The impact of comorbidities on prolonged mechanical ventilation in patients with chronic obstructive pulmonary disease.

BACKGROUND: In patients with chronic obstructive pulmonary disease (COPD) and acute respiratory failure, approximately 10% of them are considered to be at high risk for prolonged mechanical ventilation (PMV, > 21 days). PMV have been identified as independent predictors of unfavorable outcomes. Our previous study revealed that patients aged 70 years older and COPD severity were at a significantly higher risk for PMV. We aimed to analyze the impact of comorbidities and their associated risks in patients with COPD who require PMV. METHODS: The data used in this study was collected from Kaohsiung Medical University Hospital Research Database. The COPD subjects were the patients first diagnosed COPD (index date) between January 1, 2012 and December 31, 2020. The exclusion criteria were the patients with age less than 40 years, PMV before the index date or incomplete records. COPD and non-COPD patients, matched controls were used by applying the propensity score matching method. RESULTS: There are 3,744 eligible patients with COPD in the study group. The study group had a rate of 1.6% (60 cases) patients with PMV. The adjusted HR of PMV was 2.21 (95% CI 1.44-3.40; P < 0.001) in the COPD patients than in non-COPD patients. Increased risks of PMV were found significantly for patients with diabetes mellitus (aHR 4.66; P < 0.001), hypertension (aHR 3.20; P = 0.004), dyslipidemia (aHR 3.02; P = 0.015), congestive heart failure (aHR 6.44; P < 0.001), coronary artery disease (aHR 3.11; P = 0.014), stroke (aHR 6.37; P < 0.001), chronic kidney disease (aHR 5.81 P < 0.001) and Dementia (aHR 5.78; P < 0.001). CONCLUSIONS: Age, gender, and comorbidities were identified as significantly higher risk factors for PMV occurrence in the COPD patients compared to the non-COPD patients. Beyond age, comorbidities also play a crucial role in PMV in COPD.

Precision and Robust Models on Healthcare Institution Federated Learning for Predicting HCC on Portal Venous CT Images.

Hepatocellular carcinoma (HCC), the most common type of liver cancer, poses significant challenges in detection and diagnosis. Medical imaging, especially computed tomography (CT), is pivotal in non-invasively identifying this disease, requiring substantial expertise for interpretation. This research introduces an innovative strategy that integrates two-dimensional (2D) and three-dimensional (3D) deep learning models within a federated learning (FL) framework for precise segmentation of liver and tumor regions in medical images. The study utilized 131 CT scans from the Liver Tumor Segmentation (LiTS) challenge and demonstrated the superior efficiency and accuracy of the proposed Hybrid-ResUNet model with a Dice score of 0.9433 and an AUC of 0.9965 compared to ResNet and EfficientNet models. This FL approach is beneficial for conducting large-scale clinical trials while safeguarding patient privacy across healthcare settings. It facilitates active engagement in problem-solving, data collection, model development, and refinement. The study also addresses data imbalances in the FL context, showing resilience and highlighting local models' robust performance. Future research will concentrate on refining federated learning algorithms and their incorporation into the continuous implementation and deployment (CI/CD) processes in AI system operations, emphasizing the dynamic involvement of clients. We recommend a collaborative human-AI endeavor to enhance feature extraction and knowledge transfer. These improvements are intended to boost equitable and efficient data collaboration across various sectors in practical scenarios, offering a crucial guide for forthcoming research in medical AI.

Robotic partial nephrectomy for renal tumor: The pentafecta outcomes of a single surgeon experience.

