Background: People living with non-communicable diseases (NCDs) such as hypertension and diabetes are at high risk for mental health and psychosocial problems. These problems, in turn, can lead to social isolation, lower quality of life, greater health needs, and poorer health outcomes. The prevalence of NCDs is rising in humanitarian settings, where residents are already at an increased risk of mental health problems due to trauma and stressful living conditions.

Article Synopsis
  • This study evaluated the effectiveness of racemic ketamine intravenous treatments (KIT) for patients with treatment-resistant depression (TRD) compared to standard medication management (MM) in a health care system from 2018 to 2022.
  • Results showed that the KIT group had a greater likelihood of significant symptom improvement, with a 72% higher risk of achieving a more than 50% reduction in depression symptoms than the MM group.
  • The findings suggest that KIT might be a more effective option for treating TRD, but clinicians should consider factors like co-occurring mental health disorders and baseline symptom severity when predicting treatment responses.

We developed and evaluated the Digital Platform for Exercise (DPEx): a decentralized, patient-centric approach designed to enhance all aspects of clinical investigation of exercise therapy. DPEx integrated provision of a treadmill with telemedicine and remote biospecimen collection permitting all study procedures to be conducted in patient's homes. Linked health biodevices enabled high-resolution monitoring of lifestyle and physiological response.

Article Synopsis
  • Sick sinus syndrome (SSS) can lead to serious health issues like fainting and the need for pacemakers, and researchers wanted to see if atrial flutter (AFL) could predict SSS better than other factors.
  • The study analyzed data from over 29 million adults in California from 2005 to 2019, focusing on those diagnosed with AFL and atrial fibrillation (AF) while adjusting for various demographics.
  • Results showed that both AFL and AF significantly increased the risk of developing SSS, with AFL notably heightening the risks of syncope and needing a pacemaker in patients already diagnosed with AF.

Background And Purpose: Posterior circulation strokes, accounting for 20% of acute ischemic strokes, significantly contribute to morbidity and mortality. Fibrinolysis by rtPA improves outcomes in stroke but the risk of intracranial hemorrhage limits benefit. Arterial recanalization of basilar artery occlusion by thrombolysis or endovascular thrombectomy improves outcomes in posterior circulation strokes.

Objective: To compare the risk of hospitalization for infection among patients who achieve intensive versus relaxed glycemic control.

Research Design And Methods: This retrospective cohort study included adults age ≥65 years with type 2 diabetes from an integrated health care delivery system. Negative binomial models were used to estimate incidence rates and relative risk (RR) of hospitalization for infections (respiratory; genitourinary; skin, soft tissue, and bone; and sepsis), comparing two levels of relaxed (hemoglobin A1c [HbA1c] 7% to <8% and 8% to <9%) with intensive (HbA1c 6% to <7%) glycemic control from 1 January 2019 to 1 March 2020.

Article Synopsis
  • - Bronchiolitis obliterans syndrome (BOS) is a serious lung condition that can develop after receiving a stem cell transplant, and this study tested the effectiveness of ruxolitinib in treating it.
  • - The trial involved 49 adult participants divided into two groups based on how recently they were diagnosed with BOS; results showed that 27.8% of newly diagnosed patients improved, while 92.3% of those with established BOS maintained stable lung function after treatment.
  • - Overall, ruxolitinib had a lung-specific response rate of 34.7% among all participants with most positive outcomes seen in patients with mild to moderate disease, indicating it could be a beneficial treatment option for BOS

In low- and middle-income countries (LMICs), children and families face a multitude of risk factors for mental health and well-being. These risks are even further exacerbated in humanitarian emergencies. However, access to effective mental health services in such settings is severely limited, leading to a large mental health treatment gap.

Background: Whether structured exercise therapy improves chemotherapy delivery, tolerability, and tumor response is unclear.

Methods: This was a secondary analysis of a phase 2 trial investigating exercise therapy (n = 72) versus usual care (n = 72) in patients with primary breast cancer. Exercise therapy comprised individualized treadmill walking three times weekly for 20-50 minutes per session at 55%-100% of pretreatment exercise capacity.

Comprehensive survivorship care after hematopoietic cell transplantation (HCT) includes revaccination to restore immunity to vaccine-preventable diseases (VPDs). There is complexity to revaccination in this setting, and revaccination rates are sub-optimal. HCT survivors are at high-risk for morbidity and mortality from infections including VPDs, underscoring the importance of interventions to improve revaccination rates among survivors.

Article Synopsis
  • Hypertension is a significant risk factor for dementia, and the study aims to determine if poorly managed hypertension increases dementia risk in individuals with HIV.
  • The researchers analyzed data from over 69,000 participants (including nearly 3,100 with HIV), evaluating their blood pressure control against dementia risk over several years using a disease management index (DMI).
  • Results indicated that inadequate control of both systolic and diastolic blood pressure was linked to a higher risk of developing dementia, regardless of HIV status, with diastolic pressure control showing particularly strong associations.

We examined clinically node-positive (cN+) breast cancer patients undergoing neoadjuvant chemotherapy and clipped lymph node (CLN) localization to determine the rate of CLN = non-sentinel lymph node (SLN), the factors associated with cN+ to pN0 conversion, and the treatment impact. We conducted a single institution review of cN+ patients receiving NAC from 2016 to 2022 with preoperative CLN localization (N = 81). Demographics, hormone receptor (HR) and HER2 status, time to surgery, staging, chemotherapy regimen, localization method, pathology, and adjuvant therapy were analyzed.

Since 2005, there has been a steady decline in chronic graft-versus-host disease (cGVHD) at the Fred Hutchinson Cancer Center. To better understand this phenomenon, we studied the risk of cGVHD requiring systemic immunosuppression (cGVHD-IS) as a function of hematopoietic cell transplantation (HCT) date in 3066 survivors from 2005 through 2019. Cox regression models were fit to assess associations of HCT date (as a continuous linear variable) with cause-specific hazards of cGVHD using unadjusted and adjusted models.

Importance: Levying excise taxes on sugar-sweetened beverage (SSB) distributors, which are subsequently passed on to consumers, is a policy implemented to reduce the high prevalence of cardiometabolic disease and generate public health funding. Taxes are associated with lower SSB purchases and consumption, but it is unknown whether they are associated with weight-related outcomes in youth.

Objective: To determine the association of SSB excise taxes with youth body mass index (BMI) trajectories.
