General Medicine - Abstract
OBJECTIVES Haemodialysis (HD) is a form of renal replacement therapy commonly prescribed for chronic kidney disease (CKD) patients. However, it is not without deleterious haemodynamic responses which may occur either during or immediately after the termination of the procedure. These may include hypotension or hypertension. The objective of this study was to determine the frequency of intradialytic blood pressure changes in chronic kidney disease patients on maintenance hemodialysis.METHODOLOGY Patients with chronic kidney disease on maintenance hemodialysis were enrolled. Predialysis and immediate post dialysis blood pressure was recorded. Increase in postdialysis blood pressure by >20mmHg was called intradialytic hypertension and decrease by >20mmHg was called intradialytic hypotension.RESULTSA total of 203 patients on maintenance hemodialysis were enrolled. Age of the patients ranged from 18 to 50 years. Mean age of the patients was 39.80 ± 5.245 years. Male to female ratio was 1.8:1. Intradialytic hypotension was observed in 36 patients (17.7%) while intradialytic hypertension was observed in 22 patients (10.8%).CONCLUSIONIntradialysis blood pressure fluctuations such as hypotension and hypertension are common complications during hemodialysis. Intradialytic hypotension is more frequent.

- Abstract
Low back pain (LBP) is pain in the lower part of the trunk, a highly prevalent and disabling condition globally. Clinical management for acute LBP and lumbosacral radiculopathy patients recommends first-line treatment consisting of education, support, and simple analgesics. This study evaluated the short-term alexander technique and core stability exercises versus the McKenzie method in treating lumbosacral radiculopathy. A randomized control trial with four weeks of follow-up was conducted from March 2022 to November 2022, consisting of a sample size of 20. Eligible participants were assigned a treatment protocol based on the McKenzie or Alexander technique for four weeks. The p-value was noted as greater than (0.05 non-significant), so the null hypothesis failed to reject it, meaning there was no significant difference between the Alexander technique and McKenzie method in treating lumbosacral radiculopathy. McKenzie was slightly more effective and responded from the first day to the end of the treatment session, but the reoccurrence of LBP was frequent due to weak muscles, poor working posture, and weight lifting in daily life activity. Alexander technique and core stability exercises response was slow in the first two weeks; after two weeks, both Alexander and McKenzie methods showed similar responses but no reoccurrence in Alexander-technique.

- Abstract
Cholangitis is an inflammation of the biliary tree due to Gallstones. The port region is susceptible to postoperative infections when a patient has excessive wounding and a microorganisms isolated from spontaneously procured tissue or fluid inside the upper cut. Objectives: To analyze the frequency of port site infection (PSI) and to assess variables influencing PSI following laparoscopic cholecystectomies. Methods: This research was carried during 2022 in two hospitals in Peshawar(Pakistan). Only 55 of the 907 patients who had PSI after going through LC surgeries were included and were kept under observations for six months. Data were collected by questionnaire, imported into the SPSS for statistical analysis. Descriptive statistics and Chi-square test were used for association between variables. Results: 34 patients out of 55 had CC, whereas 21 patients underwent surgery following an AC and became infected. Following LC, PSI frequency were lower than after open cholecystectomy. Majority of patients were women. Only five patients, based on the PSI, got an infection at the lateral ports, whereas 11 patients and 39 patients respectively, developed infections at the umbilical and epigastric ports. PSI came from majority of the female patients showing a significant association in frequency of PSI in relation to gender. Conclusion: Females tend to have high PSI rates and frequent epigastric port PSIs.

Organic framework materials, particularly metal-organic frameworks (MOFs), graphene-organic frameworks (GOFs), and covalent organic frameworks (COFs), have led to the revolution across fields including catalysts, sensors, gas capture, and biology mainly owing to their ultra-high surface area-to-volume ratio, on-demand tunable crystal structures, and unique surface properties. While the wet chemistry routes have been the predominant synthesis approach, the crystal phase, morphological parameters, and physicochemical properties of organic framework materials are largely affected by various synthesis parameters and precursors. In this work, we specifically review the influences of synthesis parameters towards crystal structures and chemical compositions of organic framework materials, including selected ligand types and lengths, reaction temperature/solvent/reactant compositions, as well as post-synthesis modification approaches. More importantly, the subsequent impacts on the general electronic, mechanical, surface chemical, and thermal properties as well as the consequent variation in performances towards catalytic, desalination, gas sensing, and gas storage applications are critically discussed. Finally, the current challenges and prospects of organic framework materials are provided.

