Authors: Gribble Rachael , Mahar Alyson L. , Keeling Mary , Sullivan Kate , McKeown Sandra , Burchill Susan , Fear Nicola T. , Castro Carl A.
Published: August 2020

Introduction: While some families may experience poor mental health, substance use, and poor school performance due to service life, the usefulness and applicability of these research findings may be affected by how representative study participants are of the broader population. This article aims to examine how research on mental health and substance use defines a “military family” to understand if the current body of evidence reflects the increasing diversity of this population. Methods: A systematic search of academic articles was conducted in Ovid MEDLINE, Ovid Embase, Ovid PsycINFO, Ebsco CINAHL and ProQuest PILOTS using database-specific subject headings and keyword searches for ‘military’, ‘family’, ‘mental health’ and ‘substance use’. Sociodemographic and military characteristics of study participants were extracted to identify who was and was not included. Results: The most commonly represented family structure was the traditional, heteronormative family comprised of a male service member married to a female civilian with whom they have children. Military couples without children, dual-serving couples, families of LGBTQ personnel, unmarried and new relationships, single parents, male spouses/partners, Veterans not seeking Veterans Affairs (VA) services, and families with additional challenges were regularly not reflected in the research due to implicit or explicit exclusion from studies. Discussion: Research on mental health and substance use among the family members of service personnel continues to reflect the traditional, heteronormative family. Future studies should consider more inclusive definitions of family and creative approaches to recruitment to ensure research in this area reflects the experiences, needs, and strengths of an increasingly diverse military community.
Evaluation of three abbreviated versions of the PTSD Checklist in Canadian Armed Forces personnel
Authors: Sudom Kerry
Published: August 2020

Introduction: Post-deployment screening within the Canadian Armed Forces (CAF) aims to identify individuals with mental health problems. However, as screening is a time-consuming process, it is important to consider ways to reduce the time required, including the use of shorter scales. The scale currently used to assess posttraumatic stress disorder (PTSD), the PTSD Checklist (PCL-C), is lengthy, although validated shorter versions have been developed that have not yet been evaluated in the CAF population. Methods: Three brief versions of the PCL-C were evaluated in this study: the PCL-2, PCL-4 and PCL-6. The operating characteristics of each scale were examined using the screening and diagnostic cut-offs of the full PCL, as well as clinician ratings of PTSD being of major concern, as the standards for comparison. Optimal cut-offs for each scale were determined based on a combination of sensitivity, specificity, area under the curve (AUC), and prevalence of disorder compared to the full scale. As well, correlations with other measures of health were examined. Results: Although all three scales demonstrated good psychometric properties, the PCL-6 showed the strongest properties of the three scales. Optimal cut-offs were similar to those found in past research when calibrated against the PCL-C screening cut-off for PTSD and to clinician ratings. As well, it exhibited high correlations with other measures of mental health. Discussion: This research provides evidence for the acceptability of brief measures in screening for PTSD in military members following deployment. In particular, it points to the advantages of using the PCL-6, with cut-offs in line with those recommended in past research.

Published: August 2020

Objective: To compare vocal function between females with benign vocal fold lesions, and females with normal voices by use of electroglottograph (EGG), also in addition to determining which EGG parameters were significantly correlated with the perceptual degree of dysphonia. Material and Methods: EGG data were obtained from 32 females with benign vocal fold lesions and 32 females with normal voices. The EGG parameter values were analyzed from their productions of four sustained vowels (/a:/, /u:/, /i:/, and /æ:/). Results: The two perturbation measures of EGG signals, EGG-jitter and EGG-shimmer of females with benign vocal fold lesions were significantly higher than those of normal females at a p-value<0.01 for all four vowels. EGG-SDF0 of females with benign vocal fold lesions were significantly higher than those of normal females at a p-value<0.01 for /i:/, and /æ:/. EGG-F0 of females with benign vocal fold lesions were significantly lower than those of normal females at a p-value<0.01 for /u:/, /i:/, and /æ:/. The differences in contact quotient were non-significant on all four sustained vowels between the two groups. In addition, EGG-SDF0 was found to be significantly correlated with the perceptual degree of dysphonia for four sustained vowels. Conclusion: The results of this study showed the differences between vocal function of females with benign vocal lesions and females with normal voices, using EGG parameters. Furthermore, EGG-SDF0 could be used as an indicator for the degree of severity of dysphonia in females with benign vocal fold lesions.

