Tackling the Antimicrobial Resistance "Pandemic" with Machine Learning Tools: A Summary of Available Evidence.

Antimicrobial resistance is recognised as one of the top threats healthcare is bound to face in the future. There have been various attempts to preserve the efficacy of existing antimicrobials, develop new and efficient antimicrobials, manage infections with multi-drug resistant strains, and improve patient outcomes, resulting in a growing mass of routinely available data, including electronic health records and microbiological information that can be employed to develop individualised antimicrobial stewardship. Machine learning methods have been developed to predict antimicrobial resistance from whole-genome sequencing data, forecast medication susceptibility, recognise epidemic patterns for surveillance purposes, or propose new antibacterial treatments and accelerate scientific discovery. Unfortunately, there is an evident gap between the number of machine learning applications in science and the effective implementation of these systems. This narrative review highlights some of the outstanding opportunities that machine learning offers when applied in research related to antimicrobial resistance. In the future, machine learning tools may prove to be superbugs' kryptonite. This review aims to provide an overview of available publications to aid researchers that are looking to expand their work with new approaches and to acquaint them with the current application of machine learning techniques in this field.

Evaluation of Reporting Quality of Glaucoma Randomized Controlled Trial Abstracts: Current Status and Future Perspectives.

The aim of this study was to explore adherence to the Consolidated Standards of Reporting Trials (CONSORT) reporting standards in abstracts of randomized controlled trials on glaucoma. A cross-sectional observational study was conducted on the aforementioned abstracts, indexed in MEDLINE/PubMed between the years 2017 and 2021. In total, 302 abstracts met the inclusion criteria and were further analyzed. The median score of CONSORT-A items was 8 (interquartile range, 7-10) out of 17 (47.0%). Most analyzed studies were conducted in a single center (80.5%) and the abstracts were predominantly structured (95.0%). Only 20.5% of the abstracts adequately described the trial design, while randomization and funding were described by 6.0% of the abstracts. Higher overall scores were associated with structured abstracts, a multicenter setting, statistically significant results, funding by industry, a higher number of participants, and having been published in journals with impact factors above four (p < 0.001, respectively). The results of this study indicate a suboptimal adherence to CONSORT-A reporting standards, especially in particular items such as randomization and funding. Since these factors could contribute to the overall quality of the trials and further translation of trial results into clinical practice, an improvement in glaucoma research reporting transparency is needed.

Knowledge and Attitudes towards Epilepsy of Croatian General Student Population and Biomedical Students: A Cross-Sectional Study.

Epilepsy causes a significant burden to patients as it is linked with various somatic and psychiatric comorbidities, social issues, impaired quality of life, and increased mortality. Improving the population's knowledge and attitudes about epilepsy patients could be beneficial as it could raise social awareness and lead to more social support for patients. For those reasons, a survey-based cross-sectional study was conducted to determine Croatian students' knowledge and attitudes toward epilepsy. A previously developed survey questionnaire was adapted for the Croatian setting and distributed online to the students (n = 544). Croatian students generally had positive attitudes towards people with epilepsy (median score 28.0, interquartile range 29.0-26.0, with the minimum possible score being 0.0 and the maximum 30.0), with the female gender (B (male) = 0.664 (95% CI -1.158, -0.170), p = 0.009), biomedical education (B (other) = -0.442, (95% CI -0.823, -0.061), p = 0.023), and personal experience in the form of witnessing the seizure (B = 0.519 (95% CI 0,098, 0.940), p = 0.016) as predictors of more favorable attitudes. Overall knowledge was satisfactory concerning most items, with the exception of first aid measures and risk factors. Educational intervention targeting bio-medical students and other students who might, in their future professional lives, be responsible for people suffering from epilepsy is needed to improve the gaps in their knowledge.

Young Women's Attitudes and Behaviors in Treatment and Prevention of UTIs: Are Biomedical Students at an Advantage?

