This study reports the outcomes of a collaborative program between dialysis clinics and a referral hospital, which consisted of clinical monitoring and supplementary routine surveillance, for improving the quality of vascular access care. Methods: This retrospective observational study was performed at five dialysis clinics as part of a 2-year collaborative program (2019–2020) in conjunction with a hospital-based dialysis access management center. A total of 392 hemodialysis patients (arteriovenous fistula [AVF], n = 339 and arteriovenous graft [AVG], n = 53) were included. Outcome measures included the prognosis of vascular access, clinic satisfaction, and referral rate to the hospital. Results: Increased vascular access flow was observed and critical flow events decreased from the first to the second year (AVF: 18.3% vs. 12.7%, p < 0.001; AVG: 26.2% vs. 20.1%, p = 0.30). There were fewer percutaneous transluminal angioplasty events in the AVG group (0.77 per person-year vs. 0.51 per person-year, p = 0.005). New AVF or AVG creation events also remained low. All dialysis clinics were satisfied with the program. The overall referral rate from the participating clinics increased (65.7% vs. 72.0%) during the study period independently of the physical distance between the dialysis clinic and the hospital. Conclusion: The collaboration between dialysis clinics and a referral hospital for improving the quality of vascular access care was successful in this study, and the model can be used by other clinics and hospitals looking to improve care coordination in dialysis patients.

Nevus sebaceous of Jadassohn is a congenital cutaneous hamartoma with epidermal, sebaceous, follicular, and apocrine structures that usually appears at birth or in early childhood. It has the potential to generate a variety of secondary neoplasms of different lineages, and the risk increases with patient age. Although multiple neoplasms may occasionally arise within the same lesion, the coexistence of more than five secondary tumors is extremely rare. Here we report a case of seven secondary tumors including syringocystadenoma papilliferum, desmoplastic trichilemmoma, sebaceoma, trichoblastoma, pigmented trichoblastoma, sebaceous adenoma, and tumor of follicular infundibulum arising within a nevus sebaceous. The complete diagnosis relies on the histopathological analysis of multipoint biopsies and delicate pathological sections.

Interstitial cystitis/bladder pain syndrome (IC/BPS), which is characterized by bladder pain and irritative voiding symptoms, is a frustrating disease without effective treatment. The cause is still largely not understood, although urothelium ischemia/hypoxia, apoptosis, denudation, and infiltration of inflammatory cells are common histopathological findings. The current uncertainty regarding the etiology and pathology of IC/BPS has a negative impact on its timely and successful treatment; therefore, the development of new treatment modalities is urgently needed. Herein, we present advances in our knowledge on this topic and review the potential application of regenerative medicine for the treatment of IC/BPS. This article provides information on the basic characteristics and clinical evidence of stem cells, platelet-rich plasma (PRP), and low-energy shock waves (LESWs) based on a literature review with a search strategy for articles related to IC/BPS, stem cells, PRP, and LESW published in MEDLINE and PubMed. Stem cells, PRP, and LESW, which modulate inflammatory processes and promote tissue repair, have been proven to improve bladder regeneration, relieve bladder pain, inhibit bladder inflammation, and increase bladder capacity in some preclinical studies. However, clinical studies are still in their infancy. Based on the mechanisms of action of stem cells, PRP, and LESW documented in many preclinical studies, the potential applications of regenerative medicine for the treatment of IC/BPS is an emerging frontier of interest. However, solid evidence from clinical studies remains to be obtained.

Background:
Therapeutic interventions for diabetes are most effective when administered in the newly onset phase, yet determining the exact onset moment can be elusive in practice. Spontaneous autoimmune diabetes among NOD mice appears randomly between 12 and 32 weeks of age with an incidence range from 60 to 90%. Furthermore, the disease often progresses rapidly to severe diabetes within days, resulting in a very short window of newly onset phase, that poses significant challenge in early diagnosis. Conventionally, extensive blood glucose (BG) testing is typically required on large cohorts throughout several months to conduct prospective survey. We incorporated ultrasensitive urine glucose (UG) testing into an ordinary BG survey process, initially aiming to elucidate the lag period required for excessive glucose leaking from blood to urine during diabetes progression in the mouse model.
Results:
The observations unexpectedly revealed that small amounts of glucose detected in the urine often coincide with, sometimes even a couple days prior than elevated BG is diagnosed. Accordingly, we conducted the UG-based survey protocol in another cohort that was validated to accurately identified every individual near onset, who could then be confirmed by following few BG tests to fulfill the consecutive BG + criteria. This approach required fewer than 95 BG tests, compared to over 700 tests with traditional BG survey, to diagnose all the 37–38 diabetic mice out of total 60. The average BG level at diagnosis was slightly below 350 mg/dl, lower than the approximately 400 mg/dl observed with conventional BG monitoring.
Conclusions
We demonstrated a near perfect correlation between BG + and ultrasensitive UG + results in prospective survey with no lag period detected under twice weekly of testing frequency. This led to the refined protocol based on surveying with noninvasive UG testing, allowing for the early identification of newly onset diabetic mice with only a few BG tests required per mouse. This protocol significantly reduces the need for extensive blood sampling, lancet usage, labor, and animal distress, aligning with the 3Rs principle. It presents a convenient, accurate, and animal-friendly alternative for early diabetes diagnosis, facilitating research on diagnosis, pathogenesis, prevention, and treatment.