PURPOSE: This study investigated the oncological and functional surgical outcomes for patients with renal tumor who underwent robot-assisted partial nephrectomy (PN) by a single surgeon in Taiwan from 2006 to 2019. METHODS: This retrospective study assessed patients who underwent robot-assisted PN for renal tumor. Patient data were analyzed for age, sex, body mass index, operative time and total ischemic time, surgical margin (positive/negative), and surgical complications. To evaluate functional and oncological outcomes, achievement of trifecta, and pentafecta criteria was used. Trifecta criteria were defined as a negative surgical margin, no postoperative complications, warm ischemia time <25 min. Pentafecta criteria were the trifecta criteria, >90% preservation of estimated glomerular filtration rate (eGFR) preservation, and no stage progression of chronic kidney disease at 1-year follow-up. RESULTS: Of 101 patients who received robot-assisted PN, the most common type of renal tumor was clear cell renal cell carcinoma (RCC) (38%), followed by angiomyolipoma (26%). Patient characteristics were mean age 54.59 ± 13.8 years; mean RENAL Nephrometry score 6.63 ± 2.16; mean operative time 102.34 ± 50.06 min; and warm ischemia time 20.01 ± 14.12 min. The mean eGFR was 104.43 ± 31.73 mL/min/1.73 m2 preoperatively and 89.39 ± 32.3 mL/min/1.73 m2 postoperatively. Pathologic evaluation showed malignant tumors in 57 patients, among whom achievement of trifecta criteria occurred for 39 (68.42%) and pentafecta criteria for 18 (31.57%). Operation time was the only predictor for pentafecta achievement. CONCLUSION: Robotic PN is a safe and effective approach for patients with renal tumor that can preserve most renal function and achieve oncological control. Pentafecta criteria can be used to more clearly define the surgical outcome of RAPN.

Design, synthesis and biological activity of novel triketone herbicides containing natural product fragments.

4-Hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, HPPD) belongs to the non-heme Fe2+ - containing enzyme family and is an important enzyme in tyrosine decomposition. HPPD is crucial to the discovery of novel bleaching herbicides. To develop novel HPPD inhibitor herbicides containing the ß-triketone motif, a series of 4-hydroxyl-3-(substituted aryl)-pyran-2-one derivatives were designed using the active fragment splicing method. The title compounds were synthesized and characterized through infrared spectroscopy (IR), 1H nuclear magnetic resonance (1H NMR), 13C nuclear magnetic resonance (13C NMR), and high-resolution mass spectrometry (HRMS). The X-ray diffraction method determined the single crystal structure of I-17. Preliminary bioassay data revealed that several novel compounds, especially I-12 and II-3, showed excellent herbicidal activity against broadleaf and monocotyledonous weeds at a dose of 150 g ai/ha. The results of crop selectivity and carotenoids determination indicated that compound I-12 is more suitable for wheat and cotton fields than mesotrione. Additionally, compound II-3 is safer for soybeans and peanuts than mesotrione. The inhibitory activity of Arabidopsis thaliana HPPD (AtHPPD) verified that compound II-3 showed the most activity with an IC50 value of 0.248 µM, which was superior to that of mesotrione (0.283 µM) in vitro. The binding mode of compound II-3 and AtHPPD was confirmed through molecular docking and molecular dynamics simulations. This study provides insights into the future development of natural and efficient herbicides.

Impacts of Mir146a Genotypes on Bladder Cancer Risk in Taiwan.

The aim of this study was to investigate the association between single-nucleotide polymorphisms (SNPs) in mir146a and mir196a and bladder cancer (BLCA) risk in Taiwan. The genotypes of mir146a rs2910164 and mir196a rs11614913 were determined in 375 BLCA patients and 375 healthy controls using PCR-RFLP methodology, and their associations with BLCA risk were evaluated. The study also measured the serum expression level of mir146a using quantitative RT-PCR. The results showed that the distributions of CC, CG and GG genotypes of mir146a rs2910164 were 31.7%, 45.6% and 22.7% in the control group, and 21.9%, 44.3% and 33.8% in the case group, respectively. In logistic regression analyses, the heterozygous variant genotype CG carriers showed a marginally significant association with increased BLCA risk (OR = 1.41, 95% CI = 0.99-2.01), while the homozygous variant genotype GG carriers had a 2.17-fold increased risk of BLCA (OR = 2.17, 95%CI = 1.46-3.21). Moreover, carriers of the GG/CG genotypes had significantly higher serum levels of mir146a than those with the CC genotype (p < 0.0001), indicating a genotype-phenotype correlation. In contrast, mir196a rs11614913 was not associated with BLCA risk. Therefore, the genotypes of mir146a rs2910164 may serve as a useful biomarker for predicting the risk of BLCA.

