    PMID: 29518343 DOI: 10.1177/1055665618758278
    OBJECTIVES: The aim of this study is to assess the treatment outcome of complete unilateral cleft lip and palate (CUCLP) patients using modified Huddart/Bodenham scoring system (MHB). To determine whether there is an association of congenital and postnatal factors with the treatment outcome.

    DESIGN: Retrospective observational study.

    SETTING: Two regional cleft-referral centers.

    MAIN OUTCOME MEASURES: In the current study, 101 pairs of dental models of non-syndromic CUCLP patients were retrieved from hospital archives. Each occlusal relationship from central incisor till the first permanent molars were scored except the lateral incisor. Sum of 10 occlusal relationships in each study sample gave a total occlusion score. The primary outcome was the mean total occlusion score.

    RESULTS: According to MHB, a mean (standard deviation) total occlusion score of -8.92 (6.89) was determined. Based on treatment outcome, 66 cases were favorable (grades 1, 2, and 3) and 35 cases were unfavorable (grades 4 and 5). Chi-square tests indicated, difference of cheiloplasty ( P = .001) and palatoplasty ( P < .001) statistically significant. Five variables-gender, family history of cleft, cleft side, cheiloplasty, and palatoplasty-were analyzed with a logistic regression model.

    CONCLUSIONS: Final model indicated that cases treated with modified Millard technique (cheiloplasty) and Veau-Wardill-Kilner method (palatoplasty) had higher odds of unfavorable treatment outcome.

    Ahmad N, Javaid A, Sulaiman SA, Ming LC, Ahmad I, Khan AH
    Braz J Infect Dis, 2016 Jan-Feb;20(1):41-7.
    PMID: 26626164 DOI: 10.1016/j.bjid.2015.09.011
    BACKGROUND: Fluoroquinolones are the backbone of multidrug resistant tuberculosis treatment regimens. Despite the high burden of multidrug resistant tuberculosis in the country, little is known about drug resistance patterns, prevalence, and predictors of fluoroquinolones resistance among multidrug resistant tuberculosis patients from Pakistan.
    OBJECTIVE: To evaluate drug resistance patterns, prevalence, and predictors of fluoroquinolones resistance in multidrug resistant tuberculosis patients.
    METHODS: This was a cross-sectional study conducted at a programmatic management unit of drug resistant tuberculosis, Lady Reading Hospital Peshawar, Pakistan. Two hundred and forty-three newly diagnosed multidrug resistant tuberculosis patients consecutively enrolled for treatment at study site from January 1, 2012 to July 28, 2013 were included in the study. A standardized data collection form was used to collect patients' socio-demographic, microbiological, and clinical data. SPSS 16 was used for data analysis.
    RESULTS: High degree of drug resistance (median 5 drugs, range 2-8) was observed. High proportion of patients was resistant to all five first-line anti-tuberculosis drugs (62.6%), and more than half were resistant to second line drugs (55.1%). The majority of the patients were ofloxacin resistant (52.7%). Upon multivariate analysis previous tuberculosis treatment at private (OR=1.953, p=0.034) and public private mix (OR=2.824, p=0.046) sectors were predictors of ofloxacin resistance.
    CONCLUSION: The high degree of drug resistance observed, particularly to fluoroquinolones, is alarming. We recommend the adoption of more restrictive policies to control non-prescription sale of fluoroquinolones, its rational use by physicians, and training doctors in both private and public-private mix sectors to prevent further increase in fluoroquinolones resistant Mycobacterium tuberculosis strains.