We wanted to investigate whether students who study within biomedical fields (i.e., medicine, pharmacy science) differ from those whose studies are not connected to the biomedical field in terms of their attitudes and behaviors related to urinary tract infections (UTIs). This was a cross-sectional survey-based study conducted among 392 female students, of whom 243 attended a biomedical school and 149 (38.0%) attended a non-biomedical school, using a previously published tool. The survey was distributed as an online link via student representatives at different faculties. Only 22 (5.6%) of women felt that they could not recognize a UTI. A greater proportion of biomedical students wiped front to back, while significantly more non-biomedical students chose cotton underwear and avoided daily sanitary pads compared to biomedical students. As many as 215 (54.8%) women stated that they used cranberry preparations. Biomedical students showed greater awareness about possible resistance to repeated treatment (p = 0.002) and greater knowledge of possible interactions of antibiotics (p < 0.001). This study reveals that young women are confident in recognizing an UTIs, are open to alternative treatments, and would consider UTI management in a pharmacy setting. However, it reveals that there might be gaps in their knowledge regarding antibiotic resistance risks, possible interactions, and efficacy of available preparations, as participants from the group of biomedical students showed greater knowledge and different behaviors.

Attitudes of Community Pharmacy Service Users towards Vaccination Programs in Pharmacy: A Cross-Sectional Survey-Based Study in Croatia.

BACKGROUND: The aim of this study was to explore community pharmacy service users' attitudes and opinions towards vaccination programs in pharmacy conducted by a doctor of medicine or a pharmacist. METHODS: The questionnaire used in this study comprised 40 items about demographics, sources of information, attitudes about vaccination, attitudes about vaccination in community pharmacies, and willingness to pay for such a service. RESULTS: A total of 385 people participated in this study. Injection was the preferred route of administration of vaccine for more than half of study participants (50.6%). Univariate analysis showed that those who had a healthcare worker as a family member and those familiar with the HPV vaccine had better attitudes; however, those results were no longer significant after factoring in other variables in multivariate analysis. More than half (59.2%) of the study population would consider vaccination service in community pharmacies only if it were free or covered by the national health insurance. CONCLUSIONS: More than half of the participants believed that providing vaccination services in community pharmacies would result in greater vaccination rates for seasonal illnesses. However, around half would prefer that it were conducted exclusively by a physician. Less than 10% of the study participants would pay out of their pocket for such a service.

Adverse drug reaction reporting via mobile applications: A narrative review.

INTRODUCTION: Pharmacovigilance importance has increased in the last few decades and it has led to rise in awareness of adverse drug reaction reporting by both patients and health care professionals. Despite this, research shows reporting practice of health care professionals remains inadequate. Several educational and promotional activities were established in order to improve observed underreporting including the introduction of mobile applications that can be used to report adverse drug reactions. OBJECTIVES: We aimed to review literature on adverse drug reaction reporting applications and whether their introduction improved reporting practice in patients and health care professionals. RESULTS: In this review, we have described several mobile application implementations in different countries. Moreover, we have illustrated some of the applications for particular patients, e.g. patients with multiple sclerosis. CONCLUSION: All of the included studies showed positive association between application use and ADR reporting. However, there is a great need for future high quality studies to confirm impact of mobile application on ADR reporting.

Registered Drug Packs of Antimicrobials and Treatment Guidelines for Prostatitis: Are They in Accordance?

The aim of this study was to analyze if registered drug packs of antibiotics are in accordance with national guidelines for prostatitis treatment regard to the amount of drug units.; Methods: Croatian, UK (NICE), Australian, Spanish and Slovenian national guidelines were analyzed in this study. Results: Comparing treatment guidelines with registered drug packs resulted in perfect accordance only for drug packs registered in the UK with the NICE guidelines, where even split-pack dispensing is possible. Interestingly, when comparing drug packs registered in the UK with treatment proposed in the national guidelines of Croatia, Italy, Spain, Australia, USA and Slovenia, they matched almost perfectly. In other investigated countries, registered drug packs' national guidelines' analysis showed mismatch in 25-100% of recommendations (Italy and Slovenia, respectively). Conclusions: Mismatch between registered drug packs that are dispensed to patients and treatment guidelines may result in excess units of antimicrobials that may be misused by the patient in the future, or excess antimicrobials may become unnecessary waste, further promoting antimicrobial resistance. Greater accordance of registered drug packs of antimicrobials with treatment guidelines may lower rates of antimicrobials misuse.

