Berdasarakan penelitian sebelumnya dilaporkan bahwa tipe kandang berpengaruh terhadap produktivitas broiler. Oleh karena itu, penelitian ini bertujuan untuk menghitung kesesuaian kebutuhan kandang semi-closed house dalam menghasilkan kecepatan angin yang sesuai dengan kapasitas kandang. Penelitian ini merupakan penelitian kualitatif dengan pendekatan studi kasus. Subjek penelitian ini adalah 3 peternakan ayam broiler yang menggunakan kandang semi-closed house. Teknik pengumpulan data menggunakan wawancara dan observasi. Analisis data menggunakan model interactive Miles dan Huberman. Hasil penelitian menunjukan bahwa kandang semi-closed house yang telah dievaluasi memiliki material atap yang nilai U-value nya masih diatas standar 0.05-0.04 W/m2˚C, terpal untuk plafond dan dinding yang masih belum rapat sempurna dan dipasang permanen di dinding, nipple drinker yang belum memakai hanger dan water regulator pressure dan terdapat peternak yang belum menggunakan fungsi kontrol sistem yaitu temtron agrologic 340D dan menggantinya dengan menggunakan timer Omron. Pengukuran kapasitas exhaust fan di setiap periode perlu dilakukan karena kemampuan mekanik exhaust fan mengalami penurunan performa seiring berjalannya waktu. Air exchange rate dipengaruhi oleh kemampuan kapasitas total exhaust fan.  Jika nilai air exchange rate <60 detik,  maka akan menimbulkan masalah pada status kesehatan ayam broiler.  Pengukuran velocity (kecepatan anagin) menggunakan Kestrel 3000 menunjukan keseragaman yang baik dengan nilai CV < 35%.

Authors: Salinas Queenie Elyza G. , Tiamzon Bernardita I.
Published: November 2022

Parents’ love is unconditional, truly selfless, and unending. It always protects, always hopes, and is always proud. Parenting life seems to be challenging, but despite all this, having children to nurture and a family to lean on is somehow fulfilling. This study explored the lived experiences of parents of learners with intellectual disabilities. The researcher conducted a virtual face–to–face interview to describe their parenting day–to–day experiences, challenges, and coping mechanisms as parents of learners with intellectual disability. Limitations to examining the phenomenon are observed in this study. Six (6) parents of learners with intellectual disabilities were interviewed virtually, and the data gathered was transcribed using thematic analysis. The themes derived from this study were: Journey to Acceptance, The Art of Being Selfless, and The Key to Successful Co-Parenting. The exploration of themes described meaningfully and inspirationally the parents' journey when raising a child with an intellectual disability. Data gathered was supported by related literature and studies and the theoretical perspectives involving Parent Development Theory (PDT) and Lazarus and Folkman's stress and coping theory. The insights gained in this study will contribute to further parenting studies and special education and general education research. The findings of this study may enlighten parents of learners with intellectual disabilities, special education teachers, general education teachers, social workers, and others in support of awareness advocacy on the wonderful journey of parenting experiences, challenges, and coping mechanisms when raising a child with intellectual disability.