Authors: Suero Molina Eric , Catalino Michael P. , Laws Edward R.
Published: August 2020

Harvey Cushing is considered the father of neurosurgery, not just for his work within the United States, but also for his global influence through international visitors and trainees. Starting in 1920, the neurosurgical clinic at the Peter Bent Brigham Hospital in Boston, led by Cushing, trained surgeons from all over the globe, many of whom returned home to establish neurosurgical departments and become neurosurgical pioneers themselves. The objective of this vignette is to highlight the importance of Cushing’s international trainees, describe their contributions, and discuss how each had an impact on the development of the practice of neurosurgery worldwide. The authors demonstrate how Cushing provided the impetus for a movement that revolutionized neurology and neurosurgery worldwide. Even today, international cooperation continues to shape the success of our delicate specialty.

Published: August 2020

OBJECTIVE

The aim of this study was to characterize the clinical and electrophysiological findings of epilepsy originating from the orbitofrontal cortex (OFC) as well as its surgical outcomes.

METHODS

The authors retrospectively reviewed 27 consecutive cases of patients with drug-resistant orbitofrontal epilepsy (OFE) who underwent tailored resective surgery after a detailed presurgical workup. Demographic features, seizure semiology, imaging characteristics, resection site, pathological results, and surgical outcomes were analyzed. Patients were categorized according to semiology. The underlying neural network was further explored through quantitative FDG-PET and ictal stereo-electroencephalography (SEEG) analysis at the group level. FDG-PET studies between the semiology group and the control group were compared using a voxel-based independent t-test. Ictal SEEG was quantified by calculating the energy ratio (ER) of high- and low-frequency bands. An ER comparison between the anterior cingulate cortex (ACC) and the amygdala was performed to differentiate seizure spreading patterns in groups with different semiology.

RESULTS

Scalp electroencephalography (EEG) and MRI were inconclusive to a large extent. Patients were categorized into the following 3 semiology groups: the frontal group (n = 14), which included patients with hyperactive automatisms with agitated movements; the temporal group (n = 11), which included patients with oroalimentary or manual automatisms; and the other group (n = 2), which included patients with none of the abovementioned or indistinguishable manifestations. Patients in the frontal and temporal groups (n = 23) or in the frontal group only (n = 14) demonstrated significant hypometabolism mainly across the ipsilateral OFC, ACC, and anterior insula (AI), while patients in the temporal group (n = 9) had hypometabolism only in the OFC and AI. The ER results (n = 15) suggested distinct propagation pathways that allowed us to differentiate between the frontal and temporal groups. Pathologies included focal cortical dysplasia, dysembryoplastic neuroepithelial tumor, cavernous malformation, glial scar, and nonspecific findings. At a minimum follow-up of 12 months, 19 patients (70.4%) were seizure free, and Engel class II, III, and IV outcomes were observed in 4 patients (14.8%), 3 patients (11.1%), and 1 patient (3.7%), respectively.

CONCLUSIONS

The diagnosis of OFE requires careful presurgical evaluation. Based on their electrophysiological and metabolic evidence, the authors propose that varied semiological patterns could be explained by the extent of involvement of a network that includes at least the OFC, ACC, AI, and temporal lobe. Tailored resections for OFE may lead to a good overall outcome.
Transthoracic microsurgical anterior decompression without fusion for ossification of the posterior longitudinal ligament in the thoracic spine
Authors: Ko Seokjin , Bae Junseok , Lee Sang-Ho
Published: August 2020

OBJECTIVE

The authors aimed to analyze outcomes following transthoracic microsurgical anterior decompression of thoracic ossification of the posterior longitudinal ligament (T-OPLL), which was causing myelopathy, and determine the predictive factors for surgical outcomes.

METHODS

Patients who underwent transthoracic microsurgical anterior decompression without fusion for the treatment of T-OPLL from December 2014 to May 2019 were included. Demographic, radiological, and perioperative data and clinical outcomes of 35 patients were analyzed. The modified Japanese Orthopaedic Association (mJOA) score and recovery rate were used to evaluate functional outcomes.

