[Proactively embracing the challenges of multimorbidity].

With rapid socio-economic development and the acceleration of population aging, the average life span of human beings has increased significantly. Individuals suffering from the co-existence of multiple diseases (multimorbidity) have become a new normal in public health and posed severe challenge to human health. Multimorbidity significantly reduces the quality of life, increases disability and mortality risks, complicates disease treatment and care and increases burden of the healthcare system with higher costs. This commentary discusses the definition of multimorbidity and common public misconceptions, then assesses its profound impact on overall public health, socio-economic development and healthcare system. We also proposes the potential strategies to meet the challenges posed by multimorbidity. The main aim is to raise awareness of multimorbidity, advocate proactive responses to improve public health and build a healthy society through the development of prevention and treatment systems and promote precision prevention and treatment for multimorbidity.

[The value of vaccines from the perspective of population medicine].

Vaccination is one of the most effective, broad-reach, and cost-effective public health initiatives to fight against infectious diseases. From the perspective of population medicine, this article systematically elaborates on the value of vaccines in preventing infections, reducing disease incidence, decreasing disability and severe cases, lowering mortality rates, improving population health and life expectancy, reducing antibiotic use and resistance, as well as promoting fairness in public health services. Based on the current situation, the following recommendations are proposed: first, strengthen scientific research to provide a solid foundation for related policy-making; second, increase the coverage rate of non-national immunization program vaccines; third, promote the inclusion of more appropriate vaccines in the national immunization program; fourth, strengthen the research and development of new vaccines; and fifth, increase talent training in the field of vaccinology.

The prevalence of HRSV in the elderly is generally higher than that in other age groups except children, which has gradually attracted attention in recent years. This paper reviewed the prevalence, common complications and major complications of HRSV in the elderly, briefly expounded the economic burden of HRSV infection, and proposed that attention should be paid to the disease burden of the elderly after HRSV infection, timely treat common complications, so as to reduce the occurrence of adverse survival outcomes and provide scientific evidence for the prevention and control of HRSV infection in the elderly.

[Research and reflection on the diversified method system of multi-stages and multi-scenarios surveillance and early warning of infectious diseases].

With the outbreak of infectious diseases, more and more attention has been paid to surveillance and early warning work. Timely and accurate monitoring data is the basis of infectious diseases prevention and control. Effective early warning methods for infectious diseases can improve the timeliness and sensitivity of early warning work. This paper briefly introduces the intelligent early warning model of infectious diseases, summarizes the emerging surveillance and early warning methods of infectious diseases, and seeks the possibility of diversified surveillance and early warning in different epidemic stages and different outbreak scenarios of infectious diseases. This paper puts forward the idea of constructing a diversified method system of infectious diseases surveillance and early warning based on multi-stages and multi-scenarios and discusses the future development trend of infectious diseases surveillance and early warning, in order to provide reference for improving the construction level of infectious diseases surveillance and early warning system in China.

[Strengthen evaluation of vaccine effectiveness to facilitate scientific and targeted prevention and control of the COVID-19 pandemic].

The COVID-19 continues to spread throughout the world, and local clusters and outbreaks related to overseas imports have occurred in many places in China. Vaccination against COVID-19 is one of the most effective tools to prevent disease, severe illness and death. For vaccines developed and used by China, it is particularly important for scientific and targeted prevention and control to study different outbreak scenarios, to conduct in-depth real-world research on SARS-CoV-2 variants, and to further promote vaccine development and technical reserves. This article commented the effectiveness of COVID-19 vaccine, and prospected the future research on vaccine efficacy, immunization strategy and vaccine development, which provided evidence for optimizing vaccination strategy.

[Research on the interaction between COVID-19 and influenza].

