Role of Resilience in the Social Competence and Psychological Well-being of Adolescents with Single Parents
Authors: Aneesh Athira , Sia Surendra Kumar
Published: February 2023

The current study investigated the role of resilience in the relationship between single-parent adolescents' social competence (SC) and psychological well-being (PWB). A total of 385 single-parent adolescents from Kerala (179 boys and 206 girls, Mean age=15.03, SD = 1.45) were selected using a convenient sampling method. 185 participants (48.1%) were from single-parent families due to the death of one parent, and the other 200 participants (51.9%) were from single-parent families due to divorce or separation. Data were collected using self-reported measures for social competence, resilience, and psychological well-being. Analysis of the data was performed using IBM SPSS and AMOS version 24. The results indicated that social competence and resilience are significantly correlated with the psychological well-being of single-parent adolescents. According to the findings, resilience completely mediates the linkage between SC and PWB. When compared to adolescents who experienced parental divorce or separation, those who lost one parent due to death reported higher levels of social competence, resilience, and psychological well-being. Except for antisocial behavior, one of the dimensions of social competence, adolescents from divorced or separated family backgrounds scored low on all other scales. No gender difference is identified in any of the variables in the present study. Adolescents living with grandparents and those who have siblings significantly differ from others. The findings have clinical as well as educational implications.
Role of Music Intervention on Professional Quality of Life and Work Stress: An Experimental Investigations
Authors: Gudi Harshika , Gowribhatla Yamini , Sharma Vidisha
Published: February 2023

Stress and burnout are quite synonymous with the fast-paced work environment of nurses. The purpose of this paper is to empirically investigate the effect of music therapy on perceived stress and professional quality of life (burnout, secondary traumatic stress, compassion satisfaction) among them. Data were collected through a structured questionnaire from a sample of 41 nurses working in a private multi-speciality hospital, in Hyderabad, India. The hypotheses were tested using paired sample t-tests. Perceived stress was measured using the Perceived Stress Scale (Sheldon Cohen). Burnout, Secondary stress, and Compassion Satisfaction were measured by the Professional Quality of Life scale - ProQOL5. Nurses in the experimental group were given live group music therapy in the form of group drumming improvisation for 30 mins followed by directed imagery and music for relaxation for a duration of 15 mins. The script of the imagery was chosen to be generic and safe for everyone to evoke positive and pleasant experiences. The music used for music and imagery was live raga improvisation in the Raga Brindavani Sarang. The findings showed that perceived stress, burnout, and secondary traumatic stress significantly decreased in the experimental group, confirming the positive effect of music therapy on an organizational sample such as nurses. The current research suggests how music and music therapy can be used as a tool for enhancing and maintaining well-being at the workplace. Implications of this study can be extended to see the effects of music therapy with an increased number of sessions and on other organizational samples like doctors, other medical staff, and technicians. Although the study's findings reveal the positive impact of music therapy with nurses, it cannot be generalized to all nurses in India, since the results and sampling area is limited to the hospital where the study was conducted in Hyderabad, India

Published: February 2023

Munkánk során egy szikes táj vegetációtípusainak osztályozását végeztük el, légi hiperspektrális adatok felhasználásával. A munka célja a hiperspektrális adatok alkalmazhatóságának vizsgálata volt e komplex társulásoknál, eltérő képosztályozási módszerek alkalmazásával. Vizsgálatunkban hagyományos osztályozó eljárások (Maximum Likelihood Classifier – MLC, Random Forest – RF és Support Vector Machine – SVM) eredményességét teszteltük 10 és 30 pixeles tanítóterületek felhasználásával. A mozaikolt hiperspektrális felvételen a zajszűrés és az információnyerés céljából MNF transzformációt alkalmaztunk. A légi hiperspektrális felvétel AISA EAGLE II szenzorral készült 1m terepi felbontásban. Társulástani besorolás és felszínborítás alapján összesen 20 vegetációosztályt alakítottunk ki. Az osztályokat további négy főbb élőhelykategóriába soroltuk: sztyeppék, nyílt szikes gyepek, szikes rétek, szikes és nem szikes mocsarak. Az SVM és az RF osztályozó eljárások, a pixelek számától függetlenül, majdnem minden vegetációosztálynál megbízhatóan működtek, nagy osztályozási pontosságot adtak. Az MLC bár nagy mintaszámnál nagy pontosságú osztályozást eredményezett, kis mintaszámnál számos osztály esetében alacsony megbízhatósággal működött. Az eredmények alapján elmondható, hogy a komplex fátlan táji környezetben a vegetáció osztályozásra az SVM megfelelő osztályozó lehet, mivel nagyobb pontosságot nyújt, mint az RF és az MLC. Az SVM bizonyult a legkevésbé érzékenynek a tanító területek mintáinak méretére, így alkalmas lehet azokban az esetekben, amikor néhány osztálynál az elérhető pixelek száma korlátozottan áll rendelkezésre.

