Background: the first reported case of COVID in all India was Thrissur, Kerala. Kerala one among states which had high recovery rate, low death rate and slow progression recognized internationally managing controlling COVID-19 pandemic. For efficient control transmission 19, mask wearing considered as primary popular measure. Wearing every time can cause discomfort prolonged usage lead to many health impacts. Mask be made comfortable convenient, if discomforts impacts are worked on future. Objective: study perceptions behavioral traits related general population Kerala, India. Methods: an online cross sectional conducted 291 adults aged 20 60 years with a validated questionnaire. Data analyzed Pearson’s Chi square Odds ratio. Results: majority participants were self-motivated, though 90 % mild discomforts, yet more than 80 inclined proper practice. Among participants, 77 washed reused masks, 49 changed their face touching behavior, 67 inspired by family friends mask. Older (greater 40 years) higher knowledge level use (98 %) masks outdoors (92,8 %), lesser preference for N95 double compared younger participants. Conclusion: reinforces hypothesis efficacy reducing pandemic spread. Community enhance planning implementation public programs

Effects of Face Masks on Physical Performance and Physiological Response during a Submaximal Bicycle Ergometer Test

International Journal of Environmental Research and Public Health, Год журнала: 2022, Номер 19(3), С. 1063 - 1063

Опубликована: Янв. 18, 2022

The ongoing COVID-19 pandemic requires wearing face masks in many areas of our daily life; hence, the potential side effects mask use are discussed. Therefore, present study explores whether a medical (MedMask) affects physical working capacity (PWC). Secondary, influence filtering facepiece with exhalation valve class 2 (FFP2exhal) and cotton fabric (community mask) on PWC was also investigated. Furthermore, corresponding physiological subjective responses when as well moderating role subjects' individual cardiorespiratory fitness sex were analyzed. Thirty-nine subjects (20 males, 19 females) different levels participated standardized submaximal bicycle ergometer protocol using either MedMask, FFP2exhal, community mask, or no (control) four days, randomized order.

The pharmaceutical industry is dangerous to health. Further proof with COVID-19

Surgical Neurology International, Год журнала: 2022, Номер 13, С. 475 - 475

Опубликована: Окт. 21, 2022

Background: The COVID-19 period highlights a huge problem that has been developing for decades, the control of science by industry. In 1950s, tobacco industry set example, which pharmaceutical followed. Since then, latter regularly condemned illegal marketing, misrepresentation experimental results, dissimulation information about dangers drugs, and considered as criminal. Therefore, this study was conducted to show knowledge is powerfully manipulated harmful corporations, whose goals are: 1/financial; 2/to suppress our ability make choices acquire global public health. Methods: Pharmaceutical techniques manipulating reporting were reviewed. Several sources official documents used: PubMed; National Institutes Health resources; companies; policy documents; national newspapers news agencies; books prominent professionals (scientific legal). A few studies have not published in peer-reviewed journals; however, they reputable scientists their respective fields. Results: beginning COVID-19, we can list following methods manipulation falsified clinical trials inaccessible data; fake or conflict-of-interest studies; concealment vaccines’ short-term side effects total lack long-term vaccination; doubtful composition vaccines; inadequate testing methods; governments international organizations under conflicts interest; bribed physicians; denigration renowned scientists; banning all alternative effective treatments; unscientific liberticidal social government use behavior modification engineering impose confinements, masks, vaccine acceptance; scientific censorship media. Conclusion: By supporting selecting only one while suppressing viewpoints, with obvious interest revealed study, media constantly disinform public. Consequently, unscientifically validated vaccination laws, originating from industry-controlled medical science, led adoption measures supposed protection but became serious threats health freedoms population.