Since the global pandemic of COVID-19, different countries have implemented various prevention and control measures, which has affected the epidemic characteristics of respiratory infectious diseases such as influenza. From 2020 to 2021, the level of influenza activity was relatively low, but it is necessary to be alert that with the adjustment of national prevention and control measures, influenza may have a relatively strong epidemic rebound. In order to deal with influenza epidemic, experts were organized to publish a series of influenza studies in this issue, suggesting that influenza prevention and control cannot be underestimated during the COVID-19 pandemic. It is suggested to carry out research on the interaction between COVID-19 and influenza to explore the epidemic characteristics of the disease, develop new technologies and tools to improve the efficiency of monitoring and early warning, identify obstacles to vaccination, promote the scientific implementation of intervention measures, and achieve joint prevention and control of multiple diseases.

[Research progress on early warning model of influenza].

Influenza is an acute respiratory infectious disease caused by influenza virus. It usually exhibits seasonal transmission, but the novel influenza strain can lead to a pandemic with severe human health and socioeconomic consequences. Early warning of influenza epidemic is an important strategy and means for influenza prevention and control. On the basis of reviewing the main influenza surveillance and early warning systems, this study summarizes the principles, applications, advantages and disadvantages, and development prospects of common influenza early warning models, in order to provide reference for research and application of early warning technology for influenza and other acute respiratory infectious diseases.

[Application of pretrained model based on electronic medical record in recognition of acute respiratory infection].

Objective: To evaluate the recognition of acute respiratory infection (ARI) by a pretrained model based on electronic medical records (EMRs). Methods: 38 581 EMRs were obtained from Chongqing University Three Gorges Hospital in December 2021. Bidirectional encoder representation from transformers (BERT) pretrained model was used to identify ARI in EMRs. The results of medical professionals were considered as the gold standard to calculate the sensitivity, specificity, Kappa value, and area under the curve of the receiver operating characteristic (AUC). Results: There were 3 817 EMRs in the test set, with 1 200 ARIs. A total of 1 205 cases were determined as ARI by the model, with a sensitivity of 92.67% (1 112/1 200) and a specificity of 96.45% (2 524/2 617). The model identified ARI with similar accuracy in males and females (AUCs 0.95 and 0.94, respectively), and was more accurate in identifying ARI cases in those aged less than 18 than in adults 18-59 and adults 60 and older (AUCs 0.94, 0.89 and 0.94, respectively). The current model had a better identification of ARIs in outpatient patients than that in hospitalized patients, with AUCs of 0.74 and 0.95, respectively. Conclusion: The use of the BERT pretrained model based on EMRs has a good performance in the recognition of ARI cases, especially for the outpatients and juveniles. It shows a great potential to be applied to the monitoring of ARI cases in medical institutions.

Diets varying in ratio of sweet sorghum silage to corn silage for lactating dairy cows: Feed intake, milk production, blood biochemistry, ruminal fermentation, and ruminal microbial community.