Comparison of the Impact of Insulin Degludec U100 and Insulin Glargine U300 on Glycemic Variability and Oxidative Stress in Insulin-Naive Patients With Type 2 Diabetes Mellitus: Pilot Study for a Randomized Trial.

BACKGROUND: There is an ongoing discussion about possible differences between insulin degludec (IDeg-100) and glargine U300 (IGlar-300). There is little data and head-to-head comparison of IDeg-100 and IGlar-300 regarding their simultaneous impact on glycemic variability and oxidative stress in patients with type 2 diabetes mellitus (T2DM). OBJECTIVE: In our randomized, open-label, crossover study, we compared the impact of IDeg-100 and IGlar-300 on glycemic variability and oxidative stress in insulin-naive patients with T2DM. METHODS: We recruited a total of 25 adult patients with T2DM (7 females) whose diabetes was uncontrolled (HbA1c ≥7.5%) on two or more oral glucose-lowering drugs; a total of 22 completed the study. Mean age was 57.3 (SD 6.99) years and duration of diabetes was 9.94 (SD 5.01) years. After the washout period, they were randomized alternately to first receive either IDeg-100 or IGlar-300 along with metformin. Each insulin was administered for 12 weeks and then switched. At the beginning and end of each phase, biochemical and oxidative stress parameters were analyzed. On 3 consecutive days prior to each control point, patients performed a 7-point self-monitoring of blood glucose profile. Oxidative stress was assessed by measuring thiol groups and hydroperoxides (determination of reactive oxygen metabolites test) in serum. RESULTS: IGlar-300 reduced mean glucose by 0.02-0.13 mmol/L, and IDeg-100 reduced glucose by 0.10-0.16 mmol/L, with no significant difference. The reduction of the coefficient of glucose variation also did not show a statistically significant difference. IGlar-300 increased thiols by 0.08 µmol/L and IDeg-100 increased thiols by 0.15 µmol/L, with no significant difference (P=.07) between them. IGlar-300 reduced hydroperoxides by 0.040 CARR U and IDeg-100 increased hydroperoxides by 0.034 CARR U, but the difference was not significant (P=.12). CONCLUSIONS: The results of our study do not show a significant difference regarding glycemic variability between patients receiving either insulin IDeg-100 or IGlar-300, although IGlar-300 showed greater dispersion of data. No significant difference in oxidative stress was observed. In a larger study, doses of insulins should be higher to achieve significant impact on glycemic parameters and consequently on glycemic variability and oxidative stress.

Helicobacter pylori Infection in Croatian Population: Knowledge, Attitudes and Factors Influencing Incidence and Recovery.

Basic and clinical knowledge about Helicobacter pylori infections has been improved in the past. However, the translation of this knowledge into public health intervention has remained poor. A survey based cross-sectional study was performed to assess the factors regarding the H. pylori infection in the general population. The survey was conducted using a previously developed questionnaire, adapted for the population in Croatia. Respondents (N = 1131) had a good knowledge score with a median of 4 out of 5 correct answers (interquartile range: 2-4). Senior participants had a lower frequency of high knowledge answers about H. pylori (43.1%) compared to younger (56.1%) and middle-aged participants (51.5%, p = 0.014). Rural participants had a higher frequency of low knowledge answers compared to urban and suburban ones (21.7% vs. 9.5% and 9.4%, p = 0.011). Only 315 participants (27.9%) were screened for the H. pylori infection, despite high support for the screening programs among the untested (74.7%) and tested (85.7%). Habits of smoking (p = 0.036) and coffee drinking (p = 0.008) were associated with more symptoms after eradication therapy. Further education is needed for the groups at risk for H. pylori infection, especially to raise the awareness of the importance of screening programs. More research is warranted to assess the effects of dietary changes on therapy outcomes.

Did an introduction of CONSORT for abstracts guidelines improve reporting quality of randomised controlled trials' abstracts on Helicobacter pylori infection? Observational study.

