Digital assessment of supracrestal tissue attachment and its correlation with dentogingival components.

Background: The aim of this study is to measure, in vivo, the supracrestal tissue attachment dimensions (STADs) by means of a noninvasive digital method and to investigate the association between STADs and gingival thickness (GT), tooth position, tooth length, tooth width, keratinized tissue width (KTW), buccal bone thickness (BBT), and bone crest (BC) level.

Methods: Nineteen periodontally healthy subjects who previously received full mouth periodontal charting, cone beam computed tomography, and intraoral scan for the purpose of implant planning were included in the study. A digital imaging software was used for the superimposition of Digital Imaging and Communications in Medicine and stereolithography files, along with hard and soft tissue measurements.

Prophylactic Tranexamic Acid Prevents Postpartum Hemorrhage and Transfusions in Cesarean Deliveries: A Systematic Review and Meta-analysis.

Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide and PPH resulting in transfusion is the most common maternal morbidity in the United States. Literature demonstrates that tranexamic acid (TXA) can reduce blood loss in cesarean deliveries; however, there is little consensus on the impact on major morbidities like PPH and transfusions. We conducted a systematic review/meta-analysis of randomized controlled trials (RCTs) to evaluate if administration of prophylactic intravenous (IV) TXA prevents PPH and/or transfusions following low-risk cesarean delivery.

Impact of osteopathic manipulative techniques on the management of dizziness caused by neuro-otologic disorders: systematic review and meta-analysis.

Context: Osteopathic manipulative treatment (OMT) has been utilized by osteopathic clinicians as primary or adjunctive management for dizziness caused by neuro-otologic disorders. To our knowledge, no current systematic reviews provide pooled estimates that evaluate the impact of OMT on dizziness.

Objectives: We aimed to systematically evaluate the effectiveness and safety of OMT and analogous techniques in the treatment of dizziness.

Augmented Weighted Estimators Dealing with Practical Positivity Violation to Causal inferences in a Random Coefficient Model.

The inverse probability of treatment weighted (IPTW) estimator can be used to make causal inferences under two assumptions: (1) no unobserved confounders (ignorability) and (2) positive probability of treatment and of control at every level of the confounders (positivity), but is vulnerable to bias if by chance, the proportion of the sample assigned to treatment, or proportion of control, is zero at certain levels of the confounders. We propose to deal with this sampling zero problem, also known as practical violation of the positivity assumption, in a setting where the observed confounder is cluster identity, i.e.
