Dear reader, here are the summaries of some of the latest papers from PubMed.

Breast Cancer: RCB classification predicts prognosis after neoadjuvant chemotherapy; adjuvant therapy may offer similar survival benefits to neoadjuvant in ER+/HER2- breast cancer. Neoadjuvant pembrolizumab does not affect ovarian reserve in young triple-negative breast cancer patients, and new therapeutics like CDK4/6 inhibitors improve prognosis. Genetic variations influence response to chemotherapeutic agents. Source 1 Source 2 Source 3

COVID-19 Aftereffects: Longer ICU stay and diabetes mellitus predict physical inactivity post-COVID-19 hospitalization. Severe, persistent fatigue remains a significant unresolved issue for adolescent COVID-19 survivors. Source 1 Source 2

Breast Cancer: The AKT-FOXO3-FOXM1 axis influences the efficacy of AKT inhibitors in ER+ breast cancer with PIK3CA mutations. Loss of FOXO3 mediates resistance to these inhibitors, while downregulating FOXM1 predicts response to treatment. Additionally, FOXO1 acts as a tumor suppressor by inhibiting cell proliferation and survival. Source 1 Source 2

Genetics: Genetic variants influence protein levels in newborns at high risk for Type 1 diabetes, suggesting potential drug targets. Computational methods can enhance the discovery of protein-disease relationships to improve early disease detection and personalized medicine. Source 1 Source 2

Prostate Cancer: BRD9 helps prostate cancer cells maintain redox balance under oxidative stress, enabling castration-resistant growth. Inhibiting BRD9 increases cell sensitivity to radiotherapy. Source 1

Health Technologies: DNA-based microcapsules enhance probiotic delivery for inflammatory bowel disease management. A silver-anchored polydopamine nanocomposite hydrogel combats periodontitis more effectively than conventional treatments. Injectable antimicrobial hydrogels fortified with tannic and citric acids improve wound treatment efficacy. Enhanced antibiofilm efficacy of silver nanoparticles is achieved while mitigating aggregation and toxicity issues. Understanding biofilm formation by pathogenic bacteria is crucial for preventing dental infections, highlighting innovative strategies like nanoparticles and smart hydrogels. A dual-functional hydrogel (F-QMS-OX) combines hemostatic and antibacterial properties for improved material performance. Magnetic hydrogel-based microrobots deliver targeted antibiotics to infected sites, enhancing treatment efficacy. Prophages in periodontitis-causing bacteria influence bacterial virulence, antibiotic resistance, and metabolism, impacting disease progression.

Bioelectronic Devices: A method enhances hydrogel-based devices' conductivity and biocompatibility for medical applications like wearable sensors. An ionogel is developed to reversibly bond with skin at body temperature, remaining conductive and stable underwater, ideal for bioelectric electrodes. Source 1 Source 2

Drug Treatment: Pazopanib's dose reductions and treatment interruptions due to toxicity are common in clinical practice. Advanced control technologies and automated drug delivery can positively correlate medication doses with clinical effects, potentially optimizing patient management and addressing the drug titration paradox. Source 1 Source 2

Fertility Preservation: Fertility-sparing surgery is safe for young women with early stage epithelial ovarian cancer, maintaining survival rates. Ovarian tissue cryopreservation is also feasible and safe in pediatric patients, offering new fertility preservation options. Source 1 Source 2

Mental Health Access: Black perinatal women encounter systemic barriers to mental health services, emphasizing the need for culturally responsive training and transparent communication. Digital mental health tools show promise in increasing access for young people from diverse backgrounds, though further research is required to ensure effectiveness across different populations. Source 1 Source 2

Stent Management: Transcatheter management can treat proximal stent migration in CoA stenting. Self-expandable metallic stents are effective as a bridge to surgery for malignant colorectal obstruction, though optimal surgical timing needs further investigation. Source 1 Source 2

Platelets: A specific CD36 variant causes platelet CD36 deficiency in Chinese donors, with analysis of its molecular basis and population distribution. HMGB1 levels in single-donor apheresis platelet concentrates are influenced by donor characteristics including age, sex, and ABO blood group. Source 1 Source 2

Opioid Use Disorder: Providing medications in jails reduces post-release overdose risk. There is insufficient evidence for the safety of opioid tapering practices. Source 1 Source 2

Kidney Nephropathy: Endothelin receptor antagonists may be effective in treating non-diabetic kidney nephropathy, but further clinical data is required for confirmation. Clinicians should continue using beneficial medications like renin-angiotensin-aldosterone system inhibitors and sodium-glucose co-transporter 2 inhibitors during kidney conditions based on evidence-based patient-specific judgment rather than categorizing them as universally nephrotoxic. Source 1 Source 2

Sexual Health: Nurse-led psycho-educational interventions reduce uncertainty and anxiety in gynecological cancer patients. Timely diagnosis and individualized multidisciplinary treatment are crucial for managing midlife sexual health issues. Sexual counseling using the BETTER model improves sexual function in postmenopausal women. Tailored interventions enhance the quality of sexual life for postmenopausal women. Social media listening provides insights into menopausal women's experiences, symptoms, and treatment preferences. Source 1 Source 2 Source 3 Source 4 Source 5

Urothelial Carcinoma Treatment: Endoscopic ablation for localized, non-invasive upper urinary tract urothelial carcinoma with tumor size <2 cm results in similar cancer-specific mortality rates compared to radical nephroureterectomy. Additionally, recurrent renal clear cell carcinoma can develop in the ureteric stump years after radical nephrectomy, highlighting the importance of long-term surveillance and resection for curative intent upon recurrence detection. Source 1 Source 2

Lymphoma: The economic and healthcare burden of relapsed or refractory follicular lymphoma is significant, emphasizing the need for effective interventions. Reasonable survival rates for children with Burkitt lymphoma can be achieved in resource-limited settings through optimized use of resources like single-dose rasburicase and modified methotrexate dosing. Source 1 Source 2

Osteoporosis: A 6% increase in reporting of moderate/severe vertebral fragility fractures could prevent 890 hip fractures annually and save £13.2 million. There is a lack of sufficient data on managing osteoporosis in spinal cord injury patients. Socioeconomically disadvantaged populations experience higher rates of secondary fractures despite similar osteoporosis treatment rates, highlighting the need for targeted interventions. Source 1 Source 2 Source 3

Bone Health: OsteoSight™ technology accurately identifies patients at risk for low bone mineral density from X-rays. Lower BMD is associated with higher all-cause mortality in osteoarthritis patients. Pericoronary adipose tissue attenuation can predict abnormal bone mass, offering a new biomarker for bone health assessment. Source 1 Source 2 Source 3