OBJECTIVE: To determine abstracts' adherence to the Consolidated Standards of Reporting Trials for Abstracts (CONSORT-A) statement and to explore the factors associated with reporting quality. DESIGN: An observational study. SETTING: Abstracts of randomised controlled trials published between 2010 and 2019, found searching the MEDLINE database. PARTICIPANTS: A total of 451 abstracts of the clinical trials on Helicobacter pylori infections were included. PRIMARY AND SECONDARY OUTCOME MEASURES: Abstracts' reporting quality was determined by assessing their adherence to 17-item CONSORT-A checklist, with overall score being calculated as the sum of items that were adequately reported for each abstract. Additional factors that might influence the reporting quality of the abstracts were analysed, with univariate and multivariate linear regression used to determine how those factors influenced the overall reporting quality. RESULTS: Included abstracts had an overall median quality score of 8/17 (IQR 7-9). Large proportions of abstracts adequately reported interventions, participants, objectives, numbers randomised and conclusions (97.1, 99.3, 89.1. 94.7 and 98.4% of abstracts, respectively). Trial design, randomisation, blinding and funding were severely under-reported with only 8.0, 2.7, 11.0 and 2.0% of abstracts reporting each item. Overall quality scores for H. pylori abstracts were higher in association with CONSORT-A endorsement (B=5.698; 95% CI 1.781 to 9.615), pharmacological interventions (B=4.063; 95% CI 0.224 to 7.902), multicentre settings (B=5.057; 95% CI 2.370 to 7.743), higher numbers of participants (B=3.607; 95% CI 1.272 to 5.942), hospital settings (B=4.827; 95% CI 1.753 to 7.901) and longer abstracts (B=3.878; 95% CI 0.787 to 6.969 for abstracts with 251-300 words and B=7.404; 95% CI 3.930 to 10.878 for abstracts with more than 300 words). CONCLUSIONS: The overall reporting quality of abstracts was inadequate. The endorsement of CONSORT-A guidelines by more journals might improve the standards of reporting.

Teaching Pharmacovigilance to Healthcare Students: Identifying Gaps and Opportunities for Improvement.

The literature indicates that the limited pharmacovigilance knowledge demonstrated by healthcare professionals is the main reason for the underreporting of adverse drug reactions. Therefore, the main objective of this study was to investigate pharmacy, dental and medical students' knowledge and attitudes to pharmacovigilance and pharmacovigilance education. The cross-sectional questionnaire study was conducted at the University of Split School of Medicine in November 2020. In total, 350 students participated in the study. The results have shown that pharmacy students showed a significantly higher knowledge score compared to dental and medical students (P < 0.001). In total 92.2% of pharmacy, 21.8% of dental and 70.8% of medical students had knowledge of patients' involvement in adverse drug reactions, reporting (P < 0.001). Interestingly, only 44.3% of all students knew that adverse drug reactions could be reported using a mobile application. Moreover, significantly more pharmacy students (74.4%) were aware of the adverse drug reactions monitoring center in Croatia, with 47.5% of dental and 39.2% of medical students correctly identifying it (P < 0.001). The results showed that most students felt that pharmacovigilance was not adequately covered in curricula; therefore, there is a great need to increase the knowledge and awareness of pharmacovigilance among students aspiring to become future healthcare professionals, and improve their reporting practice in clinical future.

Implications of COVID-19 Pandemic on the Emergence of Antimicrobial Resistance: Adjusting the Response to Future Outbreaks.

The net effect of the coronavirus disease 2019 (COVID-19) pandemic and the response to it on the emergence of antimicrobial resistance is yet unknown. Positive impacts on the spread of multiresistant pathogens and infections in general may be observed with the implementation of general preventative measures for the spread of infectious disease such as social distancing, reduced travel and increased personal hygiene. This pandemic has accelerated the development of novel technologies, such as mRNA vaccines, that may be used to fight other diseases. These should be capitalized upon to manage the ongoing antimicrobial resistance pandemic in the background. However, it is likely that the COVID-19 pandemic is fueling the emergence of antimicrobial resistance due to high rates of inappropriate antimicrobial prescribing, the high use of biocides and the interruption of treatment for other conditions. Clinical uncertainty driven by the lack of effective diagnostics and practice of telemedicine may have driven the inappropriate use of antimicrobials. As pathogens know no borders, increased focus is needed for infectious diseases still threatening low- and middle-income countries such as tuberculosis. Stewardship measures for future outbreaks should stress the importance of social distancing and hand washing but discourage the overuse of disinfectants and antimicrobials that are not proven effective.