Demand for electric kickboards is increasing specifically in tourist-centric regions worldwide. In order to gain a competitive edge and to provide quality service to customers, it is essential to properly deploy rental electric kickboards (e-kickboards) at the time and place customers want. However, it is necessary to study how to divide the region to predict electric mobility demand by region. Therefore, this study is made to more accurately predict future demand based on past regional customers’ electric mobility demand data. We have proposed a novel electric kickboard demand prediction in spatiotemporal dimension using clustering-aided bagging regressor. We have used electric kickboard usage data from a Jeju, South Korea-based company. As a result of the experiment, it was found that the accuracy before using clustering-based bagging regressor and when the region was divided by the clustering method, the performance was improved, and we have achieved a regression score R 2 of 93.42 using our proposed approach. We have compared our proposed approach with other state-of-the-art models, and we have also compared our model with different other combinations of bagging regressors. This study can be helpful for companies to meet the user’s demand for a better quality of service.

General Medicine - Abstract
The insurance agreement is a significant issue of Islamic jurisprudence which has concerned numerous arguments and deliberations. Shari‘ah researchers, economists, and experts have categorically discussed their views from a Shari‘ah stands point. A number of scholars are opposed to the idea of modern insurance. They highlight objectionable elements like interest, gambling, and uncertainty in insurance. On the other hand, some scholars say nothing incorrect with insurance. According to them, an insurance contract is a valid contract from the Shari‘ah point of view because it is based on Islamic values ofcollaboration and mutual help. Many international conferences and seminars had been organized on said issue and were studied by collective fiqhi bodies and research organizations in different Muslim countries. This paper aims to review and analyze theverdict uphold in the conferences and the resolutions of research organizations about the shari'ah position of insurance as the collective opinion are always considered stronger than individual opinion. Resolutions of almost all well-known reputed fiqhi bodies were collected and analyzed. It is noted with surprise that although some scholars consider insurance permissible but all collective fiqhi bodies are unanimous on it impermissibility due to the involvement of prohibited elements found in this contract. These bodies also suggested the possible alternative to commercial insurance. `The 1992 report of the Council of Islamic Ideology Pakistan is the most comprehensive work on this subject and provides a detailed model based on the concept of Waqf.

Biomass energy is an important source of energy consumption. It is a renewable, abundant, and easily produced energy source. Its usage supports economies in reducing their dependence on fossil fuels and safeguards national energy security. The literature has extensively explored the association between biomass energy and environmental quality. However, the influence of biomass energy on sustainable development is overlooked. Against this background, the objective of this research study is to empirically scrutinize the utility of biomass consumption as a source of renewable energy for sustainable development in the Asian region. The panel data used in the study is taken from World Development Indicators and Global Material Flows Database for twenty-one Asian countries covering the time 1990-2017. Numerous econometric techniques are used in the study to ensure the robustness of the results. To know the nature of cointegration, the tests designed by Kao (1999) and Pedroni (1999) and second-generation tests, inter alia, have been employed. Furthermore, the cointegration test of Westerlund (2007), among others, is used in this research. Moreover, fully modified ordinary least square, dynamic ordinary least square, and Driscoll and Kraay methods are used to estimate the model. Finally, the conclusion of the study proves the argument that the consumption of biomass as a source of renewable energy has a significantly positive impact on sustainable development in the selected Asian economies. It is recommended that the region should efficiently utilize biomass to the maximum extent to travel on the path of sustainable development.