High-power, multi-junction, 905†nm vertical-cavity surface-emitting laser with an AlGaAsSb electron-blocking layer.

We report high-power multi-junction vertical-cavity surface-emitting lasers (VCSELs) with a significantly suppressed carrier leakage issue under high injection current and temperature. By carefully optimizing the energy band structure of quaternary AlGaAsSb, we obtained a 12-nm-thick AlGaAsSb electron-blocking layer (EBL) with a high effective barrier height (∼122 meV), a low compressive strain (∼0.99%), and a reduced electronic leakage current. The resulting three-junction (3J) 905 nm VCSEL with the proposed EBL exhibits an improved maximum output power (∼46.4 mW) and power conversion efficiency (PCE; ∼55.4%) during room-temperature operation. Also, it was found from thermal simulation that the optimized device shows more advantages over the original device during high-temperature operation. The type-II AlGaAsSb EBL provided an excellent electron-blocking effect and would be a promising strategy for multi-junction VCSELs to realize high-power applications.

Terminally ill patients' and their relatives' experiences and behaviors regarding complementary and alternative medicine utilization in hospice palliative inpatient care units: a cross-sectional, multicenter survey.

BACKGROUND: Terminally ill patients often experience exacerbations of diseases that render mainstream medicine ineffective in relieving symptoms, prompting attempts at complementary and alternative medicine (CAM). This study collected data from terminally ill patients and their relatives to determine differences between CAM use, behavioral patterns, and perceptions of health information about CAM. METHODS: A cross-sectional design using a self-administered questionnaire was adopted. Eight medical institutions in Taiwan with inpatient hospice palliative care units were chosen. Ninety-two terminally ill patients and 267 relatives met the inclusion criteria. The questions concerned the experience of CAM use, the kinds of products/services CAM provided, the purpose of CAM use, the source of CAM information, and the perceptions and attitudes toward CAM. RESULTS: Both terminally ill patients and their relatives have a high proportion of lifetime and one-year prevalence of CAM use (88.0% vs. 88.4%; p = 0.929). CAM use for musculoskeletal and neurological discomfort is higher among terminally ill patients than among their relatives. Relatives/friends are the most frequent sources of information on CAM (53.3% vs. 62.2%; p = 0.133). The percentage of terminally ill patients who discontinued mainstream medical treatment because of CAM use was higher than that of their relatives (18.5% vs. 9.3%; p = 0.026). More than half the terminally ill patients and their relatives had never been asked about CAM by medical staff (64.1% vs. 66.7%), nor had they informed medical professionals about the use of CAM products and services (63% vs. 66.9%). Random inquiries by medical professionals may be associated with increased disclosure of CAM use (terminally ill patients: odds ratio, 9.75; 95% confidence interval, 1.97-48.35 vs. relatives: odds ratio, 5.61; 95% confidence interval, 2.66-11.83). CONCLUSIONS: The high prevalence and concealment of CAM use in terminally ill patients should be considered. Medical professionals should establish a friendly and barrier-free communication model, encourage patients to share CAM experiences, and provide evidence-based information on the use of CAM products and services, to reduce the potential damage caused by harmful use.

Association of Matrix Metalloproteinase-7 Genotypes With Prostate Cancer Risk.

