Background and ObjectiveCervical cancer is one of the leading causes of morbidity and mortality amongst the gynecological cancers worldwide, especially in developing countries. It is imperative for at least health professionals in developing countries like Pakistan to have a sound knowledge about the disease. This study was carried out to assess the knowledge and awareness about cervical cancer and its prevention amongst health professionals in tertiary care hospitals in Karachi, Pakistan.Methods and DesignA cross-sectional, interview based survey was conducted in June, 2009. Sample of 400 was divided between the three tertiary care centers. Convenience sampling was applied as no definitive data was available regarding the number of registered interns and nurses at each center.ResultsOf all the interviews conducted, 1.8% did not know cervical cancer as a disease. Only 23.3% of the respondents were aware that cervical cancer is the most common cause of gynecological cancers and 26% knew it is second in rank in mortality. Seventy-eight percent were aware that infection is the most common cause of cervical cancer, of these 62% said that virus is the cause and 61% of the respondents knew that the virus is Human Papilloma Virus (HPV). Majority recognized that it is sexually transmitted but only a minority (41%) knew that it can be detected by PCR. Only 26% of the study population was aware of one or more risk factors. Thirty seven percent recognized Pap smear as a screening test. In total only 37 out of 400 respondents were aware of the HPV vaccine.ConclusionThis study serves to highlight that the majority of working health professionals are not adequately equipped with knowledge concerning cervical cancer. Continuing Medical Education program should be started at the hospital level along with conferences to spread knowledge about this disease.

A shared understanding of medical conditions between patients and their health care providers may improve self-care and outcomes. In this study, the concordance between responses to a medical history self-report (MHSR) form and the corresponding provider documentation in electronic health records (EHRs) of 19 select co-morbidities and habits in 230 patients with heart failure were evaluated. Overall concordance was assessed using the κ statistic, and crude, positive, and negative agreement were determined for each condition. Concordance between MHSR and EHR varied widely for cardiovascular conditions (κ = 0.37 to 0.96), noncardiovascular conditions (κ = 0.06 to 1.00), and habits (κ = 0.26 to 0.69). Less than 80% crude agreement was seen for history of arrhythmias (72%), dyslipidemia (74%), and hypertension (79%) among cardiovascular conditions and lung disease (70%) and peripheral arterial disease (78%) for noncardiovascular conditions. Perfect agreement was observed for only 1 of the 19 conditions (human immunodeficiency virus status). Negative agreement >80% was more frequent than >80% positive agreement for a condition (15 of 19 [79%] vs 8 of 19 [42%], respectively, p = 0.02). Only 20% of patients had concordant MSHRs and EHRs for all 7 cardiovascular conditions; in 40% of patients, concordance was observed for ≤5 conditions. For noncardiovascular conditions, only 28% of MSHR-EHR pairs agreed for all 9 conditions; 37% agreed for ≤7 conditions. Cumulatively, 39% of the pairs matched for ≤15 of 19 conditions. In conclusion, there is significant variation in the perceptions of patients with heart failure compared to providers’ records of co-morbidities and habits. The root causes of this variation and its impact on outcomes need further study.

Subclinical hypothyroidism is defined by an elevated serum thyroid-stimulating hormone (TSH) level along with a normal free thyroxine (T 4 ) level. Whether it should be treated remains controversial. Currently, the best practical approach is to base treatment decisions on the degree of TSH elevation, thyroid autoimmunity, and associated comorbidities. KEY POINTSFrom 4% to 20% of adults have subclinical hypothyroidism, with a higher prevalence in women, older people, and those with thyroid autoimmunity.Subclinical hypothyroidism can progress to overt hypothyroidism, especially if antithyroid antibodies are present, and has been associated with adverse metabolic, cardiovascular, reproductive, maternal-fetal, neuromuscular, and cognitive abnormalities and lower quality of life.Some studies have suggested that levothyroxine therapy is beneficial, but others have not, possibly owing to variability in study designs, sample sizes, and patient populations.Further trials are needed to clearly demonstrate the clinical impact of subclinical hypothyroidism and the effect of levothyroxine therapy.Dr. Nasr has disclosed teaching and speaking for Eisai, Genzyme/Sanofi, and Shire and membership on an advisory committee or review panel for Exelixis, Nevro, and Pfenex.

Type 2 diabetes increases the risk of developing cardiovascular (CV) complications such as myocardial infarction, heart failure, stroke, peripheral vascular disease, and CV-associated mortality. Strict glycemic control in diabetics has shown improvement in microvascular complications related to diabetes but has been unable to demonstrate major effects on macrovascular complications including myocardial infarction and stroke. Conventional therapies for diabetes that include insulin, metformin, sulfonylureas (SU), and alpha-glucosidase inhibitors have limited and/or controversial data on CV safety based on observational studies not designed or powered to assess CV safety of these medications. In 2008, the US Food and Drug Administration (FDA) revised regulations for the approval of medications for type 2 diabetes by requiring that enough CV events are accrued prior to approval to rule out an upper 95 % confidence interval (95 % CI) for HR of 1.8 for CV events, followed by ruling out an upper 95 % CI for HR of 1.3 in the post-approval period. To date, novel diabetes therapies including peroxisome proliferator-activated receptor (PPAR) gamma agonists, dipeptidyl peptidase-4 (DPP4) inhibitors, glucagon-like peptide 1 (GLP 1) analogs, and sodium-glucose transporter-2 (SGL2) inhibitors have been evaluated in CV safety trials. Results from the first major CV outcome studies in type 2 diabetes, SAVOR-TIMI 53 and EXAMINE, have shown that neither saxagliptin nor alogliptin had increases in major CV events relative to placebo in high-risk patients. Ongoing and future trials will elucidate the CV safety for other DPP-4 inhibitors compared to SUs and the GLP-1 agonists versus placebo.
