PTSD is associated with accelerated transcriptional aging in World Trade Center responders

Transl Psychiatry. 2021 May 24;11(1):311. doi: 10.1038/s41398-021-01437-0.

ABSTRACT

Posttraumatic stress disorder (PTSD) is associated with shortened lifespan and healthspan, which suggests accelerated aging. Emerging evidence suggests that methylation age may be accelerated in PTSD. It is important to examine whether transcriptional age is also accelerated because transcriptome is highly dynamic, associated with age-related outcomes, and may offer greater insight into the premature aging in PTSD. This study is the first reported investigation of the relationship between transcriptional age and PTSD. Using RNA-Seq data from our previous study on 324 World Trade Center responders (201 never had PTSD, 81 with current PTSD, and 42 with past PTSD), as well as a transcriptional age calculator (RNAAgeCalc) recently developed by our group, we found that responders with current PTSD, compared with responders without a PTSD diagnosis, showed accelerated transcriptional aging (p = 0.0077) after adjustment for chronological age and race. We compared our results to the epigenetic aging results computed from several epigenetic clock calculators on matching DNA methylation data. GrimAge methylation age acceleration was also associated with PTSD diagnosis (p = 0.0097), and the results remained significant after adjustment for the proportions of immune cell types. PhenoAge, Hannum, and Horvath methylation age acceleration were not reliably related to PTSD. Both epigenetic and transcriptional aging may provide biological insights into the mechanisms underpinning aging in PTSD.

Gut microbes – Early immunity and health

Med J Malaysia. 2021 May;76(3):395-400.

ABSTRACT

INTRODUCTION: Microbes in the human gut impact holistic health. Modifiable events can steer immunity through commensal microbial action. This protects from acute diseases and lays foundation for enduring health benefits. Timely modulation of immune development by correct feeding choices negate consequences of microbial dysequilibrium.

MATERIALS AND METHODS: Review and critical analysis of relevant literature integrated to the core understanding of facets of microbial existence in the gut , their roles in early immunity , and impact on health were done. Known deficiencies in newborn immunity integrated to the actions of microbes in human milk permitted some conclusions to be drawn through logical extrapolations.

RESULTS: Deficiencies in early immunity can, at least partially, be surmounted by an optimal gut microbial milieu provided for by human milk which also enhances gut immunity and holistic health.

LIMITATIONS: This is a narrative review and articles chosen were subjectively analysed for suitability according to relevance, however, analysis by statistical methods was not done.

CONCLUSIONS: There are clear pathways linking gut microbes, intestinal epithelia, microbial metabolites and early immune maturation. The immature immune system is guided towards proper development and maturation by breastmilk factors and milk microbes for immediate and enduring holistic health. Utilising this knowledge, research must be energised on possible mutualistic benefits of gut microbes to counter the current health challenges. The counselling of breastfeeding must not overlook the unique microbial environment endowed by the mother as a gift of health.

Effective connectivity between precuneus and supramarginal gyrus in healthy subjects and temporal lobe epileptic patients

Med J Malaysia. 2021 May;76(3):360-368.

ABSTRACT

INTRODUCTION: The effective connectivity (EC) when the brain is resting and how a neuronal system exerts influence over other regions of the brain, in different groups of subjects are still being investigated. Limited information was seen about the relationship between precuneus (PRE) which is a wellknown resting state hub with supramarginal gyrus (SMG) in healthy subjects (HS) and temporal lobe epilepsy (TLE) participants.

MATERIALS AND METHODS: Fourteen HS and 14 TLE patients with age and gender matched underwent resting state functional magnetic resonance imaging (rsfMRI) scanning using a 3-Tesla MRI machine to investigate the EC and percentage of amplitude fluctuation (PerAF) involving SMG and PRE. The rsfMRI data were analysed using Statistical Parametric Mapping (SPM12) and Spectral Dynamic Causal Modelling (spDCM) from which causal models were specified, estimated and inferred.

RESULTS: Model with bidirectional connections between PRE and SMG was chosen as the winning model. The EC from PRE to SMG is positive but the EC from SMG to PRE is negative in both hemispheres and in HS and TLE. Based on the findings from the EC analysis, there is an excitatory effect shown by PRE to SMG connection indicating a dominant role of PRE over SMG in both groups.

CONCLUSION: There is important evidence showing that PRE might also have influence on areas outside resting state network and the influence changes in the presence of brain abnormality.

