BACKGROUND:
Infertility is a burdensome, often overlooked condition. This study aimed to investigate the global distribution and trends in the burden of infertility from 1990 to 2021.
METHODS:
We obtained data on the prevalence and years lived with disability (YLDs) related to infertility from the Global Burden of Disease 2021 study and evaluated them by calculating the estimated annual percentage change in age-standardized rates. We investigated the relationship between sociodemographic index (SDI) and the burden of infertility on the global, regional, and national levels.
RESULTS:
In 2021, there were 143,261,562 female and 55,481,380 male infertility cases worldwide, respectively. In China, female and male infertility cases accounted for 23.59% and 21.47% of the global totals, reaching 33,795,944 and 11,909,889, respectively. Compared with 2019, the global number of female and male infertility cases increased by 5,286,227 in females and 2,017,271 in males. In contrast, China saw a decline in both female and male infertility cases, with reductions of 698,735 and 154,591, respectively. From 1990 to 2021, the age-standardized prevalence rate (ASPR) and age-standardized YLDs rate (ASYR) for female infertility both increased by 0.59% annually, whereas these two corresponding indicators for male infertility increased by 0.50% annually worldwide. The burden of female infertility was consistently higher than that of male infertility and demonstrated a faster rate of increase. East Asia had the highest ASPR and ASYR for female infertility, whereas Eastern Europe had the highest metrics for male infertility. A horizontal S-shaped association was observed between the SDI and ASPR and ASYR of infertility, with a rapid decline in the infertility burden when the SDI exceeded 0.7.
CONCLUSIONS
The global burden of infertility has increased over the years, with a higher burden on women and underdeveloped regions. These findings emphasize the need to prioritize healthcare for patients with infertility to address the rising burden.

OBJECTIVE:
To explore the current status and changing trends of the disease burden of traumatic brain injury (TBI) in China from 1990 to 2023, and to quantitatively assess the impact of different influencing factors on this disease burden, thereby providing references for the prevention of TBI.
METHODS:
Based on the 2023 Global Burden of Disease Study (GBD), indicators including incidence and years lived with disability (YLDs) were used to analyze the status and changing trends of TBI disease burden in China from 1990 to 2023. Additionally, the decomposition method established by Gupta was adopted to quantify the effects of population growth, population aging, age-specific incidence rate, and disease severity on YLDs.
RESULTS:
From 1990 to 2023, the age-standardized incidence rate and YLDs rate of TBI in China showed an overall upward trend, with a significant downward trend between 2015 and 2020, followed by a resumption of upward trend after 2020. The disease burden of TBI in males was higher than that in females, with a larger increase amplitude. The elderly population had higher TBI incidence rate and YLDs rate, also with a larger upward amplitude. Falls were the main cause of TBI in China, and the changing trend of the disease burden caused by falls was consistent with the overall trend of TBI disease burden; meanwhile, the elderly population bore a relatively high disease burden from falls. Taking 1990 as the baseline, the growth rates of YLDs in males and females in 2023 were 101.54% and 101.40%, respectively. For males, the proportions of YLDs growth attributed to population growth, population aging, age-specific incidence rate, and disease severity were 26.91%, 49.62%, 37.74%, and -12.73%, respectively; for females, the corresponding proportions were 28.85%, 57.69%, 27.65%, and -12.79%.
CONCLUSION
From 1990 to 2023, population aging had a significant impact on the disease burden of TBI in China. Strengthening the prevention and control of falls and paying close attention to males and the elderly population should be the key focuses of TBI prevention and control work in China in the future.

Chinese Journal of Traumatology 2020;23(6):351-355
PURPOSE:
One of the consequences of trauma-related injuries is disability. There are more than one billion people with disabilities worldwide. Disability in people reduces their quality of life. The goal of this study was to determine the rate of post-trauma stress and disability related to trauma in the population over 15 years old in Kashan during a solar year of 2018-2019.
METHODS:
This is a cross-sectional population-based study. A cluster sampling method was used in the city of Kashan, and 3880 persons were interviewed with individuals randomly selected in each household. If a person had trauma during one year ago, the World Health Organization Disability Assessment Schedule 2.0 and Post Trauma Stress Disorder (PTSD) Checklist were applied for further interview. Data were analyzed using Chi-square test or t-test.
RESULTS:
Among the 3880 participants residing in Kashan, 274 (7.1%) reported a history of traumatic injury during one year ago in 2018-2019. Incidence of all injuries was estimated to be 70.61 (62.60-78.70) per 1000 people. For the trauma population, 213 (77.7%) were male and 75.1% were married. About half of them (50.3%, 138/274) aged 21-39 years. The most common cause of injuries was related to traffic accidents: 140 (51.1%). Of the 274 trauma participants, 47 (17.2%) reported PTSD; 244 (89.1%) had a mild disability, and 30 (10.9%) reported moderate disability.
CONCLUSION
One of the main causes of disability in the human community is the traumatic injuries. According to the results of this study, 89.1% of trauma participants have sustained at last mild disability following trauma. These people require follow-up and post-treatment support. It should be noted that psychological complications such as PTSD are as significant as physical symptoms.