A profissão que exercem os mototaxistas em transportar passageiros/as e vivenciar diariamente um trânsito com milhares de veículos pode causar estresse. Para tanto, o presente artigo teve como objetivo analisar as experiências de estresse dos mototaxistas no Município de Barreiras-BA numa perspectiva Cognitivo-Comportamental. A metodologia utilizada na pesquisa é qualitativa de caráter exploratório. O estudo foi realizado com 5 profissionais (mototaxistas) com idades entre 35 a 50 anos, regularmente cadastrados na Associação dos Proprietários de Mototaxistas no Município de Barreiras-BA. Como instrumentos de coletas de dados, utilizou-se um Questionário Sociodemográfico com 10 perguntas fechadas e abertas e uma Entrevista Semiestruturada com 4 perguntas abertas. Os dados foram analisados através da análise de conteúdo, em seguida transcritos os discursos e construídas as categorias. Os resultados apresentam relatos de estresse associado ao exercício da profissão por parte dos mototaxistas. Os participantes afirmaram vivenciar situações estressantes na profissão, como congestionamentos de veículos e motos no munícipio de Barreiras-BA, motoristas que não respeitam as leis, são apressados, buzinam, desrespeitam e insultam. Além disso, demonstram que a irritabilidade e nervosismo, devidos à renda mensal reduzida afetam nos relacionamentos com familiares e colegas da profissão. Portanto, com a realização deste estudo sugerem-se que se desenvolvam mais pesquisas para explorar este assunto tão pouco discutido no Brasil, elaborando estratégias preventivas de intervenção voltadas para o estresse e oferecendo uma melhor qualidade de vida a esses profissionais.

GRAPHICAL ABSTRACT
Performance Evaluation of Novel Piezoelectric Cantilever Beam Structure for Energy Harvesting
Authors: Tyagi Naveen , Gaur Anshu Mli , Mahajan Aparna N.
Published: November 2022

This study proposes an elastic compact Piezoelectric energy harvester (PEH) in multiple configurations, including a single cantilever beam, a single cantilever beam with a hole, two cantilever beams with a hole contributing towards a wider operating bandwidth. The cantilever beams are designed in multiple structural forms and section shapes, including symmetrical uniform section rectangle frames. Natural frequencies, vibration modes, and output voltages of PEH are estimated using Finite element software, with the frame acting as a rigid body and the cantilever plate acting as a deformed structure. A PEH with a rectangular cantilever plate surrounded by a rigid frame is designed and attached to the vibration platform with a customized fixture in the simulation software. The design meets the requirements of natural frequency and high output voltage in the low-frequency band. The PEH structure is simulated using a variety of piezoelectric materials, primarily PZT4 and PZT5H, barium titanate, lithium niobate, zinc oxide, and polyvinylidene difluoride (PVDF) using the finite element method. In the structural configuration of two cantilever beams with holes, PEH exhibited the maximum output voltage of 32.832 V for Zinc oxide compared to other materials. So, it can be concluded that insertion of hole and variation in the geometry of cantilever structure along with frame plays a vital role in achieving a large voltage from the vibrations in PEH.
HIGHLIGHTS

The finite element approach was used to develop and simulate the cantilever-based piezoelectric energy harvesting structure
Multiple elastic compact Piezoelectric energy harvester (PEH) designs, including a single cantilever plate, a single cantilever plate with a hole, and two cantilever plates with a hole, are simulated using different materials
The frame, hole insertion, and geometry modification of the cantilever structure all play important roles in generating a substantial voltage from the vibrations in PEH
This study presents an Eigen frequency analysis of different PEH structures

Resumo

A enxaqueca ou migrânea, é uma das queixas mais comuns na prática clínica da neurologia. É multifatorial, sendo a insônia um fator de predisposição presente em quase 50% dos casos. A fisiopatologia da migrânea é complexa e envolve alterações em diversas áreas do SNC e que encontram vias comuns com os distúrbios do sono. Entre elas, conexões hipotalâmicas, hormônios e neuropeptídeos, como orexias e monoaminérgicos. Além disso, outros distúrbios do sono específicos se relacionam com a migrânea. Atualmente, o tratamento é individualizado e além de medidas medicamentosas, é proposto mudanças nos hábitos de vida e adequações do sono. Diante disso, é uma oportunidade terapêutica a associação entre sono e enxaqueca e isso pode ser feito com base em uma abordagem clínica detalhada durante a consulta.

