Various comorbidities and multimorbidity frequently occur in chronic obstructive pulmonary disease (COPD), leading to the overload of health care systems and increased mortality. We aimed to assess the impact of COPD on the probability and clustering of comorbidities. The cross-sectional analysis of the nationwide Lithuanian database was performed based on the entries of the codes of chronic diseases. COPD was defined on the code J44.8 entry and six-month consumption of bronchodilators. Descriptive statistics and odds ratios (ORs) for associations and agglomerative hierarchical clustering were carried out. 321,297 patients aged 40–79 years were included; 4834 of them had COPD. A significantly higher prevalence of cardiovascular diseases (CVD), lung cancer, kidney diseases, and the association of COPD with six-fold higher odds of lung cancer (OR 6.66; p < 0.0001), a two-fold of heart failure (OR 2.61; p < 0.0001), and CVD (OR 1.83; p < 0.0001) was found. Six clusters in COPD males and five in females were pointed out, in patients without COPD—five and four clusters accordingly. The most prevalent cardiovascular cluster had no significant difference according to sex or COPD presence, but a different linkage of dyslipidemia was found. The study raises the need to elaborate adjusted multimorbidity case management and screening tools enabling better outcomes.

Purpose: To evaluate the implanted legislation and regulations in Jordan, in order to minimize nanotechnology research-related health concerns. Methods: In the first part, all nanotechnology published research in Scopus database and the Jordanian National Database for Researchers were mined. The growth in nanotechnology research was analyzed by calculating the relative growth rate (RGR), doubling time (DT), and compound annual growth rate (CAGR). Thereafter, the results were compared to global preferences. Furthermore, this research explored all possible factors that may influence decision-makers and health policies in Jordan. Results: Data analysis showed that the quantity of nanotechnology research in Jordan is exponentially increasing with RGR (1.96), DT (0.37), and CAGR (33 %) very close to the figures obtained worldwide. The trend line analysis (R2 = 0.9638) expected that more than 65 % of nanotechnology research will be produced within the next 5 years. Moreover, no legislation has been adapted in Jordan to regulate nanotechnology research and industry. Conclusions: Adopting nanotechnology without having any corresponding legislation constitutes a violation of the ethical codes of research, and ignorance of public safety. Moreover, the research suggests a set of steps to organize the crafting of nanotechnology and research in Jordan, and other similar contexts in developing countries.

Aims A recent report from France suggested an association between the use of cobalt-chrome femoral heads in total hip arthroplasties (THAs) and an increased risk of dilated cardiomyopathy and heart failure. Cobalt-chrome is a commonly used material in orthopaedic implants. If the reported association is causal, the consequences would be significant given the millions of joint replacements and other orthopaedic procedures in which cobalt-chrome is used annually. We examined whether cobalt-chrome-containing THAs were associated with an increased risk of all-cause mortality, heart outcomes, cancer, and neurodegenerative disorders in a large national database. Methods Data from the National Joint Registry was linked to NHS English hospital inpatient episodes for 374,359 primary THAs with up to 14.5 years follow-up. We excluded any patients with bilateral THAs, knee replacements, indications other than osteoarthritis, aged under 55 years, and diagnosis of one or more outcome of interest before THA. Implants were grouped as either containing cobalt-chrome or not containing cobalt-chrome. The association between implant construct and the risk of all-cause mortality and incident heart failure, cancer, and neurodegenerative disorders was examined. Results There were 158,677 individuals (42.4%) with an implant containing cobalt-chrome. There were 47,963 deaths, 27,332 heart outcomes, 35,720 cancers, and 22,025 neurodegenerative disorders. There was no evidence of an association that patients with cobalt-chrome implants had higher rates of any of the outcomes. Conclusion Cobalt-chrome-containing THAs did not have an increased risk of all-cause mortality, or clinically meaningful heart outcomes, cancer or neurodegenerative disorders into the second decade post-implantation. Our findings will help reassure clinicians and the increasing number of patients receiving primary THA worldwide that the use of cobalt-chrome containing implants is not associated with significant adverse systemic effects.

