Inflammatory bowel disease (IBD) has increased in incidence and prevalence in Asian countries since the end of the 20th century. Moreover, differences in the cause, phenotypes, and natural history of IBD between the East and West have been recognized. Therefore, the Asian Organization for Crohn's and Colitis and the Asia Pacific Association of Gastroenterology have established recommendations on medical management of IBD in Asia. Initially, the committee members drafted 40 recommendations, which were then assessed according to Grading of Recommendations Assessment, Development and Evaluation. Eight statements were rejected as this indicated that consensus had not been reached. The recommendations encompass pretreatment evaluation; medical management of active IBD; medical management of IBD in remission; management of IBD during the periconception period and pregnancy; surveillance strategies for colitis-associated cancer; monitoring side effects of thiopurines and methotrexate; and infections in IBD.

Typhoid fever is an infectious disease of global importance that is caused by Salmonella enterica subsp. enterica serovar Typhi (S. Typhi). This disease causes an estimated 200,000 deaths per year and remains a serious global health threat. S. Typhi is strictly a human pathogen, and some recovered individuals become long-term carriers who continue to shed the bacteria in their faeces, thus becoming main reservoirs of infection.

Resistance in gonococci isolated in the WHO Western Pacific Region to various antimicrobials used in the treatment of gonorrhoea, 1997. WHO Western Pacific Gonococcal Antimicrobial Surveillance Programme-WHO WPR GASP

Commun. Dis. Intell., 1998 Dec 24;22(13):288-91.

PMID: 9893340

The World Health Organization Western Pacific Region Gonococcal Antimicrobial Surveillance Programme (WHO WPR GASP) is a multicentric long term programme of continuous surveillance of the antibiotic susceptibility of Neisseria gonorrhoeae. In 1997 the programme examined the susceptibility of 8,594 isolates of gonococci to various antimicrobials in 15 focal points. The trend toward increased antimicrobial resistance noted in earlier years continued. The proportion of quinolone resistant gonococci reported from most centres was either maintained or else increased. More than half of the isolates tested in China-Hong Kong, China, Japan, Korea, and the Philippines had altered quinolone susceptibility and increases in the number and percentage of quinolone resistant strains were noted in most, but not all, of the other centres. Resistance to the penicillins was again widespread, and chromosomally mediated resistance was a significant factor. Penicillinase-producing Niesseria gonorrhoeae (PPNG) were present in all centres. All isolates were sensitive to the third generation cephalosporins and only a very few isolates in China were spectinomycin resistant. High level tetracycline resistance was concentrated in a number of centres including Singapore, Malaysia, the Philippines and Vietnam. The proportion of tetracycline resistant Neiserria gonorrhoeae (TRNG) in most of the remaining centres was less than 10 per cent.

Fulltext Evaluation of WHO monoclonal antibody kit for diagnosis of acute respiratory viral infections

Khairullah NS, Lam SK

Southeast Asian J. Trop. Med. Public Health, 1995 Jun;26(2):263-7.

PMID: 8629057

In 1990 and 1991, six laboratories located in the WHO Western Pacific Region (WPR) and South East Asian Region (SEAR) were selected, based on their experience in the immunofluorescence antibody technique (IFAT), to participate in the evaluation of a WHO monoclonal antibody (Mab) kit to detect respiratory syncytial (RS) virus, influenza A virus, influenza B virus, parainfluenza virus and adenovirus. Despite differences in the initial standardization procedures, the WHO monoclonal antibodies were found to be of high quality, sensitivity and specificity when tested on clinical specimens. The constant supply of affordable high quality reagents from WHO would enable their use in clinical virological laboratories in the developing countries as well as promote the utilization of IFAT as an adjunct to cell culture isolation in the diagnosis of acute respiratory viral infections.

Differentials in urban-rural fertility in the countries of the ESCAP region

United Nations. Economic and Social Commission for Asia and the Pacific ESCAP. Secretariat

Econ Bull Asia Pac, 1985 Dec;36(2):56-80.

PMID: 12280574

Fertility differentials between rural and urban populations are investigated using World Fertility Survey data for Bangladesh, Fiji, Indonesia, Malaysia, Nepal, Pakistan, the Philippines, the Republic of Korea, Sri Lanka, and Thailand. "The fertility measure used in this analysis is the number of children ever born to a woman. An attempt is made first to establish the differential in fertility levels between urban and rural areas after necessary control of the demographic factors..., and then the possible explanation of the differential is sought in terms of socio-economic variables such as education of the respondent, and occupation, work pattern, work status and place of work of the respondent as well as that of the husband." Data concerning the fertility differentials and the associated explanatory variables are presented in tables and charts. "The results tend to show that the countries of Asia are undergoing similar patterns of fertility transition as was experienced in the advanced countries. Perhaps one can graduate the countries in the transition scale as follows: Bangladesh, Indonesia, Nepal, Pakistan and Malaysia are in the initial stage; Fiji, the Philippines, the Republic of Korea, Sri Lanka and Thailand are in the middle stage of transition."