Magyarország kistájait a D-e-Meter rendszer szántó minősítési eljárását használva minősítettük. A kitájak talajainak minősége és a talajféleségek kistájban betöltött területi arányai alapján számoltuk a kistájra jellemző földminőség mutatót. A kistájanként számszerűsített eredmények összehasonlítása révén értékeltük az ország szántóföldi növénytermesztési lehetőségeinek területi megoszlását. A kapott földminősítési eredmények alapján a kistájak termőföldjeinek minőségét bemutató és a kistájak földminőségi össz-potenciálját ábrázoló áttekintő térképeket szerkesztettünk. A kistájak között az Enyingi-hát jellemezhető a legmagasabb átlagos földminőség értékkel (108 D-e-Meter pont) míg a Vitányi-rögök kistája a legalacsonyabbal (20 pont). Az országos átlag 50,2 pont. A természetföldrajzi nagytájak közül a Kisalföld a legtermékenyebb, 68,9 pontos földminőségi átlagával. Ezt a Nagyalföld (63,4 pont), Dunántúli Dombság (60,9 pont) majd a jóval kevésbé termékeny Nyugat-magyarországi peremvidék (48 pont) Észak-magyarországi-középhegység (46,8 pont) és az általában legkedvezőtlenebb termőhelyi adottságú Dunántúli-középhegység (41,6 pont) követi. A nagytájakéhoz hasonlóan a kistájankénti átlagos értékek is jelentős minőségbeli változatosságot takarhatnak, ugyanakkor a kapott országos áttekintő térképek általánosságban a korábbiaknál megbízhatóbb képet atdnak a hazánk földminőségi mintázatáról.

Authors: Cseresnyés Imre , Tamás Júlia
Published: February 2023

The review deals with the stands of the alien Austrian pine (Pinus nigra Arn.) in Hungary, emphasizing the ecological consequences of the afforestation. A short historical overview about the establishment of pine cultures is presented with outlining the distribution of the stands among the major forestry regions of Hungary. The nature conservation and economic problems associated with Austrian pine are summarized, including: the local extinction of the species-rich native flora, the less valuable timber, the rapid physiological decay of trees followed by pathogen epidemics, the insufficient soil amelioration effect, as well as the special vulnerability to forest fires and non-native plant invaders. Applicability of the conifer for land reclamation purposes is also introduced. Finally, we describe some directives and proposals concerning the alteration of Austrian pine plantations to native woody associations complying with the sustainable forest management policy.
Changing in organic carbon dynamics and biological activities in clay loam brown forest soil by application of municipal sewage sludge
Authors: Bayoumi Hamuda Hosam E. A. F.
Published: February 2023

A greenhouse pot experiment was conducted to assess the effects of two municipal sewage sludges (MSS) application on change in the dynamics of organic carbon, microbial population, enzymatic activities and alfalfa growth in relation to heavy metal content and nutrient release from sewage sludge in clay loam brown forest soil. The treatment of MSS increases soil organic matter and improves soil structure. Municipal sewage sludge of high heavy metal content (HHM) significantly decreased soil bioproductivity, reduced its biochemical properties, and lowered the microbial contents in comparison with MSS of low heavy metal (LHM) content. Total alfalfa dry matter yield and nitrogen content increases linearly with increasing MSS application rates. Soil treated with MSS rates of 40 and 60 % exhibit higher in crop dry matter, microbial contents and enzymatic activities than the control. Overall, our results demonstrate that soil treated with LHM content can improve soil quality and soil biological and biochemical properties.

Published: February 2023

A Fejér megyei Sárrét területén vett 500 centiméteres bolygatatlan fúrásmintát 5-10 centiméterenként tártuk fel és az így kapott mintákból 41-et elemeztünk ki. Ezen minták segítségével 5 pollenzónát (LPAZ) különítettünk el, amelynek első két zónája a pleisztocén-holocén idején bekövetkező klímaváltozást tükrözi a területen. A pollenadatok alapján rekonstruáltuk az akkori vegetáció és klíma változását. Mivel nem állt módunkban, hogy radiokarbon kormeghatározást végezzünk, így az egyes zónák datálását korábbi palinológiai és malakológiai vizsgálatok alapján készült koradatok segítségével kíséreltük meg (SÜMEGI et al. 2007). A kutatás célja az ezen a területen az ezt megelőző kutatások kiegészítése, azok eredményeinek újabb adatsorokkal való alátámasztása. További célunk, hogy új fúrások segítségével részletesebb információkat nyerjünk a terület pleisztocén vegetációtörténetéről.
Lakossági üvegházgáz kibocsátások és semlegesítésének lehetőségei
Authors: Patocskai Mária , Győrfi Tamás
Published: February 2023

