Published: July 2023

Feline panleukopenia (FPL) is a highly contagious acute infectious disease caused by feline parvovirus (FPV). FPV has also been found in giant pandas with clinical signs of vomiting and mild diarrhea, posing a threat to this vulnerable species. Cleaning and disinfection may be one of the most efficacious ways to prevent FPV spread in the habitat of giant pandas. This study evaluated the inactivation effect of peracetic acid (PAA), povidone-iodine (PVP-I), glutaral and deciquam solution (JM) and Virkon S. The tissue culture infective dose (TCID50) assay indicated that the virus may be totally inactivated by JM, PAA and Virkon S. Meanwhile, the hemagglutination (HA) assay showed a high inactivation efficiency of PAA and Virkon S. The analysis of Western blot revealed that PAA, Virkon S and JM can inhibit the structural protein synthesis. Taken together, our findings demonstrated that PAA could rapidly and efficiently inactivate FPV, representing an efficacious disinfectant for FPV control.

Antimony tin oxide (Sb2O5/SnO2) is effective in the absorption of infrared radiation for applications, such as skylights. As a nanoparticle (NP), it can be incorporated into films or sheets providing infrared radiation attenuation while allowing for a transparent final product. The acute toxicity exerted by commercial Sb2O5/SnO2 (ATO) NPs was studied in adults and embryos of zebrafish (Danio rerio). Our results suggest that these NPs do not induce an acute toxicity in zebrafish, either adults or embryos. However, some sub-lethal parameters were altered: heart rate and spontaneous movements. Finally, the possible bioaccumulation of these NPs in the aquacultured marine mussel Mytilus sp. was studied. A quantitative analysis was performed using single particle inductively coupled plasma mass spectrometry (sp-ICP-MS). The results indicated that, despite being scarce (2.31 × 106 ± 9.05 × 105 NPs/g), there is some accumulation of the ATO NPs in the mussel. In conclusion, commercial ATO NPs seem to be quite innocuous to aquatic organisms; however, the fact that some of the developmental parameters in zebrafish embryos are altered should be considered for further investigation. More in-depth analysis of these NPs transformations in the digestive tract of humans is needed to assess whether their accumulation in mussels presents an actual risk to humans.

Published: July 2023

The three-dimensional reconstruction of high-gloss/reflection and low-texture objects (e.g., oil casing threads) is a complex task. In this paper, we present a novel approach that combines convolutional neural networks (CNNs) and multi-layer perception (MLP) with traditional three-dimensional reconstruction methods, thereby enhancing the detection efficiency. Our method utilizes a dataset of 800 samples that includes a variety of thread defects to train a U-net-like model as a three-dimensional reconstructor. Then, an MLP model is proposed to improve the accuracy of the three-dimensional reconstructed thread profile to the level of three-coordinate measurements through a regression analysis. The experimental results demonstrate that the method can effectively detect the black-crested threads of oil casing threads and quantify their proportions in the entire sample for accurate quality assessment. The method is easy to operate and can detect black threads effectively, providing a powerful tool for oil companies to ensure exploration benefits.

The inhalation of natural nanoparticles (NPs) emitted from volcanic activity may be a risk to human health. However, the literature rarely reports the fate and response of NPs once in contact with lung fluids. In this work, we studied the particle size distribution of ashfall from Popocatépetl volcano, Mexico. The collected ashes (n = 5) were analyzed with scanning electron microscopy (SEM) to obtain the elemental composition and morphology, and to determine the size of the ash particles using ParticleMetric software (PMS). The PMS reported most of the ash to have submicrometric size (<1 μm) and an average equivalent circle of 2.72 μm. Moreover, to our knowledge, this study investigated for the first time the behavior of ash NPs at different times (0 to 24 h) while in contact with in vitro lung fluid, Gamble Solution (GS) and Artificial Lysosomal Fluid (ALF) using dynamic light scattering (DLS). We found a large variability in the hydrodynamic diameter, with values less than 1 nm and greater than 5 μm. Furthermore, aggregation and disaggregation processes were recognized in GS and ALF, respectively. The results of this study increase the knowledge of the interaction between NPs and lung fluids, particularly within the alveolar macrophage region.