Seasonal variations in nutritional status and oxidative stress in patients on hemodialysis: Are they related?

OBJECTIVE: Seasonal variations in body composition and parameters that reflect nutritional status are well established in patients on hemodialysis (HD). However, to our knowledge, no study has assessed the changes in oxidative stress (OS). The aims of this study were to assess seasonal variations in OS, body composition, and other nutritional parameters. METHODS: Seasonal variations in fat tissue mass (FTM), fat tissue index (FTI), adipose tissue mass (ATM), lean tissue mass (LTM), lean tissue index (LTI), body cell mass (BCM), overhydration (OH) volume, and OS (blood levels of derivatives of reactive oxygen metabolites [d-ROMs], thiobarbituric reactive substances, plasma protein reduced thiol content [THIOLS], and ferric reducing ability of plasma) were assessed in 45 patients on HD, 70 y of age (60.5-76.5 y). RESULTS: FTM (P < 0.001), FTI (P < 0.001), and ATM (P < 0.001) significantly increased, whereas LTI (P < 0.001), LTM (P < 0.001), BCM (P < 0.001), and OH volume (P = 0.004) significantly decreased over the season. Additionally, significant seasonal variations in the levels of d-ROMs (P = 0.02) and THIOLS (P = 0.02) were found. Levels of d-ROMs were found to be a significant predictor of LTM and BCM (ß = -0.57; 95% confidence interval [CI], -1.08 to -0.06; P = 0.03; ß = -0.04; 95% CI, -0.075 to -0.006; P = 0.02). Furthermore, hip circumference was found to be the most significant predictor of the level of d-ROMs (ß = 2.66; 95% CI; 0.28-5.04; P = 0.03) and waist-to-height ratio (ß = 251; 95% CI, 16.6-477.2; P = 0.03) and serum prealbumin levels of THIOLS (ß = 263; 95% CI, 6.8-521.1; P = 0.04). CONCLUSION: These results suggest seasonal variations in OS in patients on HD and a possible interaction between OS and nutritional status in these patients.

Community pharmacists' use, perception and knowledge on dietary supplements: a cross sectional study.

BACKGROUND: Pharmacists are commonly tasked with recommending the appropriate dietary supplement and advising the patients of their correct and safe use. Previous research, conducted on pharmacy students, showed that they did not always use the evidence based sources of information, with personal use identified as a significant predictor influencing the decision to recommend a supplement. OBJECTIVES: To compare use, perceptions and knowledge of dietary supplements of pharmacists with different years of work experience and to explore factors that could influence their recommendation of supplements. METHODS: A questionnaire based cross-sectional study was conducted on Croatian community pharmacists in September 2017. The questionnaire explored pharmacists' demographic characteristics, use, perceptions and knowledge of dietary supplements. Pharmacists (N=102) were divided in two groups based on their work experience: P0 (<10 years) and P1 (≥10 years). RESULTS: All included pharmacists had high knowledge scores without differences between groups (P0=10, IQR 9-12 vs P1=11, IQR 9-12, expressed as median and interquartile range (IQR), p=0.275). Less experienced pharmacists perceived there was less research conducted on the dietary supplements compared to their more experienced counterparts (P0=1, IQR 1-2 vs P1=2, IQR 2-3, expressed as median and interquartile range, p<0.001). Groups differed in sources used when choosing the appropriate supplement with P0 using higher quality sources such as systematic reviews in comparison to P1 (32.1% vs 8.7%, p=0.004). Pharmacists' decision to recommend a dietary supplement was influenced by their personal use (odds ratio 0.216, 95%CI 0.068:0.689, p=0.01) and work experience (odds ratio 0.154, 95%CI 0.045:0.530, p=0.003). CONCLUSIONS: Pharmacists did not use the high quality sources when recommending dietary supplements and their decision to recommend the supplement was not based on objective evaluation of evidence. Further education about the practice of evidence-based pharmacy is necessary, with special emphasis on senior pharmacists who might have missed that aspect during their formal education.

Are We Making the Most of Community Pharmacies? Implementation of Antimicrobial Stewardship Measures in Community Pharmacies: A Narrative Review.