Published: November 2022

O uso de derivados da Cannabis sp. no tratamento de certas condições médicas, como dor neuropática, epilepsia e esclerose múltipla já é bem conhecido. Porém, estudos sobre seu benefício em cefaleias ainda são de baixa abrangência, sendo constituídos, em sua maior parte, por relatos e séries de casos. Apresentamos o caso de paciente masculino de 74 anos, portador de enxaqueca de alta frequência (2 a 3 vezes/semana) há vários anos, com importante limitação funcional associada a diversos gatilhos, fazendo uso apenas de triptanos durante as crises. Apresentou intolerância a 2 medicamentos profiláticos (topiramato e propranolol). Realizou 2 aplicações de Erenumabe 70 mg, havendo considerável melhora inicial seguida de novo aumento na frequência das crises após a segunda aplicação, com interrupção do tratamento. Fez uso de nutracêuticos por 6 meses, sem grande melhora. Após introdução de óleo de canabidiol, as crises reduziram em frequência (1 episódio/mês) e intensidade, com intervalo recorde de 30 dias seguidos sem dor, associado a eliminação de gatilhos. Estudos pré-clínicos avaliando a relação entre o sistema endocanabinoide e a fisiopatologia da migrânea apontam para os derivados da Cannabis sp. como potenciais armas para o tratamento dessa condição. No entanto, o papel desses derivados como profilaxia das crises de enxaqueca ainda é especulativo, necessitando de estudos controlados para maior definição.

IntroductionMusculoskeletal disorders in the cervical spine have been increasingly investigated and observed in patients with migraine. One of them is a poorer cervical muscle performance as assessed by the cranio-cervical flexion test (CCFT). In addition, patients with migraine have alterations in the recruitment of muscle motor units observed by surface electromyography during CCFT.
ObjectiveThe aim was to verify if there are differences in the electrical activity and the clinical performance of superficial neck flexors and extensors during the CCFT in women with migraine considering the presence or absence of concomitant neck pain symptoms.
MethodsA total of 100 women were assessed: 25 with migraine without neck pain, 25 with migraine and neck pain, 25 with mechanical neck pain and 25 pain-free control. Clinical and demographic data were collected, The CCFT was performed in all groups. The test assessed the deep flexors muscle by a pressure unit biofeedback placed in the posterior region of the neck and initially inflated to 20 mmHg composed by 5 stages, with increase pressure by 2 mmHg at each stage, reaching 30 mmHg, keeping the pressure for 10 seconds without resorting to compensation. Electromyography data were collected with TrignoTM Wireless System wireless surface sensors. The sensors were firmly attached bilaterally on: sternocleidomastoid (SCM); splenius capitis, anterior scalene and upper trapezius. Electromyographic activity evaluated during the CCFT was normalized by the average the root mean square (RMS) calculated for the reference voluntary contraction and expressed as a percentage. Groups comparisons were performed with non-parametric tests adopting a level of significance of 0.05. To analyze the between-groups differences on the proportion of clinical targeted performance stages reached by each participant within the CCFT, the chi-square (X2) test was calculated, and the data were submitted to a post-hoc proportion test. (To see the complete abstract, please, check out the PDF).

Published: November 2022

IntroductionMigraine is the most common primary headache in medical care, being the cause of migraine in more than 10% of the population, directly impacting the quality of life and working capacity of those affected. Recently, studies have indicated a close association between migraine and anxious and depressive disorders mediated by mechanisms such as alterations in monoamines (serotonin and dopamine) and neurotransmitter peptides such as endorphins and enkephalins, immune dysfunction, and genetic factors, causing symptoms and common characteristics among patients.
ObjectiveInvestigate the association between anxiety and depression with migraine features and accompanying symptoms.
MethodsCross-sectional study based on 466 patients with migraine, which were submitted to a structured interview in which demographic, clinical, anthropometric data and data related to migraine and its characteristics were obtained. Besides that, patients answered validated forms regarding the impact of migraine (HIT-6), allodynia (ASC-12), depression (IDB – inventário de Beck), anxiety (STAI Y-1 and Y-2) and hyperacusis scale. Categorical variables were evaluated using the chi-square test and numerical variables were analyzed using the Mann Whitney test. Statistical difference was considered when p≤0.05.
Results466 patients participated in the study, of which 86.1% were women, the median age was 33 years, 55.5% of the individuals had episodic migraine and 61.8% reported absence of aura. Regarding the patients with anxiety, 93.30% reported association of osmophobia with migraine attack (p=0.03) and 46.70%, association with diarrhea (p=0.001). Patients with anxiety scored higher on the impact of migraine questionnaire (p=0.046), allodynia (p=0.005) and the hyperacusis scale (p=0.029).

