ABSTRACT
PURPOSE: We sought to determine whether pollen triggers urological chronic pelvic pain syndrome flares. MATERIALS AND METHODS: We assessed flare status every 2 weeks for 1 year as part of the Multidisciplinary Approach to the Study of Chronic Pelvic Pain case-crossover analysis of flare triggers (NCT01098279). Flare symptoms, flare start date and exposures in the 3 days before a flare were queried for the first 3 flares and at 3 randomly selected nonflare times. These data were linked to daily pollen count by date and the first 3 digits of participants' zip codes. Pollen count in the 3 days before and day of a flare, as well as pollen rises past established thresholds, were compared to nonflare values by conditional logistic regression. Poisson regression was used to estimate flare rates in the 3 weeks following pollen rises past established thresholds in the full longitudinal study. Analyses were performed in all participants and separately in those who reported allergies or respiratory tract disorders. RESULTS: Although no associations were observed for daily pollen count and flare onset, positive associations were observed for pollen count rises past medium or higher thresholds in participants with allergies or respiratory tract disorders in the case-crossover (OR 1.31, 95% CI 1.04-1.66) and full longitudinal (RR 1.23, 95% CI 1.03-1.46) samples. CONCLUSIONS: We found some evidence to suggest that rising pollen count may trigger flares of urological chronic pelvic pain syndrome. If confirmed in future studies, these findings may help to inform flare pathophysiology, prevention and treatment, and control over the unpredictability of flares.

BACKGROUND: To investigate whether meteorological factors (temperature, barometric pressure, relative humidity, ultraviolet index [UVI], and seasons) trigger flares in male and female urologic chronic pelvic pain patients. METHODS: We assessed flare status every 2 weeks in our case-crossover study of flare triggers in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain 1-year longitudinal study. Flare symptoms, flare start date, and exposures in the 3 days preceding a flare or the date of questionnaire completion were assessed for the first three flares and at three randomly selected nonflare times. We linked these data to daily temperature, barometric pressure, relative humidity, and UVI values by participants' first 3 zip code digits. Values in the 3 days before and the day of a flare, as well as changes in these values, were compared to nonflare values by conditional logistic regression. Differences in flare rates by astronomical and growing seasons were investigated by Poisson regression in the full study population. RESULTS: A total of 574 flare and 792 nonflare assessments (290 participants) were included in the case-crossover analysis, and 966 flare and 5389 nonflare (409 participants) were included in the full study analysis. Overall, no statistically significant associations were observed for daily weather, no patterns of associations were observed for weather changes, and no differences in flare rates were observed by season. CONCLUSIONS: We found minimal evidence to suggest that weather triggers flares, although we cannot rule out the possibility that a small subset of patients is susceptible.

This study was planned to verify the resistance frequency of Ofloxacin (OFX) against Mycobacterium tuberculosis by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) technique and sequencing. Total 366 clinical samples of suspected TB patients were collected from various localities of central Punjab. All of them were found positive by ZN (Zeihl-Nelsen) staining method. Among them, 108 (29.5%) were found negative and 258 (70.5%) positive on PCR based study. The cases not responding to ATT were further characterized by proportion method and by PCR-RFLP to establish the drug resistance. Selected drug resistant case were further sequenced to confirm the results of amplified RFLP. The results showed that out of 118 drug resistant cases, 06 (5.08%), 03 (2.54%) were found resistant to OFX by drug susceptibility testing and PCR-RFLP respectively. The two strains were selected for sequencing procedure. The strain-79 showed point mutation at four points, at codon 70, 71, 76 and 78. The sequence of strain- 81 showed mutation at codon 95.PCR-RFLP is a useful molecular technique for the rapid detection of mutations and may be used to diagnose drug resistance but it should be confirmed by sequencing before starting 2(nd) and 3(rd) generation treatment because the restriction site is the cornerstone of PCR-RFLP and mutation may be occurring elsewhere.