    PMID: 27022154 DOI: 10.4269/ajtmh.15-0871
    Geographical variations of snake venoms can result in suboptimal effectiveness of Indian antivenoms that are currently used in most South Asian countries. This study investigated the toxicity and neutralization profile of the venom and toxins from Pakistani spectacled cobra, Naja naja, using VINS polyvalent antivenom (VPAV, India), Naja kaouthia monovalent antivenom (NKMAV, Thailand), and neuro bivalent antivenom (NBAV, Taiwan). Cation-exchange and reverse-phase high-performance liquid chromatography fractionations followed by toxin identification through liquid chromatography-mass spectrometry (MS)/MS indicated that the venom comprised mainly of postsynaptic neurotoxins (NTXs) (long neurotoxins [LNTXs], 28.3%; short neurotoxins [SNTXs], 8%), cytotoxins (CTXs) (31.2%), and acidic phospholipases A2 (12.3%). NKMAV is the most effective in neutralizing the lethal effect of the venom (potency = 1.1 mg venom/mL) and its LNTX (potency = 0.5 mg toxin/mL), consistent with the high content of LNTX in N. kaouthia venom. VPAV was effective in neutralizing the CTX (potency = 0.4 mg toxin/mL), in agreement with the higher CTX abundance in Indian cobra venom. All the three antivenoms were weak in neutralizing the SNTX (potency = 0.03-0.04 mg toxin/mL), including NBAV that was raised from the SNTX-rich Taiwanese cobra venom. In a challenge-rescue experiment, envenomed mice were prevented from death by a maximal dose of VPAV (intravenous 200 μL) but the recovery from paralysis was slow, indicating the need for higher or repeated doses of VPAV. Our results suggest that optimal neutralization for Pakistani N. naja venom may be achieved by improving the formulation of antivenom production to enhance antivenom immunoreactivity against long and SNTXs.

    PMID: 10548305
    We evaluated the diagnostic sensitivity and specificity of two dot-enzyme-linked immunoassays (Typhidot and Typhidot-M; Malaysian Biodiagnostic Research SDN BHD, Kuala Lumpur, Malaysia), assessing IgG and IgM antibodies against the outer membrane protein (OMP) of Salmonella typhi, and the Widal test in comparison with blood culture in a consecutive group of children with suspected typhoid fever. Of 97 children with suspected typhoid fever, the disease was confirmed bacteriologically in 46 (47%), whereas 25 (26%) were considered to have typhoid fever on clinical grounds. An alternative diagnosis was made in 26 (27%). The Typhidot and Typhidot-M were superior to the Widal test in their diagnostic sensitivity and specificity, although values (sensitivity = 85-94% and specificity = 77-89%) were significantly lower than in other regional reports. The lower specificity of the Typhidot in our series may represent regional differences in the genomic structure and plasticity of the OMP of S. typhi and merits further evaluation of these tests in diverse geographic locations.

    Javaid A, Ahmad N, Afridi AK, Basit A, Khan AH, Ahmad I, et al.
    Am J Trop Med Hyg, 2018 06;98(6):1629-1636.
    PMID: 29611497 DOI: 10.4269/ajtmh.17-0936
    To evaluate the predictive value of time to sputum culture conversion (SCC) in predicting cure and factors associated with time to SCC and cure in multidrug-resistant tuberculosis (MDR-TB) patients, a retrospective study was conducted at programmatic management unit of drug resistant tuberculosis (TB), Peshawar. A total of 428 pulmonary MDR-TB patients enrolled at the study site from January 1, 2012 to August 31, 2014 were followed until treatment outcome was recorded. Survival analysis using Cox proportional hazards model and multivariate binary logistic regression were, respectively, used to identify factors associated with time to SCC and cure. A P value < 0.05 was considered statistically significant. Overall, 90.9% patients achieved SCC, and 76.9% were cured. Previous use of second-line drugs (SLDs) (hazard ratio [HR] = 0.637; 95% confidence interval [CI] = 0.429-0.947), ofloxacin resistance (HR = 0.656; 95% CI = 0.522-0.825) and lung cavitation (HR = 0.744; 95% CI = 0.595-0.931) were significantly associated with time to SCC. In predicting cure, sensitivities of SCC at 2, 4, and 6 months were 64.1% (95% CI = 58.69-69.32), 93.0% (95% CI = 89.69-95.52), and 97.6% (95% CI = 95.27-98.94), respectively, whereas specificities were 67.7% (95% CI = 57.53-76.73), 51.5% (95% CI = 41.25-61.68), and 44.4% (95% CI = 34.45-54.78), respectively. Furthermore, patients' age of 41-60 (odds ratio [OR] = 0.202; 95% CI = 0.067-0.605) and > 60 years (OR = 0.051; 95% CI = 0.011-0.224), body weight > 40 kg (OR = 2.950; 95% CI = 1.462-5.952), previous SLD use (OR = 0.277; 95% CI = 0.097-0.789), lung cavitation (OR = 0.196; 95% CI = 0.103-0.371) and ofloxacin resistance (OR = 0.386; 95% CI = 0.198-0.749) were significantly associated with cure. Association of SCC with cure was substantially stronger at 6 months (OR = 32.10; 95% CI = 14.34-71.85) than at 4 months (OR = 14.13; 95% CI = 7.92-25.21). However in predicting treatment outcomes, the combined sensitivity and specificity of SCC at 4 months was comparable to SCC at 6 months. Patients with risk factors for delayed SCC were also at high risk of unsuccessful outcomes.

