ativismo climático na imprensa portuguesa
Authors: Almeida Cláudia 
Published: July 2022

Nos últimos anos, o movimento social pelo clima português tem vindo a afirmar-se progressivamente no espaço político e mediático. A cobertura mediática é um objetivo intencional procurado pelos movimentos sociais, especialmente devido à sua influência nas representações que permeiam o pensamento coletivo. Devido ao poder que os media têm na criação e consolidação de representações sociais, e face ao conhecimento limitado sobre a cobertura mediática do ativismo climático em contexto nacional, este estudo teve como objetivo avaliar as representações e a contextualização dos ativistas pelo clima na imprensa. Para isto, foi realizada uma análise quantitativa e qualitativa da evolução da cobertura do ativismo climático, dos perfis de representação dos ativistas, e de alguns indicadores de (des)legitimação, tais como os diretamente associados ao paradigma do protesto — nomeadamente a autorrepresentação e o recurso a declarações de figuras de autoridade. A análise de 175 artigos publicados online no jornal PÚBLICO revelou um enquadramento preferencial do ativista, o qual tem frequentemente oportunidade de autorrepresentação. Adicionalmente, e ao contrário do que foi descrito por estudos internacionais, o jornal atribuiu exclusivamente perfis de representação negativa a ativistas estrangeiros e os dados revelaram uma predominância do perfil estudante-ativista, em detrimento de enquadramentos que salientam o incómodo causado pelos ativistas.

Robot lengan merupakan robot yang memiliki fungsi seperti tangan manusia yang dapat membantu mobilisasi khususnya dalam mengambil dan memposisiskan barang. Hal ini dapat membantu aktivitas manusia baik dalam dunia industri maupun kehidupan sehari-hari. Agar dapat diakses oleh manyarakat luas maka diperlukan perancangan robot lengan menggunakan Google assistant untuk memberikan perintah suara, adanya segmentasi warna untuk mendeteksi warna objek, melacak objek, dan inverse kinematics. Robot telah mampu mencapai tingkat keberhasilan 100% dengan waktu rata-rata yang dibutuhkan untuk menyelesaikan misi 28.675 detik. Penggunaan Google assistant mampu menerima perintah dengan tingkat keberhasilan sebesar 96.97% dan error servo 1 sebesar 3.18? dengan akurasi sebesar 97.69%, error servo 2 sebesar 11.99? dengan akurasi sebesar 89.57%, dan error servo 3 sebesar 18.81? dengan akurasi sebesar 88%. Supaya deteksi dapat berjalan dengan lancar maka harus didukung dengan pencahayaan minimum sebesar 100 lux.

Status of Palliative Care Services in Tamil Nadu – A Descriptive Report
Authors: Deenadayalan Sathish Kumar , Veeraiah Surendran , Elangovan Vidhubala , Sathyamurthi K. 
Published: July 2022

Objectives:
Advanced cancer patients attending tertiary cancer centres from rural places are referred back to local physicians for symptom management. Due to lack of networking with palliative care centres (PCCs), the referred patients do not receive appropriate palliative care (PC) services. Hence, an attempt was made to map the PCCs in Tamil Nadu to make the referral system efficient.

Material and Methods:
PCCs in Tamil Nadu were identified from the National Health Mission directory, online sources and from morphine license annexure of drug control department. The details regarding nature of facility, PC model, service type, procedures, cost, morphine availability and type of personnel involved in their PCCs were collected from government and private centres. The data were analysed using descriptive statistics and geomapping of all the centres identified was created.

Results:
A total of 371 PCCs were identified, of which 32 were government headquarter hospitals (GHQH), 281 were government community centres and 58 were private. Eighty-three of the 90 centres (including GHQH and private) were active and 60 responded to the survey. More than half of the centres were hospital-based (61.7%) and 28.3% were community-based. The majority of the PCCs had in-patient (75%) and out-patient (63.3%) facilities and 63.3% had regular home visits. Forty-six centres provide PC service free of cost. Nearly 80% provide morphine for pain management, wherein 41 have obtained a license. In total, ten centres had a social worker and four had a psychologist.

Conclusion:
The number of PCCs is disproportionate, in which majority of the centres are clustered in urban areas. Integrating PC services into the existing health system is the way forward.

Authors: Hatae Ryusuke , Mizoguchi Masahiro , Arimura Koichi , Kiyozawa Daisuke , Shimogawa Takafumi , Sangatsuda Yuhei , Nishimura Ataru , Ono Kotaro , Oda Yoshinao , Yoshimoto Koji 
Published: July 2022

Background:
Angiolipomas are benign mesenchymal tumors comprising mature adipocytes and abnormal blood vessels, commonly found in the subcutaneous tissue of the trunk and rarely in the skull. Furthermore, sporadic cases of angiolipoma with arteriovenous fistula (AVF) have been reported.

Case Description:
We reported the case of a 72-year-old woman who presented with head swelling, seizures, and cognitive dysfunction. Computed tomography and magnetic resonance imaging revealed a right frontal bone tumor exceeding a sagittal suture of up to 10.7 cm. Angiography revealed AVF and varices formation. Endovascular embolization was performed to treat the AVF and reduce blood loss during surgical resection. Two days after the embolization, a craniotomy was performed; however, uncontrollable bleeding was observed at the time of tumor resection. Postoperatively, the patient was symptom-free and has been stable for 2 years without recurrence.

Conclusion:
Despite careful preoperative evaluation and treatment planning, the patient in this case report was difficult to treat. Such cases require adequate preparation.
Is there a limited value of cytoreductive surgery in elderly patients with malignant gliomas?
Authors: Elserius Anne S. L. , Hodson James , Zisakis Athanasios , Ughratdar Ismail 
Published: July 2022

Background:
Glioblastoma (GB) is well known for being the most aggressive primary cerebral malignancy. The peak incidence is at 60–70 years of age, with over half of patients aged over 65 years at diagnosis.

Methods:
Patients with a confirmed histological diagnosis of GB between January 2009 and June 2016 at a single center were retrospectively identified. The inclusion criteria for the study were age over 65 years at diagnosis, and surgical management with either a burr hole biopsy or craniotomy.

Results:
A total of n = 289 patients underwent surgery for GB, with a median age at diagnosis of 71 years, and of whom 64% were male. Craniotomies were performed in 71%, with burr hole biopsies performed in the remainder (29%). Patient survival differed significantly with treatment modality (P < 0.001), ranging from a median of 382 days in those treated with a combination of craniotomy, radiotherapy (RT), and temozolomide (TZM), to 43 days in those only receiving a burr hole biopsy with no further treatment. On multivariable analysis, treatment with RT + TZM was significantly independently associated with longer patient survival (P < 0.001). Craniotomy was associated with a significant improvement in performance status, compared to burr hole biopsy (P = 0.006). For the subgroup of patients receiving TZM, those with a methylated O6-methylguanine-DNA-methyltransferase (MGMT) status had significantly longer overall survival than those with unmethylated MGMT (median: 407 vs. 341 days, P = 0.039).

Conclusion:
Our retrospective data demonstrate that the elderly population with GB benefit from aggressive chemo-RT, regardless of surgical intervention.