Community pharmacists recognize the need to implement antimicrobial stewardship activities in community pharmacies. They are in a unique position to provide triage for common primary care indications and to lower the burden of patients at general practitioners' offices. However, research shows that, in some areas, dispensing of antimicrobials without valid prescription is still highly prevalent. Regardless of training, every community pharmacist can give his contribution to antimicrobial stewardship. One of the basic elements should be antimicrobial dispensing according to regulations, either prescription only, or according to guidelines where pharmacists have prescribing authority. Patient consultation supported with educational materials, such as leaflets, may reduce patients' expectations to receive antibiotics for self-limiting infections and reduce pressure on general practitioners to prescribe antibiotics on patients' demand. Treatment optimization may be achieved in collaboration with the prescribing general practitioners or by providing feedback. At last, pharmacists provided with additional training may be encouraged to provide consultation services to long-term care facilities, to introduce point-of-care testing for infectious diseases in their pharmacies or prescribe antimicrobials for uncomplicated infections. These services are welcomed by patients and communities. Expanding pharmacy services and pharmacists' prescribing autonomy have shown a positive impact by reducing antibiotics consumption, thus ensuring better compliance with treatment guidelines.

Adherence to Maastricht V/Florence consensus report for the management of Helicobacter pylori infection among primary care physicians and medical students in Croatia: A cross-sectional study.

BACKGROUND: Helicobacter pylori (H pylori) eradication is becoming increasingly difficult. The aim of our study was to determine the knowledge of current guidelines and attitude in the diagnosis and treatment of H pylori infection in primary care physicians (PCPs) and medical students in Croatia. MATERIALS AND METHODS: A study was conducted among PCPs and medical students to evaluate adherence to Maastricht V consensus guidelines. Questionnaire was distributed by e-mail to 2338 PCPs offices in Croatia and to the medical students from the University of Split School of Medicine. Responses were collected electronically from June 22 to August 22, 2020. RESULTS: Two hundred forty-nine PCPs and 169 medical students were included in the study. Bismuth or non-bismuth-based quadruple therapy as first-line treatment for H pylori was the choice of 4.8% of PCPs and 13% of students, while 66.3% PCPs and 79.9% students would choose clarithromycin-based triple therapy. Bismuth-based quadruple therapy was the most preferred second line of treatment for 45.4% of PCPs and 34.9% of students. Only 2.8% PCPs and 7.1% of students would correctly recommend first and second line of treatment for H. pylori infection. A larger proportion of students than PCPs would prefer C13-urea breath test (50.3% vs 6.4%). Only 59.0% PCPs would treat for H pylori in all patients including the asymptomatic ones. Students more frequently recognized the link between H pylori and gastric cancer compared with PCPs (92.9% vs 73.5%). CONCLUSIONS: Primary care physicians and medical students' knowledge of H pylori guidelines are insufficient in Croatia and ask for additional training.

Antimicrobial Resistance: Physicians' and Pharmacists' Perspective.

Aims: The aim of this study was to evaluate pharmacists' and physicians' attitudes and knowledge about antimicrobial treatment and resistance and based on the results to identify possible gaps and suggest opportunities for collaboration between the two professions. Methods: The physician's questionnaire consisted of 47 items and the pharmacists' questionnaire consisted of 50 items. Participants were asked to identify situations in which they were more likely to prescribe/dispense an antimicrobial without a firm indication, to identify the greatest contributors to antimicrobial resistance (AMR) among health care workers, to rate statements related to AMR, how frequently they used different sources of information and to rate the possible causes of AMR. Furthermore, preparedness for specific actions in practice was self-rated and knowledge was evaluated. The questionnaires were anonymous and participation in the study was voluntary. Results: This research included 180 community pharmacists and 181 physicians. As many as 76 (42.0%) physicians stated they would prescribe an antimicrobial when unsure whether the infection was of viral or bacterial etiology. More than half of the participants considered family medicine doctors the greatest contributors to AMR (N = 216, 59.8%), followed by patients (N = 175, 48.5%). In questions focusing on knowledge, physicians scored significantly higher compared with pharmacists (4.06 ± 1.01 vs. 3.71 ± 1.08, p = 0.001). Conclusion: This research revealed practices among pharmacists and physicians that should be improved and it highlighted gaps in knowledge by both professions. More attention should be given to patient consultation when dispensing and prescribing an antimicrobial as this may reduce their contribution to AMR.

