Carbon paper was found to be resistant to solvents and to be stable for pH ⩾ 7. Composites revealed electrical conductivity. The covalent network between the graphene layers and CS, suggested by the IR findings, accounts for these results. This work demonstrates the effectiveness of a continuous covalent network between chitosan and graphene layers edge functionalized with tailor made functional groups for the preparation of carbon papers and aerogels and paves the way for the scale up of such a type of composites.Maxillary osteomyelitis is a rare event. With emergence of bisphosphonates, the incidence of jaw osteomyelitis has increased. We report five uncommon cases, with a comprehensive review of etiology and pathology. The correlation between osteonecrosis and osteomyelitis is discussed.

Our previous research found very high levels of burnout and mental health problems among medical students across Indonesia, in line with rates in many other countries. This study further analyses the data by comparing six different regions of Indonesia to determine any differences between them on such measures and to look for possible explanations.

Our sample of 1,729 students reported high levels of burnout and 'mild' psychiatric illness across all six regions. There were however significant differences between some regions. Sumatran students reported the lowest scores for both the Oldenburg Burnout Inventory (OLBI) and General Health Questionnaire 12 (GHQ12) scales. Sources of stress also varied among regions, with relationships and study the most reported. Further exploration of possible cultural differences is needed as well as prompt mental health support for medical students.

We found that DR-TB infected children have nonetheless a high treatment completion rate with a low incidence of fatality and treatment failure. Reversible adverse drug reactions are common during therapy.

Safe handling of oral anticancer agents is of great concern. There is a lack of clear, national guidelines on how patients can safely handle and dispose of unwanted medications. We aimed to evaluate the safe handling, storage, and disposal of oral anticancer drugs among cancer patients and caregivers at home.

This cross-sectional survey of adult cancer patients (or their adult caregivers) used a closed-ended questionnaire from May 2019 to March 2020.

A total of 257 patients (50 ± 15 years; range 18-93 years) were enrolled; however, only 91% (233/257) reported self-administering oral anticancer medications. Caregivers were more likely to administer oral anticancer agents for patients ≥60 years than those <40 years old (63%

8%;

 = 0.001). Most patients (52%; 133/257) did not wash their hands after administering the drug; 74% (164/222) of the respondents reported that their medications were kept in a bedroom cabinet, while 18% (40/222) stored their medications in a refrigerator, and 5% (12/222) in a kitchen cabinet. A total of 55% (68/124) of patients returned their excess oral chemotherapy medications to the hospitals; however, 36% (45/124) disposed of their unused oral chemotherapy drugs in a household garbage container.

While two-thirds of patients stored their oral anticancer medications properly, more than half used inappropriate handling procedures. Disposal practices were inconsistent and did not adhere to the reported international guidelines.

Clinical indications of immune checkpoint inhibitors have expanded to a variety of malignancies. Nearly 50% of patients with advanced cutaneous squamous cell carcinoma, respond to the programmed-death 1 inhibitor cemiplimab. To date, insulin-dependent diabetes mellitus has been documented with the use of several immune checkpoint inhibitors but not cemiplimab.

We report herein the first case of a patient with cutaneous squamous cell carcinoma who developed diabetic ketoacidosis and insulin-dependent diabetes mellitus following only two cycles of cemiplimab. A score of 6 on the Naranjo nomogram makes the causality relationship between cemiplimab use and the insulin-dependent diabetes mellitus probable.

The patient's developed diabetic ketoacidosis was managed with intravenous fluids and intravenous insulin, with a prompt resolution. selleck products Cemiplimab was discontinued, and the patient was discharged on long-acting and short-acting insulin therapy, with a follow-up with endocrinology.

The mechanism by which cemiplimab caused insulin-dependent diabetes mellitus is most likely due to lack of endogenous insulin production in the setting of immune-mediated loss of pancreatic beta-cells. Patients may benefit from fasting blood glucose monitoring and early immune checkpoint inhibitor discontinuation where elevated serum glucose is detected.

