Published: July 2022

Incidence of diabetes are common among population around the world. Diabetes may lead to other complication and increasing morbidity and mortality. Many ways have been done to treat and prevent the development of diabetes. In addition of conventional pharmacotherapy, therapeutic therapy shown good opportunity to maintain and improve diabetic conditions. Vitamin D3 is known as nutraceutical and has good opportunity to develop the medication of type 2 diabetes. In another way, vitamin D3 naturally easy to damage by environmental condition. To overcome this weakness, researcher around the world have developed the method for protecting unstable compound as vitamin D3 with encapsulation. Liprotide is one of the various materials which can be used for encapsulation. Combination of lipid and protein molecules is expected to be a carrier and protector of vitamin D3 in gastrointestinal system. Here we review the research advances of liprotide as nanocarriers and vitamin D3 as nutraceuticals to discuss in applied on type 2 diabetes.

Published: July 2022

A new species of dobsonfly from Venezuela,Corydalus ralphiMartins, Azevêdo, Hamada & Contreras,sp. nov., was discovered a decade after the last description of a species of this genus in the country. The new species is morphologically similar toC. wanningeriContreras-Ramos & von der Dunk, sharing a uniform reddish coloration of body and wings and similar male genitalic structures. Likewise, it shares this particular coloration withC. neblinensisContreras-Ramos but the genitalic structure fits within theC. crossiContreras-Ramos species group. Two specimens, one male and one female, were collected on Tarotá River, in the Gran Sabana region, Canaima National Park, in southern Venezuela. A key to identify males of the Venezuelan species ofCorydalusis provided.
New species of the genus Chimarra Stephens from Africa (Trichoptera, Philopotamidae) and characterization of the African groups and subgroups of the genus
Authors: Blahnik Roger , Andersen Trond
Published: July 2022

This paper is primarily based on collections in Tanzania and Ghana in 1990–1991 and 1991–1994, respectively. In all, 46 species ofChimarrawere collected, 31 of them new species. All these species are illustrated or re-illustrated and described in the paper. Additionally, five species from Africa from collections in Illinois and Minnesota, four of them new, are included. This provided the incentive to review the species ofChimarrafrom the African subregion and assign the majority of them to species groups and subgroups. In the process, several species were synonymized. In all 147 valid species are recognized, of which 51 are treated in this paper. Two major species groups are recognized for Africa, themarginataGroup and thegeorgensisGroup. The former is based on the type species for the genus; this is the first formal characterization of this group, as distinct from other species groups in the subgenus. Mainland African species in themarginataGroup mostly fall into four large species-diverse subgroups, but a number of smaller subgroups are also recognized. Membership in these subgroups is specified for the majority of African species and characters defining the subgroups informally discussed. ThegeorgensisGroup includes a single Asian species and nine previously described African species. They are assigned to two subgroups, one newly recognized in this paper. Several additional species were considered unassigned to subgroup within thegeorgensisGroup. The majority of the new species described in this paper belong to thegeorgensisGroup.
Entrepreneurs et pouvoir politique à l’heure du Hirak en Algérie : des intérêts irréconciliables
Authors: El Mestari Faouzi
Published: July 2022

Cet article a pour objectif d’analyser le type de rapport prévalant entre le pouvoir politique algérien et les capitalistes nationaux avant et pendant le Hirak et, plus précisément, le degré de participation de ces derniers à la décision politique. L’hypothèse défendue ici est que l’incorporation de l’oligarchie entrepreneuriale dans la coalition dominante, loin de s’apparenter à une promotion politique de la bourgeoisie algérienne, a accru les tendances historiques à la division sociopolitique entre les factions dirigeantes et la majorité des grands chefs d’entreprise.