Plants have been used since ancient times as an important source of biologically active substances. Specific activities of these plant extracts are generally linked to the presence of secondary metabolites together with their phenolic contents. Present study aimed at investigating the total phenolic and flavonoid contents, and antioxidant activity of selected plants from five different families. The total phenolic content was measured using Folin-Ciocalteu assay and total flavonoid content by aluminum chloride colorimetric method. The antioxidant capacity was estimated by phosphomolybdinium assay. Our findings indicates that total phenolic content for methanolic extracts ranged from 27.07 to 59.11 mg GAE/g DW, and total flavonoid content ranged from 38.37 to 124.23 mg QE/g DW, with an antioxidant activity ranging from 55.82 to 129.06 mg AAE/g DE. Following trend was shown in the assessment of total phenolic and flavonoid contents: Rhazya stricta>Cicer arietinum>Solanum melongena>Solanum surattense>Solanum nigrum>Withania sominifera>Sisymbrium irio>Withania coagulans>Raphanus sativus>Fagonia indica>Brassica napus. While the antioxidant capacity followed the trend: Cicer arietinum>Solanum nigrum>Withania coagulans>Rhazya stricta>Raphanus sativus>Solanum melongena>Withania sominifera>Solanum surratense>Fagonia indica>Brassica napus>Sisymbrium irio. It is also seen that both wild and cultivated plants have higher medicinal value, which can be linked to the phenolic and flavonoid content, and antioxidant potential. Findings of the study revealed that wild plants possess higher phenolic content compared to cultivated plants, whereas cultivated plants had higher antioxidant activity.

Metal-organic frameworks (MOFs) with exceptional features such as high structural diversity and surface area as well as controlled pore size has been considered a promising candidate for developing room temperature highly-sensitive gas sensors. In comparison, the hetero-metallic MOFs with redox-active open-metal sites and mixed metal nodes may create peculiar surface properties and synergetic effects for enhanced gas sensing performances. In this work, the Fe atoms in the Fe3 (Porous coordination network) PCN-250 MOFs are partially replaced by transition metal Co, Mn, and Zn through a facile hydrothermal approach, leading to the formation of hetero-metallic MOFs (Fe2IIIMII, M=Co, Mn, and Zn). While the PCN-250 framework is maintained, the morphological and electronic band structural properties are manipulated upon the partial metal replacement of Fe. More importantly, the room temperature NO2 sensing performances are significantly varied, in which Fe2Mn PCN-250 demonstrates the largest response magnitude for ppb-level NO2 gas compared to those of pure Fe3 PCN-250 and other hetero-metallic MOF structures mainly attributed to the highest binding energy of NO2 gas. This work demonstrates the strong potential of hetero-metallic MOFs with carefully engineered substituted metal clusters for power-saving and high-performance gas sensing applications.

- Abstract
Background: In developed countries, colorectal cancer continues to rank as the third-most prevalent cancer to be reported and the third-most popular reason for cancer mortality in both genders. Objective: The purpose of the retrospective research was to compare the operational parameters and short-term oncological effects of laparoscopic surgery (LS) with traditional open surgery (OS) in colorectal cancer patients in our hospital. Methods: In this study, 148 patients who underwent CRC surgery between January 2020 and January 2022 at the Medical Teaching Institute (MTI) Peshawar, Pakistan's Khyber Teaching Hospital and Hayatabad Medical Complex Hospital were included. 64 people who had all had LS were included in the study. On the other hand, 84 people who had had OS were randomly selected from groups of people who were of the same gender and age. Result: In the group undergoing OS, the median of dissected lymph nodes was 22.8 (9–35) and 3 (0–14), whereas, in the group undergoing laparoscopy, the median number was 21.56 (8–32) and 6.2 (0–9). For 13 (15.47%) patients undergone through and 9 patients (14.06%) undergone through laparoscopy, blood transfusions were necessary. Although the LS group's procedure took longer than the OS group, their time in the ICU, time to start feeding and duration of stay at the hospital were all shorter. Practical implication Importance Laparoscopic surgery has not been proven to be more effective than open surgery for patients with low rectal cancer. Conclusion: LS provides the benefits of a shorter hospital stay and fewer problems and delivers relatively adequate lymph node dissection.