Dialysis-related headache: prevalence and clinical features in patients on hemodialysis and after kidney transplantation
Authors: Gomes Bruno Teixeira , Costa Alberto Luiz Cunha da , Mazzali Marilda
Published: November 2022

IntroductionHeadache is a common symptom among patients on hemodialysis, occurring in up to 70%. Dialysis headache is defined by the International Classification of Headache Disorders (ICHD-3) as a headache with no specific characteristics, occurring during and caused by hemodialysis, and which resolves spontaneously within 72 hours after the session has ended. There is no consensus on its pathophysiology or triggering factors.
ObjectiveTo evaluate the prevalence, clinical features and factors associated with dialysis headache in patients with chronic kidney disease on renal replacement therapy.
MethodsCross-sectional observational study with a quantitative approach. Participants were divided into two groups: (1) 25 patients on hemodialysis and (2) 25 patients on early post kidney transplantation. All participants were interviewed with a structured questionnaire, the Hospital Anxiety and Depression Scale, and the Epworth Sleepiness Scale. Blood pressure, weight, urea, glucose and electrolytes were evaluated before and after one hemodialysis session. Control groups were classified within the headache-free patients in each group. Numerical variables were expressed as mean and standard deviation and evaluated using Student's t test (two-tailed) or Mann-Whitney U test. Categorical variables were expressed as percentage and evaluated using Pearson's chi- squared test. The p value was considered statistically significant when lower than 0.05.
ResultsIn group (1), 8 patients (32%) were diagnosed with dialysis headache, predominantly pulsatile (n=6, 75%), accompanied by photophobia (n=6, 75%), phonophobia (n=4, 50%) and nausea or vomiting (n=6, 75%), with a mean pain score of 7.75 ± 1.58. Individuals with headache had higher scores for anxiety (7.00 ± 3.93 vs. 3.82 ± 3.23, p=0.03) and sleepiness (9.13 ± 3.94 vs. 4.76 ± 3, 85, p=0.01).

Assessing the influence of migraine on stroke ischemic penumbra
Authors: Oliveira Felipe Araújo Andrade de , Dourado Filho Mario Genuíno , Rocha-Filho Pedro Augusto Sampaio
Published: November 2022

Abstract
Introduction
There is controversy as to whether migraine affects the behavior of ischemic penumbra during the acute phase of an ischemic stroke, thereby accelerating the formation of cerebral infarction. 
Objectives
To assess whether migraine modifies the existence and volume of the divergence between the areas of diffusion and perfusion in the stroke (the penumbra).
Methods
This was a prospective cohort study carried out in a hospital in the city of Recife, Pernambuco, Brazil. We included consecutively hospitalized patients with ischemic stroke within 72 hours of symptom onset. A diagnosis of ischemic stroke was made by the presence of a diffusion restriction pattern on the MRI within a compatible clinical context. Patients were assessed by a neurologist who conducted an interview using a semi-structured questionnaire containing questions regarding sociodemographic data, the presence and characteristics of headaches in their lives, the presence and characteristics of headaches related to ischemic stroke and the related clinical condition to ischemic stroke. The headaches presented were classified according to the diagnostic criteria of the third edition of the International Classification of Headache Disorders. The National Institute of Health Stroke Scale and the modified Rankin scale were used. Patients underwent MRI of the brain with diffusion and with perfusion. 
Results: A total of 221 patients were included, 59.3% of whom were male, and a mean age of 68.2 ± 13.8 years. Ischemic penumbra analysis was performed in 118 patients. There was no association between migraine and the absence of ischemic penumbra (OR: 1.22; CI95%: 0.52 – 2.87; p=0.649; Chi-Square Test). There was no difference in the volume of ischemic penumbra between those with and without migraine. There was no difference in stroke volume between those with and without migraine (1.0; 0.38 – 7.9 cm3...