Pratiques néopatrimoniales et stratégies de classement des élites libyennes en temps de conflit
Authors: Rahem Soraya
Published: July 2022

Cet article porte sur l’analyse de « moments critiques » ( critical junctures ) dans la transition politique libyenne, afin de mettre en évidence les processus de reconfigurations élitaires, tant dans leurs statuts que dans leurs stratégies ou leurs pratiques. Ces moments structurent l’accélération des mécanismes de compétition entre acteurs et illustrent particulièrement la recomposition d’anciennes pratiques d’État rentier en nouvelles logiques néopatrimoniales. Prenant place dans un contexte spécifique et discontinu qui est celui de la guerre civile, tout en étant, aussi, marqués par les stigmates du passé, ces processus permettent ainsi de questionner la réalité d’une transition politique libyenne.

Physical exercise in menopause: a review of physiological changes
Authors: Ribeiro I.C. , de Lucena E.G.P. , Oliveira A.S. , Fernandes P.T.
Published: July 2022

Menopause is characterised by several hormonal changes through which women undergo aging. These changes lead to psychological, somatic, urogenital and vasomotor symptoms that influence the quality of life of women. Studies have shown that physical exercise can benefit women in the pre- and postmenopausal stages. However, the physiological benefits of exercise during the menopausal period have been less explored, as well as which type of exercise is most recommended at this stage of life. Therefore, the present review aimed to investigate the physiological changes promoted by the practice of physical exercise during the menopause period. A search for scientific articles was performed in the PubMed database using the descriptors ‘menopause’ and ‘exercise’ and the ‘AND’ connector. The period selected for this study was from 2014 to 2018. After applying the inclusion and exclusion criteria, five articles were selected. As a result, studies suggest that physical exercise promotes hormones, body composition and positive cardiovascular changes, decreases menopausal symptoms and improves psychosocial health. In addition, it is associated with an improvement in the quality of life.
Comparison of Bilateral Reading Performance Among Two Presbyopia-Correcting Intraocular Lenses
Authors: Benyoussef Anas-Alexis , Reboux Noémi , Cochener Béatrice
Published: July 2022

PURPOSE:

To evaluate and compare the performance of a trifocal diffractive intraocular lens (IOL) and a lens combining a bifocal diffractive profile and extended depth of focus (EDOF) profile.

METHODS:

This non-randomized, prospective comparative study included 42 patients (84 eyes) undergoing lens surgery with implantation of either the FineVision HP trifocal IOL (PhysIOL) or TECNIS Synergy bifocal EDOF IOL (Johnson and Johnson Surgical Vision). There were 21 patients (42 eyes) in each group. The primary outcome was reading speed at high contrast and luminance. Secondary outcomes were reading speed at lower contrasts and luminances, visual acuity at all distances (distance, intermediate, and near) with and without correction, and quality of vision.

RESULTS:

The reading speed at high contrast (100%) and high luminance (100%) was better in the Synergy group (
P
= .01). This difference between the two IOLs seemed to be preserved at lower contrasts and luminances. There was no statistically significant difference between visual acuities except for monocular uncorrected intermediate visual acuity (
P
= .046) in favor of the FineVision HP IOL. The mean spherical equivalents in the FineVision HP and Synergy groups were 0.14 ± 0.64 and 0.10 ± 0.33 diopters without significant difference between these means (
P
= .78). The defocus curve was more dome-shaped for the Synergy IOL. The evaluation of visual symptoms was comparable in both groups. The glare halo (Halometry test; Aston University) was smaller in the FineVision HP group (
P
= .03).

CONCLUSIONS:

The Synergy IOL appears to provide better reading speed and is less sensitive to refractive error. Both lenses provided excellent distance, intermediate, and near vision.

