HIV/AIDS: The Past, Present and Future

                         http://www.mathewsopenaccess.com/hiv-aids-current-issue.html

Human immune deficiency virus (HIV) is closely related to the simian immunodeficiency virus which is found in monkeys and apes. HIV-I is closely related to the strains of SIV found in chimpanzees, and HIV-II is closely related to the strains of SIV found in the sooty mangabeys. In 1999 some scientists found a strain of SIV ( called SIVcpz) in chimpanzees that was closely related to HIV-I in humans. It was then concluded that this proved that chimpanzees were the source of HIV-I and had crossed species to humans at some point in time. Furthermore it was thought that these chimpanzees got the SIV virus by eating two smaller monkeys (red-capped mangabeys and greater spot nosed monkeys) and became infected with two strains of SIV. These two strains joined together to form the SIVcpz strain which has the ability to infect humans. This was followed by the concept of the hunter who ate these chimpanzees and became infected or the viruses were able to access the hunter through wounds and cuts. Ocassionally the hunter would be able to ‘fight’ off this SIV, but sometimes they were able to survive in humans as HIV. 

HIV-II comes from SIVsmm in sooty mangabey monkeys rather than chimpanzees. The crossover to humans is believed to have happened in a similar way (through the killing and consumption of monkey meat). It is far rarer, and less infectious than HIV-1. As a result, it infects far fewer people, and is mainly found in a few countries in West Africa like Mali, Mauritania, Nigeria and Sierra Leone. There are four groups of HIV strains M,N,O,P with M being the most common with nine subtypes (A-D,F-H,J,K). There are so many strains because in the attempt to enter and adapt to survive within the human system the SIV had to evolve into several strains the most successful being able to survive the new environment.

Researchers have come to the conclusion that this “zoonotic” infection of humans with this virus started around 1920 in the Democratic Republic of Congo. The same area is known for having the most genetic diversity in HIV strains than anywhere else, reflecting the number of different times SIV was passed to humans. Many of the first cases of AIDS were recorded there too. The extensive transport routes in that part including the railways, rivers and road networks together with the high migrant population and growing sex trade all supported the spread of the HIV virus. The lack of transport routes in the north and east of the country accounted for the lower reports of infections from these regions at the time. By 1980, half of all infections in DR Congo were in locations outside of the Kinshasa area, reflecting the growing epidemic. 

Bilateral Stress Fractures of Pubic Ramus in a Patient affected by Hyperparathyroidism

                                                         www.mathewsopenaccess.com

This case report presents a 48-year-old patient who was diagnosed of bilateral pubic ramus stres fracture in one year period. She was admitted with hip and groin pain. In our case, direct radiography followed by MRI was used for diagnosis. Hyperparathyroidism was detected as a etiological cause. Patient underwent conservative treatment for bilateral stres fractures of pubic ramus with perfect results. Attending to this case report, in patients with non-traumatic groin pain and endocrinological disorders, pubic ramus stress fracture is a diagnosis that should be kept in mind.

Stress fractures are those that occur in a local area of a normal or pathologic bone, due to less powerful forces that will normally result in a complete fracture. This kind of fractures are divided into three different subgroups: fatigue fracture, insufficiency fracture, and pathologic fracture. Fatigue fractures occur in healthy bones due to unusual mechanical effect. Their prevalency is increased in young adults, especially in weight bearing bones. Attending to the risk factors, fatigue fractures are most frequenly observed in athletes, dancers, and soldiers. On the other hand, insufficiency fractures occurs as a result of reduced bone resistance under normal bearing. Many clinical risk factors have been identified with this fracture type, including osteoporosis, osteomalacia, hyperparathyroidism, rheumatoid arthritis, long term use of cortisone, diabetes mellitus, fibrous dysplasia, renal insufficiency, and radiotherapy.

Attending to insufficiency fractures, most pelvic insufficiency fractures occur in women, particularly those with osteoporotic bone. They represent, approximately, 1-2% of all the stress fractures, and they most commonly observed at the pubic ramus. This kind of fractures are usually asymptomatic; nevertheless, these patients ay present groin and back pain. For our knowledge, bilateral pubic ramus stress fracture due to hyperparathyroidism has not been reported previously. In this case report, we present a case report of a female patient affected of this type of fracture and realize a short review about of stress fractures in patients affected of endocrinological mineral balance disorders, including hyperparathyroidism. 

