This review examines the use of novel US-guided nerve blocks in clinical practice. Erector spinae block is a regional anesthesia technique doing by injecting a local anesthetic among the erector ...spinae muscle group and transverse processes. The phrenic nerve is a branch of the cervical plexus, arising from the anterior rami of cervical nerves C3, C4, and C5. The quadratus lumborum muscle is located along the posterior abdominal wall. It originates from the transverse process of the L5 vertebral body, the iliolumbar ligament, and the iliac crest. US-guided peripheral nerve procedures have a considerable scope of use, including treating headaches and hiccups to abdominal surgical pain, cesarean sections, musculoskeletal pathologies. These nerve blocks have been an effective addition to clinical anesthesia practice. The use of peripheral nerve blocks has improved postoperative pain, lessened the use of opioids and their potential side effects, and decreased the incidence of sleep disturbance in patients. More research should be done to further delineate the potential benefits of these blocks.
Infertility, the inability to establish a clinical pregnancy after 12 months of regular unprotected sexual intercourse, is caused by a wide variety of both male and female factors. Infertility is ...estimated to affect between 8-12% of couples trying to conceive globally. Female factor infertility can be subdivided into the following broad categories: ovulatory dysfunction, fallopian tubal disease, uterine causes, and oocyte quality. Hyperprolactinemia causes ovulary dysfunction along with other hormonal abnormalities, such as decreased estrogen, which can lead to infertility. In this regard, antipsychotics are commonly used for both schizophrenia and bipolar disorder. The use of these medications can be associated with hyperprolactinemia and hyperprolactinemia associated infertility. Antipsychotic-induced hyperprolactinemia occurs through blockade of D
receptors on lactotroph cells of the anterior pituitary gland. Discontinuation of the hyperprolactinemia-inducing antipsychotic is an option, but this may worsen the patient's psychosis or mood. If antipsychotics are determined to be the culprit of infertility, the degree of hyperprolactinemia symptoms, length of treatment with the antipsychotic, and risk of relapse should be assessed prior to discontinuation, reduction, or switching of antipsychotic medications. The treatment of a women's mental health and her desire to have children should always be considered as treatment may influence fertility while on the medication.
Objective
This study was designed to determine whether intensive lifestyle intervention (ILI) aimed at weight loss lowers cancer incidence and mortality.
Methods
Data from the Look AHEAD trial were ...examined to investigate whether participants randomized to ILI designed for weight loss would have reduced overall cancer incidence, obesity‐related cancer incidence, and cancer mortality, as compared with the diabetes support and education (DSE) comparison group. This analysis included 4,859 participants without a cancer diagnosis at baseline except for nonmelanoma skin cancer.
Results
After a median follow‐up of 11 years, 684 participants (332 in ILI and 352 in DSE) were diagnosed with cancer. The incidence rates of obesity‐related cancers were 6.1 and 7.3 per 1,000 person‐years in ILI and DSE, respectively, with a hazard ratio (HR) of 0.84 (95% CI: 0.68‐1.04). There was no significant difference between the two groups in total cancer incidence (HR, 0.93; 95% CI: 0.80‐1.08), incidence of nonobesity‐related cancers (HR, 1.02; 95% CI: 0.83‐1.27), or total cancer mortality (HR, 0.92; 95% CI: 0.68‐1.25).
Conclusions
An ILI aimed at weight loss lowered incidence of obesity‐related cancers by 16% in adults with overweight or obesity and type 2 diabetes. The study sample size likely lacked power to determine effect sizes of this magnitude and smaller.
Complete revascularization of coronary artery disease has been linked to improved outcomes in patients with preserved left ventricular (LV) function.
This study sought to identify the impact of ...complete revascularization in patients with severe LV dysfunction.
Patients enrolled in the REVIVED-BCIS2 (Revascularization for Ischemic Ventricular Dysfunction) trial were eligible if baseline/procedural angiograms and viability studies were available for analysis by independent core laboratories. Anatomical and viability-guided completeness of revascularization were measured by the coronary and myocardial revascularization indices (RIcoro and RImyo), respectively, where RIcoro = (change in British Cardiovascular Intervention Society Jeopardy score BCIS-JS) / (baseline BCIS-JS) and RImyo= (number of revascularized viable segments) / (number of viable segments supplied by diseased vessels). The percutaneous coronary intervention (PCI) group was classified as having complete or incomplete revascularization by median RIcoro and RImyo. The primary outcome was death or hospitalization for heart failure.
Of 700 randomized patients, 670 were included. The baseline BCIS-JS and SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) scores were 8 (Q1-Q3: 6-10) and 22 (Q1-Q3: 15-29), respectively. In those patients assigned to PCI, median RIcoro and RImyo values were 67% and 85%, respectively. Compared with the group assigned to optimal medical therapy alone, there was no difference in the likelihood of the primary outcome in those patients receiving complete anatomical or viability-guided revascularization (HR: 0.90; 95% CI: 0.62-1.32; and HR: 0.95; 95% CI: 0.66-1.35, respectively). A sensitivity analysis by residual SYNTAX score showed no association with outcome.
In patients with severe LV dysfunction, neither complete anatomical nor viability-guided revascularization was associated with improved event-free survival compared with incomplete revascularization or treatment with medical therapy alone.

When working with children in participatory design activities ethical questions arise that are not always considered in a standard ethics review. This paper highlights five challenges around the ...ethics of the value of design and the ethics of the children's participation and presents a new tool, CHECk that deals with three of these challenges by virtue of two checklists that are designed to challenge researchers in CCI and HCI to critically consider the reasons for involving children in design projects and to examine how best to describe design activities in order that children can better consent to participate.