Accuracy of Formulas for Intraocular Lens Power Calculation After Myopic Refractive Surgery
Authors: Lanza Michele , Ruggiero Adriano , Ha Jason , Simonelli Francesca , Kane Jack X.
Published: July 2022

PURPOSE:

To assess the accuracy of the following intraocular lens (IOL) power formulas: Barrett True-K No History (BTKNH), Emmetropia Verifying Optical 2.0 Post Myopic LASIK/PRK (EVO 2.0), Haigis-L, American Society of Cataract and Refractive Surgery (ASCRS) average, and Shammas, designed for patients who have undergone previous myopic refractive surgery, independent of preexisting clinical history and corneal tomographic measurements.

METHODS:

Data from 302 eyes of 302 patients who previously underwent myopic refractive surgery and had cataract surgery done by a single surgeon with only one IOL type inserted were included. The predicted refraction was calculated for each of the formulas and compared with the actual refractive outcome to give the prediction error. Subgroup analysis based on the axial length and mean keratometry was performed.

RESULTS:

On the basis of mean absolute prediction error (MAE), the formulas were ranked as follows: Haigis-L (0.61 diopters [D]), ASCRS average (0.63 D), BTKNH (0.67 D), EVO 2.0 (0.68 D), and Shammas (0.69 D). The Haigis-L had a statistically significant lower MAE compared with all formulas (
P
< .05) except the ASCRS average. Hyperopic mean prediction errors were seen in all formulas for axial lengths of greater than 30 mm or mean keratometry values of 35.00 diopters or less.

CONCLUSIONS:

The Haigis-L and the ASCRS average formulas provided the most accurate results in the overall population evaluated in this study. Moreover, according to data observed, it is important to be careful handling very long eyes and very flat corneas because hyperopic refractions could be more common.

The comparative study of resolving parameters for a family of ladder networks
Authors: Zayed Mohra , Ahmad Ali , Nadeem Muhammad Faisal , Azeem Muhammad
Published: July 2022

For a simple connected graph $ G = (V, E) $, a vertex $ x\in V $ distinguishes two elements (vertices or edges) $ x_1\in V, y_1 \in E $ if $ d(x, x_1)\neq d(x, y_1). $ A subset $ Q_m\subset V $ is a mixed metric generator for $ G, $ if every two distinct elements (vertices or edges) of $ G $ are distinguished by some vertex of $ Q_m. $ The minimum cardinality of a mixed metric generator for $ G $ is called the mixed metric dimension and denoted by $ dim_m(G). $ In this paper, we investigate the mixed metric dimension for different families of ladder networks. Among these families, we consider Möbius ladder, hexagonal Möbius ladder, triangular Möbius ladder network and conclude that all these families have constant-metric, edge metric and mixed metric dimension.
AR-Supported Mind Palace for L2 Vocabulary Recall
Authors: Larchen Costuchen Alexia , Font Fernández José María , Stavroukalis Minos
Published: July 2022

MnemoRoom4U is an AR (Augmented Reality) tool that uses a memory-palace strategy for foreign-language training. A memory palace helps information recall with the aid of object association in visualizations of familiar spatial surroundings. In MnemoRoom4U, paper or digital flashcards are re-placed with virtual notes containing L1 words and their L2 translations that are placed on top of real physical objects inside a familiar environment, such as one’s room, home, office space, etc. The AR-supported notes aid associative memory by establishing a relationship between the physical objects in the user’s mind and the virtual lexis to be retained in L2. Learners first set up a path through their familiar environment, attaching virtual sticky notes—each containing a target word to be memorized together with its corresponding source-language translation—to real-life objects (e.g. furniture in their homes or offices). They then take the same path again, reviewing all the words, and finally carry out a retention test. MnemoRoom4U is a technological artifact designed for specific didactic purposes in the Unity game engine with the ARCore augmented-reality plug-in for Android. This work takes a Design-Science approach with phenomenological, exploratory underpinnings tracking back to the efficiency of spatial mnemonics previously reported quantitatively and combines it with AR technology to effect L2 vocabulary recall.