Background: Quitting smoking is especially challenging for low-income smokers due to high stress, high smoking prevalence around them, and limited support for quitting. This study aimed to determine whether any of three interventions designed specifically for low-income smokers would be more effective than standard tobacco quitline services: a specialized quitline, the specialized quitline with social needs navigation, or the standard quitline with social needs navigation. Methods: Using a randomized 2 × 2 factorial design, low-income daily cigarette smokers (n = 1944) in Missouri, USA who called a helpline seeking assistance with food, rent or other social needs were assigned to receive Standard Quitline alone (n = 485), Standard Quitline + Social Needs Navigation (n = 484), Specialized Quitline alone (n = 485), or Specialized Quitline + Social Needs Navigation (n = 490). The target sample size was 2000, 500 per group. The main outcome was 7-day self-reported point prevalence abstinence at 6-month follow-up. Multiple imputation was used to impute outcomes for those missing data at 6-month follow-up. Binary logistic regression analyses were used to assess differences between study groups. Findings: Participants were recruited from June 2017 to November 2020; most were African American (1111 [58%]) or White (666 [35%]), female (1396 [72%]), and reported <$10,000 (957 [51%]) or <$20,000 (1529 [82%]) annual pre-tax household income. At 6-month follow-up (58% retention), 101 participants in the Standard Quitline group reported 7-day point prevalence abstinence (20.8% of those assigned at baseline, 38.1% after imputation). Quit rates in the Specialized Quitline (90 quitters, 18.6%, 38.1%) and Specialized Quitline + Social Needs Navigation (103 quitters, 21.0%, 39.8%) were not different from the Standard Quitline. Quit rates for Standard Quitline + Social Needs Navigation (74 quitters, 15.3%, 30.1%) were significantly lower than Standard Quitline (OR = 0.70, 95% CI = 0.50-0.98). Interpretation: A specialized version of a state tobacco quitline was no more effective than standard quitline services in helping low-income smokers quit. Adding social needs navigation to a standard quitline decreased its effectiveness. Trial registration: ClinicalTrials.gov Identifier: NCT03194958. Funding: National Cancer Institute: R01CA201429.
ABSTRACT
Background: The analgesic drugs are the main cause of gastric ulcer. The objective of this study was to determine the gastroprotective ability of flavonoid, 6-aminoflavone in a rat pyloric ligation model of aspirin associated gastro-ulcerogenesis. Methods: A laboratory based experimental study was conducted in the animal house and research laboratory at Khyber Medical College, Peshawar from July to November 2019. A total of 42 adult male Spargue-Dawely rats were divided into seven groups. Flavonoid, 6-aminoflavone was administered orally in doses of 10, 25 and 100 mg/kg with misoprostol, as standard at 50 µg/kg orally for 4 days. On the last day aspirin was given orally at 200 mg/kg and the pyloric ligation surgery was performed. After 4 hours all animals were killed by cervical dislocation. The gastric tissues were collected for histomorphological study. The obtained data were expressed as mean±SEM. Analysis was carried out by using ANOVA. p value Ë0.05 was considered significant. Results: The animals treated with the different doses of 6-aminoflavone showed a marked protective effect in the histological observations. The 10 mg/kg dose had a mild protective effect as occasional ulcerative changes were observed. However, doses of 25 and 100 mg/kg significantly caused the reduction in the ulcer score. These effects produced were equipotent to the gastroprotective effectiveness inherent in the misoprostol. . Conclusion: These findings conclude that 6-aminoflavone as like other flavonoids has a significant gastroprotective propensity with significant effect produced at doses of 25 and 100 mg/kg and can be used as a part of therapy management for the treatment of gastrointestinal disease particularly ulcerative condition.

BACKGROUND: Low-income Americans smoke cigarettes at higher rates and quit less than other groups. METHODS: To increase their engagement in and success using evidence-based cessation methods, we tested two interventions using a 2x2 randomized factorial design: (1) telephone navigation to reduce financial strain and address social needs such as food, rent and utility payment; and (2) a specialized tobacco quitline designed for low-income smokers. From June 2017 to November 2020, we enrolled 1,944 low-income smokers in Missouri, USA, recruited through the Missouri 2-1-1 helpline, into the trial. This paper describes recruitment, key characteristics and life circumstances of this high-risk population. RESULTS: After eligibility screening, 1,944 participants completed baseline and were randomized. Participants were racially diverse (58% African American), poor (51% < $10,000 annual pre-tax household income) and many reported less than high school education (30%). They reported a mean of 2.5 unmet social needs, especially childcare and paying bills, had high rates of stress, depressive symptoms and sleep problems, and most were in fair or poor health. There were few differences between these variables, and no differences between tobacco use and cessation variables, across the four study groups and between participants recruited pre and during the COVID-19 pandemic. CONCLUSIONS: Trial recruitment through the 2-1-1 helpline is feasible for reaching a population of low-income smokers. Low-income smokers face myriad daily challenges beyond quitting smoking. Cessation interventions need to account for and address these life circumstances. TRIAL REGISTRATION: Clinicaltrials.gov NCT03194958.
ABSTRACT
Health care providers are increasingly screening low-income patients for social needs and making referrals to social services agencies to assist in resolving them. A major assumption of this approach is that local social services providers have the capacity and resources to help. To explore this assumption, we examined 711,613 requests related to fifty different social needs received from callers to 211 helplines in seven states during 2018. Our analyses focused on the proportion of requests for which referrals could not be made because of low capacity in the social services system. We examined the extent to which the capacity of this system varied by type of social need, ZIP code, and time of year, and we classified social needs in a new typology based on prevalence and system capacity. It is clear that health care's current screening and referral approach is appropriate for some social needs but not others.