A környezeti problémák globálissá válása miatt egyre időszerűbbé válik a lakossági fogyasztásból származó környezetterhelés számszerűsítése. Ennek különböző módjai közül a lakosság fosszilis erőforrásokon alapuló életviteli tevékenységeiből származó ÜHG (üvegházhatású gáz) kibocsátás kiszámítását választottam. Ehhez három legnagyobb energiafogyasztással járó tevékenységünkhöz felhasznált energiamennyiséget vettem alapul: a villamosenergia-felhasználást, a közlekedést és a fűtést. Ezek alapján a hazai átlagot, valamint hét alföldi település egy főre eső átlagát számoltam ki. Ahhoz, hogy az eredményeket értelmezni lehessen, ezért a kapott ÜHG értékeket először összehasonlítottam a hazai ÜHG leltárral. További értelmezés miatt területalapúvá váltottam őket: összehasonlítottam a hazai erdők elnyelő kapacitásával. Vizsgáltam még, hogy a kiválasztott tevékenységek során felszabaduló ÜHG-ok hogyan aránylanak a felhasznált energiamennyiségekhez. Az eredmények rávilágítanak életvitelünk energiaigénylő tevékenységeiből származó környezetszennyezés mértékére: a lakosság környezeti problémákkal kapcsolatos személyes felelőssége, a fogyasztói felelősség egyáltalán nem elhanyagolható.
A Niche Discovery in the Metaverse

Published: February 2023

Over time, social media has evolved. In this study, secondary, targeting, and portfolio matrix models are integrated for competitive positioning. Similarly, to others, Facebook continues to serve a strategically diverse audience of targeted users. Due to the Covid-19 Pandemic, there was a need for social engagement, distancing, and isolation. The Facebook platform faced competition among social media platforms in trying to attract a younger demographic, Generation Y, Z, and A. Founder Mark Zuckerberg announced Meta to address this challenge. The Metaverse was launched into the universe thanks to Facebook's innovative genius. The evolutionary strategy addressed the preferences of younger generations of users. As the Metaverse mimics real-life imagery, it would alter the mundane socialization strategy used by older users. In the Metaverse, unlimited communication and socialization can be harnessed; however, tremendous opportunity exists through the integration of Opportunity Zones (OZ's). Developing OZ tracts will promote growth and development of residential and commercial properties. Through the Metaverse, tax incentives and ownership rights are communicated. With a large segment of younger users, Facebook's platform has reshaped both the urban and rural landscape in America.

Pemberdayaan Penyandang Disabilitas Fisik Melalui Pelatihan Vokasional pada Program Rehabilitasi Sosial
Authors: Pangestuti Dinah
Published: February 2023

Abstrak

Artikel ini mendeskripsikan tentang pemberdayaan penyandang disabilitas fisik melalui pelatihan vokasional. Masalah utama yang dihadapi adalah rendahnya kemampuan serta ketergantungan pada orang lain Terlebih lagi umumnya penyandang disabilitas fisik masih berada pada usia produktif, sehingga perlu diarahkan, dibina, diberdayakan dan diberi kesempatan untuk menumbuhkembangkan potensi yang dimiliki. Tujuan untuk mendeskripsikan proses pelaksanaan pemberdayaan penyandang disabilitas fisik melalui pelatihan vokasional, menemukan faktor pendukung dan penghambat, serta mengetahui solusi yang dilakukan lembaga. Informan ditentukan secara purposive, pengumpulan data dilakukan dengan wawancara dan data yang dikumpulkan melalui pemanfaatan dokumen yang terkait dengan pemberdayaan serta data yang terkumpul tersebut dianalisis secara kualitatif. Artikel ini menunjukan bahwa pemberdayaan adalah suatu proses mengembangkan penyandang disabilitas fisik dari keadaan tidak atau kurang berdaya menjadi mempunyai daya. Pelayanan di dalam lembaga dibatasi karena seiring dengan perkembangan masyarakat, peraturan dan kebijakan dari Kementerian Sosial serta terjadinya pergeseran pola pelayanan sosial dari “charity-based” ke hak warga Negara, dari “institutional-based” ke “family/community-based”. Demikian pula model pelayanan rehabilitasi sosial juga mengalami perkembangan. Namun tidak dapat dipungkiri bahwa dalam beberapa aspek pelayanan masih dijumpai kendala yang mempengaruhi kinerja pelayanan antara lain kepada: a. Lembaga, agar lebih fokus dalam proses pelaksanaan rekruitmen, maka perlu dilakukan pemetaan data secara komprehensif terlebih dahulu sebelum melakukan kegiatan sosialisasi maupun pendaftaran calon penerima manfaat di daerah, sehingga dapat dijaring calon penerima manfaat yang lebih banyak lagi secara kuantitas. Selain itu perlu menyempurnakan serta meningkatkan secara kuantitas dan kualitas dalam proses pelaksanaan rekruitmen serta perlu menambah jangkauan ke pelosok daerah lain yang selama ini belum pernah diadakan kegiatan rekruitmen. Sedangkan Kegiatan pemberdayaan terhadap penyandang disabilitas fisik hendaknya tidak hanya ditujukan untuk peningkatan pengetahuan dan keterampilan kerja semata, tetapi juga diarahkan untuk perubahan sikap dan perilaku penerima manfaat. b. Petugas asessmen sebagai aset utama lembaga belum berlatar belakang pekerjaan sosial dan memiliki kompetensi sebagai petugas assesmen. Proses pelaksanaan assesmen yang diselenggarakan secara kesisteman telah berjalan dengan baik dengan menilai aspek fisiologis, psikologis, sosiologis dan vokasional, namun perlu didukung peralatan yang terstandard dan lengkap serta petugas assesmen yang lebih professional baru kemudian menggunakan metode work sample apabila petugas tidak mampu mengungkapkan kapasitas penerima manfaat dengan menggunakan alat ukur tersebut.