Published: July 2022

Until now, the higher education system in the Democratic Republic of Congo has relied on the traditional face-to-face teaching method, which consists in the real physical presence of students and teachers during classes and lectures. Thus, the United Nations Educational, Scientific and Cultural Organization (UNESCO) is currently advocating e-learning as the only alternative for education in the COVID-19 era. It goes without saying that this requires specific frameworks and appropriate resources, including access to a good quality internet connection. Several countries around the world have implemented this recommendation since the first quarter of 2020 to protect their populations from the significant risks of Covid-19 contamination. In educational environment however, given the disadvantageous realities of the Democratic Republic of Congo, including the cost and quality of internet, the low rate of electrification, and the lack of experience of the educational stakeholders involved, the migration to e- learning remains a challenge.  Thus, we propose in this paper a blended learning model that can smoothly introduce e-learning through a platform specially designed to integrate with the traditional way of delivering courses in Congolese higher education by combining the old method and e-learning based on ICT.

Published: July 2022

Tracking the evolution of learners' learning in a MOOC supports the e-learning operation and allows teachers to easily manage the massive number of learners enrolled in a distance learning course. In this work we started with a study where we were interested in identifying the common parameters that allow us to have a vision on the evolution of learners through the use of SPSS statistical software. This operation allowed us to determine the level of the learners, classify them and group them into homogeneous groups that facilitated their orientation towards courses that meet the characteristics of their profiles. On the basis of our case study, we were able to develop a computer system approach based on K-means learning software and data pre-processing means, for data mining with the aim of analyzing and revealing the parameters that have a great positive impact on the learners' learning, the system uses the identified parameters to classify and group the learners according to their profiles. This type of system is characterized by its autonomy and the ability to process a large amount of data. On the basis of the data used in our case study, we carried out experimental tests on the proposed system which showed its performance in solving our problem.

Authors: Moralista Rome , Oducado Ryan Michael , Robles Baby Rose , Rosano Daisy
Published: July 2022

Videoconference applications gained popularity when online learning became the new way of delivering instruction at all levels of education including graduate programs. However, excessive videoconferencing led to reports of fatigue among its users. Identifying the factors contributing to the videoconference exhaustion experience of graduate students is necessary. This study examined Zoom fatigue and selected associated factors among graduate students. An electronic one-shot survey using the Zoom Exhaustion and Fatigue scale was conducted among 109 graduate students of the College of Teacher Education in the Philippines. Correlation and predictive analysis were performed. Results of the study demonstrated a moderate level of Zoom fatigue with the highest level of fatigue in the general fatigue dimension. Pearson’s correlation analysis revealed a significant inverse correlation between attitude toward videoconferencing and Zoom fatigue. Non-verbal mechanisms of mirror anxiety, feeling physically trapped, hyper gaze, and cognitive load in producing non-verbal cues were significantly positively related to Zoom fatigue. Regression analysis revealed that the sense of being physically trapped and cognitive load in producing non-verbal cues remained significant predictors of Zoom fatigue. While videoconferencing supported educational activities and made schooling possible during the global disease outbreak, it is recommended to be mindful of the non-verbal factors contributing to Zoom fatigue.

Authors: Wan Juan
Published: July 2022

In this study, an undergraduate course in Wuhan City, China was chosen as the respondent and a questionnaire of influences of online learning support services on continued intention to use MOOC was designed. The influencing degree of four aspects of online learning support services (education teaching, curriculum resources, learning facilities and management services) on continued intention to use MOOC were analyzed. Moreover, differences in continued intention to use under various online learning contact time were discussed. Results demonstrated that the overall Cronbach α of the questionnaire was 0.872, KMO value was 0.833 (>0.8) and the corresponding P value was 0.000, indicating that the designed questionnaire had good reliability and validity. Education teaching, curriculum resources and learning facilities all have significantly positive promotions on the continued intention to use MOOC. According to the Kruskal-Wallis test statistics, online learning contact time presents typical “inverted V-shaped” relations with the learners’ continuous intention to use. Research conclusions have important values to maintain a relatively high learning intention of learners by strengthening learning support services and promote learning outcomes of MOOC and adopt specific learning support service strategies.

