Combining machine learning and metaheuristics algorithms for classification method PROAFTN

© Crown 2019. The supervised learning classification algorithms are one of the most well known successful techniques for ambient assisted living environments. However the usual supervised learning classification approaches face issues that limit their application especially in dealing with the knowledge interpretation and with very large unbalanced labeled data set. To address these issues fuzzy classification method PROAFTN was proposed. PROAFTN is part of learning algorithms and enables to determine the fuzzy resemblance measures by generalizing the concordance and discordance indexes used in outranking methods. The main goal of this chapter is to show how the combined meta-heuristics with inductive learning techniques can improve performances of the PROAFTN classifier. The improved PROAFTN classifier is described and compared to well known classifiers, in terms of their learning methodology and classification accuracy. Through this chapter we have shown the ability of the metaheuristics when embedded to PROAFTN method to solve efficiency the classification problems

Productivity cost due to postpartum ill health: A cross-sectional study in Sri Lanka.

Even though postpartum morbidity continues to cause high disease burden in maternal morbidity and mortality across the globe, the literature pertaining to resultant productivity loss is scarce. Hence, the present study aimed at determining the productivity loss and associated cost of episodes of postpartum ill health.A cross sectional study was conducted in two Medical Officer of Heath areas in the Anuradhapura district, Sri Lanka in 2011, among 407 women residing in Anuradhapura district with an infant aged between 8 to 24 weeks. Validated interviewer administered questionnaires, including the IMMPACT productivity cost tool, were used to collect data on self-reported episodes of postpartum ill health. The productivity loss was calculated as the sum of days lost due to partial and total incapacitation. The adjusted productivity loss for coping strategies was calculated. Productivity cost, both total and adjusted, were calculated based on the mean daily per capita income of the study sample.Of the 407 participants, 161(39.6%) reported at least one episode of postpartum illness. Hospitalisations were reported by 27 (16.8%) of all symptomatic postpartum women. Common symptoms of postpartum ill health were pain/infection at either episiotomy or surgical site (n = 44, 27.3%), lower abdominal pain (n = 40, 24.8%) and backache (n = 27, 16.8%). The mean productivity loss per episode of ill health was 15 days (SD = 7.8 days) and the mean productivity loss per episode after adjusting for coping strategies was 7.9 days (SD = 4.4 days). The mean productivity cost per an episode was US$34.2(95$ 26.7-41.6) and the mean productivity cost per an episode after adjusting for coping strategies was US$18.0 (95$ 14.1-22.0).The prevalence of self-reported postpartum ill health, associated productivity loss and cost were high in the study sample and the main contributors were preventable conditions including pain and infection. Thus, effective pain management and proper infection prevention and control measures are important in reducing the burden of postpartum illness and resultant productivity cost

Cold type autoimmune hemolytic anemia- a rare manifestation of infectious mononucleosis; serum ferritin as an important biomarker

Abstract Background Infectious mononucleosis is one of the main manifestations of Epstein – Barr virus, which is characterized by fever, tonsillar-pharyngitis, lymphadenopathy and atypical lymphocytes. Although 60% of patients with IMN develop cold type antibodies, clinically significant hemolytic anemia with a high ferritin level is very rare and validity of serum ferritin as an important biomarker has not been used frequently. Case presentation 18-year-old girl presented with fever, malaise and sore throat with asymptomatic anemia, generalized lymphadenopathy, splenomegaly and mild hepatitis. Investigations revealed that she had cold type autoimmune hemolysis, significantly elevated serum ferritin, elevated serum lactate dehydrogenase level with serological evidence of recent Epstein Barr infection. She was managed conservatively and her hemoglobin and serum ferritin levels normalized without any intervention following two weeks of the acute infection. Conclusion Cold type autoimmune hemolytic anemia is a rare manifestation of infectious mononucleosis and serum ferritin is used very rarely as an important biomarker. Management of cold type anemia is mainly supportive and elevated serum ferritin indicates severe viral disease