Published: February 2023

Background: The symptoms of pulmonary sarcoidosis may lead to fatigue, excessive daytime sleepiness, poor sleep quality, and a decrease in quality of life in these patients. Objectives: This study was designed to evaluate the effects of oral melatonin on sleep disorders of patients with pulmonary sarcoidosis. Methods: A randomized, single-blinded clinical trial was conducted on patients with pulmonary sarcoidosis. Eligible patients were randomly allocated into melatonin and control groups. Patients in the melatonin group were given 3 mg melatonin one hour before bedtime for three months. Sleep quality, daytime sleepiness, fatigue status, and quality of life were assessed applying General Sleep Disturbance Scale (GSDS), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Fatigue Assessment Scale (FAS), and the Patient-Reported Outcomes Measurement Information System (PROMIS), respectively, as well as the 12-item Short Form Survey (SF-12) scores at the baseline and three months after treatment. Results: There was a significant change in the GSDS (P < 0.001), PSQI (P < 0.001), ESS (P = 0.002), and FAS (P < 0.001) scores, which were decreased, compared to those of the control group. After intervention¸ global physical health and global mental health raw scores were improved comparing to the control group (P = 0.006, P = 0.02, respectively). The 12-item Short Form Survey evaluation showed that there was a significant difference between the melatonin (3.38 ± 4.61) and control (0.55 ± 7.25) groups in PCS-12 score after three months of therapy (P = 0.02). Conclusions: Our findings showed that supplemental melatonin could significantly improve sleep problems, quality of life, and excessive daytime sleepiness in sarcoidosis patients.
Current Status of Peptide Medications and the Position of Active Therapeutic Peptides with Scorpion Venom Origin
Authors: Baradaran Masoumeh
Published: February 2023

: Peptides are highly potent, selective, and relatively safe therapeutics. Over the past two decades, natural peptides have been obtained, studied, and eventually approved by the Food and Drug Administration (FDA) due to advancements in identification, production, modification, and analytical technologies. Some peptide therapeutics has been derived from the venom gland of venomous animals, including snake, leech, lizard, snail, and scorpion. Scorpion was identified as a reservoir of important peptides with pharmaceutical properties. The scorpion uses these peptides for capturing prey and defense. However, their pharmacological properties in treating different diseases, including cardiac problems, autoimmune and infectious diseases, and diverse cancers, have been confirmed. Ion channel modifiers are the greatest components of the scorpion venom glands. Due to advances in proteomic and transcriptomic approaches, the identification of new scorpion venom peptides is steadily increasing. In this review, we tried to represent the current status of peptide medicines and describe the last peptide medications approved by FDA in 2022. Moreover, we will further explain potent peptides originating from scorpion venom, which have gone through important steps to be approved.

Se tenir à distance des mots. Détournement, prescription et disposition à l’action chez Nathalie Quintane
Authors: Cauchin Quentin
Published: February 2023

Resume :Interroger la dimension prescriptive de l’œuvre de Nathalie Quintane peut paraître surprenant tant l’autrice s’obstine, depuis une vingtaine d’années maintenant, à traquer les assertions, les phrases toutes faites et tout ce qui, dans le langage, modèle le prêt-à-penser ou comporte une part de normativité. L’article se concentre sur deux textes, Que faire des classes moyennes ?, paru en 2016, et Les enfants vont bien, en 2019, qui tournent en dérision les conventions des formes pédagogiques pour dénoncer les soubassements idéologiques des discours dominants. Il fait de la critique discursive mise en œuvre par Quintane une des modalités d’un processus littéraire d’apprentissage, désirant accroître les implications politiques de l’expérience de lecture au sein des pratiques ordinaires de parole.