    Khan AH, Israr M, Khan A, Aftab RA, Khan TM
    Am J Med Sci, 2015 Jun;349(6):505-9.
    PMID: 26030612 DOI: 10.1097/MAJ.0000000000000473
    BACKGROUND: Smoking is a risk factor not only for the development of cancer and coronary heart disease but also for tuberculosis (TB). The aim of this study was to determine the prevalence of smoking in patients with TB, identify demographic and clinical characteristics associated with smoking and to evaluate TB treatment outcomes in the smokers.
    METHOD: A retrospective cohort study of patients with TB was conducted at Khyber Teaching Hospital, Peshawar, Pakistan. All patients with pulmonary and extrapulmonary TB and those coinfected with HIV, hepatitis or diabetes mellitus were included in the study. The patients were categorized into smokers and nonsmokers. Treatment outcomes were evaluated by smear testing at the end of the treatment.
    RESULTS: Of 472 enrolled subjects, 68 (14.4%) were smokers. The prevalence of smoking among male and female patients with TB was 11.8% and 2.5%, respectively. Univariate analysis indicated that the gender, age group and marital status of patients with TB were associated with smoking. The results indicated that patient gender (P = 0.05), age: 15 to 24 years (P = 0.05) and age >55 years (P = 0.004) were risk factors associated with smoking among TB patients. Of the 68 smokers with TB, the treatment outcomes among 54 patients (79.4%) were unsuccessful. The treatment outcomes was statistically significantly associated with smoking (odds ratio: 2.58, P = 0.004).
    CONCLUSIONS: Findings from the current study proved smoking to be one of the main factors associated with the occurrence of TB and significantly reducing the outcomes of TB therapy.

    PMID: 31852359 DOI: 10.1080/10826084.2019.1701036
    Background: Although glue sniffing has been linked with significant morbidity and mortality, it is still under-researched and poorly recognized issue globally. Objective: A scoping review was performed to identify the factors and outcomes related to glue sniffing in India, Pakistan, Nepal and Bangladesh. Methods: Ten databases; Medline via Ovid, Google scholar, EBSCOhost (CINAHL Plus), ProQuest Central, PsycInfo, IndMED, Ovid Embase, Scopus, PubMed, and Science Direct were searched from their inception to January 2019 for both qualitative and quantitative studies examining any aspect of glue-sniffing. Studies published only in English language were included. Prevalence of glue-sniffing in SAARC region was the primary outcome measure. Findings: Of 8951studies screened, 344 were assessed for eligibility and 31 studies were included. The majority of the studies were conducted in India (15) and Pakistan (11). Meta-analysis of proportion, using random effects model, for both primary and secondary outcomes found that the highest incidence of glue sniffing was 57% (0.57, CI 95% 0.49-0.66) in India. The overall incidence of tobacco and naswar (snuff) as was 83% (0.83, 95% CI 0.80-0.86). Conclusions: The prevalence of glue sniffing, especially among street children, is alarmingly high and presents a challenge for health and social services for countries in SAARC region. More research work is required to examine long term impact of glue sniffing on physical and mental health.

    PMID: 32569533 DOI: 10.1080/10826084.2019.1657149
    Background: Areca nut (AN) and betel quid (BQ) chewing are ancient practices followed by an extensive proportion of the world's population. These practices are endemic in larger parts of South and Southeast Asia and selected Western Pacific countries. The prevalence of these habits varies across regions, age, gender, cultural practice, and socioeconomic status groups. Considerable variations exist between countries with respect to prevention/intervention programs, and policy guidelines of BQ usage. Objectives: (1) To provide an overview of the BQ chewing prevalence, practices, preventive interventions and policies in selected Asian and Western Pacific countries. (2) To explore the different terminologies associated with BQ use. Method: A narrative review of the current literature related to BQ, AN, and oral cancer was conducted by searching PUBMED, CINAHL, and GOOGLE databases. Results: The literature review revealed that the prevalence of BQ was found to be highest in Papua New Guinea, followed by Bangladesh, India, Pakistan, Myanmar and Sri Lanka. While, Cambodia, Malaysia, Indonesia and Taiwan had comparatively lower prevalence. Smokeless tobacco, BQ with tobacco, BQ without tobacco, AN were some of the terminologies used for BQ in various studies. Conclusions: The prevalence, and the interventional policies related to BQ and AN chewing habits varies widely among the selected countries. With the increasing awareness and association of BQ with oral cancer, there is a need to have better awareness, prevention and interventional strategies in place. We also found considerable variation in the use of terminologies associated with BQ.