The objective of this study was to investigate the effects of partial substitution of corn silage (CS) with sweet sorghum silage (SS) in the diets of lactating dairy cows on dry matter (DM) intake, milk yield and composition, blood biochemistry, and ruminal fermentation and microbial community. Thirty mid-lactation Holstein dairy cows [mean ± standard deviation; 639 ± 42.0 kg of body weight; 112 ± 24.0 d in milk (DIM)] were assigned to 3 groups (n = 10/treatment) by considering parity, milk yield, and DIM. The cows were fed ad libitum total mixed rations containing 55% forage and 45% concentrate, with only the proportion of CS and SS varying in 3 treatments (DM basis): SS0 (0% substitution of CS), 40% CS and 0% SS; SS25 (25% substitution of CS), 30% CS and 10% SS; and SS50 (50% substitution of CS), 20% CS and 20% SS. Dry matter intake and milk protein concentration tended to linearly decrease with increasing proportion of SS in the diet. Yields of milk (mean ± standard deviation, 30.9 ± 1.12 kg/d), 4% fat-corrected milk (30.0 ± 0.81 kg/d), energy-corrected milk, milk protein, lactose, and total solids, concentrations of milk fat, lactose, somatic cell counts, and milk efficiency did not differ among diets. The concentrations in blood of urea nitrogen, phosphorus, aspartate aminotransferase, and malondialdehyde linearly increased with increasing SS proportion. Blood IgA decreased with increasing SS substitution rate, but blood IgG and IgM were not different among diets. Ruminal pH did not differ among diets, whereas ruminal NH3-N concentration quadratically changed such that it was greater for SS50 than for SS0 and SS25. Molar proportions of propionate and acetate to propionate ratio were less for SS25 than for SS0. Although the diversity and general ruminal microbial community structure were not altered by partially replacing CS with SS, the relative abundances of predominant bacteria were affected by diets at the phylum and genus levels. Firmicutes and Bacteroidetes were dominant phyla in the ruminal bacterial community for all diets, and their relative abundance linearly decreased and increased, respectively, with increasing SS substitution rate. Prevotella_1 and Ruminococcaceae_NK4A214_group were detected as the most and the second most abundant genera, with their relative abundance linearly increased and decreased, respectively, with increasing SS substitution rate. The relative abundance of Fibrobacter linearly increased with increasing dietary SS proportion, with greater abundance observed for SS25 and SS50 than for SS0. These results suggest that substitution of CS with SS altered the relative abundances of some predominant bacteria; however, these changes had little effect on ruminal fermentation and milk yield. Under the current experimental conditions, substituting up to 50% of CS with SS had no negative effects on milk yield, indicating that SS can partially replace CS in the diets of high-producing lactating dairy cows without adding extra grain, when diets are fed for a short time. As the effects of substituting CS with SS depend upon the chemical composition and digestibility of these silages and the nutrient requirements of the cows, additional grain may be required in some cases to compensate for the lower starch content of SS.

[Promoting influenza vaccination during 2021-2022 season from the perspective of population medicine].

The lower temperature in autumn-winter provides favorable conditions for the survival and spread of respiratory infectious diseases such as the corona virus disease 2019 (COVID-19) and influenza. It is likely that there will be a co-circulation of respiratory pathogens such as SARS-CoV-2 and influenza. In order to promote the prevention and control of influenza and the application of influenza vaccination during the COVID-19 pandemic in China, we separately discussed the risk of influenza epidemic in the 2021-2022 season, the influenza vaccination policies, and advocate influenza vaccination during the COVID-19 pandemic from the perspective of population medicine. We appeal that COVID-19 vaccination cannot delay the normal delivery of other vaccines in the national immunization programs and non-Expanded Program on Immunization (EPI) vaccines. Promoting influenza vaccination policies and improving immunization service convenience are necessary for increasing influenza vaccine coverage, protecting public health and assisting COVID-19 response.

[Promote multidisciplinary integration, and strengthen capacities on prevention, control and pandemic preparedness of influenza].

Series of the studies and consensus on the basic research on seasonal and animal influenza virus, clinical characteristics of patients with pneumonia caused by influenza A (H1N1) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), disease burden of influenza, and promotion of influenza vaccination for the elderly were published in this special issue, aiming to describe the feature of influenza virological and clinical characteristics, health and economic burden, and vaccination. These researches emphasized the importance of the integration between basic medicine, clinical medicine, public health and preventive medicine in the prevention and control of infectious diseases. Based on the concept of population medicine, promoting the integration of multidisciplinary and strengthening prevention, control and pandemic preparedness on influenza, corona virus disease 2019 and other infectious diseases, could consolidate the foundation of surveillance and early warning, prevention and control, diagnosis and treatment of emerging infectious diseases, as well as improve the ability of emergency preparedness for public health events.

[Experience and thinking on the normalization stage of prevention and control of COVID-19 in China].