The efficacy of intense pulse light among patients with skin type III-IV in acute facial acne: The Malaysian experience

Med J Malaysia. 2021 May;76(3):369-374.

ABSTRACT

INTRODUCTION: Twenty-seven adult patients, skin type III -V with mild to moderate acne, were recruited. IPL at wavelengths range of 420 – 600nm with triple pulses was administered every two weeks for a total of 3 sessions. Assessment of acne severity and improvement of treatment was based on Global Acne Grading System (GAGS), scoring before and after treatment for each session and patient satisfaction’s using a 5-item Likert scale range at the end of session three.

RESULTS: Of the 27 patients, 77.8% were female. Their ages group ranged from 18 to 35 years, and all patients had skin type III or IV. There were 14 mild acne patients and 13 moderate ones. There was a statistically significant improvement in mean acne severity score from 18.1± 4.3 at baseline to 14.3 ± 4.6 after two weeks post-IPL and 12.3 ± 4.9 after four weeks post-IPL. The result on satisfaction level of patients showed ‘satisfied’ in 3 patients, “very satisfied” in 5 patients; and, half of the patients (11) answered “fair” at the end of the study. Most patients tolerated well the procedure, and only 5 patients developed either post-inflammatory hyperpigmentation or skin hyperpigmentation.

CONCLUSION: The IPL of wavelength of 400-600nm offers effective, safe, and well-tolerated treatment of mild to moderate acne lesions in Malaysians with skin types III-IV. The majority of subjects had a fair score on treatment satisfaction. It is recommended that reasonable expectations for clinical results be addressed with patients before hands to prevent over-expectation.

Retention and change in PAs’ first years of employment

JAAPA. 2021 Jun 1;34(6):40-43. doi: 10.1097/01.JAA.0000750972.64581.b0.

ABSTRACT

OBJECTIVE: Employment analyses demonstrate that physician assistants (PAs) exhibit role flexibility in US medicine. The next step in understanding this labor-shifting observation is to know at what career stage it first occurs.

METHODS: Using matriculate data linked to the American Academy of PAs (AAPA) census survey data, a longitudinal analysis of seven graduate cohorts revealed that one-third of PAs changed specialty roles at least once during their first decade of employment.

RESULTS: From this series, it appears that new PAs spend about 3.4 years in their first job, on average, before they decide to move to another medical or surgical field. In examining PAs who changed their clinical role during this time period, 28% shifted from primary care to another medical or specialty role. Overall, the PA career movement to nonprimary care specialties increased substantially.

CONCLUSIONS: These findings support observations that PAs provide an adaptive role in a dynamic and changing medical workforce.

Determinants of colorectal carcinoma screening amongst patients attending a public primary care health centre in Johor Bahru

Med J Malaysia. 2021 May;76(3):346-352.

ABSTRACT

INTRODUCTION: Colorectal cancer (CRC) is one of the major causes of cancer-related mortality in Malaysia. Early screening has proven to be effective in reducing mortality due to CRC. The Malaysian CRC Clinical Practice Guidelines (2017) recommends that immunochemical faecal occult blood test (iFOBT) as the best non-invasive method for screening CRC in asymptomatic or average risk population. Outcome data on CRC screening program in the community is scarce. This study was to evaluate the prevalence and determinants of CRC among patients attending a public primary care health centre who underwent the screening program.

MATERIALS AND METHODS: Reviews of CRC Screening Registry and medical case record were conducted on patients who underwent CRC screening program at Klinik Kesihatan Mahmoodiah, Johor Bahru (KKMJB) from 2016 to 2018 period. Sociodemographic data, clinical profile of patients, iFOBT results and colonoscopy outcomes were extracted for analysis. Descriptive and inferential statistics were performed using IBM SPSS version 25.

RESULTS: Out of 591 registered patients, 584 were included for analysis. Majority of the screened individuals were males (2016-2017) compared to females (2018). Chinese were most screened individuals in 2016 [94 (46.8%)] and 2017[87 (61.7%)]. Percentage of patients with appropriate indicators for screening and underwent colonoscopy for positive iFOBT were highest recorded in 2018 (74.7%, 58.8% respectively). Prevalence of CRC among those screened with iFOBT was 1 per cent for 2017 and 2018. Adherence to annual screening with iFOBT ranged between 1.1% (2016)- 2.2% (2018). Significant association observed between gender and iFOBT results, χ2(df)= 4.747, p=0.029 (2018). Median age and ethnicity were not significantly associated with iFOBT results (p>0.05) CONCLUSION: Screening for CRC among average risk groups in primary care should focus on recruiting female patients/clients as an organised activity. Prevalence of CRC detected from screening with iFOBT was 1 per cent. CRC screening programs should focus on proportion of iFOBT positive patients progressing to receive definitive colonoscopy and complying to annual surveillance screening.

