ents who may benefit from novel therapeutic approaches to acute kidney injury.
Elevated C-C motif chemokine ligand 14 levels predict persistent acute kidney injury in cardiac surgery patients with moderate or severe acute kidney injury. This new biomarker may help stratify patients destined to receive renal replacement therapy and identify patients who may benefit from novel therapeutic approaches to acute kidney injury.
The thumb carpometacarpal (CMC) joint is the second most common site of osteoarthritis in the hand, yet reported symptoms and ultimate treatment decisions are not simply a function of radiographic appearance. This study aimed to determine the patient- and/or disease-related factors associated with patients undergoing surgical treatment of thumb CMC arthritis.

This retrospective cohort study analyzed 1,994 patients with thumb CMC arthritis treated at 2 institutions between February 2015 and November 2018. Patient demographic and clinical information was obtained from medical records to characterize treatment modalities before hand surgeon evaluation, mental and physical comorbidities, and Patient-Reported Outcomes Measurement Information System assessments. After bivariate analysis, a multivariable logistic regression model evaluated factors associated with undergoing thumb CMC surgery.

This cohort was predominately female (70%) and white (91%), mean age at first appointment, 62 ± 10 years. A total of 170 patients underwent surgery for thumb CMC arthritis (9%) at a median of 114 days (interquartile range, 27-328) after the first visit. Patient-Reported Outcomes Measurement Information System Depression scores correlated with Pain Interference and Physical Function scores. A history of diagnosed depression or anxiety was associated with less perceived Physical Function at presentation. However, only prior contralateral thumb CMC surgery, younger patient age, and treating institution were associated with undergoing surgery in regression modeling.

Pain and functional limitations associated with thumb CMC arthritis are influenced by mental health comorbidities, but these factors do not predict surgical treatment. Instead, patients' prior surgical experience and surgeon attitudes toward thumb CMC arthritis appear to have a strong influence on the odds of patients undergoing surgery for thumb CMC arthritis.

Prognostic IV.
Prognostic IV.Point of care ultrasound (POCUS) is the use of ultrasound (US) imaging technology by non-sonographer, non-radiologist treating clinicians. Handheld US systems are increasing in popularity and becoming widely available and easily accessible to hand surgeons in clinical practice. Adapting POCUS into the repertoire of the hand surgeon can aid in the diagnosis of many common hand surgery presentations and shorten operative times. click here In this review, we outline the potential uses and advantages of incorporating POCUS into hand surgery practice incuding its use in emergencies such as trauma, infections, and foreign body localization, as well as elective presentations such as nerve compression, procedural guidance, and anesthesia. Finally, this review outlines the training and curriculum development required to ensure safe implementation of POCUS into a hand surgery practice.
To evaluate vocal symptoms, voice characteristics and videolaryngoscopy in obese women before and after bariatric surgery.

Obese patients (18 to 59 years old), candidates for bariatric surgery were recruited. Evaluation times T1 (preoperative), T2 (after six months), T3 (after 12 months). Evaluated parameters weight, height, body mass index, abdominal and neck circumference, vocal self-assessment, perceptual and acoustic vocal assessment, and videolaryngoscopy.

A total of 37 obese women were included, average age 40.8 years. There was a decrease in anthropometric measurements between the preoperative assessment and after 12 months weight (121.18 ± 15.4 kg; 77.1 ± 11.6 kg), BMI (46.6 ± 6.95 kg/m
; 30 ± kg/m
), abdominal circumference (128 ± 16.1; 99.1 ± 12.1), and neck circumference (41.1 ± 5.85; 36.6 ± 3.02). Gastroesophageal (21.6%) and vocal symptoms (27%) prevailed. No difference was identified in vocal self-assessment between the evaluations. In the acoustic analysis, f0 increased and the soft phonation index decreased. The perceptual analysis registered lower scores for the degree of dysphonia (G) and voice instability (I). The maximum phonation time values increased without changing the s/z ratio. Videolaryngoscopies showed a posterior middle cleft and improvement in the signs of reflux.

Bariatric surgery led to an important and gradual decrease in anthropometric parameters. The voice became less hoarse, with higher pitch and more stable, with an improvement in maximum phonation time, however with slight breathiness. Such changes were not noticed by the patients.

However, the harmful effects associated with such secondary emissions have yet to be thoroughly understood, especially in the spatial and temporal context, as the existing literature has a clear sampling bias with the best recognition of sites in the European Alps. In this review, we elaborated on the hazards associated with the rapid melting of glaciers releasing organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and polycyclic aromatic hydrocarbons (PAHs). To this end, we collated knowledge on (1) the varying glacier melt rate across the Northern Hemisphere, (2) the content of POPs in the glacial system components, including the less represented areas, (3) the mechanisms of POPs transfer through the glacial system, including the importance of immediate emission from snow melt, (4) risk assessment associated with POPs re-emission.