Published: July 2023

According to the trade association PlasticEurope, global plastics production increased to 390.7 million tons in 2021. Unfortunately, the majority of produced plastics eventually end up as waste in the ocean or on land. Since synthetic plastics are not fully biodegradable, they tend to persist in natural environments and transform into micro- and nanoplastic particles due to fragmentation. The presence of nanoplastics in air, water, and food causes ecotoxicological issues and leads to human exposure. One of the main concerns is their genotoxic potential. Therefore, this study aimed to evaluate the internalization rates, cytotoxicity, and genotoxicity of polystyrene nanoparticles (PS-NPs) in human peripheral blood mononuclear cells (PBMCs) in vitro. The uptake of PS-NPs was confirmed with flow cytometry light scattering analysis. None of the tested nanoparticle concentrations had a cytotoxic effect on human PBMCs, as evaluated by a dual ethidium bromide/acridine orange staining technique. However, an alkaline comet assay results revealed a significant increase in the levels of primary DNA damage after 24 h of exposure to PS-NPs in a dose-dependent manner. Moreover, all tested PS-NPs concentrations induced a significant amount of micronucleated cells, as well. The results of this study revealed the genotoxic potential of commercially manufactured polystyrene nanoparticles and highlighted the need for more studies with naturally occurring plastic NPs.
Experiences and Lessons of Ethics Committee in an Educational Hospital
Authors: PARK Seok Gun , CHEONG Yoo-Seock
Published: July 2023

We discuss our experience and learning of ethics committee in one education hospital. When it was first introduced in 1996, hospital ethics committee was something like a paper committee without action and without power. In 1998, there was a legal affair which accused and sentenced physicians as murderers who discharged the patient according to the request of his wife. This extrinsic pressure from legal system forced the hospital to activate and reform the ethics committee. The leadership of new secretary of the committee played as intrinsic thrust. Lawyer, law school professor, head of nursing department were recruited as new members of ethics committee. Rules for ethics committee were amended at second meeting. The hospital ethics creed was made at third meeting. After fourth meeting, which was released on air by TV broadcasting, two informal consultation was made to secretary. Ethical problems arising in medical practice are not likely to decrease nor become simple in the future. Ethical committee should be prepared to take this responsibility.
Ethical Considerations on Physicians’ Strike in Korea
Authors: CHEONG Yoo-seock , CHO Hyeon-a , PARK Seok-gun , PARK Jae-hyun
Published: July 2023

In August 2000, Korean government implemented a policy to separate the roles of physicians and pharmacists with respect to the prescription and dispensation of medicine. In particular, the policy prohibited physicians from dispensing medicine and prohibited pharmacists from prescribing medicine. Physicians in Korea have been strongly opposed to this policy and have protested its implementation by staging two nation-wide strikes, one immediately prior to the implementation of this policy, and one immediately subsequent to its implementation. These strikes have in turn evoked a hostile response from Korean citizens, who regard the physicians as acting from purely selfish motives. Within this context a debate has been initiated on the ethics of physicians strikes. At the heart of this debate is the following question: Are physicians strikes an ethically acceptable means of protesting government policies?
The purpose of this paper is to evaluate the arguments that have been given on both sides of this debate and to show that physicians strikes are justified from a social and professional point of view.
In this paper, we consider physicians strikes from the point of view of social ethics, professional ethics, and the four principles governing biomedical ethics. We argue that while such strikes can not be justified by the principles of beneficence, non-maleficence, or patients autonomy, physicians do have social and professional responsibilities to protest government policies that are harmful to society and that physicians, strikes that are carried out with this purpose can be justified by the principle of justice. Since this is the ultimate purpose of the strikes recently carried out by the physicians in Korea, we argue that these strikes are justified from a social and professional point of view. Although the strike is justified according our conditions, physicians should not give up patients lives. During the strikes, physicians never stop providing care in the emergency room, ICU(intensive care unit) and to obstetric patients, and they tried not to delay surgeries of critical cancer patients.
Professional Medical Ethics in the Cultural Context of Korea
Authors: KANG Shin-Ik
Published: July 2023