Allah Almighty used revelation as a source of guidance for man which was revealed to the prophets and also endowed man with sound intellect. But one thing must be kept in mind in recognizing the beliefs, principles, and branches of religion, the revelation should be given primary status and intellect should be given secondary status and it should not be made the ruler. We see after the first century that many sects emerged, some of which made revelation the only standard and some the only intellect. The disadvantage of this disruption was that the sects began to quarrel with each other and the goal of defending one's own sect became real. At the same time, another sect emerged, founded by Abu Al۔ Mansur Maturidi, who gave intellect and revelation their own place in the interpretation of religion. The present study gives a brief overview of the Maturidia sect, its principles and rules in the expression of beliefs, their views on various issues, and its effects on the Muslim Ummah. As a result, the opinion of the Maturidia sect is moderate and appropriate. They do not use too much Inflation and deflation in expressing their beliefs. Moreover, this sect has left a profound intellectual impact on the Muslim Ummah which we see in the present era also.

- Abstract
Objective: The goal of this study is to determine the degree of CD4 expression in histopathologically confirmed cases of psoriasis using immunohistochemistry. Study Design: Cross-sectional/ Descriptive study Place and Duration: Pathology Department of North West School of Medicine (NWSM), Peshawar and Avicenna Medical and Dental College, Lahore for duration of six months April 2021 to September 2021. Methods: There were 80 patients of both genders with age 18-70 years were presented in this study. Informed written consent was taken from all the patients for detailed demographics including age, sex and body mass index. Psoriasis was diagnosed by taking skin biopsy of all the patients. Histopathology slides were made from paraffin-embedded sections of the whole skin biopsy. When examined in the 40x magnification field, the cases were classified as having light staining (4-10 capillaries), moderate staining (11-20 capillaries), or strong staining (21-28 capillaries). On the basis of histopathology, psoriasis was determined to be present when the following features were observed: hyperkeratosis, acanthosis, a munro's abscess, the extension of rete ridges, and abnormalities of the dermal vasculature. SPSS 24.0 version was used to analyze. Results: Majority of the patients in or study were males 55 (68.8%) and the rest were females 25 (31.2%) with mean age 35.51+19.61 years. Mean BMI of the patients was 24.23+11.34 kg/m2. Frequency of moderate staining of CD34 expression was high found in 50 (62.5%) cases, mild staining in 17 (21.3%) patients and 21-28 capillaries (strong staining) in 13 (16.3%) patients. According to histopathological findings hyperkeratosis, acanthosis, a munro's abscess, the extension of rete ridges, and abnormalities of the dermal vasculature majority had moderate (11-20 capillaries) staining of CD34 expression. Conclusion: We concluded in this study that the mild staining expression of CD34 was majority seen among patients of psoriasis. Psoriasis's enhanced cutaneous vasculature has been demonstrated by this crucial angiogenesis marker. As a result, it can be used to better understand the disease's histiogenesis.

General Mathematics - Abstract
In this research work, we proposed a Haar wavelet collocation method (HWCM) for the numerical solution of first- and second-order nonlinear hyperbolic equations. The time derivative in the governing equations is approximated by a finite difference. The nonlinear hyperbolic equation is converted into its full algebraic form once the space derivatives are replaced by the finite Haar series. Convergence analysis is performed both in space and time, where the computational results follow the theoretical statements of convergence. Many test problems with different nonlinear terms are presented to verify the accuracy, capability, and convergence of the proposed method for the first- and second-order nonlinear hyperbolic equations.