COVID-19 is an important public health issue of great concern at home and abroad, and it is still in the state of global pandemic. During the normalization stage of prevention and control of the epidemic of COVID-19, China effectively controlled the outbreak and spread of the epidemic by adopting the strategy of "import of external prevention and rebound of internal prevention", and effectively reduced the occurrence of death cases. The social economy recovered quickly, and various measures were highly recognized by the public, and the positive trend of the epidemic continued to consolidate. At present, although the spread of the local epidemic has been basically stopped, the international epidemic continues to rise rapidly, and the pressure of "imported prevention and control" in China continues to increase. Considering the characteristics of the normalization of epidemic prevention and control and the particularity of the virus, the connotation of the normalization of epidemic prevention and control should be understood scientifically. The prevention and control goal of the epidemic in the normalization stage should be to maximize early detection, early treatment and early disposal, and resolutely prevent the continuous spread of the epidemic in communities, that is, to prevent the infection as much as possible, and resolutely prevent the rebound (sustained spread in communities), rather than "zero infection". The prevention and control policy of "timely detection, rapid disposal, precise management and control, and effective treatment" has been implemented in various localities, and a series of effective and regular experience in prevention and control has been formed in the practice of prevention and control. Winter and spring are the key periods for the prevention and control of the epidemic. We should continue to work together to prevent and control the epidemic, fulfill the responsibilities of all parties, and prevent and control the epidemic in a scientific and effective way.

Feeding diets varying in forage proportion and particle length to lactating dairy cows: II. Effects on duodenal flows and intestinal digestibility of amino acids.

A study was conducted to evaluate the effects of forage-to-concentrate (F:C) ratio and forage particle length (FPL) on intake, duodenal flow, and digestibility of individual AA in the intestine of lactating dairy cows. The experiment was designed as a 4 × 4 Latin square with a 2 × 2 factorial arrangement of treatments using 4 lactating dairy cows (parity 2) with ruminal and duodenal cannulas. Low (35:65) and high (60:40) F:C ratios (dry matter basis) were combined with 2 FPL of alfalfa silage (short vs. long; 7.9 vs. 19.1 mm). Few interactions between F:C and FPL for duodenal flow and intestinal digestibility of AA occurred, but interactions were detected for intakes of several AA. Intake of essential AA and nonessential AA decreased with increasing F:C, and the intake of several individual AA increased or decreased with increasing FPL. Increasing F:C decreased duodenal flows of essential AA, nonessential AA, and microbial AA due to consistent decreased flows of most individual AA (except Glu). Degradability of most individual AA in the rumen was not affected by F:C ratio or FPL except that the degradability of His was greater with high than low F:C diets, and the degradability of Ser was greater with long versus short FPL diets. However, the degradability of individual AA within diet varied considerably. Overall, F:C ratio and FPL did not affect intestinal digestibility of AA and rumen undegradable protein AA, whereas the digestibility of individual AA in the intestine varied considerably regardless of dietary treatment. These results indicate that increasing F:C ratio decreased AA supply due to decreased flow of AA to the duodenum but altering FPL did not affect AA supply. The results also revealed the necessity to consider both the flows and digestibility of individual AA when optimizing ration formulation to meet AA requirements of dairy cows.

[Percutaneous full-endoscopic removalof lumbar dumbbell tumors viatransforaminal approach].

Objective: To investigate the novel application and effectof Percutaneous Full-Endoscopic transforaminal approach for lumbar dumbbell tumors. Methods: A retrospective analysis of 12 cases of lumbar dumbbell tumors was conducted by Percutaneous full-endoscopic transforaminal approach in the Department of Neurosurgery, Fujian Medical University Union Hospital from Feb, 2018 to Jul, 2019. According to Eden classification, 5 cases in type Ⅲ and 7 cases in type Ⅳ. The Japanese Orthopaedic Association (JOA) score and Pain Visual analogue Scale (VAS) were used to compare the recovery of neurological function before and after surgery. Results: All the 12 tumors were completely removed in one stage. The pathological reports were all schwannomas (WHO grade Ⅰ). The VAS scores were significantly decreased compared with preoperative ones (P<0.001). The JOA scores were significantly improved without obvious complications and spinal instability. Median length of follow-up was 14 months with a range of 4 months to 20 months, there is no tumor recurrence and spinal instability. Conclusion: In the treatment of lumbar dumbbell spinal tumor, the full endoscopic transforaminal approach is a novel, safe and effective surgical procedure which removes the tumors intra-foramen and extra-foramen with less damage of spine, smaller possibility of instability and faster recovery.