Authors: Yang Peifan , Liu Xia
Published: July 2022

With the college students having increasing needs for learning diversified knowledge and skills, online learning platforms for essential qualities enhancement have emerged one by one. However, due to lack of feedbacks from students, the comprehensive service quality of these platforms varies greatly. Therefore, it has certain practical significance to study how to evaluate the comprehensive services of online learning platforms. The current evaluation models are not suitable for online learning platforms, nor have they fully considered the dynamic and subjective feedbacks of students about their experience. To this end, this paper takes an online music education platform as an example and studies the evaluation on the comprehensive services of the online learning platform. First, the overall architecture design of an online learning platform for essential qualities enhancement was displayed, and the teacher-student interaction mode for the comprehensive services of the online learning platform was identified and analyzed. Then, the derivation process of the evaluation model was presented, the evaluation indicator system for the comprehensive service quality of the online learning platform constructed, and the comprehensive service evaluation model for the online learning platform consisting of the hierarchical model and the rough set-neural network evaluation model established. The experimental results verified the effectiveness of the constructed indicator system and evaluation model.

Published: July 2022

The striving to obtain more detailed information about the environment and control various processes leads to an increase in the number of connected sensor devices in various industrial areas. The collected large amount of data can be analysed in real-time. The sensors that build up the WSN have limited hardware resources and cannot process large amounts of data. The integration between WSN and cloud structures is an excellent method for storing, processing, accessing data via the Internet and solves the issue of the limited capacity of WSN. The big challenge to designing the WSN - cloud systems is establishing a communication channel (through different protocols) between devices in the network and cloud platforms. This project executes/perform a real experiment on the XBee sensor network and the ThingSpeak cloud, and the data transmission between them is forwarded using different protocols (HTTP, HTTPS, MQTT and MQTT-SN). The influence of the parameters of the transmitted packet on the delay, the CPU, RAM load has been studied. The results give some advantages of MQTT over other protocols in terms of data rate, CPU and RAM load when working with XBee sensor modules and integration between WSN and cloud structures.

Development of Mechanized System for Production of Date-Palm Jaggery Granules
Authors: Jagannadha Rao P.V.K. , Das S.K. , Das Madhusweta
Published: July 2022

Making of date-palm jaggery (popularly known as khejur gur) with its characteristic aroma and flavor is very popular all over India for making various sweet dishes and confectionery products. It is available only for a short duration between middle of November and end of January. The production of solid jaggery includes sap collection (juice) by tapping, filtration, concentration by boiling, cooling of concentrated juice followed by moulding, drying, and storage. Making date-palm jaggery from the raw juice is an art and requires some skill to get the characteristic aroma bearing product with optimum stickiness and colour. Solid jaggery deteriorates rapidly and becomes liquid within 1 or 2 weeks due to its moisture content, invert sugar, and hygroscopic nature. Granular jaggery having low moisture content (1 - 2%d.b) is very popular, tenders several advantages, such as extended shelf-life, easy handling and distribution, high demand for domestic and international markets. It could be made from either solid jaggery or concentrated juice. Therefore, a manually-powered operated granulator (20 kg capacity) was designed, developed, and tested with 5 levels of moisture content (8.4 to 16.25 %db) and 5 levels of rotational speed (48 - 132 rpm) of blades for the production of desired size of jaggery granules. The mass mean diameter of the particles varied linearly with the moisture content of the feed, yielding particles having an average size of 656 µm (Dp) for feed containing 8.4 (%db) moisture. The mean particle size was as low as 700 µm when the machine was operated at 132 rpm with feed moisture content of 12 (%db). The average particle size of 1000 µm is obtained at feed moisture content of 9.0 (%db) and the agitator rotational speed of 76 rpm.