Based on progress for the green synthesis of nanoparticle (NPs), the mushrooms have also been utilized extensively for the biogenic synthesis of NPs. In recent years, silver NPs have been fabricated using mushrooms. The antimicrobial drugs are efficient to control the infectious diseases, but due to widespread of drugs, microbes became resistant to drugs, which demands develop of new bioactive agents. The silver NPs have been recognized as efficient broad spectrum antimicrobial agents, which have been fabricated using polysaccharides from mushrooms as reducing and capping agent. This review focused on the comprehensive study that deals silver NPs polysaccharides from Pleurotus mushroom, their synthesis mechanism, action mechanism of silver NPs and their characterization using advanced techniques i.e., ultraviolet-visible (UV-Vis), dynamic light scattering, Fourier transformation infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM) and XRD. The Pleurotus mushroom showed promising efficiency for the biogenic synthesis of polysaccharidessilver NPS and as-prepared NPs showed excellent antimicrobial activity.

BACKGROUND: Diabetes Mellitus (DM) is an advanced and chronic endocrine disorder characterized by an insufficiency of insulin secretion from pancreatic ß-cells and liver, adipose tissues, and skeletal muscles. OBJECTIVE: The main objective of this study is to understand the mechanism and genes which are responsible for the prevalence of diabetes. The study also covers various types of diabetic complications with special reference to insulin role and defects. METHODS: The scientific literature and patents were reviewed and analyzed based on their suitability and relevance to the theme of the study. The scientific literature was covered from the authentic databases such as Elsevier, Springer, and Bentham Science. The patents were reviewed from http://www.freepatentsonline.com. RESULTS: Glucokinase (ATP: D-glucose-6-phosphotransferase; GCK), initiates glycolysis and acts as a glucose sensor and metabolic signal producer in liver and pancreas. PCR-sequencing showed qualitative differences in diabetic patients in comparison to healthy subjects. Glucokinase is the most important component in glucose detection of pancreatic islet beta cells in diabetes because glucokinase mutations can be one of the most common single gene disorders described. It is known that a genetic variation of a human glucokinase gene, including a point mutation, causes MODY, the concentration of plasma glucose increased and it is supposed to be the cause of diabetes of the present study subjects. Owing to hyperglycemia and individual components of the insulin resistance (metabolic) syndrome, people with Type II DM are prone to the high threat for microvascular complications (including nephropathy, retinopathy, and neuropathy) and macrovascular complications (such as Ischemic Heart Disease). There were also significant differences (P < 0.0001) in glycation levels (0.90, 0.4838mole/mole), random blood sugar (348.8, 105.8mg/dL), cholesterol levels (235.3, 161.8mg/dL), low density lipoprotein in diabetic subjects (155.3, 28.46mg/dL) and in healthy donors. GCK gene mutations were found in 70% of the patients while 30% are non-mutated. CONCLUSION: In conclusion, lipids, glucose, and protein play an essential role in the initiation of AGE's or diabetic complications (Micro and Macrovascular Complications). The importance of the clinical results should also be recognized in the genetic analysis of heterogeneous disorders as NIDDM/ Type II DM.

Drosophila melanogaster being used as model organism is considered as pest of homes, restaurants, and fruit markets. The damaged fruits are also reported to serve as a carrier for various diseases. The current study was designed to evaluate the toxicity of petroleum extract of some weed plants, namely, Euphorbia prostrata, Parthenium hysterophorus, Fumaria indica, Chenopodium murale, and Azadirachta indica, against D. melanogaster. Mortality at 10, 20, and 30% concentrations after 24 and 48 hours was found comparatively low. E. prostrata caused high mortality (51.64%) at 30% concentration and was found more toxic (LC50 27.76; P value 0.00) after 72 hours. A. indica showed high LC50 value (P value 0.15) compared to other weed plants. The combination of E. prostrata and Bti showed highest mortality (100%; LC50 12.49; P value 0.00) after 72 hours. Similarly, the same combination caused maximum reduction in the activity of AChE, AcP, AkP, α-Carboxyl, and ß-Carboxyl enzymes. Phytochemical analysis showed the presence of flavonoids, saponins, tannins, steroids, cardiac glycosides, alkaloids, anthraquinones, and terpenoids. FTIR analysis of E. prostrata showed the presence of phenolic compounds. It is suggested that further studies are needed in order to incorporate weed plant extracts in combination with Bti for the management of fruit flies.
ABSTRACT
The study was carried out to determine, by PCR-RFLP, the magnitude of drug resistance in Mycobacterium tuberculosis The study was carried out on 221 random sputum samples collected from patients and 120 suspected cases of drug resistance. Genetic variation in drug-resistant strains was evaluated through PCR-RFLP for isoniazid, ethambutol, streptomycin, and ofloxacin. Out of 341 patients, 91.5% were confirmed as M. tuberculosis complex infected on the basis of PCR. The random samples revealed resistance in 8.2% cases, while 73.3% of those with suspected drug resistance were found resistant. Among drug-resistant isolates, 56.1% were resistant to a single drug, 33.3% to two drugs, and 10.6% to more than two drugs. Ofloxacin resistance was observed along with isoniazid, ethambutol, and streptomycin in 6.5% cases. Resistance to isoniazid was observed in 61% cases, to ethambutol in 50.4%, and to streptomycin in 43.1% cases. It was concluded that PCR-RFLP is a useful molecular technique for the rapid detection of mutations in drug-resistant tuberculosis patients and may be used to diagnose drug resistance at the earliest.