Korean medical society has been in a big turmoil since the second part of the 1990s. The first impetus for this turmoil was given by a court rule against doctors who discharged critically injured patient and removed life-sustaining appliances following the request of the patient's wife. Other members of the family filed a law suit against the doctors and the wife, and they have become convicted murderers according to the criminal law.
When the debate began to subside, another big trouble broke out. The government tried to implement the policy of division between prescription and preparation of drugs in the year 2000. Physicians regarded this policy as another attack on their professional autonomy and interest. To everyone's surprise they went on a strike.
The third impact on the already confounded situation was the report that a team of Korean scientists has cloned human embryos by somatic cell nucleus transfer and extracted stem cells for the first time in the world.
I argue that the three cases have been and will be the paradigm cases for the moral discourse in Korean health care field. Although the nature of the problems are not that different from the cases of the west, the way of discussion and the context of it is not be the same. Korean people have the tradition of emphasizing virtuous doctors embodying good human nature (德醫) rather than the specific medical virtues(醫德) they have.
Virtuous doctors are the medical professionals who not only listen to the voices of patients but also deeply tune into the concrete situation of the people suffering from various problems. This kind of committment to the people coincides with the spirit of the medical professionalism and "thick" version of virtue ethics developed in the west. All these are the moral resources we can mobilize to make a moral contract of our own.
Legal and Ethical Considerations on the Brain Death Decision Committee
Authors: UM Young-Rhan
Published: July 2023

Most transplantation has been done by donation from living donors rather than dead in Korea. Lack of organs is also a big problem. It is said that the Human Organ Transplantation Law is an obstacle to harvest organs from dead people. The author tries to show limits and ethical considerations of the brain death decision committee of the Human Organ Transplantation Law.
The limits are;
1. The roles of committee are overlapped as deciding brain death and assuring ethical affairs.
2. The committee causes a delay of harvesting organs from donors, so donors should endure unnecessary procedures such as medication keeping respiration and heart function.
3. In the law, family member and physician can request for the decision of brain death. Before this, it is important to confirm the will of donor.
The author suggests for the above limits;
1. To devide roles of the committee into two. One is for physicians to decide brain death finally, the other is for ethic committee to examine ethical affairs such as assuring donor's will for donation.
2. To adjust the time of the committee meeting between the first and the second brain death examination.
3. To strengthen assuring the will of donor's for organ donation. For this, chances for expressing donation should be expended before losing competency.
What Is Needed Prior to Respect for Self-determination: Reflections on Physician-assisted Suicide and the Withholding or Withdrawal of Life-sustaining Treatment
Authors: CHOI Kyungsuk
Published: July 2023

In this article I review Koh YS’s recent article concerning the legalization of physician-assisted suicide and provide additional support for the arguments he advances. Koh argues against the legalization of physican-assisted suicide and for an extension of the period in which the withholding or withdrawal of life-sustaining treatment is carried out following a patient’s request. I claim that the very arguments Koh presents against the legalization of physician-assisted suicide may be arguments against the extension. In particular, the extension presupposes a new social consensus just as the current performance period for withholding or withdrawing life-sustaining treatment was based on the social consensus that existed at the time that legislation was passed. Additionally, I argue that certain safeguards must be established or implemented to respect the right to self-determination in our society. For example, the monitoring and service of end-of-life care must be enhanced in order to prevent any coercion or abuse in individual decisions on life-sustaining treatment.

Published: July 2023

Quality is a service provided to users based on specifications or standards that have been set. A quality mosque is one of the driving factors for the community to attend prayer and pray in congregation at the mosque. Despite this, one of the factors associated with the lack of individual attendance at mosques is the level of mosque quality that is less than satisfactory. Therefore, this study was conducted with the aim of evaluating the level of mosque quality based on the perception of mosque congregations and the effect of a quality mosque on the implementation of congregational prayers in mosques in the state of Kelantan. A total of 618 data were obtained from mosque congregations in Kelantan which were analyzed using SmartPLS 3.0 software. The findings of the study prove that a) the community's perception of the quality of the mosque is high (M=6.18-6.22; SD:0.93-0.96) and b) there is a positive and large influence of the quality of the mosque on the performance of congregational prayers in the mosque (ß=.775 , t=29.578, p<0.01, f2=1.508). Based on the results of IPMA's analysis in PLS, quality mosque management is the most important factor that affects the execution of congregational prayers in mosques followed by the quality of religious lectures in mosques, the quality of mosque infrastructure and facilities as well as the quality of cleanliness, cheerfulness and safety of mosques. This finding proves that all elements of the quality of this mosque affect the presence of congregations to perform congregational prayers in mosques in the state of Kelantan.