PMID: 12340713

PIP:
This paper presents data on contraceptive prevalence from 26 national sample surveys conducted in the Asian and Pacific region during the 1966-84 period. The basic data presented are: contraceptive prevalence rates, cross-classified by age where possible; the percentage of couples using each contraceptive method, also cross-classified by age where possible. To facilitate comparison between countries and across time, the data are presented in a standardized form, both numerically and graphically. Contraceptive prevalence rates range from 1-85% (the highest and lowest ever reported). In the Asian and Pacific region as a whole, the prevalence rate was around 40%, which was about the same level as in the Latin American region. In Africa the prevalence rate was around 12%, and in developed countries around 70%. In the late 1960s, prevalence rates in the Asian and Pacific region were less than 20%. By the early 1980s, contraception had spread throughout all parts of society so that the rates in many countries were over 50%, and in some over 60%. Most of the countries with high prevalence rates were in East and Southeast Asia, and most of those with low prevalence in South Asia. Displayed graphically with the age of wife (from 15-49 years) on the x axis, contraceptive prevalence rates appear as an inverted U, low at both ends of the age range and high in the middle. Curves skewed to the left generally have stronger effects on fertility than those skewed to the right. This is due to the fact that most births occur among younger couples and contraception used by younger couples prevents more births than contraception used by older couples. The curves of countries relying primarily on sterilization are generally skewed to the right. The data show a wide variation in the mix of contraceptives used in each country. The use of various contraceptives by age is similar throughout the region. Young couples generally use oral contraceptives (OCs), those in the middle of the reproductive ages the IUD, and those near the end of the childbearing ages sterilization. Rhythm and withdrawal methods appear to be preferred both by couples in the youngest and oldest age groups. Contraceptive needs change as couples progress through the life cycle. Consequently, family planning programs must work to provide a broad mix of contraceptives. The tables show that Thailand and the Republic of Korea, 2 countries which are thought to have excellent family planning programs, have provided well-balanced mixes of contraceptives. Other countries in the region have depended on only 1 or 2 methods.

PMID: 14987061

Bioassay (P388 lymphocytic leukemia cell line and human tumor cell lines)-guided separation of the extracts prepared from the tropical and coastal trees Hernandia peltata (Malaysia) and Hernandianymphaeifolia (Republic of Maldives) led to the isolation of a new lignan designated as hernanol (1) and 12 previously known lignans: (-)-deoxypodophyllotoxin (2), deoxypicropodophyllin (3), (+)-epiaschantin (4), (+)-epieudesmin (5), praderin (6), 5'-methoxyyatein (7), podorhizol (8), deoxypodorhizone (9), bursehernin (10), kusunokinol (11), clusin (12), and (-)-maculatin (13). The oxidative cyclization (with VOF(3)) of lignans 8, 9, and 10 resulted in a new and unusual benzopyran (14), isostegane (15), and a new dibenzocyclooctadiene lactone (16), respectively. The structure and relative stereochemistry of hernanol (1) and lignans 3, 7, 8, 9, 10, 11, and 12 were determined by 1D and 2DNMR and HRMS analyses. The structures and absolute stereochemistry of structures 2, 4, 5, 6, 13, 14, 15, and 16 were unequivocally determined by single-crystal X-ray diffraction analyses. Evaluation against the murine P388 lymphocytic leukemia cell line and human tumor cell lines showed podophyllotoxin derivatives 2 and 3 to be strong cancer cell line growth inhibitors and substances 4, 5, 8, and 15 to have marginal cancer cell line inhibitory activities. Seven of the lignans and one of the synthetic modifications (14) inhibited growth of the pathogenic bacterium Neisseria gonorrhoeae.

Fulltext Aberrant Methylation of Tumour Suppressor Gene ADAM12 in Chronic Lympocytic Leukemia Patients: Application of Methylation Specific-PCR Technique

Mohamad A, Hassan R, Husin A, Johan MF, Sulong S

Asian Pac J Cancer Prev, 2021 Jan 01;22(1):85-91.

