Clinical Update in Heart Failure with Preserved Ejection Fraction.

To review the most recent clinical trials and data regarding epidemiology, pathophysiology, diagnosis, and treatment of heart failure with preserved ejection fraction with an emphasis on the recent trends in cardiometabolic interventions. Heart failure with preserved ejection fraction makes up approximately half of overall heart failure and is associated with significant morbidity, mortality, and overall burden on the healthcare system. It is a complex, heterogenous syndrome and clinical trials, to this point, have not revealed quite as many effective treatment options when compared to heart failure with reduced ejection fraction. Nevertheless, there is an expanding amount of data insight into the pathogenesis of this disease and the potential for newer therapies and management strategies. Heart failure with preserved ejection fraction pathology has been found to be linked to abnormal energetics, myocyte hypertrophy, cell signaling, inflammation, ischemia, and fibrosis. These mechanisms also intricately overlap with the significant comorbidities often associated with heart failure with preserved ejection fraction including, but not limited to, atrial fibrillation, chronic kidney disease, hypertension, obesity and coronary artery disease. Treatment of this disease, therefore, should focus on the management and strict regulation of these comorbidities by pharmacologic and nonpharmacologic means. In this review, a clinical update is provided reviewing the most recent clinical trials and data regarding epidemiology, pathophysiology, diagnosis, and treatment of heart failure with preserved ejection fraction with an emphasis on the recent trend in cardiometabolic interventions.

Postnatal care of women with diabetes: a clinical update

Diabetes mellitus and gestational diabetes mellitus significantly affect pregnant women, their fetuses and neonates. Midwives need to be aware of their vital role in the care of women with diabetes and keep up to date with the latest evidence and guidelines. However, midwives have reported a deficit in their knowledge regarding postnatal care of women with diabetes. In this article, the challenges of maternity care for women with diabetes are highlighted, and the specific midwifery role in some aspects of postnatal care is discussed. The provision of woman-centred care by midwives, together with the expert knowledge of the diabetic team, can reduce postnatal diabetic complications.

Respiratory issues and current management in neuromuscular diseases: a narrative review.

Respiratory care is often embedded as a component of the overlapping management strategies in many patients with neuromuscular disease (NMD). Implementation of respiratory care strategies requires a sensitivity to the nature of the disease, the vulnerability during rapid eye movement (REM) sleep and complicating comorbidities specific to each patient. Care must adjust to progression of the disease as well as the comfort and preferences of the patient. Clinical presentations are usually heterogenous based on the specific NMD and overall course of the disease making diagnosis and respiratory care challenging. The aim of this review was to review the state-of-the-art evidence-based clinical practices and updates in the management of respiratory complications in patients with NMDs. We conducted a search on the PubMed and Medline databases using these keywords: secretions, neuromuscular disease, neuromuscular disorders, non-invasive ventilator, neuromuscular respiratory weakness, respiratory failure. The specified timeframe began from 1980 to 2024. Timely use of non-invasive ventilation and overall respiratory care is most important as emerging evidence shows some benefits with improved mortality in this group of patients. In some settings, comorbid complications that dictate need for airway management and oral diversion may have a more profound impact on mortality than the effectiveness of ventilatory support that are chosen. A multidisciplinary team approach to care has been shown to improve the quality of life and survival in these patients in centers of excellence. Patients should have the ability to access services provided by neurology, pulmonology, speech pathology, sleep medicine, cardiology and respiratory therapy services. The cornerstone for management of respiratory failure and sleep disordered breathing in NMD is non-invasive ventilation (NIV). Initiation of this support and other respiratory cares need to be timely, and patients may have very subtle symptoms during the early stages of the disease which makes it challenging in recognizing the onset of respiratory muscle stress and fatigue. Close attention to these symptoms as well as respiratory and radiologic parameters is essential for appropriate incorporation of these cares.

We review the high-impact publications of the year 2023 up to April 2024, which provide great insight into clinical, biomarker, imaging, pathogenetic, and therapeutic updates.

Strategic Developments in Polymer-Functionalized Liposomes for Targeted Colon Cancer Therapy: An Updated Review of Clinical Trial Data and Future Horizons.