Cardiology and Cardiovascular Medicine - Abstract
Background Clostridium perfringens is a well-known cause of gas gangrene with a very high mortality rate. Multiple cases of internal organs have been reported in the literature; however, non-traumatic spontaneous gas gangrene due to C. perfringens with solely cardiac involvement in a patient without any risk factors has not been reported before. Case Summary A 52-year-old male presented to the emergency department with chest pain and exertional dyspnoea for three days. The patient was haemodynamically stable initially, and the physical examination was unremarkable. Initial laboratory workup revealed elevated D-dimer and troponin levels. Computerized tomography (CT) of the chest was negative for pulmonary embolism but showed a hypodense focus in the cardiac silhouette. Acute coronary syndrome protocol was initiated; however, invasive cardiac workup was negative. The patient had rapid clinical deterioration with development of respiratory failure, shock, and multiorgan failure within 24 h. A transesophageal echocardiogram demonstrated an abnormal echogenic focus, corresponding to CT chest area. Despite aggressive treatment, the patient passed away within 36 h. Later, the patient’s blood culture grew C. perfringens. A limited autopsy showed an abscess cavity in the interventricular septum, pathology of which revealed acute myocarditis and fibrinous pericarditis. Discussion Unlike other reported cases of C. perfringens with cardiac abscess, our patient had no known risk factors, and no other organs were involved. We conclude from this case that an air focus on the CT scan in the myocardium can be suggestive of a spontaneous gas gangrene of the myocardium, and the patients should be treated accordingly.

The most completed, comprehensive and the moderate ideal are the Ahadees and the Seerat of the Holy Prophet (ﷺ) that are the source of deliverance for the whole people till Qyamah. There is no sphere of life, any part of society, individual and community problem that comes out way in which we don’t find his Ahadees Mubarkah as ideal. The nearest observance was got by Sahaba e kiram, Taabeen, Taba Tabeen, Muhddiseen one after the other. They not only learned by heart after hearing him and acted upon it but also tried their best to make reach his quotes, utterance, sayings and acts. The one of them is Allama Bahqi (r.a) that devoted his life for serving the Elm e Hades. He also founded a unique literary mood and tried to perform his obligation while claiming it his obligation to preach and to make the religion eminent. He was the man who left behind him small and large books about one hundred parts. One did not left such a huge treasure of knowledge before him.

Purpose This study aims to examine the key entrepreneurial roles (financial literacy, risk tolerance and competency) in the financial performance of small and medium enterprises (SMEs) in Pakistan and the mediating effects of locus of control and spiritual and emotional quotients. Design/methodology/approach The study data was collected from 541 SMEs in Pakistan (the target population) through a survey and analysed with partial least squares structural equation modelling. Findings The findings revealed that the key entrepreneurial characteristics were positively related to locus of control and spiritual quotient and elevated the financial performance in entrepreneurship. It was also reported that locus of control and spiritual quotient mediated between key entrepreneurial characteristics and financial performance. In this regard, emotional quotient strengthened the existing relationships between key characteristics, locus of control and spiritual quotient. Practical implications This study highlighted sustainable implications for SMEs to develop an effective mechanism and improve financial performance through guidelines that emphasized entrepreneurial characteristics and behaviours towards positive entrepreneurial ventures. This study also enabled policymakers to design policies that catalysed SME performance in Pakistan. Originality/value This study contributed a novel concept of key entrepreneurial characteristics by introducing a characteristics tool kit. Consequently, information on a unique framework (by integrating entrepreneurial characteristics and financial performance) and literature on spiritual quotient and locus of control in entrepreneurship were enriched. Contributions to the regulatory focus theory and four-phase Rubicon model in the study context were also made.

- Abstract
Aim: Given the relevance of irresistible infections to the wellbeing of women, we intended to evaluate the current attentiveness, interest and relevance of the unresisted obstetrical and gynecological infection among the residents and residents of contemporary obstetrics and gynecology. Methods: Two independent assessments which deal with attention, appreciation. Sub-specialty premiums were also sent out to (1) an irregular 22 percent sample of residents in obstetrics and gynecology and (2) all Gynecology obstetrics mailed out. Results: More than two-thirds of the chief students in the scientific section were aware of the specialty and 68,2% respected compelling disease experts. About a third of the employees were attentive to the specialization. The formal training of clinical specialists in the field of intractable diseases was reported by thirty-six percent of chief residents. Conclusion: Pakistani obstetrics and residents of gynecology and leaders have little knowledge of the sub-specialty. There is an open specialty to formal instruction by practitioners skilled in the field for residents in irresistibly infected object ology and gynecology. These findings may lead to continuous enrollment efforts in obstetrical and gynecology sub-specialties of irresistible diseases.

