Preliminary observations on the lunar and tidal influences on the catches of seer by gill nets

The paper deals with the lunar and tidal influences on the catches of seer by gill nets. The landings during full moon and new moon nights, during low and high tides and during different quarters of the lunar month for three fishing seasons are discussed.

Mesh selectivity for spotted seer, Scomberomorus guttatus (Bloch & Schneider)

An attempt has been made to evolve a suitable mesh size for the commercially significant size group of S. guttatus. To obtain maximum sustainable yield taking biological factors also into consideration, 52 mm mesh bar nets are suggested for exploiting the fishery on both the East coasts of India.

Spoilage of spotted seer (Scomberomorous guttatus) during ice storage

Quality deterioration of seer held directly in contact with ice, in different forms, fillets and chunks, and of chunks held in ice but without direct contact, was studied for a period of 15 days. While the chunks held out of contact with ice were acceptable up to 13 days based on organoleptic evaluations, the chunks and fillets held in direct contact with ice were acceptable only up to 10 days. The order of preference of the samples at any interval of ice storage was chunks held out of contact with ice>chunks held directly in ice>fillets held directly in ice. The changes in the chemical quality of these samples were also in the same order, the deterioration being maximum in fillets and least in chunks kept out of contact with ice.

Freezing characteristics of tropical fishes III. Spotted seer (Scomberomorus guttatus)

Skin-on fillets of spotted seer were frozen individually with different pre-freezing ice storage periods, and stored at -23°C and -l0°C. The frozen storage shelf life was evaluated, with respect to holding time in ice prior to freezing, by examining the extent of oxidative rancidity, protein denaturation, organoleptic changes etc. Fillets with pre-freezing ice storage periods of 0, 3, 5 and 7 days had frozen storage shelf-life of 32, 24, 20 and 16 weeks respectively at -23°C. The fillets stored in ice for more than 7 days are unsuitable for further processing. Storage temperature greatly affected keeping quality of frozen fillets. Freshly frozen fillets stored at -10°C became unpalatable at 16-20 weeks as compared to 28-32 weeks for the fillets stored at -23°C.

Common community-acquired infections and subsequent risk of multiple myeloma: a population-based study

The role of bacteria and viruses as aetiological agents in the pathogenesis of cancer has been well established for several sites, including a number of haematological malignancies. Less clear is the impact of such exposures on the subsequent development of multiple myeloma (MM). Using the population-based U.S. Surveillance Epidemiology and End Results-Medicare dataset, 15,318 elderly MM and 200,000 controls were identified to investigate the impact of 14 common community-acquired infections and risk of MM. Odds ratios (ORs) and associated 95% confidence intervals (CIs) were adjusted for sex, age and calendar year of selection. The 13-month period prior to diagnosis/selection was excluded. Risk of MM was increased by 5-39% following Medicare claims for eight of the investigated infections. Positive associations were observed for several infections including bronchitis (adjusted OR 1.14, 95% CI 1.09-1.18), sinusitis (OR 1.15, 95% CI 1.10-1.20) pneumonia (OR 1.27, 95% CI 1.21-1.33), herpes zoster (OR 1.39, 95% CI 1.29-1.49) and cystitis (OR 1.09, 95% CI 1.05-1.14). Each of these infections remained significantly elevated following the exclusion of more than 6 years of claims data. Exposure to infectious antigens may therefore play a role in the development of MM. Alternatively, the observed associations may be a manifestation of an underlying immune disturbance present several years prior to MM diagnosis and thereby part of the natural history of disease progression.

Justice in Medicare : recent changes to the public health care system

This article sets out and examines a number of changes proposed by the Commonwealth Government to the Australian Medicare system as part of the 2003-2004 and 2004-2005 federal budgets, and the 2004 federal election campaign. In assessing the suitability of these reforms, the idea of justice is discussed. Health, as a basic good, is argued to be a matter of distributional and rectificatory justice. A number of popular material principles of justice are also examined and shown to be unsuited as sole determinants of health care resource allocation decisions. In light of this, various problems with the reforms are identified and improvements suggested.