PMID: 33507683 DOI: 10.31557/APJCP.2021.22.1.85

OBJECTIVE: Chronic Lymphocytic Leukemia (CLL) is a common leukemia among Caucasians but rare in Asians population. We postulated that aberrant methylation either hypermethylation or partial methylation might be one of the silencing mechanisms that inactivates the tumour suppressor genes in CLL. This study aimed to compare the methylation status of tumour suppressor gene, ADAM12, among CLL patients and normal individuals. We also evaluated the association between methylation of ADAM12 and clinical and demographic characteristics of the participants.

METHODS: A total of 25 CLL patients and 25 normal individuals were recruited in this study. The methylation status of ADAM12 was determined using Methylation-Specific PCR (MSP); whereas, DNA sequencing method was applied for validation of the MSP results.

RESULTS: Among CLL patients, 12 (48%) were partially methylated and 13 (52%) were unmethylated. Meanwhile, 5 (20%) and 20 (80.6%) of healthy individuals were partially methylated and unmethylated, respectively. There was a statistically significant association between the status of methylation at ADAM12 and the presence of CLL (p=0.037).

CONCLUSION: The aberrant methylation of ADAM12 found in this study using MSP assay may provide new exposure to CLL that may improve the gaps involved in genetic epigenetic study in CLL.

Fulltext A/T Run Geometry of B-form DNA Is Independent of Bound Methyl-CpG Binding Domain, Cytosine Methylation and Flanking Sequence

Chia JY, Tan WS, Ng CL, Hu NJ, Foo HL, Ho KL

Sci Rep, 2016 08 09;6:31210.

PMID: 27502833 DOI: 10.1038/srep31210

DNA methylation in a CpG context can be recognised by methyl-CpG binding protein 2 (MeCP2) via its methyl-CpG binding domain (MBD). An A/T run next to a methyl-CpG maximises the binding of MeCP2 to the methylated DNA. The A/T run characteristics are reported here with an X-ray structure of MBD A140V in complex with methylated DNA. The A/T run geometry was found to be strongly stabilised by a string of conserved water molecules regardless of its flanking nucleotide sequences, DNA methylation and bound MBD. New water molecules were found to stabilise the Rett syndrome-related E137, whose carboxylate group is salt bridged to R133. A structural comparison showed no difference between the wild type and MBD A140V. However, differential scanning calorimetry showed that the melting temperature of A140V constructs in complex with methylated DNA was reduced by ~7 °C, although circular dichroism showed no changes in the secondary structure content for A140V. A band shift analysis demonstrated that the larger fragment of MeCP2 (A140V) containing the transcriptional repression domain (TRD) destabilises the DNA binding. These results suggest that the solution structure of MBD A140V may differ from the wild-type MBD although no changes in the biochemical properties of X-ray A140V were observed.

Fulltext Evaluation of PAIusp subtyping to characterize uropathogenic E. coli isolates

Lai YM, Zaw MT, Shamsudin SB, Lin Z

J Infect Dev Ctries, 2016 Oct 31;10(10):1053-1058.

PMID: 27801366 DOI: 10.3855/jidc.6944

INTRODUCTION: Uropathogenic virulence factors have been identified by comparing the prevalence of these among urinary tract isolates and environmental strains. The uropathogenic-specific protein (USP) gene is present on the pathogenicity island (PAI) of uropathogenic Escherichia coli (UPEC) and, depending on its two diverse gene types and the sequential patterns of three open reading frame units (orfUs) following it, there is a method to characterize UPEC epidemiologically called PAIusp subtyping.
METHODOLOGY: A total of 162 UPEC isolates from Sabah, Malaysia, were tested for the presence of the usp gene and the sequential patterns of three orfUs following it using polymerase chain reaction (PCR). In addition, by means of triplex PCR, the prevalence of the usp gene was compared with other two VFs of UPEC, namely alpha hemolysin (α-hly) and cytotoxic necrotizing factor (cnf-1) genes encoding two toxins.
RESULTS: The results showed that the usp gene was found in 78.40% of UPEC isolates, indicating that its prevalence was comparable to that found in a previous study in Japan. The two or three orfUs were also associated with the usp gene in this study. All the PAIusp subtypes observed in Japan were present in this study, while subtype IIa was the most common in both studies. The usp gene was observed in a higher percentage of isolates when compared with α-hly and cnf-1 genes.
CONCLUSIONS: The findings in Japan and Sabah, East Malaysia, were similar, indicating that PAIusp subtyping is applicable to the characterization of UPEC strains epidemiologically elsewhere in the world.
