Abstract	In this work, periodic mesoporous organosilicas (PMO) functionalized with the organic sentisizer naphthalenediimide (NDI) were employed as heterogeneous catalysts for the photodegradation of the antibiotic sulfadiazine (SDZ), taken as a model for contaminants of emerging concern (CECs). The catalysts, designated as PMONDI, were prepared by surfactant-directed co-condensation of the precursor N,N'-bis(3-triethoxysilylpropyl)- 1,4,5,8-naphthalenediimide with tetraethoxysilane. The synthesized PMONDI were characterized using transmission electron microscopy, nitrogen adsorption isotherms and small and large angle x-ray scattering. The performance of PMONDI catalysts in the photodegradation of SDZ was compared to that of TiO

Abstract	Background: Cutaneous basal cell carcinoma (cBCC) incidence has been increasing, but there are no available data on its epidemiological, clinical, and pathological patterns in Northeast Portugal. cBCC is mainly located in the head and neck, where the ear, neck, and throat (ENT) surgeon may have a major role. We aimed to verify the clinicopathological characteristics of basal cell carcinomas diagnosed in an ENT department. Methods: We performed a retrospective clinicopathological evaluation of the head and neck cBCC cases followed up at the Centro Hospitalar de Trás-os-Montes e Alto Douro (CHTMAD) ENT Department between January 2007 and April 2021. Results: One hundred seventy-four patients with 293 cBCCs were included in this retrospective study. We observed that about one-third of the patients had multiple cBCCs (30.5%) and an infiltrative-type growth pattern (39.3%), both features considered as patterns that are more aggressive. Infiltrative-type growth pattern cBCCs were significantly larger when compared with the indolent-type growth pattern (16.2 mm vs 10.8 mm). Conclusions: To the best of our knowledge, this is the first study about cBCC in a patient population followed up at an ENT hospital department. This study has shown that these patients had cBCCs with more aggressive features, making these tumors an important issue for the ENT surgeon.

Abstract	Basal cell carcinoma is the most frequent malignant neoplasm in white-skinned individuals. It develops in different body areas, including in the scalp, which is a unique anatomical region due to the high number of pilosebaceous follicles; the scalp is protected from UV exposure, a main risk factor for basal cell carcinoma development. Moreover, scalp basal cell carcinoma has been described as more aggressive and difficult to treat than other forms of basal cell carcinoma. In this study, we reviewed the clinical and pathological characteristics, risk factors, genetics, and treatment options for scalp basal cell carcinoma to better understand this special type of cancer. Even though it is not yet clear whether scalp basal cell carcinomas represent a different entity, it seems important to give them special attention due to their potential aggressiveness, invasion capacities, tendency to relapse, and treatment difficulties.

Abstract	Plant pathogenic fungi often developed specialized infection structures to breach the outer surface of a host plant. These structures, called appressoria, lead the invasion of the plant by the fungal hyphae. Studies in different phytopathogenic fungi showed that appressorium formation seems to be subordinated to the cell cycle. This subordination ensures the loading in the invading hypha of the correct genetic information to proceed with plant infection. However, how the cell cycle transmits its condition to the genetic program controlling appressorium formation and promoting the plant's invasion is unknown. Our results have uncovered how this process occurs for the appressorium of

Abstract	Surgery is the main approach for skin cancer, with Mohs micrographic surgery (MMS) allowing the highest cure rates, best esthetics and superior functional outcomes. Ear, nose, and throat (ENT) surgeons are often challenged with patients presenting skin cancer, needing appropriate expertise to its adequate management. This paper highlights the most important aspects of MMS, enabling ENT surgeons to become familiar with its fundamental aspects. A review of the literature was performed, concomitantly presenting the author's outcomes as an ENT surgeon. A total of 51 MMSs were performed in 41 patients, and 78.4% of the tumors were cutaneous basal cell carcinomas (cBCCs), 19.6% were cutaneous squamous cell carcinomas (cSCCs), and one case was a microcystic adnexal carcinoma. Most tumors were located in high-risk areas (88.2%), and 84.3% of them were ≥10 mm in diameter. Most tumors (90.2%) required no more than two MMS excision steps to be completely removed. All cases were managed by reconstruction either using flaps or grafts. Recurrence occurred in only 2% of the cases. This study addressed the main issues of MMS, which may be important in ENT surgeons' daily practice.

Abstract	Introduction: Hip fracture in elderly individuals is frequent and is related to a high rate of mortality. Finding the best predictor of death will help to develop better patient care. Aim - To analyze the reliability of the clinical data and assessment scores to predict mortality in acute hip fracture in elderly patients. Patient and methods: Prospective data were collected from all patients > 65 years with acute hip fracture from May to October 2020. The clinical data collected were age, sex, comorbidities, medication, type of fracture and presence of delirium. The assessment scores were ASA, Lee, ACP and Charlson. Results: The statistically significant results were age > 80 years (OR 1.121 IC95% [1.028-1.221] p = 0.0101) and number of medications (OR5.991 95% CI [2.422-14.823] p <0.001). Three scores showed a correlation with mortality: ASA score (p = 0.017), Lee score (p = 0.024) and ACP score (p = 0.013). The Charlson Comorbidity Index did not correlate with mortality (p = 0.172). Conclusion: To stratify the risk of death, both clinical data and scores should be used. The best clinical indicators are age and number of medications, and the scores are ASA, Lee and ACP.
