Prognostic significance of phase analysis using SPECT myocardial perfusion imaging in heart failure: a systematic review and meta-analysis.

Left ventricular mechanical dyssynchrony (LVMD) is an important prognostic factor for heart failure (HF). Phase analysis of myocardial perfusion SPECT is actively being researched to evaluate LVMD. We performed a systematic review and meta-analysis on the prognostic significance of LVMD using gated SPECT in HF patient.

Maximum standardized uptake value-to-tumor size ratio in fluorodeoxyglucose F18 positron emission tomography/computed tomography: a simple prognostic parameter for non-small cell lung cancer.

Purpose: By correcting the effect of tumor size on metabolic activity, the maximum standardized uptake value-to-tumor size (SUV:tumor size) ratio on fluorodeoxyglucose F18 positron emission tomography (F-FDG PET)/computed tomography (CT) scans can be a prognostic parameter of non-small cell lung cancer (NSCLC). The current study evaluates the prognostic value of SUV:tumor size ratio on pretreatment F-FDG PET/CT scans in patients with NSCLC. Furthermore, the SUV:tumor size ratio is compared with other established PET parameters.

Prognostic value of left ventricular mechanical dyssynchrony indices derived from gated myocardial perfusion SPECT in coronary artery disease: a systematic review and meta-analysis.

Purpose: Left ventricular mechanical dyssynchrony (LVMD) is an important prognostic factor in coronary artery disease. A growing body of evidence indicates that LVMD parameters derived from phase analysis of gated myocardial SPECT may allow risk stratification for future cardiac events. We performed a systematic review and meta-analysis on the prognostic value of LVMD on gated SPECT in patients with coronary artery disease.

Prevalence of Women in Medicine Programs at University-Based Internal Medicine Residency Programs.

Objective: Women physicians face various forms of inequities during their training process that inhibit them from reaching their full potential. As a response, several academic institutions have established women in medicine (WIM) programs as a support system. Our objective was to investigate the prevalence of WIM programs at university-based Internal Medicine residency programs as of December 2021.

Lymphatic remapping by long-term lymphoscintigraphy follow-up in secondary lymphedema after breast cancer surgery.

The purpose of the study is to investigate long-term changes on lymphoscintigraphy and their association with clinical factors in breast cancer-related lymphedema (BCRL) patients. This single-center cohort study included BCRL patients who underwent baseline and follow-up lymphoscintigraphy. The percentage of excessive circumference (PEC) of the affected upper limb compared with the unaffected side was used as an indicator of the clinical severity of BCRL.

Refractive Predictability between Standard and Total Keratometry during the Femtosecond Laser-Assisted Cataract Surgery with Monofocal Intraocular Lens with Enhanced Intermediate Function.

Purpose: We aimed to compare the accuracy of the intraocular lens (IOL) calculation formula using the standard keratometry (K) and total K (TK) during the femtosecond laser-assisted cataract surgery (FLACS) with a monofocal IOL with enhanced intermediate function using currently used formulas.

Methods: A retrospective review of 125 eyes from 125 patients who had undergone FLACS with implantation of monofocal IOL with enhanced intermediate function was conducted. The predicted refractive power was calculated using an optical biometer (IOLmaster 700) according to the K and TK in the Barrett Universal II, SRK/T, Haigis, and Holladay 2 formulas.

Biocompatibility and Transplantation Efficacy of the C-Clear Artificial Cornea in a Rabbit Chemical Burn Model.

It is difficult to detect multiple myeloma (MM) infiltration of the bone marrow on computed tomography (CT) scans of patients with osteopenia. Our aim is to determine the feasibility of using radiomics analysis to detect MM infiltration of the bone marrow on CT scans of patients with osteopenia. The contrast-enhanced thoracic CT scans of 104 patients with MM and 104 age- and sex-matched controls were retrospectively evaluated.

The Combined Inoculation of AR11 and Biochar Stimulates Synthetic Silicon and Potassium Phosphate Use Efficiency, and Mitigates Salt and Drought Stresses in Rice.

Synthetic chemical fertilizers are a fundamental source of nutrition for agricultural crops; however, their limited availability, low plant uptake, and excessive application have caused severe ecological imbalances. In addition, the gravity of environmental stresses, such as salinity and water stress, has already exceeded the threshold limit. Therefore, the optimization of nutrient efficiency in terms of plant uptake is crucial for sustainable agricultural production.

Patients Report Infrequent Counseling by Physicians and Inadequate Knowledge about Inflammatory Bowel Disease and Reproductive Health Issues.

Objective: Inflammatory bowel disease (IBD) reproductive health counseling is associated with higher knowledge, lower voluntary childlessness, greater medication adherence during pregnancy, and improved outcomes of pregnancy. Our aims were to assess counseling and knowledge about IBD and reproductive health in a tertiary care IBD patient population.

Study Design: We anonymously surveyed women and men ages 18 to 45 cared for at the Stanford IBD clinic about reproductive health and administered the CCPKnow questionnaire.

A Case of Glomus Tumor Mimicking Neuroendocrine Tumor on Ga-DOTATOC PET/CT.

 Ga-DOTA-peptide PET/CT is a valuable tool for diagnosing neuroendocrine tumors (NET). Various tumors and normal human tissue express the somatostatin receptor (SSTR), warranting attention to positive findings on  Ga-DOTA-peptide PET/CT. However, overexpression of SSTR in glomus tumors has not yet been reported.

Comprehensive Updates in the Role of Imaging for Multiple Myeloma Management Based on Recent International Guidelines.

The diagnostic and treatment methods of multiple myeloma (MM) have been rapidly evolving owing to advances in imaging techniques and new therapeutic agents. Imaging has begun to play an important role in the management of MM, and international guidelines are frequently updated. Since the publication of 2015 International Myeloma Working Group (IMWG) criteria for the diagnosis of MM, whole-body magnetic resonance imaging (MRI) or low-dose whole-body computed tomography (CT) and F-fluorodeoxyglucose positron emission tomography/CT have entered the mainstream as diagnostic and treatment response assessment tools.

The clinical spectrum of periorbital vascular complications after facial injection.

Background: Serious complications due to periorbital vascular occlusion can occur after facial injections, including skin necrosis, ophthalmoplegia, blepharoptosis, and visual loss. Visual loss after facial filler injection is particularly rare, but it is known to have a poor prognosis despite treatment.

Aims: This study aimed to describe the prognosis and various clinical features of periorbital vascular complications after facial injection of cosmetic filler or local anesthetic.

Preoperative nutritional risk index and postoperative one-year skeletal muscle loss can predict the prognosis of patients with gastric adenocarcinoma: a registry-based study.

Background: Patients with gastric cancer have an increased nutritional risk and experience a significant skeletal muscle loss after surgery. We aimed to determine whether muscle loss during the first postoperative year and preoperative nutritional status are indicators for predicting prognosis.

Methods: From a gastric cancer registry, a total of 958 patients who received curative gastrectomy followed by chemotherapy for stage 2 and 3 gastric cancer and survived longer than 1 year were investigated.