Objectives: Due to the long lag-time for health outcomes, historical asbestos exposure measurements are valuable to support assessments of associated occupational health effects, and also to assess time trends and effects of preventive measures. Methods: Different sources of stored data were collated, assessed and refined to create a harmonized database on historical asbestos fibre concentrations measured in specific work tasks and different industries. The final database contains 9236 asbestos measurements from Danish workplaces collected from 1971 to 1997. Results: The geometric mean of asbestos concentrations in different occupations and tasks ranged from 0.003 to 35 fibres cm−3. Highest concentrations were registered during handling of asbestos products in the construction services during the period 1981–1997. Although all the measured asbestos exposures without the use of respiratory equipment by the worker in the period of 1971–1997 exceeded the current 8-h time-weighted average exposure limit of 0.1 fibres cm−3, the majority of samples collected in the earlier period of 1971 to 1980 did not exceed the exposure limit of 2 fibres cm−3, which was in place at the time. All exposure data obtained from 1980 and onwards were found to be one seventh of the mean fibre concentrations in the previous measurement period. The impact of time shows a clear exponentially decreasing trend-line. Conclusions: Despite limitations in coverage of different occupations and tasks associated with the inventoried historical asbestos measurements, the data are helpful to identify specific work scenarios within an industry, where relatively high asbestos exposure levels may still occur or have occurred from 1971 to 1997.

Összefoglaló. Bevezetés: A sokszínű tünetspektrummal jellemezhető DiGeorge-szindróma leggyakoribb oka a 22q11.2-microdeletio; incidenciája 1/4000–6000. Célkitűzés: A DiGeorge-szindrómára gyanús hazai betegcsoport 22q11.2-microdeletióval társult tüneteinek/panaszainak részletes feltérképezése, a betegség incidenciájának becslése és egy magyarországi 22q11.2-microdeletiós szindróma regiszter létrehozása. Módszer: 2005 és 2019 között a Semmelweis Egyetem II. Gyermekgyógyászati Klinikájára DiGeorge-szindróma gyanújával beutalt és a Veleszületett Rendellenességek Országos Nyilvántartása által regisztrált DiGeorge-szindrómás betegek adatait dolgoztuk fel. A fenotípusjegyeket a Humán Fenotípus Ontológia kódrendszer alapján határoztuk meg. Eredmények: A vizsgálatba 114, igazolt DiGeorge-szindrómás és 113, FISH-vizsgálattal microdeletiót nem hordozó, de klinikailag a DiGeorge-szindróma tüneteit mutató beteget vontunk be. A diagnózis felállításakor a betegek átlagéletkora 5,88 (± 9,66 SD) év volt, eddig a betegek 54,9%-a legalább egy szívműtéten átesett. A betegek leggyakoribb tünetei a kamrai sövényhiány, a mélyen ülő fülek, a gótikus szájpad, a motoros fejlődési elmaradás és a visszatérő fertőzések voltak. Megbeszélés: A DiGeorge-szindróma becsült incidenciája hazánkban 1/12 500, közöttük magas a többszörösen veszélyeztetett újszülöttek és a műtéti korrekcióra szorulók aránya. A diagnózis hazánkban 2–3 évvel korábban történik a nemzetközi átlaghoz viszonyítva. Következtetés: A létrehozott regiszterünk alapján Magyarországon a kórkép aluldiagnosztizált. Minden conotruncalis szívfejlődési rendellenesség vagy jelentős kamrai sövényhiány esetén citogenetikai vizsgálat javasolt a DiGeorge-szindróma felmerülő gyanúja miatt. Negatív lelet esetén az atípusos töréspontú microdeletiók azonosítására komparatív genomiális hibridizáció vagy multiplex ligatiofüggő próbaamplifikációs vizsgálat javasolt. A betegek számára multidiszciplináris ellátás szükséges, III-as progresszivitási szintű újszülött intenzív részlegen, gyermekkardiológus és klinikai genetikus részvételével. Orv Hetil. 2022; 163(1): 21–30. Summary. Introduction: The 22q11.2 microdeletion syndrome is the most common cause of DiGeorge syndrome, showing a wide phenotypic spectrum and has an estimated incidence of 1/4000–6000 livebirths. Objective: Detailed characterization of the clinical signs/symptoms associated with 22q11.2 deletion, estimation of the national incidence via establishing a Hungarian register. Method: Retrospective data between 2005 and 2019 from the 2nd Department of Paediatrics, Semmelweis University and from national database of congenital anomalies were obtained. Phenotypic abnormalities were described using the Human Phenotype Ontology nomenclature. Results: A cohort of 114 DiGeorge patients and 113 patients negative for FISH testing were included. The mean age of patients at diagnosis was 5.88 (± 9.66 SD) years and 54.9% of patients had at least one heart surgery until diagnosis. The main identified symptoms were ventricular septal defect, low-set ears, recurrent infections, high narrow palate and motor development delay. Discussion: The estimated incidence of DiGeorge syndrome in Hungary is 1/12 500 births, the frequency of infants at high risk and in need for surgery is high. Diagnosis is established 2–3 years earlier as compared to the international average. Conclusion: Based on the established Hungarian register, the incidence is lower compared to international data. In the case of conotruncal heart anomaly and ventricular septal defects, cytogenetic testing is recommended for the increased probability of DiGeorge syndrome. For second-tier testing, comparative genome hybridization or multiplex ligation-dependent probe amplification are recommended to identify atypical microdeletions. Newborns with DiGeorge syndrome require special care in perinatal intensive centers including pediatric cardiology and genetic counseling. Orv Hetil. 2022; 163(1): 21–30.