It controls synaptic transmission and plasticity by maintaining the appropriate phosphorylation status of many ion channels present at presynaptic and postsynaptic sites. As such, normal calcineurin activity in neurons and synapses is mainly involved in negative feedback regulation in response to increased neuronal activity and intracellular Ca2+ levels. Calcineurin inhibitors (e.g., cyclosporine and tacrolimus) are widely used as immunosuppressants in tissue and organ transplantation recipients and for treating autoimmune diseases but can cause severe pain in some patients. Furthermore, diminished calcineurin activity at the spinal cord level may play a major role in the transition from acute to chronic neuropathic pain after nerve injury. Restoring calcineurin activity at the spinal cord level produces long-lasting pain relief in animal models of neuropathic pain. In this article, we provide an overview of recent studies on the critical roles of calcineurin in regulating glutamate NMDA and AMPA receptors, voltage-gated Ca2+ channels, potassium channels, and transient receptor potential channels expressed in the spinal dorsal horn and primary sensory neurons.Seven aspects of the management of acute scaphoid fractures are open to debate Diagnosis of true fractures among suspected fractures, assessment of fracture displacement, cast immobilization strategies, the role of surgical fixation, proximal pole fractures, assessment of union, and the underlying objective of treatment. We reviewed current evidence, and our varied interpretations of it, to highlight areas of uncertainty where more evidence might be helpful.The attachment theory has commonly been used to examine intimate partner psychological aggression (IPPA), but few studies have examined its association with self-reported justifications for one's own use of IPPA. Behaviors, including the use of IPPA, are influenced, maintained, and function within the context of their justifications, highlighting the importance of investigating these justifications to obtain a clearer picture of IPPA. This study examined whether insecure romantic attachment (i.e., attachment anxiety and attachment avoidance) in both partners of a couple was associated with their justifications for their own use of IPPA. A community sample of 81 mixed-sex couples who reported using IPPA in the last year completed self-reported questionnaires on adult romantic attachment and their justifications for their use of IPPA. Results of a path analysis based on the actor-partner interdependence model revealed moderate positive associations between attachment anxiety and one's use of internal and external justifications for their IPPA perpetration in men and women. An unexpected dyadic positive association is discussed. These results suggest that the use of justifications for one's use of IPPA may reflect a strategy of hyperactivation that could contribute to the cycle of psychological aggression. Uncovering the function of these justifications could provide important therapeutic benefits, which are discussed in the study's implications.

Capecitabine is an orally administered prodrug that converts preferentially to 5-fluorouracil within tumors, resulting in enhanced concentrations of 5-fluorouracil in tumor tissue. The use of capecitabine has shown efficacy in the metastatic setting for breast cancer, and more recently, efficacy as adjuvant therapy for triple-negative breast cancer (TNBC). Capecitabine has been shown to be well tolerated with minimal side effects, but the incidence of leukoencephalopathy is rare with a risk of less than one percent.

We report on a 34-year-old female patient with left TNBC, moderately differentiated, stage IIB that experienced symptoms of neurotoxicity following initiation of adjuvant chemotherapy with capecitabine.

Naranjo Algorithm Assessment score of nine indicated patient had drug-induced leukoencephalopathy leading to discontinuation of capecitabine and resolution of the neurotoxicity symptoms.

Early detection of capecitabine-induced neurotoxicity by magnetic resonance imaging is crucial as symptoms may be reversible to the condition that capecitabine is immediately discontinued.

External ear canal exostoses are usually bilateral and broad-based, secondary to external ear canal chronic cold exposure, especially water.

The objectives were to analyze the influence of the surgeon's experience on the 3-year recurrence and on the complication. We also studied the influence of prolonged exposure to cold water on the incidence of recurrence.

This monocentric retrospective study included 98 ears operated for canalplasty between 2009 and 2016 by nine different operators including one senior, a junior, and seven beginner surgeons. Senior, Junior, and Beginner groups were compared.

3-year recurrence rate was higher in the Beginner and Junior groups than in the Senior group (69% and 38% vs 18%,

= .001). Although there was a difference between the Beginner (69%) and Junior (38%) groups, it was not significant (

= .407). Among the recurrences, 48% had continued exposure to cold water while only 7% of the ears without recidivism were still exposed (

< .001, OR = 1.25 [4.4; 36.1]). The complication rates were similar between groups, concerning pain (8% vs 30% vs 12%), per procedure perforation (17% vs 10% vs 16%), scarring disorders (25% vs 20% vs 13%), and osteitis (8% vs 0% vs 1%).