Liposomes, made up of phospholipid bilayers, are efficient nanocarriers for drug delivery because they can encapsulate both hydrophilic and lipophilic drugs. Conventional cancer treatments sometimes involve considerable toxicities and adverse drug reactions (ADRs), which limits their clinical value. Despite liposomes' promise in addressing these concerns, clinical trials have revealed significant limitations, including stability, targeted distribution, and scaling challenges. Recent clinical trials have focused on enhancing liposome formulations to increase therapeutic efficacy while minimizing negative effects. Notably, the approval of liposomal medications like Doxil demonstrates their potential in cancer treatment. However, the intricacy of liposome preparation and the requirement for comprehensive regulatory approval remain substantial impediments. Current clinical trial updates show continued efforts to improve liposome stability, targeting mechanisms, and payload capacity in order to address these issues. The future of liposomal drug delivery in cancer therapy depends on addressing these challenges in order to provide patients with more effective and safer treatment alternatives.

Durability of Response With Selpercatinib in Patients With RET-Activated Thyroid Cancer: Long-Term Safety and Efficacy From LIBRETTO-001.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.LIBRETTO-001 is a registrational phase I/II, single-arm, open-label study of selpercatinib in patients with RET (REarranged during Transfection)-activated cancers (ClinicalTrials.gov identifier: NCT03157128). We present long-term safety and efficacy from LIBRETTO-001 in patients with RET-mutant medullary thyroid cancer (MTC; n = 324) and RET fusion-positive thyroid cancer encompassing different histological subtypes (TC; n = 66). At the data cutoff of January 2023, the objective response rate was 82.5% among patients with cabozantinib/vandetanib-naïve MTC and 95.8% among patients with treatment-naïve TC. At a median follow-up time of 42.4 and 44.0 months in patients with cabozantinib/vandetanib-naïve and pretreated MTC, the median progression-free survival (PFS) was not reached and 41.4 months, respectively. At a median follow-up time of 24.9 and 30.4 months in patients with treatment-naïve and pretreated TC, the median PFS was not reached and 27.4 months, respectively. Three-year PFS rates were 75.2% and 87.3% among patients with cabozantinib/vandetanib-naïve MTC and treatment-naïve TC, respectively. Median PFS was similar to median duration of response for each patient group. The safety profile of selpercatinib was consistent with previous reports. With an additional follow-up of 37 months and 228 more patients from the last disclosure, selpercatinib continued to provide durable and robust responses in treatment-naïve and previously treated patients with RET-mutant MTC and RET fusion-positive TC.

Historical Perspectives and Clinical Updates on Preterm Bottle Feeding With Noninvasive Ventilation.

The controversial topic of oral feeding while on noninvasive ventilation remains at the forefront of preterm intensive care management. The intersection of pulmonary, neurologic, and gastrointestinal maturation coalesces at a postmenstrual age that requires changes in practices compared with those used in older infants. Various animal models in the past decades aimed to gain physiological knowledge of noninvasive ventilation effects on the suck-swallow-breathe coordination sequence. However, the preterm infant poses nuanced anatomic challenges. Although concerns for oral feeding while on noninvasive ventilation include aspiration risks and potential inpatient obstacles, there is evidence to support the feasibility, initiation, and progression of oral feedings while an infant is supported on high-flow nasal cannula and continuous positive airway pressure. There is evidence to support that this may accelerate attainment of oral feeding milestones and, thus, eventual hospital discharge. More recent multidisciplinary institutional protocols may provide cautious guidance on evaluation and algorithms to assess infants who may benefit from initiation and advancement of oral feeding versus awaiting further maturation.

The Interdisciplinary Management of Tooth Agenesis; Clinical Update

The term hypodontia is used when one to six teeth, excluding third molars, are missing, and oligodontia when more than six teeth are absent (excluding the third molars). The long‐term management of hypodontia in the aesthetic zone is a particularly challenging situation. Although there are essentially two distinct approaches to manage this problem, that is space closure or opening for prosthetic replacements, implant or autotransplantation. Management of tooth agenesis can be realized by either closing or opening the spaces of congenitally missing teeth and by correction of dentoskeletal problems with orthodontic mechanics. Restorative dentistry procedures accompany orthodontic treatment when filling the spaces of missing teeth or when reshaping the teeth substituting missing teeth. As a conclusion, treatment of problems related with mild or severe tooth agenesis requires multidisciplinary treatment approaches. The purpose of this review article is to examine the etiology, clinical properties and treatment alternatives of tooth agenesis.