Published: February 2023

Objective: To evaluate antihyperlipidaemic activity  of  methanolic  extract  of  seeds  of  Cuminum cyminum L. in hyperlipidaemia in rabbits.

Methods:  This study was conducted in Pharmacology Department of University of Karachi; the duration of study was 30 days.  Healthy  rabbits  were  taken  and  hyperlipidaemia  was  induced  by  giving  high cholesterol diet for four weeks. All animals were divided into three groups, with each group having ten rabbits (n=10).The methanolic extract of seeds of Cuminum cminum L.  was  dissolved  in  an organic solvent DMSO (Dimethyl-sulphoxide). One group was control-receiving DMSO,  while  second  group received methanolic extract of Cuminum cyminum L.  (MECC)  500mg/kg  and  third  group  re-  ceived Atorvastatin 2mg/kg.Blood samples were taken at 0, 15th and 30th day of dosing and sent for the tests to Punjwani Centre for Molecular medicine & Drug research (PCMD) Diagnostic Laboratory.

Results:  The group that was given methanolic extract of  Cuminum Cyminum L.  showed  decrease  in  High Density Lipoprotein (HDL) - cholesterol ratio (7.62 ± 4.01 to 4.45 ±  3.23)  (p<0.05),  cholesterol (208.54 ± 5.71 to 130.26 ± 5.72) (p<0.01), triglyceride (158.75 ± 5.23 to 136.14 ± 8.72) (p<0.001) and Low Density Lipoprotein (LDL) (168.17 ± 5.43  to  135.42±11.39)  (p<0.001)  and  the  group  that  was  given Atorvastatin showed HDL-cholesterolratio(7.33 ±  3.27  to  3.12  ±  2.19)  (p<0.01),  cholesterol (208.11  ± 6.72  to  98.75  ± 3.77)  (p<0.001),  triglyceride  (157.21  ± 6.72  to  141.25  ± 6.84)  (p<0.01) and Low Density Lipoprotein (LDL) (167.25 ± 4.32 to 127.67 ± 10.96) (p<0.001) towards its normal levels from day 0 to 30th day of dosing on comparison to control, whereas triglycerides were significantly de- creased by extract than atorvastatin.

Gastroesophageal Reflux Disorder: Difficulties in Diagnosis and Treatment in Infants
Authors: Madia Kazmi  , Haider Ali  , Sina Aziz
Published: February 2023

Gastroesophageal Reflux Disease (GERD), as the name suggests, is  a  condition  wherein  there  is  a reflux of the contents of the stomach towards the oesophagus, which eventually leads to pathological changes in the oesophagus itself if not managed at an early stage appropriately. Here we present a case of a 6 month old infant who presented with a history of repeated cough, fever, difficulty in breathing and poor weight gain. Various  physicians  saw  the  infant,  however,  due  to  worsening  symptoms  and no relief, the infant presented to the paediatric emergency department of the  Abbasi  Shaheed  Hospital. An initial management for pneumonia was done  but  there  was  a  persistence  of  symptoms even after clearance of the pneumonic patch. An upper gastrointestinal (GI) imaging  study,  including Barium swallow and fluoroscopy was done to evaluate the anatomy of the upper gastrointestinal tract    which showed mild to moderate reflux but no strictures, stenosis, achalasia or gastric outlet obstruction. The infant was managed via medical intervention and lifestyle counselling. On follow-up, the infant improved clinically and gained weight. It is extremely important in such  cases  to  have  a  strong clinical suspicion of Gastroesophageal reflux (GER) which may lead to GERD, while assessing  the  patient's signs and symptoms and to  support  the  diagnosis  of  GERD  with  appropriate  investigations and management.

Authors: Mehreen Iqbal  , Syeda Rabia  , Samreen Fakeer Muhammad
Published: February 2023

Objective: The objective of this study was to determine the frequency of pelvic pain and per vaginal bleeding, in the first trimester of pregnancy.

Methods: A total of 150 pregnant women 18 to 35 years in first trimester were recruited in this cross- sectional study, conducted from  July  2015  to  July  2016.  Non-probability  sampling  technique  was   used to collect the data. The collected information from  patients  were  entered  in  pre-designed  proforma after taking informed consent. Data was analysed by using SPSS version 20.

Results: The average age of the patients was 26.33 ± 4.23 (range 18-35) years. Frequency of pelvic pain and per vaginal bleeding in first  trimester  of  pregnancy  was  observed  in  29.33%  (44/150)  and 12% (18/150) respectively. Stratification analysis was performed and it was observed that rate of pelvic   pain and per vaginal bleeding was not  statistically  significant  among  different  age  groups.  Rate  of  pelvic pain was significantly high in women with primigravida as compare to multigravida (p=0.003).