Effects of dietary protein levels and 2-methylbutyrate on ruminal fermentation, nutrient degradability, bacterial populations and urinary purine derivatives in Simmental steers.

The objective of this study was to evaluate the effects of dietary crude protein (CP) levels and 2-methylbutyrate (MB) supplementation on ruminal fermentation, bacterial populations, microbial enzyme activity and urinary excretion of purine derivatives (PD) in Simmental steers. Eight ruminally cannulated Simmental steers, averaging 18 months of age and 465 ± 8.6 kg of body weight (BW), were used in a replicated 4 × 4 Latin square design by a 2 × 2 factorial arrangement. Low protein (98.5 g CP/kg dry matter [LP] or high protein (128.7 g CP/kg dry matter [HP]) diets were fed with MB supplementation (0 g [MB-] or 16.8 g steer-1  day-1 [MB+]). Steers were fed a total mixed ration with dietary corn straw to concentrate ratio of 50:50 (dry matter [DM] basis). The CP × MB interaction was observed for ruminal total VFA, molar proportions of acetate and propionate, acetate to propionate ratio, ammonia-N, effective degradability of neutral detergent fibre (NDF) and CP, microbial enzyme activity, bacterial populations and total PD excretion (p < .05). Ruminal pH decreased (p < .05), but ruminal total VFA concentration increased (p < .05) with increasing dietary CP level or MB supplementation. Acetate molar proportion increased (p = .043) with MB supplementation, but was not affected by dietary CP level. Propionate molar proportion decreased (p < .05) with increasing dietary CP level or MB supplementation. Consequently, acetate-to-propionate ratio increased (p = .001) with MB supplementation, but was not affected by dietary CP level. Ruminal ammonia-N content increased (p = .034) with increasing dietary CP level, but decreased (p = .012) with MB supplementation. The effective degradability of NDF and CP increased (p < .05) with increasing dietary CP level or MB supplementation. Microbial enzyme activity, bacterial populations and total PD excretion also increased (p < .05) with increasing dietary CP level or MB supplementation. The results indicated that ruminal fermentation, nutrient degradability, microbial enzyme activity, ruminal bacterial populations and microbial protein synthesis improved with increasing dietary CP level or MB supplementation in steers.

A cross-sectional study of acute diarrhea in Pudong, Shanghai, China: prevalence, risk factors, and healthcare-seeking practices.

Diarrhea is a common cause of morbidity and mortality and the incidence of diarrhea in the world has changed little over the past four decades. To assess the prevalence of and healthcare practices for diarrhea, a cross-sectional study was conducted in Pudong, Shanghai, China. In October 2014, a total of 5324 community residents were interviewed. Respondents were asked if they had experienced diarrhea (defined as ⩾3 passages of watery, loose, bloody, or mucoid stools within a 24-h period) in the previous month prior to the interview. The monthly prevalence of diarrhea was 4·1% (95% CI: 3·3-4·8), corresponding to an incidence rate of 0·54 episodes per person-year. The proportion of individuals with diarrhea who sought healthcare was 21·2% (95% CI: 13·4-29·0). Diarrhea continues to impose a considerable burden on the community and healthcare system in Pudong. Young age and travel were identified as predictors of increased diarrhea occurrence.

Changes in the relative population size of selected ruminal bacteria following an induced episode of acidosis in beef heifers receiving viable and non-viable active dried yeast.

