Abstract
BACKGROUND & AIMS Diabetes mellitus (DM) is known to increase the risk of hepatocellular carcinoma (HCC) among individuals with chronic hepatitis C (CHC). We aimed to evaluate whether metformin reduces HCC risk among individuals with DM and CHC after successful antiviral therapy. METHODS Individuals with CHC who achieved a sustained virological response (SVR) after interferon-based therapy were enrolled in a large-scale, multicenter cohort in Taiwan (T-COACH). Cases of HCC at least 1 year after SVR were identified through linkage to the catastrophic illness and cancer registry databases. RESULTS Of 7,249 individuals with CHC enrolled in the study, 781 (10.8%) had diabetes and 647 (82.8%) were metformin users. During a median follow-up of 4.4 years, 227 patients developed new-onset HCC. The 5-year cumulative HCC incidence was 10.9% in non-metformin users and 2.6% in metformin users, compared to 3.0% in individuals without DM (adjusted hazard ratio [aHR] 2.83; 95% CI 1.57-5.08 and aHR 1.46; 95% CI 0.98-2.19, respectively). Cirrhosis was the most important factor significantly associated with higher HCC risk in Cox regression analysis, followed by DM non-metformin use, older age, male sex, and obesity; whereas hyperlipidemia with statin use was associated with a lower HCC risk. Using the two most crucial risk factors, cirrhosis and DM non-metformin use, we constructed a simple risk model that could predict HCC risk among individuals with CHC after SVR. Metformin use was shown to reduce the risk of all liver-related complications. CONCLUSIONS Metformin use greatly reduced HCC risk after successful antiviral therapy in individuals with diabetes and CHC. A simple risk stratification model comprising cirrhosis and DM non-metformin use could predict long-term outcomes in individuals with CHC after SVR. IMPACT AND IMPLICATIONS The current study provides evidence that metformin could reduce hepatocellular carcinoma (HCC) incidence after successful antiviral therapy among those with diabetes and chronic hepatitis C in a large-scale nationwide cohort study. Although successful antiviral therapy greatly reduces HCC risk in individuals with chronic hepatitis C, those with cirrhosis, diabetes, obesity, and the elderly remain at high risk of HCC development. We demonstrated that a simple risk model composed of two crucial unfavorable factors, cirrhosis and diabetes without metformin use, predicts the risk of HCC and major liver-related complications after successful antiviral therapy in individuals with chronic hepatitis C. Metformin use is highly recommended for individuals with diabetes and chronic hepatitis C after viral eradication to reduce the risk of HCC.

Abstract
Background Chronic hepatitis C (CHC) has been associated with major psychoses, and interferon (IFN)-based therapy may cause psychiatric sequelae. We aimed to evaluate the effects of sustained virological response (SVR) on the incidence of major psychoses in a nationwide Taiwanese CHC cohort. Methods Fifteen thousand eight hundred thirty-six CHC Taiwanese who received IFN-based therapy were enrolled between 2003 and 2015. Of those, 12 723 patients were linked to the National Health Insurance Research Databases for the incidence of major psychoses. Death before major psychoses was considered a competing risk. Results Twenty-four patients developed new-onset major psychoses during 67 554 person-years (3.6 per 10 000 person-years), including 16 affective psychoses, 7 schizophrenia, and 1 organic psychotic condition. The incidence of major psychoses and affective psychoses did not differ between the SVR and non-SVR groups. The 10-year cumulative incidence of schizophrenia were significantly higher in the non-SVR than in SVR patients (0.14% vs 0.04%, P = .036). Cox subdistribution hazards showed that SVR and older age were associated with a significantly lower risk of schizophrenia (hazard ratio = 0.18 and 0.17). Sustained virological response was associated with decreased incidence of schizophrenia and majorly observed among patients with age <45 (P = .02). Conclusions Successful IFN-based therapy might reduce the incidence of schizophrenia among CHC patients, especially among younger patients.