    Stud Fam Plann, 1975 May;6(5):126-33.
    PMID: 1145693 DOI: 10.2307/1964747
    The objectives of this article are (1) review the contribution of traditional midwives to family planning communication in several Asian countries; (2) organize knowledge gathered from various studies into general guidelines for the most effective use of traditional midwives in family planning programs; and (3) present hypotheses for future research. In certain countries where pilot projects have tested the potential performance of traditional midwives in family planning programs, results have been encouraging. In other nations, more research is needed to determine the contribution traditional midwives can make to the family planning program.
    PIP: Traditional midwives are found in almost every village and in many urban neighborhoods in the developing world, delivering the majority of births in these areas. Several Asian nations have begun to recognize the potential contribution of traditional midwives to modern family planning and health programs. A total of about 17,000 traditional midwives have been trained as family planning recruiters in Indonesia, Malaysia, the Philippines, and Thailand. Because traditional midwives deliver a large number of births in Asian nations, the potential is great for them to reach large numbers of women regarding family planning -- particularly poor, illiterate women. There is much to be learned from the traditional health system and governmental health and family planning programs should join hands with these older systems.

  13. Fulltext Perception and attitude of general practitioners regarding generic medicines in Karachi, Pakistan: A questionnaire based study
    Jamshed SQ, Ibrahim MI, Hassali MA, Masood I, Low BY, Shafie AA, et al.
    South Med Rev, 2012 Jul;5(1):22-30.
    PMID: 23093896
    OBJECTIVES: In developing countries out-of-pocket payments (OOP) are as high as 80% of healthcare spending. Generic medicines can be instrumental in reducing this expenditure. The current study is aimed to explore the knowledge, perception, and attitude of general practitioners towards generic medicines in Karachi, Pakistan.
    METHODS: This exploratory, descriptive study was conducted on a sample of 289 randomly selected general practitioners who were dispensing at their private clinics in Karachi, Pakistan. The questionnaires were distributed and collected by hand. Data was entered to SPSS version 17. Fischer's exact test was applied to see the association between variables.
    RESULTS: A total of 206 questionnaires were included in the study. A response rate of 71.3% was achieved. Out of 206 respondents, 139 (67.5%) were male while 67 (32.5%) respondents were female. Close to three quaters of the respondents (n= 148; 71.8%) showed correct knowledge about generic medicines being a 'copy of the brand name medicines' and 'interchangeable with brand name medicines' (n= 148; 71.8%). In terms of safety, the majority of respondents (n=85; 41.26%) incorrectly understood that the generic medicines are less safe than brand name medicines. The total percentage of correct responses was seen in 53% of the respondents. More than half of the respondents agreed that locally manufactured medicines are of the same effectiveness as brand name medicines (n=114; 55.4%). Male practitioners with practice experience of 11-15 years showed positive perception towards the quality of multinational products. The Majority of respondents believed that their prescribing decision is influenced by medical representatives (n=117; 56.8%). More than three-quarters of the respondents expressed their wish to prescribe low cost medicines in their practice (n=157; 76.2%). More than one third of the respondents expressed their uneasiness to prescribe products from all local manufacturers (n=72; 35%).
    CONCLUSION: There were gaps identified in the knowledge of respondents. Although good perception and attitude were noted among the respondents, dissemination of information regarding generic medicines may perhaps strengthen generic prescribing. There is a need to introduce 'Quality by Design' concept in local manufacturing units. This, in turn, can inculcate confidence in prescribers towards locally manufactured generic medicines.