AIMS: To characterize the changes in the relative population size (RPS) of select ruminal bacteria and rumen fermentation variables in beef heifers supplemented with a strain of Saccharomyces cerevisiae as viable active dried (ADY) or killed dried (KDY) yeast following an induced episode of ruminal acidosis. METHODS AND RESULTS: Six ruminally cannulated beef heifers fed a diet consisting of 50% forage and 50% grain (dry matter basis) were used in a replicated 3 × 3 Latin square design with three 28-day periods. Treatments were: (i) control (CTRL; no yeast); (ii) ADY (4 g day-1 providing 1010  CFU per g; AB Vista, UK); and (iii) KDY (4 g day-1 autoclaved ADY). The acidosis challenge was induced on day 22 and rumen samples were collected on day 15 (baseline; BASE), day 22 (challenge day; CHAL), and on day 29 (168th hour post acid challenge or recovery, REC) of each period. Over the study, duration of pH <5·8 (indicative of subacute ruminal acidosis) was less for ADY and KDY than CTRL, with ADY less than KDY. No treatment effects were observed on relative abundance of ruminal bacteria, but the day effect was significant. The RPS of lactate producers and utilizers was greater while RPS of fibrolytic bacteria was lower during CHAL than BASE and REC. Yeast supplementation, irrespective of its viability, showed beneficial effects on ruminal pH variables in animals more susceptible to acidosis. CONCLUSIONS: Rumen microbial population was altered with the induction of severe acidosis. Most of the changes reverted back to baseline values during the recovery phase. Yeast supplementation reduced subacute rumen acidosis in the most susceptible cattle, but failed to attenuate severe acidosis induced by a grain challenge. SIGNIFICANCE AND IMPACT OF THE STUDY: The study provided valuable insight into the mechanism by which acidosis affects cattle performance. Individual animal variation in ruminal fermentation partly explained the variability in response to yeast supplementation in the study.

Response of lactating dairy cows to degree of steam-flaked barley grain in low-forage diets.

This study was conducted to investigate the effects of processing method (grinding vs. steam flaking) and increasing densities of steam-flaked barley grain on dry matter intake (DMI), rumen pH and fermentation characteristics, digestibility of dry matter in the total digestive tract (DDTT), and milk production of dairy cows. Eight multiparous mid-lactation Holstein cows averaging 103 ± 24 DIM, 44.5 ± 4.7 kg milk/day and weighing 611 ± 43 kg at the start of the experiment were used in a replicated 4 × 4 Latin square design with 21-day periods. Cows were fed diets consisting of (DM basis) 23.8% corn silage, 13.5% chopped alfalfa hay and 62.7% concentrate. The dietary treatments were either ground barley (GB) using a hammer mill or steam-flaked barley (SFB) - varying density at 390, 340 or 290 g/l. Processing method (GB vs. SFB) did not affect DMI (23.6 kg/day on average), DDTT (71.0% on average), milk yield (43.4 kg/day on average), milk components, rumen pH and molar proportions of acetate, propionate, butyrate and sorting activity. Ruminal isovalerate concentration tended (p = 0.06) to be higher for cows fed GB than those fed SFB-based diets. Decreasing the density of SFB from 390, 340 to 290 g/l tended to linearly increase DMI (p = 0.09), decrease total solids percentage of milk (p = 0.10) and linearly decreased milk urea nitrogen (12.8, 12.4 and 12.1 mg/dl; p = 0.04); also, the sorting index (SI) of the particles retained on the 19.0-mm sieve without affecting the SI of the particles retained on 8.0-mm, 1.18-mm or passed through 1.18-mm sieve (p = 0.05). These results indicated the limited effects of processing method (grinding vs. steam flaking) and densities of SFB (390, 290 or 290 g/l) on cows' performance and feed utilization for dairy cows fed low-forage diets. Therefore, both processing methods could be recommended under current feeding conditions of dairy cows.

[Analysis on funds application of community based organizations involved in HIV/AIDS response and government financial investment in China, 2014].

