Adherence to positive airway pressure (PAP) therapies is poor, particularly among low-income populations and racial minorities. This study tested a low-resource, brief telephonic health coaching intervention to improve PAP adherence.

Post hoc analysis of a quality improvement initiative in which English- and Spanish-speaking patients from a county-based public health system were randomly assigned to receive health coaching or usual care. An unlicensed, trained health coach called patients three times to resolve barriers to adherence. A per-protocol analysis was conducted for adherence measures collected by device modem at baseline and 30 days.

Of 131 people for whom device data were available, 56 were randomized to health coaching and 75 to usual care. At baseline, 47.3% of patients had used their device at any time in the past 30 days, with a mean of 2 hours of use per night. At 30 days, adjusting for baseline, patients in the coaching arm were more likely than usual care patients to use their device (55.4% vs. 41.3%, p = 0.03), and they increased their use for 0.4 hours over usual care (p = 0.04).

This pilot study suggests that a low-cost intervention could be effective at improving PAP adherence, even in a population known to have poor adherence and among long-term PAP users with poor adherence. Future research may examine whether a higher-touch intervention or one using videoconferencing yields greater improvements. This promising intervention warrants further study.

Tympanoplasty is a surgical procedure designed to reconstruct the mechanisms of sound transmission in the middle ear.

Analyze, from an audiological point of view, patients with chronic otitis media undergoing type 3 tympanoplasty major columella with total ossicular replacement titanium prosthesis or with cartilage graft stapes columella.

This is a prospective analytical study, carried out at the otorhinolaryngology outpatient clinic in a tertiary care hospital, through the evaluation of 26 patients with chronic otitis media who underwent tympanoplasty using different materials for auditory rehabilitation such as titanium prostheses or cartilage autografts.

There was no statistically significant association between the group factors (cartilage or titanium reconstruction) and preoperative variables. There was no statistically significant association between the postoperative characteristics of the patients and the type of reconstruction. Neither subjective improvement (hearing improvement) nor residual perforation were associated with a type of material. The via factor was the only one that showed a statistically significant difference once air-conduction pathway improved more than bone-conduction pathway, decreasing the air-bone gap.

There was no statistical difference between the two groups in relation to the audiometric improvement. There was hearing improvement in both groups. More studies must be done with a longer follow-up to better evaluate the outcome.

Papillary thyroid carcinoma is the most frequent endocrine neoplasia and its incidence has tripled over the past 35 years. Although papillary thyroid carcinoma carries a good prognosis, 10%-30% of patients still develop recurrence and metastasis. Some clinical and genetic features are associated with worse prognosis. The most frequent mutation is the BRAF p.V600E, which has been associated with many clinical features of poor prognosis. However, many studies have produced controversial results without any association between BRAF mutation and clinicopathological features of poor prognosis.

Since the prognostic value of BRAF mutations remains controversial, this study aims to investigate the importance of this mutation in therapeutic decisions for papillary thyroid carcinoma.

Therefore, we evaluated whether the presence of BRAF mutation is associated with features of poor prognosis in 85 patients with papillary thyroid carcinoma older than 45 years treated at A.C. Camargo Cancer Center, from 1980 to 2007. testing is widely available, there are no consistent data to support improvement in outcomes from incorporating it into therapeutic decision for thyroid cancer.
Proliferation markers play a significant role in the biologic behavior of tumors. Geminin is a known inhibitor of the cell cycle and DNA replication and has not been previously reported in cutaneous basal and squamous cell carcinomas of the head and neck.

We aimed to investigate proliferation markers ki67, MCM2, and geminin in head and neck cutaneous basal and squamous cell carcinomas.

Forty cases of each tumor were immuostained with ki67, MCM2, and geminin followed by assessment of labeling indices (LIs). MCM2/ki67- and geminin/ki67-ratios were also determined; t-test was used for statistical analysis (p<0.05).

There was no significant difference in ki67 (p=0.06) and MCM2 (p=0.46) between cutaneous basal and squamous cell carcinomas; however, geminin LI was significantly higher in squamous cell carcinomas compared to cutaneous basal cell carcinomas (p<0.001). Only geminin/ki67 showed a significant difference between the two tumors with the ratio showing significantly higher numbers in squamous cell carcinomas (p=0.015).

