Promising studies have been conducted with many substances to reduce the ototoxic effects of cisplatin, but there is no treatment that completely eliminates the ototoxic effect.

To determine the effectiveness of astaxanthin (ASX) as a protective agent against cisplatin-induced ototoxicity.

Thirty-six rats were randomly divided into 6 groups. Group 1 received no drug injections except for anesthetics; group 2 received intraperitoneal (IP) olive oil only for 8 days; group 3 received only IP ASX 75 mg/kg dissolved in olive oil for 8 days; group 4 received a single dose of only IP 16 mg/kg cisplatin on the 5th day; group 5 received 25 mg/kg ASX IP daily for 8 days and a single 16 mg/kg dose of cisplatin on the 5th day; group 6 received 75 mg/kg ASX IP daily for 8 days and a single 16 mg/kg dose of cisplatin on the 5th day. The animals were tested for distortion product otoacoustic emissions (DPOAE) before and 3 days after cisplatin treatment. The animals in all groups were sacrificed under anesthesia on thety, prevent cellular degeneration and significantly reduce oxidative stress.
Extractions of third molars constitute about 90% of the scheduled surgical procedures performed by oral surgeons. Wisdom tooth surgery is associated with complications, such as the lingual and inferior alveolar nerve damage, bleeding, tooth/jaw fractures, tooth displacement into the adjacent anatomical spaces, trismus, infections, and other.

The aim of the study was to analyze complications after wisdom tooth extraction in patients treated at the Department of Oral Surgery of Jagiellonian University Medical College in Kraków, Poland, in the years 2016-2018.

A retrospective analysis of the medical records of 339 patients treated in the outpatient setting was performed. The inclusion criterion comprised a single extraction of a third molar. The exclusion criteria were multiple extractions, comorbidities and pregnancy. No antibiotic prophylaxis was used. The incidence of post-extraction complications, such as oroantral communication, postoperative hematoma, acute inflammation of the surrounding tissues, trdom tooth removal. Complications after the removal of third molars are most often inflammatory.
Lower third molars and the necessity of surgical extraction with root separation are risk factors for postoperative complications in patients who require wisdom tooth removal. Complications after the removal of third molars are most often inflammatory.
In the past 20 years, several studies and clinical trials have reported similar results for transmucosal implants as compared to submerged implants. Several advantages of immediate loading have been pointed out, such as the reduction of treatment time, trauma reduction, and immediate esthetic and functional improvements.

The main objective of this study was to clinically evaluate the implant survival rate in patients with total rehabilitation via implants that underwent immediate loading in the past 5 years.

A cross-sectional, descriptive, observational analysis was conducted. The implant survival rate for an edentulous maxilla or mandible was assessed with regard to the loading protocol by means of a questionnaire and clinical observation. The study included 103 patients with edentulous jaws rehabilitated with fixed prostheses on implants. Each patient received 4-6 implants. In total, 474 implants were placed. Factors such as the implant survival rate as well as biological and prosthetic complications were evaluated and analyzed statistically.

Of the 474 implants initially placed, 458 were considered osteointegrated and 16 were considered lost, which corresponds to a 96.62% implant survival rate. The most common types of failure were prosthetic fractures (46.2%), peri-implantitis (23.1%) and unscrewing (11.5%) in the first 5 years.

The rate of osseointegration for implants placed under immediate loading was extremely high, in accordance with the previously published studies, which led us to conclude that currently, this is a surgical procedure with a high rate of success and high predictability.

Triheptanoin is an odd-carbon, medium-chain triglyceride consisting of 3 fatty acids with 7 carbons each on a glycerol backbone developed to treat adult and pediatric patients with LC-FAODs. The pharmacokinetics of triheptanoin and circulating metabolites were explored in healthy subjects and patients with LC-FAODs using noncompartmental analyses. Systemic exposure to triheptanoin following an oral administration was negligible, as triheptanoin is extensively hydrolyzed to glycerol and heptanoate in the gastrointestinal tract. Multiple peaks for triheptanoin metabolites were observed in the plasma following oral administration of triheptanoin, generally coinciding with the time that meals were served. Heptanoate, the pharmacologically active metabolite of triheptanoin supplementing energy sources in patients with LC-FAODs, showed the greatest exposure among the metabolites of triheptanoin in human plasma following oral administration of triheptanoin. The exposure of heptanoate was approximately 10-fold greater than that of beta-hydroxypentoate, a downstream metabolite of heptanoate. Exposure to triheptanoin metabolites appeared to increase following multiple doses as compared with the single dose, and with the increase in triheptanoin dose levels.
To investigate the relationship between anxiety symptoms and factors related to clinical control and quality of life of children with asthma aged 7-12 years.

