In this study, we systematically tested the hypothesis that during the critical developmental period of adolescence, on a macro scale, the concentrations of major excitatory and inhibitory neurotransmitters (glutamate/glutamine and γ‑aminobutyric acid [GABA]) in the dorsal and ventral lateral prefrontal cortex are associated with the brain's functional connectivity and an individual's psychopathology. Neurotransmitters were measured via magnetic resonance spectroscopy while functional connectivity was measured with resting-state fMRI (n = 121). Seed-based and network-based analyses revealed associations of neurotransmitter concentrations and functional connectivities between regions/networks that are connected to prefrontal cortices via structural connections that are thought to be under dynamic development during adolescence. These regions tend to be boundary areas between functional networks. Furthermore, several connectivities were found to be associated with individual's levels of internalizing psychopathology. These findings provide insights into specific neurochemical mechanisms underlying the brain's macroscale functional organization, its development during adolescence, and its potential associations with symptoms associated with internalizing psychopathology.

BACKGROUND

Blood pressure (BP) is a vital sign that is essential in the management of hypertension, thus, there is a need for accurate measurement of BP. This will allow for proper diagnosis and management of hypertension preventing cardiovascular morbidity and mortality among Filipino patients.

METHODOLOGY

This validation study utilized the US Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) protocol for BP monitors. A total of eighty-five (85) participants had their BP measured using both the HEM 7156 and a validated aneroid sphygmomanometer. The same-sequential BP measurement was recommended to be used and a total of nine readings were collected per individual. The mean average of BP and standard deviation were extracted from the measurements. The AAMI/ESH/ISO recommends the use of certain criteria for individual BP readings (criterion 1) and individual participants (criterion 2). Appropriate statistical analysis was used for other demographic data.

RESULTS

The participants had an average age of 34 years, more than half were females, and not diagnosed with hypertension. Individuals who were diagnosed with hypertension had no other comorbidities and were on single pill only. The average arm circumference was 26.9 cm. Blood Pressure (BP) readings were adequate based on the protocol. Validity results showed that for criterion 1, systolic blood pressure (SBP) difference was 3.4 ± 7.4 mmHg, while diastolic blood pressure (DBP) was 2.0 ± 8.0 mmHg. The results for criterion 2 showed for SBP was 3.3 ± 5.3 mmHg, while DBP was 1.9 ± 6.6 mmHg. The results satisfied a passing grade on the validation protocol set by the AAMI/ESH/ISO.

CONCLUSION

This study showed that OMRON HEM 7156 is validated as a BP apparatus and may be recommended for Philippine use.

Vaginal vault prolapse occurs in 0.2% to 1.0% of menopausal women with prior hysterectomy. Even rarer is the development of concurrent rectal prolapse seen in 0.03% to 0.1% of cases. This paper aimed to 1) present a rare case of concurrent prolapses of the vaginal vault and rectum in an 87-year old grandmultipara, 2) evaluate factors predisposing to vault prolapse and rectal prolapse and their manifestations, 3) introduce the new quantitative staging system of pelvic organ prolapse by the International Continence Society, 4) discuss the options of management, and 5) emphasize the need for multidisciplinary management approach. An 87-year old grandmultipara presented with two distinct prolapsing masses at the introitus and anus. Implicated factors such as prior hysterectomy, advanced age, multiple vaginal deliveries, menopausal state and history of heavy lifting were identified. Diagnosis was made clinically. The vaginal vault prolapse was categorized quantitatively according to the Pelvic Organ Prolapse Quantification System wherein she was diagnosed to be at stage IV C. Based on such stage, treatment options, both conservative and surgical, were discussed. She underwent perineal surgery for both lesions. Effective therapy for concurrent prolapses of vaginal vault and rectum requires in-depth knowledge of pelvic anatomy and physiology, a thorough physical examination, adequate preoperative planning and prudent selection of surgical procedures that will achieve the most anatomically complete repair that will prevent recurrence.