BACKGROUND/AIM: Prostate cancer is one of the most commonly diagnosed malignancies among males worldwide. It has been shown that MMP-7 gene is closely correlated with prostate carcinogenesis. However, the role of the MMP-7 genotypes has been seldom examined among prostate cancer patients. Therefore, the purpose of the study was to evaluate the contribution of MMP-7 promoter genotypes A-181G (rs11568818) and C-153T (rs11568819) to prostate cancer risk in Taiwan. MATERIALS AND METHODS: Two hundred and eighteen prostate cancer patients and 436 sex- and age-matched healthy controls were genotyped for MMP-7 rs11568818 and rs11568819 by polymerase chain reaction-restriction fragment length polymorphism and direct sequencing methodologies. RESULTS: The percentages of wild-type AA, and variant AG and GG genotypes on MMP-7 rs11568818 were 85.3, 13.5, and 1.2% among the prostate cancer cases and 87.6, 10.1, and 2.3% among the healthy controls, respectively (p for trend=0.2557). Interestingly, no MMP-7 rs11568819 genotypes were identified among Taiwanese. The allelic frequency distribution also showed that the variant G allele of MMP-7 rs11568818 seemed not to be a determinant of prostate cancer risk (p=0.7977). There was no joint effect between the genotypes of MMP-7 rs11568818 and age and smoking status on prostate cancer risk. CONCLUSION: rs11568818 and rs11568819 at MMP-7 promoter region, played no role in determining personal susceptibility to prostate cancer in Taiwan.

Design and Analysis of Small Size Eddy Current Displacement Sensor.

A systematic method is employed for the design and analysis of a small size eddy current (EC) displacement sensor. Simulations are first performed to determine the optimal winding structure and dimensions of the sensor. A linear-fitting approach is then developed for converting the AC displacement signal of the sensor to a DC signal. Finally, a compensation method is proposed for mitigating the temperature drift of the EC sensor under different working temperatures. The experimental results show that the proposed sensor has a sensitivity of approximately 3 µm, a working temperature range of 25-55 °C, and a linearity of ±1.025%.

Developing New Treatment Options for Castration-Resistant Prostate Cancer and Recurrent Disease.

Prostate cancer (PCa) is a major diagnosed cancer among men globally, and about 20% of patients develop metastatic prostate cancer (mPCa) in the initial diagnosis. PCa is a typical androgen-dependent disease; thus, hormonal therapy is commonly used as a standard care for mPCa by inhibiting androgen receptor (AR) activities, or androgen metabolism. Inevitably, almost all PCa will acquire resistance and become castration-resistant PCa (CRPC) that is associated with AR gene mutations or amplification, the presence of AR variants, loss of AR expression toward neuroendocrine phenotype, or other hormonal receptors. Treating CRPC poses a great challenge to clinicians. Research efforts in the last decade have come up with several new anti-androgen agents to prolong overall survival of CRPC patients. In addition, many potential targeting agents have been at the stage of being able to translate many preclinical discoveries into clinical practices. At this juncture, it is important to highlight the emerging strategies including small-molecule inhibitors to AR variants, DNA repair enzymes, cell survival pathway, neuroendocrine differentiation pathway, radiotherapy, CRPC-specific theranostics and immune therapy that are underway or have recently been completed.

Impact of SARS-CoV-2 transmission-based precautions on inpatient management of general medical patients.

This audit reviewed the impact on access to routine medical care and adverse outcomes in patients with suspected SARS-CoV-2 infection managed on a 'COVID-19' (CV) ward compared with a general medicine ward at Box Hill Hospital, Victoria. Data were collected at two time points to capture changes associated with onsite testing. We found no healthcare delays from admission to CV wards and observed faster exits from CV wards with improved testing efficiency. This critical finding is relevant as Victoria manages a third wave of infections.

Internationalisation of general practice journals: a bibliometric analysis of the Science Citation Index database.

Research plays a crucial role in the development of primary health care. Researchers in other specialities have studied the internationalisation of their journals, but no such study has been conducted for general practice. The aim of this study was to analyse the volume of publication and internationalisation of general practice journals indexed in the Science Citation Index (SCI) database in 2019. Of the total 1573 articles and reviews in 19 journals indexed under the subject category of 'primary health care' in the SCI database, 86.4% (n = 1359) were published in four English-speaking countries (32.8% in seven US journals, 34.8% in five UK journals, 12.5% in two Australian journals and 6.4% in one Canadian journal) and 40.6% (n = 639) were authored or coauthored by authors from a country other than that in which the journal was published. There was a significant (P < 0.05) relationship between the country of publication and the degree of internationalisation of the journal. The degree of internationalisation of general practice journals varied from 94.2% for family practice to 2.0% for primary care. There are wide disparities in internationalisation among different countries and general practice journals. There is much room for improvement in the internationalisation of general practice journals in the SCI database.