A cross-sectional comparative study involving children recruited from a reference center for asthma treatment in the city of Natal-RN. Diagnosis, control and severity were performed following GINA recommendations (2019). Sociodemographic information and spirometry results from a bronchodilator test were collected. Modified Fisher's scale, clinical control questionnaires (c-ACT and ACT), quality of life assessment (PAQLQ) (total score and domains) and anxiety symptoms assessment (SCAS) (total score and domains) were applied.

The sample consisted of 42 children with asthma. Symptoms of social phobia (as identified by SCAS), and household head education were related to clinical asthma control (p = .006; R
 = .19). Total SCAS score, guardian's education and physical activity were related to total PAQLQ (p < .0001; R
 = .33). MLSI3 SCAS was related to the activity limitation domain of PAQLQ (p = .004; R
 = .17). SCAS, gender, and physical activity were related to the PAQLQ symptoms domain (p = .003; R
 = .32). The guardian's education, physical activity practice, and the symptoms of separation anxiety, panic attack and agoraphobia (as identified by SCAS) were related to the emotional domain of PAQLQ (p = .004; R
 = .45).

The present study shows evidence of an association between anxiety symptoms, poorer clinical control, and health-related quality of life in children with asthma.

To explore in-depth the views on Internet-based psychological therapies and their implementation from the perspective of National Health Service (NHS) commissioners and managers.

Qualitative interview study.

Ten NHS commissioners and managers participated in a semi-structured, co-produced interview. Each transcribed interview was double-coded and thematically analysed using The Framework Method.

Interviews generated three main themes. (1) Capacity issues across psychological therapy services create barriers to face-to-face therapies, and Internet-based interventions offer a solution. (2) Despite reservations, there is growing acceptance of Internet-based therapies. Different ways of connecting with patients are required, and Internet-based treatments are accessible and empowering treatment options, with guided self-help (GSH) preferred. Internet-based interventions may however exclude some individuals and be a threat to the therapeutic relationship between patient and practitioner. (3) Successful rollh examining therapeutic alliance across Internet-based and face-to-face therapies. Challenges implementing Internet-based psychological therapies include therapist resistance to changing working practices in general, and inflexibility of the NHS, and national, coordinated implementation efforts are encouraged.
The salivary gland neoplasm of unknown malignant potential (SUMP) category reflects the cytomorphologic overlap and complexity of reporting salivary gland cytology in the Milan system. It includes neoplasms for which a diagnosis of a specific entity cannot be made and, more importantly, for which a carcinoma cannot be entirely excluded. For risk stratification, the subcategorization of SUMP based on the predominant cell type is recommended. This study was aimed at evaluating the risk of neoplasm (RON) and the risk of malignancy (ROM) of the basaloid and oncocytic subtypes of the SUMP category.

A retrospective analysis of 482 salivary gland fine-needle aspirations from 2012 to 2019 resulted in 48 SUMP cases. The cytology of these cases was reviewed and reclassified as the basaloid or oncocytic subtype. Surgical follow-up was available for 36 cases. The RON and ROM for each subtype were calculated.

The RON and ROM were 100% and 23%, respectively, for monomorphic basaloid tumors and 88% and 58.8%, respectiation.
ROP screening is vital in care of premature infants but is considered burdensome, difficult and time consuming for ophthalmologists. This study assessed the reduction in workload following the introduction of nurse-led WFDRI to a large neonatal nursery.

We report a retrospective audit of 628 infants screened for ROP in the years 2010, 2013 and 2019 at the Royal Women's Hospital, Victoria. The last complete year of screening for ROP using binocular indirect ophthalmoscopy (BIO) alone (2010) was compared with two subsequent years after the introduction of nurse-led WFDRI. The main outcome measures were the time taken to report and document WFDRI and the time taken to undertake BIO examination of a premature infant and document the results.

The ophthalmologist's time taken to conduct BIO, review images and document the results per 100 patient examinations was reduced from 16.7 hours before introduction of WFDRI to 3.7 hours. Similarly, the weekly time spent on this component of ROP screening fell from 2.3 hours per week to 0.8 and 1.0 hours per week after introduction of WFDRI.

The introduction of nurse-led WFDRI has resulted in a dramatic and sustained reduction in ophthalmologist workload involved in ROP screening in a large Australian neonatal nursery. This may result in improved retention of the ophthalmic workforce required to undertake ROP screening.