BACKGROUND: Several studies have been conducted regarding people with disabilities, however no studies have estimated the disease burden due to premature death. As such, we aimed to compare the years of life lost (YLLs) due to premature death between a population with disabilities and the total population of Korea. METHODS: To calculate the YLLs in people with disabilities, we combined disability registration data from the 2002–2011 Ministry of Health and Welfare of Korea and the causes of mortality data by Statistics Korea for 3,158,231 people. RESULTS: YLLs of people with disabilities were 517,337, which accounted for 23.4% of YLLs of the total population. YLLs per 100,000 people with disabilities were approximately 3.8 times higher than those in the total Korean population. Ischemic stroke was associated with the highest YLLs per 100,000 people, followed by ischemic heart disease, hemorrhagic, and other non-ischemic stroke, diabetes mellitus, and self-harm. Among individuals with physical disabilities, ischemic heart disease was associated with the highest YLLs. For intellectual disability, epilepsy contributed to the most YLLs. For individuals with mental disability, self-harm was the largest contributor to YLLs. CONCLUSION: The burden of disease was higher in the population with disabilities than that in the general population. Cardiovascular diseases and cancer had a higher burden of disease than did other diseases in the population with disabilities; thus, overall, non-communicable diseases have a higher burden of disease than communicable diseases or injuries in the population with disabilities than in the general population.

Objective To provide reference for further perfection and revision of standards relevant to limb injury by comparing the evaluation results of different disability standards of long bone fracture. Methods Thirty cases were selected from the long bone fracture cases accepted by our institution in 2018. These cases include 5 cases of shoulder, elbow, wrist, hip, knee, ankle joints, respectively, to investigate the degree of loss of function of joints after long bone fracture. Disability evaluation was made according to Classification of the Impairment Related To Injury (hereinafter referred to as Classification), Assessment for Body Impairment of the injured in road traffic accidents (now repealed, hereinafter referred to as original Road Standard) and Identifying Work Ability-Gradation of Disability Caused by Work-related Injuries and Occupational Diseases (hereinafter referred to as Work Standard). The disability evaluation results of every domestic standard were compared with the joint damage rate of Guides to the Evaluation of Permanent Impairment (hereinafter referred to as GEPI). Results The functional loss rate of joints (except ankle) was 26%-48%,and the ankle functional loss rate was 51%-64%. The mean value of GEPI joint impairment rate of the joints was 13%-22%, with the fluctuation range less than 10%. The rate of level 10 disability was 100% according to the Classification. The rate of level 10 disability was 27%, the rate of level 9 disability was 6% and 67% were not disabled according to the original Road Standard. The rate of level 10 disability was 10% according to the Work Standard and 90% had a disability above level 10 (47% were classified as level 7 disability). Conclusion The people with limb joint dysfunction in this study had evaluation results with a smaller fluctuation range and better consistency according to the Classification and GEPI. The evaluation results according to the original Road Standard and the Work Standard has a less consistency. The Classification is more similar to GEPI and is more reasonable.

8.Comparative Analysis of Visual System Disability Evaluation Criteria between China and the United States.
Journal of Forensic Medicine 2019;35(5):607-612
Gradation of Disability in Human Body Injuries (hereinafter referred to as Gradation) has been released and used since January 2017, and has become the most widely used standard in forensic science practice. This paper calculates and rates the visual system evaluation provisions of the current domestic disability evaluation criteria represented by the Gradation which used the methods of Guides to the Evaluation of Permanent Impairment (hereinafter referred to as GEPI) issued by American Medical Association (AMA). Through comparing, a good correlation between the provisions in Gradation and whole person impairment rating index in GEPI was shown. On the basis of this, suggestions are put forward to amend some provisions of Gradation, in order to provide reference for the revision and further improvement of domestic standards and provisions.

OBJECTIVE: To evaluate the utility of using the Personal Assistance Services classification system (PAS-CS) that examines individuals with disabilities for services and government funding. To this end, this study also tests for significant differences in PAS-CS scores across disability grades and disability types. METHODS: A retrospective analysis was conducted using the 2014 National Survey on People with Disabilities (NSPD) data set. We selected patients with three types of disabilities (physical disabilities, brain lesions, and visual impairments). We compared the average PAS-CS scores of patients with different disability types and grades using general linear models with multiple comparisons. RESULTS: A total of 4,810 patients were included in the analysis. Patients with brain lesions had the highest average PAS-CS scores in activities of daily living (ADL) and instrumental activities of daily living (IADL) domains. Patients with visual impairments had the highest average scores in ‘Disease-specific disability’ and ‘Social-environment’ domains. For patients with physical disabilities and visual impairments, no PAS-CS domains were significantly different between patients with disability grade III and those with disability grade IV (p>0.05). CONCLUSION: The PAS-CS scores of disability grades were not equivalent among individuals with different disability types. The Korean Ministry of Health and Welfare currently only considers certain disability grades for PAS preeligibility, as a result disregarding the characteristics of different disability types. Thus, the current PAS-CS requires modifications.

BACKGROUND: This study retrospectively investigated outcomes following dental implantation in patients with special needs who required general anesthesia to enable treatment. METHODS: Patients underwent implant treatment under general anesthesia at the Clinic for the Disabled in Seoul National University Dental Hospital between January 2004 and June 2017. The study analyzed medical records and radiographs. Implant survival rates were calculated by applying criteria for success or failure. RESULTS: Of 19 patients in the study, 8 were males and 11 were females, with a mean age of 32.9 years. The patients included 11 with mental retardation, 3 with autism, 2 with cerebral palsy, 2 with schizophrenia, and 1 with a brain disorder; 2 patients also had seizure disorders. All were incapable of oral self-care due to serious cognitive impairment and could not cooperate with normal dental treatment. A total of 27 rounds of general anesthesia and 1 round of intravenous sedation were performed for implant surgery. Implant placement was performed in 3 patients whose prosthesis records could not be found, while 3 other patients had less than 1 year of follow-up after prosthetic treatment. When the criteria for implant success or failure were applied in 13 remaining patients, 3 implant failures occurred in 59 total treatments. The cumulative survival rate of implants over an average of 43.3 months (15-116 months) was 94.9%. CONCLUSIONS: For patients with severe cognitive impairment who are incapable of oral self-care, implant treatment under general anesthesia showed a favorable prognosis.
