The peak time period for the average beef producer to experience the majority of calf losses has consistently been from the time of birth through the first seven days of life. Weakness is a principal clinical sign of diseases or conditions responsible for mortality including birth trauma, prematurity or dysmaturity, congenital malformations, metabolic defects, intrauterine infection, anoxia or hypoxia, hypothermia, starvation, extremes in birth weight, and post-natal infection. This article discusses anoxia/hypoxia and septicemia in greater detail because of their involvement as a common cause of weakness in the newborn calf.

Cancer cachexia is a syndrome characterised by a marked weight loss, anorexia, asthenia and anaemia. In fact, many patients who die with advanced cancer suffer from cancer cachexia. The cachectic state is invariably associated with the presence and growth of the tumour and leads to a malnutrition status due to the induction of anorexia or decreased food intake. In addition, the competition for nutrients between the tumour and the host leads to an accelerated starvation state which promotes severe metabolic disturbances in the host, including hypermetabolism which leads to an increased energetic inefficiency. Although, the search for the cachectic factor(s) started a long time ago, and although many scientific and economic efforts have been devoted to its discovery, we are still a long way from knowing the whole truth. The main aim of the present review is to summarise and evaluate the different catabolic mediators (both humoural and tumoural) involved in cancer cachexia since they may represent targets for future promising clinical investigations.

The cachectic syndrome, characterized by a marked weight loss, anorexia, asthenia, and anemia is invariably associated with the presence and growth of the tumor and leads to a malnutrition status due to the induction of anorexia or decreased food intake. In addition, the competition for nutrients between the tumor and the host leads to an accelerated starvation state, which promotes severe metabolic disturbances in the host, including hypermetabolism, which leads to an increased energetic inefficiency. Although the search for the cachectic factor(s) started a long time ago, and although many scientific and economic efforts have been devoted to its discovery, we are still a long way from knowing the whole truth. Present investigation is devoted to revealing the different signaling pathways, in particular transcriptional factors involved in muscle wasting. The main aim of the present review is to summarize and evaluate the different molecular mechanisms and catabolic mediators (both humoral and tumoral) involved in cancer cachexia since they may represent targets for future promising clinical investigations.

Patients with non-curable cancer represent a large and heterogeneous group in which malnutrition and weight loss is a frequent finding. This article is based on relevant literature and our own clinical experience. For every patient a thorough examination of possible underlying causes should be explored and corrected as soon as possible (secondary cachexia). However, in many patients primary cachexia is the cause, a catabolic condition where muscle protein and lipids are degraded and even aggressive nutrition will not reverse the process. This condition is very different from starvation. Metoclopramide, corticosteroids and gestagens can relieve symptoms as anorexia, chronic nausea and asthenia which frequently occur in patients with cachexia. Treatments that may maintain or increase muscle function and modulate inflammatory processes are new approaches, such as eicosapentaneoic acid, adenosine triphosphate, specific amino acids and nonsteroidal antiinflammatory drugs. Nutrition is an integrated part of supportive therapy to all cancer patients, unless expected survival is short. At this time in life, nutrition will not influence survival and focus should be on symptom control.

Cancer cachexia is a syndrome characterized by a marked weight loss, anorexia, asthenia and anemia. The degree of cachexia is inversely correlated with the survival time of the patient and it always implies a poor prognosis. Lean body mass depletion is one of the main features of cachexia and it involves not only skeletal muscle but also affects cardiac protein. The cachectic state is invariably associated with the presence and growth of the tumour and leads to a malnutrition status due to the induction of anorexia or decreased food intake. In addition, the competition for nutrients between the tumour and the host leads to an accelerated starvation state which promotes severe metabolic disturbances in the host, including hypermetabolism which leads to an increased energetic inefficiency. Unfortunately, at the clinical level, cachexia is not treated until the patient suffers from a considerable weight loss and wasting. Therefore, it is of great interest to analyze possible early markers of the syndrome. In the present review both metabolic and hormonal markers are described. Although the search for the cachectic factor(s) started a long time ago, and although many scientific and economic efforts have been devoted to its discovery, we are still a long way from fully understanding the underlying basis for this syndrome. The suggested mediators (associated with both depletion of fat stores and muscular tissue) can be divided into two categories: of tumour origin (produced and released by the neoplasm) and humoural factors (mainly cytokines). One of the aims of the present review is to summarize and evaluate the different catabolic mediators (both humoural and tumoural) involved in cancer cachexia, since they may represent targets for clinical investigations. Additionally, an overview of the main therapeutic approaches for the treatment of the cachectic syndrome is presented.