Efficacy of robot-assisted arthroscopic anterior cruciate ligament reconstruction / 中华创伤杂志

Objective:To compare the clinical efficacy of robot-assisted and simple arthroscopic reconstruction of anterior cruciate ligament (ACL).Methods:A retrospective cohort study was conducted to analyze the clinical data of 37 patients with ACL tear admitted to Honghui Hospital of Xi′an Jiaotong University from January 2020 to September 2020. There were 24 males and 13 females, aged 16-45 years［(30.7±9.8)years］. A total of 17 patients were treated by robot-assisted ACL reconstruction (robot-assisted group), and 20 patients by simple arthroscopic ACL reconstruction (simple arthroscopy group). The operation time, number of guide wire drilling, positional accuracy of bone tunnel (distance between the central point of bone tunnel and ideal anatomical point) and perioperative complications were compared between the two groups. Knee stability was evaluated by Lachman test and KT-2000 measurement, and knee function by Lysholm score, International Knee Documentation Committee (IKDC) score and range of motion of joint flexion and extension before operation, at 4 months after operation and at the last follow-up.Results:All patients were followed up for 12-18 months［(13.1±4.1)months］. The operation time in robot-assisted group was (83.8±11.3)minutes, significantly longer than (50.4±9.1)minutes in simple arthroscopy group ( P<0.01). The number of guide wire drilling in robot-assisted group was (2.2±0.5)times, less than (2.5±0.4)times in simple arthroscopy group ( P<0.05). The distance between the central point of bone tunnel and ideal anatomical point was (1.3±0.3)mm in robot-assisted group, not significantly different from (1.4±0.3)mm in simple arthroscopy group ( P>0.05). There were no perioperative complications in both groups. The two groups showed no significant differences in Lachman test, KT-2000 measurement, Lysholm score, IKDC score and range of motion of joint flexion and extension before operation, at 4 months after operation and at the last follow-up (all P>0.05). The above indices in both groups were significantly improved at 4 months after operation and at the last follow-up as compared with those before operation (all P<0.01), and both groups showed no significant difference in the above indexes at 4 months after operation and at the last follow-up as compared with those before operation (all P>0.05). Conclusion:Compared with simple arthroscopic ACL reconstruction, robot-assisted ACL reconstruction can prepare a bone tunnel once with good location and direction in one time and achieve similar results in stability and functional recovery of the joint except for slightly longer operation time.

With the development of neoadjuvant therapy, the treatment of pancreatic cancer has entered the era of comprehensive diagnosis and treatment consisting of surgery, chemo-therapy and radiotherapy. In recent years, the concept of 'total neoadjuvant therapy' has become one of the important treatment methods for locally advanced rectal cancer. The authors focus on pancrea-tic cancer, introduce the development status of total neoadjuvant therapy in pancreatic cancer and summarize the current controversies and challenges in the application of total neoadjuvant therapy in pancreatic cancer, in order to further standardize the diagnosis and treatment of pancreatic cancer and improve the overall level of pancreatic cancer treatment in China.

Ultraviolet Light-Activated Charge Modulation Heterojunction for Versatile Organic Thin Film Transistors.