The Bobbin Lace between Tradition and Innovation
Authors: Vale Cleonisia Alves Rodrigues do , Broega Ana Cristina , Montagna Gianni
Published: July 2022

Between Brazil and Portugal, bobbin lace is a practice that constitutes a cultural value without borders. But there is a serious risk of discontinuity of this tradition, due to the low demand for these lace associated with the decrease in the number of lacemakers, the lack of adaptation of contemporary computerized techniques, and to lack of interest of the younger generations. In the process of creating and making bobbin lace, it is possible to identify a particular problem that design can collaborate with. As a crucial component, the importance of the “piques” design for the process of making original laces is highlighted. There are few lacemakers who are specialized in the task of creating new “pique”. This research proposes the creation of a software that facilitates the recording of memory and the creation of new designs for bobbin lace. A bibliographical research was carried out in order to analyze possible existing similar solutions. For the proposition of the new software based on the resolution of a real problem and on the user's needs, it was decided to approach the interaction design methodologies

The physicochemical properties of the alloy obtained by reductive melting with the use of waste from the production of high-alloy steels and alloys have been studied. This is necessary to determine the technological aspects that reduce the loss of alloying components during the production and use of the alloying alloy. The research results indicate that the alloy treasure is represented by iron phases with the content of alloying elements as substitution atoms. The proportion of residual carbon, which was part of the carbide component and the residual unproduced reducing agent, provided the necessary reducibility during the use of the alloy. The microstructure of the alloying alloy was characterized by the presence of phase formations that differed in shape, size and chemical composition. The content of Ni in the studied areas of different phases varied in the range of 1.28–32.62 % wt., Cr-0.33–46.22 % wt., W-0.00–20.43 % wt., Mo – 0 .00–10.78 % wt. Mo, W, Nb were more concentrated in individual particles, which probably had a carbide nature. The research identified new technological aspects of processing high-alloy man-made waste to obtain the resource-saving alloying alloy with the possibility of replacing part of the standard ferroalloys in steelmaking. Indicators of the obtained alloy allow to smelt grades of alloy steels when replacing part of standard ferroalloys. Production and use of alloying alloy eliminates the need for storage of fine oxide metallurgical waste on the territory of enterprises. This allows to improve the sanitary conditions of workers to increase the level of safety of residents of the surrounding areas without additional costs for the maintenance of waste storage sites.

Some fashion brands and designers have been developing services and products in the last decade taking similarly, into consideration consumers that have some disability. Knowing that visual communication of a brand itself is not possible with unsighted consumers, it is necessary and relevant to investigate how consumers can create an emotional attachment with fashion brands. This paper aims to analyze the inclusive design approach and methods. Attending to the following question of investigation, “how visually impaired consumers are able to create an emotional relationship with fashion brands” the methodology for this paper is based on a mixed methodology. The literature review is based on scientific papers, informative articles, books, and report analysis. Regardless of the product or services, clothing brands established in Portugal usually do not have an inclusive approach. A set of hypotheses were formulated from the literature review analysis, which will be further tested using the data collected. It was not possible to set up the empirical study winch will be carried out in the future. This study will be of added value to guide future investigations and endorse the possible future success of fashion brands and designers in Portugal in the field of accessibility and inclusive design.

Clay from the Khmelnytskyi region was enriched in montmorillonite by separation of a fraction with a particle size  0.5 ∙ 10-6 m. The X-ray diffraction and thermal analyses suggest that the enriched clay composition is close to mono-mineral, that is, represented by ferric-type montmorillonite in the form of Ca and Mg. The mineral interlayer spacings are partially filled with natural organic matter. An exchange capacity of montmorillonite is 0.78 mmol/g as shown by the photocolorimetry studies of the adsorption of the cationic methylene blue (MB) dye. It is recommended that studied clay be used as an effective natural adsorbent for wastewater treatment and for the arrangement of geochemical barriers to prevent harmful substances from entering the environment.
Experimental Investigations of Removal of Phosphorus Compounds from Wastewater under Biological Purification
Authors: Tsytlishvili Kateryna
Published: July 2022