Assisted Living: The Politics of Medicaid and Medicare

In this paper I examine the structure of the current assisted living industry in order to explain how and why it is appealing and effective, as well as look at its limitations. I discuss the politics of Medicaid and Medicare, and how through these programs the federal and state governments are failing to provide adequate care for the nation’s senior population. Like the rest of our health care system, these two public health insurance systems are fragmented, and consequently, financing long-term care is complicated and insufficient. Ultimately, this paper will function as a policy report and I will propose: standardized requirements for assisted living facilities; a stricter and new way to regulate assisted living on the state level; restructured models for the public insurance programs, including Medicaid, Medicare, and the State Children’s Health Insurance Program.

Intention to claim a Medicare rebate among women receiving private Victorian pregnancy termination service

Objectives: To determine the proportion of women who have pregnancy terminations as private patients in Victoria who do not intend to claim a procedure fee rebate from Medicare, to compare characteristics of women who intend to submit a Medicare claim with those who do not and to compare the findings to the results from a similar study conducted in NSW in 1992.

Design, setting and participants: This was a cross-sectional observational study over a 12-week period. Women having a pregnancy termination service in eight large Victorian private clinics were invited to complete a brief written questionnaire.

Outcome measurer: The proportion of women who did not have a Medicare card or who had a Medicare card but did not intend to use it to claim from Medicare.

Results: Of the 1,329 women who responded, 13.1% either did not have a Medicare card or did not intend to use their card to claim a Medicare rebate. A further 20.7% of respondents were not sure about whether they would submit a claim. Women who intended to claim a Medicare rebate were different from women who did not according to age, language spoken at home, residency, citizenship and distance travelled to the service. These results are very similar to the findings from the 1992 NSW study.

Conclusion: Between 13.1% and 33.8% of private Victorian pregnancy terminations were estimated to not be recorded at the Health Insurance Commission. Health Insurance Commission records of Medicare rebate claims for pregnancy terminations are an incomplete and somewhat biased record of the services that are provided and are likely to have been so for some time.

The National Perinatal Depression Initiative: An evaluation of access to general practitioners, psychologists and psychiatrists through the Medicare Benefits Schedule

OBJECTIVE: To evaluate the impact of the National Perinatal Depression Initiative on access to Medicare services for women at risk of perinatal mental illness. METHOD: Retrospective cohort study using difference-in-difference analytical methods to quantify the impact of the National Perinatal Depression Initiative policies on Medicare Benefits Schedule mental health usage by Australian women giving birth between 2006 and 2010. A random sample of women of reproductive age enrolled in Medicare who had not given birth where used as controls. The main outcome measures were the proportions of women giving birth each month who accessed a Medicare Benefits Schedule mental health items during the perinatal period (pregnancy through to the end of the first postnatal year) before and after the introduction of the National Perinatal Depression Initiative. RESULTS: The proportion of women giving birth who accessed at least one mental health item during the perinatal period increased from 88 to 141 per 1000 between 2007 and 2010. The difference-in-difference analysis showed that while there was an overall increase in Medicare Benefits Schedule mental health item access as a result of the National Perinatal Depression Initiative, this did not reach statistical significance. However, the National Perinatal Depression Initiative was found to significantly increase access in subpopulations of women, particularly those aged under 25 and over 34 years living in major cities. CONCLUSION: In the 2 years following its introduction, the National Perinatal Depression Initiative was found to have increased access to Medicare funded mental health services in particular groups of women. However, an overall increase across all groups did not reach statistical significance. Further studies are needed to assess the impact of the National Perinatal Depression Initiative on women during childbearing years, including access to tertiary care, the cost-effectiveness of the initiative, and mental health outcomes. It is recommended that new mental health policy initiatives incorporate a planned strategic approach to evaluation, which includes sufficient follow-up to assess the impact of public health strategies.