Comparison of mechanical, chemical and physical human models of in vivo skin damage: Randomized controlled trial.

INTRODUCTION: Human in vivo models of skin damage were often used in research of cutaneous disorders. The most commonly used models were tape-stripping as mechanical, sodium lauryl sulphate-induced irritation as chemical and ultraviolet radiation as physical damage model. In regard to differences between models, they were expected to have different responses to damage and recovery, with unique skin parameters' changes over time. OBJECTIVE: The aim was to compare skin parameters in three different skin damage models on the same anatomical location, with and without topical treatment. METHODS: Four test sites on each forearm were randomly assigned to three skin damage models with the fourth sites on each forearm chosen as a control, undamaged site. Skin parameters were assessed using non-invasive methods. RESULTS: Sodium lauryl sulphate irritation caused the strongest damage with delayed reaction to the irritant. Tape stripping leads to highest initial skin barrier disruption but afterwards it showed the fastest skin recovery. Ultraviolet radiation did not affect skin barrier function, but it elevated skin erythema and melanin level. Tested preparation did not lead to changes in measured parameters. CONCLUSION: The skin of the participants had different response to three skin damage models with distinct changes of skin parameters and recovery. The trial was registered at ClinicalTrials.gov under the identifier NCT03783819.

Correlation of registered drug packs with Maastricht V/Florence Consensus Report and national treatment guidelines for management of Helicobacter pylori infection.

High prevalence of Helicobacter pylori infection, the complexity for its treatment, poor correlation of registered drug packs or poor patient adherence to the treatment may contribute to antibiotic resistance and healthcare costs. The aim of the present study was to investigate whether registered drug packs are in accordance with European and national guidelines for H pylori eradication with reference to the number of drug units. In this study, we considered treatment options for the management of H pylori infection recommended by the Maastricht V/Florence Consensus Report and by national guidelines in the United Kingdom (UK), Croatia, Italy and Slovenia for adults. Drugs proposed by the guidelines were identified in national drug databases in July of 2019. When considering correlation for 10-day treatment regimens, drug packs registered in Croatia could not be matched with recommendations for sequential therapies. A number of proposed treatments could not be matched due to small variety of drug packs in Croatia. Drug packs registered in the UK more often matched recommended 14-day treatment regimens and national guidelines. With reference to European guidelines, 10-day treatments could more frequently be matched in Italy and in Slovenia. Furthermore, results of this study indicate that there is smaller variety in drug pack sizes registered in Croatia and Slovenia when compared to UK and Italy. Considering poor correlation of drug packs with treatment guidelines for H pylori, adherence to antimicrobial treatment and proper disposal of antimicrobials is warrant. Discussing adherence to antimicrobial treatment with patients should be introduced as a standard of patient care and education.

Analysis of spontaneous reporting of suspected adverse drug reactions for non-analgesic over-the-counter drugs from 2008 to 2017.

BACKGROUND: Adverse drug reaction (ADR) reporting practices by health care professionals remain poor. Over-the-counter (OTC) drugs are perceived as safe; however, they can also cause ADRs. The objective of this study was to analyze ADR reporting for OTC drugs in a 10-year period, in order to evaluate frequency of ADRs, population that ADRs most affect and reporters of ADRs of OTC drugs in Croatia. METHODS: Spontaneously reported ADRs of non-analgesic OTC drugs, collected from January 2008 to December 2017 were analyzed. Data was obtained from Agency for Medicinal Products and Medical Devices of Croatia (HALMED). RESULTS: There were 547 ADRs of OTC drugs reported in total and an increase in number of reports through the years was observed. Pharmacists reported 45.4% of all ADRs, and were most frequent reporters (p < 0.001). In 2017 majority of reports, 62 (49.2%), were obtained from consumers. ADRs were most frequently observed in patients aged 70 years and older (15% of ADRs). Five percent of all reports were accidental exposures among children. CONCLUSIONS: Pharmacists most frequently reported ADRs of OTC drugs and consumers' awareness of ADR reporting has risen. Other health care professionals (e.g., nurses and dentists) must be offered proper education in order to improve reporting practice of ADRs. Health care professionals should address concerns about OTC drug safety in elderly and children.