Conclusion: We found in our sample a significant number of women  experiencing  pelvic  pain  and  vaginal bleeding in first trimester of their pregnancy. The practitioner must employ sound clinical and diagnostic skills in the management of the patient as early pregnancy complications  can  cause  sig-  nificant distress for some women and their partners.

Nephrocalcinosis and its outcome has been widely  studied  in  the  preterm  population.  There  is  a  paucity of data regarding nephrocalcinosis in term babies. Prospective case series, in which ten neonates were included in the study from November 2013 and April 2014. All neonates with nephrocalci nosis diagnosed by  ultrasound  of  kidney,  ureters,  bladder  (KUB)  done  antenatally  or  during  evaluation for urinary tract infection in neonates with  hyperbilirubinemia/sepsis  were  included.  All   preterm  neonates  and  neonates  with  congenital  urinary  tract  anamolies  were  excluded  from  this  case series. Cases were followed to know the outcome of the condition by follow-up ultrasonography. Follow-up ultrasound kidneys after 2-4 weeks revealed no evidence of nephrocalcinosis in majority of the cases. In one case, hypocitrateuria was documented. Hence, nephrocalcinosis is a transient phe- nomenon but needs close monitoring with follow-up scans.

In this case series we investigated nephrocalcinosis with early follow-up and ultrasound of kidneys to compare the baseline findings.This helped us in defining absolute outcome to the parents in case of neonatal nephrocalcinosis. Moreover, it helped our fellows in making timely diagnosis and proper counselling.

Published: February 2023

Objective: To  assess the knowledge and attitude about the emergency contraceptives among nursing and midwifery students in tertiary care hospitals in Karachi.

Methods: This cross-sectional study was carried out in the nursing school of Dow University Hospital and & Civil Hospital Karachi. Duration of the study was January 2017 to June 2017. All nursing and midwifery students, after verbal consent, were interviewed face-to-face using a pretested structured questionnaire. The  questionnaire  was  developed  to  assess  knowledge  and  attitudes;  the  way  in  which the respondents think and behave  towards  emergency  contraceptives  (EC).  Some  questions  were objective in nature with 'Yes' or 'No' options, whereas few questions were of multiple choice. The variables were age, educational level, religion, marital status, source of  information,  EC  types  and  method of use, side effects and source of availability and the attitudes of participants towards the use of EC (11 items). The data was recorded in MS  Excel  (2010  version).  Data  analysis  was  done  by  SPSS 16. Mean and SD of age was calculated while the categorical variables were analysed by using frequency and percentages. Chi-square test was applied and significance of test was decided at p-

value £0.05.

Results: There were 149 respondents out of the 165 targeted population.  The  response  rate  was  90.30% among nurses and midwives working in public sector of health care system in Karachi, Pakistan. The mean age of  the  respondents  was  20.63  ±  1.69  years.  Most  respondents  were  between  the ages of 20-35 years; 98 (65.8%),  with  majority  having  educational  level  of  matriculation;  66  (44.3%). There were nurses and midwives with optimum knowledge  for  EC  based  on  the  scale  of  having three or more correct responses out of four items. The  best  positive  attitude  was  scaled  by correct response of seven or more items out of eleven. The association of demographic factors with attitude towards EC was only significant at p-value£ 0.05 among married students.

Conclusion:  Awareness  regarding  EC  with  optimgum  knowledge  and  positive  attitude  was  found  in about two-thirds of nurses and midwives. Information must be spread through media and training to remove barriers and misconceptions among nurses and midwives.

Objective: Evaluation and comparison of anti-epileptic activity of methanolic extracts of seeds of Cuminum cyminum L. and Centratherum anthelminticum L. in strychnine-induced seizure model.

Methods: The study was conducted in the Department  of  Pharmacology,  University  of  Karachi.  After  15  days of dosing, experiment was performed. A total of 40 healthy mice were selected from animal house of  the Pharmacology department, University of Karachi, and were equally divided into four groups. Group 01 was on DMSO (dimethyl sulphoxide) organic solvent as control; Group 02 was on methanolic extract of  Cuminum cyminum L. (500 mg/kg); Group 03 was on methanolic extract of Centratherum anthelminticum L. (200 mg/kg) and Group 04 was on reference drug diazepam (3 mg/kg). On the day of experiment, after giving doses of DMSO, methanolic extract of Cuminum cyminum L., methanolic extract of Centratherum anthelminticum L. and diazepam,  respectively  to  all  groups,  strychnine  was  administered  and  animals  were observed for latency period and duration of Mortality rate was also evaluated.

