versus standard platinum-based chemotherapy in these patients. This was to determine whether the inclusion of CGP in the initial diagnostic work-up leads to improved outcomes over the current standard of care. We herein report the primary analysis. ⋯ F Hoffmann-La Roche.