Objective: To understand the government financial investments to community based organizations (CBO) involved in HIV/AIDS Control and Prevention of China and its influencing factors. Methods: Questionnaire of the situation of CBO involved in HIV/AIDS control and prevention were designed, and filled by the staff of Provincial Health Administrative Departments of 31 provinces (autonomous regions and municipalities). The research focused on the fields of CBO involved in HIV/AIDS response in 31 provinces (autonomous regions and municipalities), including intervention on HIV/AIDS high risk population (female sex worker (FSW), man who sex with man (MSM), drug user (DU) and case management and care for people living with HIV/AIDS (PLWH)). 29 valid questionnaires were collecting, with Shanxi Province and Inner Mongolia Autonomous Regions not filled. Questionnaire included financial supports from local governments, transfer payment from central government for CBO involved in HIV/AIDS response in 2014, and unit cost for CBO involved in HIV/AIDS control and prevention. Multivariate analysis was conducted on the project application and financial investment of community based organizations involved in HIV/AIDS control and prevention in 2014. Results: The total amount of CBO to apply for participation in AIDS prevention and control was 64 482 828 Yuan in 2014. The actual total amount of investment was 50 616 367 Yuan, The investment came from the central government funding, the provincial level government funding, the prefecture and county level government funding investment and other sources of funding. 22 of 28 provinces (autonomous regions and municipalities) received the funds from the central government finance, and median of investment funds 500 000 Yuan. 15 provinces (autonomous regions and municipalities) gained the funds from the provincial government finance, and median of investment funds 350 000 Yuan. 12 provinces (autonomous regions and municipalities) got the funds from the prefecture and county level government finance, and median of investment funds 408 750 Yuan. 12 provinces (autonomous regions and municipalities) acquired the funds from other sources, and median of investment funds 228 400 Yuan. The median (P(25), P(75)) unit costs of intervention for FSW from 16 provinces (autonomous regions and municipalities) was 70 (23, 280) Yuan per year; DU from 14 provinces (autonomous regions and municipalities) was 83 (44, 200 ) Yuan per year; MSM from 16 provinces (autonomous regions and municipalities) was 100 (35, 280) Yuan per year; the follow-up and care for PLWH from 17 provinces (autonomous regions and municipalities) was 200 (45, 500) Yuan per year. Multivariate linear regression analysis results showed that the amount of PLWH in 2014 influenced on the total number of application funds of CBO involved in HIV/AIDS response (b=178.11, 95% CI: 51.86-305.36) and the amount of PLWH (b=77.72, 95% CI: 16.28-139.16), and Gross Domestic Product (GDP) per capita of the province (b=36.20, 95% CI: 4.60-67.80) impacted financial investment to CBO involved in HIV/AIDS response, respectively. Conclusion: Funds application and financial investment of CBO involved in HIV/AIDS control and prevention were huge. Financial investment from government was main resources for CBO in 2014. The amount of financial investment funds from governments was influenced by the HIV/AIDS epidemic situation and the development level of local economic.

The effects of increasing garlic powder and monensin supplementation on feed intake, nutrient digestibility, growth performance and blood parameters of growing calves.

The objective of this study was to evaluate the effects of increasing garlic powder and monensin supplementation on feed intake, nutrient digestibility, growth performance and blood metabolites of growing calves. Forty Holstein calves (BW = 100 ± 11 kg) were randomly assigned to four dietary treatments (n = 10) in a complete randomized design. Experimental treatments consisted of the following: (i) basal diet (control), (ii) basal diet supplemented with 0.0003% of dietary dry matter (DM) sodium monensin, (iii) low level of garlic powder (Low-GAR; 0.5% of dietary DM) and (iv) high level of garlic powder (High-GAR; 1% of dietary DM). DM intake (DMI) and DM digestibility were (p < 0.05) decreased by High-GAR. However, calves supplemented with Low-GAR had a similar DMI to the control calves and similar DM digestibility to the control and monensin groups. The digestibility of other nutrients were not affected by the treatments. Although supplementing monensin relative to Low-GAR increased the DMI (p < 0.05), average daily gain was similar between Low-GAR and monensin supplemented calves, which were higher than the control and High-GAR groups (p < 0.05). As a result, feed conversion ratio was improved in the Low-GAR group versus other treatment groups (p < 0.05). Administrating garlic powder decreased the blood low-density lipoprotein (LDL) and non-esterified fatty acids (p < 0.05) without affecting the blood triglyceride, high-density lipoprotein and beta-hydroxybutyric acid concentrations. In conclusion, the calves fed the Low-GAR showed an improved FCR and blood metabolites without changing the DMI and nutrient digestibility. It suggests that garlic powder could be used as an alternative to monensin for growing calves under the current feeding conditions.