Results: Group 02 and 03, receiving methanolic extracts of Cuminum cyminum L. and Centratherum anthelminticum L. showed significant seizure protection as observed by delayed seizure onset (p <0.001) and decreased total duration of convulsions in groups 02 and 03 (p£ 0.01, p£ 0.05) respectively. The mortality rate also decreased significantly (p £ 0.05) in comparison with group 01.

Conclusion: Anticonvulsant activity of methanolic extracts of Cuminum cyminum L. and Centratherum anthelminticum L. could be due to their antioxidant activity and further enhanced by potentiation of GABAergic and glycinergic activity. Further studies are required to confirm exact mechanism of action.

Objective: The aim of this study was to correlate the linear and angular measurements between lateral cephalogram and lateral photographs.

Method: An observational cross-sectional study was carried out at the department of orthodontics, Karachi Medi- cal and Dental College, Karachi, Pakistan. The study was conducted for six months from 30th  October  2016  to  30th April 2017. Inclusion criteria included no previous orthodontic or surgical treatment, having all six maxillary anterior teeth present, no craniofacial trauma and no neurologic disturbances. Exclusion criteria includes those patients in whom radiation exposure cannot be given. A sample of 179 patients was selected which included 49 males and 139 females and they were examined by  the  researcher. A lateral  cephalogram  and  a  digital single lens reflex (DSLR) camera was used to obtain the linear and angular craniofacial measurements.  A  standard lateral cephalogram and standardized lateral photograph of each patient was taken respectively and    then their measurements were taken with respect to  different  variables.  Cephalogram  measurements  taken  were as follows: (1) SNA (sella-nasion to A point); (2) SNB (sella-nasion to B point); (3) SNMP (sella-nasion to mandibular plane); (4) total facial height; (5) lower facial height; and (6) mandibular  length.  Whereas photo- graphic measurements taken were as follows: (1) TN'A' (angle between tragion-soft tissue nasion line and soft tissue nasion-soft tissue A-point line); (2) TN'B' (angle between tragion-soft tissue nasion line and soft tissue nasion-soft tissue B-point line); (3) FH'MP' (angle between soft tissue Frankfort plane and soft tissue mandibular plane); (4) CP'MP' (angle between cranial plane and soft tissue mandibular plane); (5) lower facial height; (6) total facial height; (7) mandibular length; and (8) chin projection. The lateral cephalogram and lateral photo- graphs measurements of patients were compared respectively and the Pearson correlation between them was calculated using SPSS 20.

Results: The results obtained showed that there was a moderate correlation between SNA and TN'A', SNB and SN'B', SNMP and FH'MP' whereas the correlation between facial heights and lower facial heights was very weak and CP and CP'MP' holds no correlation between them. All the correlations found between were statistically sig- nificant and had linear, positive co-relation between them.

Conclusion: Photographs can be used in place of lateral cephalogram X-rays for diagnostics and treatment planning.

Authors: Muhammad Jameel Ashraf  , Syed Kashif Abbas  , Atika Sher
Published: February 2023

Objective: To determine the diagnostic accuracy of serum procalcitonin levels (PCT) by  taking  blood culture as gold standard.

Methods: This was a cross-sectional study  conducted  in  neonatal  intensive  care  unit  (NICU)  of  Liaquat National Hospital, Karachi over a period of six months from June 2017 to December 2017. A total of 141 babies were enrolled in the study that had evidence of neonatal sepsis. Non-probability consecutive sampling was the technique used in our study for sample collection.  Later  on,  after  completion of data of required sample, a data base was developed on SPSS for windows version 22.0 for data analysis. Mean, median and standard deviation were calculated for continuous while fre- quency along with percentages was drawn for qualitative variables. Pearson Chi-square test (c2) was applied on all qualitative variables by taking p-value <0.05 as significant. Finally, the diagnostic accuracy of serum procalcitonin levels in neonatal sepsis was calculated in terms of sensitivity, specificity, positive predictive values and  negative  predictive  values  using  blood  culture  as  gold  standard. 

Results: Of 141 neonates, 68 were males and 73 were females which constitutes 48.2% and 51.8%, respectively. The mean weight of neonates was 2.49 ± 0.55 kg, while mean height and FOC (frontal- occipital circumference) were found to be 46.22 ± 3.17 cm and 33.29 ± 1.41 cm, respectively.  The sensitivity of PCT in this study was found to  be  70.90%  while  the  specificity  was  77.90%.  Further-  more, positive predictive value (PPV) and negative predictive value (NPV) accounted for 67.24% and 80.72%, respectively.

Conclusion: Although blood culture is the gold standard method to diagnose neonatal sepsis in neo-   nates, however PCT has also shown good accuracy with quick results in diagnosing neonatal sepsis in this study. The early use of PCT in neonatal infection may definitely help us limiting number of neonates putting on antibiotics due to suspected risk of infection.