Caliber and type of needle are associated with the risk of spontaneously reported post-dural punction headache
Authors: Domingues Renan , Vega Márcio , Giafferi Carlos , Brunale Fernando , Senne Carlos
Published: November 2022

Introduction

Post-dural punction headache (PDH) is defined as an orthostatic headache that develops within the first few days after performing a spinal tap and it is related to extravasation of cerebrospinal fluid (CSF) into the epidural space, resulting in hypovolemia and CSF hypotension. The risk factors for PDH are not yet fully understood. 

Objective

To evaluate the risk of spontaneously reported PDH according to the size and type of spinal tap needle.

Methods

A total of 4589 patients undergoing outpatient lumbar puncture were included. All CSF collections were performed at Senne Liquor Diagnostico, a laboratory specialized in CSF collection and analysis. Patients were instructed to report by telephone the onset of orthostatic headache during the first 7 days after the puncture to the medical team of the laboratory. Patients with previous headache were instructed to report any change in the headache pattern during the same period. 

Needle gauge was classified into two groups: 1) 25G or less and 2) greater than 25G. Two types of needles were used and compared: 1) Pencil point and 2) Quincke. 

Comparisons of the percentages of spontaneous reports of PDH were made using the chi-square test.

Results

141 patients (3.07%) reported PHD to the laboratory's medical team. Needles of 25G gauge or less were used in 31.8% of cases. The percentage of patients reporting PHD in the group of 25G or less needles was 1.9% versus 3.6% in the group of greater than 25G needles (P=0.003). Pencil point needles were used in 10.6% of cases. The percentage of PHD among pencil point group was 1.4% versus 3.2% in Quincke group (P=0.026). 

Conclusion

25G or finer gauge needles as well as pencil point type needles significantly reduced the risk of spontaneously reported PHD.

Introduction
Spontaneous intracranial hypotension (SIH) is a secondary cause of headache often misdiagnosed and underdiagnosed disorder. The main presentation is orthostatic headache. An uncommon symptom is cranial nerve palsy. We described a case of SIH that presented to our service with sixth cranial nerve palsy.
Case Report
Female, 39 years old, no relevant medical past or history of trauma, awoke due intense holocranial headache, associated with vomiting and photophobia, worsening in orthostasis. In the general emergency department, she was release with prescription of analgesics and topiramate, without resolution. After a week, the patient reported diplopia and was referred to our service, a tertiary center. In admission, she kept an intense orthostatic headache and in neurologic examination she presented right sixth nerve palsy, no other deficits. Laboratorial tests were normal, including metabolic and infectious marks. Cerebrospinal fluid (CSF) opening pressure was low (50 mmH2O) and analysis showed elevated protein levels (158mg/dl). MRI showed diffuse pachymeningeal enhancement and venous sinus distension, mainly in superior sagittal venous sinus. CT myelogram detected a spinal CSF leak in transition C1-C2. Initially, performed hydration and bed rest, while patient with partial improvement of headache. An epidural blood patch was then performed using 15ml of autologous blood with compatible contrast and lidocaine. There was complete resolution of pain after the procedure and four weeks later complete resolution of right sixth nerve palsy.
Discussion
According to International Classification of Headaches Disorders, third edition (ICHD-3), the headache attributed to SIH is descripted as a headache has developed in temporal relation to low CSF pressure (<60mm H2O) and/or evidence of CSF leakage on imaging.