    PMID: 33540500 DOI: 10.3390/s21030974
    The early detection of damaged (partially broken) outdoor insulators in primary distribution systems is of paramount importance for continuous electricity supply and public safety. Unmanned aerial vehicles (UAVs) present a safer, autonomous, and efficient way to examine the power system components without closing the power distribution system. In this work, a novel dataset is designed by capturing real images using UAVs and manually generated images collected to overcome the data insufficiency problem. A deep Laplacian pyramid-based super-resolution network is implemented to reconstruct high-resolution training images. To improve the visibility of low-light images, a low-light image enhancement technique is used for the robust exposure correction of the training images. A different fine-tuning strategy is implemented for fine-tuning the object detection model to increase detection accuracy for the specific faulty insulators. Several flight path strategies are proposed to overcome the shuttering effect of insulators, along with providing a less complex and time- and energy-efficient approach for capturing a video stream of the power system components. The performance of different object detection models is presented for selecting the most suitable one for fine-tuning on the specific faulty insulator dataset. For the detection of damaged insulators, our proposed method achieved an F1-score of 0.81 and 0.77 on two different datasets and presents a simple and more efficient flight strategy. Our approach is based on real aerial inspection of in-service porcelain insulators by extensive evaluation of several video sequences showing robust fault recognition and diagnostic capabilities. Our approach is demonstrated on data acquired by a drone in Swat, Pakistan.

    PMID: 32415157 DOI: 10.1038/s41598-020-65065-2
    Intrauterine growth restriction (IUGR) is a clinical definition applied to neonates born with clinical features of malnutrition and in-utero growth retardation irrespective of their birth weight percentile. This study was aimed to determine the frequency of pulmonary hypertension (PH) in neonates with IUGR. In this descriptive cross-sectional study, we followed 96 neonates with IUGR (≤28 days) and 38 neonates without IUGR born in the department of the neonatal intensive care unit children hospital complex Multan, Pakistan. We analyzed certain factors such as gender, gestational age (GA) (weeks), birth weight (BW in kg), weight percentile (WP) for GA, meconium aspiration syndrome (MAS), birth asphyxia (BA) and respiratory distress syndrome (RDS) for pulmonary hypertension (PH) in IUGR and non-IUGR group. GA was measured by the Ballard scoring system. Echocardiography was performed for all patients by the pediatric cardiologist to measure pulmonary arterial (PA) pressure using Bernoulli's equation. Out of total 96 IUGR neonates, 33.3% (n = 32) suffered from PH, of which 65.3% (n = 18) were male and 43.7% (n = 14) were female. The percentages of IUGR neonates with BA, MAS and RDS were 34.4%, 18.8% and 22.9% respectively. The data were analyzed using the SPSS-16 software to test the statistical significance of the results. A p-value less than 0.05 was considered significant. When the chi-square test was applied, it depicted that MAS was significantly associated with PH in IUGR neonates (p = 0.0001) compared to non-IUGR neonates. Our findings suggested an increased chance of PH in IUGR neonates and MAS may be a strong factor.

    Drug-drug interactions (DDIs) may result in the alteration of therapeutic response. Sometimes they may increase the untoward effects of many drugs. Hospitalized cardiac patients need more attention regarding drug-drug interactions due to complexity of their disease and therapeutic regimen. This research was performed to find out types, prevalence and association between various predictors of potential drug-drug interactions (pDDIs) in the Department of Cardiology and to report common interactions. This study was performed in the hospitalized cardiac patients at Ayub Teaching Hospital, Abbottabad, Pakistan. Patient charts of 2342 patients were assessed for pDDIs using Micromedex® Drug Information. Logistic regression was applied to find predictors of pDDIs. The main outcome measure in the study was the association of the potential drug-drug interactions with various factors such as age, gender, polypharmacy, and hospital stay of the patients. We identified 53 interacting-combinations that were present in total 5109 pDDIs with median number of 02 pDDIs per patient. Overall, 91.6% patients had at least one pDDI; 86.3% were having at least one major pDDI, and 84.5% patients had at least one moderate pDDI. Among 5109 identified pDDIs, most were of moderate (55%) or major severity (45%); established (24.2%), theoretical (18.8%) or probable (57%) type of scientific evidence. Top 10 common pDDIs included 3 major and 7 moderate interactions. Results obtained by multivariate logistic regression revealed a significant association of the occurrence of pDDIs in patient with age of 60 years or more (p