Results of the Simultaneous Combination of Ponatinib and Blinatumomab in Philadelphia Chromosome-Positive ALL.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.In this analysis, we update our experience with the chemotherapy-free regimen of blinatumomab and ponatinib in 60 patients with newly diagnosed Philadelphia chromosome (Ph)-positive ALL. At a median follow-up of 24 months, the complete molecular response rate by reverse transcriptase-polymerase chain reaction was 83% (67% at the end of course one), and the rate of measurable residual disease negativity by next-generation clono-sequencing was 98% (45% at the end of course one). Only two patients underwent hematopoietic stem cell transplantation (HSCT). Seven patients relapsed: two with systemic disease, four with isolated CNS relapse, and one with extramedullary Ph-negative, CRLF2-positive pre-B ALL. The estimated 3-year overall survival rate was 91% and event-free survival rate was 77%. Three patients discontinued blinatumomab because of adverse events (related, n = 1; unrelated, n = 2) and nine discontinued ponatinib because of cerebrovascular ischemia, coronary artery stenosis, persistent rash, elevated liver function tests with drug-induced fatty liver, atrial thrombus, severe arterial occlusive disease of lower extremities, pleuro-pericardial effusion, and debilitation. In conclusion, the simultaneous combination of ponatinib and blinatumomab is a highly effective and relatively safe nonchemotherapy regimen. This regimen also reduces the need for intensive chemotherapy and HSCT in first remission in the majority of patients.

Clinical Updates and Surveillance Recommendations for DNA Replication Repair Deficiency Syndromes in Children and Young Adults.

Replication repair deficiency (RRD) is a pan-cancer mechanism characterized by abnormalities in the DNA mismatch repair (MMR) system due to pathogenic variants in the PMS2, MSH6, MSH2, or MLH1 genes, and/or in the polymerase-proofreading genes POLE and POLD1. RRD predisposition syndromes (constitutional MMR deficiency, Lynch, and polymerase proofreading-associated polyposis) share overlapping phenotypic and biological characteristics. Moreover, cancers stemming from germline defects of one mechanism can acquire somatic defects in another, leading to complete RRD. Here we describe the recent advances in the diagnostics, surveillance, and clinical management for children with RRD syndromes. For patients with constitutional MMR deficiency, new data combining clinical insights and cancer genomics have revealed genotype-phenotype associations and helped in the development of novel functional assays, diagnostic guidelines, and surveillance recommendations. Recognition of non-gastrointestinal/genitourinary malignancies, particularly aggressive brain tumors, in select children with Lynch and polymerase proofreading-associated polyposis syndromes harboring an RRD biology have led to new management considerations. Additionally, universal hypermutation and microsatellite instability have allowed immunotherapy to be a paradigm shift in the treatment of RRD cancers independent of their germline etiology. These advances have also stimulated a need for expert recommendations about genetic counseling for these patients and their families. Future collaborative work will focus on newer technologies such as quantitative measurement of circulating tumor DNA and functional genomics to tailor surveillance and clinical care, improving immune surveillance; develop prevention strategies; and deliver these novel discoveries to resource-limited settings to maximize benefits for patients globally.

Tailored Dose-Dense Versus Standard Adjuvant Chemotherapy for High-Risk Early Breast Cancer: End-of-Study Results of the Randomized PANTHER Trial.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.Although dose-dense adjuvant chemotherapy administered once every 2 weeks leads to superior outcomes compared with standard regimens once every 3 weeks, the observed improvement is largely limited to studies using the suboptimal paclitaxel schedule once every 3 weeks as control. PANTHER is an international phase III trial which compared sequential epirubicin/cyclophosphamide and docetaxel administered either once every 2 or once every 3 weeks, with tailored dosing at the dose-dense schedule according to hematologic toxicity. In this end-of-study analysis, the median follow-up was 10.3 years. Compared with standard adjuvant chemotherapy, dose-dense treatment improved breast cancer recurrence-free survival (hazard ratio [HR], 0.80 [95% CI, 0.65 to 0.98]; P = .030), event-free survival (HR, 0.78 [95% CI, 0.65 to 0.94]; P = .009), and distant disease-free survival (HR, 0.79 [95% CI, 0.64 to 0.98]; P = .030) while the improvement in overall survival was not statistically significant (HR, 0.82 [95% CI, 0.65 to 1.04]; P = .109). To our knowledge, this is the first trial that confirms the benefit of a dose-dense regimen over a control regimen containing docetaxel once every 3 weeks.

Implications of pregnancy on cardiometabolic disease risk: preeclampsia and gestational diabetes.