Abstract
This experiment was conducted to investigate the effects of dietary energy levels on the physiological parameters and reproductive performance of gestating first parity sows. A total of 52 F1 gilts (Yorkshire×Landrace) were allocated to 4 dietary treatments using a completely randomized design. Each treatment contained diets with 3,100, 3,200, 3,300, or 3,400 kcal of metabolizable energy (ME)/kg, and the daily energy intake of the gestating gilts in each treatment were 6,200, 6,400, 6,600, and 6,800 kcal of ME, respectively. During gestation, the body weight (p = 0.04) and weight gain (p = 0.01) of gilts linearly increased with increasing dietary energy levels. Backfat thickness was not affected at d110 of gestation by dietary treatments, but increased linearly (p = 0.05) from breeding to d 110 of gestation. There were no significant differences on the litter size or litter birth weight. During lactation, the voluntary feed intake of sows tended to decrease when the dietary energy levels increased (p = 0.08). No difference was observed in backfat thickness of the sows within treatments; increasing energy levels linearly decreased the body weight of sows (p<0.05) at d 21 of lactation and body weight gain during lactation (p<0.01). No significant differences were observed in the chemical compositions of colostrum and milk. Therefore, these results indicated that high-energy diets influenced the bodyweight and backfat thickness of sows during gestation and lactation. NRC (2012) suggested that the energy requirement of the gestation gilt should be between 6,678 and 7,932 kcal of ME/d. Similarly, our results suggested that 3,100 kcal of ME/kg is not enough to maintain the reproductive performance for gilts during gestation with 2 kg feed daily. Gilts in the treatment 3,400 kcal of ME/kg have a higher weaning number of piglets, but bodyweight and backfat loss were higher than other treatments during lactation. But bodyweight and backfat loss were higher than other treatments during lactation. Consequently, an adequate energy requirement of gestating gilts is 6,400 kcal of ME/d.

Abstract
Most foreign laborers in Taiwan come from Southeast Asia, where public health is not as well funded as in Taiwan, and parasitic infections are still common. Therefore, we recruited foreign laborers to undergo examination for parasitic infection to determine the infection conditions and follow-up conditions in foreign laborers whose stools were found to be abnormal. A total of 7,360 foreign laborers were enrolled for stool examination in our hospital, and the merthiolate iodine formaldehyde method was used to diagnose intestinal parasite infection. In total, 331 (4.5%) foreign laborers were found to be infected, and Blastocystis hominis was identified as the most prevalent intestinal parasite (2.54%), followed by Trichuris trichiura (0.54%) and hookworm (0.53%). Parasite infection rates among laborers of different nationalities were also significantly different (p < 0.001). Forty-two intestinal-parasite-infected foreign laborers received anti-parasitic therapy in our hospital, and treatment was successful. Among the 154 intestinal-parasite-infected foreign laborers who did not receive treatment in our hospital but were later re-examined, 132 were parasite-free. B. hominis has been the most prevalent intestinal parasite infecting foreign laborers in Taiwan ever since it was added to the list of infections to be screened for stool examination by the Taiwan Centers for Disease Control in 2002. It is important to closely monitor, control and treat parasite-infected foreign laborers to minimize the danger to public health.

Abstract
BACKGROUND Gallstone disease has been regarded as an obesity-related disease. Therefore, we hypothesized that leptin and adiponectin, mainly produced by adipose tissue, may play roles in gallstone disease. PATIENTS AND METHODS The RIA method was used to analyze serum leptin and adiponectin levels of 90 gallstone patients and 91 healthy subjects. RESULTS Our results showed that BMI, fasting glucose, serum AST and ALT, and leptin were significantly increased in the gallstone patients as compared with the healthy subjects (P < 0.001, P < 0.001, P < 0.001, P < 0.001, P < 0.001, and P = 0.013, respectively). Intriguingly, serum adiponectin was the only variable to be significantly decreased in the gallstone patients (P = 0.002). Furthermore, serum AST, leptin, and adiponectin were significantly associated with gallstone disease (P < 0.001, P = 0.021, and P = 0.006, respectively). Overweight (BMI >or= 25 kg m(-2)), but not normal-weight, gallstone patients had an increased serum leptin and a decreased serum adiponectin level as compared with matched healthy subjects (P < 0.001 and P = 0.024, respectively). In addition, serum leptin was positively correlated with BMI and serum cholesterol, while serum adiponectin was inversely correlated with serum triglyceride in the gallstone patients. CONCLUSIONS Our study indicated that hyperleptinaemia and hypoadiponectinaemia might be involved in the occurrence of gallstone disease. However, the causal relationship of hyperleptinaemia and hypoadiponectinaemia with gallstone disease might require further investigation.

