In an analysis of the experiences of 10 women with chronic pain generic colospa 135mg visa muscle relaxant liquid form, Werner and Malterud (2005) sought to examine issues related to patient empowerment and how doctors can help patients deal with their difficult to diagnose symptoms order 135 mg colospa with visa spasms after gall bladder removal. The researchers 68 discussed the feelings of helplessness doctors experience when faced with patients who have conditions about which little is understood order discount colospa muscle relaxant constipation. Additionally, the authors noted that the way in which women are encountered and their symptoms addressed can have an effect on their level of empowerment in coping with their medical issues. Even in cases where diagnoses are uncertain, physicians who take women’s complaints seriously can help the patients overcome feelings of vulnerability that exacerbate their difficulties. As is the case with lupus and fibromyalgia, there are no standard diagnostic criteria and the treatments developed to date have limited success. These include placing an exaggerated importance on rest and mistakenly assuming that they are more impaired than they are. The authors drew attention to the role of gender dynamics in explaining the differences between physicians’ and patients’ perceptions of the disease. Review of Literature Related to Methodology Quantitative Research Although it can be difficult to quantify issues like gender bias and doctor-patient relationships as they pertain to chronic illness, a good deal of quantitative research literature exists on these topics. Existing quantitative studies can generally be placed into one of three common categories. The majority of quantitative studies are descriptive or correlational in nature, employing self-report surveys to measure specific variables and examining whether relationships exist between them (e. The results indicated that patient-centered approaches resulted in higher patient satisfaction with the doctor-patient relationship. In general, results from such studies are strongly conclusive and provide the clearest direction for future research. This indicates that, although survey-based quantitative studies can yield strong data, careful analysis of research design is necessary. Another common method uses survey instruments in conjunction with coding of recorded observations, such as physician visits (e. The doctors’ behaviors during the visits were coded according to a predesigned instrument and analyzed alongside data from surveys completed by both the patients and the doctors. The researchers noted that, although they found significant correlations, physicians may have behaved differently in consultations knowing that they were being recorded. This is an issue that affects studies with similar designs; findings from such studies can be difficult to interpret due to the quasi-experimental nature of recording research environments. Coded variables included those related to lifestyle advice, colon X-rays, proposed diagnoses, and others. The results showed that there existed significant gender differences in the treatment plans. Although this research design has the potential to reveal novel and unexpected aspects of the research topic, quantitatively coding and analyzing open-ended narrative data can be complicated and controversial (Hamberg et al. One of the primary strengths of quantitative research is its ability to accommodate large sample sizes. The quantitative studies reviewed for this chapter had sample sizes ranging from 30 to 387 participants. By contrast, qualitative studies reviewed had sample sizes as small as four participants. Most quantitative methods do not require researchers to spend much time with each participant, and participants can self-administer surveys simultaneously, allowing researchers to gather and analyze a large amount of data. This also allows study samples to be more diverse, contributing to the generalizability of data. The researchers synthesized a number of small studies related to gender effects in medical communication. By gathering data from smaller studies, the researchers were able to discover a broad tendency for female physicians to spend more time in communication with patients. This method allows researchers to draw more generalizable conclusions from existing data. Although quantitative studies like those reviewed above can be useful in determining general trends and providing information about the effectiveness of general practices understood broadly, quantitative research methods do not yield rich narrative data (Creswell, 2007). Qualitative research methods, on the other hand, produce the rich narrative data necessary for discovering information related to complex interactions between individuals and complex associations between illness and psychosocial factors. As mentioned previously, from a social constructionist perspective, concepts of health and illness are socially constructed and subject to varying degrees of consensus and interpretation based on cultural factors and social norms (Hearn, 2009; Lupton, 2003). In addition, patients’ interpretations of their illness influence their feelings, reactions, and behaviors (Docherty & McColl, 2003; Fernandes et al. Thus, a qualitative research approach is most appropriate for exploring the treatment experiences of women with thyroid disease. Such an understanding could prove helpful in better determining the needs of female thyroid patients and therefore lead to prompt, accurate diagnosis and effective treatment. One reason for the prevalence of qualitative methods in research related to chronic illness and therapeutic experience is the ability of qualitative studies to yield descriptive, narrative data that includes nuances and complexities of individual situations. Docherty and McColl (2003) conducted a study examining the use of narrative as a way to understand chronic illness. The study used a phenomenological methodology, eliciting descriptions of experiences from the participants and interpreting them under a social constructionist framework. The researchers identified issues that commonly arose in patients’ narrative accounts of their illness: emotional reactions to diagnoses, impact of stress, views of death, and the meaning of the illness. Such themes often do not arise in quantitative research, but can be instrumental to understanding the disease experience among people with chronic illnesses such as thyroid disease. A number of qualitative studies related to female patients’ experiences with chronic illness have been conducted (e. Qualitative methods have also been used frequently to study doctor-patient relationships and women’s healthcare experiences (e. Of the qualitative methods used in literature reviewed for this chapter, phenomenology is the most common by a wide margin. Because phenomenology is used to study individuals’ personal experiences, this is a logical choice for research related to 74 doctor-patient relationships, a topic that is closely connected with how those involved experience their interactions. Furthermore, much research related to chronic illness adopts the specific goal of understanding how patients experience illness in order to improve treatment. Within the phenomenological research reviewed, several specific approaches were used. The most common type of design employed structured, semi-structured, or open-ended interviews (Docherty & McColl, 2003; Kralik et al. Interviews allow participants to share their views about the research topic directly with researchers and allow researchers to be flexible in the specific aspects of the topic that they address, probing each participant in order to reveal complex information. Two participants were male, three were Caucasian, and they ranged in age from 29 to 74. From the interviews, the researchers identified four themes relevant to understanding the experience of people with chronic illness.

