To assess retear rates in arthroscopic double-row rotator cuff repair (double-row RCR) with and without platelet-rich therapy (PRT).
Systematic review and meta-analysis of randomized controlled trials (RCTs). MEDLINE, Embase, and Scopus databases were searched for RCTs involving use of PRT exclusively in arthroscopic double-row RCR. A random-effects model and the generic inverse variance method were used for quantitative data synthesis. Heterogeneity was tested with the I
statistic index.
The 9 RCTs included in the meta-analysis demonstrated a risk reduction of 49% for retears in patients receiving PRT (risk ratio [RR] 0.51; 95% confidence interval [CI] 0.35 to 0.76; P= .0008; I
= 0%). Divided by tear sizes, retear risk reduction of 47% (RR 0.53; 95% CI 0.30 to 0.95; P= .03; I
= 0%) was found in small to medium tears and 51% (RR 0.49; 95% CI 0.29 to 0.84; P= .009; I
= 0%) in large to massive tears. Linked double-row RCR resulted in risk reduction of 51% for retears in comparison with nonlinked repairs.
Double-row RCR plus PRT significantly reduced retear rates in all sizes of rotator cuff tears. Linked double-row RCR and applying the PRT during the surgical procedure and in the tendon-bone interface reproduced the best outcomes. Clinically, all patients improved, and no statistically significant difference was seen in clinical and functional scores between the intervention groups. All patients achieved optimal values for patient-reported outcomes measures.

Tuberculosis (TB) is one of the top ten causes of deaths worldwide and the leading cause of death from a single infectious agent. The conventional TB drug therapy requires a long term treatment with frequent and multiple drug dosing with a stiff administration schedule, which results in low patient compliance. This eventually leads to the recurrence of the infection and the emergence of multiple drug resistance. Hence, there is an urgent need to develop more successful and effective strategies to overcome the problems of drug resistance, duration of treatment course and devotion to treatment. Nanotechnology has considerable potential for diagnosis, treatment and prevention of infectious diseases including TB. The main advantages of nanoparticles to be used as drug carriers are their small size, high stability, enhanced delivery of hydrophilic and hydrophobic drugs, intracellular delivery of macromolecules, targeted delivery of drugs to specific cells or tissues, and the feasibility of various drug administration routes. Moreover, these carriers are adapted to facilitate controlled, slow, and persistent drug release from the matrix. Above properties of nanoparticles permit the improvement of drug bioavailability and reduction of dosing frequency and may reduce the toxicity and resolve the problem of low adherence to the prescribed therapy. In this review, various types of nanocarriers have been evaluated as promising drug delivery systems for different administration routes and main research outcomes in this area have been discussed.
Dysfunctional connectivity within the perceptual hierarchy is proposed to be an integral component of psychosis. The fragmented ambiguous object task was implemented to investigate neural connectivity during object recognition in patients with schizophrenia (SCZ) and bipolar disorder and first-degree relatives of patients with SCZ (SREL).
We analyzed 3T functional magnetic resonance imaging data collected from 27 patients with SCZ, 23 patients with bipolar disorder, 24 control subjects, and 19 SREL during the administration of the fragmented ambiguous object task. Fragmented ambiguous object task stimuli were line-segmented versions of objects and matched across a number of low-level features. Images were categorized as meaningful or meaningless based on ratings assigned by the participants.
An a priori region of interest was defined in the primary visual cortex (V1). In addition, the lateral occipital complex/ventral visual areas, intraparietal sulcus (IPS), and middle frontal gyrus (MFG) were identifins of aberrant connectivity among low-level, mid-level, and high-level visual areas in patients with SCZ, patients with bipolar disorder, and SREL.
Posttraumatic stress disorder (PTSD) is associated with altered processing of threat-related stimuli. Neurobiological models implicate right amygdala hyperreactivity in these alterations, but this potential biomarker also has been observed in individuals exposed to adverse childhood experiences (ACEs) (i.e., abuse and neglect) without psychopathology. Separation of the differential contributions of PTSD and ACEs to amygdala reactivity might benefit from incorporating the developmental timing of the events.
We conducted comprehensive retrospective interviews assessing ACEs for each life year between the ages of 1 and 17 years in a sample of 60 women exposed to trauma (including 34 participants with PTSD and 26 healthy participants). Functional magnetic resonance imaging was used to extract amygdala reactivity to threatening versus neutral scenes. find more Amygdala reactivity was predicted from PTSD diagnosis, total ACE severity, and ACE severity by life year using random forest regression.
PTSD and ACEs significato threat may help to uncover interactions between traumatization and development of PTSD.
Preeclampsia, which disproportionately affects Black women, is a leading cause of preterm delivery and risk for future hypertension and chronic kidney disease (CKD). Apolipoprotein L1 (APOL1) kidney risk alleles, common among Black individuals, contribute substantially to CKD disparities. Given the strong link between preeclampsia and CKD, we investigated whether maternal and fetal APOL1 risk alleles can jointly influence preeclampsia risk, and explored potential modifiers of the association between APOL1 and preeclampsia.
Nested case-control study.
426 Black mother-infant pairs (275 African Americans and 151 Haitians) from the Boston Birth Cohort.
Maternal and fetal APOL1 risk alleles.
Preeclampsia.
Logistic regression models with adjustment for demographic characteristics were applied to analyze associations between fetal and maternal APOL1 risk alleles and risk of preeclampsia and to investigate the effects of modification by maternal country of origin.
Fetal APOL1 risk alleles tended to be associated with an increased risk of preeclampsia, which was not statistically significant in the total genotyped population.