Published: July 2023

Photoacoustic microscopy (PAM) has gained increasing popularity in biomedical imaging, providing new opportunities for tissue monitoring and characterization. Resolution enhancement and denoising are two critical tasks for PAM image reconstruction and post-processing. With the development of deep learning techniques, Convolutional Neural Networks (CNN) have been used for PAM. However, there exist several inherent challenges for this approach. The available PAM datasets used for training are limited and pre-trained models with conventional pixel level constraints are error prone. This work presents a Unified PhotoAcoustic Microscopy image reconstruction Network (UPAMNet) for both image super-resolution and denoising. The proposed method takes advantage of deep image priors by incorporating three effective attention based modules and a mixed training constraint at both pixel and perception levels. With the proposed framework, transfer learning is used to mitigate the domain gaps between different datasets. The generalization ability of the model is evaluated in details and experimental results on different PAM datasets demonstrate the superior performance of the method compared to the current state-of-the-art.
Waveform-Domain Adaptive Matched Filtering: A Novel Approach to Suppressing Interrupted-Sampling Repeater Jamming
Authors: Su Hanning , Bao Qinglong , Pan Jiameng , Guo Fucheng , Hu Weidong
Published: July 2023

The inadequate adaptability to flexible interference scenarios remains an unresolved challenge in the majority of techniques utilized for mitigating interrupted-sampling repeater jamming (ISRJ). Matched filtering system based methods is desirable to incorporate anti-ISRJ measures based on prior ISRJ modeling, either preceding or succeeding the matched filtering. Due to the partial matching nature of ISRJ, its characteristics are revealed during the process of matched filtering. Therefore, this paper introduces an extended domain called the waveform domain within the matched filtering process. On this domain, a novel matched filtering model, known as the waveform-domain adaptive matched filtering (WD-AMF), is established to tackle the problem of ISRJ suppression without relying on a pre-existing ISRJ model. The output of the WD-AMF encompasses an adaptive filtering term and a compensation term. The adaptive filtering term encompasses the adaptive integration outcomes in the waveform domain, which are determined by an adaptive weighted function. This function, akin to a collection of bandpass filters, decomposes the integrated function into multiple components, some of which contain interference while others do not. The compensation term adheres to an integrated guideline for discerning the presence of signal components or noise within the integrated function. The integration results are then concatenated to reconstruct a compensated matched filter signal output. Simulations are conducted to showcase the exceptional capability of the proposed method in suppressing ISRJ in diverse interference scenarios, even in the absence of a pre-existing ISRJ model.

Deleuze, Beckett y el teatro del agotamiento
Authors: Perrone Nicolás
Published: July 2023

El presente artículo aborda uno de los textos menos trabajados de Gilles Deleuze, L’Épuisé, donde el filósofo analiza cuatro piezas teatrales-televisivas de Samuel Beckett y despliega la problemática del agotamiento de la palabra en la obra del dramaturgo irlandés. Este agotamiento es pensado por Deleuze en relación con cuatro elementos: las cosas, la voz, el espacio y la imagen. Desde nuestro punto de vista, entendemos que este trabajo evidencia la última figura con que el filósofo piensa el teatro y su devenir ante la imagen audiovisual. Los elementos que se ven agotados en las piezas de Beckett son el índice, además, de un tipo de teatralidad que implosiona la representación dramática en favor de un devenir hacia la imagen.