Organic thin film transistors (OTFTs) are a promising technology for the application of photosensors in smart wearable devices. Light-induced electrical behavior of OTFTs is explored to achieve diverse functional requirements. In most studies, OTFTs show an increased drain current (ID) under light irradiation. Here, we use an ultraviolet (UV) light absorption top layer, tris(8-hydroxyquinoline) aluminum (Alq3), to improve the UV light response of poly(3-hexylthiophene-2,5-diyl) (P3HT)-based OTFTs. Unexpectedly, the Alq3-covered device operated at the accumulation mode demonstrates a decreased ID during the UV light irradiation. N,N'-Ditridecyl-3,4,9,10-perylene tetracarboxylic diimide (PTCDI, electron acceptor), pentacene (electron donor), and lithium fluoride (LiF, insulator) as an interlayer were inserted between the P3HT and the Alq3 layers. The PTCDI/Alq3-covered device also shows an unusual decrease in ID under the UV light but an increase in ID under the green light. The pentacene/Alq3-covered device shows an increased ID during the UV light irradiation and, unexpectedly, a memory effect in ID after removing the UV light. The LiF/Alq3-covered device exhibits an electrical behavior similar to the bare P3HT-based device under the UV light. Results of spectroscopic analyses and theoretical calculations have shown that the occurrence of charge transfer at heterojunctions during the UV light irradiation causes charge modulation in the multilayered P3HT-based OTFTs and then results in an unusual decrease or memory effect in ID. In addition, the unexpected ID reduction can be observed in the Alq3-covered poly[2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene]-based OTFTs under UV light. The features, including opposite electrical responses to different wavelengths of light and optical memory effect, provide the multilayered P3HT-based OTFTs with potential for various optical applications, such as image recognition devices, optical logic gates, light dosimeters, and optical synapses.

Effects of biomechanical forces on the biological behavior of cancer stem cells.

Cancer stem cells (CSCs), dynamic subsets of cancer cells, are responsible for malignant progression. The unique properties of CSCs, including self-renewal, differentiation, and malignancy, closely depend on the tumor microenvironment. Mechanical components in the microenvironment, including matrix stiffness, fluid shear stress, compression and tension stress, affect the fate of CSCs and further influence the cancer process. This paper reviews recent studies of mechanical components and CSCs, and further discusses the intrinsic correlation among them. Regulatory mechanisms of mechanical microenvironment, which act on CSCs, have great potential for clinical application and provide different perspectives to drugs and treatment design.

Association of Matrix Metalloproteinase-1 Genotypes With Bladder Cancer Risk.

AIM: There is very little literature reporting the association of matrix metalloproteinase-1 (MMP1) with personal susceptibility to bladder cancer. In the current study, we carried out the first examination of the contribution of MMP1 rs1799750 to bladder cancer risk in Taiwanese. MATERIALS AND METHODS: A total of 375 bladder cancer cases and 375 healthy controls were genotyped for MMP1 rs1799750 via polymerase chain reaction-restriction fragment length polymorphism methodology and this was evaluated for association with clinicopathological factors. RESULTS: The frequencies of MMP1 rs1799750 2G/2G, 1G/2G, and 1G/1G genotypes were 35.7%, 44.8% and 19.5% in the group with bladder cancer and 32.5%, 46.4%, and 21.1% in the healthy control group (p for trend=0.6362). The odds ratios (ORs) for bladder cancer risk after adjusting for age and gender for those carrying 1G/2G and 1G/1G genotypes at MMP1 rs1799750 were 0.88 (95% CI=0.62-1.24, p=0.4357) and 0.83 (95% CI=0.61-1.26, p=0.3990), respectively, compared with the wild-type 2G/2G genotype. In allelic frequency analysis, the adjusted OR for those carrying the 1G allele at MMP1 rs1799750 was 0.87 (95% CI=0.71-1.23, p=0.3479) compared to those people carrying a 2G allele. CONCLUSION: Our findings indicated that the genotypes at MMP1 rs1799750 appear to play little role in determining personal susceptibility to bladder cancer for Taiwanese.

The switch of DNA states filtering the extrinsic noise in the system of frequency modulation.