This research explores Pakistani newspapers Editorials’ lexical, morphological, and social aspects of the coronavirus Pandemic in Pakistan under the light of the Critical Discourse Analysis angle. The focal idea is to discover the etymological decision and rhetorical questions utilized in a revealing pandemic, and how did the columnists shape readers' minds and thoughts through their words. The CDA has been used as a theoretical framework for analyzing the data. Information for this examination includes 15 Editorial randomly gathered from 100 newspapers in Pakistan. Results demonstrated the exploitation of terminologies has been shown inconvenience, fear of contagious disease, death, fear of touching, and outbreak among people. The bogus information was additionally found in newspapers. Contradiction among newspapers was found while presenting data. This social change brings ultimately a linguistic change in the world. The English language is the language of overcoming gaps among nations, but this time it had correspondingly ushered in a new vocabulary to the general populace. For instance, new vocabulary, acronyms, synonyms, compounding, etc. Social change is parallel to linguistic change, and it is a paramount theme of lexicography. The local newspapers advocated a massive outbreak of the coronavirus and expected a second wave of this pandemic that was frustrating for the educational sector on top. The newspaper editors manipulate thoughts through forceful lexis usage to influence the thought, and opinions of Pakistani people.

Cardiology and Cardiovascular Medicine - Abstract
Background Idiopathic chronic constrictive pericarditis (CP) is an uncommon yet very important clinical entity as prompt diagnosis and early treatment are affiliated with improved outcomes. We describe an uncommon case of CP with a series of textbook findings and received successful treatment with surgical pericardiectomy (SP). Case summary A 58-year-old male presented to the emergency department with exertional dyspnoea and anasarca. The past medical history was negative for infections like tuberculosis, viral, etc., connective tissue disease, prior cardiac surgery, human immunodeficiency virus, or any radiation therapy. The vital signs were within normal limits except mild hypoxia while the physical examination was consistent with congestive heart failure. Further investigations with laboratory testing, imaging with chest X-ray, computed tomography, echocardiogram, and invasive study with right heart catheterization were all consistent with idiopathic chronic CP. The patient underwent successful SP with significant improvement in clinical condition. Discussion This case highlights the classical signs and symptoms along with important diagnostic features of CP. It is uncommon to see all the classical features of CP in one patient as described in the above case. Familiarity with these findings is crucial to make the diagnosis as early treatment is affiliated with improved outcomes.

We present a case report of a right atrial myxoma first diagnosed on a transthoracic echocardiogram after telephone consultations held in lieu of face-to-face consultations during the first wave of the COVID-19 pandemic. The echocardiogram was requested on the second telephone consultation 3 months after an initial presentation with a dry cough and fatigue due to new symptoms of palpitations and shortness of breath raising suspicion of heart failure. Virtual consultations continue to replace face-to-face consultations to avoid unnecessary exposure to COVID and reduce health care costs. This case report focuses on the importance of obtaining a systematic history, identifying red flags, referring to appropriate specialties and requesting the right investigations for early diagnosis and management of conditions with serious complications.

Ultrathin transparent conductive oxides (TCOs) are emerging candidates for next-generation transparent electronics. Indium oxide (In2O3) incorporated with post-transition-metal ions (e.g., Sn) has been widely studied due to their excellent optical transparency and electrical conductivity. However, their electron transport properties are deteriorated at the ultrathin two-dimensional (2D) morphology compared to that of intrinsic In2O3. Here, we explore the domain of transition-metal dopants in ultrathin In2O3 with the thicknesses down to the single-unit-cell limit, which is realized in a large area using a low-temperature liquid metal printing technique. Zn dopant is selected as a representative to incorporate into the In2O3 rhombohedral crystal framework, which results in the gradual transition of the host to quasimetallic. While the optical transmittance is maintained above 98%, an electron field-effect mobility of up to 87 cm2 V-1 s-1 and a considerable sub-kΩ-1 cm-1 ranged electrical conductivity are achieved when the Zn doping level is optimized, which are in a combination significantly improved compared to those of reported ultrathin TCOs. This work presents various opportunities for developing high-performance flexible transparent electronics based on emerging ultrathin TCO candidates.