RESULTS

A total of 35 consecutive patients (8 men and 27 women; mean age 52.2 ± 10.8 years) were enrolled in this study, and the mean follow-up period was 65.5 ± 51.9 months. The mean mJOA score significantly improved after surgery (5.9 ± 1.8 vs 8.3 ± 1.5, p < 0.001), with a mean recovery rate of 47.7% ± 24.5%. The visual analog scale (VAS) score significantly improved after surgery (7.3 ± 1.3 vs 4.3 ± 0.7, p < 0.001). The outcome was excellent in 4 patients (11.4%), good in 21 patients (60.0%), fair in 4 patients (11.4%), unchanged in 5 patients (14.3%), and worsened in 1 patient (2.9%). There were 12 cases of CSF leakage, 1 case of epidural hematoma, 1 case of pleural effusion, and 1 case of pneumothorax. Age, preoperative kyphotic angle, anteroposterior length of T-OPLL at the maximally affected level, and mass occupying rate were identified as predictors associated with postoperative outcome. A multivariate regression analysis revealed that age and preoperative kyphotic angle were independent risk factors for postoperative outcomes.

CONCLUSIONS

Transthoracic microsurgical anterior decompression without fusion achieved favorable clinical and radiological outcomes for treating T-OPLL with myelopathy. Patient age and preoperative kyphotic angle were independent risk factors for lower recovery rate.
The Institute for Healthcare Improvement–NeuroPoint Alliance collaboration to decrease length of stay and readmission after lumbar spine fusion: using national registries to design quality improvement protocols

Published: August 2020

OBJECTIVE

National databases collect large amounts of clinical information, yet application of these data can be challenging. The authors present the NeuroPoint Alliance and Institute for Healthcare Improvement (NPA-IHI) program as a novel attempt to create a quality improvement (QI) tool informed through registry data to improve the quality of care delivered. Reducing the length of stay (LOS) and readmission after elective lumbar fusion was chosen as the pilot module.

METHODS

The NPA-IHI program prospectively enrolled patients undergoing elective 1- to 3-level lumbar fusions across 8 institutions. A three-pronged approach was taken that included the following phases: 1) Research Phase, 2) Development Phase, and 3) Implementation Phase. Primary outcomes were LOS and readmission. From January to June 2017, a learning system was created utilizing monthly conference calls, weekly data submission, and continuous refinement of the proposed QI tool. Nonparametric tests were used to assess the impact of the QI intervention.

RESULTS

The novel QI tool included the following three areas of intervention: 1) preoperative discharge assessment (location, date, and instructions), 2) inpatient changes (LOS rounding checklist, daily huddle, and pain assessments), and 3) postdischarge calls (pain, primary care follow-up, and satisfaction). A total of 209 patients were enrolled, and the most common procedure was a posterior laminectomy/fusion (60.2%). Seven patients (3.3%) were readmitted during the study period. Preoperative discharge planning was completed for 129 patients (61.7%). A shorter median LOS was seen in those with a known preoperative discharge date (67 vs 80 hours, p = 0.018) and clear discharge instructions (71 vs 81 hours, p = 0.030). Patients with a known preoperative discharge plan also reported significantly increased satisfaction (8.0 vs 7.0, p = 0.028), and patients with increased discharge readiness (scale 0–10) also reported higher satisfaction (r = 0.474, p < 0.001). Those receiving postdischarge calls (76%) had a significantly shorter LOS than those without postdischarge calls (75 vs 99 hours, p = 0.020), although no significant relationship was seen between postdischarge calls and readmission (p = 0.342).

CONCLUSIONS

The NPA-IHI program showed that preoperative discharge planning and postdischarge calls have the potential to reduce LOS and improve satisfaction after elective lumbar fusion. It is our hope that neurosurgical providers can recognize how registries can be used to both develop and implement a QI tool and appreciate the importance of QI implementation as a separate process from data collection/analysis.
Neurological events due to pedicle screw malpositioning with lateral fluoroscopy–guided pedicle screw insertion
Authors: Caelers Inge J. M. H. , Rijkers Kim , van Kuijk Sander M. J. , van Santbrink Henk , de Bie Rob A. , van Hemert Wouter L. W.
Published: August 2020