Today, most surface waters of Ukraine are eutrophied due to the entry into water bodies of a significant amount of nutrients – compounds of carbon, nitrogen and phosphorus. Nitrogen and phosphorus enter water bodies with wastewater, sewage from agricultural lands and livestock farms, as well as with precipitation, due to the decomposition of water biomass, aquatic vegetation and zoocenoses. In the presence of free carbon dioxide (the concentration of which depends on bicarbonate alkalinity and water pH) and at certain rates of biochemical oxygen utilization (BOD) 7.2 g of nitrogen and 1 g of phosphorus produce 115 g of algae, which decomposition then consumes 115 g of oxygen [1].

Drowning is a dramatic situation, with very serious consequences and with economic impact, since when it does not cause death, causes sequelae that will affect the victim throughout his life. With regard to children, the prevalence of drowning death is higher than deaths caused by tuberculosis or measles. Considering the context of these accidents, it is known that the immersion occurs without shouting or "noises", which makes it even more difficult to detect and rescue. Rescue agility is crucial for the survival of victims, as after being submerged for only 2 minutes, the victim loses consciousness and after 4 minutes brain damage can become permanent and unalterable. Even if they survive from being submerged for some time, the victims may suffer from severe and often irreversible neurological sequelae [1, 2]. From this perspective, developing safety mechanisms for children requires knowledge of the unique needs of these individuals, arising from the cognitive and motor development of this stage of human development [3, 4]. To foster this problem, the work proposes to develop a usual garment that contains an integrated rescue device for children. The main design challenge is the harmonious matching of the rescue device's function with the fashion item, making it unnoticed. The work presented is feasibility study (online survey), which aims to verify the acceptance of parents/guardians regarding the launch of such product concept, which is presently under development, and the requisites that it should comply with.

Natural zeolites are materials which, due to the peculiarities of their crystal structure and high adsorption and ion exchange properties, have wide prospects for use in technologies of adsorption purification of aquatic environments. The paper presents the results of laboratory research in dynamic and static conditions of sorption properties of natural zeolite, which is currently used for purification of natural water from suspended solids in industrial water treatment plants. The sorption capacity of different fractions of this zeolite to ammonium nitrogen, fluorides and petroleum products has been established.

Background:

There is a paucity of Indian studies assessing psychiatric morbidity among family members of subjects with alcohol use disorder.

Aim:

To study psychiatric morbidity in wives/life partners and children of alcohol-dependent patients.

Materials and Methods:

Fifty consecutive index patients diagnosed to be alcohol dependent according to the International Classification of Diseases-10 classification of mental and behavioral disorders diagnostic criterion for research reporting to psychiatry department were taken. The study was conducted on family members of alcohol-dependent patients who were enrolled in the study as subjects. These included both their children and spouses and they were evaluated for any psychopathology using M. I. N. I. AND M. I. N. I.-KID scales.

Results:

Out of 50 spouses and 67 children enrolled in the study group. Sixty-eight percent had psychiatric morbidity in spouses which include 34% had major depressive episodes. Spouses living in the nuclear family and illiterate had more psychiatric morbidity. Total psychiatric morbidity in children above 18 years was 56.25%, maximum being in alcohol and substance dependence. Total psychiatric morbidity in children between 6 years and 18 years was 31.37%, maximum being in generalized anxiety disorder (11.76%).

Conclusion:

Spouses of subjects with alcohol dependence have a high prevalence of psychiatric morbidity. Spouses living in the nuclear family had a more major depressive episode and generalized anxiety disorder. Psychiatric morbidity was more in illiterate spouses. Psychiatric morbidity was also high in children. Female children between 6 years and 18 years had more generalized anxiety disorder than males.