Zinc functions with cytosol superoxide dismutase inactivating free radicals; it is a free radical quencher order colospa canada spasms muscle. It is associated with the synthesis of proteins cheap 135 mg colospa with visa spasms hamstring, the stabilization of cell membranes purchase genuine colospa online muscle relaxant rx, and the function of receptor molecules. Zinc deficiency affects leukocyte functions, impairing phagocytosis; however, its impact is most marked on the specific immune system. Zinc deficiency rapidly diminishes antibody- and cell-mediated responses in both humans and animals. Zinc deficiency adversely affects lymphocyte proliferation and decreases inter- leukin-2 production by helper T lymphocytes. Glucocorticoid-mediated apoptosis induced by zinc deficiency causes downregulation of lym- phopoiesis and ensures that the lymphopenia persists. Consequently, impaired immune function resulting from dietary zinc deficiency is charac- terized in part by a reduction in the number of lymphocytes and depressed cell-mediated (i. Research suggests deficiencies of zinc and other essential nutrients such as methionine; cysteine; arginine; vitamins A, B, C, and E; and selenium promote the proliferation of Th2 cells at the expense of Th1 cells. On the other hand, adequate Zn2+ and nitrogen oxide prevents a shift of the Th1/Th2 balance toward Th2. Nitrogen oxide appears to be able to liberate Zn2+ from metallothionein, an intracellular storage molecule for metal ions. In view of the impact that zinc deficiency has on cell-mediated immunity, it is not surprising that zinc deficiency may promote cancer. Under the influ- ence of Th1 cells, zinc inhibits the growth of tumors by activating the endogenous tumor-suppressor endostatin, which inhibits angiogenesis. Furthermore, dysregulation of the Th1/Th2 balance is also believed respon- sible for autoimmune disorders such as diabetes mellitus. On the other hand, zinc supplementation may help to prevent diabetic complications through its intracellular activation of the enzyme sorbitol dehydrogenase. Animal studies suggest even a marginal zinc deficiency could affect lep- tin secretion and serum leptin concentrations. Foods stored in uncoated tin cans may reduce the amount of zinc available for absorption from that food. Absorption from lean beef is 50%, com- pared with vegetable sources or whole meal bread, in which it drops to 15%. Phosphorus-containing foods such as milk or poultry, whole grains, and fiber-rich foods impair zinc absorption. To correct zinc deficiency 220 mg three times daily (tds) plus 2 mg copper daily has been suggested. Zinc supplements are most effective if they are taken at least 1 hour before or 2 hours after meals. Assays of zinc in granulocytes and lymphocytes provide better diagnos- tic criteria for marginal zinc deficiency than plasma zinc. When used, serum zinc should be measured in the fasting state and interpreted in conjunction with albumin. Zinc deficiency, in addition to lethargy and retarded mentation, causes anorexia and reduced taste sensa- tion. However, analysis of randomized, controlled trials comparing oral zinc sulphate with placebo or no treatment in patients with arterial or venous leg ulcers concluded there was no evidence that zinc sulphate increased ulcer healing. A randomized, double-blind, placebo-controlled, clinical trial found treatment of the common cold with zinc gluconate lozenges significantly reduced the duration of cold symptoms. In fact, routine zinc supplementation may deserve consideration in certain population groups. Chronic zinc supplementation in excess of 50 mg/day can induce copper deficiency in humans. In iron- deficient animals, zinc absorption only reached a plateau at a ratio of 7. Zinc may reduce the effectiveness of therapies that rely on dopamine receptor antagonists22 and reduce absorption of penicillamine, folic acid, and tetracyclines. Thetracyclines, copper, iron, and zinc supplements should consequently be taken at least 2 hours apart to maximize the full benefit from each supplement. In humans, early evidence of zinc deficiency is anorexia, anosmia, and impaired taste (hypogeusia and dysgeusia). Dietary zinc deprivation causes brain dysfunctions such as learning impairment, enhanced susceptibility to epileptic seizures, and olfactory dysfunction. Persons with good zinc status experience a strong unpleasant taste immediately on taking a swig of the zinc tally solution. Those with a marginally adequate zinc status report a definite taste almost immediately. In contrast, moder- ately zinc-deficient persons report no specific taste after 10 seconds of hold- ing the solution in their mouth; those mildly deficient report no immediate taste, but a furry, dry mineral taste develops. Mild to moderate zinc deficiency presents with cold extremities, slow wound healing, male hypogonadism, and slow mentation. Severe zinc defi- ciency is associated with skin disorders, white spots on nails, alopecia, weight loss, psychiatric disorders, and intercurrent infection. Deficiency 758 Part Three / Dietary Supplements during growth periods results in growth failure and predisposes to congen- ital abnormalities. Acrodermatitis enteropathica, a genetic disorder, is fatal if the severe zinc deficiency is not controlled. Brighthope I: Nutritional medicine tables, J Aust Coll Nutr Env Med 17:20-5, 1998.