The majority of major injuries admitted to hospital are now in older people, with a fall from standing height being the most common reason for injury. Our study will look at older adults admitted to hospital with serious traumatic injuries across England. It will aim to work out firstly if there is an effect of frailty on peoples' survival after injury. Frailty is the reserve a person has to cope with illness and is a measure of a person slowing down over time usually due to the collection of lots of health problems. Secondly, we will look at if being seen by an old age specialist (geriatrician) has an effect on a person's chances of surviving their injuries. The records we will look at are held collected routinely and held by a national database run by the Trauma and Audit Research Network (TARN) from the University of Manchester. They collect information from the 22 centres of major trauma excellence around the country and help researchers to work with them to access the anonymous data for specific research questions. We aim to use these results to help clinicians and health systems to improve how the fund and deliver care for older people.

Abstract Background The survival rate of chronic dialysis patients in Japan remains the highest worldwide, so there is value in presenting Japan’s situation internationally. We examined whether aggregate figures on dialysis patients in the National Database of Health Insurance Claims and Special Health Checkups of Japan (NDB), which contains data on insured procedures of approximately 100 million Japanese residents, complement corresponding figures in the Japanese Society for Dialysis Therapy Renal Data Registry (JRDR). Methods Subjects were patients with medical fee points for dialysis recorded in the NDB during 2014–2018. We analyzed annual numbers of dialysis cases, newly initiated dialysis cases– and deaths. Results Compared with the JRDR, the NDB had about 6–7% fewer dialysis cases but a similar number of newly initiated dialysis cases. In the NDB, the number of deaths was about 6–10% lower, and the number of hemodialysis cases was lower, while that of peritoneal dialysis cases was higher. The cumulative survival rate at dialysis initiation was approximately 6 percentage points lower in the NDB than in the JRDR, indicating that some patients die at dialysis initiation. Cumulative survival rate by age group was roughly the same between the NDB and JRDR in both sexes. Conclusion The use of the NDB enabled us to aggregate data of dialysis patients. With the definition of dialysis patients used in this study, analyses of concomitant medications, comorbidities, surgeries, and therapies will become possible, which will be useful in many future studies.

Objective: During the outbreak of COVID-19,several coping strategies were implemented including strengthened social distancing, wearing masks and hand hygiene. Thisinfection control method might have been effective for other respiratory infections; however, it had not yet been clearly revealed. Therefore,we investigatedwhetherthe incidence of infectious respiratory diseases has reduced after excluding the effect of decreased medical utilization because of COVID-19 control measures.Design or methods: We used the Korean national claims data and analyzed incidences of acute respiratory infections (ARI) and diseases except ARI. The incidence rates of winter 2019 and 2020 were compared.Results: Excluding ARI,the reduction in overall hospital visits decreased by only 2%; however,the number of visits due to ARI decreased by 13%, and the number of visits due to influenza particularly decreased by 26%.Conclusions: Using national database, this study confirmed that a significant reduction in ARI, including influenza, occurred during the COVID-19 pandemic. Infection control measures including nationally enforced social distancing may be effective in controlling the transmission of other respiratory infections. Further studies are necessary to clarify the causal relationship.