Abstract
Filter banks, subband/wavelets, and multiresolution decompositions that employ recursive filters have been considered previously and are recognized for their efficiency in partitioning the frequency spectrum. This paper presents an analysis of a new infinite impulse response (IIR) filter bank in which these computationally efficient filters may be changed adaptively in response to the input. The new filter bank framework is presented and discussed in the context of subband image coding. In the absence of quantization errors, exact reconstruction can be achieved. By the proper choice of an adaptation scheme, it is shown that recursive linear time-varying (LTV) filter banks can yield improvement over conventional ones.

Abstract
Surgical treatment of type II odontoid fractures (OFs) has usually entailed C1-2 arthrodesis rather than fracture fixation. An alternative treatment of direct screw fixation is used to treat the fractures for preservation of atlantoaxial rotation. Type II OFs that cannot be completely reduced by close means are generally believed to be a contraindication for anterior screw fixation. Seven patients (group I) with displaced type II OFs that could be completely reduced were treated with fracture fixation by one 4.5-mm double-threaded compression screw and five patients (group II) with displaced type II OFs that could only be partially reduced were treated with fracture fixation by one 3.0-mm double-threaded compression screw. All patients had a minimum of 1-year follow-up. No major complications occurred. No loss of reduction occurred in group I patients. Group II patients had an average loss of reduction of 0.8 mm anterior displacement and 5 degrees anterior angulation. The overall rate of fracture union was 100%, and fracture resolution averaged 4.1 months. Ten patients had a normal range of cervical rotation, and there was no difference in preservation of cervical rotation between the two groups. Our results suggest that close reduction and compressive osteosynthesis by one double-threaded compression screw is an optimal method of treatment for displaced type II OFs that can be completely reduced and for some cases that can only be partially reduced. A 100% rate of fracture union and preservation of cervical rotation are the major advantages of this method. However, significant complications have been reported by other investigators.

Abstract
Cytosol from rat, mouse, and human skin or rat epidermis was incubated with [3H]arachidonic acid, [14C]retinoic acid, [14C]oleic acid, [3H]leukotriene A4, [3H]prostaglandin E2 (PGE2) or [3H] 15-hydroxyeicosatetraenoic acid (15-HETE), and protein-bound ligands were separated using Lipidex-1000 at 4 degrees C to assess the binding specificity. The binding of oleic acid and arachidonic acid with rat epidermal cytosol was rapid, saturable, and reversible. Binding of oleic acid was competed out with the simultaneous addition of other ligands and found to be in the following order: arachidonic acid greater than oleic acid greater than linoleic acid greater than lauric acid greater than leukotriene A4 greater than 15-HETE = PGE1 greater than PGE2 = PGF2. Scatchard analysis of the binding with arachidonic acid, oleic acid, and retinoic acid revealed high-affinity binding sites with the dissociation constant in the nM range. SDS-PAGE analysis of the oleic acid-bound epidermal cytosolic protein(s) revealed maximum binding at the 14.5 kDa region. The presence of the fatty acid-binding protein in epidermal cytosol and its binding to fatty acids and retinoic acid may be of significance both in the trafficking and the metabolism of fatty acids and retinoids across the skin.

Abstract
Testosterone, progesterone and cholesterol were found in mixed sexes of the nematode Trichostrongylus colubriformis from goats, according to thin-layer, gas-liquid and high-performance liquid chromatography. The structure of these steroids was confirmed by proton nuclear magnetic resonance and mass spectroscopy. Melting points of the worms' steroids were similar to authentic standards of the steroids. Estradiol was not detected in worms from either goat sex. Cholesterol was about 0.08% of the worms' dry weight in helminths from either sex of host. Testosterone was 0.02% of the dry weight when worms were taken from male goats, but only 0.005% from female goats. Progesterone was not detected in worms from male goats, but was 0.005% of the dry weight of helminths from female hosts. Incubation of a worm preparation with tritiated steroids showed that progesterone was converted to 17-alpha-hydroxyprogesterone, based on retention during radioactive thin-layer and gas-liquid chromatography, and co-crystallization. Testosterone, cholesterol and 17-beta-estradiol were not metabolized.