Pregnancy Outcomes Upon Using Arabin Pessary in Cases of Premature Cervical Shortening

                                                        www.mathewsopenaccess.com

Spontaneous preterm birth is the leading cause of perinatal morbidity and mortality. Several methods were found to be helpful in preventing preterm deliveries in singleton gestations. Those include progesterone administration and different cervical cerclage. Arabin Pessary which is a silicone made device has been explored in recent years as a method of preterm birth prevention. In contrast to singleton gestations, neither progesterone administration nor cervical cerclage were found to be affective in a multi-gestational pregnancy. Our article describes three cases with increased chances of preterm delivery. Two singletons and one multi-gestational pregnancy. All three women received a cervical Arabin Pessary in addition to the accepted treatment of progesterone. All three women had favorable results and delivered healthy infants. We concluded from our experience and from trials conducted in centers around the world that cervical Arabin Pessary is beneficial in preventing preterm birth both in singleton and in multi-gestational pregnancies.

A 40 year old gravida 5 para 1, turned up for a medical evaluation 23+6 weeks gestation after in vitro fertilization [IVF] due to lower abdominal pressure. Primary evaluation determined 20 millimeters cervical length with a U shaped funneling. Her history included a genetic screening which demonstrated 2% 45 x0, 4% 47xxx and 94% 46 xx genetic mosaicism. During her previous pregnancy she experienced cervical shortening at 16 weeks gestation. McDonald’s cerclage was administered. At 25 weeks gestation cesarean section was performed after she experienced septic shock and the cerclage was removed. Her first trimester genetic screening determined a 1:95 chance for down’s syndrome. Second trimester genetic screening determined a 1:170 chance for down’s syndrome. She refused to go throw amniocentesis. 200 mg of Uterogestan®( Laboratoires Besins International) was given once daily and Arabin Pessary was inserted upon the cervix. During her admission period she was diagnosed with gestational diabetes mellitus which was well controlled with a low carbohydrate diet was discharged at 27 weeks gestation and returned to labor and delivery in active labor 36+4 weeks gestation. She delivered vaginally. The fetus weighed 2400 gram and received Apgar scores of 9 and 10 after 1 and 5 minutes.

A 25 year old gravida 1 para 0 bichorionic biamniotic twin pregnancy after intrauterine insemination[IUI] turned for a medical evaluation 25 weeks gestation due to uterine contractions. Her medical history is within normal limits and so does her first and second trimester genetic screenings. Her cervical length was 23 mm dilated to 3 cm [figure 1]. In addition, the amniotic sac was exposed at the external cervical os. Her Monitor exhibited recurrent contractions. After Atosiban®[Ferring] administration contractions have subsided. She received magnesium for neuroprotection and Celestone. Arabin pessary was installed upon the cervix . 

A Brief Overview of Post-Partum Obsessive Compulsive Disorder

        http://www.mathewsopenaccess.com/PDF/Gynecology/M_J_Gyne_1_1_006.pdf

General postpartum mood disorders, specifically depression and anxiety, have been well studied in the literature. However, there is limited data regarding the identification, diagnosis, and management of postpartum obsessive compulsive disorder (ppOCD). Women with this diagnosis are frequently undiagnosed or misdiagnosed and, regretfully, suffer with their symptomatology. The purpose of this review is to educate the clinician on the prevalence and signs and symptoms of ppOCD, and to offer recommendations regarding the pharmacologic and psychotherapeutic management of this disorder.

Postpartum OCD is thought to occur in approximately 1-5% of all postpartum mothers. Pregnant and postpartum women are more likely to experience OCD compared to the general population. Risk factors include a personal history of anxiety disorders and/or OCD, personal history of depression (El-Mallakh or a family history of anxiety or depression. The onset of symptoms may occur rapidly, within a week of delivery. Interestingly, the focus of the obsessions and compulsions are similar between mothers. Aggressive obsessive thoughts involving the baby are significantly more common in groups of women with postpartum depression. Due to the disturbing obsessive thoughts that mothers have, many fear telling their physician or families for concern that their child will be taken from them, resulting in non-identification and non-treatment of their disorder.

As part of a routine postpartum follow up exam, the Edinburgh Postnatal Depression Scale (EPDS) is recommended for evaluating women for postpartum depression. This scale includes 10 questions which are completed by the patient and scored by the provider. Within this scale, some questions (#4- 6) focus on anxiety symptoms. If and when women have elevated scores on this section, it is worthwhile to further investigate for anxiety disorders, including ppOCD. Although there is no specific screening tool for ppOCD, the Florida Obsessive Compulsive Index (FOCI) is one example of a screening tool that can be given to the postpartum patient for completion. Scores of 8 or higher on this scale are highly suggestive of OCD. For providers that may not have access to the EPDS or FOCI, simply asking the woman if she finds herself having repetitive thoughts or avoiding certain things or behaviors may give the clinician additional information and evidence for a diagnosis of ppOCD. This should lead the clinician to further investigate the symptoms and determine whether they need additional evaluation by the clinician or referral to a psychiatrist. 