Cardiometabolic disorders, such as obesity, insulin resistance, and hypertension, prior to and within pregnancy are increasing in prevalence worldwide. Pregnancy-associated cardiometabolic disease poses a great risk to the short- and long-term well-being of the mother and offspring. Hypertensive pregnancy, notably preeclampsia, as well as gestational diabetes are the major diseases of pregnancy growing in prevalence as a result of growing cardiometabolic disease prevalence. The mechanisms whereby obesity, diabetes, and other comorbidities lead to preeclampsia and gestational diabetes are incompletely understood and continually evolving in the literature. In addition, novel therapeutic avenues are currently being explored in these patients to offset cardiometabolic-induced adverse pregnancy outcomes in preeclamptic and gestational diabetes pregnancies. In this review, we discuss the emerging pathophysiological mechanisms of preeclampsia and gestational diabetes in the context of cardiometabolic risk as well as the most recent preclinical and clinical updates in the pathogenesis and treatment of these conditions.

Neoadjuvant Docetaxel, Oxaliplatin, and S-1 Plus Surgery and Adjuvant S-1 for Resectable Advanced Gastric Cancer: Updated Overall Survival Outcomes From Phase III PRODIGY.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.The phase III PRODIGY study demonstrated that neoadjuvant chemotherapy with docetaxel, oxaliplatin, and S-1 (DOS) followed by surgery and adjuvant S-1 chemotherapy (CSC) improved progression-free survival (PFS) compared with surgery followed by adjuvant S-1 (SC) for patients with resectable locally advanced gastric cancer (LAGC) with clinical T2-3N+ or T4Nany disease. The primary end point was PFS. Overall survival (OS) was the secondary end point. We herein report the long-term follow-up outcomes, including OS, from this trial. A total of 238 and 246 patients were randomly assigned to the CSC and SC arms, respectively, and were treated (full analysis set). As of the data cutoff (September 2022), the median follow-up duration of the surviving patients was 99.5 months. Compared with SC, CSC significantly increased the OS (adjusted hazard ratio [HR], 0.72; stratified log-rank P = .027) with an 8-year OS rate of 63.0% and 55.1% for the CSC and SC arms, respectively. CSC also significantly improved the PFS (HR, 0.70; stratified log-rank P = .016). In conclusion, neoadjuvant DOS chemotherapy, as part of perioperative chemotherapy, prolonged the OS of Asian patients with LAGC relative to patients treated with surgery and adjuvant S-1. It should be considered one of the standard treatment options for patients with LAGC in Asia.

Long-Term Analysis of NRG Oncology RTOG 0415: A Randomized Phase III Noninferiority Study Comparing Two Fractionation Schedules in Patients With Low-Risk Prostate Cancer.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.NRG Oncology RTOG 0415 is a randomized phase III noninferiority (NI) clinical trial comparing conventional fractionation (73.8 Gy in 41 fractions) radiotherapy (C-RT) with hypofractionation (H-RT; 70 Gy in 28) in patients with low-risk prostate cancer. The study included 1,092 protocol-eligible patients initially reported in 2016 with a median follow-up of 5.8 years. Updated results with median follow-up of 12.8 years are now presented. The estimated 12-year disease-free survival (DFS) is 56.1% (95% CI, 51.5 to 60.5) for C-RT and 61.8% (95% CI, 57.2 to 66.0) for H-RT. The DFS hazard ratio (H-RT/C-RT) is 0.85 (95% CI, 0.71 to 1.03), confirming NI (P < .001). Twelve-year cumulative incidence of biochemical failure (BF) was 17.0% (95% CI, 13.8 to 20.5) for C-RT and 9.9% (95% CI, 7.5 to 12.6) for H-RT. The HR (H-RT/C-RT) comparing biochemical recurrence between the two arms was 0.55 (95% CI, 0.39 to 0.78). Late grade ≥3 GI adverse event (AE) incidence is 3.2% (C-RT) versus 4.4% (H-RT), with relative risk (RR) for H-RT versus C-RT 1.39 (95% CI, 0.75 to 2.55). Late grade ≥3 genitourinary (GU) AE incidence is 3.4% (C-RT) versus 4.2% (H-RT), RR 1.26 (95% CI, 0.69 to 2.30). Long-term DFS is noninferior with H-RT compared with C-RT. BF is less with H-RT. No significant differences in late grade ≥3 GI/GU AEs were observed between assignments (ClinicalTrials.gov identifier: NCT00331773).