OBJECTIVE

The risk of novel postoperative neurological events due to pedicle screw malpositioning in lumbar fusion surgery is minimized by using one of the several image-guided techniques for pedicle screw insertion. These techniques for guided screw insertion range from intraoperative fluoroscopy to intraoperative navigation. A practical technique consists of anatomical identification of the screw entry point followed by lateral fluoroscopy used for guidance during insertion of the screw. This technique is available in most clinics and is less expensive than intraoperative navigation. However, the safety of lateral fluoroscopy–guided pedicle screw placement with regard to novel postoperative neurological events due to screw malposition has been addressed only rarely in the literature. In this study the authors aimed to determine the rate of novel postoperative neurological events due to intraoperative and postoperatively established screw malpositioning during lateral fluoroscopy–assisted screw insertion.

METHODS

Included patients underwent lateral fluoroscopy–assisted lumbosacral screw insertion between January 2012 and August 2017. The occurrence of novel postoperative neurological events was analyzed from patient files. In case of an event, surgical reports were screened for the occurrence of intraoperative screw malposition. Furthermore, postoperative CT scans were analyzed to identify and describe possible screw malposition.

RESULTS

In total, 246 patients with 1079 screws were included. Novel postoperative neurological events were present in 36 patients (14.6%). In 8 of these 36 patients (3.25% of the total study population), the neurological events could be directly attributed to screw malposition. Screw malpositioning was caused either by problematic screw insertion with immediate screw correction (4 patients) or by malpositioned screws for which the malposition was established postoperatively using CT scans (4 patients). Three patients with screw malposition underwent revision surgery without subsequent symptom relief.

CONCLUSIONS

Lateral fluoroscopy–assisted lumbosacral screw placement results in low rates of novel postoperative neurological events caused by screw malposition. In the majority of patients suffering from novel postoperative neurological events, these events could not be attributed to screw malpositioning, but rather were due to postoperative neurapraxia of peripheral nerves, neuropathy, or intraoperative traction of nerve roots.

Published: August 2020

OBJECTIVE

Various surgical treatments have been reported for vertebral pseudarthrosis after osteoporotic vertebral fracture (OVF). However, the outcomes are not always good. The authors now have some experience with combined anterior-posterior short-segment spinal fusion (1 level above and 1 level below the fracture) using a wide-foot-plate expandable cage. Here, they report their surgical outcomes with this procedure.

METHODS

Between June 2016 and August 2018, 16 consecutive patients (4 male and 12 female; mean age 75.1 years) underwent short-segment spinal fusion for vertebral pseudarthrosis or delayed collapse after OVF. The mean observation period was 20.1 months. The level of the fractured vertebra was T12 in 4 patients, L1 in 3, L2 in 4, L3 in 3, and L4 in 2. Clinical outcomes were assessed using the lumbar Japanese Orthopaedic Association (JOA) scale and 100-mm visual analog scale for low-back pain. Local kyphotic angle, intervertebral height, bone union rate, and instrumentation-related adverse events were investigated as imaging outcomes. The data were analyzed using the Wilcoxon signed-rank test.

RESULTS

The mean operating time was 334.3 minutes (range 256–517 minutes), and the mean blood loss was 424.9 ml (range 30–1320 ml). The only perioperative complication was a superficial infection of the posterior wound that was cured by irrigation. The lumbar JOA score and visual analog scale value improved from 11.2 and 58.8 mm preoperatively to 20.6 and 18.6 mm postoperatively, respectively. The mean local kyphotic angle and mean intervertebral height were 22.6° and 28.0 mm, respectively, before surgery, −1.5° and 40.5 mm immediately after surgery, and 7.0° and 37.1 mm at the final observation. Significant improvement was observed in both parameters immediately after surgery and at the final observation when compared with the preoperative values. Intraoperative endplate injury occurred in 8 cases, and progression of cage subsidence of 5 mm or more was observed in 2 of these cases. Proximal junctional kyphosis was observed in 2 cases. There were no cases of screw loosening. No cases required reoperation due to instrument-related adverse events. Bone union was observed in all 14 cases that had CT evaluation.