Objective: This is a review of our cases and published literature on cheiro-oral syndrome (COS), to
better understand its localization, etiology and outcome. Methods: In addition to our database, we
reviewed the medical database (including PUBMED, BIOSIS, EMBASE, and SCOPUS) and other
sources, searched by the keyword of “cheiro-oral”. The defi nition of COS was a subjective or an
objective sensory disturbance confi ned to the perioral area and the fi nger(s)/hand without a detectable
abnormality in mental, motor or cerebellar function. Only cases of COS where the clinicoanatomic
correlation could be identifi ed by neuroimaging study, autopsy or stereotatic surgery was included.
Results: There were a total of 174 patients; 85 patients from our database, 76 patients from medical
database, and 13 patients from other sources. They were 111 men and 63 women. Their age ranged
from 12 to 85 years; average being 58.2 years. Stroke is the leading etiology and constituted 74% of
the patients. The most common location of lesion was thalamus, followed by pons and cortex. Classical
unilateral COS was seen in 81% of patients, atypical COS in 19%. Whereas the lesions were from
cortex to cervical spinal cord in unilateral COS, atypical COS was associated with lesions in pons or
medulla oblongata. An early deterioration was seen in 16.5% of patients, especially in large cortical
infarction and subdural hemorrhage. Structural lesions were found in 85% of patients.
Conclusion: Classical unilateral COS do not have a high localizing value, the atypical COS is associated
with lesion in pons or medulla.

PURPOSE: Cockroaches are the second leading allergen in Taiwan. Sensitization to Per a 2, the major American cockroach allergen, correlates with clinical severity among patients with airway allergy, but there is limited information on IgE epitopes and tissue localization of Per a 2. This study aimed to identify Per a 2 linear IgE-binding epitopes and its distribution in the body of a cockroach. METHODS: The cDNA of Per a 2 was used as a template and combined with oligonucleotide primers specific to the target areas with appropriate restriction enzyme sites. Eleven overlapping fragments of Per a 2 covering the whole allergen molecule, except 20 residues of signal peptide, were generated by PCR. Mature Per a 2 and overlapping deletion mutants were affinity-purified and assayed for IgE reactivity by immunoblotting. Three synthetic peptides comprising the B cell epitopes were evaluated by direct binding ELISA. Rabbit anti-Per a 2 antibody was used for immunohistochemistry. RESULTS: Human linear IgE-binding epitopes of Per a 2 were located at the amino acid sequences 57-86, 200-211, and 299-309. There was positive IgE binding to 10 tested Per a 2-allergic sera in 3 synthetic peptides, but none in the controls. Immunostaining revealed that Per a 2 was localized partly in the mouth and midgut of the cockroach, with the most intense staining observed in the hindgut, suggesting that the Per a 2 allergen might be excreted through the feces. CONCLUSIONS: Information on the IgE-binding epitope of Per a 2 may be used for designing more specific diagnostic and therapeutic approaches to cockroach allergy.