Geminin could be regarded as an effective factor in the pathogenesis of head and neck cutaneous cutaneous basal cell carcinomas and squamous cell carcinomas and may be one of the responsible elements in the difference between the biologic behavior of these tumors.

We present a case of an exceptionally young, 21-year-old patient with surprisingly rapid tumor progression and answer the question, what was the reason for such uncontrolled tumor growth. The main concern is the diagnostic challenge and a peculiar, one week race against time and tumor progression so that the least disfiguring surgery could be done.Low- and middle-income countries (LMICs) remain neglected in the Coronavirus 19 (COVID-19) pandemic. COVID-19 convalescent plasma (CCP) (i.e. plasma collected from individuals after their recovery from COVID-19) has emerged as a leading medical treatment for COVID-19. Studies to date support the safety-and increasingly the efficacy-of CCP to treat COVID-19. This has motivated large-scale procurement and transfusion of CCP, notably in the United States (US), where inventories of CCP have been attained, and government-supported stockpiling of CCP is underway. CCP is a therapy that could be implemented in LMICs. However, systemic and transfusion-specific challenges (e.g. capacity for donor mobilization and collections) impede local procurement of this resource in sufficient volumes to meet clinical demand. This raises the question as to whether there are strategies to facilitate sharing of CCP with LMICs and/or bolstering local capacity for collection to contend with the health crisis. While compelling, there are cost-related, logistical and regulatory barriers to both approaches. For one, there is complexity in diverting national interest (e.g. in the US) away from an epidemic that displays few signs of abating. There are also concerns regarding equitable distribution of CCP in LMICs and how that might be overcome. Further, the barriers to blood donation in general apply to collection of CCP; these obstacles are longstanding, accounting for the inability of many LMICs to meet their blood transfusion needs. Nonetheless, CCP affords dual opportunity for humanitarian outreach while tackling a broader challenge of blood transfusion safety and availability.The past 20 years of experience with umbilical cord blood transplantation have demonstrated that cord blood is effective in the treatment of a spectrum of diseases, including hematological malignancies, bone marrow failure, hemoglobinopathies, and inborn errors of metabolism. However, only a few number of umbilical cord blood units collected have a cell content adequate for an allogenic hematopoietic stem cell transplantation. find more In the meanwhile, there is an increasing interest in exploiting cord blood derivatives in different fields. In this review, we will summarize the most recent updates on clinical applications of umbilical cord blood platelet derivatives for regenerative medicine, and we will revise the literature concerning the use of umbilical cord blood for autologous or allogeneic transfusion purposes. The methodological aspect and the biological characteristics of these products also will be discussed.Neonates and prematures are among the most transfused categories of patients. Adverse reactions due to transfusions, such as transfusion-transmitted infections, can affect the rest of their lives. In this systematic review, we revised the literature concerning transfusion-transmitted infection in neonates. We reported case-reports and case-series previously published and we integrated these data with our experience at local neonatal intensive care unit. Moreover, we illustrated strategies for mitigating transfusion-transmitted infections, including donor selection and testing, pathogen inactivation technologies and combined approaches, as for Cytomegalovirus infection, integrating leukoreduction and identification of seronegative donors.
Beta thalassemia major (BTM) is characterized by anemia and iron overload, especially with inadequate chelation therapy. Dual energy x-ray absorptiometry software (DXA) may misanalyse bone measurements due to iron deposition in organs such as the liver. Our objective was to study difference between the posterior-anterior spine measurements of bone mineral content (BMC), area (BA) and density (BMD) in poorly chelated beta thalassemia patients with and without inclusion of the liver in the DXA analysis.

We studied hemoglobin and serum ferritin concentrations in 208 patients with BTM (children n = 177, young adults n = 31). Posteroanterior spine measurements BMC, BA and areal BMD were performed using a GE iDXA. Using the tissue point typing feature (EnCore software, version 16), analysis was carried out including and excluding (manually) the iron overloaded liver. Machine generated Z-scores of L1-L4 BMD were used for analysis.

The mean age of the study group was 12.9 ± 5.4 yr. Mean hemoglobin and serum fered tissues need to be manually excluded during analysis of the PA spine.