Objective: To evaluate chronic back pain improvement after single dose of epidural steroid plus  li-  gnocaine injection in both sexes.

Methods: A consecutive cases series of 65 patients having age of ³18  to 80 years and of both sexes from one institution were retrospectively studied. The study was conducted from January 2011 to July It was designed to evaluate the pain improvement after single dose of epidural steroid plus li- gnocaine injection with lumbar interlaminar technique in chronic back pain patients. Patients were di- vided into two groups, to assess the effectiveness of pain relief  following  the  injection  in  between  different age groups with Magnetic Resonance Imaging (MRI), evidence of lumber disc prolapse and non-responder to oral medication were included. Those having  red-flags  (neurosurgical  deficit)  for  surgical intervention were excluded from  the  study.  Chronic  back  pain  patients  were  treated  with  single dose of lumbar interlaminar epidural steroid  plus  lignocaine  injection.  Follow-up  visits  were  carried out to assess pain reduction by patient perception as well as decrease requirement of oral medication.

Result: Out of all 65 patients, 28 were male. Mean age of 50.04 ± 14.26 range 18-80 years. After the epidural steroid plus lignocaine injection, all patients of both the groups  showed  decrease  in  pain  severity, evidenced by both patient perception  and  decrease  requirement  for  oral  medication.  There  was no gender difference. Two patients needed second injection  after  interval  of  6  months.  One  fe- male developed spinal anaesthesia after the injection, who recovered within 1 week.

Conclusion: This study concludes that epidural  injection  of  steroid  plus  lignocaine  is  effective  and  safe in relieving chronic back pain in both sexes.
Traumatic Diaphragmatic Hernia in a 40-Year-Old Lady after 34 Years of Trauma
Authors: Hajrah Hilal Ahmed  , Saliha Afzal  , Muhammad Jamaluddin
Published: February 2023

The diaphragm is a sheath made of muscle and tendon that separates the thoracic cavity from the ab- dominal cavity. A diaphragmatic hernia is the protrusion of intra-abdominal contents through an abnormal opening in the diaphragm. Acquired diaphragmatic tears are rare and occur mainly due to direct penetrating injury to the diaphragm or, less commonly, secondary to blunt abdominal trauma, causing her- niation of the abdominal contents into the thorax resulting in a condition known as post-traumatic diaphragmatic hernia. Signs and symptoms include orthopnea, dyspnea, diminished breath sounds on the side of the rupture and audible gut sounds in the chest. We report a case of a 40-year-old woman with a 34-year-old history of an unmanaged road traffic accident who presented with  a  complain  of  gradual in onset shortness of breath, which when approached surgically, revealed to be due to an absent left sided diaphragm. Upon diagnosis, successful primary hernia mesh repair was performed.

Published: February 2023

Objective: To establish reference range for  the  diameters  of  arteries  forming  the  Circle  of  Willis  (CoW) and to correlate it with age.

Methods: This cross-sectional study  was  conducted  at  the  Radiology  Department  from  January  to  July 2018. It comprises of patients referred for MR imaging of brain without any manifestation of cere- brovascular diseases. Patients who were  claustrophobic  or  had  a  history  of  atherosclerosis,  vasculi-  tis, thrombus, aneurysm, arteriovenous malformation (AVM), intracranial tumour, diabetes  and  hypertension were excluded. 300 individuals comprising both males and females with mean age of 45 ± 11.6 (years) were recruited via non-probability  sampling  technique.  Three-dimensional  Time  of  Flight (TOF) Magnetic Resonance Angiography (MRA) was performed. Diameters of  all  component  vessels forming the Circle of Willis were measured.

Results: The diameter of the anterior cerebral, anterior communicating, internal carotid, posterior communicating, posterior cerebral and basilar arteries were found to be 1.51 ± 0.28 mm, 1.05 ± 0.37 mm, 3.69 ± 0.23 mm, 1.10 ± 0.11 mm, 1.85 ± 0.23 mm, 3.00 ± 0.11 mm respectively. Spearman correlation demonstrated that the diameters of the arteries were significantly correlated with age in different ways. Significant moderate positive  correlations  of  internal  carotid  and  basilar  artery  diameters  were seen with age. Significant weak negative correlations were seen in anterior and posterior cerebral arteries. Significant very weak negative correlations were seen in anterior and posterior commu- nicating artery diameters and age.

Conclusion: The normal reference values for vessels diameter of CoW were determined in general population living in Karachi.  Diameter  of  the  arteries  showed  statistically  significant  correlation  with  age in different ways. Knowledge of calibre of the arteries is helpful in cerebrovascular surgeries and radiological neuro interventions.
