Background: The primary study objective was to compare the cosmetic result of radioguided seed localization (RSL) with wire localization (WL).

Methods: A subgroup of patients enrolled in a multicentered, randomized trial comparing WL with RSL participated. Frontal photographs were taken 1 and 3 years postsurgery. The European Organization for Research and Treatment of Cancer Cosmetic Rating System was used to evaluate cosmesis outcomes by the patient and a panel of 5 raters.

Results: The study enrolled 73 patients (WL, n = 38; RSL, n = 35). Most patients rated their overall cosmesis as "excellent" or "good" (76% WL, 80% RSL). Patient and panel ratings on all cosmetic outcomes were similar between groups. Multivariable regression for overall cosmesis found larger specimen volume and reoperation to be predictors of worse ratings.

Conclusions: All cosmetic outcomes assessed were similar after WL and RSL. The comparable outcomes may reflect similar reoperation rates and volumes of excision between groups.

Background: There is consensus on the safety of standard dose direct oral anticoagulants (DOACs) for stroke prevention in patients undergoing cardioversion of atrial fibrillation (AF), but outcomes of reduced dose DOACs in this setting remain unclear.

Objective: This systematic review and meta-analysis aimed to compare the rate of cardioversion-associated thromboembolic events between patients taking reduced dose DOACs and those receiving standard dose anticoagulation.

Methods: A systematic search was conducted for studies published between January 1, 2009, and February 16, 2024 in PubMed, Embase, and Cochrane Central Register of Controlled Trials.

Background: YYD601 is a new dual delayed-release formulation of esomeprazole, developed to enhance plasma exposure and prolong the duration of acid suppression.

Purpose: This study aimed to evaluate the safety, pharmacokinetic (PK), and pharmacodynamic (PD) profiles of YYD601 20 mg following single and multiple oral administrations in healthy, fasting adult Koreans, and to compare these outcomes to those of the conventional esomeprazole 20 mg capsule.

Methods: A randomized, open-label, two-period crossover study was conducted in 28 participants, who were divided into two treatment groups: one group received YYD601 20 mg, and the other received conventional esomeprazole 20 mg, once daily for five consecutive days.

Objective: This randomized controlled trial (RCT) aimed to compare the short-, mid-, and long-term outcomes in patients with malignant intracranial hypertension undergoing either decompressive craniectomy (DC) or hinge craniotomy (HC).

Methods: In this prospective RCT, 38 patients diagnosed with malignant intracranial hypertension due to ischemic infarction, traumatic brain injury, or non-lesional spontaneous intracerebral hemorrhage, who required cranial decompression, were randomly allocated to the DC and HC groups.

Results: The need for reoperation, particularly cranioplasty, in the DC group was significantly different from that in the HC group.

Purpose: To evaluate the long-term impacts of the feedback intervention on controlling inappropriate use of antimicrobial prescriptions in primary care institutions in China, as a continuation of the previous feedback intervention trial.

Methods: After the intervention ended, we conducted a 12-month follow-up study. The prescription data were collected from the baseline until the end of the follow-up period.

Research on disease-related malnutrition and adherence to oral nutritional supplements (ONS) has increased in recent years. To guide future studies, it is important to identify trends in terminology use and intervention characteristics. This review aimed to map characteristics of research investigating adherence to ONS in patients with disease-related malnutrition and explore changes over time.