Psychiatry Investigation 2023;20(1):1-8
Objective:
Patients with schizophrenia are living at the border of society and their sexuality is often neglected. The aim of the study is to explore the association among The Brief Psychiatric Rating Scale (BPRS), quality of life (QoL), Taiwanese Depression Questionnaire, and Sexual Desire Inventory in people with schizophrenia (PwS).
Methods:
This study used a cross-sectional design with 277 psychiatric inpatients. A descriptive analysis, difference analysis, and logistic regression model were presented to identify relevant variables that may affect the probability of good QoL.
Results:
The study showed that male PwS had higher scores of standard deviation (SD) than females in PwS. The study also showed that smoking, early illness onset age, and shorter illness duration demonstrated a significantly higher SD. The logistic regression analysis showed that BPRS, depression, and SD significantly affected the probability of QoL. By structural equation model, SD would be positively correlated with mental status and SD would indirectly influence QoL.
Conclusion
Our results showed psychological and sociological factors interactions may contribute to the QoL and SD for PwS. This study also demonstrated a close relationship between SD, depression, and BPRS. These factors may predict the probability of good life quality for the PwS.

Numerous studies have indicated that organic fertilizers (OFer) might contain heavy metals (HMs) that present health risks to organic farmers (OFar). This study compared the concentrations of six HMs (Zn, Ni, Cd, Cu, Pb, Cr) in the blood of two distinct groups of farmers: 30 OFar from a designated organic area in eastern Taiwan, and 74 conventional farmers (CFar) from neighboring non-organic designated regions. The findings revealed that the OFar exhibited higher levels of Zn (1202.70 ± 188.74 μg/L), Cr (0.20 ± 0.09 μg/L), and Ni (2.14 ± 1.48 μg/L) in their blood compared to the CFar (988.40 ± 163.16 μg/L, 0.18 ± 0.15 μg/L, and 0.77 ± 1.23 μg/L), respectively. The disparities in Zn, Cr, and Ni levels were measured at 214.3 μg/L, 0.02 μg/L, and 1.37 μg/L, respectively. Furthermore, among the OFar, those who utilized green manures (GM) displayed significantly elevated blood levels of Zn (1279.93 ± 156.30 μg/L), Cr (0.24 ± 0.11 μg/L), and Ni (1.94 ± 1.38 μg/L) compared to individuals who exclusively employed chemical fertilizers (CFer) (975.42 ± 165.35 μg/L, 0.19 ± 0.16 μg/L, and 0.74 ± 1.20 μg/L), respectively. The differences in Zn, Cr, and Ni levels were measured at 304.51 μg/L, 0.05 μg/L, and 1.20 μg/L, respectively. As a result, OFar should be careful in choosing OFer and avoid those that may have heavy metal contamination.

PURPOSE: Many studies supported that vegetarians have a lower risk of cardiac diseases and mortality, partly due to better blood pressure and serum cholesterol profiles. However, the inflammatory markers, especially lipoprotein-associated phospholipase A2 (Lp-PLA2), have not been well-studied. This study aimed to compare inflammatory markers and conventional risk factors between vegetarians and omnivores. MATERIALS AND METHODS: One hundred and seventy-three vegetarians and 190 omnivores were studied. Fasting blood samples were obtained to compare levels of glucose, total cholesterol, triacylglycerol, high density lipoprotein (HDL) and low density lipoprotein (LDL) cholesterol, homocysteine, Lp-PLA2 activity, and high-sensitivity C-reactive protein (hs-CRP). RESULTS: Vegetarians had higher serum levels of the following markers: hs-CRP (1.8 +/- 3.4 vs. 1.2 1.8 mg/L, respectively; p = 0.05), homocysteine (9.39 +/- 3.22 vs. 7.62 +/- 2.41 micromol/L, respectively; p < 0.01), and triacylglycerol (96.91 +/- 59.56 vs. 84.66 +/- 43.24 mg/dL, respectively; p < 0.05). Vegetarians also had lower levels of Lp-PLA2 (18.32 +/- 7.19 10-3 micromol/min/mL vs. 20.22 8.13 10-3 micromol/min/mL; p < 0.05), total cholesterol (180.62 +/- 36.55 mg/dL vs. 192.73 +/- 36.57 mg/dL; p < 0.01), LDL cholesterol (118.15 +/- 32.8 vs. 126.41 +/- 34.28 mg/dL; p < 0.05), and HDL cholesterol (55.59 +/- 13.30 vs. 62.09 +/- 14.52 mg/dL, p < 0.01). Multivariate analyses demonstrated that a vegetarian diet increases the chances for high serum hs-CRP and low Lp-PLA2 activity. CONCLUSION: In addition to lower total cholesterol, LDL-cholesterol, and HDL-cholesterol, Taiwanese female vegetarians have lower serum Lp-PLA2 activity but higher levels of hs-CRP, homocysteine, and triacylglyerol. It might be due to geographic differences of vegetarian diets, and further studies are needed.