    In diabetes mellitus dyslipidemia is one of the major risk factors for cardiovascular disease. In type 2 diabetes mellitus early detection and treatment of dyslipidemia can avoid risk for cardiovascular disorder. The present study was carried to determine the prevalence and pattern of hyperlipidemia in patients with hyperglycemia. The cross sectional study was done in different laboratories of Pakistan, the laboratories served patients referred from different government and private hospitals between July 2014 and June 2015. All known cases of diabetes mellitus were evaluated for their lipid profile. Totally 200 diabetic patients were included in the study in which 120 (60%) were males and 80 (40%) were females. Prevalence of dyslipidemia among diabetic males was 97.18% while for females 87.15%. Among dyslipidemic male the proportion with mixed dyslipidemic patients was 17.5%, combined two parameters dyslipidemia was 47.5% and isolated single parameter dyslipidemia was 35%. In females these proportions in mixed, combined two parameters and isolated single parameter were 16.25%, 51.25% and 32.5%, respectively. Majority of hyperglycemic patients were dyslipidemic. The most prevalent pattern among male was combined dyslipidemia with high triglycerides (TG) and low High Density Lipoprotein (HDL) and in female it was high Low Density Lipoprotein (LDL) and low HDL. The most prevalent lipid abnormality in our study was low HDL followed by high TG.

    Sains Malaysiana, 2017;46:917-924.
    The present study investigated the concentration of metals in commonly grown vegetables (Luffa acutangula L., Zea mays L., Solanum melongena L.) irrigated with waste water in District Bannu, Khyber Pakhtunkhwa, Pakistan. The pH (5.80) and electrical conductivity (13 dS/m) of waste water indicated the acidic nature that is not suitable for irrigation purposes. Soil and vegetables samples were analyzed for metals concentration through flame atomic absorption spectrometry (Varian FAAS-240). The findings showed that waste water irrigated soil was highly contaminated with Cd (4.62 mg/kg) which was above permissible limits set by European Union Standard (EU 2006, 2002). The concentrations of heavy metals such as Cr and Cd in vegetables were higher than the permissible limits set by World Health Organization/Food and Agriculture Organization U.S.A guidelines 2001. The health hazard quotient (HQ) of waste water irrigated vegetables was observed higher for Ni (0.699-0.1029 mg/kg), (0.0456-0.1040 mg/kg), (0.731-0.0994 mg/kg) in Luffa acutangula, Solanum melongena and Zea mays, respectively. The study concluded that the consumption of commonly grown vegetables in waste water zone of the study area may pose potential health threats in local population.

    Air heating by solar collectors is renewable technology providing hot air for different purposes. The present research
    emphasizes on analysis of energy, exergy and efficiency of a flat plate solar air heater. The analysis model was tested
    on five different air mass flow rates of 0.5 (Natural), 1.31, 2.11, 2.72 and 3.03 kgs-1 under three different tilt angles of
    25, 35 (Recommended) and 50o
    . The data was replicated three times making a total of 45 treatments. A two factorial
    completely randomized design was used to find if there is any significant difference among the treatments. The results
    showed that the solar collector gave better performance at air mass flow of 3.03 kgs-1 under tilt of 35o
    . At maximum
    air mass flow rate of 3.03 kgs-1and optimum tilt angle of 35o
    the maximum energetic efficiency of 51%, while minimum
    exergetic efficiency of 24% and maximum overall efficiency of 71% were recorded. It was concluded that to get maximum
    thermal efficiencies of 71% from flat plate solar collector used as an air heater must be operated at high air mass flow
    rates of 3.03 kgs-1under 35o
    tilt angle at Peshawar, Pakistan.

  20. Estimation of basic reproduction number for dengue fever in Lahore, Pakistan
    Noor Badshah, Hassan Shah, Muhammad Javid
    Sains Malaysiana, 2015;44:1423-1430.
    Dengue fever is a vector-borne viral disease which is now endemic in more than 100 countries affecting more than 2.5 billion people worldwide. In recent years, dengue fever has become a major threat to public health in Pakistan. In this paper, we derived an explicit formula for reproduction number R0 (the most important epidemiological parameter) and then used real data of dengue fever cases of different hospitals of Lahore (Pakistan) on R0. Conditions for local stability of equilibrium points are discussed. In the end, simulations are carried out for different situations.