Single lap joints are the most used bonded joints in engineering. Unfortunately, modeling correlations between apparent shear strength and failure modes is not an easy task. This paper tries to address relationships between apparent shear strength, failure modes, and micro-structural failures. To be able to establish a correlation between chemical changes and the failure morphology of an industrial epoxy-based adhesive nano-modified by carbon nanotubes, a series of single-lap joints were prepared and tested. For this adhesive, the ductile-like fracture is controlled by changes in the aromatic ring (C-O stretching at 1,176 cm-1, C-C stretching at 1,514 cm-1, and C = C stretching at 1,593 cm-1) and ethers group (C-O-C stretching at 1,247 cm-1). Changes in the ethers group, however, have less influence than the ones in aromatic rings. Variations in oxirane groups (C-O-C stretching at 836 cm-1, and rotations of CH2 at 695 and 756 cm-1) are more related to brittle-like microscopic failure. A small number of chemical bonds, specifically characterized by low chemical functional intensity, are associated with premature or brittle-like failure. However, concurrently, another mechanism that existed simultaneously was the ability of carbon nanotubes to alter the path of propagating cracks. This phenomenon was experimentally spotted. The macroscopic cohesive failure is controlled by the ductile-like failure at microscopic failure, while the adhesive failure is related to the brittle-like failure. Moreover, for the first time two different conditions, i.e., macroscopic quantities, apparent shear strength, failure modes, and microscopic quantities of brittle/ductile areas aspect ratios are combined in a mathematical model. This model can predict single-lap joint failure strength based on microscopic quantities.

Authors: Zhao Jian
Published: July 2023

Face detection is a biometric technology that automatically contains facial feature information. It integrates digital image processing, pattern recognition, and other technologies and collects images or video streams containing human faces by cameras or cameras for automatic detection and tracking. Starting from the idea of local features and deep learning, aiming at the problem that traditional convolutional neural network (CNN) only extracts features from the whole image and ignores practical local details, this article proposes a deep CNN model based on the fusion of global and local features. It explores the face detection algorithm with better performance under the interference of illumination, expression, and other internal or external factors. This method designs a suitable network structure according to the size of the training data set, and the core technology is the debugging of super parameters. The simulation results show that compared with SVM, the improved CNN has obvious advantages in the later stage of operation, and the error is reduced by 36.85%. Compared with the traditional face detection method, it can automatically extract image features and also automatically learn its model and get a higher recognition rate.

An automated fire alarm system is a vital safety facility for modern fire fighting. It is an essential guarantee for people to find fires early and take effective measures to control and extinguish them in time. This article proposes a multi-sensor data fusion algorithm based on artificial neural network (ANN) technology, which intelligently processes various environmental characteristic parameters detected by multi-sensors, effectively detects real fire signals, and realizes early fire monitoring and alarm. The simulation results show that compared with the fuzzy clustering algorithm (FCM), the MAE of the proposed data fusion algorithm is improved by about 15%, and the recall is improved by about 10%. It can not only overcome the instability and limitation of a single sensor, but also grasp the system information more comprehensively and accurately. The data fusion technology is applied to the fire monitoring system, and multiple sensorsmultiple sensors collect the data collect the data, and then processed by data fusion technology. By making full use of multidimensional information, the fire monitoring and identification can be better completed, the false alarm rate and the false alarm rate can be reduced, the system is more sensitive and reliable, and the performance of the fire alarm system can be improved.

Systemic lupus erythematosus (SLE) with oral desquamative lesions is one of the rare clinical entities. Periodontal disease and SLE display various mechanisms and possess a wide range of pathological characteristics. The tissue destruction mechanism of periodontitis and autoimmune diseases share similar pathways, and mounting reports studied the association between these two entities. The present case is of a 24-year-old female patient who complained of generalized widening of spaces in between the teeth. Along with it, She suffered from loss of hair, weakness, edema in the legs as well as arthralgia. The patient was identified to be suffering from SLE according to the American Rheumatism Association and European Academy of Dermatology and Venereology criteria 1 year before she reported to the dentist. She suffered from hair loss, weakness, arthralgia as well as edema in the legs. Based on the oral, clinical, and radiographic findings, she was diagnosed with aggressive periodontitis case. After nonsurgical periodontal treatment, the flap was reflected, debridement was done, after root conditioning with tetracycline, bovine osseous xenograft was placed in all the sites where ever there is angular bone loss, later sutured with interrupted direct loop suturing technique with 4-0 silk suture. Clinical and radiographic evaluation was done every 6 weeks to check the progress of the treatment. 6 months and 8-year follow-up revealed satisfactory clinical and radiographic outcomes. Based on the present case report and the previous literature, we recommend the use of xenograft in treating aggressive periodontitis patients.