There is a special node, which the large noise of the upstream element may not always lead to a broad distribution of downstream elements. This node is DNA, with upstream element TF and downstream elements mRNA and proteins. By applying the stochastic simulation algorithm (SSA) on gene circuits inspired by the fim operon in Escherichia coli, we found that cells exchanged the distribution of the upstream transcription factor (TF) for the transitional frequency of DNA. Then cells do an inverse transform, which exchanges the transitional frequency of DNA for the distribution of downstream products. Due to this special feature, DNA in the system of frequency modulation is able to reset the noise. By probability generating function, we know the ranges of parameter values that grant such an interesting phenomenon.

The element of family medicine in the mega journal of the family medicine specialty: A bibliometric analysis of the journal, Chinese General Practice.

BACKGROUND: With the evolving specialization of modern medicine, family medicine (FM), also known as general practice, is relatively late in being recognized as a formal specialty in most countries of the world. Because many non-FM specialists were recruited into the new specialty in the early stages of FM specialization, the contents of FM specialty journals might, to an extent, reflect the development of the FM specialization. METHODS: In this study, the voluminous journal, Chinese General Practice, which is regarded as the most representative specialty journal, was chosen and analyzed to illustrate the current situation of FM in China. A total of 878 articles, relating to the journal, Chinese General Practice in 2018, were retrieved from the publisher's web site and the original articles were categorized into FM- and non-FM- related articles by 3 board-certified FM doctors. Furthermore, the first authors, as well as the institutions and regions where the first authors worked, and their related specialties, were also analyzed. RESULTS: Of the 634 original articles, 252 (39.7%) articles were FM related. Only 41 FM-related articles were written by authors working at FM departments: 3 at community health service centers, 29 at hospitals, and 9 at universities. Of the 382 non-FM related articles, 159 articles dealt with the topic of internal medicine, followed by traditional Chinese medicine (36), obstetrics and gynecology (28), neurology (27), pediatrics (27), and surgery (21). CONCLUSION: In conclusion, FM publications in China in the study year, as exemplified by Chinese General Practice, were mostly contributed by non-FM authors dealing with non-FM topics. A transition to more FM-oriented development might be anticipated in the near future.

Overview of the Motivation of Advance Care Planning: A Study from a Medical Center in Taiwan.

(1) Background: Since Taiwan's Patient Right to Autonomy Act took effect in 2019, up to ten thousand declarants have participated in advance care planning (ACP) and have signed advance directives (ADs). Relative to the entire population of Taiwan, only a small percentage have completed ACP. This study sought to understand the motivations of Taiwanese who have participated in ACP, so as to increase the percentage of individuals participating in ACP and signing ADs; (2) Objectives: To understand the motivations that drive Taiwanese individuals to participate in ACP discussions.; (3) Methods: A retrospective secondary data analysis was performed in this study. The participants consisted of declarants who completed their ACP at a medical center in Taiwan in 2019; (4) Results: During the study period, 946 individuals completed their ACP. Of those declarants, 66.7% were over 60 years of age; 66.5% completed the process in groups of three or more; 49.5% completed their ACP free of charge; and 35 declarants had designated a health care agent (HCA). The declarants' four main motivations for participating in ACP were "looking forward to dying with dignity," "making end-of-life preparations," "fear of being a social and economic burden on family members," and "reluctance to let family members take on the responsibility of making decisions." Furthermore, statistically significant differences were observed between the declarants in terms of gender, age, designation of an HCA, and motivations for participating in ACP. Females, declarants aged below 60 years, and declarants with a designated HCA tended to participate in ACP due to "reluctance to let family members to take on the responsibility of making decisions". Males, declarants aged above 60 years, and declarants without an HCA came for ACP because of "fear of being a social and economic burden on family members". (5) Conclusions: The main motivations of Taiwanese individuals who sought ACP were to die with dignity and to have an early understanding of end-of-life treatment and care models. Secondly, these individuals hoped that their families would not have to take on the responsibility of making decisions. They also did not want to impact their families socially and economically. In this regard, providing economic subsidies might enhance the Taiwanese public's intentions to seek ACP discussions on their own initiative.