CONCLUSIONS

This short-segment fusion procedure is relatively minimally invasive, and local reconstruction and bone fusion have been achieved. This procedure is considered to be attempted for the surgical treatment of osteoporotic vertebral pseudarthrosis after OVF.
TWISTED COSMIC WEB AS THE ORIGIN OF SPIRAL STRUCTURE IN DISK GALAXIES
Authors: Yurin D. , Kalambay M. , Ibraimova A. , Mahmet H. , Makukov M.
Published: August 2020

The origin of spiral arms is one of the intriguing problems of modern galactic dynamics. Despite decades of research and routine reproducibility in computer simulations, the phenomenon of the spiral arms in disk galaxies remains not fully understood and is a real challenge in modern astrophysics. None of existing theories can give a comprehensive explanation of this phenomena for isolated disk galaxies. These theories successfully explain some elements of the spiral arms formation process, but fail to explain other key elements. We argue that this may hint at the existence of some more general mechanism for the formation of spirals, which embraces the existing theories as distinct components. We propose a draft idea of such theory and discuss how it might be verified.

Published: August 2020

Background:

Previous studies suggest that Dickkopf-1 (DKK1), an inhibitor of Wnt signaling, plays a role in amyloid-induced toxicity and hence Alzheimer’s disease (AD). However, the effect of DKK1 expression on protein expression, and whether such proteins are altered in disease, is unknown.

Objective:

We aim to test whether DKK1 induced protein signature obtained in vitro were associated with markers of AD pathology as used in the amyloid/tau/neurodegeneration (ATN) framework as well as with clinical outcomes.

Methods:

We first overexpressed DKK1 in HEK293A cells and quantified 1,128 proteins in cell lysates using aptamer capture arrays (SomaScan) to obtain a protein signature induced by DKK1. We then used the same assay to measure the DKK1-signature proteins in human plasma in two large cohorts, EMIF ( n = 785) and ANM ( n = 677).

Results:

We identified a 100-protein signature induced by DKK1 in vitro. Subsets of proteins, along with age and apolipoprotein E ɛ4 genotype distinguished amyloid pathology (A + T–N–, A+T+N–, A+T–N+, and A+T+N+) from no AD pathology (A–T–N–) with an area under the curve of 0.72, 0.81, 0.88, and 0.85, respectively. Furthermore, we found that some signature proteins (e.g., Complement C3 and albumin) were associated with cognitive score and AD diagnosis in both cohorts.

Conclusions:

Our results add further evidence for a role of DKK regulation of Wnt signaling in AD and suggest that DKK1 induced signature proteins obtained in vitro could reflect theATNframework as well as predict disease severity and progression in vivo.
Magnet eddy-current losses reduction of an axial-flux in-wheel motor with amorphous magnet metal
Authors: Li Tao , Zhang Youtong , Liang Yuxiu , Yang Ye , Jiao Jie
Published: August 2020

The yokeless and segmented armature axial-flux in-wheel motor with amorphous magnet metal (AMM) stator segment has the advantage of low iron losses, but its open-slot structure causes high eddy-current losses of the permanent magnet (PM), which reduces the efficiency and reliability of the in-wheel motor. To avoid the demagnetization caused by the heat generated by PM losses, the mechanism of PM eddy-current losses reduction for the axial-flux in-wheel motor is revealed by the calculation model. In this paper, the time-step three-dimensional finite-element method (3-D FEM) is used to analyze the PM eddy-current loss caused by slotting effects, spatial harmonics, and time harmonics at different speeds. The effect of PM skewing, PM segmentation, and soft magnetic composite (SMC) layer inserted on the top of PM on eddy-current losses are compared. These methods cannot simultaneously meet the requirements of PM losses reduction and the electromagnetic performance of the motor. A novel combined stator segment with the SMC brim arranged on the top of the AMM stator teeth is proposed to improve the amplitude and distribution of the PM eddy-current density. The analysis results show that the combined stator segment can significantly reduce the PM eddy-current loss and improve the electromagnetic performance of the in-wheel motor.
Electromagnetic torque control for six-phase induction motor expelled continuously variable transmission clumped system using sage dynamic control system
Authors: Chen Der-Fa , Cheng An-Bang , Chiu Shen-Pao-Chi , Ting Jung-Chu
Published: August 2020

