Background:
Amyotrophic lateral sclerosis is one of the neurodegenerative disorders with very limited
treatment options owing to its progressive course and diverse pathophysiology. Majority of
patients succumb to death within three to five years after the onset of symptoms, mostly due to
respiratory failure. This study aimed to determine the efficacy and safety of ultra-high dose
methylcobalamin versus placebo among patients with early-stage amyotrophic lateral sclerosis
in terms of slowing down functional decline.
Methods:
MEDLINE, CENTRAL, and Google Scholar databases were searched from inception up to
September 23, 2023. The impact of treatments was measured by risk ratios with 95%
confidence interval. The overall certainty of the evidence was evaluated using GRADE.
Results:
No significant difference was detected for the outcome median change in the ALSFRS-R score
for the whole cohort. Post-hoc analyses showed that ultra-high-dose methylcobalamin
decreased ALSFRS-R scores (p=0.003 for 50 mg and p=0.01 for all methylcobalamin groups) in
a dose-responsive manner. Mean difference was 1.97 in favor of methylcobalamin (95% CI,
0.44- 3.50; P = .01).
Conclusion
Ultra-high dose methylcobalamin can reduce ALSFRS-R scores of patients in its early stage but
the scarcity of clinical trials makes it difficult to support a robust conclusion. Ultra-high dose
methylcobalamin therapy remains to be investigational.

Background:
Breast cancer is the leading cause of cancer death among women worldwide. Studies showed
conflicting results regarding presence of cancer, cancer treatment, and its association with
dementia. Likewise, depression is often associated with cognitive problems.
Objectives:
This study aims to determine the prevalence and association of cognitive impairment and depression among breast cancer patients
Methods:
This is a prospective cross-sectional study utilizing Montreal Cognitive Assessment –
Philippines (MOCA-P) and Patient Health Questionnaire (PHQ-9) Filipino version
questionnaires through face-to-face interview. In analyzing the presence of cognitive
impairment and depression, Chi-square was performed; all significant factors from this test
underwent binary logistic regression to ascertain the statistical effect size for the presence of
cognitive impairment and depression.
Results:
Results showed that 80.8% (97 out of 120 patients) have cognitive impairment while 27.5% of
the patients have depression. Among the patients with cognitive impairment, 24.2% of them
had depression. Results also showed significant association between the level of education and
MOCA-P score suggesting that the higher the level of education, the better the MOCA-P score.
This study showed no significant association between presence of cognitive impairment and
depression.
Conclusion
In analyzing and managing patients with cognitive impairment, the level of educational
attainment should be put into consideration since it is correlated significantly with MOCA-P
results. As such, concomitant depression should be addressed accordingly since it may affect
the patients’ overall health status.

BACKGROUND
Type 2 Diabetes Mellitus (T2DM) patients are predisposed to cognitive decline and dementia. The cooccurrence of the two diseases translate to a higher medical cost. Identification of factors contributing to cognitive impairment is warranted.
OBJECTIVETo determine the predictors of cognitive impairment among Filipino patients with Type 2 Diabetes Mellitus.
METHODSThis is a cross-sectional analytical study involving Filipino patients diagnosed with T2DM in the outpatient clinic. A total of 171 patients were included and were screened using AD8-P tool.
RESULTSA total of 171 adult patients were included and screened for cognitive impairment.19.3% were cognitively impaired, with mean age of 59.6 years old (vs. 55.5 years old, p < 0.029), and two-thirds were female. The mean duration of the patient’s diabetes was 11.2 years. After adjusting for confounders and multi-collinearity, the duration of diabetes was significantly associated with cognitive impairment with odds of developing cognitive impairment increasing as the duration reach 10 years above. Those with T2DM for at least ten years were 2.5 times more likely to develop cognitive impairment, holding the age constant. (OR = 2.5, 95% CI – 1.0 to 5.8, p < 0.043).
CONCLUSION19.3% of Filipino patients with Type 2 Diabetes Mellitus in a tertiary government hospital are cognitively impaired and this can occur even in less than 65 years old. The ten years or longer duration of T2DM increases the risk of developing cognitive impairment by 2.5%.