More Folic Acid in Pregnancy May Protect Kids From High Blood Pressure

                                                          www.mathewsopenaccess.com

Higher folic corrosive levels amid pregnancy may diminish the danger of hypertension in kids if their moms have coronary illness hazard considers, another review suggests."Our think about includes additional proof the early life starting points of hypertension," said senior relating creator Dr. Xiaobin Wang, a pediatrician from Boston University. "Our discoveries raise the likelihood that early hazard evaluation and intercession before origination and amid pregnancy may prompt to better approaches to avoid hypertension and its outcomes crosswise over life expectancy and eras," Wang said in a diary news discharge. 

She and her exploration partners took a gander at information from right around 1,300 mother-youngster sets from births at Boston Medical Center. The mothers and children were taken after from 2003 to 2014. 66% of this gathering were dark, and about 20 percent were Hispanic.The scientists needed to check whether a lady's folic corrosive levels and coronary illness chance components - including hypertension, diabetes and heftiness amid pregnancy independently and mutually affected a kid's blood pressure.Nearly 29 percent of the kids had hoisted systolic pulse from ages 3 to 9 years. Systolic pulse is the top number in a circulatory strain perusing. Kids with higher pulse will probably have moms with pre-pregnancy weight, hypertension and diabetes. 

Those youngsters were additionally more prone to have bring down birth weight, bring down gestational age and a higher body mass list (BMI - a gauge of muscle to fat quotients in light of tallness and weight). More elevated amounts of folic corrosive amid pregnancy were related with a 40 percent bring down danger of hypertension among offspring of moms with coronary illness chance variables. 

Notwithstanding, a mother's folic corrosive levels alone were not connected with a youngster's pulse. She needed to likewise have coronary illness chance elements for folic corrosive to have any kind of effect, the review found.

Have Americans Given Up on Losing Weight?

                                                      mathewsopenaccess.com

Americans are overweight or fat, however many have abandoned attempting to lose those overabundance pounds, another review appears. 

One in each three individuals in the United States is presently corpulent, contrasted and one in five 20 years prior, scientists report. 

In any case, individuals overviewed in the vicinity of 2009 and 2014 were 17 percent more outlandish generally speaking to state they'd attempted to get more fit amid the earlier year than those reviewed in the vicinity of 1988 and 1994, the review found. 

Individuals who were overweight however not yet fat have encountered the best loss of enthusiasm for keeping up a solid weight, said senior specialist Dr. Jian Zhang. 

"This is bad. We are feeling the loss of the chance to prevent overweight from getting to be weight," said Zhang, who is a connect teacher of the study of disease transmission with Georgia Southern University. 

Zhang and his associates dissected information from the U.S. National Health and Nutrition Examination Survey, a governmentally subsidized continuous study that monitors Americans' wellbeing and eating routine propensities. 

All racial/ethnic gatherings crosswise over both sexual orientations detailed diminished enthusiasm for weight loos,but ladies specifically will probably say they'd abandoned it, the discoveries appeared. 

By 2014, dark ladies were 31 percent less inclined to have attempted to get more fit contrasted and two decades earlier, and white ladies were 27 percent less inclined to have made the endeavor, the specialists found. 

Individuals may abandon weight reduction since it's recently excessively troublesome, Zhang said. 

"It's excruciating," he clarified. "It's difficult to drop pounds. A significant number of us attempted and fizzled, attempted and fizzled, lastly neglected to attempt any longer." 

Current drug additionally has become better at safeguarding the general wellbeing of overweight individuals, maybe making them inquire as to why they ought to trouble, Zhang proceeded.

New Nasal Spray, Noctiva, Reduces Nighttime Urination

                                                                http://www.mathewsopenaccess.com/

A nasal shower definition of desmopressin acetic acid derivation, successful at lessening the quantity of times grown-ups need to urinate amid the night, has been endorsed by the U.S. Sustenance and Drug Administration. 

Noctiva (desmopressin acetic acid derivation) is a nasal splash for grown-ups who make no less than two evening treks to the washroom because of causes, for example, certain prescriptions, perpetual heart disappointment inadequately controlled diabets and bladder and prostate issues, the Associated Press reported.The shower, utilized around 30 minutes before sleep time every night, helps the kidneys ingest more water keeping in mind the end goal to diminish the measure of pee. 

Noctiva conveys a discovery cautioning - the FDA's most grounded - about the danger of hazardously low levels of sodium in the blood. Other conceivable symptoms incorporate colds, bronchitis, an ascent in circulatory strain, unsteadiness, back torment and nose drains, the AP detailed.