The continuously variable transmission (CVT) clumped system with lots of nonlinear uncertainties operated by the six-phase induction motor (SIM) is lacking in good control performance for using the linear control. In light of good ability of learning for nonlinear uncertainties, the sage dynamic control system using mixed modified recurrent Rogers–Szego polynomials neural network (MMRRSPNN) control and revised grey wolf optimization (RGWO) with two adjusted factors is proposed to acquire better control performance. The MMRRSPNN control and RGWO with two adjusted factors can execute intendant control, modified recurrent Rogers–Szego polynomials neural network (MRRSPNN) control with a fitted learning rule, and repay control with an evaluated rule. In addition, in the light of the Lyapunov stability theorem, the fitted learning rule in the MRRSPNN and the evaluated rule of the repay control are founded. Besides, the RGWO with two adjusted factors yields two changeable learning rates for two weights parameters to find two optimal values and to speed-up convergence of two weights parameters. Experimental results in comparisons with those control systems are demonstrated to confirm that the proposed control system can achieve better control performance.
Application of chirp pulse compression technique to a high-temperature EMAT with a large lift-off

Published: August 2020

The interest in applying non-destructive testing to the examination of the flaw and measurement of the thickness in the metals at high temperatures is increasing as the metal processing becomes continuous. Based on this background, we designed a water-cooled shear wave Electromagnetic Acoustic Transducer (EMAT) with a surface cooling technique, and the conversion efficiency could be improved by surface cooling. We used the chirp pulse compression technique to process the raw ultrasonic wave signal without synchronous average. Besides, a large casting slab with coarse grains and a massive forging with high temperatures were chosen as the testing objects. Then, the effect of the lift-off distance on the Signal-to-Noise Ratio (SNR) of ultrasonic signals from the EMATs operated in both the pulse-echo mode and pitch-catch mode was investigated. Subsequently, the ultrasonic signals were de-noised respectively by synchronous averages and pulse compression, and the noise reduction ability was compared. Finally, the EMAT was tested with the forging at different temperatures from 92 °C to 730 °C. The performance of the EMAT with the excitation of a tone-burst signal was also compared with the performance of the EMAT using pulse compression technique. Results show that the lift-off, SNR, range resolution, and inspection efficiency can be largely enhanced with the signal processing of chirp pulse compression to the ultrasonic wave signal with no synchronous averaging. When the forging’s temperature is 730 °C, the SNR of the compressed signal is comparable to the SNR of the signal processed with 64 synchronous averages, and the wave-packet duration can be reduced by 80.5%. The proposed EMAT detection technique is particularly suited for real-time measurement and high-temperature testing.

Os mapas são utilizados para visualização de informações espaciais, auxiliando a percepção das relações humanas com o espaço geográfico, ao passo que permitem a aquisição de distâncias, direções e áreas na visualização geográfica. Fortaleza, conforme dados de órgãos internacionais de 2017, é uma das cidades mais violentas do mundo e o mapeamento criminal pode construir-se como uma ferramenta fundamental para o planejamento do policiamento das cidades, com a produção de imagens que aparecem desde mapas de alfinetes a modernos sistemas de informação geográfica (SIG). Nesse sentido, o objetivo deste trabalho foi analisar as estatísticas sobre a violência dentro do Campus da Universidade Federal do Ceará (UFC) e no bairro Pici, em Fortaleza-CE, no primeiro semestre do ano de 2016, utilizando os dados oficiais da empresa que presta serviços de segurança para a universidade e as estatísticas oficiais do Governo do Estado para o bairro no mesmo período. Ademais, de modo complementar, foi feito um mapa colaborativo com dados do mesmo período do Campus (predominantemente de alunos), utilizando-se de ferramentas das plataformas Google My Maps e Google Earth Pro. A pesquisa revelou que o Campus do Pici não se configura como uma área isolada do restante da cidade de Fortaleza em relação à violência, hipótese inicial deste estudo, uma vez que foram observados ali diversos registros de crimes, inclusive com armas. Por fim, foram feitas sugestões para aprimorar a segurança do Campus, com suporte nas reflexões feitas neste estudo e de informações do site da Pró-Reitoria de Administração da UFC.

Este estudo buscou ressaltar a importância das rodas de conversa na promoção e prevenção em saúde de gestantes e puérperas, bem como foi possível entrelaçar o saber científico com o saber popular, permitindo uma troca de conhecimentos acerca das temáticas abordadas com as gestantes. Os membros do Projeto de Extensão saíram do papel de detentores do saber, o que favoreceu a discussão e fortaleceu o vínculo entre usuários e UBS, permitindo a construção de um conhecimento que vincula teoria e prática. Portanto, as experiências vivenciadas nas rodas de conversas foram fundamentais para o aprendizado, pois consolidaram as práticas de educação e promoção em saúde.