Challenges and Adverse Effects of Wearing Face Masks in the COVID-19 Era

Challenges, Год журнала: 2022, Номер 13(2), С. 67 - 67

Опубликована: Дек. 19, 2022

Background: The use of face masks was a significant part the WHO COVID-19 preventive protocols. While their usage has been effective, lack adherence by individuals associated with discomfort and adverse side effects. This might facilitate unnecessary exposure to SARS-CoV-2 virus, thereby increasing incidence COVID-19. study assessed effects prolonged mask-wearing offers recommendations for present future pandemics. Methods: Adverse were evaluated from November 2021 February 2022 structured Google Forms online questionnaire. survey targeted regular occasional mask users around world. All responders anonymously completed survey, which included ten questions sub-section on continuous masks. information obtained analyzed using descriptive statistics, data presented in graphs. Results: Almost 60% (1243) 2136 participants indicated while Breathing difficulties pain ears cited as major causes discomfort, accounting 32% 22%, respectively, responses. Headaches reported 26.8% (572) respondents, 44.6% experiencing one within 1 h wearing mask. Nine hundred eight (908) respondents experienced nasal 412 various skin-related including excessive sweating mouth acne. Conclusions: provides baseline why there less includes headaches, skin irritation, ear pains, breathing difficulties, sore throat, dry eyes, increased mouth. As result, this may contribute an risk infection. lingers management its undesirable persists into future, it is vital that superior design, concentrating safety, comfort, tolerability, be developed.

Cationic lignin incorporated polyvinyl alcohol films for packaging applications

Industrial Crops and Products, Год журнала: 2024, Номер 221, С. 119217 - 119217

Опубликована: Авг. 2, 2024

Polyvinyl alcohol (PVA) films are used extensively in industry. However, their unacceptable air permeability and susceptibility to bacterial contamination problematic for some applications. This research investigates the incorporation of kraft lignin (KL) cationic (CKL) into PVA films. The results confirmed that KL enhanced UV blocking hydrophobicity while reducing porosity water absorption Despite improving blocking, hydrophilicity, capability film, oxygen were reduced, film became antibacterial when CKL was incorporated PVA. sustainable PVA/KL can potentially be packaging applications due improved hydrophobicity. In contrast, PVA/CKL medical performance reduced porosity.

Effects of wearing different facial masks on respiratory symptoms, oxygen saturation, and functional capacity during six-minute walk test in healthy subjects

Canadian Journal of Respiratory Therapy, Год журнала: 2022, Номер 58, С. 85 - 90

Опубликована: Июнь 21, 2022

During the current COVID-19 pandemic and increased air pollution levels, wearing a facial mask has been recommended. This study aimed to compare impact of different masks when performing submaximal functional activity (six-minute walk test; 6MWT) on respiratory symptoms, oxygen saturation, capacity. Twenty-nine subjects (10 men, 19 women; age 22 ± 1 yr.; FEV1/FVC 0.90 0.01) performed four rounds 6MWT (surgical (Medima SK, Thailand), handmade cloth, N95 (3M AuraTM 1870+, USA)) while not mask. Respiratory symptoms (dyspnea breathing effort), other physiological parameters were assessed before after each walking trial. Six-minute distances comparable between trials (P = 0.59). At end minute 6, significant difference groups was found dyspnea 0.02) effort < 0.001).

To Mask or Not to Mask—Evaluation of Cognitive Performance in Children Wearing Face Masks during School Lessons (MasKids)

Children, Год журнала: 2022, Номер 9(1), С. 95 - 95

Опубликована: Янв. 11, 2022

In the current SARS-CoV-2 pandemic, wearing a face mask is mandatory again during school lessons. There are no controlled studies in children to date indicating an effect on cognitive performance from masks. randomized trial, we analysed influence of masks pupils regular Pupils (n = 133, fifth seventh grade) were by alternating allocation into control (with masks, n 65) and intervention groups (without mask, 68). After two lessons with (control) without (intervention) class, all performed digital tests for regarding attention executive functions (switch, Corsi block-tapping, 2-back flanker task). Overall, there significant differences between both groups, vs. Wearing has can still be recommended