Authors: Okonkwo Ogugua Ndubuisi , Hassan Adekunle Olubola , Agweye Chineze Thelma , Victor Umeh , Akanbi Toyin
Published: July 2023

Background:

Optical coherence tomography (OCT) is a noninvasive, frequently used imaging technology that enables detailed viewing of retina anatomy. It is used to monitor disease progression in retinitis pigmentosa (RP) eyes, including detecting changes in retinal thickness.

Purpose:

The purpose of the study is to determine the clinical presentation and macular morphology in RP eyes using OCT imaging.

Methods:

A retrospective review of case records and OCT scans in eyes diagnosed with RP in two ophthalmic clinics in Nigeria. Biodata, Snellen best-corrected visual acuity (BCVA), intraocular pressure (IOP), vertical cup-to-disc ratio (VCDR), and presence of maculopathy were determined. Data were analyzed using IBM SPSS version 22.0 (IBM Corp. Armonk, NY, USA).

Results:

Fifty-five eyes of 28 patients (18 males and 10 females), with a mean age of 47.16 ± 15.56 years (22–77 years), were studied. 40–49 years was the most frequent age group, 28.6%. Severe visual impairment occurred in 22% of eyes and myopia in 32%. Twenty-nine percent had undergone cataract surgery or had a significant cataract. The mean IOP was 11 mmHg, and the mean VCDR was 0.46. On OCT examination, macular atrophy was the most common finding in 74.5% of eyes, epiretinal membrane in 16.3%, cystoid macular edema in 7.3%, vitreomacular adhesion in 5.4%, and vitreomacular traction in 1.8%. There was no association between macular morphology, macular thickness, and BCVA (P = 0.155, P = 0.424).

Conclusion:

OCT provides information on macula structure in RP eyes. About 14.5% of eyes had a normal macula, while 85.5% had a maculopathy, confirming that RP eyes have a higher rate of maculopathy than non RP eyes. OCT evaluation of an RP eye should be a standard workup for the early detection of such maculopathy and monitoring for disease progression.

Authors: Sharma Pulak , Baghel Anurag
Published: July 2023

Introduction:

Chronic osteomyelitis (Chr OM) may result as a sequel of acute hematogenous infection or following open fractures or orthopedic surgeries. Among various osteoarticular infections, Chr OM is one of the most challenging in terms of treatment. In the present study, we evaluate the outcome of antibiotic cement-coated nails in the treatment of chronic pyogenic osteomyelitis and also discuss the future innovations in field of antibiotic-compatible biomaterials for coating the implants.

Materials and Methods:

Twelve cases of Chr OM (5 hematogenous and 7 exogenous following trauma or surgery) were operated by intramedullary nail coated with antibiotic-impregnated bone cement from September 2018 to January 2021. All the cases had bacteriological confirmation of infection by deep curettage and its subsequent culture sensitivity. K nail was used in 10 cases and elastic stable intramedullary nails were used in 2 cases.

Results:

Out of 12 cases, 8 were male and 4 were female. The average duration of follow-up was 13 months. Infection was controlled in all the cases (two cases required repeat antibiotic-coated nailing), and there was no incidence of relapse in any case. The control of infection was assessed by clinical assessment and laboratory parameters.

Conclusion:

Antibiotic cement-coated nails are an effective method in local control of infection in Chr OM without any systemic side effect.
Subjective Assessments of Voice in Parkinson’s Disease Subjects with and Without STN-DBS Therapy
Authors: Onder Halil , Bahtiyarca Zeynep Tuba , Comoglu Selcuk
Published: July 2023

Introduction:

The causal relation between STN-DBS and speech problems and the associated clinical features are in the incipient stages of being investigated.