O grupo de puericultura constitui uma estratégia de ampliação da promoção e prevenção da saúde da criança, oportunizando a qualificação da assistência e o desenvolvimento de atividades educativas com mães. Objetivou-se relatar a experiência de acadêmicos de enfermagem na reativação de grupo de puericultura coletiva de um Centro de Saúde da Família (CSF) de um município do interior do estado Ceará. Trata-se de um relato de experiência, referente às atividades de extensão desenvolvidas por acadêmicos de enfermagem da Universidade Estadual Vale do Acaraú, no período de junho a agosto de 2019. Estas atividades tiveram como objetivo contribuir para melhoria da qualidade dos serviços voltados à promoção da saúde materno-infantil. Utilizou-se o modelo de planejamento em saúde proposto por Imperatori & Giraldes (1993), constituído de três etapas: Elaboração do Plano; Execução e Avaliação, a partir do qual elaborou-se como intervenção comunitária a reativação de um grupo de puericultura coletiva. Foram realizadas atividades educativas com as mães, baseando-se nos princípios de Paulo Freire (2011), abordando temas como: desenvolvimento psicomotor da criança; prevenção de acidentes e primeiros socorros; crescimento, desenvolvimento e hábitos de vida saudáveis. A reativação do grupo de puericultura coletiva se mostrou uma estratégia efetiva na ampliação da atenção à saúde das crianças adscritas à unidade saúde, sendo também um espaço de diálogo, esclarecimento de dúvidas, troca de experiências e saberes com as mães. Além disso, proporcionou aos acadêmicos o aprimoramento de competências e habilidades, e conhecimentos a respeito da assistência à saúde da criança.

O presente artigo tem como objetivo comparar as condições de saúde bucal de idosos residentes em uma Instituição de Longa Permanência para Idosos no município de Fortaleza, Ceará (G1), com idosos não institucionalizados (G2). Foram obtidos dados sociodemográficos e realizados exames intrabucais para avaliar as condições: cárie dentária, doença periodontal, edentulismo e uso/necessidade de próteses dentárias. Os dados foram analisados através do software SPSS (Statistical Package for Social Sciences), versão 22.0 através de testes estatísticos apropriados. Diferença significativa foi observada no índice CPO-D, cuja média foi de 28,4 entre o G1 e 24,1 entre o G2 (P=0,02). A ocorrência de cálculo dentário, sangramento gengival e bolsa periodontal foi semelhante entre os grupos. A porcentagem de indivíduos desdentados totais foi de 33,3%, sendo em sua maioria do G1.  Já em relação ao uso e necessidade de próteses dentárias, o G1 utilizava mais e necessitava mais de uma nova prótese total. Já entre o G2, a maior necessidade foi de uma reabilitação oral parcial, mas em contrapartida, o uso de próteses foi menor. Conclui-se que G1 teve uma saúde bucal mais precária em comparação a G2, caracterizada por maior número de dentes perdidos, carecendo de medidas de promoção e recuperação de saúde bucal.
ASSESSORIA TÉCNICA PARA MORADIAS AUTOCONSTRUÍDAS NO SERTÃO CENTRAL CEARENSE
Authors: Máximo Rérisson
Published: August 2020

As imensas necessidades habitacionais brasileiras evidenciam um grave problema social que pode ser classificado em dois componentes principais: o déficit habitacional e a inadequação habitacional. Neste componente estão inseridas as moradias autoconstruídas que não proporcionam condições desejáveis de habitação e representam a maior parte das edificações residenciais produzidas no Brasil. Localizada no sertão central cearense, Quixadá não difere dessa realidade presente tanto em metrópoles quanto em cidades pequenas, ao apresentar déficit habitacional cujo destaque é a inadequação habitacional. Diante deste quadro, criou-se o Escritório Modelo de Assessoria Técnica em Construção Civil, projeto de extensão vinculado ao Instituto Federal do Ceará que atende grupos ou organizações sociais com limitações no acesso a profissionais técnicos na área de construção civil. O projeto possibilita que tal população reforme ou construa suas moradias contando com assistência técnica gratuita, baseando-se na chamada Lei da Assistência Técnica. Ao mesmo tempo, possibilita que alunos tenham uma experiência prática e voltada para questões sociais. Dentre os principais resultados alcançados até o momento destacam-se o desenvolvimento de desenhos e orientações técnicas para duas comunidades na periferia de Quixadá.