A comparison of crystal phenol treatment, midline primary closure and Limberg flap reconstruction methods in female patients with primary pilonidal sinus disease

Ann Ital Chir. 2021;92:196-200.

ABSTRACT

Pilonidal sinus disease (PSD) is a chronic problem often occurs in healthy hirsute men, however, women may also be affected. A range of conservative techniques to surgical flaps have been used to treat this condition. Currently, midline primary closure (MPC) is considered the standard of therapy; however, no statistically significant difference has been noted between primary versus secondary (Karydakis flap or Limberg flap) closure. Recently, flap reconstruction methods have been applied and superiority of these methods have been shown. Treatment methods should be employed to the individual, taking into account recurrence and complication rates of the method, recovery time, patients’ preference and surgeon’s skill. KEY WORDS: Crystal Phenol Treatment, Female Patient, Pilonidal Sinus, Limberg Flap Reconstruction, Primary Midline Closure.

A new seton tightening method for anal fistula treatment: sailor’s knot

Ann Ital Chir. 2021;92:201-205.

ABSTRACT

AIM: There are certain problems experienced while retightening the seton material during the patient follow-ups, such as pain and anaesthesia requirements in perianal fistula. The aim of the present study was to compare a sailor’s knot with other seton tightening methods for the surgical treatment of perianal fistulas.

MATERIAL AND METHODS: The records of 105 patients who underwent surgeries for perianal fistulas using the seton method between 2016 and 2019 were analysed retrospectively. The demographic characteristics, complaints, fistula localizations, surgery types, hospital stay lengths, postoperative complications and imaging modalities of the patients included in the study were recorded. The patients were divided into two groups according to the surgical treatment method. Those patients who underwent seton procedures with a sailor’s knot were included in Group 1. Group 2 included those patients who underwent other seton procedures, including silk and penrose drain procedures. Groups were compared with regard to success rates and postoperative recurrence.

RESULTS: There was no statistically significant difference between the groups in terms of the age, gender, fistula type and follow-up duration. Success rate in all patient was 88.6%, 91.2% in group 1 and 87.1% in group 2 (p=0.36). The number of patients with a kind of incontinence was 7 (7.1%), 3 (5.8%) in Group 1 and 4 (7.4%) in Group 2 (p = 0.297).

CONCLUSION: There were no statistically significant differences with regard to complications and recurrences between the sailor’s knot and the other seton tightening methods used for the treatment of anal fistulas. The sailor’s knot is recommended with regard to its easy application and seton retightening with satisfactory outcomes.

Clinical effects of different anesthesia methods in lateral episiotomy

Ann Ital Chir. 2021;92:190-195.

ABSTRACT

OBJECTIVES: To investigate the clinical effects of different anesthesia methods in lateral episiotomy. Providing the guidance of choosing the appropriate anesthesia method in clinical operation.

METHODS: A total of 300 primiparas with vaginal delivery were enrolled into this study. These primiparas were divided into three groups (n=100, each), according to the different methods of anesthesia: group A (pudendal nerve block anesthesia + stepwise dissection and incisional local anesthesia), group B (bilateral pudendal nerve block anesthesia), and group C (pudendal nerve block anesthesia + local infiltration anesthesia). The pain score of these primiparas at the time of perineal dissection and suturing, as well as suturing time and bleeding volume, were observed and compared among these three groups.

RESULTS: In respect of pain scores at the time of suturing in lateral episiotomy, maternal pain score was significantly lower in group A than in groups B and C; and the difference was statistically significant (P<0.05). In respect of the time required for suturing in lateral episiotomy, suturing time was shorter in group A than in groups B and C; and the difference was statistically significant (P<0.05). In respect of the bleeding volume in lateral episiotomy, maternal bleeding volume was lesser in group A than in groups B and C; and the difference was statistically significant (P<0.05).

CONCLUSIONS: Among these three commonly used methods of anesthesia in lateral episiotomy, the pudendal nerve block anesthesia + stepwise dissection and incisional local anesthesia method used in group A had the best analgesic effect, the shortest suturing time, and the lowest wound blood loss.