Methods:

All the Parkinson's disease (PD) subjects with and without STN-DBS who applied to our movement disorders outpatient clinics between January 2022 and June 2022 and agreed to participate in the study were enrolled. The demographic data and clinical features were noted. Besides, the MDS-UPDRS was administered during the medication off-state in all subjects. All the participants completed the voice handicap index (VHI). Besides, the Freezing of Gait Questionnaire (FOGQ) and the quality of life (QoL) scales including the Parkinson's Disease Questionnaire (PDQ-39) and the Schwab and England Activities of Daily Living (ADL) scale were also administered to all the individuals.

Results:

We have included 66 patients with PD (F/M = 23/43). Thirty-five patients were those with DBS therapy whereas 31 patients were without. The results of the comparative analyses between the patients with and without DBS therapy revealed that the DBS group had a higher disease duration (P = 0.006) and FOGQ scores (P = 0.008). The VHI scores did not differ between groups (P = 0.577), and the correlation analyses did not reveal an association between the VHI scores and the duration of DBS therapy. However, the VHI scores correlated with the disease duration as well as the FOG scores.

Conclusion:

We did not find convincing evidence supporting the increased risk of speech disturbance with STN-DBS therapy. We suggest that the frequent existence of speech disturbance in this patient subgroup with STN-DBS is associated with the classical nature of PD.

Authors: Salim Hanan M. , Abdelmonem Mervat M. , ElSayed Ahlam M.
Published: July 2023

Background

The most common sexual dysfunction problem for women with cervical cancer is decreased sexual desire.

Aim

The aim of the present study was to evaluate the effect of nursing counseling guided by BETTER model on sexuality, marital satisfaction, and quality of life among cervical cancer women.

Design

A quasi-experimental design was used.

Patients and methods

A purposive sample of 44 women with cervical cancer who attended the oncology outpatient clinic at Zagazig University Hospital and Elmabera Hospital in the Sharkia Governorate was recruited.

Tools

A structured interviewing questionnaire, Female Sexual Function Index (FSFI), and a short version of the Quality of Life Enjoyment and Satisfaction Questionnaire were used to gather data.

Results

The mean score of all female sexual function index domains was improved significantly (P<0.001) after intervention as compared with before intervention. Moreover, following applying nursing counseling guided by the BETTER model compared with before intervention, there was a highly significant improvement (P=0.0001) in the quality of life enjoyment and satisfaction among study participants. Following the adoption of the nursing instructions, there was a positive association between the overall Female Sexual Function Index score and quality of life.

Conclusion

The quality of life and sexual function of women with cervical cancer have improved.

Recommendation

Implement a BETTER sexual counseling model to handle sexual dysfunction in oncology units. The availability of facilities and decision-making aids for individuals in need, as well as the promotion of women counseling activities about cervical cancer and sexuality, are all necessary.

Client-Centric Prosthetics and Orthotics Practice Model in Technology Management
Authors: Kumar Deepak , Ranjan Priya , Kumar Pramanjan
Published: July 2023

Innovation in technology has changed the way we interact, collaborate and conduct business. In the next 10 years, there will be a lot of changes in how we, as patients, clients and healthcare workers, experience healthcare. As they consider how to adapt medical and clinical specialists who focus on devices, such as prosthetists and orthotists, are presented with both an opportunity and a challenge. Less focus is placed on engineering and business abilities in the current prosthetic and orthotic education and practice, and more emphasis is placed on clinical skills. However, each of the three is important for a prosthetics and orthotics business to be successful and last for a long time. Furthermore, the latter two will have a significant impact on how prosthetics and orthotics look in the future. It is unclear how contemporary prosthetic and orthotic professionals can respond most effectively. In this editorial, one option is to rebalance their professional character so that the three most important parts are given equal weight. As a result, a Clinical Prosthetic Orthotic Technology Management Professional would practice their profession in a way that is client-centred, functionally grounded and incorporates eight professional traits: professional, advocate, scholar, leader, communicator, collaborator, assistive technology expert and business justification specialist.