Authors: Halim Hasniati
Published: August 2020

ABSTRAK Manajemen Hotel Malya saat ini melakukan repositioning dengan menambah segmen market baru yaitu MICE business (Meeting, Incentive, Convention and Exhibition), sehingga diperlukan suatu upaya untuk memahami  karakteristik pelangggan MICE tersebut dengan cara mengetahui besarnya pengaruh atribut produk terhadap sikap pelanggan corporate meeting di Hotel Malya Bandung. Analisis kuantitatif berupa analisis jalur dipergunakan untuk menghitung besarnya pengaruh atribut produk terhadap sikap pembelian pelanggan. Teknik pengumpulan data menggunakan teknik sensus dengan alat bantu kuestioner disebarkan kepada 50 perusahaan yang telah menyelenggarakan corporate meeting di hotel Malya pada periode tertentu, dengan menggunakan teknik judgment sampling. Hasil penelitian dan pengujian hipotesis pengaruh atribut produk terhadap sikap pembelian pelanggan dapat disimpulkan bahwa hanya People (X3) yang berpengaruh signifikan secara langsung terhadap sikap pembelian yaitu sebesar 35,40%. Pengaruh Physical Evidence (X1) dan Process (X2) tidak berpengaruh signifikan terhadap  sikap pembelian, namun berpengaruh tidak langsung melalui People (X3) yaitu sebesar 24.14%. Sedangkan pengaruh lain terhadap sikap pelanggan yang tidak dipergunakan dalam penelitian ini yaitu sebesar 40,46%. Dapat disimpulkan pula bahwa setiap perusahaan memiliki Unit Buying Center yang terbentuk secara informal tidak terstruktur dan sangat dinamis karena peran masing-masing orang dalam buying center berubah-ubah, hal ini menyebabkan pemasar perlu membuat strategi promosi yang efektif melalui aktifitas sales call (personal selling) yang tepat, sehingga manajemen perlu mengetahui aturan main yang diberlakukan ke masing-masing konsumen perusahaan untuk menggunakan pendekatan yang tepat. Kata Kunci :   sikap pelanggan organisasi, atribut produk, physical evidence, proses,                                orang, afektif, kepuasan

Introduction: Urogenital infections are usually seen during pregnancy and considered as an important cause of preterm labour. Preterm labour is the one of the foremost reason of neonatal morbidity and mortality. Bacterial vaginosis (BV), vulvovaginal candidiasis (VC), and trichomoniasis are responsible for near about 90% of cases of infectious conditions which can lead to eventually gynecological and obstetrical complications such as preterm labour, pelvic inflammatory disease, post-abortion endometritis and chorioamnionitis. Most common infection among women in preterm labour is BV.  This study was conducted to find the association between urogenital infections and preterm labour and also to find out prevalence of urogenital infections in preterm and full term labour.

Method: It was an observational study done in the Department of obstetrics and gynecology IGMC Shimla H.P. from 1st August 2017 to 31st July 2018. A total of 200 women were observed for urogenital infections and their association with preterm labour. Case Group I included 100 women with preterm labour after 24 weeks and before 37 completed weeks of gestation with or without rupture of membranes. Control Group II included 100 women at completed or more than 37 weeks of gestation with no history of preterm labour, matched to the case group with respect to age and parity. Midstream urine was sent for microscopic examination and culture sensitivity. Samples were taken for microbiological study from posterior fornix of vagina. These were studied for microscopic examinations along with Culture sensitivity by standard methods and saline wet mount for BV, VC, Tricomoniasis.

Results: In present study, overall 18% urogenital infection was observed. Statistical analysis reveals that there was association in high vaginal swab, urine culture and both culture positivities.

Conclusion: We concluded that in our study, urogenital infection was more common in women with preterm labour compared to those in full term labour patients group which indicates a significant association of urogenital infections in preterm labour.
